5a+2a(5+—b)= please i need help

Answers

Answer 1

Answer: 5a + 2a(5 + (-b)) = 5a + 2a(5 - b)

Use the distributive property which states a(b+c) = ab + ac

5a + 10a - 2ab

Simplify like terms

15a - 2ab

I will award brainliest!!In the given figure, the reflex angle ∠DOB has measure of 3.5y while the measure of ∠AOD is y. Find the measure of the non-reflex ∠DOB in degrees.

Answers

Answer:

In the given figure:

The reflex angle $\angle DOB=3y$ and $\angle AOD = y$

$\angle COB = \angle AOD = y$ [By vertical angle theorem]

From the given we can say that:

$\angle AOC$ and $\angle COB$ are supplementary angles.

Supplementary angles states that the two measure are add up to 180 degree.

⇒ $\angle AOC +\angle COB = 180^(\circ)$ .....[1]

then; the reflex angle DOB is:

$\angle DOB = \angle AOD + \angle AOC + \angle COB$

Substitute the given values we get;

$3.5y=y+180^(\circ)$

Subtract y from both sides we get;

$2.5 y = 180^(\circ)$

Divide both sides by 2.5 we get;

$y = 72^(\circ)$

$\angle DOB = 3y = 3.5(72) =252^(\circ)$

We have to find the non reflex $\angle DOB$

Non reflex angle DOB is;

$\angle DOB = 360^(\circ)-252^(\circ) = 108^(\circ)$

Therefore, the non-reflex angle DOB is 108 degree.

Answer: 252 degrees

Step-by-step explanation: so we know that a half circle is 180.

What is 37/4 as a percent

Answers

$(37)/(4)$ × 100
925%

because $(37)/(4)$ = 9.25

9.25 × 100= 925%

the caculater says 9.25 see all you really have to do is divide the 37 into the 4 witch will lead you to the 9 then Carrie over again then leave you with the .25 with would all sum up to 9.25 .
