Answer:
4 pounds of each item
Step-by-step explanation:
A supplier sells 2 1/4 pounds of mulch for every 1 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and gravel combined. How many pounds of each item does the supplier sell? (Ratios and Rates)
Mulch = 2 1/4 pounds
= 9/4 Pounds
Gravel = 1 1/3 pounds
4/3 pounds
Total items sold = 172
Let x = pounds of each item the supplier sells
Mulch : gravel
9/4 : 4/3
Change into whole number by multiplying by 12
(9/4)12 : (4/3)12
= 108/4 : 48/3
= 27 : 16
Mulch : gravel = 27 : 16
27x + 16x = 172
43x = 172
Divide both sides by 43
x = 172 / 43
= 4
x = 4 pounds
Check
27x + 16x = 172
27(4) + 16(4) = 172
108 + 64 = 172
172 = 172
Therefore, the supplier sells 4 pounds of each item

Amy types at an average speed of 38 words per minute. She has already typed 1,450 words of her final paper, which will be more than 4,000 words. Which inequality can be used to solve for x, the number of minutes it will take Amy to finish typing her paper?
Answer:
D. 38x + 1,450 > 4,000
Step-by-step explanation:
A. 38x − 1,450 > 76
B. 38(x + 1,450) > 4,000
C. 38x > 4,000
D. 38x + 1,450 > 4,000
Let
x = number of minutes it will take Amy to finish typing her paper
Amy types at an average speed of 38 words per minute
That is, it will take Amy 38x minutes to type her final paper
She has already typed 1,450 words
Amy wants to type her final paper, which will be more than 4,000 words
That is > 4,000
The inequality is
38x + 1,450 > 4,000
The correct answer is
D. 38x + 1,450 > 4,000
Answer:
D. 38x + 1,450 > 4,000

Describe a rigid motion or composition of rigid motions that maps the rectangular bench at (10,0) and the adjacent flagpole onto the other short rectangular bench and flagpole
Answer:
The answer is below
Step-by-step explanation:
Describe a rigid motion or composition of rigid motions that maps the rectangular bench at (0,10) and the adjacent flagpole onto the other short rectangular bench and flagpole
Solution:
The other short rectangular bench is at (0, -10), while the short flagpole at (2, 10)
Transformation is the movement of a point from its initial location to a new location. If an object is transformed then all its points are also transformed. Types of transformation are reflection, dilation, rotation and translation.
If a point X(x, y) is reflected across the x axis, the new point is (x, -y)
If a point X(x, y) is reflected across the y axis, the new point is (-x, y)
Therefore the rectangular bench at (0,10) is reflected across the x axis to give the other short rectangular bench at (0, -10) while the adjacent flagpole at (-2,10) is reflected across the y axis to give the other flagpole at (2, 10)

Two rival dry cleaners both advertise their prices. Store A's prices are modeled by the expression , where x is the number of items brought in. Store B's prices are modeled by the expression , where x is the number of items brought in. When do the two stores charge the same rate?
Here is the full question
Two rival dry cleaners both advertise their prices. Store A's prices are modelled by the expression (15x -2), where x is the number of items brought in. Store B's prices are modelled by the expression 3(5x+7) , where x is the number of items brought in. When do the two stores charge the same rate?
Answer:
The two stores cannot charge at the same rate.
Step-by-step explanation:
From the information given above:
Two rival dry cleaners both advertise their prices.
Store A's prices are modelled by the expression (15x -2)
Store B's prices are modelled by the expression 3(5x+7)
The objective is to determine the period at which the two stores charges at the same rate;
To do that, we need to equate the expression in store A and B
i.e.
15x - 2 = 3(5x + 7)
Open brackets
15x - 2 = 15x + 21
Deduce both sides by - 15x
- 2 = 21
Therefore; since the value of x cannot be estimated, then the two stores cannot charge at the same rate.

