Doors for the small cabinets are 13.5 inches long. Doors for the large cabinets are 2.5 times as long as the doors for the small cabinets. How many large doors can be cut from a board that is 10 feet long?
Answers
Answer:
make 3
Step-by-step explanation:
13.5x2.5=33.75in
33.75in=2.8125ft
2.9ft(or so)x3=8.7
You can only make 3 with about 1.5 ft left over. cause 33.75x3=101.25, which is 8.4375ft, or 8.5 ft.

Sound Energy
Some ways that sound can be described are by loudness (or intensity) and by pitch. We can relate to loudness, because we often use the volume for our televisions or iPods™ to make the sound louder (more intense) or quieter (less intense). Pitch is a description of how high or low a sound is. Some sounds have a high pitch, like a chirping bird, while some have a low pitch, like a growling dog.
According to the article how is sound energy created?
Answers
Answer:
Sound energy is produced when a force causes an object or substance to vibrate. The energy is then transferred through the substance in waves, called sound waves.

0.73
Step-by-step explanation:
A rational number is any kind of decimal, fraction, or negative number, or whole number. This is a decimal, so you can go from in-between 0.71-0.79, any of those numbers will work.
A rational number is a number that is expressed as the ratio of two integers,3/4 is the rational number between 0.7 and 0.8.
What are Rational Numbers?'A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero
The given two rational numbers are 7/10 and 8/10 because
0.7 = 7/10 = 70/100 and 0.8 = 8/10 = 80/100
So any proper fraction between 70/100 and 80/100
Let us consider 75/100 = 3/4
Squaring 3/4 we get 3/4×3/4 = 9/16
So 0.7 <sqrt(9/16) < 0.8
0.7 <0.75 < 0.8
Hence 3/4 is the rational number between 0.7 and 0.8.

A city is putting in a sand pit at the park. The length is an even, one-digit whole number, and
the width is 6.7 feet. Which explains the least and greatest possible areas for the sand pit?
A.
The least and greatest one-digit whole numbers are 1 and 9. Since 1 × 6.7 = 6.7 and
9 × 6.7 = 60.3, the least and greatest areas for the sand pit are 6.7 square feet and
60.3 square feet.
B.
The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 12.7
and 8 × 6.7 = 48.7, the least and greatest areas for the sand pit are 12.7 square feet
and 48.7 square feet.
C.
The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 13.4
and 8 × 6.7 = 53.6, the least and greatest areas for the sand pit are 13.4 square feet
and 53.6 square feet.
D.
The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 14
and 8 × 6.7 = 56, the least and greatest areas for the sand pit are 14 square feet
and 56 square feet.
Answers
Answer:
Listen the number is an even one-digit, so that means all odd numbers that are one-digit numbers are out so that means number A is wrong so its between B, C, and D. If you read the answer thoroughly through B, C, and D you will find one of the 2 x 6.7 is wrong. To find the correct answer to 2 x 6 and if the sum of 2 x 6 is equal to your 2 x 6 you have the correct answer! Btw I forgot the exact answer but I know it was either B or C.
The correct option is The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 13.4 and 8 × 6.7 = 53.6, the least and greatest areas for the sand pit are 13.4 square feet and 53.6 square feet.
What is Area of rectangle?The area of rectangle is the product of its length to its width.
i.e., Area of rectangle= length x width
Given:
The length is an even, one-digit whole number, and the width is 6.7 feet.
So, the least one digit even number is 2
then , the least area is = 2 x 6.7
= 13.4
and, the greatest one digit even number is 8
then , the greatest area is = 8 x 6.7
= 53.6
Hence, The least and greatest even, one-digit whole numbers are 2 and 8. Since 2 × 6.7 = 13.4 and 8 × 6.7 = 53.6, the least and greatest areas for the sand pit are 13.4 square feet and 53.6 square feet.
