Answer:
First Question's Answer = 7 + A
Second Question's Answer = (2 x 5) x 7
Step-by-step explanation:
The commutative property of addition states that numbers can be added together in any order without changing the resulting sum.
Therefore, A + 7 = 7 + A
The associative property of multiplication states the way in which three or more terms are grouped does not change the product.
therefore, 2 x (5 x 7) = (2 x 5) x 7

Answers
Answer:
a) y = 55
b) y = 45
c) y = -18
d) y = 5.45
Step-by-step explanation:
y = 15x - 50 when x = 7
y = 15(7) - 50
y = 105 - 50
y = 55
y = 1/2x + 20 when x = 50
y = 1/2(50) + 20
y = 25 + 20
y = 45
y = (3x)2 - 36 when x = 3
y = (3(3))(2) - 36
y = 9(2) - 36
y = 18 - 36
y = -18
y = 2.5x + 3.8 when x = 0.66
y = 2.5(0.66) + 3.8
y = 1.65 + 3.8
y = 5.45

The architects side view drawing of a saltbox-style house shows a post that supports the roof ridge. The support post is 10 ft tall. How far from the front of the house is the support post positioned?
The distance between the front and the back of the house is 25 ft
Answers
Answer:
21ft
Step-by-step explanation:
We are given that the support post is 10 ft tall.
Let x represents the distance between the support post and the front of the house, that means that 25-x will be the distance from back.
By Geometric Mean Theorem, the length of the altitude to the hypotenuse of a right triangle is the geometric mean of the lengths of the segments of the hypotenuse.
So, by the previous Theorem, we get:
We got that the distance between the support post and the front of the house is 4 ft, while the distance between the support post and the back of the house is ft.
Elsa and Anna are running a race. Elsa is running at a rate of 2 meters per second and Anna is running at a rate of 1.75 meters per second. If Anna is given a 10 meter head start, how many seconds would it take for Elsa to catch up? Use an equation or system of equations to solve.
Answers
Step-by-step explanation:
Since Elsa is running at 2 and Anna at 1.75, we can first subtract
2 - 1.75 = 0.25, meaning each second Else gains 0.25m
Now that Anna was given a 10m headstart, we can divide 10 by 0.25
10/0.25 = 40
Meaning it would take 40 seconds for Elsa to catch up

A large container has a maximum capacity of 64 ounces. The container is filled with 8 ounces less than its maximum capacity. Answer parts a and b.
a. To what percent of its capacity is the large container filled?
The container is filled to 87.5% of the maximum capacity.
b. Some liquid will be poured from a full 16-ounce container until it is filled to the same percent of its capacity as the large container in part a. How many ounces of liquid must be poured from the full 16-ounce container? Explain.
Note: The answers go in the blanks
When the 16-ounce container is _____% filled, it will contain _____ ounce(s). So _____ ounce(s) will need to be poured from the full 16-ounce container.
Answers
Answer:
(a) 87.5%
(b) 90%, 14.4 oz, 1.6 oz
Step-by-step explanation:
You want the fraction full a 64 oz container is if it holds 8 oz less than its capacity. You also want to know the amount that must be transferred from a 16 oz container if both containers are to be the same fraction full.
a) FractionThe amount in the 64-ounce container is ...
64 oz - 8 oz = 56 oz
The fraction of its capacity this represents is ...
(56 oz)/(64 oz) = 7/8 = 87.5%
The container is filled to 87.5% of its capacity.
b) TransferIf x is removed from a 16-ounce container and added to the 64-ounce container, their respective fill fractions are ...
(16 -x)/16 and (56 +x)/64
We want these values to be equal, so ...
(16 -x)/16 = (56 +x)/64
4(16 -x) = 56 +x . . . . . . . . . multiply by 64
64 -4x = 56 +x . . . . . . . . . eliminate parentheses
8 = 5x . . . . . . . . . . . . . . . . add 4x-56
x = 8/5 = 1.6 . . . . . . . . . . . divide by 5
When 1.6 ounces are removed from the 16-ounce container, its fill fraction will be ...
(16 -1.6)/16 = 1 - 0.1 = 0.90 = 90%
The 16-ounce container will be 90% filled, and will contain 14.4 ounces.
So, 1.6 ounces will need to be poured from the full 16 ounce container.
__
Additional comment
After receiving 1.6 ounces, the larger container will have 57.6 ounces. Its fraction full will be 57.6/64 = 90%, as required.

