Answer: c) choosing a consonant from the set {b, c, d, e, f}

Step-by-step explanation:

Since all of the choice sets have 5 values each, a 0.8 chance = 80% = \frac{4}{5}.

So find the set with 4 values that meet the criteria.

A: 5/5 = 1 = 100%

B: 1/5 = 0.2 = 20%

C: 4/5 = 0.8 = 80%

D: 0/5 = 0 = 0%

Can someone help me with this!
Doss [256]

Answer:

<u>Please read the answers below.</u>

Step-by-step explanation:

Let's recall that in a square all its sides are equal length and all the four internal angles measure 90 °

5. If LN = 46, then we have:

OM = <u>46</u> (Same length than LN)

PN = LN/2 = 46/2 = <u>23</u>

ON = √LN²/2 = √ 46²/2 = √ 2,116/2 = √ 1,058 = <u>32.53 (Rounding to two decimal places)</u>

MN = ON = <u>32.53</u>

6. m ∠EFG = <u>90°</u>

m ∠GDH = ∠GDH/2 = 90/2 =<u> 45°</u>

m ∠FEG = ∠DEF/2 = 90/2 =<u> 45°</u>

m ∠DHG = 180 - (∠GDH + ∠DGH) = 180 - (45 + 45)= 180 - 90 = <u>90</u>°

7. Solve for x

6x - 21 = ∠PQR/2

6x - 21 = 90/2

6x - 21 = 45

6x = 45 +21

6x = 66

<u>x = 11</u>

I have a square with a side of 5.25 in. There is a circle inside this square that is big enough to touch all four sides. What is
DENIUS [597]

Answer:

5.9125in^2

Step-by-step explanation:

Step one:

Given data

Dimension of square= 5.25 in

Area of sqaure= 5.25^2= 27.5625  in^2

We are told that the sides of the circle touch the sides of the square

hence the diameter of the circle is 5.25in

radius= 5.25/2= 2.625 in

Area of  circle= πr^2

Area of circle = 3.142*2.625^2

Area of circle=3.142*6.890625

Area of circle= 21.65 in^2

Step two:

The area that is not inside the circle

=Area of square-Area of circle

=27.5625- 21.65

=5.9125in^2
