Step-by-step explanation:

The formula for a triangle is base x height x 1/2

The triangles on the top and bottom have a base and height of 6 and 12 so: 6x12x1/2= 36 There are 2 of them so: 36 + 36 = 72

The triangles on the sides have a base and height of 8 and 14 so: 8x14x1/2=56 There are also 2 of them so: 56 + 56 = 112

The formula for the area of a rectangle is length x width

The length and width of the rectangle is 6 and 8 so: 6 x 8 = 48

Now add up all of the areas: 72 + 112 + 48 = 232

Kaitlyn has a bag with an equal number of red, yellow, and blue marbles. She makes a tree diagram to show the sample space if she randomly selects two marbles out of the bag.
What is the probability that both marbles selected are different colors?
[diagram in the picture]

Answers

Answer:

6/9

Step-by-step explanation:

there are the possibility that she takes different colors six times in 9 different possible results

The probability that both marbles selected are different colors is 2/3.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, Kaitlyn has a bag with an equal number of red, yellow, and blue marbles.

From tree diagram, we have {RY, RB, RR, YR, YB, YY, BR, BY, BB}

Here, the probability = 6/9

= 2/3

Therefore, the probability that both marbles selected are different colors is 2/3.

One cubic foot of a crushed mineral weighs 160 pounds. How many pounds of the crushed mineral can a container with the dimensions shown hold?



The container can hold__pounds of the crushed mineral.

Answers

3600 pounds

Step-by-step explanation:

One cubic foot of a chemical weighs 60 pounds.

1 ft³ of chemical = 60 pounds

We need to find how many pounds in the container whose dimension 6 ft, 4 ft and 2.5 ft

l = 6 ft

b = 4 ft

h = 2.5 ft

Volume of box = lbh

                        = 6 x 4 x 2.5

                        = 60 ft³

As we are given

1 ft³ of chemical = 60 pounds

60 ft³ of chemical = 60 x 60 = 3600 pounds

Hence, In container contains 3600 pounds of chemicals.

45 rap songs
25 blues
10 R and B
What is a prediction you can make from the type of music Joey will hear when he randomly plays a song from his playlist? (what can we do to try to figure this out?)

A.The song is 3 times as likely to be rap as it is R and B

B.The song is 2 times as likely to be country than it is R and B

C.The song is half as likely to be rap as it is all other songs combined.

Answers

Your answer should be A if not it’s D
I think B would be the correct answer.

County is 20 where R and B is 10, therefore the song would be 2 times as likely t be country than it is R and B.

Carlos bought 80 feet of rope for $17.60. He needs 20 more feet. If the unit price is the same how much will he pay for the extra 20 feet of rope? Show each step of your solution and explain your reasoning.

Answers

Answer:

$4.40

Step-by-step explanation:

ok so this is an instance of proportional relationships, in this case we changed one side of this equation, and now we need to figure out how to change the other side the that the change is made on both sides of the (=)

heres what we know

$17.60 = 80ft.

$??.?? = 20ft.

to help us find the change we can divide the first known side with second known side as shown below

80 / 20 = 4

so now we know that 80 was divided by 4 to get 20, so now we can divide the other side by the same amount to get...

$17.60 / 4 = $4.40

so it costs $4.40 for 20 ft. of rope

EXTRA: just because we can, lets figure out what 1 ft of rope costs using the same method as show above (starting with 20 ft)

20 / 1 = 20

$4.40 / 20 = $0.22

so the rate at wich the rope is sold is 22 cents a foot

It’s $4.40 hopefully this helps

Hey doing-the-homework-at-the-last-minute-student!

Here's how you gotta do it:-

[tex]\frac{5}{6}[/tex] - [tex]\frac{5}{12}[/tex]

Both the denominators should be same to be subtracted.

So, let's multiply [tex]\frac{5}{6}[/tex] with 2 so that its denominator will be 12 as well.

[tex]\frac{5}{6}[/tex] x [tex]\frac{2}{2}[/tex]

[tex]\frac{10}{12}[/tex]

Now, lets subtract this with [tex]\frac{5}{12}[/tex]

[tex]\frac{10}{12}[/tex] - [tex]\frac{5}{12}[/tex]

While subtracting, you don't have to subtract the denominators. Only find the difference between the numerators- 10 and 5.

10-5 is 5.

So,

[tex]\frac{10}{12}[/tex] - [tex]\frac{5}{12}[/tex] = [tex]\frac{5}{12}[/tex]

[tex]\frac{5}{12}[/tex] is the answer!
