You earn $42 for washing 7 cars. How much do you earn for washing one car? How much do you earn for washing 3 cars? How much do you earn for washing 5 cars?
Answer:
1 car = $6 ; 3 car = $18 ; 5car = $30
Step-by-step explanation:
$ 42 = 7 cars
so 1 car = $42÷7 = $6
so 3 cars = 3 × $6 = $18
so 5 cars = 5 × $6 = $30

Let U = {c, d, e, f, g, h, i) and A = {c, e, h, i). Use the roster method to write the set A'.
A' =
(Use a comma to separate answers as needed.)
HELP MEEE
Given:
The universal set is
U = {c, d, e, f, g, h, i}
The other set is
A = {c, e, h, i}
To find:
The set A'
Solution:
We know that,
Complement of a set A = Universal set - set A
A' = U - A
= {c, d, e, f, g, h, i} - {c, e, h, i}
= {d, f, g}
Therefore, the set A' is A' = {d, f, g}.

Answer:
x = 20
Step-by-step explanation:
The picture shows that there is a right angle (this is indicated by the square in between the two straight lines)
every right angle has a total measure of 90 degrees
knowing this we can say: x + 70 = 90 or x = 90 - 70
either way, you would solve this to get x = 20

What is the image of (-9,0) after a reflection over the x-axis?
Answer:
(-9, 0)
Step-by-step explanation:
When a point is reflected over the x-axis, the x-coordinate stays the same but the y-coordinate turns into its opposite. So, the x-coordinate would stay as -9. Because zero is neither negative nor positive, it doesn't have an opposite. So, the y-coordinate would still be 0.

When playing the roulette at a casino, you have exactly 1/35 chance of winning in each round if you play a single number. Your friend has rigged up some fireworks to be set off when you win. When you win, he sets off the fireworks every time. When you don't win, he accidentally sets off the fireworks 10% of the time. If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?
Answer:
0.2275 = 22.75% probability that you actually won that round
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Fireworks going off
Event B: You won
Probability of fireworks going off.
100% of 1/35 = 0.0286(when you win)
10% of 34/35 = 0.9714(you lost). So
[tex]P(A) = 0.0286 + 0.1*0.9714 = 0.12574[/tex]
Probability of you winning and fireworks going off:
100% of 1/35, so [tex]P(A \cap B) = 0.0286[/tex]
If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0286}{0.12574} = 0.2275[/tex]
0.2275 = 22.75% probability that you actually won that round

Answer: 1859.5 mini bears
Step-by-step explanation:
From the information given in the question,
10 mini bars = 12.1 grams
10 regular bars = 23.1 gram
1 super bear = 2250 grams
To eat enough mini bears to match the super bears, the number that it'll take will be:
Since 10 mini bars = 12.1 grams
1 mini bear = 12.1 grams / 10 = 1.21 gram
Since 1 super bear = 2250 grams, the number of mini bears needed to equate this will be:
= 2250/1.21
= 1859.5 mini bears

Give the coordinates of the point obtained from each reflection. (a) Reflect the point (-3, 7) across the y-axis: 00 (b) Reflect the point (-3, 7) across the x-axis: (01)
Answer:
a) Rule for reflection across y - axis:
(x, y) → (-x, y)(-3, 7) → (3, 7)b) Rule for reflection across x - axis:
(x, y) → (x, -y)(-3, 7) → (-3, -7)-x²-2x+7=-17 help lol
A rectangular box without a top is have a volume of 12 cubic feet. Find the dimensions of
the box that will have minimum surface area.
Select all the options that represent different forms of the number 500,368? A. Five hundred, three thousand, and sixty-eight B. Five hundred thousand, three hundred sixty-eight. C. 5,000 + 300 + 60 + 8 D. 5 hundred thousands + 3 hundreds + 6 tens + 8 ones E. 500,000 + 300 + 60 + 8
Answer:
B, D, and E
Step-by-step explanation:
B. Five hundred thousand = 500,000/ three hundred = 300/ sixty-eight = 68.
D. 5 hundred thousands = 500,000/ 3 hundreds = 300/ 6 tens = 60/ 8 ones = 8.
E. 500,000 + 300 + 60 + 8 = 500,368.

Step-by-step explanation:
Need to do this Help please
Answer:
Step-by-step explanation:
Now e have two figures
1 is ABCD and other is APQD ,
Now to find g and f,
Now the are both figure is ,
Area = length * width
Area ABCD = 39 cm^2
AB* BC = 39
(g+7) * ( f) = 39Again,
Area APQD = AP*QD= 16 cm ^2
(g)*(f)=16from here f =16/g putt it in above equation we get ,
(g+7)*16/g = 39
16*g-39*g+96 =0
-23g +96 = 0
g = 96/23
g =3 cm
Now for f putt in one of the above equation ,
f =16/3
f =5.33 cm
Answer:
f = 3cm g = 6cm
Step-by-step explanation: to find f
Subtract the area of APQD from ABCD then divide by 7
f = (39 - 18)/7
f = 21/7
f = 3
To find g, divide the area of APQD by 3
18/3 = 6
We can do this because of the givens: ABCD is a rectangle, PQ is parallel to AD, so BC=AD=PQ
