A person jogs 4 kilometers in 32 minutes, the 2 kilometers in 22 minutes, and finally 1 kilometer in 16 minutes. What is the jogger's average speed in kilometers per minute?
Answer:
0.1km per minStep-by-step explanation:
what is average speed:
"The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time."
step one:
given data
Distances Time
4km 32min
2km 22min
1km 16min
the total distance covered is
4+2+1= 7km
the total time taken = 32+22+16=70min
the average speed= distance/time
average speed= 7/70= 0.1km per min

8x+5x= 1300
what is x
Answer:
x = 100
Step-by-step explanation:
Original equation:
8x + 5x = 1300
Combine like factors
13x = 1300
Divide both sides by 13
x = 100

Tiffany buys a basket of watermelons on sale for \$9$9dollar sign, 9 before tax. The sales tax is 9\%9%9, percent.
What is the total price Tiffany pays for the basket of watermelons?
\$\$ dollar sign, space
Answer:
Tiffany pays a total price of $9.81 for the basket of watermelons
Step-by-step explanation:
Percentages
To increase a certain amount by a given percentage, we can first calculate the increasing amount and then add it to the original amount.
If the price of the basket of watermelons was $9 before tax, and the sales tax is 9%, we first calculate the tax amount to pay:
$9 * 9 / 100 = $0.81
Now we add it to $9 to get the total price paid by Tiffany:
Total price = $9 + $0.81 = $9.81
Tiffany pays a total price of $9.81 for the basket of watermelons
Answer:
9.81 it was confirmed :)

Manuel and Felicia are comparing how much
money they have
• Manuel has $250.
• He saves $150 per week,
• Felicia has $1,650.
• She spends $200 per week.
• Let x = the number of weeks
• Let y = the amount of money at the end
of the week.
Which system of equations represents this
situation?
Answer:
y = 250 + 150xy = 1650 - 200xStep-by-step explanation:
Equation for Manuel:
y = 250 + 150xEquation for Felicia:
y = 1650 - 200xSolving we get:
250 + 150x = 1650 - 200x150x + 200x = 1650 - 250350x = 1400x = 1400/350x = 4 weeksand
y = 250 + 150*4 = 250 + 600 = $850After 4 weeks Manuel and Felicia will have equal amount of money- $850

Mary-Ann has $28, which is 2 1 3 as much money as Lola has. How much money does Lola have? find the number
Answer:
Lola has $12
Step-by-step explanation:
To find how much money Lola has, we need to divide $28 by 2 1/3:
28 ÷ 2[tex]\frac{1}{3}[/tex] = [tex]\frac{28}{1}[/tex] × [tex]\frac{3}{7}[/tex] = [tex]\frac{12}{1}[/tex] = 12
Hope this helps! :)
Answer:
$12
Step-by-step explanation:
Lola has x.
Mary-Ann has 2 1/3 times what Lola has. Mary-Ann has $28
2 1/3 * x = 28
Change 2 1/3 into a fraction.
(7/3)x = 28
Multiply both sides by the reciprocal of 7/3 which is 3/7.
(3/7) * (7/3)x = (3/7) * 28
x = 12
Answer: Lola has $12.
Kenny had a total of 140 minutes to read, do homework, and play video games he spent x minutes reading, he spent 2(x+5) minutes doing homework, he spent 25 minutes playing video games how many minutes did Kenny spend reading
Answer:
He spent 52.5 minutes reading.
Step-by-step explanation:
The equation from the word problem is 2(x+5)+25=140. Distribute 2 to the parentheses and get 2x+10+25=140. Combine like terms to get 2x+35=140. Subtract 35 from both sides and get 2x=105. Divide both sides by 2 and your final answer is x=52.5

Which set of transformations is needed to graph f(x) = -0.1cos(x) - 4 from the parent cosine function?
reflection across the y-axis, vertical compression by a factor of 0.1, vertical translation 4 units up
reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down
vertical stretching by a factor of 0.1, vertical translation 4 units down, reflection across the y-axis
vertical stretching by a factor of 0.1, vertical translation 4 units up, reflection across the x-axis
Answer:
The correct option is;
Reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down
Step-by-step explanation:
The given function is f(x) = -0.1·cos(x) - 4
The parent cosine function is cos(x)
Therefore, f(x) = -0.1·cos(x) - 4 can be obtained from the parent cosine function as follows;
The negative sign in the function gives a reflection across the x-axis
The 0.1 factor of the cosine function gives a compression of 0.1
The constant -4, gives a vertical translation 4 units down
Therefore, the correct option is a reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down.
Answer:
✔ vertical compression by a factor of 0.5
reflection across the y-axis
✔ vertical translation 3 units down
vertical stretch by a factor of 0.5
✔ reflection across the x-axis
vertical translation 3 units up
vertical translation 0.5 units down

Monday's high temperature in Denver, Colorado was 25°F. The low temperature was
-4° F. What was the difference between the high and low temperatures?
Answer:
The difference between the high and low temperatures is 29°F
Step-by-step explanation:
Subtraction
The high temperature in Denver, Colorado was 25°F on Monday.
The low temperature was -4°F in the same place.
We are required to find the difference between the high and low temperatures.
We need to subtract 25 and -4:
Difference = 25°F - (-4°F)
Note we change the sign of the subtraction multiplying (-1) by (-1);
Difference = 25°F + 4°F
Difference = 29°F
The difference between the high and low temperatures is 29°F
Kedar earns a monthly salary of $2,200 plus a 3.75% commision on the amount of his sales at men's clothing store. What would he earn this month if he sold $4,500 in clothing?
Answer:
$2368.75
Step-by-step explanation:
Kedar earns a monthly salary of $2200 and a commission of 3.75%
He sold $4500 this month
The first step is to calculate his commission for this month
His commission can be calculated as follows
= 4500 × 3.75/100
= 4500 × 0.0375
= 168.75
Therefore yr amount earned this month can be calculated as follows
= 2200 + 168.75
= $2368.75

4x-7y=3
x-7y=-15
Answer:
x = 6, y =3
Step-by-step explanation:
4x-7y=3
x-7y=-15
Multiply the first equation by -1
-4x+7y=-3
Then add this to the second equation to eliminate y
-4x+7y=-3
x-7y=-15
------------------
-3x +0y = -18
-3x = -18
Divide by -3
-3x/-3 = -18/-3
x = 6
Now find y
x -7y = -15
6 -7y = -15
Subtract 6 from each side
6-7y-6 = -15-6
-7y = -21
Divide by -7
-7y/-7 = -21/-7
y =3
