Answer:
C) The total number of about uniforms needed is 60 x 80 uniforms.
Step-by-step explanation:
The Number of total stores the owner has = 64 stores
The number of employees uniform needed in 1 store = 79 uniforms
Now, 64 is Rounded off to about 60.
and 79 is Rounded off to about 80.
⇒ The total number of uniforms in 60 stores = 60 x ( uniform in 1 store)
= 60 x (80 uniforms)
or, the expression of total uniforms needed = 60 x (80 uniforms)
Hence, the total number of about uniforms needed is 60 x 80 uniforms.
Answer: 40 bags
Step-by-step explanation:
Given: The dimension of farmers pasture is 1000 feet by 200 feet.
The area of pasture= 
Since, area covered by 1 bag of fertilizer= 5000 square feet
Therefore, the amount of fertilizer required for 1 square feet of area= 
The amount of fertilizer required for 5000 square feet of area= 
Therefore, the amount of fertilizer required for 5000 square feet of area= 40 bags

Answer:
26/3 or 8.66666 (8.6 with a line over the 6)
Step-by-step explanation:
According to the problem, 13/2 pounds is only 3/4 of a quart. A unit rate, however, has a denominator value of 1. To solve this question, we must change the value of 3/4 to 1.
The first step to this is changing 3/4 to 1/4. This means affecting the value 13/2 pounds. 1/4 is a third of 3/4. We must find a third of 13/2 to properly change this relationship. So, we should do 13/2 ÷ 3. This can also be written as 13/2*3. So, a third of 13/2 is 13/6. Our new relationship is 13/6 pounds = 1/4 quart.
Now, we can multiply 13/6 and 1/4 by 4 to get ? and 4/4, or 1. We can multiply the numerator by 4 to finish this step. 13/6 becomes 13*4/6, which equals 52/6. 52/6 can be divided by 2 to simplify the fraction and becomes 26/3.
So, the <em>unit rate of 13/2 pounds per 3/4 quart is 26/3</em>. 26/3 can also be written as 8.66666, or 8.6 with a line over the 6, in decimal form.
