Converting a Percent to a Decimal
a) The percentage is 73%.
b) The ratio is 73:27
d) The decimal form is 0.73
e) The fraction is 73/100
What percentage is shaded?The percentage of the model that is shaded is given by:
P = 100%*(shaded squares)/(total number of squares)
There are 100 squares in total, of these 73 are shaded, then the percentage is:
P = 100%*(73)/100 = 73%
b) The ratio is "shaded squares to non shaded squares"
There are 73 shaded squares and 27 non-shaded ones, then the ratio is 73:27
c) To get the equivalent decimal to a percentage, just divide it by 100%.
p = 73%/100% =0.73
d) The equivalent fraction is the fraction we wrote on the first step, it is:

The electric field at points on the y-axis above the uppermost charge is given by \(E= kq/(a^{2}+y^{2} )^{(3/2)} ,ex=0, ey=kq/(a^{2}+y^{2} )^{(3/2)}\).
The electric field at points on the y-axis above the uppermost charge can be calculated by finding the electric field due to each of the three charges and summing them. This calculation requires the use of Coulomb's law, which states that the force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. The electric field due to a single charge is proportional to the charge and inversely proportional to the square of the distance from the charge to the point at which the field is being calculated.
By using the equations for the electric field due to each charge and the vector sum of their electric fields, an expression for the electric field at points on the y-axis above the uppermost charge can be obtained. The final expression would likely be a function of q, a, x, y, and the Coulomb constant k.

x =x=x, equals ^\circ ∘
Answer:
x = 64
Step-by-step explanation:
A circle equal 360 degrees
180 + 90 + x + 26 = 360
Combine like terms
296+x = 360
Subtract 296 from each side
296+x-296 = 360-296

Suppose that the readings on the thermometers are normally distributed with a mean of 0∘ and a standard deviation of 1.00∘C.
If 12% of the thermometers are rejected because they have readings that are too high, but all other thermometers are acceptable, find the reading that separates the rejected thermometers from the others.
The reading that separates the rejected thermometers from the others is given as follows:
1.175 ºC.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a normally distributed variable that has mean represented by \(\mu\) and standard deviation represented by \(\sigma\) is obtained by the equation presented as follows:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation for this problem are given as follows:
\(\mu = 0, \sigma = 1\)
The 12% higher of temperatures are rejected, hence the 88th percentile is the value of interest, which is X when Z = 1.175.
Hence:
1.175 = X/1
X = 1.175 ºC.

The solution of the graph,

Find the unknown side length, x. Write your answer in simplest radical form.
A. 3
B. 34
C. 6.
D. 41
Answer:
√41
Step-by-step explanation:
Considering the sides with lengths 48 and 52 units, we would use Pythagoras theorem to find the third side. Let that side be t
52² = 48² + t²
t² = 52² - 48²
= 2704 - 2304
= 400
t = √400
= 20
Considering the next triangle with sides t (20 units) and 12 units, again using the theorem
20² = 12² + y²
where y is the third side
400 = 144 + y²
y² = 400 - 144
= 256
y = √256
= 16 units
Considering the triangle with two sides given as 5 and 13 units, the third side (which is part of the 16 units calculated earlier)
13² = 5² + u²
where u is the 3rd side
169 = 25 + u²
u² = 169 - 25
u² = 144
u = √144
u = 12
The other part of the side of that triangle
= 16 - 12
= 4
Considering the smallest triangle whose sides are x, 5 and 4,
x² = 5² + 4²
= 25 + 16
= 41
x = √41

Car 1 travels 8 miles north and then 6 miles east. Car 2 travels 12 miles south and 9 miles west. Distance in miles between the cars
Answer:
\(\text{Distance in miles between the cars = 25 miles}\)
Step-by-step explanation:
We can solve this problem by treating the locations of the cars as points on a X-Y coordinate plane
Let the X axis represent the horizontal distances with direction East being positive and direction West being negative
Let Y represent the vertical distance with North being positive and South being negative
The initial position of both cars is (0, 0)
Car 1 travels 8 miles north so it's y coordinate becomes 0 + 8 = 8 and point coordinates become (0, 8)
It then travels 6 miles east which puts its x-coordinate at 0 + 6 = 6 with y-coordinate staying at 8
So position of car 1 is (6, 8)
Car 2 travels 12 miles south first so new y-coordinate = 0- 12 = -12
It then travels 9 miles west so new x-coordinate = 0 - 9 = -9
Position of car 2 is (-9, -12)
The distance between these two points, d is the distance between the cars
The distance between any two points (x1, y1) and (x2, y2) is given by the distance formula
\(d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}\)
If we let (x1, y1) represent the position of car 2 and (x2, y2) the position of car 1 then
\(d = \sqrt {(6 - (-9))^2 + (8 - (-12))^2}\\\\d = \sqrt {(15)^2 + (20)^2}\\\\d = \sqrt {{225} + {400}}\\\\d = \sqrt {625}\\\\d = 25\)
So the distance between the two cars = 25 miles

find the product in lowest terms 24/18x2/17x34/3
Answer:
Step-by-step explanation:
To find the product of the given fractions in lowest terms, we can multiply the numerators and denominators together, and then simplify the resulting fraction:
(24/18) * (2/17) * (34/3)
First, we can simplify the fractions by reducing any common factors in the numerators and denominators:
24/18 = (212)/(29) = 12/9 = 4/3
2/17 = 2/17
34/3 = (2*17)/3 = 34/3
Now we can multiply the simplified fractions:
(4/3) * (2/17) * (34/3) = (4234)/(3173) = 272/153
The product of the given fractions in lowest terms is 272/153.
The rule c=6.3r gives the approximate circumference c of a circle as a function of its radius r. Identify the independent and dependent variables in this relationship
The circumference (c) is the dependent variable.
The radius (r) is the independent variable.
How to identify the independent and dependent variables in a relationship?
An independent variable is a variable that does not depend on any other variable for its value
A dependent variable is a variable depend on any other variable for its value.
In the rule c = 6.3r, the circumference (c) of a circle depends on the radius for its value while the radius (r) does not depend on the circumference for its value.
Thus, the circumference (c) is the dependent variable while the radius (r) is the independent variable
