Answer: She read for 10 Days, equation below

Step-by-step explanation:

Number of pages = 180

Rate = 12pages Per day

Number of days read = (180-60) /12

Days read = (total no of page - page left)/page read per day

= 120/ 12 = 10 days

Days remaining = pages left /page per day

=60/ 12 = 5

Step-by-step explanation:

A coefficent is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. Or in other words, the number being multiplied with the variable. For example, the 4 in 4x.

The expression is -3x + 1. If we go back to the definition, the coefficient is the number combined with the variable.

So the answer is -3.

Answer:

Step-by-step explanation:

Cone

Givens

r = 1.5 inches

h = 4 inches

Formula

V = 1/3 pi r^2 h

V = 1/3 3.14 * 1.5^2 * 4

V = 1/3* 3.14 * 2.25 * 4

V = 9.42

Semi sphere

Givens

r = 1.5

Formula

V = 2/3 * pi * r^3

Solution

V = 2/3 * 3.14 * 1.^3

V = 7.065

Total

V = 9.42 + 7.065

V = 16.485

Rounded to the nearest 1/100

V = 16.49
