How do we multiply numbers

1 answer:

7 0

To multiply a number, simply take a number (Let's say 4) and another number (Let's say 3). If you multiply 4 by 3, you are simply taking the number 4, and adding it to itself 3 times (4 + 4 + 4).

I hope this makes sense, please tell me if you need some more information.

Hope this helps!

Answer:

Number of hours= 13.61 hours

Step-by-step explanation:

Giving the following information:

Mr. Halloway knows that it is about 885 miles to their destination.

Average speed= 65 miles per hour

To calculate the number of hours to be drive, we need to use the following formula:

Number of hours= total miles / miles per hour

Number of hours= 885/65

Number of hours= 13.61 hours

An Indian tepee is a conical tent. Find the number of cubic feet of air in a teepee 10 ft. in diameter and 12 ft. high.

vampirchik [111]

Surface Area of a cone is

pi * r * s + pi * r^2 

s is the side length, since you have 10 ft diameter, you know radius is 5. And since height is 12. With this, you have a 5-12-13 triangle, and s=13. 

so 

pi * 5 * 14 + pi * 5^2 = 95 pi or 298.3 

divide 298.3 by 15 and you get 19.88, you round up, so 20 is the answer

Help this is due tomorrow please! Carter has 88 feet of fencing to enclose a dog pen in his yard. He is trying to decide whether

svet-max [94.6K]

<h3>Answer:</h3>

The circle makes the larger area

The difference in the two areas is roughly 132.2479 square feet.

=================================================

Explanation:

If Carter decides to go for a circle, then 88 is the circumference, which is the distance around the circle (aka perimeter of the circle).

Use this to find the radius needed

C = 2*pi*r

r = C/(2pi)

r = 88/(2pi)

r = 44/pi

I'll leave it in exact form rather than approximate it.

Once we know the radius, we can find the area of the circle.

A = pi*r^2

A = pi(44/pi)^2

A = pi*(1936/(pi^2))

A = 1936/pi

A = 616.247939651819 approximately

I used my calculator's stored version of pi to compute the area in the final step.

We'll be comparing this number later, so hold onto it for now.

-------------------------------------

If Carter instead decides for a square, then 88 is the perimeter since it's the amount of fencing he has to work with.

Divide it into 4 pieces to find the length of each side of the square (all sides are equal in a square)

88/4 = 22

Each side is 22 feet

The area of this square is (22)^2 = 22*22 = 484 square feet

--------------------------------------

Summary:

If Carter goes for a circular enclosure, then he gets roughly 616.2479 square feet.
The square enclosure only gets him exactly 484 square feet.

The circle wins in terms of larger area.

The difference being roughly 616.2479 - 484 = 132.2479 square feet.

Joan works on commission for a furniture store. She gets a base pay of $85 a day plus 6 percent of the

podryga [215]

Answer:

Correct expression: 85 + 0.06(t - 400)

Correct earnings: $91

Step-by-step explanation:

The expression Joan wrote is incorrect because instead, $85, she put $400 as her base salary. The correct expression would be 85 + 0.06(t - 400), where 85 is her base pay in dollars, and t - 400 represents her sales in dollars exceeding $400.

If Joan's sales were $500, she would not make $424.90, but

85 + 0.06(t - 400)

85 + 0.06(500 - 400)

85 + 0.06(100)

85 + 6

$91

Hope this helps.

Cheers,

Andy

Someone please help! You have to show your work.

40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
