8 0

Answer:

complement of 51 is 39

supplement of 54 is 126

Step-by-step explanation:

Complementary angles add to 90 degrees

51 + c = 90

Subtract 51 from each side

51-51 + c = 90-51

c = 39

The complement is 31

Supplementary angles add to 180 degrees

54 + s = 180

Subtract 54 from each side

54-54 + s = 180-54

s = 126

The supplement is 126

Answer:

176.625 sq.ft, 4.8 sq.ft

Step-by-step explanation:

Area of circle=πr^2 or πd^2/4
11. Given,
d=15 ft
Now,
Area=πd^2/4
3.14*15^2/4
176.625 ft^2
Therefore, the area approximation is 176.6 sq.ft
12.
Given,
d=3.5 ft
Now,
Area= πd^2/8
3.14*3.5^2/8
4.8 sq.ft
I got the answer by dividing the area of circle by 2 as semicircle is half of circle.

X=6<br> is a solution to the inequality x−5≤ 10<br><br> True or False?

vekshin1

Answer:

$\boxed{\sf{FALSE}}$

$\boxed{\sf{x\leq 15}}$

Step-by-step explanation:

Isolate the term of x from one side of the equation.

<h3>x-5≤10</h3>

<u>First, add by 5 from both sides.</u>

$\sf{x-5+5\leq10+5}$

<u>Solve.</u>

<u>Add the numbers from left to right.</u>

$\sf{10+5=15}$

$\Longrightarrow: \boxed{\sf{x\leq 15}}$

<u>Therefore, the solution is x≤15, which is our answer.</u>

I hope this helps you! Let me know if my answer is wrong or not.
