The amount of gasoline that was in the tank before refilling it was 11.5 gallons. Due to the above, it lacked 8.5 gallons to refill it again.
How to calculate how many gallons were missing to fill the tank?To calculate how many gallons were left to refill the tank, you need to know how much gasoline was in the tank.
According to the statement, the tank required [tex]8 \frac{5}{10}[/tex] to fill up, then to know how much gasoline it had we must subtract this amount from the maximum capacity of gasoline that the tank requires as shown below:
[tex]8\frac{5}{10}[/tex] = 8.5 gallons
20 - 8.5 gallons
= 11.5 gallons
Based on the above, the number of gallons in the tank was 11.5 gallons of gasoline.

Ramona deposits $2,500 into a savings account that pays 4.5% interest compounded annually. If Ramona makes no deposits or withdrawals, how much interest will her money earn after 3 years? Record your answer in the boxes. Then fill in the bubbles. Be sure to use the correct place value.
Answer: She will earn $352.92 as interest.
Step-by-step explanation:
Formula for compound interest[tex]= P((1+r)^t-1)[/tex]
, where P= principal value, r = rate of interest(in decimal) , t= time
As per given , we have
P = $2,500
r = 4.5% = 0.045
t= 3 years
then, Compound interest = [tex]2500((1+0.045)^3-1)=2500((1.045)^3-1)[/tex]
[tex]=2500(1.141166125-1)=2500(0.141166125)\\\\\approx\ \$352.92[/tex]
Hence, she will earn $352.92 as interest.

Step-by-step explanation:
First Solution
X=7
4= 12
Making X Subject of the formula
we have,
X= 7×4 = 28 = 14 = 7
12 12 6 3
OR
You cross multiply
X multiplies 12= 12X
7 multiplies 4= 28
you now have 12X=28
divinding both sides by 12,
12 cancels 12 and leave X
Answer:
x = [tex]\frac{7}{3}[/tex]
Step-by-step explanation:
[tex]\frac{x}{4}[/tex] = [tex]\frac{7}{12}[/tex] ( cross- multiply )
12x = 28 ( divide both sides by 12 )
x = [tex]\frac{28}{12}[/tex] = [tex]\frac{7}{3}[/tex] ← in simplest form
Please really need the correct answer for this or I'll fail algebra 3
Answer:
[tex]4\pi[/tex]
Step-by-step explanation:
S = Arc Lenth
θ = Radians
R = Radius
S = θR
So, now that we understand the formula, we will convert 72° into radians by introducing the equation [tex]x*\frac{\pi }{180}[/tex], x = 72
S = [tex]72*\frac{\pi }{180} * R[/tex]
given that R = 10
S = [tex]\frac{72*10*\pi }{180}[/tex]
S = [tex]\frac{720*\pi }{180}[/tex]
We simplify 720 as 180 goes into 720 4 times and we get
S = [tex]4\pi[/tex]

Question 1 (1 point) A locksmith charges $25 to make a house call and $15 for each lock re-keyed. Another locksmith charges $10 to make a house call and $20 for each lock that is re-keyed. Write a system of equations and use them to determine the number of locks where the total cost is the same. What will be the total cost? (Hint: write 2 equations of the form y = mx + b)
Answer:
The number of locks will be 3
The total cost = $50
Step-by-step explanation:
We are trying to write the equations of the cost in the form of the equation of a straight line
The equation will be;
C = F + 15r
where F is the price for house lock , C is total cost and r is the amount per rekey
For the first locksmith;
His equation will be ;
C = 25 + 15r
For the second
C = 10 + 20r
If the total cost is the same for both;
then;
10 + 20r = 25 + 15r
20r - 15r = 25 - 10
5r = 15
r = 15/5 = 3
For the total cost to be same, number of locks is 3
The total cost will be ;
C = 20 + 10(3) = 20 + 30 = $50

Maria is trying to estimate 30. She uses this table of values
What should she do next to find 30 to the nearest hundredth?
A. She should find the squares of numbers between 5.5 and 5.6.
B. She should estimate that 30 is 5.50.
C. She should find the squares of numbers between 5.4 and 5.5.
D. She should find the average of 5.4 and 5.5.
The correct answer for the given question is C. She should find the squares of numbers between 5.4 and 5.5.
What is square of a number?Square of a number is the product of integer with itself.
Now it is given that Maria is trying to estimate 30.
To find the value of 30 let us take the root of 30.
So, √30 = 5.4772
Since 7 to the right of 7 is greater than 5
Round to the nearest hundredth,
√30 = 5.48
Hence, 5.48 is the nearest square of 30.
From the table we see that the nearest digit to the 30 is 5.4² and 5.5²
The value of 5.4² given in the table is 29.2.
and the value of 5.5² given in the table is 30.3.
Hence,she should do next to find 30 to the nearest hundredth is to find the squares of numbers between 5.4 and 5.5.
Therefore,The correct answer is C. She should find the squares of numbers between 5.4 and 5.5.

Read the passage.
(1) Ask young people today if they know of anyone who has had smallpox, and they might ask, "What’s smallpox?” (2) That is because this disease was eradicated from the planet decades ago, thanks to vaccinations. (3) Despite the obvious effectiveness of vaccination, opponents of this procedure argue that humans are better off fighting diseases on their own without adding anything potentially harmful to their bodies. (4) Still, the American Academy of Pediatrics says that vaccines can be 99 percent effective, and the Centers for Disease Control claims that, over a 10-year period, vaccines allowed 322 million children to avoid illnesses. (5) So the next time someone tells you that vaccines are poisoned apples that will lead to a fate like Snow White’s, counter their argument with the facts. (6) The bottom line is that vaccines are safe to use and save lives.

Working alone, Darryl can oil the lanes in a bowling alley in ten hours. Ming can oil the same lanes in eight hours. Find how long it would take them if they worked together. Round to the nearest tenth.
(Part 1 of asking for help)
Answer:
9.1
Step-by-step explanation:
If Darryl and Ming worked together they takes 4.4 hours to complete the work.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, Working alone, Darryl can oil the lanes in a bowling alley in ten hours. Ming can oil the same lanes in eight hours.
Darryl can oil the lanes in a bowling alley in one hour = 1 /10
Ming can oil the same lanes in one hour = 1 / 8
The time it takes to work together,
1 / t = 1 / 10 + 1 / 8
1 / t = 10+8 / (10 × 8)
1/t = 9 / 40
t = 40/9
t = 4.4 hours
Thus, if Darryl and Ming worked together it takes 4.4 hours to complete the work.

Answer:
x=12
Step-by-step explanation:
For the given situation , a quantity x is added to [tex]\frac{1}{4} x[/tex] gives 15.
We can set up equation as
[tex]x+\frac{1}{4}x=15[/tex]
Multiply each term by 4 on both sides to get rid the denominator.
It gives,
4 x+x=60
Now, combine like terms
5 x=60
Divide both sides by 5
x=12.
