Given that the solids are similar, we have:
1. 5/3
2. 4/25
3. 512/13,824
What is the Volume and Surface Area of Similar Solids?If two solids have a surface area of A and B respectively, and a and b are their respective corresponding linear measures, the following ratio would be true for the similar solids:
Surface area for A/Surface area for B = a²/b².
Volume for A/Volume for B = a³/b³.
1. If the two pyramids are similar, therefore:
Ratio of the height of larger to the smaller pyramid = √(525/189) = √(25/9)
Ratio of the height of larger to the smaller pyramid = 5/3
2. Ratio of the linear measure of the smaller prism to the larger prism = ∛(24/375)
= ∛(8/125) = 2/5
Ratio of their surface area = 2²/5²
Ratio of their surface area = 4/25.

A paper cup shaped like a cone has a diameter of 6 centimeters and a slant height of 7.5 centimeters. About how much paper is needed to make the cup
Answer:
22.5 cm^2
Step-by-step explanation:
Amount of paper is going to be measured in area, so we want the surface area of the cone. Since it is a cub it doesn't have a base, so we don't need to count it.
Area of the cone without the base, or what is called the lateral area is pi*r*s where r is the radius and s is the slant height. and of course radius is d/2 where d is the diameter. so let's plug it in. We know diameter is 6 and slant height is 7.5
SA = pi * r * s
SA = pi * d/2 * s
SA = pi * 6/2 * 7.5
SA = 22.5 cm^2
So you will need 22.5 square centimeters of paper.

A local Target store bought 90 pizzas at Pizza Hut for its holiday party. Each guest ate 1/6 of a pizza and there was no pizza left over. How many guests did Target have for the party?
By taking a quotient, we will see that the number of guests is 540.
How to find the number of guests?
Because we know that each guest ate a fixed amount of pizza, and there was no pizza left, we know that the number of guests will be equal to the quotient between the total number of pizzas bought, and the amount of pizza that each guest ate.
This is:
[tex]N = \frac{90}{1/6}[/tex]
We can rewrite that quotient as:
[tex]N = \frac{90}{1} / \frac{1}{6} = \frac{90*6}{1*1} = 540[/tex]
So the number of guests is 540.

sine and cosecant : positive in Q1 and Q2
cosin and secant: positive in Q1 and Q4
tangent and cotangent: positive in Q1 and Q3.
Answer:
Quadrant I
Step-by-step explanation:
In the first quadrant all the 6 functions are positives.
Think instead of (x, y) any point has now the coordinate (cos α, sin α) so in quadrant I we have x, y positive therefore sin α and cos α are positive.
Tangent α is positive because is sinα/cosα = positive /positive = a positive
Cotangent α= 1/tan α = cosα / sinα = positive /positive = a positive
Secant α = 1/cos α = 1/ a positive number = a positive number
Cosecant α = 1/sin α = 1/ a positive number = a positive number

A rectangular prism has a height of 15 centimeters and a width of 6 centimeters. The surface area of the prism is 684 square centimeters. What is the length of the prism?
A. 24 cm
B. 12 cm
C. 9 cm
D. 6 cm
Answer:
Step-by-step explanation:
Let the length be L
Formula
SA = 2Lw + 2Lh + 2wh
Givens
h = 15 cm
w = 6 cm
L = ?
SA = 684 cm^2
Solution
Substitue what you know into the given formula
2*6*L + 2*15*L + 2 * 6 * 15 = 684 Combine
12*L + 30*L + 180 = 684 Combine again
42L + 180 = 684 Subtract 180 from both sides.
42L +180 -180 = 684 - 180
42L = 504 Divide by 42
Answer: L = 12

The probability that the first survey chosen indicates four children in the family, and the second survey indicates one child in the family is 1/5.
What is probability?The surveys are chosen with replacement (the first one is replaced before the second is chosen), and the events are independent.
This means that the probability of both together is the product of each event's probability.
The probability of choosing a survey that indicates 4 children in the family is 8/60 since there are 8 surveys with 4 children out of a total of (9+18+22+8+3) = 60 surveys.
The probability of choosing a survey that indicates 1 child is 9/60 since there are 9 surveys with 1 child out of a total of 60.
Together this gives us;
[tex]= \dfrac{8}{60} \times \dfrac{9}{60}\\\\ =\dfrac{ 72}{360} \\\\ =\dfrac{1}{5}[/tex]
Hence, the probability that the first survey chosen indicates four children in the family, and the second survey indicates one child in the family is 1/5.

Mrs. Burgess will go to the gym on 20 different days this month. A one day pass to the gym costs $9.65. A monthly pass to the gym costs $145. How much will Mrs. Burgess save by buying a monthly pass?
Answer:
Mrs. Burgess will save $48 by buying a monthly pass.
Step-by-step explanation:
Let's compare the one-day pass to the monthly pass by finding how much 20 one-day passes will cost.
Multiply the price for a one day pass, $9.65, to the gym by 20 days:
$9.65 * 20 = $193Compare this price to the monthly pass price by subtracting these values.
$193 - $145 = $48If Mrs. Burgess buys the monthly pass of $145 instead of buying 20 day passes for $193, she will save $48.
If you start with the equation x-6, what equation do you have when you add 3 to both sides
