Answer:

Option C is correct

11.1 inches

Step-by-step explanation:

Area of the square(A) is given by:

A = s^2

where,

s is the length of one side of the square.

As per the statement:

Avi’s dining room measures 124 square feet and is in the shape of a square.

⇒A = 124 square feet.

By definition we have;

124 = s^2

or

s^2 = 124

⇒s = \sqrt{124} = 11.1355287 inches

Therefore, 11.1 inches is the best estimate of the length of one side of the room, to the nearest tenth of a foot

The answer is 11.13 so in nearest tenth it would be 11.1

Find the value of c so that (x+2) is a factor of the polynomial p(x). p(x)=4x^3+cx^2+x+2
Wittaler [7]

Answer:

c = 8

Step-by-step explanation:

Use synthetic division here; it's the fastest approach.

Given that (x + 2) is a factor, take -2 and use this as the divisor in synthetic division:

-2     4         c                1           2

                  -8    (-2c+ 16)      (4c-34)

       ---------------------------------------------

         4    (c - 8)   (-2c + 17)     4c - 32

The remainder, 4c - 32, must equal zero if (x + 2) is a factor.

Then 4c - 32 = 0, and c = 8

Somebody help #9 geometry
IrinaK [193]

Answer:

41.1units^2

Step-by-step explanation:

A=\frac{h_{b}b }{2} \\=\frac{8*4}{2} \\=16units^2(triangle)

A=\frac{\pi r^2}{2}\\\frac{\pi 4^2}{2}\\=25.13units^2(semicircle)

Add both together

16+25.13\\=41.13units^2

Given triangle DEF where ∠D = (7b +1)∘, ∠E = (2b + 1)∘, and ∠F = ( b + 8)∘. What is the measure of ∠E?
____ [38]
<h3>Answer:  35 (choice C)</h3>

=============================================

Explanation:

For any triangle, the three interior angles always add to 180.

D+E+F = 180

(7b+1) + (2b+1) + (b+8) = 180

(7b+2b+b) + (1+1+8) = 180

10b+10 = 180

10b = 180-10

10b = 170

b = 170/10

b = 17

Use this value of b to find the three angle measures

  • D = 7b+1 = 7*17+1 = 119+1 = 120
  • E = 2b+1 = 2*17+1 = 34+1 = 35 degrees
  • F = b+8 = 17+8 = 25

As a check,

D+E+F = 120+35+25 = 120+60 = 180

which helps confirm the correct answers.
