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)

Use the Distributive Property to simplify. s 5 a solution to 2t - 1 = 11?
Answer:
5 is NOT a solution to the equation.
t = 6
Step-by-step explanation:
Step 1: Write out equation
2t - 1 = 11
Step 2: Add 1 to both sides
2t = 12
Step 3: Divide both sides by 2
t = 6
The slope of the line represented by the equation 2(x - 3) - 6y = 10 is
equal to what?
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]
Jose can read 7 pages of his book in 5minutes . At this rate how long will it take him to read the entire 175 page book.
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.

The measure of two vertical angles are given by the expressions (x+3) and (2x-7). Find the value of x.
Answer:
61.3
Step-by-step explanation:
two vertical angles add up to 180°
so (x+3)+(2x+7)=180°
open brackets & collect like terms
x+3+2x-7=180°
3x+-4=180°
3x=184°
x=61.3 after dividing by 3 on both sides

1. What is a proportion? Show example.
2. How do you solve propositions?
3. What is the “easy” method to solving proportions?
Answer:
1.a part, share, or number considered in comparative relation to a whole.
1/3 = 2/6
2.If a proposition is true, then we say it has a truth value of "true"; if a proposition is false, its truth value is "false". For example, "Grass is green", and "2 + 5 = 5" are propositions. The first proposition has the truth value of "true" and the second "false".

What is -8-__=-5
And how do i do it step by step?
Answer:
-3
Step-by-step explanation:
-5 is greater than -8, so in order for a subtraction problem to give a higher number is if it is negative, because a negative negative is a positive.
-8--3=-5
This is another way of saying
-8+3=-5
The measure of AngleRST can be represented by the expression (6x + 12)°.
Three lines extend from point S. The space between lines S R and S U is 78 degrees. The space between lines S U and S T is 3 x minus 12.
What is mAngleRST in degrees?
78°
84°
120°
156°
Answer:
The Answer is: C.120
Trust me it is right.Good Luck:)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°

Are the equations – 2x = 10 and -5x = 25 equivalent?
Answer: [tex]Yes[/tex]
Q: How are they the same answer?
A: You divide both of them by the number with x.
Divide both sides by -2
[tex]-2x/-2=10/-2\\x=-5[/tex]
Divide both sides by -5
[tex]-5x/-5=25/-5\\x=-5[/tex]
That's how both of them are equivalent to each other.

If m<9=97 and m<12=114, find each measure.
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]
