<span>Each smaller donation was for $20
The largest donation was $15 greater than the smaller donation.
First, determine the size of each donation. Since they are in a ratio of 4:4:7, it's easiest to add the ratios together (4+4+7) = 15. Then divide the total donation by that sum (75/15) = 5. Finally, multiply 5 by each of the ratios.
5 * 4 = 20, 5 * 4 = 20, and 5 * 7 = 35
So the 2 smaller donations were $20 each, and the largest donation was for $35.
The largest donation was $35 - $20 = $15 larger than one of the smaller donations.</span>
Answer: f(x)=10+2x
Step-by-step explanation: x = the number of years. 10 represents the starting length . please tell me if i was right
A single stepping stone as you have said is 20 inches sqaure. This means that it has an area of 20.
All you would need to do then is multiply 20 by 30 to get the area of thirty tiles. The result of this would be 600.
If you mean one side of the stepping stone is 20 inches then you would multiply 20 by 20 to get the area of one, since that would be multiplying length times width (the area formula). The area of one would result in 400 and you would then multiply this by the thirty tiles (400 times 30) to get 12000.
Answer:
-y^2 - 10 y - x^72 + -1
Step-by-step explanation:
Simplify the following:
-y^2 - 3 y - 5 - (x^36)^2 - 7 y + 4
Multiply exponents. (x^36)^2 = x^(36×2):
-y^2 - 3 y - 5 - x^(36×2) - 7 y + 4
36×2 = 72:
-y^2 - 3 y - 5 - x^72 - 7 y + 4
Grouping like terms, -y^2 - 3 y - 5 - x^72 - 7 y + 4 = -y^2 + (-3 y - 7 y) - x^72 + (4 - 5):
-y^2 + (-3 y - 7 y) - x^72 + (4 - 5)
-3 y - 7 y = -10 y:
-y^2 + -10 y - x^72 + (4 - 5)
4 - 5 = -1:
Answer: -y^2 - 10 y - x^72 + -1
Decimal Form:
0.92387953
