There are 12 boys and 13 girls in a class. If the teacher randomly chooses a student's name out of a hat, what is the probability it will be a girl?
◯ 48%
◯ 50%
◯ 52%
◯ 92%
The probability of selecting a girl is 52%
How to determine the probability?The given parameters are:
Boy = 12
Girl =13
The probability of selecting a girl is:
P(Girl) = Girl/Total
This gives
P(Girl) = 13/(12 + 13)
Evaluate
P(Girl) = 52%
Hence, the probability it will be a girl is 52%

A store purchased jeans for $15 a pair. The store increased the price of the jeans by 65%. One month later, the jeans were on sale for 15 - off the store price. How much would a customer pay for the jeans on sale? Please help
Answer:
$21.04
Step-by-step explanation:
Steps to take to derive the answer
Determine the price after the price increase of 65%Determine the price after the 15% offPrice after increase increase (100% + increase in price) x purchase price of the jeans
(100% + 65%) x 15
165% x 15
1.65 x $15 = $24.75
Price after the decrease in price = (100% - percentage decrease in price) x price after the 65% increase in price
(100% - 15%) x $24.75
85% x $24.75
0.85 x $24.75 = $21.04

`what is the sooulition to x + 8 = 25
Answer:
17
Step-by-step explanation:
Well you have to get x by itself so....
subtract 8 from both sides
25 -8 = 17 there is your answer
Hey there!
x + 8 = 25
SUBTRACT 8 to BOTH SIDES
x + 8 - 8 = 25 - 8
SIMPLIFY IT!
x = 25 - 8
x = 17
Therefore, the answer should be: x = 17

Answer: The answer is D (Mr. Johnson will earn $140 for 12 hours of work
Step-by-step explanation:
So with process of elimination we can safely say that for every hour Mr. Johnson will earn 12$.
So it is true that *A* e(amount earned)= 12h($12 made per hour)
And if *B* Mr. Johnson makes $12 per hour then in 4.5 hours he will make $54
We also know for a fact *C* Mr.Johnson earns $12 per hour
but in 12 hours Mr. Johnson will make $144 not $140 so *D* is incorrect

Answer:
x = 8, y = 12
Step-by-step explanation:
Since the triangles are congruent, we know that the parallel sides are equal to each other.
So,
4x - 7 = 3x + 1
4x - 3x = 1 + 7
x = 8
x + y = 20
8 + y =20
y = 20 - 8
y = 12

Step-by-step explanation:
Vanessa throws a tennis ball in the air. The function h(t) = -15t2 + 45t + 10 represents the distance in feet, that the ball is from the ground at any time in seconds, t. What is the maximum height of the ball?
Answer:
43.75feet
Step-by-step explanation:
Given the height of the tennis ball expressed as;
h(t) = -15t^2 + 45t + 10
At maximum height, the velocity of the ball is zero
v = dh/dt
dh/dt = -30t + 45
Since dh/dt = 0, hence;
0 = -30t + 45
30t = 45
t = 45/30
t = 3/2
t = 1.5secs
Substitute t = 1.5 into the expression given
h(1.5) = -15(1.5)^2 + 45(1.5) + 10
h(1.5) = -15(2.25)+67.5+10
h(1.5) = -33.75+77.5
h(1.5) = 43.75feet
Hence the maximum height of the ball is 43.75feet
