The bells are adding a new room to their house. The room will be a cube with volume 8000ft3. They are going to put in hardwood floors, and the contractor charges10 $ per square foot. How much will the hardwood floors cost? The hardwood floors will cost $
Given:
Volume of a cubed room = 8000 cubic ft
Cost of floor hardwood = $10 per square foot
To find:
The total cost of floor hardwood.
Solution:
Let the each side of cubed room be x ft.
Volume of a cube is cube of its side.
Volume of a cubed room is 8000 cubic ft. So,
[tex]x^3=8000[/tex]
Taking cube root on both sides.
[tex]x=20[/tex]
So, length of each of room is 20 ft.
Area of base = length × breadth
So, area of base of room is
[tex]20\times 20=400\text{ ft}^2[/tex]
It means, 400 sq ft hardwood is required for the floor.
Cost of floor hardwood is $10 per square foot. So, total cost of hardwood floor is
[tex]400\times 10=4000[/tex]
The hardwood floors will cost $4000.

Could you please help me with this question and explain it thoroughly?
Step-by-step explanation:
the answer is 50 because 2x-=76 is k :)
Answer:
k (oats in cups) = 25 (grams of almonds)
Step-by-step explanation:
If you look at the coordinates given in the question (1,k) where we are told to find k.
A coordinate is a pair of one x and y value, an input and output in a relationship.
2d coordinates are in the form of (x,y), this means that (1,k) is representing what k will be when x is 1. So to find k, we must look at where y (the amount of almonds in this instance) is when x (the oats) is 1.
This graph looks to be y = 25x.
Where y is the oats in cups, and x is the grams of almonds. This is a proportion which means that there are 25 grams of almonds for every 1 cup of oats.

Answer:
340 total people (see below)
Step-by-step explanation:
So first, you need to find the number of children. To do that, the percentage of adults must be 55% because is 45% of 100% are children, the remaining are adults. You can use a ratio to find the amount of children:
x children = 45%
187 adults 55%
Now, cross multiply:
55x = 187 (45)
55x = 8415
x = 8415/55
x = 153
There are 153 children.
To find the total amount of people in the theater, add the two amounts:
187 adults + 153 children = ? people
= 340 people
James gets $6 for his weekly allowance and spends $4 of it. His brother Mike gets $7 for his weekly allowance and spends $3 of it. Their mother's birthday is in 4 weeks. If they spend the same amount each week, how much money can they save together in that time to buy her present? 2 points
Answer:
$24
Step-by-step explanation:
James
Allowance per week = $6
He spends = $4
Balance = $6 - $4 = $2
Mike
Allowance per week = $7
He spends = $3
Balance = $7 - $3 = $4
Their mother's birthday is in 4 weeks
how much money can they save together in that time to buy her present?
James savings per week × 4 weeks
= $2 × 4
= $8
Mike's savings per week × 4 weeks
= $4 × 4
= $16
Total amount James and Mike can save together = $8 + $16
= $24

Answer:
[tex]\frac{7}{24}[/tex]
Step-by-step explanation:
To factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...).
The number of times that each prime divides the original integer becomes its exponent in the final result. In our example, Prime number [tex]2^3=8[/tex]
[tex]\frac{3*7}{2^3*3^2}[/tex]
We need to perform a multiplication. The following rule is applied:
[tex]\frac{A}{B}*\frac{C}{D}=\frac{AC}{BD}[/tex]
In our example, the factors in the new numerator are 3,7
The factors in the new denominator are [tex]2^3, 3^2[/tex]

please let me know if you have the asers
Answer:
468
Step-by-step explanation:
and this is how you spell answers
The value of 78 × 6 is 468
What is multiplication?Multiplication is the process of calculating the product of two or more numbers. The result of multiplication is called product.
If a × b = c , this means that a and b are the factors and c is the product.
For example if each student has 5 apples and there are 100 students in the camp, the total number of apples in the camp is
100 × 5 = 500 mangoes.
Similarly, 78 × 6
= 70 × 6 + 8 × 6
= 420 + 48
= 468
Therefore the product of 78 and 6 is 468

Exercise 1. A truck has the capacity to transport up to 8 tons of a material at a time. If 104 tons of the material should be transported, how many trucks like this will be needed?
Answer:
how many trucks ?
Step-by-step explanation:
It is solved using the rule of three simple ones, where the number of trucks is for the quantity of material transported. We have that 1 is for 8 as X is for 104 (Look attached).
Multiplying cross, we have to:
8X = 104
X = 104/8
X= 13
Evaluate 6x – y if x = 5 and y = 8.

Sharonda uses a blend of dark chocolate and milk chocolate to make the ice cream topping at her restaurant. She needs to buy 120\,\text{kg}120kg120, start text, k, g, end text of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate. Let ddd be the number of kilograms of dark chocolate she buys and mmm be the number of kilograms of milk chocolate she buys.
Step-by-step explanation:
ATQ,
Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.
She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.
So,
m = 2d .....(1)
m + d = 120 ...(2)
We can also solve the above equations,
Put m = 2d in equation (2)
2d + d = 120
3d=120
d = 40
Put d = 40 in equation (1)
m = 2(40)
m = 80
Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.
Answer:
d+m=120
d=2m

Answer:
You bought 3 spiral notebooks.
Step-by-step explanation:
This can be represented as 1x + 2 = 5. To solve this, first subtract 2 from both sides. You are left with 1x = 3. Divide by 1 to both sides, and your answer is x = 3.
