Answer:
8:4
Step-by-step explanation:
Given that,
The ratio of the areas of similar polygons is 64: 16, A₁:A₂=64: 16
We need to find the ratio of their sides. For similar polygons, the ratio of the area is proportional to the square of the ratio of their corresponding sides.
Let sides are x₁ and x₂. So,
[tex]\dfrac{A_1}{A_2}=(\dfrac{x_1}{x_2})^2\\\\\dfrac{x_1}{x_2}=\sqrt{\dfrac{A_1}{A_2}} \\\\=\sqrt{\dfrac{64}{16}}\\\\=\dfrac{8}{4}[/tex]
So, the required ratio is 8:4.

A CD player and a Nike sneaker together cost $ 444. The price of the CD player is double the price of the sneaker. How much do they each cost ?
Answer:
The CD player costs $296 and the Nike sneaker costs $148.
Step-by-step explanation:
From the information given, you know that a CD player and a Nike sneaker together cost $ 444, which can be expressed as:
x+y=444, where
x is the cost of the CD player
y is the cost of the Nike sneaker
Also, you know that the price of the CD player is double the price of the sneaker, which can be expressed as:
x=2y
You can replace this formula x=2y in the first one and solve for y:
2y+y=444
3y=444
y=444/3
y=148
Finally, you can replace the value of y in x=2y to find the value of x:
x=2(148)
x=296
According to this, the answer is that the CD player costs $296 and the Nike sneaker costs $148.

6x+18y=18 find y and z
6x + 18y = 18. Let us take x = 0
6(0) + 18y = 18
0 + 18y = 18
18y = 18
y = 18/18
y = 1
(0, 1) [x = 0, y = 1]
6x + 18y = 18. Let us take y = 0
6x + 18(0) = 18
6x + 0 = 18
6x = 18
x = 18/6
x = 3
(3, 0) [x = 3, y =0]
Infinite solutions can be found for x and y

4x-2y = 2
3x-2y=-19
Help
Answer:
{x,y}={21,41}
Step-by-step explanation:
Step by Step Solution:
More Icon
System of Linear Equations entered :
[1] 4x - 2y = 2
[2] 3x - 2y = -19
Graphic Representation of the Equations :
-2y + 4x = 2 -2y + 3x = -19
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 3x = 2y - 19
[2] x = 2y/3 - 19/3
// Plug this in for variable x in equation [1]
[1] 4•(2y/3-19/3) - 2y = 2
[1] 2y/3 = 82/3
[1] 2y = 82
// Solve equation [1] for the variable y
[1] 2y = 82
[1] y = 41
// By now we know this much :
x = 2y/3-19/3
y = 41
// Use the y value to solve for x
x = (2/3)(41)-19/3 = 21
Solution :
{x,y} = {21,41}
Answer: {x,y}={21,41}

A fruit punch recipe call for 30 cups of orange juice and 18 cups of pineapple juice. If you only have 1 cup of orange juice, how many cups of pineapple should you use.
Answer:
You should use 0.6 cups of pineapple juice if you only have 1 cup of orange juice.
Step-by-step explanation:
With the information provided about the recipe, you can use a rule of three to find the cups of pineapple you should use if you only have 1 cup of orange juice given that the recipe calls for 30 cups of orange juice and 18 cups of pineapple juice:
30 cups of orange juice → 18 cups of pineapple juice
1 cup of orange juice → x
x=(1*18)/30=0.6 cups of pineapple juice
According to this, the answer is that you should use 0.6 cups of pineapple juice if you only have 1 cup of orange juice.
The number of necklaces Lilly can make varies directly with the amount of time she spends making the necklaces. She can make 6 necklaces in ⅖ hour. How many necklaces can Lilly make in 5 hours?
Answer:
75
Step-by-step explanation:
Number of necklace= k × amount of time spent
6= k × 2/5
K = 6÷2/5
K= 6×5/2
K= 15
Therefore the number of necklace made in 5 hours can be calculated as follows
15 = number of necklace ÷ 5
Number of necklace = 15 ×5
Number of necklace = 75
Answer:
75

Solve the proportion 4/5 equals X over 15
y=−x/3+4. WHOEVER ANSWERS GETS BRAINLIEST!
Answer:
Step-by-step explanation:
put the y intercept at 4. then go down 1 and right three, down one, then right three. go back to the y intercept and then go up one and left three, up one and left three
to answer this you should plot a point at (0,4). That is the y intercept as you can see on the equation +4 is at the end. Since the slope is -1/3, go 1 unit left and 3 up from the y intercept. those are your two points and draw a straight line though.

.MARY WAS TOLD TO RUN AROUND THE TRACK 5 TIMES BY HER COACH. ONCE AROUND THE TRACK IS 5/6 OF A MILE. MARY WAS ONLY ABLE TO RUN AROUND THE TRACK 4 1/3 TIMES. HOW MANY MILES TOTAL DID MARY RUN?
Answer:
3.61 miles
Step-by-step explanation:
Given that:
Length of track = 5/6 of a mile
Number times Mary was able to run around the track = 4 1/3 times
Total miles ran by Mary :
(Equivalent mile of the track * number of times Mary ran around the track)
5/6 of a mile * 4 1/3 times
5/6 * 13/3
= 65 / 18
= 3.611111 miles
Hence, total Number of miles ran by Mary is 3.61 miles
X+y=8
Y=3x
Solve with substitution
Correct answer gets Brainliest!!
Answer:
x=2, y = 6
Step-by-step explanation:
We see that y = 3x so we can substitute the y in x + y = 8.
x + 3x = 8.
Combine like numbers:
4x = 8.
Divide both sides by 4.
x = 2
Now plug in x to find y
2 + y = 8
Subtract 2 from both sides.
y = 6

Explain how can you use place value to compare 1.679 and 1.697.
Thanks!
Answer:
Well, you look at each individual place value.
1.679 and 1.697
Compare 1 to 1. They are the same. Move on.
Compare 0.6 to 0.6. They are the same. Move on
Compare 0.07 and 0.09. They are not the same. 0.07 is less than 0.09
Therefore 1.679 < 1.697

the side lengths of a triangle are 6, 8 and 12 is this a right triangle
Answer:
No it is not a right triangle.
Step-by-step explanation:
We calculate the squares of the two littlest sides and add them :
6² + 8² = 36 + 64 = 100
We now calculate the square of the biggest side :
12² = 144
They are not equal, and thus, the triangle is not a right triangle.
Hope this helped! If so, plz mark brainliest.
Answer:
No, Because 6^2 + 8^2 = 12^2

Given: F=(0,1),(2,4),(4,6),(6,8) and g=(2,5),(4,7),(5,8),(6,9),(7,5) (fxg)(2)
Answer:
(F-G)(x) = -1
Step-by-step explanation:
The notation (F - G)(x) means to subtract each function when x = 6. According to the sets when x = 6 then F is (6,8) and G is (6,9). To subtract the functions, subtract their output values. (F-G)(x) = 8 - 9 = -1.
