which line has a slope of zero? (Hint:Think Hoy VUX/slpe man)

Answer:

?? what are the answer choices?

Step-by-step explanation:

Your answer: A  −14 × {23 + (−47)} = [−14 × 23] + [−14 × (−47)]  This example demonstrates the distributive property of multiplication over addition for rational numbers, which states that for any rational numbers a, b, and c: a × (b + c) = (a × b) + (a × c).

The correct answer is A: −14 × {23 + (−47)} = [−14 × 23] + [−14 × (−47)]. This is an example of the distributive property of multiplication over addition for rational numbers because we are multiplying −14 by the sum of 23 and −47, and we can distribute the multiplication to each term inside the parentheses by multiplying −14 by 23 and −14 by −47 separately, and then add the two results together. This is the basic definition of the distributive property of multiplication over addition. Option B shows the distributive property of multiplication over subtraction, option C shows the product of multiplication and addition, and option D is not a valid equation.

The independent variables, the ones that are intentionally manipulated, are temperature and surface time.

The dependent variable, the one that you measure the response in, is the reaction time.

The physical concept of temperature indicates in the numerical form how hot or cold something is. Temperature is measured with a thermometer.

Thermometers are calibrated in numerous temperature scales that historically have depended on various reference factors and thermometric materials for definition. The most common scales are the Celsius scale with the unit image °C (previously referred to as centigrade), the Fahrenheit scale (°F), and the Kelvin scale (okay), the latter being used predominantly for clinical functions. The kelvin is one of the seven base units within the worldwide machine of gadgets (SI).

Absolute zero, i.e. 0 kelvin or −273.15 °C, is the bottom factor within the thermodynamic temperature scale. Experimentally, it can be approached simplest very intently, however, no longer genuinely reached, as diagnosed in the 0.33 law of thermodynamics. it'd be not possible to extract power as the warmth from a body at that temperature.

Answer:

x=38

Step-by-step explanation:

the angles of any triangle always equals 180

so to find x we set up an equation like this: (2x+8)+(2x-18)+X=180

calculate to find x

Combine like terms: (2x+2x+x)+(8+−18)=180

2x+2x+x=5x

8+(-18)=-10

now we have 5x+(-10)=180

Add 10 to 180, then divide 190 by 5.

180+10=190/5=38

x=38

to find the measures put 34 into the angle equations

2(38)-8=58

2(38)+18=84

The required surface area of the new ramp is 361.8 ft².

Given that,
Santiago needs to build a ramp 3 times longer in every dimension than the ramp he has, which is in the shape of a triangular prism with a surface area of 40.2ft².

The scale factor is defined as the ratio of the modified change in length to the original length.

Here,
For the area, the multiplication factor is = 3² = 9
Now,
The surface area of the new ramp = 9 [surface area of the old ramp]
The surface area of the new ramp = 9 × 40.2
The Surface area if the new ramp = 361.8 ft²

Thus, the required surface area of the new ramp is 361.8 ft².

Answer:

y= 5x-3

Step-by-step explanation:

It works with the y=mx+b form. 5 is slope so it is m, and when u do 5(2)=10. In order to get to 7 u must subtract 3, so the answer is y=5x-3! Ur welcome!

The equation of the line that has a slope of 5 and goes through the point (2,7) is y-5x = -3

The formula for calculating the equation of a line in point-slope form is expressed as:

\(y-y_1 = m(x-x_1)\)

m is the slope of the line

(x1, y1) is any point on the line

Given the following parameters

m =5

(x1, y1) = (2, 7)

Substitute the parameters into the given formula;

y - 7 = 5(x - 2)

y - 7 = 5x - 10

y - 5x = -10 + 7

y - 5x = -3

Hence the equation of the line that has a slope of 5 and goes through the point (2,7) is y-5x = -3

Answer: Im pretty sure it's 6

Answer:

see below

Step-by-step explanation:

We can use the law of sines

sin 80             sin B

--------------- = -------------

31                       14

Using cross products

14 sin 80 = 31 sin B

14/31  sin 80 = sin B

.984807753 = sin B

Taking the inverse sin of each side

sin ^ -1 ( .444751888) =  B

26.41 = B

The sum of the angles of a triangle is 180

A+B+C = 180

80 + 26.41 + C =180

106.41 + C = 180

C = 73.59

We can use the law of sines to find c

sin 80             sin 73.59

--------------- = -------------

31                       c

c sin 80 = 31 sin 73.59

c =  31 sin 73.59 / sin 80

c = 30.20

According to recent data, women make up 34% and 26% of workers in science and technology (STEM) fields in Canada and the United States, respectively. The correct option is A. 34% and 26%.

According to recent data, women make up 34% and 26% of workers in science and technology (STEM) fields in Canada and the United States, respectively. This indicates that women are still underrepresented in STEM fields, despite the fact that there has been an effort to attract more women to STEM fields.

In both Canada and the United States, women have made significant progress in breaking down gender barriers in STEM fields. However, there is still work to be done to close the gender gap and increase representation of women in STEM fields.

Women's representation in STEM fields has increased in both Canada and the United States in recent years, but the percentage of women in STEM fields is still significantly lower than the percentage of men.

To solve for q in the equation 2q^2 = 8,

we can start by dividing both sides of the equation by 2:

2q^2/2 = 8/2

Simplifying, we get:

q^2 = 4

To solve for q, we can take the square root of both sides of the equation:

√(q^2) = ±√4

Simplifying, we get:

q = ±2

So, the solutions for q are q = 2 and q = -2.

therefore, he had 181 digital cameras at first

Step-by-step explanation:

manual= x+26

total= digital + manual

240= 3x+82+26+x

x= 240-108/4

Answer:

  181

Step-by-step explanation:

Let d represent the number of digit cameras Mr. Rifkin had at first. Then 240-d is the number of manual cameras he had. The after-donation numbers are ...

  (d -82) . . . digital cameras after donating 82

  (240 -d) -26 . . . manual cameras after donating 26

These values are related by ...

  (d -82) = 3((240 -d) -26)

  4d = 724 . . . . . add 3d+82 and simplify

  d = 181

Rifkin had 181 digital cameras at first.
