Answer:
a. x = total - $5
b. x = $6
c. x = $10
Step-by-step explanation:
a. pen + book = total
Let x = book
$5 + x = total
x = total - $5
b. pen + book = total
Total = 411
$5 + x = $11
x = $11 - $5
x = $6
c. pen + book = total
Total = $15
$5 + x = $15
x = $15 - $5
x = $10
Solve the following: $10 = $7.03(1.03)^t for t.
log 10 - log 7.03 = tlog 1.03. Solve for t.
1 - 0.847
---------------- = t = 11.77 years (answer)
0.013
When a line is perpendicular, the slope is the negative reciprocal. Therefore, since the slope is 4, the slope of a line perpendicular is -1/4

Area of the sector is 4.71 sq units
Step-by-step explanation:
- Step 1: Area of the sector = Area of the circle × (C/360) where C is the central angle.
Area of the sector = πr²(C/360) = 9π × 60/360
= 9 × 3.14 × 1/6
= 28.26/6 = 4.71 sq units
