The volume of a cube is 8 in^3 What is the length of one side?
2.7in3
2 in3
2.7 in
2 in
Answer:
2 in
Step-by-step explanation:
Use the cube volume formula, V = s³, where s is the side length
Plug in 8 as V and solve for s:
V = s³
8 = s³
Take the cube root of both sides:
2 = s
So, the length of one side is 2 inches.
The length of one side of cube will be 2 in i.e. option D.
What is volume ?Volume is the amount of space that something contains or fills.
Volume of the cube = side³ = a³
We have,
Volume of the cube = 8 in³
And,
Side of cube = a
So,
Volume of the cube = side³ = a³
i.e.
8 = a³
⇒ a³ = 8
a = ∛8
On solving we get,
a = 2
i.e.
Side of cube = 2 in
Hence, we can say that the length of one side of cube will be 2 in i.e. option D.

A car moving on a highway covers the first 400.0 m in 18.0s and then covers the next 250.0 m in 24.0 s.
What is the average speed of the car?
Answer: 15.48 m/s
Step-by-step explanation:
The following information can be gotten from the question:
Total distance covered by the car will be:
= 400m + 250m
= 650m
Total time taken = 18.0s + 24.0s = 42s
Average speed = Distance/Time
= 650/42
= 15.48 m/s

Answer:
130z-3
Step-by-step explanation:
Break down the equation:
(9[tex]z^{2}[/tex]-4)=
9z * 9z= 81z
You can't subtract 4, so I left it at (81z- 4)
(7[tex]z^{2}[/tex]+ 1)=
7z * 7z= 49z
You can't add 1, so I left it at (49z+ 1)
Then Solve:
You can add 81z and 49z.
81z+49z= 130z
-4+1= -3

Previous 20 Item 20 The width of a rectangular room is 60% of its length. The length of the room is 10 feet. What is the area of the room
Answer: 60 feet²
Step-by-step explanation:
The width of the rectangular room is 60% of the length which is 10 feet.
The width is therefore:
= 60% * 10
= 6 feet
The area of a rectangle is calculated by the formula:
= Length * Width
Area there is:
= 10 * 6
= 60 feet²
A plumber chargers a fee of $75 plus $30 per hour on the job. Make a table of values for the total charge depending on the number of hours the plumber works. Determine if this can be defined by a linear or an exponential function. What is the function?
a. Linear: T=30+75h
b. Exponential: T=75(30)^h
c. Exponential: T=30(75)^h
d. Linear: T=75+30h
Answer:
d
Step-by-step explanation:
It is going at a steady rate of 30$ an hour
Total charges of the plumber depending on the number of hours he works is defined by the linear function T = 75 + 30h.

A map has the scale 1cm:40mi. What is the distance between two towns that are 3.3cm apart on the map?
Answer:
132 miles
Step-by-step explanation:
Given data
scale 1cm:40mi.
this means that
1 cm on the map is equal to 40 miles on
Hence if 1cm rep 40 miles
3.3cm will rep x
cross multiply
x= 3.3*40
x=132 miles

9. A triangle has an area of 36 yd2 and a base of 3 yd, what is the height of the triangle?
Answer:
24yards
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 24 \ yards}}[/tex]
Step-by-step explanation:
The formula for a triangle's area is:
[tex]a= \frac{1}{2} bh[/tex]
We know the area is 36 square yards and the base is 3 yards.
[tex]a= 36 \ yd^2 \\b= 3 \ yd[/tex]
Substitute the values into the formula.
[tex]36 \ yd^2 = \frac{1}{2} (3 \ yd )h[/tex]
Divide by 1/2 or multiply both sides by 2.
[tex]2 * 36 \ yd^2 = \frac{1}{2} (3 \ yd )h *2[/tex]
[tex]72 \ yd^2= (3 \ yd)h[/tex]
We are trying to solve for the height, so we must isolate that variable. h is being multiplied by 3. The inverse of multiplication is division, so we must divide both sides by 3 yd.
[tex]\frac {72 \ yd^2}{3 \ yd}= \frac{(3 yd) h}{3 \ yd}[/tex]
[tex]24 \ yd =h[/tex]
The height of the triangle is 24 yards.

A city has 17391 registered Democrats and 20553 registered
Republicans. An organization wishes to survey equal proportions of
each group.
The council decides to survey 13 Republicans
How many Democrats should they survey? Democrats
Answer: The council should survey 11 Democrats.
Step-by-step explanation:
A proportional relationship is written as:
y = k*x
Where k is the constant of proportionality. y is the number of surveyed members, and x is the total number of registered members.
If we use the same proportion for each case, then we will use the same value of k.
We know that there are 20553 registered Republicans, and the council decides to survey 13 of them, then we will have the relation:
13 = k*20553
Now we can solve this for k:
13/20553 = k
Then the proportional relationship will be:
y = (13/20553)*x
The number of democrats they should survey can be found if we replace x by the number of registered Democrats, then we use x = 17391
this leads to:
y = (13/20553)*17391 = 11
The company should survey 11 Democrats.
