Answer:

we conclude that Kiera got the right 63 questions.

Step-by-step explanation:

Total questions = 90

The percentage of correct question = 70%

Using the formula

The number of correct questions = 70% of 90

                                                         = [70/100] × 90

                                                          = 0.7 × 90

                                                           = 63

Therefore, we conclude that Kiera got the right 63 questions.

dybincka [34]

If your solving for x, you need to isolate/get the variable "x" by itself in the inequality:

-24 ≤ 3x - 9        First add 9 on both sides

-24 + 9 ≤ 3x - 9 + 9

-15 ≤ 3x        Then divide 3 on both sides to get "x" by itself

\frac{-15}{3} \leq \frac{3x}{3}

-5 ≤ x                  [or  x ≥ -5 if you prefer "x" to be on the left side]

Guys help me pls I need it immediately
julsineya [31]

Answer:

Hey there!

First, we want to find the side length of the large triangle.

1/2bh=y cm^2

bh=2y cm^2

Since b and h are the same here, we have b^2= 2y, b=\sqrt{2y}.

And we have FC=\frac{\sqrt{2y} }{2}.

Area of shaded triangle: \frac{1}{2} (\frac{\sqrt{2y} }{2})(\frac{\sqrt{2y} }{2}).

This is equal to: \frac{1}{2}(\frac{2y}{4}), or y/4.

Let me know if this helps :)
