Jim is painting the inside of a circular helicopter pad. How many cans of paint would he need if the pad is 50 feet across and each can of paint covers about 200ft^2?
Please add how you got your answer and thank you very much!
Answers
You need to find the area of the circular pad.
Circle Area= πr^2
we need the radius which is half of the diameter given
=π(50÷2)^2
=(3.14)(25)^2
=(3.14)(625)
=1,963.495 ft^2 total area
STEP 2:
Find how much paint is needed by dividing a can's coverage into what's needed.
=1963.495 ÷ 200
=9.817
=10 cans are needed (because you cannot buy a part of a can, you need to round up)
ANSWER: 10 cans are needed
Hope this helps! :)
Final answer:
To find out how many paint cans Jim needs, calculate the area of the circular pad using the formula πr^2 and divide by the coverage area of one can. For a 50 feet diameter pad, Jim would need approximately 10 cans of paint.
Explanation:
To calculate the number of paint cans needed, we first need to find the area of the circular helicopter pad. The diameter of the pad is given as 50 feet, so the radius is half of that, which is 25 feet. The area A of a circle is calculated using the formula A = πr^2, where r is the radius.
Substituting the radius into the formula gives:
A = π(25 feet)^2
A = 3.14159 × (25 feet) × (25 feet)
A = 3.14159 × 625 feet²
A = 1963.495 feet²
Since each can covers about 200 square feet, we divide the total area by the coverage area per can:
Number of cans = 1963.495 feet² / 200 feet²/can
Number of cans ≈ 9.82 cans
Since Jim cannot buy a fraction of a can, he would need to round up, meaning he would need 10 cans of paint to cover the helicopter pad.

answer
x = 50.6 cm
Answer:
[tex]x=50.6cm[/tex]
Step-by-step explanation:
Triangle MAB is similar to triangle MNP
Since the triangles are similar, the corresponding ratios are in the same proportion.
Therefore we can write the relation;
[tex]\frac{|MB|}{|MP|}=\frac{|MA|}{|MN|}[/tex]
[tex]\frac{x}{72.6}=\frac{46.2-14}{46.2}[/tex]
This implies that;
[tex]\frac{x}{72.6}=\frac{32.2}{46.2}[/tex]
We multiply both sides by 72.6 to get
[tex]\frac{x}{72.6}\times 72.6=\frac{32.2}{46.2}\times72.6[/tex]
[tex]\Rightarrow x=50.6[/tex]
Hence the value of [tex]x[/tex] is 50.6 cm
Question: A chicken soup recipe calls for 11 cups of chicken stock. How much is this in quarts?

Answers
To solve this problem, we need to convert the different units.
Since
1 pint = 2 cups
11 ÷ 2 = 5.5
Since
1 quart = 2 pints
5.5 ÷ 2 = 2.25
So, the amount of chicken stock needed is 2.25 quarts.

how do you solve:
18(18)=x(x+15)
Answers
[tex]18(18)=x(x+15)[/tex]
The parentheses indicate multiplication; the 18(18) on the left side of the equation is 18 * 18. On the right side of the equation, you have x(x + 15); to simplify this, you would distribute the x--that means multiply each term inside the parentheses by x. This is the Distributive Property: [tex]a(b + c) = ab + ac[/tex]. Let's do that.
[tex]18(18)=x(x+15)[/tex]
[tex]324= x^{2} +15x[/tex]
Now, you can subtract 324 from each side to set the equation equal to 0.
[tex]324= x^{2} +15x[/tex]
[tex]324-324= x^{2} +15x-324[/tex]
[tex]0= x^{2} +15x-324[/tex]
This is a quadratic equation; to solve it, we may factor (if the equation is able to be factored) or we can use the Quadratic Formula. Let's see if we can factor. To factor, find two numbers whose sum is 15 and whose product is -324. Since 324 is negative, we know one of the numbers is negative and one of the numbers is positive (a negative times a positive is always negative), and that means one of the numbers is greater than 15...
27 - 12 = 15
27 * -12 = -324
The factored polynomial is: (x + 27)(x - 12).
To find its solutions, set the factors equal to 0 and solve for x.
x + 27 = 0
x = -27
x - 12 = 0
x = 12
Answer:
The solution of [tex]18(18)=x(x+15)[/tex] is -27 and 12.

