Answer:
R=110 degrees
B=110 degrees
Step-by-step explanation:
R and B are the same angle, we minused the mesure of G and since angle O is same as the other angle we multiplied 60 by two and then added 20 which gave us 140
360-140=R+B
220=R=B
110=R
110=B
Answer:
m<R = 120 degrees, m<B = 100 degrees
Step-by-step explanation:
1. i found the blue line and the angle of any line is 180 degrees
2. since angle O is 60 you have to subtract it from 180 -60 = 120 = m<R.
3. this one is more complicated you have to subtract angle O and angle G which is 20 degrees so you add 20 + 60 = 80 and then you take the sum and subtract it from 180: 180 - 80 = 100
1. A box of pencils is 5 1/4 inches wide. Seven pencils, laid side by side, take up 2 5/8 inches of the width.
How many inches of the width of the box is not taken up by pencils. Show your reasoning.
2. All the pencils have the same width. How wide is each pencil? Show your reasoning.

Every Sunday morning, Opal, Lisa, Talia, and Cora meet for breakfast at the Bagel Shop.
They share the bill equally and each pay $2 toward the tip. The expression 1/4x +2 represents
the amount each friend pays, where z is the amount of the bill before the tip.
The term 1/4x represent the amount each friend pays bill before the tip.
And, The term 2 represent the amount each friend pays towards the tip.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 1/4x + $2
Which represents the amount each friend pays.
Where, x is the amount of the bill before the tip.
Now,
Since, The expression is,
⇒ 1/4x + $2
Where, x is the amount of the bill before the tip.
Hence, We get;
The term 1/4x represent the amount each friend pays bill before the tip.
And, The term 2 represent the amount each friend pays towards the tip.

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover
1 3/5 doors. How many liters of paint are needed for 1 door?
I need an explanation with the answer and I need it today :)
Answer:
I think it's 1 1/4 liters of paint for one door
Step-by-step explanation:
First you have to turn it to an improper fraction
1.) 1 3/5 = 8/5
Then you have to proportion the fraction with the 2 liters (L=liters)
2.) 2/(8/5)
= 10/8 L
3.) Next you convert the fraction to a mixed number
10/8 L --> 8/8 + 2/8 = 1 1/4 L
8. Explain why 30+1 = 6 is the same as 30 -/-/--/-X-X = 0. What is
the value of x in this example?
Answer:
5
Step-by-step explanation:
5 because of two ways one you could do 6*what is 30. Or you could do repeated addition 30=5+5+5+5+5+5. But when you do 30=5-5-5-5-5-5. You are doing repeated subtraction which is equivalent to 30-5*6= 0.

Drag the answers to match the inequality and the situation it represents.
Answer:
b < 11 = The baby weighs at least 11 pounds.
b > 11 = The box contains more than 11 books.
b < 12 = There are fewer than 12 beetles in a jar.
b > 12 = The building is taller than 12 feet.
Step-by-step explanation:
The baby weighs at least 11 pounds is b < 11 because the baby weighs more than 11 pounds.
The box contains more than 11 books is b > 11 because there are more books in the box than 11.
There are fewer than 12 beetles in a jar is b < 12 because there are less than 12 beetles in a jar.
The building is taller than 12 feet is b > 12 because 12 feet is less than how tall the building is.

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
(A) The scale factor of the dilation that transforms Triangle PQR to Triangle P'Q'R' is 1/4
(B) Coordinates of Δ P"Q"R"
P" (-1,0)
Q"(0,-1)
R"(2,-1)
(C) Triangles PQR and P"Q"R" are not congruent.
Given
ΔPQR is transformed into ΔP'Q'R'
Coordinates of P, Q, R are
P (4,0),
Q(0,-4)
R(-8,-4)
Coordinates of P'Q'R' are
P'(1,0)
Q'(0,-1)
R'(-2,-1)
(A) By Distance formula we can find the distance between P Q and P'Q'
Distance formula =
Where D = Distance between two points
from distance formula we can write that
PQ =
Similarly
P'Q'=
PQ /P'Q' = 4
hence the scale factor of dilation is 1/4 (Compression)
(B )The Coordinates of Reflection about y axis can be written for a point
So the Coordinated of Δ P"Q"R" can be written as
P" (-1,0)
Q"(0,-1)
R"(2,-1)
(C) ΔPQR and ΔP"Q"R" are similar triangles but they are not congruent because their sides are not equal in size.

Square Area
8-3 to get the right side of the square which equals 5. So the square is 5*6=30
Triangle Area
To get the area of a triangle the formula is a=b*h*1/2, so base is 3 and height is 3, we would do 3*3*1/2 which equals 4.5
but you have 2 triangles so multiply 4.5*2 and that's 9.
Conclusion
So, 30+9=39
