Answer:
p is proportional to q, r, t, and inversely proportional to s
Step-by-step explanation:
Assuming k is a "constant of proportionality," the value of p is directly proportional to each of the numerator variables: q, r, t. P is inversely proportional to the denominator variable, s.

1. What is the volume, in cubic centimeters, of the sphere shown below? Use 3.14
for Pi
Answer:
113.04 cm³
Step-by-step explanation:
diameter = 6cm
so radius = 3cm
Volume of sphere = [tex]\frac{4}3}[/tex][tex]\pi r^3[/tex]
= 4 * 3.14 * 3 * 3 *3 / 3
= 4 * 28.26
= 113.04 cm³
A school cafeteria offers three lunch options on Mondays: spaghetti, sub sandwiches, or salad bar. The following two-way frequency table shows the number of each lunch option ordered on a given.
What percentage of teachers ordered the salad bar?
OA. 19.48%
B. 10.21%
C. 2.38%
D. 65.22%
Answer: 65.22%
Step-by-step explanation: 15 is more than half of 23 which means it can’t be the other options because the others aren’t more than half.
65.22 % of teachers ordered the salad bar
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
According to the question
A school cafeteria offers three lunch options on Mondays:
Spaghetti, sub sandwiches, or salad bar.
Percentage of teachers ordered the salad bar
Total number of teachers = 23
Total number of teachers ordered the salad bar = 15
= [tex]\frac{15}{23}[/tex]
= 0.6522

how do you write 15/60 as a percent
Answer:
25%
Step-by-step explanation:
Answer:
15/60 as a percentage is 25%
Step-by-step explanation:
When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form. Now we can see that our fraction is 25/100, which means that 15/60 as a percentage is 25%. And there you have it!

[tex] \boxed{(6, -3)} [/tex]
Step-by-step explanation:
Given the ratio 5:3
and Points A and B where A is located at (-6, 3), and B is located at (26, -13).
Let point A be [tex] (x_{1}, y_{1}) [/tex], and let point B be [tex] (x_{2}, y_{2}) [/tex].
(-6, 3) → [tex] (x_{1}, y_{1}) [/tex].

ur steps would be 9*1*9 = 9^3
Step-by-step explanation:
Any number in the power of 0 = 1
Answer:
9^4
Step-by-step explanation:
Let's review the equation:
9 · 9^0 · 9^3
Anything to the power of 0 is equal to one, so 9^0 is one
That leaves us with 9 · 1 · 9^3
9 · 1 = 9
9^1 · 9^3 = 9^4
so..

LT1 10th grade level. How tall I’d the building?
Answer: 99.2 m
Step-by-step explanation:
Given
The height of the flagpole is 35 m which is situated at 60 m
It is clear that the angle of elevation for the flagpole and building is the same, let say [tex]\theta[/tex]
from the figure, we can write
[tex]\Rightarrow \tan \theta=\dfrac{35}{60}=\dfrac{h}{170}\\\\\Rightarrow h=170\times \dfrac{35}{60}\\\\\Rightarrow h=99.166\approx 99.2\ m[/tex]
Thus, the height of building is 99.2 m
Two angles, m
• The m ABC is 54°
• The m JKL is (8x)".
What is the value of x?
Answer: 15.75°
Step-by-step explanation:
Supplementary angles simply refers to the angles that add up to 180°. The angles given in this case are 54° and 8x.
To find the value of x goes thus:
54° + 8x = 180°
8x = 180° - 54°
8x = 126°
x = 126°/8
x = 15.75°
Therefore the value of x is 15.75°

Answer: C / 100 units^2
Step-by-step explanation:
The equation to calculate the area of a rhombus is
[tex]Area = \frac{ab}{2}[/tex]
In the picture, you are given a & b.
a equals the entire vertical line. So 5 + 5 = 10. 10 is a
b equals the entire horizontal line. So 10 + 10 = 20. 20 is b.
According to the equation you multiply a times b.
[tex]Area = \frac{(10)(20)}{2}[/tex] 10 x 20 = 200
200 divided by 2 equals 100
so the areas = 100

The side of polygone have length 5,7,8,11&9, the perimeter of similar polygone is 75cm ,finde the length of the side of large polygon?
Answer:
The side lengths of the larger polygon are;
15 cm
20.625 cm
16.875 cm
9.375 cm
13.125 cm
Step-by-step explanation:
Firstly, we need to calculate the perimeter of the first polygon
Mathematically, we can get this by adding the side lengths together
We have this as;
5 + 7 + 8 + 11 + 9
= 40 cm
so we have the ratio of the lengths of both as;
75 cm/40 cm = 1.875
Now, we simply will multiply the lengths of the smaller polygon by 1.875
So we have the side lengths of the bigger polygon as;
1.875 * 5 = 9.375 cm
1.875 * 7 = 13.125 cm
1.875 * 8 = 15 cm
1.875 * 9 = 16.875 cm
1.875 * 11 = 20.625 cm

Step-by-step explanation:
Grayson ran 2 1/2 miles around the track .each lap is 5/6 of a mile .how many laps did Grayson run?
Given:
Number of miles covered = [tex]2\dfrac{1}{2}[/tex]
Length of each lap = [tex]\dfrac{5}{6}[/tex] of a mile.
To find:
The number of laps.
Solution:
We know that,
[tex]\text{Number of laps}=\dfrac{\text{Number of miles covered}}{\text{Length of each lap}}[/tex]
[tex]\text{Number of laps}=\dfrac{2\dfrac{1}{2}}{\dfrac{5}{6}}[/tex]
[tex]\text{Number of laps}=\dfrac{\dfrac{5}{2}}{\dfrac{5}{6}}[/tex]
[tex]\text{Number of laps}=\dfrac{5}{2}\times \dfrac{6}{5}[/tex]
[tex]\text{Number of laps}=3[/tex]
Therefore, Grayson ran 3 laps.

John had $30 when he got to the
carnival. After riding 5 rides, he had $20
left. If each ride costs the same, what
was the price of each?
Answer:
$2
Step-by-step explanation:
Step-by-step explanation:
Given, John had $30
after riding 5 rides, He had $20
( Let's subtract the balance and the balance he had after ride )
$(30 - 20)
$10
Therefore, Each ride costs = $10 ÷ 5
(dividing 10 and 5, we get 2)= $2
Hence, It took $2 for a ride.

what is the slope of the graph of y= -5/3x + 3/4
Answer:
slope = - [tex]\frac{5}{3}[/tex]