Shelley's pet food store sold one customer 5 peanut butter biscuits for $3. She sold another customer 7 beef treats for $4.20. Write a proportion that compares the sales of these two items, and find the cross products. The cross products are both equal to
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Customer 1:
5 peanut butter biscuit = $3
Price per product sold :
Number Sold / price
= 5/3
Customer 2:
7 beef treats for $4.20
Price per product sold :
Number Sold / price
= 7/4.20
The cross product :
5/3 = 7 / 4.20
Cross multiply
5 * 4.20 = 3 * 7
21 = 21
Cross product of both = 21
A factory is testing its water filters to see how many days they remain effective. A trial of 10 filters shows the effective days of each filter to be 94, 101, 120, 87, 93, 91, 105, 92, 91, and 100. What is the range of effective days of the trial water filters?
Answer: 33
Step-by-step explanation:
From the question, a trial of 10 filters shows the effective days of each filter to be 94, 101, 120, 87, 93, 91, 105, 92, 91, and 100.
The range of effective days of the trial water filters will be the difference between the highest number given and the smallest number given.
Highest number = 120
Lowest number = 87
Range = 120 - 87 = 33
Both circles have the same center. The circumference of the inner circle is 150.72 feet. What
is the area of the shaded region?
Answer:
Step-by-step explanation:
The circumference = 2 * pi * r = 150.72
Use this fact to find r
2*pi*r = 150.72 Divide by pi
2*r = 150.72 / 3.141
2*r = 47.985 Divide by 2
r = 23.9923
Now that you have the radius of the inner circle, use it to find the area.
Area = pi * r^2
Area = 1808.064
Now we need the radius of the outer circle
r = 23.9923 + 11
r = 34.9923
Find the area of the other circle
Area = pi * 34.9923^2
Area = 3846.032
Finally the area of the shaded region is the area of the large circle - the area of the small circle
Area of the shaded area = 3846.032 - 1808.064
Area of the shaded area = 2037.97 to the nearest hundredth.

Cora has 6.6 feet of silver wire in her craft box. She plans to use the wire to make jewelry for her friends and family. She needs 0.6 feet of wire to make a bracelet and 1.4 feet of wire to make a necklace. If Cora makes 4 bracelets, how many necklaces can she make with the leftover wire?
Answer:3 necklaces
Step-by-step explanation:
6.6=0.6x+1.4y
6.6=0.6(4)+1.4y
6.6=2.4+1.4y
6.6-2.4=(2.4-2.4)+1.4y
4.2=1.4y
4.2/1.4=1.4/1.4y
y=3
Cora can make total of 3 necklaces with the leftover wire.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
Total length of wire that Cora has = 6.6 feet
Length of wire needed to make a bracelet = 0.6 feet
Length of wire needed to make a necklace = 1.4 feet
Cora has made 4 bracelets.
Length of wire used for 4 bracelets = 4 × 0.6 = 2.4 feet
Remaining length = 6.6 feet - 2.4 feet = 4.2 feet
Number of necklaces which can be made using the remaining wire is,
= 4.2 / 1.4
= 3
Hence Cora can make 3 necklaces with the remaining wire.

You have a summer job mowing lawns. You mow 3 lawns in 5 hours. How long will it
take to mow 9 lawns. Explain your thinking.
Answer:
15 hours
Step-by-step explanation:
2 ways to do this
1- I know that 3 x 3 is 9 hours which will leads to these equations
3 x 3 = 9
5 x 3 = 15
2- Find out how long it takes for one lawn
5/3 = 1.6666...
1.6666.... x 9 =15
I hope Im correct!
Answer:
it would take 15 hours
Step-by-step explanation:
If we know that it would take 5 hours to mow 3 lawns, then we can assume that this ratio will stay the same and multiply this by 3, making it 9 lawns in 15 hours
Movie Mania requires customers to pay a sign-up fee of $20, and charges $4.00 to rent a DVD. Hurricane Video is free to join, but DVDs cost $6.00 to rent. Write and solve an equation to find the number of DVDs you would have to rent in order for both stores to charge the same. Explain what your variable represents. A. Let n = the cost of renting a movie; 20n + 4 = 6; 40 videos B. Let n = the number of DVDs rented; 20 + 4n = 6n; 10 videos C. Let n = the cost of renting a movie; 20n + 4 = 6; 2 videos D. Let n = the number of DVDs rented; 20 + 4n = 6n; 40 videos
Answer:
B. Let n = the number of DVDs rented; 20 + 4n = 6n; 10 videos
Step-by-step explanation:
Let n = number of DVDs to rent
Movie Mania = 20 + 4n
Hurricane = 6n
Equate the cost of renting a DVD in both stores
Movie Mania = Hurricane
20 + 4n = 6n
20 = 6n - 4n
20 = 2n
Divide both sides by 2
n = 20 / 2
= 10
n = 10
The correct answer is
B. Let n = the number of DVDs rented; 20 + 4n = 6n; 10 videos
