William bought 16 gallons of gas for $37.76. Regina spent $14.64 on 6 gallons of gas. Who got a better deal per gallon?

Answer:
Step-by-step explanation:
sin24° = 8/x multiply both sides by x
x*sin24° = 8x/x divide both sides by sin24°
x= 8/sin 24°
x ≈ 19. 69
What are sets and how can they be represented ?
There are 130 people in a sport centre.
61 people use the gym.
68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
Given that a randomly selected person uses the gym and the track, what is the probability they do not use the swimming pool?
Answer:
13 / 19
Step-by-step explanation:
Given that :
U = 130
Let :
s = swimming pool
t = track
g = gym
n(g) = 61 ; n(s) = 68 ; n(t) = 60
n(g n s) = 25 ; n(t n s) = 30 ; n(g n t) = 19
n(g n s n t) = 6
n(g n t) only = n(g n t) - n(g n s n t) = 19 - 6 = 13
Hence, probability that a randomly scted person uses the gym and track and does not use the swimming pool = n(g n t) only ÷ n(g n t)
= 13 / 19
= 13 / 19

HELP. car takes 10 hour and 30 minutes from A to B point. how many hours will it take for car if it's speed increases 1.2 times?
(distance doesn't change)
9514 1404 393
Answer:
8 3/4 hours
Step-by-step explanation:
Time is inversely proportional to speed for the same distance. The time for 1.2 times the speed will be 1/1.2 times the given time:
(10.5 h)/1.2 = 8.75 h
It will take 8.75 hours at the increased speed.

Find x such that f(x) = 10 given f(x) = 4x+2
Answer:
x=2
Step-by-step explanation:
So you make the equation equal. f(x)=10 so you would put it as 10=4x+2, than you subtract two from both sides making it 8=4x and than divide both sides by 4 making it 2=x.
Answer:
[tex]\boxed {\boxed {\sf x=2}}[/tex]
Step-by-step explanation:
We know that:
[tex]f(x)=4x+2 \\f(x)= 10[/tex]
Both 4x+2 and 10 are equal to f(x). We can use substitution and set 4x+2 and 10 equal to each other.
[tex]4x+2=10[/tex]
Now, solve for x. Perform the inverse operations to isolate x on one side of the equation.
2 is being added to 4x. The inverse of addition is subtraction. Subtract 2 from both sides of the equation.
[tex]4x+2-2=10-2[/tex]
[tex]4x=10-2 \\[/tex]
[tex]4x=8[/tex]
x is being multiplied by 4. The inverse of multiplication is division. Divide both sides of the equation by 4.
[tex]\frac{4x}{4} =\frac{8}{4}[/tex]
[tex]x=\frac{8}{4}[/tex]
[tex]x=2[/tex]
For the function f(x)= 4x+2, when f(x)=20, x=2

Answer:
Step-by-step explanation:
7x + 3 = 10x - 5.4
Bringing like terms on one side
3 + 5.4 = 10x - 7x
8.4 = 3x
8.4/3 = x
2.8 = x

Mildred has a bag of coins. The bag contains 10 dimes, 5 nickels, and 1 penny. She will randomly select 2 coins from the bag one at a time without replacement. What is the probability that Mildred will select a dime first and then a penny?
Answer:
Total possibilities = 16
Probability of a dime of the first draw is 10/16 = 5/8
Probability of a penny on the second draw = 1/15
Probability of both = 5/8 * 1/15 = 1/24
Damon drank 2 3 liter of water Monday before going jogging. He drank 3 7 liter of water after his jog. How much water did Damon drink altogether? Write your answer as a mixed number. Solve this problem on paper. Then, check your answer on Zearn. Damon drank liters of water altogether.
Answer:
1 2/21 liters
Step-by-step explanation:
Damon drank 2/3 liter of water Monday before going jogging. He drank 3/7 liter of water after his jog. How much water did Damon drink altogether?
Volume of water Damon drank before jogging = 2/3 liters
Volume of water Damon drank after jogging = 3/7 liters
Total volume of water Damon drank altogether = 2/3 liters + 3/7 liters
= 2/3 + 3/7
= 14+9/21
= 23/21
= 1 2/21
Total volume of water Damon drank altogether = 1 2/21 liters

Please help me!! I’m so confused
Answer:
X = 24
Step-by-step explanation:
Just apply H² = B² + P²
(26)² = (10)² + P²
676 = 100 = P²
676 - 100 = P²
P² = 576
P = √576
P = 24
P = X
