Find the volume of the following figure.

6 cm3
7 cm3
8 cm3
5 cm3

Answer:

c=42

Step-by-step explanation:

First you would find out how much you would add to 45 to give you 66. Which is 21. Then you double it, so when you put it over the two it looks like this 42/2. So when you reduce the fraction you get 21. Hence 21+45=66.

Hope this helps!

Answer:

C = 42

Step-by-step explanation:

½ c + 45 = 66

½ c + 45 − 45 = 66 − 45

2 × (½ c) = 2 × 21

C = 42

Answer:

Mr. Johnson completed his travel in 15 minutes. But Mrs. Johnson leaves 10 minutes after he does. And to add her 12 minutes travel time, that means Mrs. Johnson will arrive in 22minutes.

Step-by-step explanation:

First, we need to find the distance (d) that Mr. Johnson traveled to be able to compute Mrs. Johnson's travel time.

To be able to do that, use the formula d = (s)(t).

d = (80miles/hr)(15mins)

d = (80miles/hr)(0.25hr)

d = 20 miles

Now that we know the distance from Cambridge to Newton, we can use this value to calculate the time Mrs. Johnson needs to complete her travel.

Using the formula t = (d)/(s);

t = (20miles)/(100miles/hr); we get:

t = 0.2hr or 12minutes

Answer:

8( 3 + 7)

Step-by-step explanation:

I prommise this one is correct

8 is the GCF of 24 and 56

if you mutiply 3 by 8 it would equal 24

and if you mutiply 7 by 8 it would equal 56

which would leave you with 24+ 56

Answer:

8(3+7)

Step-by-step explanation:

First we list the factors of 24:

1,2,3,4,6,8,12,24

Now we list the factors of 56:

1,2,4,7,8,14,28,56

As we can see 8 is the highest number in both lists so this would mean a = 8

To factor 24+56 to 8(b+c) :

We do 24÷8 = 3 = b

and 56÷8 = 7 = c

So our final answer is 8(3+7)

Answer:

[tex]V = \pi (2.5)^2h[/tex]

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

[tex]V = \pi (2.5)^2h[/tex]

Answer:

The cost of the rides are 3 tickets

And 1 ticket per game

The ride and game cost 3 tickets and 1 ticket for each respectively.

Step-by-step explanation:

Step 1 of 5

Let a be the number of tickets per ride costs. And b be the number of tickets per game costs.Thus from the given, we get the equations. For Scott, 5a+4b=19    For Isaac,  7a​+2b=23

Step 2 of 5

Multiplying the equation 2 by 2, we get  ​5a+4b=19→1  14a+4b=46→2​

Step 3 of 5

By subtracting both the equations, we get

(−)​5a+4b=1914a+4b=46​          

_____________        

−9a      =−27                  

 ​a=−27−9⇒a=3​

Step 4 of 5

Substituting the above value in the equation 1, we get​5(3)+4b=1915+4b=194b=19−154b=4b=44⇒b=1​

Step 5 of 5

The solution is (3,1).The cost of the rides is 3 tickets per ride.The cost of the games is 1 ticket per game.

sorry its really confusing this how I was taught tho.

Answer:

223.25 - 11.25 - 26.50p = 0

p = 8

Step-by-step explanation:

223.25 - 11.25 - 26.50p = 0

212 - 26.50p = 0

-26.50p = -212

26.50p = 212

p = 212/26.50

p = 8

Answer:

answer is 300m/30min

Step-by-step explanation:

300\10=30

Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.

Using the expression Time = distance / speed.

Given that;

Time = distance / speed

Time = 300m / 10m/min

Time = 30 minutes

Given the speed of the submarine, the total time it will take to cover the the given distance is 30 minutes.

Answer:

Step-by-step explanation:

2.

area= length x width

area = 5.4 x 5.4 = 29.16 cm^2

perimeter is adding up all the sides

perimeter= 5.4+5.4+5.4+5.4 = 21.6 cm

1. area= 7.4 x 5.1 = 37.74 yds^2

perimeter= 7.4+7.4+5.1+5.1 = 25 yds

Directions

Open the compass legs to some radius more than 1/2 the length of WX. It does not matter what the exact value as long as it is more than 1/2 way.

Put the pin end on X and draw an arc with the penciled end. Make sure that the arc you are drawing is both above and below the line WX.

Transfer the pin end to W and draw another arc so that the new arc intersects the first arc drawn from x. Make sure that the new arc is above and below the line WX

With the straight edge as a guide, draw a line between the two intersected arcs. Where lines intersect each other is where the perpendicular bisector intersects WX

Answer:

28/206 or the simplest form would be 14/103

Step-by-step explanation:

Basically, you add the skull, face, and ears and you get a number which is 28 and the total of the bones is 206 if you add all of the numbers and if you want to simplify you divide both of the numbers/the numerator and denominator by 2 and you get 14/103.

The value of fraction of the bones in a typical human body are in the skull, face, and ears is,

⇒ 28 / 206

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

The table shown the bones in a typical human body.

Hence, Number of the skull, face, and ears bones is,

⇒ 8 + 14 + 6

⇒ 28

And, Total number of bones is,

⇒ 206

Thus, The value of fraction of the bones in a typical human body are in the skull, face, and ears is,

⇒ 28 / 206
