Answer:
Two polygons are similar with factor k.
=> The ratio between the area of two polygons: r = k^2
=> Here, the area of polygon B is larger than polygon A: 5^2 = 25 times
Hope this helps!
:)
Answer:
Area of polygon B is larger than the area of Polygon A by 25 times.
Step-by-step explanation:
The simplest way of finding this would be to draw a rough image of polygon A and B.
Let's say you drew Polygon A and B as rectangles. Since the scale factor is 5, the dimensions of the sides of polygon B would be 5 times as that of the dimensions of polygon A.
if you label the dimensions of Polygon A as length 2cm and width as 1cm, its area would be 2 square centimetres.
now keeping the scale factor of 5 in mind, multiply the length and the width by 5. you will get the length of polygon B as 10cm and width as 5cm. the area of polygon B becomes 50 square centimetres.
once you have done this, you will realise that the area of polygon B is 25 times the area of polygon A.
Hope this helped:)

1/3( 5x - 9) = 2( 1/3x + 6) what is x?
Answers
Answer:
x = 9
Step-by-step explanation:
→Distribute the [tex]\frac{1}{3}[/tex] to (5x - 9), and the 2 to [tex](\frac{1}{3} x + 6)[/tex]:
[tex]\frac{1}{3}[/tex](5x - 9) = 2( [tex]\frac{1}{3}x[/tex] + 6)
[tex]\frac{5}{3}x[/tex] + 3 = [tex]\frac{2}{3}x[/tex]+ 12
→Subtract [tex]\frac{2}{3}x[/tex] from both sides:
x + 3 = 12
→Subtract 3 from both sides:
x = 9
The value of x from the given equation is 6.
The given equation is 1/3 (5x - 9) = 2(1/3 x + 6).
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 5x/3 - 9/3 = 2x/3 +6/2
5x/3 -3 = 2x/3 +3
5x/3 -2x/3 =3+3
(5x-2x)/3 = 6
3x/3 = 6
x = 6
Therefore, the value of x from the given equation is 6.

Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once. Write about what additional information you would need to create a two-variable equation for the scenario. What kind of problem could you solve with your equation?
Answers
Answer:
You would need to know how much money she spent and how much she had left.
Step-by-step explanation:
With this, you could find out how much money she had in total.
Sample Response:
To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

A study shows that 35% of the fish caught in a local lake had high levels of mercury. Suppose that 10 fish were caught from this lake. Find, to the nearest tenth of a percent, the probability that at least 6 of the 10 fish caught did not contain high levels of mercury.
Answers
Answer:
0.985
Step-by-step explanation:
Given: 35% of the fish caught in a local lake had high levels of mercury.
To find: probability that at least 6 of the 10 fish caught did not contain high levels of mercury
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favourable outcomes/Total number of outcomes
Let A denotes the event that the fish caught in a local lake had high levels of mercury.
As 35% of the fish caught in a local lake had high levels of mercury,
[tex]P(A)=0.35[/tex]
Probability that at least 6 of the 10 fish caught did not contain high levels of mercury = 1 - probability that 4 of the 10 fish caught contain high levels of mercury = [tex]1-(0.35)^4=1-0.015=0.985[/tex]

The weights of the cars passing over a bridge have a mean 3,550 pounds and standard deviation of 870 pounds. Assume that the weights of the cars passing over the bridge are normally distributed. Use the empirical rule to estimate the percentage of cars over the bridge whose weights are between 1810 and 4420 lbs.
a. 13.5%
b. 81.5%
c. 68%
d. 95%
Answers
Mean = 3550
SD = 870
Find P(1810 <x<4420)
z = x -mean / sd
= (1810 - 3550 / 870) < z< (4420 - 3550 / 870)
= -2 <z< 1
Using the -z table -2 = 0.0228 and 1 = 0.8413
Subtract: 0.8413 - 0.0228 = 0.8185 x 100 = 81.85%

Tyron made 60 cakes. He gave 1/6 of the 60 cakes to Lilly. What fraction of the cakes does he have left?
Answers
Answer:

Step-by-step explanation:
The question isn't fully attached as stated by the person who submitted it.
The fraction of the cakes he has left is ( 5 / 6 ). The remaining number of cakes is 50.
What is a fraction?Expression in maths is defined as the collection of numbers, variables, and functions using signs like addition, subtraction, multiplication and division.
The fraction is calculated as:-
The remaining fraction = 1 - ( 1 / 6 )
= ( 6 - 1 ) / 6
= 5 / 6
The remaining number of cakes,
Remaining number = 60 x ( 5 / 6 )
Remaining number = 50
Hence, the remaining number of cakes is 50.

Answers
Answer:
3/70
Step-by-step explanation:
3 orange,6 pink , 1 yellow , and 5 red = 15
P(pink) = number of pink/ total = 6/15 = 3/5
Then without putting it back
3 orange,5 pink , 1 yellow , and 5 red = 14
P(yellow) = number of yellow/ total = 1/14
P(pink, no replacement, yellow) = 3/5*1/14 = 3/70
