Answer:
77
Step-by-step explanation:
The sum of the measures of the two given arcs is 180°, the measure of semicircle ADC. Using this fact, we can find x and the measure of DC.
AD +DC = 180
(19x -49) +(5x +37) = 180
24x = 192 . . . . . . . . . . . add 12, simplify
x = 8 . . . . . . . . . . divide by 24
Then the measure of DC is ...
DC = 5x +37 = 5(8) +37 = 40 +37
DC = 77

The drama club members estimate that they need 800 bags of popcorn to serve during the intermission of their play. Popcorn comes in cases of 25 bags. How many cases of popcorn will they need?
Answers
Answer:
32cases
Step-by-step explanation:
Total number of bahs of popcorns needed = 800bags
Number of bags per case = 25bags
Required
The total cases of popcorn they will need.
Total cases of popcorn needed = Total number of bags/number of bags per case
substitute the given values
Total cases of popcorn needed = 800/25
Total cases of popcorn needed = 32 cases
Hence 32cases of popcorns will be needed

Solve the system by elimination.
-6x + y = 0
9x - 8y = 4
Answers
Answer:
(4, 4 )
Step-by-step explanation:
Given the 2 equations
- 6x + 6y = 0 → (1)
9x - 8y = 4 → (2)
Multiplying (1) by 3 and (2) by 2 and adding will eliminate the x- term, that is
- 18x + 18y = 0 → (3)
18x - 16y = 8 → (4)
Add (3) and (4) term by term to eliminate x, then
2y = 8 ( divide both sides by 2 )
y = 4
substitute y = 4 into either of the 2 equations and solve for x
Substituting into (2)
9x - 8(4) = 4
9x - 32 = 4 ( add 32 to both sides )
9x = 36 ( divide both sides by 9 )
x = 4
Solution is (4, 4 )

Answers
Answer:
x=-3
Step-by-step explanation:
Vertical angles are always equal. We need to set the equations inside of the parenthesis equal.
3x+26=x+20
subtract x from both sides
2x+26=20
subtract 26 from both sides
2x=-6
divide both sides by 2
x=-3

Part A:
0.1111111111111 = 1/9
Part B:
3
Step-by-step explanation:
Part A:
When I put 0.111111111 into my calculator I get a conversion of 1/9.
Part B:
The fraction 1/9 means that for every 9 kids he surveyed, 1 of them replied "yes."
So covert 1/9 into x/27
27/9 = 3 which means 9 goes into 27, 3 times.
Multiply 1 by 3.
1 x 3 = 3
Put into fraction form
3/27
This means 3 students out of 27 answered "yes."

14, 1352, 36.8, 50.8, 50.8
Step-by-step explanation:
We get 14 by looking at the other measurement of the triangle that was given to us. We add the two values of 196 and 1156 to find the value of c^2.To find c, we would have to take the square root of c^2 (aka 1352), which will give us 36.8. The next blank is simple, you would just add 36.8 + 14 to get 50.8 just like it is shown in the problemWrite the same answer into the last blank.Hope this helped!
What is (x+2)(x-4)(x+6)
Answers
Answer:
x³ + 4x² - 20x - 40
Step-by-step explanation:
Break it up into parts
(x+2)(x-4)(x+6)
( (x+2)(X-4) )(x+6)
Multiply (x+2)(x-4)
Breaking up the brackets, you get:
x(x-4)+2(x-4)
=x² - 4x + 2x -8
=x² - 2x - 8
Now multiply this by (x+6)
(x+6)(x² - 2x - 8)
= x³ - 2x² -8x + 6x²- 12x - 40
= x³ + 4x² - 20x - 40
