Answer:
1/4
Step-by-step explanation:
1 red marble, 8 green marbles. 9 blue marbles
There are 1+8+9 = 18 marbles
First marble blue
P(blue) = blue / total = 9/18 = 1/2
He replaces the marble so there are still 18 marbles
1 red marble, 8 green marbles. 9 blue marbles
There are 1+8+9 = 18 marbles
Second marble blue
P(blue) = blue / total = 9/18 = 1/2
Multiply the probabilities together
P(blue, replace, blue) = 1/2 * 1/2 = 1/4

Answer:

Step-by-step explanation:
Equations to remember:
Length · Width · Height = Volume
LWH = V
---------------------------------------------------
Length = 5/4
Width = 4/3
Height = 3/5
Your equation will look something like this:
[tex]\frac{5}{4} * \frac{4}{3} * \frac{3}{5} = V[/tex]
or
[tex]\frac{5*4*3}{4*3*5} = V[/tex]
----------------------------------------------------
The simple thing about this problem is that, no matter what order they're in, you're multiplying the same numbers on the top and the bottom. Whatever the top is (5*4*3), the bottom will be (4*3*5). If the top and bottom are equal, that means that you'll have a whole number of 1.
----------------------------------------------------
NOMINATORS
[tex]5 * 4 = 20\\20 * 3 = 60[/tex]
So the top will be 60.
----------------------------------------------------
DENOMINATORS
[tex]4 * 3 = 12\\12 * 5 = 60[/tex]
The bottom will also be 60.
-----------------------------------------------------
[tex]\frac{60}{60} = \frac{1}{1} = 1[/tex]
So your answer will be [tex]1cm^{3}[/tex]!

Darren and his friend save money for vacation Darren start with $120 in savings each week Darren add $40 to savings Darren’s friend Also begins with $120 in savings but saves at a faster rate than Darren create an equation that could represent the amount of money Y in dollars that Darren’s friend sees vacation after X weeks
Define the variables:
y= amt. of $ saved by Darren's friend
x= # of weeks
Darren adds $40 to his savings EVERY WEEK. He also started with $120, so the equation is:
y=40x+120
A bicycle has a listed price of $811.99 before tax. If the sales tax rate is 6.5% , find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
811.99x1.065=864.77
Step-by-step explanation:
Since it is a sales tax, and not something else, we would add a 1 on the front of it, to essentially just "add" back that 811.99, even though it is multiplication. 1.065 times 811.99 is the same as (811.99x.065)+811.99.
Divide.

a movie theater offers a reward program that charges a yearly membership fee and a discounted rate per movie ticket. The total cost for a reward program member to see 5 movies is $40.00 and a total costs for 12 movies is $75.00. Assume the jkrelationshup is l near write the equation of the function in the form y=mx+b when x represents the number of movies and y represents the total cost.
Answer:
— The total cost for a reward program member to see 5 movies is $40 and the total cost for 12 movies is $75. Assume the relationship
Step-by-step explanation:
The equation of the function is y = 5x+5, where x represents the number of movies and y represents the total cost.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, The total cost for a reward program member to see 5 movies is $40.00 and a total costs for 12 movies is $75.00.
The coordinates of the equation can be (5, 40) and (12, 75)
The equation of a line passing from two points is given by,
y-y₁ = (y₂-y₁)/(x₂-x₁)(x-x₁)
y-40 = (75-40)/(12-5)(x-5)
y-40 = 35/7(x-5)
y = 5x-25+40
y = 5x+15
Hence, the required equation is y = 5x+15

Gabe goes to the mall. If b is the number of items he bought, the expression 15.41b+28 gives the amount he spent in dollars at one store. Then he spent 27 dollars at another store. Find the expression which represents the amount Gabe spent at the mall. Then estimate how much Gabe spent if he bought 2 items.
Answer:
Gabe spent about $86 if he bought 2 items.
Step-by-step explanation:
First store: 15.41b+28? Second store: $27b = number of items he bought15.41b+28+27 = $?
15.41b+55 = $?

A meteorologist recorded the rainfall in Oakdale in two consecutive months. In the first month, there were 1 6/12 inches of rain. In the second month, there were 1 inch of rain. What was the total amount of rainfall during the two months?
Answer:
There were 2 1/2 inches of rain in 2 months.
Step-by-step explanation:
1. Reduce 1 6/12 to 1 1/2.
2. Add 1 1/2 and 1 (if it is easier for you to add decimals you can reduce the 1 1/2 to 1.5 by dividing 1 by 2. In that case you would get 2.5 as your final answer). The answer is 2 1/2.

Part A
Answers:To find the area of the unshaded region, subtract the area of the shaded region from the sum of the areas of the rectangle and semicircle
----------------
Explanation:
When it comes to area problems, think of a grid of squares. Let's say we had a 10 by 10 grid of tiny squares (10*10 = 100 total). Now let's say 8 of them are shaded in. There are 100 - 8 = 92 unshaded squares to represent the total area of the unshaded region.
That's effectively what's going on with this problem as well. Sure things get a bit tricky with that curved portion on top, but we can still get an approximation if we use smaller and smaller grid sizes. I recommend using graph paper or graphing software that provides a grid.
========================================================
Part B
Answer: 811----------------
Explanation:
For now, I'm going to ignore the shaded region. I'll come back to it later.
The rectangle is 15 ft by 50 ft. It has an area of length*width = 15*50 = 750 sq ft.
The semicircle up top has an area of [tex]0.5*\pi r^2 = 0.5*\pi*(7.5)^2 \approx 88.3573[/tex] sq ft approximately. The 7.5 is from dividing the diameter in half to get the radius. As the instructions stated, I used the calculator's version of pi.
The rectangle and semicircle have their areas add to
750+88.3573 = 838.3573
Now we can finally address the shaded region. It is a 3 ft by 9 ft rectangle because "the length is 3 times the width" and the width is 3 ft. This shaded rectangle has area 3*9 = 27 sq ft.
The unshaded region is:
unshaded = total - shaded = 838.3573 - 27 = 811.3573
This rounds to the final answer of 811

To rent a certain meeting room, a college charges a reservation fee of $31 and an additional fee of $5.70 per hour. The history club wants to spend less than $82.30 on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
Use for the number of hours the meeting room is rented, and solve your inequality for .
Answer:
x [tex]\leq[/tex] 9
Step-by-step explanation:
31 + 5.70x [tex]\leq[/tex] 82.30
subtract 82.30 by 31

Laura started a race at 6:39 PM and finished it at 7:15 PM.
How long did it take her? Give your answer in minutes.
Answer:
36 mins
Step-by-step explanation:
7:15 - 6:39 = 36 mins
She finished the race in 36 mins.
Have a good day/night
Answer:
36 minutes
Step-by-step explanation:
You subtract the time she started from the time she finished.
So, it would be 7:15 - 6:39.
It would be easier to find the number that, when added to 6:39, results to 7:00.
To do so, you subtract 39 from 60.
60 - 39 = 21 minutes
Now, add 21 to 15.
21 + 15 = 36 minutes
Therefore, it took her 36 minutes to complete the race.
