You and your friend would like to build a tent that is 6 feet wide by 4 feet tall by 8 feet long. You bought a piece of canvas that is 14 feet by 10 feet to be able to make the tent. Remember you will need to put canvas on the floor of your tent. Will you have enough canvas to build the tent?
Answer:
Yes, with 12 feet leftover.
Step-by-step explanation:
For this problem, you will need to find the area of the floor and the area of both sides of the tent. To find the area of the floor, you will simply need to do 6(8) = 48. To find the area of the sides, you will need to use the Pythagorean theorem to find the height of the sides. Simply divide 6 by 2 to find b². So, the formula will be 3²+4² = c². Solve to get c = 5. Now, find the area of the rectangle by using the formula for area. 8(5) = 40. Multiply 40 by 2 because there are two sides. Now add the total area of both sides and the floor to get a total of 128. Now to see if the canvas can cover the area of the tent, do 140 - 128 to get 12. So the answer is yes, with 12 feet leftover.
Work:
Area of the floor:
6(8) = 48
Area of the sides:
A = 8(h)(2)
A = 16(h)
h² = 3² + 4²
h² = 9 + 16
[tex]\sqrt{h^{2} }[/tex] = [tex]\sqrt{25}[/tex]
h = 5
A = 8(5)(2)
A = 80
Total area of the tent:
80 + 48 = 128
Total area of the canvas:
14(10) = 140
Answer to the question:
140 - 128 = 12
By the way, sorry for the late answer. I bet this was on a test, right?

We have to solve for the ?. Let's put ? as x. So now we are solving for x.
We have to set up our equation like this:
x + 3 = 14
Since our unknown value plus 3 is equal to 14, we have to subtract 3 from 14 to get our answer.

Miko walked a distance of 1.60 km in 30 min. Find her average speed in m/s.
Miko walked a distance of 1.60 km in 30 min. Find her average speed in m/s.
Distance travelled = 1.6km = 1600m
Time taken = 30min = 30*60 = 1800s.
speed = distance/time = 1600/1800 = 0.89m/s
Evaluate the expression x2 + y2 if x = -3 and y= -2
Answer:
The Answer is 1
Step-by-step explanation:
It's 1 because x is -3 and its getting squared so its -3 times -3 which is 9. And then Y is -2 cubed so -2x-2x-2 which equals -8.
9-8=1

Find all numbers such that 16 plus 3 times the number is no more than 46. A. x > 11 B. x 11 D. x < 10
Answer:
D. x ≤ 10 (if you wrote the wrong sign)
or No answer
Step-by-step explanation:
x - the number
3x - three times the number
no more than 46 means ≤46
16 + 3x ≤ 46
3x ≤ 46 - 16
3x ≤ 30
x ≤ 30:3
x ≤ 10
The numbers are x < 10
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
16 plus 3 times the number is no more than 46.
let the number be x
then, three times the number be 3x
Lastly, not more than 46.
So,
16 + 3x ≤ 46
3x ≤ 46 - 16
3x ≤ 30
x ≤ 30/3
x ≤ 10
Hence, the number should be x < 10.

Gum is on sale. You can get 50 packages for $6.99 at the Candy Store, 40 pieces for $5.75 at Sweet Treats or 25 pieces for $4.25 at Chew-chew's. Where will you buy your gum for the best buy?
Answer:
The Candy Store
Step-by-step explanation:
In order to find the best buy, we have to find the unit price for each store. The first store we will look at is the Candy Store. To find unit prices, we must divide the price by the number of merchandise for sale, as shown here:
6.99 / 50 = 0.1398
This means each piece of gum costs a little less than 14 cents.
Moving on to Sweet Treats:
5.75 / 40 = 0.14375
Each piece of gum at this store costs a little more than 14 cents.
Last but not least, Chew-Chew's:
4.25 / 25 = 0.17
Each piece of gum here costs 17 cents.
Now, to determine which price is better, we have to go with the lowest unit price, which would be at the first shop, the Candy Store, which is your answer.
Hope this helps :)

Find the inverse of y=5x+3
Answer:
[tex]f^{-1}[/tex](x) = [tex]\frac{x-3}{5}[/tex]
Step-by-step explanation:
Rearrange the equation making x the subject
y = 5x + 3 ( subtract 3 from both sides )
y - 3 = 5x ( divide both sides by 5 )
[tex]\frac{y-3}{5}[/tex] = x
Change y to x then
[tex]f^{-1}[/tex](x) = [tex]\frac{x-3}{5}[/tex]

Aidan is running for student body president. In today’s election, he received 462 votes out of a total of 825 votes cast. What percent of votes did Aidan get?
Answer:
56%
Step-by-step explanation:
votes received/total votes = %
462/825 = 0.596 = 56%
Answer:
56% of the votes
Step-by-step explanation:
Divide 462 by 825 to get a decimal number. Then multiply the answer by 100 to get a percentage. (This moves the decimal over 2 to the right)
The number 56 is decreased to 54. What is the percentage by which the number was decreased, to the nearest tenth of a percent?
The percent of change = ((new value - old value) / old value) * 100%
In our problem,
New value = 54
Old value = 56
Let's plug our numbers in
((54 - 56) / 56) * 100% = - 3.6%
The number decreased by 3.6%
3x + 17 = 2x - 6
What’s the answer for x
