Solve for X. The Triangles in each pair are similar

Mathematics
1 answer:
Klio2033 [76]3 years ago
5 0

Answer:

x = 7

Step-by-step explanation:

In this question, we need to find what the value of x is.

To do so, we need to find the value of the change of the triangle, since the triangles are basically the same

We know to get from 18 to 27, we would need to multiply 18 by 1.5.

This means that the triangle "BCD" is increasing from 1.5 to get "JKL"

With this knowledge, we also know that side CB, 10, needs to increase by 1.5

When you multiply 10 by 1.5, you get 15.

The triangle side "JK" is the same side as "CB", so we need to find what makes the value of 15 for the "JK" side.

To do this, solve 3x-6 for 15.

3x - 6 = 15

Add 6 to both sides.

3x = 21

Divide both sides by 3

x = 7

The x-variable would be 7.

Step-by-step explanation:

the sum of the unknown angle and 110° is 180 °

If it took 6 hours to clean 12 houses, how many houses could be cleaned in 11 hours?
nata0808 [166]

22 houses can be cleaned in 11 hours.

Step-by-step explanation:

It is given that;

6 hours = 12 houses cleaned

1 hour = \frac{12}{6}\ houses\ cleaned\\

1 hour = 2 houses cleaned

In 1 hour, 2 houses can be cleaned, therefore,

11 hours = Time*houses cleaned in one hour

11 hours = 11*2 =22 houses cleaned

22 houses can be cleaned in 11 hours.

That would  a set of 5 numbers in ascending order with  4 being the middle one and the other 4 being the highest possible So it is

2, 3, 4, 9, 10

Mean is 28/5  = 5.6 answer

( I am assuming that each number is different)

Of duplicates is allowed then its 4 4 4 10 10  whose mean is 6.4

If g(x) = 3x + 2 and h(x) = 9x2 + 12x + 6, find a function f such that f ○ g = h
Virty [35]
F(g(x)) = f(3x+2) = h(x)=9x^2+12x + 6

Note that (3x+2)^2 = 9x^2 + 12x + 4, which is almost, but not quite, equal to h(x).

Let's experiment.  What if f(x) = x^2 + 2?

Then f(3x+2) = (3x+2)^2 + 2 = 9x^2 + 12x + 4 + 2 = 9x^2 + 12x + 6, which is the same as the given h(x).

Thus, f(x) is x^2 + 2.
