1. 4^2 +x^2 = 6^2
16 + x^2 = 36
x^2 = 20, x = sqrt(20) = 4.47 miles
2. using the same equation as above: 20 inches
3. needs to be a right triangle so A
4. using distance formula answer is 7.07 units
5.volume cylinder: 62.82, volume sphere: 33.51, difference:=62.82 -33.51 = 29.31 cubic inches

Answer:
Part 9) The number of items on Emily's grocery list is 5 and the number of items on Bobby's grocery list is 13
Part 10) The height of the taller bookshelf is 4 feet and the height of the shorter bookshelf is 1 foot
Step-by-step explanation:
Part 9)
Let
x ----> number of items on Emily's grocery list
x ----> number of items on Bobby's grocery list
we know that
----> equation A
----> equation B
Solve by substitution
Substitute equation A in equation B

solve for x



Find the value of y

therefore
The number of items on Emily's grocery list is 5 and the number of items on Bobby's grocery list is 13
Part 10)
Let
x ----> the height of the taller bookshelf in feet
y ----> the height of the shorter bookshelf in feet
we have
----> equation A
Remember that

To convert inches to feet divide by 12
so

----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x

therefore
The height of the taller bookshelf is 4 feet and the height of the shorter bookshelf is 1 foot
Answer:
A =28.26
Step-by-step explanation:
Using the area formula
A = pi r^2
We use pi = 3.14 and the radius is 3
A = 3.14 * (3)^2
A = 3.14 *9
A =28.26
