The diameter, D, of a sphere is 7.4mm. Calculate how he spheres volume, V.
Given :
The diameter D of sphere is 7.4 mm .
To Find :
The volume of sphere.
Solution :
Radius of sphere is r = D/2 .
r = 3.7 mm .
We know, volume of sphere is given by :
[tex]V = \dfrac{4\pi r^3}{3}\\\\V = \dfrac{4\times 3.14 \times 3.7}{3}\ mm^3\\\\V = 15.5 \ mm^3[/tex]

A car salesman will make $1400 salary this month and will earn an extra $500 each time he sells a car. Write an equation for the situation. Determine how much money he will make if he sells 7 cars.
Given:
Fixed salary = $1400
Additional salary = $500 each time he sells a car.
To find:
The equation for the situation and how much money he will make if he sells 7 cars.
Solution:
Let y be the total salary of the salesman after selling x cars.
He will earn an extra $500 each time he sells a car. So, extra money earned by him after selling x cars is 500x.
Total salary = Fixed salary + Additional salary
[tex]y=1400+500x[/tex]
Substituting [tex]x=7[/tex], we get
[tex]y=1400+500(7)[/tex]
[tex]y=1400+3500[/tex]
[tex]y=4900[/tex]
Therefore, the required equation for the given situation is [tex]y=1400+500x[/tex] and the salesman will earn $4900 if he sells 7 cars.

Answer:
c. no
d. yes; AA postulate
Step-by-step explanation:
c. The marked sides have the same ratio ...
20/14 = 10/7 = 64/44.8
However, the angle between them is not marked as being the same. We cannot conclude the triangles are similar.

d. Missing angle R is 180° -32° -52° = 96°. So, two of the angles in the triangles match. (32° and 96°) ∆RQJ ~ ∆VKX by the AA postulate.

The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the second mark, 3 dots above the third mark, 1 dot above the fourth mark and 1 dot above the sixth mark.

Find the area of the composite shape. Use 3.14 for π and round to the nearest hundredth.
___ square inches
Answer:
49.12 in²
Step-by-step explanation:
The composite figure here is a semicircle and a triangle :
Area of triangle = 1/2 * base * height
Base of triangle = 8 inches ; height = 6 inches
Area of triangle = 1/2 * 8 * 6 = 48/2 = 24 in²
Area of semicircle = 1/2 * πr²
Radius = 4 in
Area of semicircle = 1/2 * 3.14 * 4² = 25.12 in²
Area of composite figure :
Area of triangle + Area of semicircle
(24 in² + 25.12 in²)
= 49.12 in²

[tex]D = (3,3)[/tex]
[tex]m : n =5:2[/tex]
Required
The y coordinate
When a line is divided into segments, by ratios.
The formula is:
[tex](x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]
By comparison:
[tex]y = \frac{my_2 + ny_1}{m + n}[/tex]
Where:
[tex]y_1 = 1; y_2 = 3[/tex]
[tex]m : n =5:2[/tex]
So, we have:
[tex]y = \frac{5*3 + 2*1}{5 + 2}[/tex]
[tex]y = \frac{15 + 2}{7}[/tex]
[tex]y = \frac{17}{7}[/tex]

Out of 270 apartments in a complex, 174 are subleased.
Answer:
96
Step-by-step explanation:
Out of 270 apartments in a complex, 174 are subleased.
Given that :
Total number of apartments in complex = 270
Number subleased = 174
The complement of event A = not A
Therefore, The complement in this scenario is NOT SUBLEASED ;
Hence, the Number of apartments in complex not subleased is :
Total apartment in complex - number subleased
270 - 174 = 96

[tex]7y-10[/tex]
Step-by-step explanation:
[tex]9y-\frac{1}{2}\left(4y+20\right)[/tex]
To simplify this expression, first use the distributive property to distribute [tex]\frac{1}{2}[/tex].
[tex]9y-\frac{1}{2}(4y)+-\frac{1}{2}(20)[/tex]
Simplify.
[tex]9y+-2y+-10[/tex]
Combine like terms, [tex]9y[/tex] and [tex]-2y[/tex].
[tex]7y-10[/tex]
The simplification of [tex]9y-\frac{1}{2}(4y+20)[/tex] is [tex]7y-10[/tex].

Segment AB, with endpoints A(-6,9) and B(12, -3), is dilated by a scale factor of 2/3 centered at the origin. What are the coordinates of A'?
9514 1404 393
Answer:
A'(-4, 6)
Step-by-step explanation:
When dilation is about the origin, the image points are the preimage points multiplied by the scale factor.
A' = (2/3)A = (2/3)(-6, 9)
A' = (-4, 6)

The spinner below shows 5 equally sized slices. Yolanda spun the dial 20 times and got the following results Outcome Grey 7 White 7 Black 6
Number of Spins
. Fill in the table below. Round your answers to the nearest thousandth. (a) Assuming that the spinner is fair, compute the theoretical probability of landing on grey.
(b) From Yolanda's results, compute the experimental probability of landing on grey.
(c) Assuming that the spinner is fair, choose the statement below that is true:
As the number of spins increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal.
As the number of spins increases, we expect the experimental and theoretical probabilities to become farther apart.
The experimental and theoretical probabilities must always be equal.
Answer:
Step-by-step explanation:
There are 5 equal areas. 2 of them are gray
2/5 = 0.4
P(gray) = 0.4
The experimental probability is 7/20 = 0.35
The first statement is the correct one. Computers like figuring out these kinds of questions. If you did this a million times, you would come very close, if not exactly, to 0.4
