Answer:
3.68 inches × 77.28 inches
Step-by-step explanation:
Given that,
The perimeter of a rectangle is 162 inches.
Let the width is b.
ATQ,
Length = 7 times than 3 times the width
l = 7(3b) = 21b ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
Put all the values,
162 = 2(21b+b)
81 = 22b
b = 3.68 inches
Put the value of b in equation (1)
l = 21b
= 21 (3.68)
= 77.28 inches
Hence, the dimensions of the rectangle are 3.68 inches × 77.28 inches
Answer:
Step-by-step explanation:
Use the normcdf( function on a basic calculator as follows:
normcdf(-1000, 9750, 12000, 4500). Result: 0.307. This is the area under the standard normal curve to the left of 9750.
But we want the area under the standard normal curve to the right of 9750, so we subtract this 0.307 from 1.000, obtaining the desired result: 0.693. This roughly corresponds with the last of the given possible answers, 69.15%.
Answer:
Option 4 (equilateral)
Step-by-step explanation:

Answer:
64v
Step-by-step explanation:
2(5v+6)-6(-9v+2)
Distribute the 2 to everything in the parentheses.
10v+12-6(-9v+2)
Distribute the -6 to everything in the parentheses.
10v+12+54v-12
Combine like terms
64v
