Step-by-step explanation:
Using a standard deck of playing cards, what is the probability of drawing a four, replacing the card, and then drawing a club?
A. 1/26
B. 1/51
C. 17/52
D. 1/52
Answer:
D. 1/52
Step-by-step explanation:
There are four 4s in a deck of 52 cards, so there is a 4/52 chance of drawing a four on the first try.
Once you replace the card in the deck, the simulation starts over, meaning the events are independent and you are once again drawing from 52 possible cards.
Now, when you draw the club, the chance of this is 13/52 because there are 13 clubs in a deck.
Because events are independent, multiply the probabilities to determine the chance that both events occur.
[tex]\frac{4}{52} * \frac{13}{52}[/tex] = 1/52
Solve 1=4|x-2|+2
Help please
Answer:
No solution
Step-by-step explanation:
1=4|x-2|+2
-4|x-2| + 1 = 2
-4|x-2| = 1
False for every value of x
Since absolute value gives only a positive value, the -4 would always make that number negative which doesn't work

Identify if first number is divisible by the second number, and if so, the reason why.
Is 94,032 divisibly by 9?
A. No
B. Yes, because the sum of the digits is 9 + 4 + 0 + 3 + 2 = 18, which is divisible by 9.
C. Yes, because the value of the first digit is 9, which is divisible by 9.
Answer:
yes b

Moutain climber A is at altiude of 250 feet and is descending at a rate of 30 feet per hour. Moutain climber B is at an altitude of 400 feet and is descending at a rate of 50 feet per hour. In how many hours will the altitude of moutain climber B be lower than the altitude of moutain climber A?
Answer:
the altitude of mountain climber b will be lower than the altitude of mountain climber A with number of hours greater than 7.5hrs.
Step-by-step explanation:
This talks about equalities in math,
We are told about Moutain climber A is at altiude of 250 feet and is descending at a rate of 30 feet per hour, this can be interpreted as
250 - 30h
Moutain climber B is at an altitude of 400 feet and is descending at a rate of 50 feet per hour, this can be interpreted as
400 - 50h
We were now asked how many hours the altitude of mountain climber b be lower than the altitude of mountain climber A, we can interpret this as
(400 - 50h) < (250 - 30h )
We can collect the like terms here
-50h + 30h < 250 - 400
-20h < - 150
The negatives sign can cancelled out, we have
Note that multiplying or dividing by a negative THE INEQUALITY SIGN MUST BE FLIPPED
20h > 150
h > 150/20
h > 7.5
Therefore, the altitude of mountain climber b will be lower than the altitude of mountain climber A with number of hours greater than 7.5hrs.
A school raises money by selling 0.5 bags of nuts.
They buy:
-30 pounds of cashews
-15 pounds of almonds
-5 pounds of peanuts
How many 0.5 pound bags can they make?
Answer:
100 bags
Step-by-step explanation:
Answer:
100 bags
Step-by-step explanation:
You're going to want to multiply each amount of pounds the bags are by two. So 30 × 2 is 60. 15 × 2 = 30. 5 × 2 = 10.
60 + 30 = 90
90 + 10 = 100
A healthy human heart beats about 1,533,000 times a year. A sparrow's heart beats about 2,417,760,000 times in a year. About how many times faster does the sparrow's heart beat compared to the human heart? Show your work.
Answer: 1577.14
Step-by-step explanation:
From the question, we are informed that a healthy human heart beats about 1,533,000 times a year and that a sparrow's heart beats about 2,417,760,000 times in a year.
To calculate how many times faster the sparrow's heart beat compared to the human heart, we divide the sparrow's heartbeat in a year by the humans heartbeat in a year. This will be:
= 2,417,760,000 / 1,533,000
= 1577.14 times
what is the solution of −2 < x/4
Answer:
Inequality Form: x > −8
Interval Notation: (−8, ∞)
Step-by-step explanation:
−2 < x/4
Rewrite so x is on the left side of the i nequality.
x/4 > −2
Multiply both sides of the equation by 4.
x > −2 ⋅ 4
Multiply −2 by 4.
x > −8
The result can be shown in multiple forms.
Inequality Form:
x > −8
Interval Notation:
(−8, ∞)

A T-shirt printing machine takes 80 minutes to print 1120 shirts. Consider the number of shirts printed per minute. Find the constant of proportionality in this situation. b. Write an equation to represent the relationship. How many shirts are printed in 30 minutes?
Answer:
Every minute there are 14 shirts made so there would be 420 shirts made in 30 minutes. Y=14x
Step-by-step explanation:
Divide 1120 by 80 to get 14 then you multiply 14 by 30 to get 420
Then to get an equation you write the number of shirts made per minute and then plug in how many minutes you want.

The graph below shows the cost of pens based on the number of pens in a pack. What would be the cost of one pen?
$0.57
$1.75
$5.50
$6.50
Answer:
$1.75
Step-by-step explanation:
Honestly, you don't really have to pay attention to the other numbers or ratios on the graph until you think you found your answer. Pay attention to whichever ratio you choose and follow these steps:
1. Identify which number is the cost and which is the amount of pens bought
2. Set it up as a division problem by using the cost and the dividend and the amount of pens as the divisor
3. After you have your answer, plot your ratio of 1:(your product) and if the line that was graphed is straight, you are correct.
PS. I used the ratio (2:3.5) to solve this problem
four glasses of milk and 2 snack bars have a total of 68 carbohydrates (carbs), and 2 glasses of milk and 3 snack bars have a total of 62 carbs. Determine how many carbs are in one glass of milk and in one snack bar.
Answer: One glass of milk = 10 carbs
Answer: One snack bar = 14 carbs
Step-by-step explanation:
Four glasses of milk and Two snack bars.
4 x 10 = 40
2 x 14 = 28
40 + 28 = 68
Two glasses of milk and Three snack bars.
2 x 10 = 20
3 x 14 = 42
20 + 42 = 62
what is the slope of the line
Answer:
-3
Step-by-step explanation:
Slope is rise over run or the change in y over change in x. So to find the slope count the difference from one point to the next, for example (0,4) and (1,1). In this case, the y-value decreases by 3, so -3, and the x-value increases by 1, so +1. Which would be -3/1 or just -3. One way to visually check is to remember that slopes less than -1 or greater than 1 make the line steeper and negative slopes make the graph decrease from left to right.

A circle has a diameter of 8 centimeters, as shown below.
8 cm
What is the area, in square centimeters, of the circle?
Answer:
12.6cm²
Step-by-step explanation:
Diameter of circle = 8cm
Unknown:
Area of the circle = ?
Solution:
The area of the circle is given by the expression below;
Area = π r²
r is the radius of the circle
Since diameter is 8cm, radius = 4cm
Insert the parameters;
Area of circle = π x 4cm = 12.6cm²
Answer:50.3

Tannis's first machine could throw a car 272727 meters. She studied her first machine and built a better one. Her second machine could throw a car 777 times as far.
How far does the second machine throw a car?
Answer:
The rate of change of the distance between the cars at that instant is 5.46 meters per second
Step-by-step explanation:
Speed of first car = 7 m/s
Speed of second car = 3 m/s
At instant, distance of first car from intersection = 5 meters
distance of second car from intersection = 12 meters
Therefore, we have
Distance between both cars at intant = √(12² + 5²) = 13 m
Rate of change of distance is given by;
2ddd/dt = d(x² + y²)/dt = 2xdx/dt + 2ydy/dt
= 26dd/dt = 2×5×7 + 2×12×3 = 142
dd/dt = 142/26 = 5.46 m/s.
That is the rate of change of the distance between the cars at that instant = 5.46 meters per second.
