3x = 60 divide both sides by 3
x = 20
what is the property of 3x(5x7)=(3x5)7
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.
A study wants to show that the most expensive cars get stopped for speeding more often. Which of the following issues is most likely to bias the results?
Group of answer choices
The gas mileage of the various cars
The state the car comes from
Expensive cars draw more attention than cheaper cars
The functionality of the radar gun used for gauging speed
The age of the tires on the cars
Expensive cars draw more attention than cheaper cars is most likely to bias the results.
The capacity of expensive automobiles to provide a smooth ride or to filter out road irregularities so that the occupants may drive in the utmost comfort is typically associated with their plush ride quality.
The underlying engineering, including the suspension design, weight distribution, and wheel size, affects ride quality. The suspension in most low-cost vehicles is built to function well in most conditions.
Handling is the ease with which a vehicle must undergo quick or successive changes in directions without upsetting the driver. Handling depends on the chassis design and suspension design. Usually, handling is inversely proportional to ride quality, as great handling vehicles require a stiffer suspension.

the probability that a student selected in our class will pass mathematics test is 2/3 how many students are likely to feel mathematics in the art class with 69 students
Out of 69 students in the art class, around 23 are expected to fail the mathematics test, assuming the probability of passing given is 2/3.
To determine how many students are likely to fail mathematics in the art class, we need to use the given probability of passing the mathematics test, which is 2/3.
First, let's find the probability of failing the mathematics test. Since passing and failing are complementary events (i.e., if the probability of passing is p, then the probability of failing is 1 - p), we can calculate the probability of failing as 1 - 2/3, which simplifies to 1/3.
Now, let's consider the art class, which has a total of 69 students. If the probability of failing mathematics is 1/3, then approximately 1/3 of the students in the art class are likely to fail the mathematics test.
To find the number of students likely to fail, we multiply the probability of failing (1/3) by the total number of students in the art class (69).
(1/3) * 69 ≈ 23
Therefore, approximately 23 students are likely to fail mathematics in the art class of 69 students based on the given probability of passing the mathematics test.

Greetings from Brasil...
According to the statement of the question:
X² = 20Let's apply square root to both members
√X² = √20
X = √20
20 = 2² · 5 so √20 = √2² · 5 = 2√5
X = √20 or X = 2√5 or X = 4.4721
How many roots do the functions have in common f(x)=x^2+x-6
To find the common roots between two functions, we need to find the roots (or solutions) of each function individually and then identify the shared solutions.
For the function f(x) = x^2 + x - 6, we can find the roots by setting the function equal to zero and solving for x:
x^2 + x - 6 = 0
To factorize this quadratic equation, we need to find two numbers that multiply to -6 and add up to 1 (the coefficient of x). The numbers that satisfy these conditions are 3 and -2:
(x + 3)(x - 2) = 0
Setting each factor equal to zero:
x + 3 = 0 or x - 2 = 0
Solving for x in each equation:
x = -3 or x = 2
Therefore, the function f(x) = x^2 + x - 6 has two roots: x = -3 and x = 2.
To find the common roots between this function and another function, we would need to know the second function. If you provide the second function, I can help determine if there are any shared roots.

Find the measure of CD.
mCD= [?] degrees
Given:
A circle with radius 7 units and chord CD = 7 units.
To find:
The measure of arc CD.
Solution:
Let O be the center of the circle.
In triangle OCD,
\(OC=7\) (Given)
\(OC=OD=7\) (Radii of same circle)
\(CD=7\) (Given)
Since \(OC=CD=OD\) all sides are equal, therefore, the triangle OCD is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60 degrees. So,
\(m\angle COD=60^\circ\)
The measure of central angle is equal to the measure of corresponding arc.
\(m(arcCD)=m\angle COD\)
\(m(arcCD)=60^\circ\)
Therefore, the measure of arc CD is 60 degrees.

Answer:
Because If we tried to define scalar multiplication we would run into problems. No there are not any special accommodations.
Step-by-step explanation:
Given the definitions of f(x) and g(x) below, find the value of (fog)(-3).
f(x) = 3x² - 7x-3
g(x) = -4x - 10
The value of the composite function (f o g)(3) is 1603
How to evaluate the composite function?The functions are given as
f(x) = 3x² - 7x - 3
g(x) = -4x - 10
Next, calculate (f o g)(x) using
(f o g)(x) = f(g(x))
So, we have
(f o g)(x) = 3(-4x - 10)² - 7(-4x - 10) - 3
Substitute 3 for x.
So, we have
(f o g)(3) = 3(-4 x 3 - 10)² - 7(-4 x 3 - 10) - 3
Evaluate
(f o g)(3) = 1603
Hence, the value of the composite function (f o g)(3) is 1603

Caleb brought groceries and paid $1.60 in sales tax. The sales tax rate is 2.5%. What was the price of caleb’s groceries, before tax?
Answer:
$64
Step-by-step explanation:
We can set up a percentage proportion to find the value Caleb's groceries before tax.
\(\frac{1.60}{x} = \frac{2.5}{100}\)
We can cross multiply to find the value of x.
\(100\cdot1.60=160\\\\160\div2.5=64\)
So the original cost before tax was $64.
Hope this helped!
Answer:
$1.64
Step-by-step explanation:
We need to find the before tax price so let that be x
100-2.5% = 97.5% (since this is the reduction before the sale)
Turn this percentage into a decimal so 0.975
To find x we must remember this price multiples 0.975 to give us $1.60
x * 0.975 = 1.60
x = 1.60 / 0.975
x = 1.64 (2dp)

