Rondell covered a table top with 36 square tiles. Each tile measures 8 inches by 8 inches. What is the area of the table top?
Answer: 2,304 square inches
Step-by-step explanation:
if there are 36 total tiles on the table, that means there are 6 on each side.

A dump truck pours sand into a container in the shape of a rectangular prism with a square base of length 2 feet. The height, h, of the sand in the container increases at a rate of approximately 8 inches per minute. Create an equation that models the volume, V, of the sand in the container in terms of h, then use the equation to determine the time at which the volume is 64 cubic feet. Note that the volume of a rectangular prism is V=l×w×h, where l, w, and h are the length, width, and height of the prism.

A train is traveling at a constant speed and goes 17 kilometers in 8 minutes. How far will the train travel in 60 minutes.
Answer:
Distance B = 1275 kilometers.
Step-by-step explanation:
Let the two distances and time be A and B respectively.
Given the following data;
Distance A = 17 kilometers.
Time A = 8 minutes.
Distance B =?
Time B = 60 minutes.
First of all, we would find the constant speed;
Speed = distance/time
Substituting into the equation, we have;
Speed = 17/8
Speed = 2.125 km/m
Now, to find the distance B;
Distance B = speed * time
Distance B = 2.125 * 60
Distance B = 1275 km

PLZ HELP ASAP!!!!!!!
Answer:
angle 1 and angle 2 are supplementary angles
Step-by-step explanation:
When the base of the angles forms a straight line, the sum of the angles is 180°. That's the definition of supplementary angles.
Complementary angles form a right angle. The sum of complementary angles is 90°
A slightly silly way to remember Complementary angles: The two angles look at each other and compliment each other saying, "You look all right to me!"
"Yes, we are so right together!"

3x + 2 + x = x + 5
6 − x − 3 = 4(x − 2)
4x − 2 − 2x = x − 5
−(x + 3) = 2x − 6
Answer:
x=1
Step-by-step explanation:
You need to add the Numbers with an x together as if they were racist on each side so you'd have
4x+2 = x+5
Then to move them to either side you must do the opposite symbol of what they are so if their positive their now negative
4x-x=-2+5
then add them together
3x= 3
then divide the normal number with the number with the x
x=1
For the next problem you Multiply thr number that are in the paranthases by the number on the outside so
6-x-3 = 4(x-2)
6-x-3= 4x-8
then copy the steps that I told you from last problem
-9-x=4x-8
then
-9+8=x+4x
thenn
-1=5x
divide

how to I do Ratios with cross multiplying
Answer:
To cross multiply, multiply the numerator from one side with the denominator of the other side and put that product on one side of the equation. Do the same with the other numerator/denominator and put that on the other side. From there, solve for the unknown part.
So your ratio might look like this:
4/6=x/12
6x=12(4)
6x=48
x=8
So in this case 4/6 would equal 8/12.

Solve: 4 - 2 x 8 + (6 x 2) x 4 + 3^2
Answer:
42
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
4 - 2 × 8 + (6 × 2) × 4 + 3²
= 4 - (2 × 8) + (6 × 2) × 4 + 3²
= 4 - 16 + 12 × 4 + 9
= (4 - 16) + (12 × 4) + 9
= -12 + 48 + 9
= 45

Answer: i believe what you're looking for is W so, W=3
Step-by-step explanation: you add +7 to each side of the equation, which gives you W=3
Answer:
w= 3
Step-by-step explanation:
Add 7 to both sides of the equation w-7 = -4
w-7+7=-4+7
Simplify : w-7+7=-4+7 which simplifies to w= -4 +7
So, w = -4 +7 is w= 3

Bo' sister Anna is 3/4 his age minus 1 year. She is 11 years old.Write an equation to find Bo's age.
Answer: 16 years
Step-by-step explanation:
Let's Bo's age be represented by x.
Since Bo' sister Anna is 3/4 his age minus 1 year and she is 11 years old, this can be formed into an equation as:
(3/4 × x) - 1 = 11
3/4x - 1 = 11
3/4x = 11 + 1
3/4x = 12
Multiply both side by 4/3
x = 12 × 4/3
x = 16
Bo's age is 16 years
Answer:
x = 12 × 4/3

-7.2 as a mixed number.
Answer:
7 1/5
Explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
7.2=7.2/1
Multiply to remove 1 decimal places. Here, you multiply top and bottom by 10^1 = 10
7.2/1×10/10=72/10
Find the Greatest Common Factor (GCF) of 72 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
7/2÷2/10÷2=36/5
Simplify the improper fraction,
=7 1/5
In conclusion,
−7.2=−7 1/5
Hope it helped. :)
