If the sum of measures of angle a and b is 280 degrees, what is the measure of angle C?
A. 80 degrees
B. 160 degrees
C. 140 degrees
D. 40 degrees
Answers
Answer:
40 degrees
Step-by-step explanation:
because angle b and angle a are vertical angles they are congruent and if they add up to 280 you just have to divide that by 2 to get the value of one of the angles
280/2=140
because angle c and angle b are supplementary they are going to add up to equal 180
180-140=40 so c=40
Answer:
40

My recipe calls for 3/4 cup sugar, 3/5 cup flour. If I use 3/8 cup of flour how much sugar do I need?
Answers
Answer:
15/32 cups
Step-by-step explanation:
Given data
We are given data 3/4 cups of sugar required 3/5 cups of flour
What amount sugar requires 3/8 cups of flour is the question
Solution
3/4 cups of flour needs 3/5 cups of sugar
Hence x cups of flours need 3/8 cups of sugar
cross multiply
3x/5= 3/4*3/8
3x/5= 9/32
3x= 9*5/32
3x= 45/32
x= 15/32
Hence the amount of flour is 15/32 cups

The point (2, 18) is an ordered pair in a proportional relationship. What equations represents this relationship?
y = 1/9x
y = 18x
y = 9x
y = 2x
Answers
Answer:
y = 9x
Step-by-step explanation:
If you plug in the point into each equation, you get:
y = 1/9x
18 = 1/9 * 2
18 = 2/9
not true
y = 18x
18 = 18 * 2
18 = 36
not true
y = 9x
18 = 9 * 2
18 = 18
true, so this is the answer
y = 2x
18 = 2 * 2
18 = 4
not true
