What is the value of x?

Mathematics
1 answer:
Orlov [11]3 years ago
5 0

Answer:

x = 24.5

Step-by-step explanation:

There are two similar triangles. In similar triangles the sides are in proportion.

Let's name big triangle as triangle 1 and small triangle as triangle 2.

The sides of the big triangle:

27 as base and the longest side (x + 7)

The sides of the small triangle:

base = 27 - 6 = 21

longest side = x

We need to find the value of x using proportion.

27/21 = (x + 7)/ x

By cross multiplying, we get

27(x) = 21(x + 7)

27x = 21x + 147

27x - 21x = 147

6x = 147

Dividing both sides by 6, we get

x = 147/6

x = 24.5

The value of x = 24.5

Hope you will understand the concept.

Thank you.

QUESTION 7.
Elan Coil [88]

The probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.

Given that based on a poll, 60% of adults believe in reincarnation, to determine, assuming that 5 adults are randomly selected, what is the probability that exactly 4 of the selected adults believe in reincarnation, and what is the probability that all of the selected adults believe in reincarnation, the following calculations must be performed:

  • 0.6 x 0.6 x 0.6 x 0.6 x 0.4 = X
  • 0.36 x 0.36 x 0.4 = X
  • 0.1296 x 0.4 = X
  • 0.05184 = X
  • 0.05184 x 100 = 5.184

  • 0.6 x 0.6 x 0.6 x 0.6 x 0.6 = X
  • 0.36 x 0.36 x 0.6 = X
  • 0.1296 x 0.6 = X
  • 0.07776 = X
  • 0.07776 x 100 = 7.776

Therefore, the probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.
