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

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

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.

Reece has $12. Suppose the function f(x)=1.5x+7 represents the cost to rent x video games each month. How many more dollars will Reece need to rent 8 video games next month?
Answer:
$7Step-by-step explanation:
given that the expression is
f(x)=1.5x+7
the expression is the cost
Reece has a total of $12
and that x represents the number of game
let us solve for the cost for 8 games
f(x)=1.5(8)+7
f(x)=12+7
f(x)=19
the cost of 8 game is $19
since he has $12 he need extra 19-12= $7

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.

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.

If f(x) = 2 sin(x) and g(x) = sin(2x), which of the following statements is true?
A
The graph of g(x) and the graph of f(x) are identical
The amplitude of g(x) is greater than the amplitude of f(x)
The amplitude of f(x) is greater than the amplitude of g(2)
D
O
The period of f(x) is half of the period of g(x)
Answer:
The correct options are;
The amplitude of f(x) is greater than the amplitude of g(x)
Step-by-step explanation;
The given functions are plotted
From the graphs, we have;
The amplitude of f(x) is larger than the amplitude of g(x)
The graphs of g(x) and f(x) are not identical
The period (the time taken to complete one cycle) of g(x) is half the period of f(x)
The observed properties are due to the fact that the maximum value of the sine function are ±1, and the period of the sine function is 2·π or 360°.
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

Step-by-step explanation:
Since we know she is averaging $0.87 a day for the month of March, which has 31days; you would multiply .87 and 31 to get your answer.
.87*31=26.97(Electrical cost for the month of March)
An aircraft carrier traveled to a navigational buoy and back. It took six hours longer to go there than it did to come back. The average speed on the trip there was 10 mph. The average speed on the way back was 22 mph. How many hours did the trip there take?
Answer:
11 mph
Step-by-step explanation:
Given that:
Average speed on the trip = 10 mph
Average speed on the way back = 22 mph
Let time taken on the trip to navigational buoy = [tex]t[/tex] hours
As per question statement, Time taken on the way back = [tex]t+6[/tex] hours
Formula used:
[tex]Distance = Speed \times Time[/tex]
The distance traveled on the way to navigational buoy and the distance traveled on the way back are traveled.
Writing equation:
[tex]22t=10(t+6)\\\Rightarrow 22t=10t+60\\\Rightarrow 22t-10t=60\\\Rightarrow 12t=60\\\Rightarrow t=5\ hours[/tex]
It is given that the time taken in the trip is 6 hours more than that of time taken on the way back.
So, time taken on the trip = 6 + 5 = 11 mph
