Which of the following values of r will result in a true statement when substituted into the given equation? -r + 5(r + 2) = -10
kramer

Answer:

Choice B is correct.

Explanation:

The given equation is -r+5(r+2)=-10

Put r=-5 into the above equation

-(-5)+5(-5+2)=-10

5+5(-3)=-10

5-15=-10

-10=-10

Right and left side of above equation is equal by putting r=-5 so it is true statement.

AngleB =<br> Round your answer to the nearest hundredth.<br> А<br> 5<br> ?<br> B<br> С<br> 4.
Zarrin [17]

Answer:

B=36.87

Step-by-step explanation:

As we are given the adjacent (a) side and the hypotenuse (h), we can use the cosine function to find the measure of angle B.

Recall that cos(B)=\frac{a}{h}

This means that in order to find B, we need to take the inverse of cosine

This gives us

B=cos^{-1} (\frac{4}{5} )

From a calculator, we find that the answer of this is

B=36.869

When this is rounded to the nearest hundredth, we get

B=36.87

QUICK I NEED MAJOR HELP !! WILL MARK BRAINLIEST
meriva

Answer:

y = 5 ft

Step-by-step explanation:

We are looking for y.

This is a right triangle, so we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

a = 12 and b = y   c = 13

12^2 + y^2 = 13^2

144 + y^2 =169

Subtract 144 from each side

144-144 +y^2 = 169-144

y^2 = 25

Take the square root of each side

sqrt(y^2) = sqrt(25)

y = 5
