Answer:

5.4ft²

Step-by-step explanation:

Area of yellow region

= area of square - area of circle

Area of square= side ×side

Area of circle= πr²

5ft is the length of a side of the square, as well as the diameter of the circle.

Diameter= 2 ×radius

Radius or circle, r

= 5 ÷2

= 2.5 ft

Area of yellow region

= (5 ×5) - π(2.5²)

= 25 -6.25π

= 5.4 ft² (to nearest tenth)

Step-by-step explanation:

Answer:

x > 12

Step-by-step explanation:

Step 1: Subtract 8 from both sides

[tex]\frac{1}{4}x[/tex] + 8 - 8 > 11 − 8

[tex]\frac{1}{4}x[/tex] > 3

Step 2: Multiply both sides by 4.

(4) ([tex]\frac{1}{4}x[/tex]) > (4) (3)

x > 12

The Answer is: C.120

Answer:

∠ RST = 120°

Step-by-step explanation:

∠ RST = ∠ RSU + ∠ UST , substitute values

6x + 12 = 78 + 3x - 12

6x + 12 = 3x + 66 ( subtract 3x from both sides )

3x + 12 = 66 ( subtract 12 from both sides )

3x = 54 ( divide both sides by 3 )

x = 18

Thus

∠ RST = 6x + 12 = 6(18) + 12 = 108 + 12 = 120°

Answer:

4.2

Step-by-step explanation:

Because 1/5 has to be converted into the 100 as the denominator and the number you are supposed to have for the numerator so it can be easier and 4 is the whole number so it doesnt need to be in the equation.

1/5

20= 20/100  so now all you have to do is make that a decimal since it hasnt got to 100 or past it and you have your answer

Angles in a transversal can be congruent either by theorems of corresponding and vertical angles.

The measure of the angles are:

[tex]\angle 1 = 97^o[/tex]

[tex]\angle 2 = 83[/tex]

[tex]\angle 3 = 66[/tex]

[tex]\angle 4 = 114^o[/tex]

[tex]\angle 5 = 83^o[/tex]

[tex]\angle 6 = 97^o[/tex]

[tex]\angle 7 = 114^o[/tex]

[tex]\angle 8 = 66^o[/tex]

[tex]\angle 9 = 97^o[/tex]

[tex]\angle 10 = 83[/tex]

[tex]\angle 11 = 66[/tex]

[tex]\angle 12 = 114^o[/tex]

[tex]\angle 13 = 83^o[/tex]

[tex]\angle 14 = 97^o[/tex]

[tex]\angle 15 = 114^o[/tex]

[tex]\angle 16 = 66^o[/tex]

Given that:

[tex]\angle 9 = 97^o[/tex]

[tex]\angle 12 = 114^o[/tex]

The following angles are congruent by theorem of vertical angles.

[tex]\angle 9[/tex] and [tex]\angle 14[/tex]

[tex]\angle 12[/tex] and [tex]\angle 15[/tex]

So, we have:

[tex]\angle 14 = 97^o[/tex]

[tex]\angle 15 = 114^o[/tex]

Apply the theorem of angles on a straight line, we have:

[tex]\angle 9 + \angle 10 = 180[/tex]

[tex]\angle 11 + \angle 12 = 180[/tex]

So, we have:

[tex]\angle 10 = 180 - 97[/tex]

[tex]\angle 10 = 83[/tex]

[tex]\angle 11 = 180 - 114[/tex]

[tex]\angle 11 = 66[/tex]

The following angles are congruent by theorem of vertical angles.

[tex]\angle 10[/tex] and [tex]\angle 13[/tex]

[tex]\angle 11[/tex] and [tex]\angle 16[/tex]

So, we have:

[tex]\angle 13 = 83^o[/tex]

[tex]\angle 16 = 66^o[/tex]

The following angles are congruent by theorem of corresponding angles.

[tex]\angle 9[/tex] and [tex]\angle 1[/tex]                 [tex]\angle 13[/tex] and [tex]\angle 5[/tex]                      [tex]\angle 10[/tex] and [tex]\angle 2[/tex]

[tex]\angle 14[/tex] and [tex]\angle 6[/tex]             [tex]\angle 11[/tex] and [tex]\angle 3[/tex]                     [tex]\angle 15[/tex] and [tex]\angle 7[/tex]

[tex]\angle 12[/tex] and [tex]\angle 4[/tex]               [tex]\angle 16[/tex] and [tex]\angle 8[/tex]

So, we have:

[tex]\angle 1 = 97^o[/tex]

[tex]\angle 4 = 114^o[/tex]

[tex]\angle 6 = 97^o[/tex]

[tex]\angle 7 = 114^o[/tex]

[tex]\angle 2 = 83[/tex]

[tex]\angle 3 = 66[/tex]

[tex]\angle 5 = 83^o[/tex]

[tex]\angle 8 = 66^o[/tex]

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The equation of the line is;

2(x - 3) - 6y = 10

Placing the line in slope intercept form we get;

6y = 2x - 6 - 10

6y = 2x - 16

Dividing throughout by 6 we get;

y = [tex]\frac{2}{6}[/tex]x - [tex]\frac{16}{6}[/tex]

Simplifying gives;

y = [tex]\frac{1}{3} x +2 \frac{2}{3}[/tex]

So the slope of this line = [tex]\frac{1}{3}[/tex]

Answer:

It will take 125 minutes or 2 hours and 5 minutes.

Step-by-step explanation:

We can use a proportion.

7 pages is to 5 minutes as 175 pages is to x minutes

7 : 5 = 175 : x

7/5 = 175/x

7x = 5 * 175

7x = 875

x = 125

It will take 125 minutes or 2 hours and 5 minutes.

Answer:

$41.48

Step-by-step explanation:

From the information given, you know that the price that the bookstore pays for a book is marked up 35% and that the selling price of a book is $56, so to be able to find the amount that the bookstore paid for a specific book, you can write the following equation:

x+0.35x=56, where x is the price the bookstore paid for the book.

Now you can solve for x:

1.35x=56

x=56/1.35

x=41.48

According to this, the bookstore paid $41.48 for this book.

Answer:

angle xyb will measure 123 degrees.

Step-by-step explanation:

because we know that angle ayz is 57 degrees and angle xyz is 90, we find that angle xya measures 33 degrees by subtracting 57 from 90. then, we can find angle xyb by subtracting 33 from 180, getting 147 degrees. when we add 147, 33, and 57, we get 237 degrees. finally, we subtract 237 from 360 and get 123 degrees, our final angle. hope this helps:)
