Answer:
Step-by-step explanation:
The area is the product of the length and width
- The area = 7 1/6 m² = 43/6 m²
- The length = 3 1/3 m = 10/3 m
Width = ?
- A = lw
- w = A/l
- w = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 m
The width is 2 3/20 m
Answer:
16
Step-by-step explanation:
Let the 1st part of your answer be x
, so the 2nd part will be 40-x
. From the given information, we can write the equation: (1/4)x = (3/8) × (40-x)
. We can simplify this into (1/4)x = (120-3x)/8
; 8x = 480-12x
; 8x+12x = 480
; 20x = 480
; x = 480/20; x = 24
Therefore, the 1st part = 24
Plug this into your 40-x equation to get: 40 - 24 = 16
247.62 x 0.15 = 37.143
round to $37.14
I hope that helped :)
Step-by-step explanation:
f(x) = 3x² - 2x + 7
f(-2) = 3(-2)² -2(-2) + 7
= 3(4) + 4 + 7
= 23
