Lisa ran 3 1/2 miles in 21 minutes at that rate how long will it take her to run 5 miles
Answer:30
Step-by-step explanation: please
Lisa take approximately 30 minutes(time) to run 5 miles at the same rate she ran 3 1/2 miles in 21 minutes.
To find out how long it will take Lisa to run 5 miles at the same rate, we can set up a proportion using the distance and time data.
Let's denote the time it will take her to run 5 miles as "t" (in minutes).
The proportion can be set up as follows:
(3.5 miles) / (21 minutes) = (5 miles) / (t minutes)
Now, cross-multiply and solve for "t":
3.5 × t = 21 × 5
3.5t = 105
Divide both sides by 3.5 to isolate "t":
t = 105 / 3.5
t = 30
So, it will take Lisa approximately 30 minutes to run 5 miles at the same rate she ran 3 1/2 miles in 21 minutes.

Total number of students in grade 9-10 = 125
The percentage of the students in grades 9–10 who like rap music will be:
= Number of students in grade 9-10 who likes rap / Total number of students in grade × 100

Answer:
Mike can buy 7 model cars
Step-by-step explanation:
The equation for this word problem would be
7.5x+20=75
subract 20 from both sides
7.5x=55
divide both sides by 7.5
x= 7.33 or 7 1/3 or 22/3
but since you cant buy a third of a car the answer would be 7

Analyze the diagram below and complete the instructions that follow.
Find the value of x.
Answer:
C. 10
Step-by-step explanation:
Two sides of the right triangle are equal to each other, which is 5√2.
The third side is the hypotenuse length = x
We can use pythagorean theorem to find x.
Thus,
c² = a² + b²
Where,
a = 5√2
b = 5√2
c = x
Therefore:
x² = (5√2)² + (5√2)²
x² = 50 + 50
x² = 100
x = √100
x = 10

In 1976, a certain model of car cost $5,000. What would be the cost of that car in 2012 dollars? Express your answer rounded to the nearest cent
Answer:
The cost of that car in 2012 dollars is $20,755
Step-by-step explanation:
We take a look at inflation values of the dollar to solve this question.
100 dollars in 1976 are equivalent to 469.48 dollars in 2021.
100 dollars in 2012 are worth 113 dollars today.
So, to find the 2012 equivalent, we divide 469.48 by 113/100 = 1.13. So
469.48/1.13 = 415.5.
That is, 100 dollars in 1976 are equivalent to 415.5 dollars in 2012, that is, 1 dollar in 1976 was worth 4.155 dollars in 2012.
In 1976, a certain model of car cost $5,000. What would be the cost of that car in 2012 dollars?
Multiplying by 4.155
5000*4.155 = 20,755
The cost of that car in 2012 dollars is $20,755
To prepare for a lab experiment, Ted is making a solution that uses two types of concentrations of HCI ( hydro boric acid) 80 ml of 50% HCI solution, and 120 mlL of 20% HCI solution. What is the HCI concentration of the mixes solution
Answer:
32%
Step-by-step explanation:
50% of the first solution is HCL, so it has
80 ml x 50% = 80 ml x 0.5 = 40 ml of HCL
Similarly the second solution has 20% of HCL, so
120 ml x 20% = 120 ml x 0.2 = 24 ml of HCL
The combined solution will have 40 ml + 24 ml = 64 ml of HCL.
The total volume of the 2 solutions is 80 ml + 120 ml = 200 ml.
We can now calculate the concentration of HCL in the mixed solution, by dividing the volume of HCL by the total volume of the solution,
64 ml / 200 ml = 0.32 = 32%

A rectangular garden has an area of 3/5 square miles. If its length is 7/8 miles, what is its
width?
Input your answer as a fraction.
Answer:
[tex]\frac{24}{35}mi[/tex]
Step-by-step explanation:
Area = length • width
area = [tex]\frac{3}{5}mi^{2}[/tex]
length = [tex]\frac{7}{8} mi[/tex]
width = x
[tex]\frac{3}{5} = \frac{7}{8} x[/tex] multiply both sides by [tex]\frac{8}{7}[/tex] (the reciprocal of [tex]\frac{7}{8}[/tex])
[tex](\frac{8}{7})(\frac{3}{5}) = x[/tex]
x = [tex]\frac{24}{35}[/tex]

Olivia’s passcode has four digits. The second digit from the left is three times the first (left-most) digit. The number formed by the last (right-most) two digits is three times the second digit from the left. The sum of the digits is 21. What is Olivia’s passcode?
Answer:
3927
Step-by-step explanation:
How I did this was just trial and error. 1315 doesn’t work as it only adds up to 10. Lets try 2618. It still only adds up to 17. Let’s try 3927. It Works! Many get confused as they assume “The number formed by the last (right-most) two digits is three times the second digit from the left.” As adding up the last two digits. However, getting 21 is not possible considering the circumstances If you add the last two digits as a multiple. If you have 1234, the 3” and 4” aren’t separate numbers. The 3” and 4” is 34” not 3+4.
3+9=12. 12+2=14. 14+7=21.
Using the hit and trial method and the given condition Olivia's passcode can be determined. Olivia's passcode is 3927.
Given :
Olivia has four digits passcode.
The following steps can be used in order to determine Olivia’s passcode:
Step 1 - Let Olivia's passcode be 'wxyz'.
Step 2 - The sum of all the digits is given by the equation:
w + x + y + z = 21
Step 3 - The linear equation that represents the situation "The second digit from the left is three times the first (left-most) digit" is given by:
x = 3w
Step 4 - Now, use the hit and trial method first put (w = 1) and check all the given conditions. If w = 1 then x = 3 and but the third condition that is the last (right-most) two digits is three times the second digit from the left is not satisfied.
Step 5 - Now, put (w = 3) and check all the given conditions. If w = 3 then x = 9 and the last two digits become 2 and 7. And the sum of all the digits is equal to 21.
Step 6 - From the above steps, it can be concluded that the passcode is 3927.

The principal is 2200.00 and the rate of interest is 7% what is the final account balance after two years
Answer:
2508
Step-by-step explanation:
We are given that
Principal ,P=2200
Rate of interest, r=7%
Time, t=2 year
We have to find the final account balance after two years.
[tex]S.I=\frac{P\times r\times t}{100}[/tex]
Using the formula
[tex]S.I=\frac{2200\times 7\times 2}{100}=308[/tex]
Amount=P+S.I
Amount=2200+308
Amount=2508
Hence, the final account balance after two years=2508
The cost of manufacturing a printer is $35. The retailer has a markup of 150%. What is the selling
price of the printer?
Answer:
$87.50
Step-by-step explanation:
35 is the original price. we are increasing it by 150% i like to break it up
100 percent increase would just be adding another 35 to it. so 35+35=70
then we have a 50% increase 35/2=17.50
70+17.50=87.50
