NEED ANSWERS ASAP The two triangles are similar. What is the value of x?

Mathematics

Alexus [3.1K]2 years ago

If the two triangles are similar, then by definition we have that the quotient between two sides of a triangle is equal to the quotient between two sides of the second triangle.
 We have then:
 ((3x) / (4x + 2)) = ((20) / (28))
 Clearing:
 3x = (20/28) * (4x + 2)
 28 * 3x = (20) * (4x + 2)
 84x = 80x + 40
 84x-80x = 40
 4x = 40
 x = (40) / (4)
 x = 10
 answer
 The value of x is 10

So we're looking for 5% of the 350,000 which will be x

X. = 5
350000. 100
Cross multiply
100x=1750000
Divide by 100

Answer:

P = 47.1 units

Step-by-step explanation:

the perimeter of the pair of straight opposite sides is 11+11, or 22

now you have 2 semi-circles, which equals 1 full circle which, if we find the circumference to then we just add it to 22 to get the entire answer

Circumference of circle with diameter of 8:

C = 2πr

C = 2π(4)

C = 8π

C = 25.13

now add 22 + 25.13 to get 47.1 rounded to nearest tenths place

2000 is blank 10 times as much what is the answer and 2000 of 1/10
Molodets [167]
2,000 is 10 times as much as 200. To find the answer we can divide 2,000 by 10:

2,000 / 10 = 200

It means that 200 is also 1/10 of 2,000.

If you want to find out what 2,000 is 1/10 of, then just multiply it by 10:

2,000 * 10 = 20,000

2,000 is 1/10 of 20,000.