There are 10 Superscript 9 bytes in a gigabyte. There are 10 Superscript 6 bytes in a megabyte. How many times greater is the storage capacity of a 1-gigabyte flash drive than a 1-megabyte flash drive?
3 times greater
10 times greater
1,000 times greater
3,000 times greater
A 1-gigabyte flash drive has 1000 times more storage space than a 1-megabyte flash disk. The right response is thus "1,000 times greater."
To solve this problem
We need to find the ratio between the two capacities.
Given that there are \(10^9\) bytes in a gigabyte and\(10^6\) bytes in a megabyte, we can calculate the ratio as follows:
Ratio = (1 GB) / (1 MB)
= \((10^9 bytes) / (10^6 bytes)\)
= \(10^(9 - 6)\)
=\(10^3\)
= 1000
Therefore, A 1-gigabyte flash drive has 1000 times more storage space than a 1-megabyte flash disk. The right response is thus "1,000 times greater."

Step-by-step explanation:
Question 1(a) When completing the square for a quadratic equation in the form ax² + bx + c where the leading coefficient is one, we need to add the square of half the coefficient of the x-term:
\(x^2-14x+\left(\dfrac{-14}{2}\right)^2\)
\(x^2-14x+\left(-7\right)^2\)
\(x^2-14x+49\)
We have now created a perfect square trinomial in the form a² - 2ab + b². To factor a perfect square trinomial, use the following formula:
\(\boxed{a^2 -2ab + b^2 = (a -b)^2}\)
Therefore:
\(a^2=x^2 \implies a=1\)
\(b^2=49=7^2\implies b = 7\)
Therefore, the perfect square trinomial rewritten as a binomial squared is:
\(x^2-14x+\boxed{49}=\left(x-\boxed{7}\right)^2\)
(b) When completing the square for a quadratic equation where the leading coefficient is not one, we need to add the square of the coefficient of the x-term once it is halved and divided by the leading coefficient, and then multiply it by the leading coefficient:
\(9x^2 + 30x +9\left(\dfrac{30}{2 \cdot 9}\right)^2\)
\(9x^2 + 30x +9\left(\dfrac{5}{3}\right)^2\)
\(9x^2 + 30x +9 \cdot \dfrac{25}{9}\)
\(9x^2 + 30x +25\)
We have now created a perfect square trinomial in the form a² + 2ab + b². To factor a perfect square trinomial, use the following formula:
\(\boxed{a^2 +2ab + b^2 = (a +b)^2}\)
Therefore:
\(a^2=9x^2 = (3x)^2 \implies a = 3x\)
\(b^2=25 = 5^2 \implies b = 5\)
Therefore, the perfect square trinomial rewritten as a binomial squared is:
\(9x^2 + 30x +\boxed{25}= \left(3x +\boxed{5}\right)^2\)
\(\hrulefill\)
Question 2(a) Factor out the leading coefficient 3 from the given expression:
\(3x^2-24x+48=3\left(x^2-\boxed{8}\:x+\boxed{16}\right)\)
We have now created a perfect square trinomial in the form a² - 2ab + b² inside the parentheses. To factor a perfect square trinomial, use the following formula:
\(\boxed{a^2 -2ab + b^2 = (a -b)^2}\)
Factor the perfect square trinomial inside the parentheses:
\(=3\left(x-\boxed{4}\right)^2\)
(a) Factor out the leading coefficient 1/2 from the given expression:
\(\dfrac{1}{2}x^2+8x+32=\dfrac{1}{2}\left(x^2+\boxed{16}\:x+\boxed{64}\right)\)
We have now created a perfect square trinomial in the form a² + 2ab + b² inside the parentheses. To factor a perfect square trinomial, use the following formula:
\(\boxed{a^2+2ab + b^2 = (a +b)^2}\)
Factor the perfect square trinomial inside the parentheses:
\(=\dfrac{1}{2}\left(x+\boxed{8}\right)^2\)

how do i get the perimeter of the first triangle?
Answer:
perimeter: 3:4area: 9:16Step-by-step explanation:
The question is about scale factors. The scale factor is the ratio of corresponding sides.
Scale factorWe have to assume the figures are similar, and that corresponding sides are marked. The bottom sides of the figures have the ratio ...
red : blue = 6 : 8
This ratio can be reduced to lowest terms by factoring out 2:
scale factor = red : blue = 3 : 4
This scale factor applies to all of the linear measures, one of which is perimeter. The ratio of perimeters is 3 : 4.
Area scale factorArea is measured in square units. The scale factor for area is the square of the scale factor for linear measures.
area scale factor = red : blue = 3² : 4² = 9 : 16
The ratio of areas is 9 : 16.

If 15% of the customers total is $98,880, then the sum total equals what
The sum total by the given data is equals to $658,880.
We are given that;
Percent=15%
Amount= $98,880
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
To divide by a percentage, we can convert it to a decimal by moving the decimal point two places to the left. This gives us:
15% = 0.15
To divide by 0.15, we can multiply by its reciprocal, which is 1/0.15. This gives us:
$98,880 / 0.15 = $98,880 x 1/0.15
To multiply by 100, we can move the decimal point two places to the right. This gives us:
$98,880 x 1/0.15 x 100 = $658,880
Therefore, by the percentage the answer will be $658,880.
