Write an inequality showing the amount money each club should raise to meet the minimum target. Use f for the amount of money that each club raises.
Answers
Answer:
600=10f+200
Step-by-step explanation:
since $600 is the target, and the faculty already donated 200 dollars 200 would be the y intercept. since f is the amount of money that the clubs should raise, we can set that as 10 f since there are 10 clubs and since it needs to be inequality, it would be written in the y = mx + b format. hope this helps!

He asked if anyone could figure out the area of the shaded half of the baseball field. Help Lucy figure out the answer by using the drawing below. please explain how you got your answer!
Answers
Step-by-step explanation:
Area is Base x Height right?
so, the base of the triangle would be 90 ft and the height would be 90 ft!
So 90 x 90 = 8,100 ft!!
This is how I think, so it may be wrong, but this is how I do it!
answer:
a=1/2×b×h
a=1/2x90×90
a=45×90
a=4,050 ft.
in simpler terms....
90×90=8100
this is the area of the ENTIRE FIELD so to find half divide by two 8100÷2=4,050.
4,050 ft.

Irene wants to use equivalent ratios to solve 3,712÷64, but she can't remember how. Show Irene what to do.
Answers
Answer:3,712÷64=58
Step-by-step explanation:
Answer: The ratio is 58:1, and the division is = 58. Scroll for solving, check, and notes.
Explanation:What we know:
The question wants us to use equivalent ratiosThe numbers 3,712 and 64 have common denominatorsAn equivalent ratio is a ratio that is something of a simplified form of large numbers, written in a fraction, with a colon, or with the word 'to'How to solve:
We need to find the equivalent ratio of 3,712 and 64, and then solve the question based on that.
Process:Finding equivalent ratios
Set up equation 3712/64
Rewrite into colon-ratio form 3712:64
Divide by common denominator /64 /64*
Solution: =58:1
*Read bottom of notes to find out how I found this denominator
Answer: The ratio is 58:1; the solution to the division is 58.Notes:
There is no way to always know the ratio's common denominator. However, there are some general rules of thumb that may help:
-All numbers have a common denominator of 1. Sometimes, that's the most simplified form.
-All even numbers (Those that end in {0, 2, 4, 6, or 8}) have a common denominator of 2
-All numbers whose digits add up to {3, 6, or 9} (such as 12: 1+2 = 3) have a common denominator of 3.
-These three numbers serve as basic building blocks. You can keep simplifying with them until you get to a prime number. Let's use our problem as an example:
3712 and 64 - both are even, simplify by 2
1856 and 32 - both are even, simplify by 2
928 and 16 - both are even, simplify by 2
464 and 8 - both are even, simplify by 2
232 and 4 - both are even, simplify by 2
116 and 2 - both are even, simplify by 2
58 and 1 - there is a prime number, so this is the simplest form.
Now we take all of our simplifications: 2^6. 2^6 = 64, so the common denominator is 64.
Check:
Our ratio, 58:1, is the simplified form of 3,712 div. 64. This is seen better by rewriting both into a fraction-ratio form:
58:1 3712 div. 64
58/1 3712/64
Luckily, our ratio has a 1 in it. This means that when we multiply the ratio by 64 (what the 1 represents), it should yield the original equation.
3712/64 = 58/1
3712/64 = (58/1)*64
3712/64 = 3712/64
Therefore, 58:1 is the correct ratio.

Answers
Answer:
a. the first and last one
b. the second and third one
Step-by-step explanation:
a. 11x-3x-10x=18x, so the first one is definitely the answer. If you look at the last one, you can see that 10x+8x also equals 18x. The other options do not equal 18x, so those can be eliminated.
b. If you distribute the 3 outside of the parentheses, you can see that the expression 3(1+3y) equals 3+9y (because 3*1=3 and 3*3y=9y). So, the third one can be determined to be one of the answers. We can see that the second one also simplifies to be 3+9y, so this one can also be determined to be the answer. The other ones can be eliminated because they do not equal 3+9y.
Hope this helped! :)
Answer:
a) 18x and 8x + 10x
b) 3 × 1 + 3 × 3y and 3 + 9y
Step-by-step explanation:
11x - 3x = 8x and then 8x + 10x is left. The answers are 18x and 8x + 10x.
3 × 1 is 3 and 3y × 3 is 9y.
The net of a square pyramid and its dimensions are shown in the diagram. What is the total surface area in square feet?
1,120 ft^2
5,760 ft^2
1040 ft^2
976 ft^2
Answers
Answer:
c
Step-by-step explanation:
The surface area of the square pyramid is 1040 ft² in the given figure.
What is the total surface area of the pyramid?The total surface area of the given pyramid can be expressed as:
Surface area of a square pyramid = A + (1/2) p × s
where A is the base area, p is the perimeter of the base, and s is the slant height
As per the question, we have
length (l) = 20 ft
base perimeter (p) = 4l = 4 × 20 = 80 ft
base area (A) = l² = 20² = 400 ft²
slant height (s) = 16 ft
Substitute the values in the formula for surface area:
Surface area = 400 + 1/2 × 80 × 16
Surface area = 400 + 1280/2
Surface area = 400 + 640
Surface area = 1040 ft²
Thus, the surface area of the square pyramid is 1040 ft².