Break-Even Analysis: Popcorn
The business club is going to sell popcorn at hockey games. Since they are astute business men
and business women, they know that they will not make a profit right away because they have to
pay the cost of buying a popcorn machine. They need to know how many bags of popcorn they
must sell in order to cover the set-up costs. In other words, what is the break-even point for
their popcorn business?
The red and glass popcorn carts often seen at carnivals and fairs costs $450. This is the fixed
cost. Regardless of the number of bags of popcorn they make and sell, the machine cost will not
change.
1. The popcorn, butter, salt, and serving bags cost $15 for every 100 bags of popcorn. What is
the cost per bag for these consumables?
$15 per 100 bags = $.15 per bag
The variable cost changes depending on how many bags of popcorn they make. The more
popcorn they make, the more they spend on popcorn, butter, salt and bags. The variable cost is
$0.15 times the number of bags of popcorn.
The total cost is the variable cost plus the fixed cost.
Total Cost = Variable Cost+Fixed Cost
2. Write an equation for the Total Cost as a function of the number of bags of popcorn made.
Use the notation C(x) for total cost, and let x be the number of bags of popcorn they make.
((x) =115x+450
Each bag of popcorn sells for $1.00. The revenue is the amount of money they receive from
selling bags of popcorn. If they sell 20 bags of popcorn, they will receive $20, since each bag
sells for $1. The revenue they take in is the price per bag of popcorn multiplied by the number of
bags of popcorn sold.
(Price per Item) (Number of Items)

Answers
Answer:
Step-by-step explanation:
here you go hit this link
Answer: Price per Bag * Number of Bags = $1 * x = R(x)
To find the break-even point for the popcorn business, you need to find the number of bags of popcorn that need to be sold in order to cover the total cost, which includes the fixed cost of the machine and the variable cost of the consumables.
Calculate the cost per bag of popcorn for the consumables:
$15 for every 100 bags of popcorn ÷ 100 bags = $0.15 per bag.
Write an equation for the total cost as a function of the number of bags of popcorn made:
Total Cost = Variable Cost + Fixed Cost
Variable Cost = $0.15 * Number of Bags
Total Cost = $0.15 * Number of Bags + $450
Let C(x) represent the total cost where x is the number of bags of popcorn.
C(x) = $0.15 * x + $450
Write an equation for the revenue as a function of the number of bags of popcorn sold:
Revenue = Price per Bag * Number of Bags
Price per Bag = $1
Revenue = $1 * Number of Bags
Let R(x) represent the revenue where x is the number of bags of popcorn.
R(x) = $1 * x
Set the revenue equation equal to the total cost equation and solve for x, the number of bags of popcorn that need to be sold to reach the break-even point:
R(x) = C(x)
$1 * x = $0.15 * x + $450
$0.85 * x = $450
x = $450 ÷ $0.85 = 529 bags
Therefore, the business club needs to sell 529 bags of popcorn in order to reach the break-even point and cover their costs.

This is because if you find the GCF of 6 and 12 you will get 3.
3(p+m) hence why three is at the beginning.
you will then divide 6 and 12 by three and put them inside the parentheses with their corresponding variable.
3(2p+4m)
if you multiply this you will get
6p+ 12m

Step-by-step explanation: for 3 you have yo find what is equivalent to 6p+12m so the answer is c. 6(p+12M) for 4 you are explaining what will happen if g is 1 and g is 3. for 5 you have to explain what is the constant rate.
When rolling a 6-sided die twice, determine P(sum of 4).
A. 3/36
B. 5/36
C. 6/36
D. 2/6
Answers
the probability of rolling a sum of 4 when rolling a 6-sided die twice is,
⇒ 3 / 36.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Now, To determine the probability of rolling a sum of 4 when rolling a 6-sided die twice, we need to first find all the possible outcomes when rolling a die twice.
Since, There are 6 possible outcomes when rolling a single die:
1, 2, 3, 4, 5, or 6.
Now, When rolling two dice, we can combine each of these outcomes with every other outcome.
Hence, This gives us a total of 6 x 6 = 36 possible outcomes when rolling two dice.
Thus, To find the number of outcomes that add up to 4, we can list them out:
1 + 3
2 + 2
3 + 1
So, there are three possible outcomes that add up to 4.
Hence, To find the probability of rolling a sum of 4, we need to divide the number of outcomes that add up to 4 by the total number of possible outcomes:
⇒ P(sum of 4) = 3/36
Therefore, the probability of rolling a sum of 4 when rolling a 6-sided die twice is 3 / 36.

An engineer needs to create a bridge that consists of right triangles for support. Determine whether the triangle shown is a right triangle.
Be sure to include your answer and show/explain the steps you used to solve.
Answers
Answer:
See below
Step-by-step explanation:
We can see that the thick line which outlines the main cable, the base and tower form a triangle
The longest length is the main cable which is 15m
If it is indeed a right triangle. the squares of the sums of the two shorter sides must equal the square of the longer side.
Sum of squares of shorter sides(also called legs) = 9² + 12²
= 81 + 144
= 225
Square of the longer side = 15² = 225
Since 15² = 9² + 12²
the triangle shown is indeed a right triangle with hypotenuse = 15m and the legs of the right triangle 9m and 12m