3. The area of a triangle can be given by (just plug and chug as always):
[tex]A_t = \frac{1}{2} bh = \frac{1}{2}(3)(4) = 6ft^2 [/tex]
The area of the triangle is 6ft².
4. I will divide into a triangle and a rectangle (because the actual equation for the area of a pentagon requires it to be a perfect pentagon). Let's do the triangle first (height is 3 because you subtract 12 from 15):
[tex]A_t = \frac{1}{2} bh = \frac{1}{2}(8)(3) = 12m^2[/tex]
[tex]A_r = bh = 12(8) = 96m^2[/tex]
Now we just add them:
[tex]96+12 = 108m^2[/tex]
So, the area of that pentagon is 108m².
5. You are actually wrong on this one because the area of a triangle is:
[tex]A_t = \frac{1}{2}bh [/tex]
So, just halve your answer and it will be correct.
6. We can just split it into 4 triangles of equal area and then multiply the area of 1 triangle by 4 to get the total area. Let's do just that:
[tex]A_t = \frac{1}{2}bh = \frac{1}{2}(2.5)(5) = 6.25cm^2 [/tex]
Multiply by 4 to get total area:
[tex]6.25*4 = 25cm^2[/tex]
So, the area of the given rhombus is 25cm².

There is a one time fee of $27 to join the gym the monthly cost of using the gym is $18 write any Quezon for the relationship that gives the total cost Y in dollars of joining the gym and using it for X months
Answers
y represent the total cost
18 represents the cost per month
x represent the number of months
27 is the initial fee
The total cost Y in dollars of joining the gym and using it for X months can be determined using the linear equation Y = 27 + 18X, where 27 is the one-time joining fee, and 18X is the cost of using the gym for X months.
Explanation:To determine the total cost Y in dollars of joining the gym and using it for X months, you would need to consider both the one-time joining fee and the recurring monthly cost. The one-time joining fee is $27 and the monthly cost is $18.
So, if you are going to gym for X months, the total cost will be the sum of the initial joining fee and the monthly cost times the number of months you are going. This relationship can be represented by a linear equation:Y = 27 + 18X.
In this equation, Y represents the total cost of joining and using the gym for X months. The 27 is the one-time joining fee and the 18X represents the total cost of the monthly fees for X months.

The heart rates for puppies are normally distributed, with a mean heart rate of 180 beats

bpm (beats per minute).
a. What percentage of puppies will have heart rates of less than 187 bpm?
b. What percentage of puppies will have heart rates between 170 bpm and 187 bpm?
c. If 500 puppies are examined, how many would you expect to have a heart rate of less
than 187 bpm?
d. 10% of all puppies will have a heart rate greater than what value?
Answers
a. The % less than 187 are all, including and less than, +1s. So 50% + 34.1% (1s) = 84.1% of the puppies
b. The % between 170 and 187 would be between -1.5s and +1s. So (34.1% × 2) + (13.6/2) = 68.2% + 6.8% = 75% of the puppies
c. Since in a) we said that the % for less than 187 bpm was 84.1%, we just take that % of 500: .841×500 = 420.5, so we'd expect between 420 and 421 puppies
d. 10% of all.puppies will have a heart rate greater than? This is asking what deviation above the mean corresponds to 10%.

1) Latricia randomly selected 25% of the seventh-grade students in her school and asked them their favorite season. Of the students surveyed, 51 chose summer as their favorite season. Based on the data, what is the most reasonable prediction of the number of seventh-grade students in her school who would choose summer as their favorite season?
a) 15
b)75
c) 150
d)200
Answers
Final answer:
The correct option is (d) 200. By using a proportion based on the sample data where 51 students (25% of the grade) chose summer, it can be predicted that approximately 204 students in total would choose summer. The closest provided option to this calculated number is 200.
Explanation:
Latricia surveyed 25% of the seventh-grade students, and out of this sample, 51 students chose summer as their favorite season. To find the total number who would choose summer, we assume that the sample is representative of the entire grade. If 51 represent 25%, then to find 100% (the whole grade), we use the following proportion:
Sample size (25%) : Number who chose summer in sample (51) = 100% : Total number who would choose summer
To solve the proportion for the total number who would choose summer, we set up a simple equation:
25% / 51 = 100% / x, where x is the total number we want to find.
To find x, we multiply both sides by x and divide by 25%:
x = (51 * 100%) / 25%
x = (51 * 4)
x = 204
Therefore, the most reasonable prediction for the number of seventh-grade students who would choose summer as their favorite season is 204. However, since 204 is not one of the options provided, we will choose the closest option, which is (d) 200.
