Here are two similar solid toys. The ratio of surface area of toys R: surface area of toy B is 7:9. The volume of toy B is 20cm^3. Work out the volume of toy A. Give your answer to 3 significant figures 
Answer:
13.7
Step-by-step explanation:
The computation of the volume of toy A is shown below:
7 × k^2=9
k^2= 9 ÷ 7
k=√9 ÷ 7
k = 1.133893419
Now
= 20 ÷ 1.133893419³

plz help find x !!!!!
Answer:
a. 38.5
Step-by-step explanation:
The triangles are similar. That means that the ratios are the same.
x/14 = 11/4
x/31.5 = 11/9
Let's use the top one
x/14 = 11/4
4x/14 = 11
4x = 154
x = 38.5
Suppose a city with population 600,000 has been growing at a rate of 4% per year. If this rate continues, find the population of this city in 25 years.
Answer:
15,600,000
Step-by-step explanation:
We start with our initial population of 600,000. Then multiply that with the rate of 4% (0.04 in decimal, or 1.04 so that the 0.04 is automatically added to the 600,000.)
600,000 · 1.04y = projected populationy = 25600,000 · 1.04(25) = projected populationsimplify!15,600,000 = proejcted populationWhich would be an estimate for 36,004 ÷ 853

Admission to the fair is $15 each ride cost $3 micah spent a total of $36 he spent all of his money on rides and admission
Answer:
7
Step-by-step explanation:
Admission cost = $15
Cost per ride = $3
Total amount spent = $36
We can obtain the number of rides thus :
Let number of rides = x
Admission cost + (cost per ride * number of rides) = total amount spent
15 + 3x = 36
3x = 36 - 15
3x = 21
x = 21 / 3
x = 7
Number of rides = 7

The circumference formula is 168.6
where r is the radius given to us as 26.85, and pi is to be 3.14. In our formula then, we have
.
Doing that multiplication and rounding to the nearest tenth leaves us with a circumference of 168.6 inches.

Find the smallest number such that the remainder is 3 when it is divided by 16,20 or 24.
(step required,thank you)
Answer: 123
Step-by-step explanation:
Foe us to solve this, we have to find the lowest common multiple of 16, 20 and 24 first and then add 3 to the LCM. This goes thus:
Multiples of 16 = 16, 32, 48, 64, 80, 96, 112, 128, 144, 160
Multiples of 20 = 20, 40, 60, 80, 10, 120, 140, 160
Multiples of 24 = 24, 48, 72, 96, 120
Therefore, the Lowe's common multiple is 120.
We then add the remainder of 3 and this will give:
= 120 + 3
= 123
Find the volume of a pyramid with a square base, where the perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm. Round your answer to the nearest tenth of a cubic centimeter.
Answer:
V=2.8cm^3
Step-by-step explanation:
The volume of a pyramid with a square base should be considered as the 2.8 cubic centimeter.
Calculation of the pyramid:Since
perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm.
So, here
we know that
volume of a pyramid = [tex]1/3(length * width * height)[/tex]
And,
perimeter of a square = [tex]4 * length[/tex]
6.9 = 4 x length
So,
length = 1.725
Now the volume is
[tex]= 1/3 * (1.725 * 1.725 * 2.8)[/tex]
= 2.8

The sum of two nonnegative numbers is 50. What is the maximum value of the product of these two numbers ?
Answer:
625
Step-by-step explanation:
Let two number be x and (50-x).
The product of numbers be x(50-x).
P = 50x-x²
For maximizing the product,
[tex]\dfrac{dP}{dx}=0\\\\\dfrac{d}{dx}(50x-x^2)=0\\\\50-2x=0\\\\50=2x\\\\x=25[/tex]
So, the maximum product, P = 50(25)-(25)²
P = 625
Hence, the maximum value of the product of these two numbers is 625.

A school fundraiser has a minimum target of $500. Faculty have donated $100 and there
are 12 student clubs that are participating with different activities. How much money
should each club raise to meet the fundraising goal?
12x - 100 > 500
12x +100 > 500
12x- 100 > 500
12x + 100 > 500
12x - 100 < 500
12x + 100 < 500
Answer:
Each student club must contribute $ 33.33 in order to meet the fundraising goal.
Step-by-step explanation:
Given that a school fundraiser has a minimum target of $ 500. Faculty have donated $ 100 and there are 12 student clubs that are participating with different activities, to determine how much money should each club raise to meet the fundraising goal, the following calculation must be performed:
(500 - 100) / 12 = X
400/12 = X
33,333 = X
Thus, each student club must contribute $ 33.33 in order to meet the fundraising goal.
