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

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.
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
A factory makes rods by cutting plastic pipes that are 5 feet long into 8 rods.
How long is each rod?
Feet is the unit of measurement. One feet of measurement is equal to the 12 inches.The length of the each rod made by the 5 feet long pipe is 7.5 inches.
Given-The length of the pipes is 5 feet.
Total number of roads made by the pipes is 8.
We need to convert the length of the feet into the inches.
How many inches are there in one feet?Feet is the unit of measurement. One feet of measurement is equal to the 12 inches.
As it is known that the one feet has the twelve inches. Thus the number of inches in 5 feet is,
[tex]=5\times12[/tex]
[tex]=60[/tex]
Thus the length of the pipe is 60 inches.
Now the total number of roads made by this pipe is 8. Suppose the length of the each rod is [tex]x[/tex] inch. Thus,
[tex]x=\dfrac{60}{8}[/tex]
[tex]x=7.5[/tex]
Thus the length of the each rod made by the 5 feet long pipe is 7.5 inches.

You are given an isosceles trapezoid ABCD with median XY. Complete the following.
AX = 8, CD = __________

Answer:
CD=16
Step-by-step explanation:
If XY is median then CD equals 16
Length of CD = 16 .
What is Isosceles trapezoid?An isosceles trapezoid can be defined as a trapezoid in which non-parallel sides and base angles are of the same measure.
Given,
Isosceles trapezoid ABCD with median XY.
Median cuts the non-parallel lines of trapezoid in two equal parts.
then,
AX = 8
AB = 2 × AX
AB = 2 × 8
AB = 16
ABCD is isosceles trapezoid
So, Unparallel lines are equal,
AB = CD
⇒ CD = 16 unit.
Hence, 16 unit is length of CD.

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
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)The present age of Andy and Mike are in the ratio 5:3. If Andy had been 7 years older and Mike 7 years younger, the age of Andy would have been 3 times the age of Mike. Find their present age
Answer: Andy is 35 and Mike is 21.
Step-by-step explanation:
Andy’s present age: Mike’s present age
= 5:3
Andy’s age in “if”: Mike’s age in “if”
=6:2
1 unit = 7
5 unit = 35 (Andy’s age)
3 unit = 21 (Mike’s age)
