Answer:
Please find the answer in the explanation.
Step-by-step explanation:
Given that Each toy box is in the shape of a cube. The total volume of the five toy boxes when placed in a row is 2,600 cubic inches.
If Claire thinks she will need about 40 inches of floor length for the toy boxes and Lucy thinks she will need about 45 inches of floor length for the toy boxes, one of them must be right.
Since Volume = L × B × h
Substitute the volume value and the length into the formula to know the area of the box. This must be in whole number and not in decimal number.
Area = 2600 / 40
Area = 65 square inches. For Claire.
Then for Lucy, we get:
Area = 2600 / 45
Area = 57.7778 square inches
We can therefore conclude that Claire is correct.
Answer:
the slope of the line=0/6
Step-by-step explanation:
you can use the formula `y-y/`x-x, where (-8,5)=(x,y) and (-2,5)=(`x,`y)
5-5/-2--8
5-5/-2+8
0/6
Therefore, the slope of the line=0/6
Answer: 250 miles per inch

Answer:72 ounces
Step-by-step explanation:
The correct answer is 72 ounces. In order to reach this answer you need to multiply 80 times .9, which equals 72.
Answer:
6 and 8
Step-by-step explanation:
The hypotenuse of a 30°-60°-90° triangle measures 10 inches.
To find the length of one of the legs, we use the idea of Pythagorean Triples.
Pythagorean Triples are any set of three numbers that satisfies the Pythagorean Theorem. Some common examples are:
- 3, 4 and 5
- 5, 12 and 13
- 9, 40 and 41
Note that in a Pythagorean Triple,
- The longest length is always the Hypotenuse.
- New Triples can be formed from product of existing triples.
In our given triangle, the Hypotenuse=10 Inches
Consider the Pythagorean Triple 3,4, and 5
- 5 is the Hypotenuse
- Multiply the Triples by 2, we obtain:
- 6, 8 and 10 (in which 10 is the hypotenuse)
Therefore, 6 and 8 could be the length of a leg of the 30°-60°-90° triangle.
