Question

1. mark loads a crate that weighs 22.5 pounds and 12 boxes that each weigh 11.25 pounds onto a truck. what is the total weight of the crate and the boxes? a 135 pounds b 157.5 pounds c 270 pounds d 281.25 pounds 10 apply math models water evaporates at a rate of 1.5 ounces per day from a container that holds 34 ounces when full. which expression represents the amount of water remaining in the container after d days? a 1.5 + 34d b 34 + 1.5d c 34 - 1.5d d 32.5d

Explanation:

Problem 9

Step1: Calculate total weight of boxes

Each box weighs 11.25 pounds, and there are 12 boxes. So total weight of boxes is \( 12 \times 11.25 \) pounds.
\( 12 \times 11.25 = 135 \)

Step2: Add weight of crate

Crate weighs 22.5 pounds. Total weight = weight of boxes + weight of crate = \( 135 + 22.5 \)
\( 135 + 22.5 = 157.5 \)

The initial amount of water is 34 ounces. Water evaporates at 1.5 ounces per day, so after \( d \) days, the amount evaporated is \( 1.5d \) ounces. To find the remaining water, we subtract the evaporated amount from the initial amount, so the expression is \( 34 - 1.5d \).

Answer:

B. 157.5 pounds
