The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
4 cm
12 cm
A = 10 cm
Area =
cm2
Answers
Answer:
90 cm²
Step-by-step explanation:
Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.
Let the area of the other triangle be x. Therefore:
[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]
[tex] \frac{10}{x} = \frac{16}{144} [/tex]
Cross multiply
[tex] 10*144 = 16*x [/tex]
[tex] 1440 = 16x [/tex]
Divide both sides by 16
90 = x
Area of the other polygon = 90 cm²

Samantha says the fraction of the group of customers who ordered raspberry topping is 1/2. Explain why samantha is correct.
Answers
Answer and explanation:
Yes Samantha is correct. Samantha is correct because a fraction 1/2 of customers who ordered raspberry toppings refers to half of the total number of customers. A fraction 1/2 is 50 percent or 50/100 of the population of customers, therefore meaning that 50% or half of the total number of group of customers ordered raspberry toppings

A cyclist travels 5 miles each way on a bike path. Travel in one direction is with a 4 mile per hour wind and travel back is against a 4 mile per hour wind. Part A: Write and simplify an equation for the amount of time t in hours it will take the cyclist to make the trip. Part B: What is the cyclist's total travel time, if she travels an average of 6 miles per hour without the wind?
Answers
Answer:
a. 10v/(v² - 16) b. 3 hours
Step-by-step explanation:
a. Write and simplify an equation for the amount of time t in hours it will take the cyclist to make the trip.
Let v be the speed of the cyclist without the wind. The speed of the cyclist with the 4 mile per hour wind in the direction of the wind is v' = v + 4. Since the distance travelled is 5 miles, and time, t = distance/speed, the time it takes to make this trip is t' = 5/(v + 4)
Let v be the speed of the cyclist. The speed of the cyclist with the 4 mile per hour wind against the direction of the wind is v" = v - 4. Since the distance travelled is 5 miles, and time, t = distance/speed, the time it takes to make this trip is t" = 5/(v - 4).
So, the total travel time, T = t' + t"
= 5/(v + 4) + 5/(v - 4)
= [5(v - 4) + 5(v + 4)]/[(v + 4)(v - 4)]
= [5v - 20 + 5v + 20)]/(v² - 4²)
= 10v/(v² - 16)
b. What is the cyclist's total travel time, if she travels an average of 6 miles per hour without the wind?
If v = 6 miles per hour, then
T = 10v/(v² - 16)
= 10(6)/(6² - 16)
= 60/(36 - 16)
= 60/20

Lena told her mother that the jeans that she bought were on sale for 10 percent off and she had saved $8.25 on them.
Answers
Answer:
$82.5
Step-by-step explanation:
Step one:
Given that the percent of which is 10% amount to $8.25
We can estimate the of the Jeans as
Step two
Let the cost be x
10 percent of x= 8.25
10/100*x=8.25
0.1x=8.25
Divide both sides by 0.1 to get the value of x
x=8.25/0.1
x=$82.5
The cost of the jeans is

since there is 2 negatives and (-)/ (-) means your answer is positve
to divide by a fraction multiply by the reciprocal of that fraction.

reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.

Jan spends part of her year as a member of a gym. She then finds a better deal at another gym, so she cancels her membership with the first gym after x months and spends the rest of the year, y months, with the second gym. The membership to the first gym costs $85 per month, while the membership for the second gym costs $50 per month. If she ended up spending a total of $705 over the course of the year, how much time did she spend at each gym?
Answers
Answer:
Jan spent 3 months at the first gym and 9 months at the second gym.
Step-by-step explanation:
Given that:
1 year = 12 months
x = months at gym one
y = months at other gym
According to given statement;
x+y=12 Eqn 1
85x+50y=705 Eqn 2
Multiplying Eqn 1 by 50
50(x+y=12)
50x+50y=600 Eqn 3
Subtracting Eqn 3 from Eqn 2
(85x+50y)-(50x+50y)=705-600
85x+50y-50x-50y=105
35x=105
Dividing both sides by 35
[tex]\frac{35x}{35}=\frac{105}{35}\\x=3[/tex]
Putting x=3 in Eqn 1
3+y=12
y=12-3
y=9
Hence,
Jan spent 3 months at the first gym and 9 months at the second gym.

Answers
Answer:
the answer is D. 10
Step-by-step explanation:
you get 3x -4 = 2x +6
you then subtract 2x from 3x and 2x
you get 1x - 4= 6
add 4 to both sides and you get
1x = 10 which is the same as x = 10
Answer:
x = 18
Step-by-step explanation:
3(x-4) = 2x+6
3x-12 = 2x +6
Add 12 to the -12 and the 6, giving you...
3x = 2x + 18
subtract 2 from the 3 and the 2, giving you...
1x = 18
divide the 1 and the 18 by 1, giving you...
x = 18

Answer:
C. 58.18 mph
Step-by-step explanation:
Answer:
C. 58.18
Step-by-step explanation:
The average speed means we will do miles per hour (mph). So if there are 640 miles for 11 hours the fraction would look like this:
640/11
We want to find the value for 1 hour so we need the bottom number(denominator) to be 1
Therefore we divide by 11 on the numerator and denominator by 11
58.181818(repeating)/1
This means we travel 58.181818... miles per hour.
If we round to the hundredths place we get 58.18 or option C.
Keep in mind that we can do this in ratio form and still get the same answer:
miles: hours
640:11
58.181818:1
