1. what is the measure of angle B? (image included below)
2. What is the value of x? (image included below)
Answer:
1. 47 2. 49
Step-by-step explanation:
1st is complementary and second is supplementary
Answer:
Step-by-step explanation:
b+43˚=90˚
subtract 43˚ from both sides of the equation
b=47˚
3x+33˚=180˚ (because it's a straight angle)
subtract 33˚ from both sides
3x=147˚
divide both sides by 3
x= 49˚

THE PROBABILITY THAT A BOY IS LEFT-HANDED IS 0.1
ESTIMATE THE NUMBER OF LEFT-HANDED STUDENTS IN THE SCHOOL
Answer:
89
Step-by-step explanation:
I just multiplied 320 by 0.2 and then 250 by 0.1 and then added them together. I hope it helps and I'm not sure what method you would use for this but that's mine.
Solve for x. Assume that line which appear to be diameters are actual diameters.
Answer:
x = 8
Step-by-step explanation:
The angle above the 6x-8 = 180 -140 = 40
The angle on the opposite side is 40 degrees as well because they are vertical angles
6x-8 = 40 degrees
Add 8 to each side
6x= 48
Divide by 6
6x/6 = 48/6
x = 8

Direct Variation: If y = 9, when x = -3, find x when y = -27. a.9 b.27 c.-27 d,-9
Answer:
a. 9
Step-by-step explanation:
[tex]k = \frac{9}{-3} = -3\\y = -3x\\-27 = -3x\\\frac{-27}{-3} = \frac{-3x}{-3} \\9 = x[/tex]
Answer:
a. 9
Step-by-step explanation:
because the orginal number was 9 and the newer one is -27 we can determine that y was multiplied by -3 so you would apply the same rule to -3 or x and you would get a product of 9 because two negatives equals a postive

Which of the following best describes the graph shown below?
Answer:
B. This is a graph of a one to one function
Answer:B
Step-by-step explanation:
Which describes unit rates? Check all that apply.
-Nadia pays $30 for 2 baseball tickets.
-A certain type of sailboat travels at 7 nautical miles per hour.
-The cost of 3 hot chocolates is $2.
-A summer camp provides 3 meals for each camper.
Answer 2,4 are all described as unit rates a unit rate is anything that has per or each in it so a certain type of boat travels at 7 hours PER mile so we know question 2 is correct and 3 is a unit rate because it has each in it A summer camp provides 3 meals for EACH camper. That’s why the answer is 2 and 4

Why do you think you can prove congruency with SSS but not with AAA Property. Explain your answer with figures.
In AAA (Angle-Angle-Angle), triangles do not have the same size and only have 3 pairs of congruent angles.
In SSS (Side-Side-Side), if the three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent.
Please solve each algebraically : a) 5w= 30 b) 3x - 5 = 16 c) 10 - t = 17 d) n/5 = 18 e 4w -12 =2w + 3 THANK YOU!
Answer:
w=6, x=7, t=7, n=90, w=15/2
Step-by-step explanation:
a) 5w = 30
30/5 = 6
w=6
b) 3x-5=16
Add 5 to each side.
3x+5=16+5
3x=21
21/3=7
x=7
c) 10-t=17
10-t=17
17-10-7
-t=-7
Negative and a negative is a positive.
t=7
d) n/5 = 18
n=18 * 5
n=90
e.) 4w-12=2w+3
4w=2w+3+12
4w=2w+15
4w−2w=15
2w=15
w= 15/2
Find the minimum value of C=x+3y
Answer:
c
Step-by-step explanation:
2x + 3y > 6 (1)
3x – 2y = 9 (2)
x + 5y = 20 (3)
From (1) and (2), we have:
(2x + 3y) - (3x - 2y) > 6 - 9
5y - x > -3 (4)
From (3) and (4), we have:
(x + 5y) - (5y - x) > 20 - (-3)
2x > 23
x > 12,5 (5)
From (3) and (5), we have:
x + 5y = 20 ⇔ 12,5 + 5y > 20
5y > 7,5
y > 1,5
So: C = 4x + 3y > 12,5 × 4 + 1,5 × 3 = 50 + 4,5 = 54,5
Conclusion: C > 54,5

Wes mixed different juices to make fruit punch. He filled one-half of the punch bowl with orange juice. Then he filled half of the remaining space with grape juice. Finally, he filled the rest of the punch bowl with 300\text{ mL}300 mL300, start text, space, m, L, end text of cherry juice.
Answer:
1.2Litres
Question:
Wes mixed different juices to make fruit punch. He filled one-half of the punch bowl with orange juice. Then he filled half of the remaining space with grape juice. Finally, he filled the rest of the punch bowl with 300 mL300\text{ mL}300 mL300, space, m, L of cherry juice. How many liters of fruit punch did Wes make?
Step-by-step explanation:
Let the total punch bowl be = P
Portion of Orange juice = ½ of total punch bowl
= ½ × P = P/2
Portion of grape = ½ of the remaining space
Remaining space = P - P/2 = P/2
Portion of grape = ½ × P/2 = P/4
The rest of the punch bowl is for cherry = 300mL
P/2 - P/4 = 300
(2P - P)/4 = 300
P/4 = 300
P = 300×4
P = 1200mL
1mL = 10^(-3)L
P = 1.2 ×10³ × 10^(-3)L
P = 1.2L
Wes made 1.2liters of fruit punch.

In a carnival game, there is a machine that will shuffle a deck of 50 cards numbered from 1 to 50 and then spit one card out. If the number on the card is odd, you win $15. If the number on the card is even, you win nothing. If you play the game, what is the expected payoff?
$___
Answer:
$7.50
Step-by-step explanation:
Since there is a 50% chance that the card is odd, the expected payoffs would be $15 * 50%=0.5*15=7.5. Hope this helps!

Answer: The acute angle between diagonals is 50
Step-by-step explanation:
Red angle = 50 because An exterior angle of a triangle is equal to the sum of the opposite interior angles (pink angles).
Alternatively:
Green angle is 130 by sum of interior angles of a triangle.
Red angle is 50 by Adjacent angles
