Pls tell me some answers for this
devlian [24]

Answer:

∠B ≈ 56.25°

Step-by-step explanation:

Since the triangle is right use the cosine ratio to solve for B

cosB = \frac{adjacent}{hypotenuse} = \frac{BC}{AB} = \frac{5}{9}, thus

B = cos^{-1}(\frac{5}{9} ) ≈ 56.25°

What are the solutions 2x^2 +7x=4
elena55 [62]
So your equation is 2x^{2} +7x = 4. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now 4x + 7x = 4.
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's 11x = 4 right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be

0.36.

I hope I helped!

500=100(x-1)<br> Someone tell me step by step
Andre45 [30]
First, distribute the 100 to the (x-1) portion:
500 = 100x - 100

then, add 100 to both sides of your equation to get “x” alone on the right side:
500 + 100 = 100x - 100 + 100
600 = 100x

next, divide 100x by 100 and 600 by 100 to isolate a singular “x”:
600/100 = 100x/100
6 = x

therefore, x=6 is your solution

Mr. Lewis designed a circular walkway in
NARA [144]

Answer:

The diameter is equal to the circumference divided by the number pi

Step-by-step explanation:

we know that

The circumference of the circular walkway is equal to

C=\pi D

where

D is the diameter

we have

D=6\ ft

substitute

C=\pi (6)

C=6\pi\ ft

so

Divide the diameter by the circumference

\frac{D}{C}=\frac{6}{6\pi}

\frac{D}{C}=\frac{1}{\pi}

D=\frac{C}{\pi}

The diameter is equal to the circumference divided by the number pi
