Answer:
She pays 0. 05$
Step-by-step explanation:
Cost per once is 40, peanut butter is 5. 20 divide those 2 you will get 0. 13
Now divide it by the butter price 2. 70/15
It will be 0. 18
Subtract 0. 18-0. 15
Mia can purchase a 40-ounce jar of peanut butter for $5.20 or a 15-ounce jar for $2.70. How much does Mia save per ounce by buying the 40-ounce jar?
She pays 0.05$
Stephen purchased a guitar, which was originally priced at $80 but
discounted at 25%. He also had to pay 5% sales tax. What amount did
Stephen pay to purchase the guitar? *
Answer:
57 dollars
Step-by-step explanation:
1. Solving the 25% discount
25% = .25
80 x .25 = $20
80 - 20 = $60
** We subtracted 80 from 20 because 25% of 80 is 20 BUT We're taking 25% OFF of 80 because it was a discount.
2. Solving the 5% Tax
5% = .05
$60 x .05 = 3
$60 + 3 = $63
**Adding tax to the discounted price
I hope this helps!
what are equations?
how do we solve equations?
Answer:
An equation is a mathematical statement that has an equal symbol between two algebraic expressions that have the same value
Step-by-step explanation:
We solve equations with math.
Solve the equation 1.5x + 18 =3
Answer:
x=10
Step-by-step explanation:
Simplifying
1.5x + 3 = 18
Reorder the terms:
3 + 1.5x = 18
Solving
3 + 1.5x = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 1.5x = 18 + -3
Combine like terms: 3 + -3 = 0
0 + 1.5x = 18 + -3
1.5x = 18 + -3
Combine like terms: 18 + -3 = 15
1.5x = 15
Divide each side by '1.5'.
x = 10
Simplifying
x = 10
Courtney and Chelsea are leading a family hike on Saturday. The number of snacks Chelsea is bringing can be represented by 2x. Courtney is bringing a number of snacks. If Chelsea brought 16 snacks, how many did Courtney bring?
Answer:
Courtney is bringing 8 snacks
Step-by-step explanation:
Chelsea's snacks are represented as 2x.
2x means 2 · (a number)
If Chelsea brought 16 snacks and the amount of snacks represented by 2x, we have to figure out what times 2 equals 16.
In order to find out, we have to divide.
16 ÷ 8 = 2
This means 2 · 8 = 16
Since the amount of snacks Courtney brings is represented as "x", she would have brought 8 snacks.
Hope this helped! :)

True or False: An asymptote is a line in which a graph gets close to but never crosses.
True
False
Answer:
True
Step-by-step explanation:
An asymptote is, essentially, a line that a graph approaches, but does not intersect. For example, in the following graph of y = 1x y = 1 x , the line approaches the x-axis (y=0), but never touches it. No matter how far we go into infinity, the line will not actually reach y = 0, but will always get closer and closer.
The statement is true.
What is an asymptote?Asymptote is a line that a curve approaches as it moves towards infinity. Asymptotes. The curves visit these asymptotes but never overtake them.
An asymptote is a line along which the values of a function approaches but never reach, such that one or both of the or coordinates tend to positive or negative infinity. Therefore, the graph of a rational function never intersects any of its asymptotes.
Hence, the statement is true.

Karl set out to alaska on his truck the amount of fuel remaining in hi truck tank in liters as a function of distance driven in kilometers is graphed
What distance did Karl travel by the time he had 200 liters of fuel
Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.
Why it is and what is distance?
To determine the distance Karl traveled by the time he had 200 liters of fuel remaining in his truck, we need to examine the graph provided.
From the graph, we can see that when the fuel remaining in the truck tank is 200 liters, the corresponding distance driven is approximately 420 kilometers.
Therefore, Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.
Distance is the physical length between two points or objects. It is a scalar quantity that measures the amount of space between two locations, without regard to the direction of travel. Distance can be measured in various units such as meters, kilometers, miles, and so on.
In physics, distance is often distinguished from displacement, which is a vector quantity that measures the change in position of an object relative to its starting point.

Step-by-step explanation:
Answer:
You have to write the number-line out man. However, the answer is -2
Step-by-step explanation:
When solving problems like these, knowledge or integers and whole numbers are important. First, find the absolute values of both numbers.
Absolute value of -6: 6
Absolute value of 4: 4
Subtract the values: 6 - 4 = (Positive 2)
THEN, look at the number with the Greater Absolute value. In this case, it is -6. Because -6 has the greater absolute value, your answer should be the connotation of that number. IN THIS CASE, the number with the greater absolute value, -6, has a negative sign. Therefore, your answer should be negative. Your answer is -2.

Beth normally cycles a total distance of 56 miles per week.
She increases her distance by 15% each week for the next three weeks.
How many miles will she cycle in the third week?
(3 marks)
miles
Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
Beth will cycle a distance of 85.169 miles in the third week.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If john obtained a score of 57% on his exam, that corresponds to 57 out of 100.
Beth rides her cycle 56 kilometers each week on average.
For the next three weeks, she will increase her distance by 15% each week.
As per the given condition, the required solution would be as
⇒ 56 / 100 = 0.56
⇒ 0.56 × 15 + 56 = 64.4
If we obtain 15%, add 56 (the initial amount) because there is a 15% increase.
Repeat for the remaining three weeks.
⇒ 64.4 / 100 = 0.644
⇒ 0.644 × 15 + 64.4 = 74.06
⇒ 74.06 / 100 = 0.7406
⇒ 0.7406 × 15 + 74.06 = 85.169
Therefore, she will cycle a distance of 85.169 miles in the third week.

Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.
