The mass of the rock in kg is 90,000 kg
Answer is (A) because it is concave and it has 8 sides
Answer. Option B. 0.8 cents.
Solution:
With a 5-pound box of detergent will wash 20 loads of laundry, then with a 15-pound box (5*3) of detergent will wash 20*3=60 loads of laundry, and you would pay $10.00.
To wash 60 loads of laundry with 5-pound box, you would need three 5-pound box, and you would pay $3.50*3=$10.50.
Then you would save in total $10.50-$10.00=$0.50
And per load, you would save: $0.50/60=$0.008=0.008*100 cents=0.8 cents
Answer:
171.2
Step-by-step explanation:
7% x 160 = 11.2
11.2 + 160 = 171.2
First, let's see how 23 compares with the squares of the positive whole numbers on the number line.
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
The value of 23 is right between the square of 4 and the square of 5. Thus, the value √23 will be between 4 and 5.
Since 23 is much, much closer to the square of 5 than the square of 4, we can assume that the value √23 will be closer to 5 on the number line than 4.
Look at the attached image to see where I plotted the approximate location of √23.
You will realize that this approximation is pretty close since the actual value is roughly 4.80.
