Answer:
21 box of books can be brought up by the delivery person at one time
Step-by-step explanation:
Here, we want to know the number of box of books that the delivery person could bring up at one time.
Let the number of boxes be x , so the total mass of the boxes that could come up at a time will be x * 40 = 40x lb
Let’s add this to the mass of the delivery person = 150 lb
So the total mass going inside the lift would be 150 + 40x
So we have to equate this to the maximum capacity of the lift;
150 + 40x = 1020
40x = 1020 - 150
40x = 870
x = 870/40
x = 21.75
Now since we cannot have fractional boxes, the number of boxes that could come into the lift without exceeding the maximum capacity of the lift is 21
The square root of 21 is a decimal or 3 square roots of 3

Answer:
C. Four less than the product of two and a number is less than the product of four and the same number increased by eight.
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Converting expressions to word form
Step-by-step explanation:
<u>Step 1: Define</u>
2x - 4 < 4x + 8
<u>Step 2: Translate</u>
"2x" is the product of two and a number <em>x</em>
" - 4" is four less
"<" is less than
"4x" is the product of four and a number <em>x</em>
" + 8" is increased by 8
<u>Step 3: Combine</u>
The difference between the product of two and a number <em>x</em> and 4 is less than the sum of the product of four and a number <em>x</em> and 8.
<u>Step 4: Reword</u>
Four less than the product of two and a number is less than the product of four and the same number increased by eight.
Answer:
1. 4/12 , 6/8
2. 16/12 , 3/4*
3. 3/2 , 15/14
4. 10/16 , 5/8
10/16 = 5/8
Which ratio forms a proportion with 9/15?
1. 6/10
2. 16/21
3. 36/50
4. 45/70
9/15 = 3/5 which is 6/10
A textbook weighs 2.5 pounds. How many kilograms does the textbook weighs? Round your answer to the nearest tenth of a pound. 1 kg = 2.2 lb
1. 1.1 kg
2. 1.8 kg
3. 5.5 kg
4. 4.7 kg
2.5 lbs * (1 kg/2.2 lbs) =
Solve the proportion using number sense. 2/8 = x/ 48
1. 6
2. 12
3. 16
4. 8
8 * 6 = 48
so what is 2 times 6 ?
or another way
1/4 * 48 = 12
Solve the proportion using cross products. 18/20 = k/110
1. 99
2. 122
3. 3.3
4. 2.9
20 k = 18*110
2 k = 18 *11
k = 9 * 11
Are the ratios 8/12 and 10/25 proportional? Explain
8/12 = 2/3
10/15 = 2/3 so no way 10/25 is 2/3
