A ringtoss toy is composed of a rectangular prism on top of a cylinder. The rectangular prism is completely filled with water. The dimensions of the rectangular prism are shown in the diagram.
What is the volume of the rectangular prism in cubic centimeters?
165 cm3
270 cm3
348 cm3
26 cm3
Answers
Answer:
270 cm3
Step-by-step explanation:
The volume of the given rectangular prism is 270 cm³.
What is Volume?Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.
Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.
We have
Length = 9 cm
Width = 2 cm
Height = 15 cm
Using the formula for volume of the rectangular prism
= length x width x height
= 9 x 2 x 15
= 270 cm³
Thus, the volume of the given rectangular prism is 270 cm³.

This graph shows the relationship between the number of cubic yards and total cost of topsoil at a garden shop.
Mulch
The equation, y=25x, represents
the cost, y, in dollars, of x cubic
yards of mulch at the garden shop.
Type an equation to represent the cost of the topsoil. Show your work.
and
How does the cost of the topsoil compare to the cost of the mulch?
Answers
Answer: y=30x
top soil is 5 more dollars than mulch
Step-by-step explanation:
to find y=30x
see what y equals when x equals 1
The cost of the topsoil is $5 more than the cost of the mulch.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, the equation, y=25x, represents the cost, y, in dollars, of x cubic yards of mulch at the garden shop.
From the, graph we have coordinates (1, 30) and (2, 60)
We know that, slope of points is (y2-y1)/(x2-x1)
Now, (60-30)/(2-1)
= 30
Substitute, m=30 and (x,y)=(1, 30) in y=mx+c, we get
30=30(1)+c
c=0
Substitute, m=30 and c=0 in y=mx+c, we get
y=30x
Per 1 cubic yard
Topsoil is y=30x=$30 and cost of the mulch is y=25x=$25
So, difference in cost is 30-25=5
Comparing cost in both the situation, the cost of the mulch is less than topsoil
Therefore, the cost of the topsoil is $5 more than the cost of the mulch.

A woodworker wants to cut a board that is 10.016 feet long into 4 equal-length pieces. How long will each of the cut boards be?
Answers
Answer:
2.504 feet
Step-by-step explanation:
Find the length by dividing 10.016 by 4
10.016/4
= 2.504
So, each cut board will be 2.504 feet
We have
[tex] \begin{cases} \sf No. \: of \: pieces = \frak{4} \\ \sf Total \: Length = \frak{10.016 \: ft} \end{cases} [/tex]
So,
Length of 1 board = 10.016/4
Length of 1 board = 2.504 ft
So,
The length of 1 board is 2.504 ft.

What is the solution to the equation 3 + 4 sqr root 4y = 4?
Answers
Answer:
1/64
Step-by-step explanation:
Given the expression
3+4√4y = 4
4√4y = 4-3
4√4y = 1
√4y = 1/4
Square both sides
(√4y)²= (1/4)²
4y = 1/16
y = 1/16 * 1/4
y = 1/64
Hence the value of y is 1/64
Use the information from the graphs to write the equation in y=ab*^x
Answers
Answer:
1). y = 4(1.75)ˣ
2). y = (2)ˣ
Step-by-step explanation:
1). Let the equation of the given exponential graph is,
y = a(b)ˣ
Graph of the given equation passes through two points (0, 4) and (0+1, 4+3)
For point (0, 4),
4 = a(b)⁰
a = 4
For point (1, 7),
7 = 4(b)¹
b = [tex]\frac{7}{4}[/tex]
b = 1.75
Therefore, equation of the function is,
y = 4(1.75)ˣ
2). Similarly, equation of the second graph will be same in the form of
y = a(b)ˣ
Second graph passes through the points (0, 1) and (2, 4)
For (0, 1),
1 = a(b)⁰
a = 1
For (2, 4),
4 = 1(b)²
b = 2
Therefore, exponential function representing the graph will be,
y = 1(2)ˣ
y = 2ˣ
