B. Area equals (for a square) two side lengths multiplied by one another, so 5x5=25

In ΔBCD, the measure of ∠D=90°, CB = 25, BD = 7, and DC = 24. What is the value of the sine of ∠C to the nearest hundredth?

Answers

Answer: The value of the sine of ∠C is 0.28.

Step-by-step explanation:

Let's draw a triangle again (see the picture below).

Remember SOHCAHTOA? It's:

-sin = opposite/hypotenuse

-cos = adjacent/hypotenuse

-tan = opposite/adjacent.

We need to use sin in here.

The sin of C is (7)/(25), which in a calculator, gives 0.28

The table shows a relationship between and y-values.which statement describes the pattern created by the values?
» Each y value is determined by
multiplying each x value by 3, so the
pattern is multiplicative
» Each y value is determined by adding
4 to each x value, so the pattern is
additive
» Each y-value is determined by adding
2 to each value, so the pattern is
additive
» Each y value is determined by
multiplying each value by 2, so the
pattern is multiplicative

What is the height of a
triangle with area 893 square
inches and base 38 inches?

Answers

Here is the answer.

Answer:

47

Step-by-step explanation:

Start by drawing the figure and labeling it with the given information. We are looking for the height of a triangle. The formula for the area of a triangle is A=12bh, where b is the length of the base and h is the height of the triangle. Substituting in the given information and solving for h, we find

A8938931947=12bh=12(38)(h)=h=h

The height is 47 inches.

Kevin has 65 feet of fencing. He wants to use all the fencing to create a rectangular fence around his pool. The equation 2L + 2W = 65, where l is the length of the fence and w is the width. If Kevin makes the length of the fence 13 feet long, how wide should he make it?

Answers

19.5 feet long because it’s says 2L so the length he puts it at is 13 feet so you times that by 2 and get 26. Then take 65 minus 26 and you get 39, then take 39 divided by 2 and get 19.5 I think that’s the answer that’s what I would do
