Answer:
20 lol
Step-by-step explanation:
Idk brooks srry, i would try asking google or something
9 inches long
9 divided by 10 is .9
multiply it by 10 (to get the length of the purple ribbon) and the answer is 9
Answer:
See explanation
Step-by-step explanation:
The constant of variation is found using the slope formula:
![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
The given relation is
X : -2 , -3, -4, -5
Y : -5, -7.5,-10,-12.5
We can use any two ordered pair to find the constant of variation.
Using (-2,-5) and (-3,-7.5), we have
![m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-7.5--5%7D%7B-3--2%7D%20%3D%5Cfrac%7B-2.5%7D%7B-1%7D%20%3D2.5)
The constant of variation is 2.5
We need to repeat this for all the options to identify the one with -2.5 as slope.
unfortunately, you did not provide the remaining options.
Answer:
b=4
Step-by-step explanation:
A = 1/2 b*h
24 = 1/2 b* (3b)
combine like terms
24 = 1/2 *3 * b^2
24 = 3/2 b^2
multiply by 2/3 on each side
24 * 2/3 = 2/3 * 3/2 * b^2
16 = b^2
take the square root of each side
±sqrt(16) = sqrt(b)
±4 =b
but since b is a length it can only be positive
4 =b
