Sheila has 12 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 2 1/4 pounds
NeX [460]

Answer:

6 containers needed

Step-by-step explanation:

Given

Total = 12\frac{1}{2}\ lb ----- Size

Container = 2\frac{1}{4}\ lb ----- Size

Required

Determine the number of containers needed

This question illustrates the knowledge of fraction and division.

To get the number of containers needed, we simply divide the total size by the size of the container as follows;

Number = Total/Container

Number = 12\frac{1}{2}/2\frac{1}{4}

Convert to improper fractions

Number = \frac{25}{2}/\frac{9}{4}

Number = \frac{25}{2}*\frac{4}{9}

Number = \frac{100}{18}

Number = 5.5555556

Number = 6 --- Approximated

Andrew [12]

Answer:

1.75 gallons of paint

Step-by-step explanation:

A student in the construction trades program has 4 1/2 gallons of paint

If the student uses 2.75 gallons in one room then the gallons of paint that are left can be calculated as follows

= 4 1/2 - 2.75

= 9/2 - 2.75

= 4.5 - 2.75

= 1.75

Hence 1.75 gallons of paint are left

Laura will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $55.98 and costs an
Yuliya22 [10]

Answer: it would take 280 miles before Laura pays the same amount for both plans..

Step-by-step explanation:

Let x represent the number of miles that Laura drives using either the first plan or the second plan

Let y represent the total cost of x miles when using the first plan

Let y represent the total cost of x miles when using the second plan

The first plan has an initial fee of $55.98 and costs an additional $0.13 per mile driven. This means that the total cost of x miles would be

y = 0.13x + 55.98

The second plan has an initial fee of $69.98 and costs an additional $0.08 per mile driven.This means that the total cost of x miles would be

z = 0.08x + 69.98

To determine the number of miles that Laura would drive before the amount for both plans becomes the same, we would equate y to z. It becomes

0.13x + 55.98 = 0.08x + 69.98

0.13x - 0.08x = 69.98 - 55.98

0.05x = 14

x = 280
