PLZ HELP I MAKE YOU BRAINILY!!!!!
Answer:
755.3
Step-by-step explanation:
The cylinder volume formula is pi*r^2*height. The r symbolizes the radius, which is 4. The height is 5. Thus, the volume of the cylinder is 5*16*pi = 80pi.
The rectangle's volume is length*width*height. The length is 6, the width is 14, and the height is 6. Therefore, the volume is 6*6*14, which is 504 in.
Now all you have to do is add the two volumes together. 80pi is around 251.3, so 251.3 + 504 = 755.3.
Answer:
I think the answer is B: 755.3^3.
Step-by-step explanation:
Don't hate me if I'm wrong please!!!
To find the volume of multiple figures, just find the volume of each of them and add them together.
Volume of rectangular prism: V = lwh; 14 * 6 * 6 = 504
Volume of cylinder: V = pi * r^2 * h; 16 * 3.14 * 5 = 251.2
504 + 251.2 = 755.2
Since this is the closest answer, the answer is B: 755.3^3.

Hannah ordered books for her son from an online retailer. Each book costs $7.25 and there is a shipping fee of $6.75 for the entire order.
(a)
Part A
What is the cost of Hannah's order if she buys 9 books?
$
Part B
Write a sentence to describe how you calculate the cost of Hannah's order.
Answer:
Part A:
1 book -- $7.25
9 books -- (9 * 7.25) = $65.25
And shipping fee -- (65.25 + 6.75) = $ 72
Part B
9 multiplied by the cost and added with the shipping fee to get Hannah's total cost.

Which value of x is the solution to the equation 4(-3x+8)= -16?
answer choices:
1. -4
2. -2
3. 2
4. 4
explain
Answer:
x = 4
Step-by-step explanation:
4(-3x + 8) = -16
Divide both sides by 4
-3x + 8 = -4
Subtract 8 from both sides
-3x = -12
Divide both sides by -3
x = 4
what is the area in square centimeters, of the trapezoid below?
Answer:
Area of the trapezoid = 82.24 cm²
Step-by-step explanation:
Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Here, [tex]b_1[/tex] and [tex]b_2[/tex] = Bases of the trapezoid
[tex]h[/tex] = Vertical distance between the parallel sides
Length of bases [tex]b_1=6.7[/tex] cm
[tex]b_2=12.5+6.5[/tex] = [tex]19[/tex] cm
[tex]h=6.4[/tex] cm
Area of the given trapezoid = [tex]\frac{1}{2}(6.7+19)\times 6.4[/tex]
= [tex]82.24[/tex] cm²

BEST ANSWER GET BRANLIEST
Answer:
0 ≤ x ≤ 2 (i assumed that the arrows included 0 and 2).
Step-by-step explanation:
One arrow shows 0 and greater (as it is pointing right) and the other shows 2 and smaller (as it is pointing left). The arrow pointing right has the equation of:
x ≥ 0 (where x is a random number)
The arrow pointing left has the equation of:
x ≤ 2 (where x is a random number)
Assuming that you need to find an equation so that x fits both inequalities, we combine them into one inequality and get:
0 ≤ x ≤ 2

The perimeter of a square is 54 cm.Find the length of a diagonal, rounding to the nearest tenth
Answer:
19.09 = 19.1
Step-by-step explanation:
we can split the square into two right triangles. Becasue the perimeter of the square is 54cm, we know the each side is 13.5 cm (54cm / 4). Using the pythagoras theorem, the diagonal is 19.1 cm.

Jose is baking cakes. He needs 3/4 of butter for each cake. One stick of butter is a 1/2 of a cup. How many sticks do he need to bake 8 cakes?
Answer: 6 sticks
Step-by-step explanation:
Given
Joe needs [tex]\frac{3}{4}[/tex] butter for each cake
One stick of butter is equivalent to 0.5 cup
So, joe need
[tex]\dfrac{3}{4}\times \dfrac{1}{2}=\dfrac{3}{8}\ \text{cup}[/tex]
for each cake
To bake 8 cakes, it is
[tex]\Rightarrow \dfrac{3}{4}\times 8=6\ \text{sticks}[/tex]

Johann borrows money from his parents to purchase a bike. He makes weekly payments to his parents to repay the money
borrowed. The total amount of money repaid at the end of week n can be represented using the recursive formula a, = 10+ an-1-
At the end of the fourth week, Johann had repaid his parents a total of $55. What is the total amount Johann had repaid his
parents at the end of the first week?
o $10
$20
$25
$35
Answer:
$25
Step-by-step explanation:
An = 10 + An-1
At the end of 4th week ; amount repaid = $55
A4 = 10 +
An = a + (n - 1)d
n = 4
A4 = 10 + (4 - 1)d
55 = 10 + 3d
55 - 10 = 3d
45 = 3d
d = 15
Hence, at the end of first week :
A1 = a + d
$10 + $15
= $25
