Answer:

8 1/4

Step-by-step explanation:

6 3/5 ÷ 0.8

6 3/5 = 33/5

0.8 = 8/10

6 3/5 ÷ 0.8

= 33/5 ÷ 8/10

= 33/5 * 10/8 ( Because multiplication and division are inverse operations)

= 33/4

= 8 1/4

Reggie can line a football field in 120 minutes. Rosalinda can line a football field in 80 minutes. If they work together, how many minutes does it take them to line a football field?a. 40 minutes
b. 80 minutes

d. 240 minutes HELP?!

Answers

Answer:

If they work together, they take 48 minutes to line the football field.

Step-by-step explanation:

Given: Reggie can line a football field in 120 minutes. Rosalinda can line a football field in 80 minutes.

To find : If they work together, how many minutes does it take them to line a football field?

Solution :

If they work together,

Let the number of minutes(x) they take to line the foot ball field.

According to question,

$(1)/(x)=(1)/(120)+(1)/(80)$

$(1)/(x)=(80+120)/(120* 80)$

$(1)/(x)=(200)/(120* 80)$

Cross multiply,

$x=(120* 80)/(200)$

$x=12* 4$

$x=48$

Therefore, If they work together, they take 48 minutes to line the football field.

Answer: If they work together, they can line a football field in 48 minutes.

Step-by-step explanation: Given that Reggie can line a football field in 120 minutes and Rosalinda can line a football field in 80 minutes.

We are to find the number of minutes does it take them to line a football field if they work together.

We have

Time taken by Reggie to line a football field = 120 minutes.

So, in 1 minute, Reggie can line $(1)/(120)$ part of the field.

Time taken by Rosalinda to line a football field = 80 minutes.

So, in 1 minute, Rosalinda can line $(1)/(80)$ part of the field.

Therefore, if they work together, the portion of the football field that they can lie in 1 minute is given by

$(1)/(120)+(1)/(80)\n\n\n=(2+3)/(240)\n\n\n=(5)/(240)\n\n\n=(1)/(48)$

Thus, if they work together, they can line a football field in 48 minutes.

Is 30 a prime number

Answers

No, a prime number is a number that is only divisible by 1 and itself. For example, the numbers 2 and 3.
30 is divisible by 1,2,3,5,6,10,15, and 30.

No it's not beecause 30 has divisors rather than 1 and itself. 30 can be divided by 2 and 3.

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m. Find the exact area of the larger circle
Find the exact area of the smaller circle.
Write an expression to find the exact area of the sidewalk (shaded portion).
Find the approximate area of the sidewalk. Use 3.14 to approximate π.

Find the exact area of the smaller circle. Show your work. (1 point)

Write an expression to find the exact area of the sidewalk (shaded portion). Show your work. (2 points) 11 2 – 9 2 x n

Find the approximate area of the sidewalk. Use 3.14 to approximate π. Show your work. (1 point) 11 2 x 3.14 – 9 2 x 3.14=

Answers

Well first lets find area of the entire circle itself

We have the radius be 11.

Pie x radius^2 = A

11 squared is 121.

So we have:

Pie x 121 = area

Pie is 3.14.

The area of the entire circle is exactly 379.94 m.

Now lets put this off to side and solve the inner circle.

Same thing:

Radius of the inner circle is 9.

Pie x radius^2 = Area

9 squared is 81.

So now:
Pie x 81 = area

Pie is 3.14

3.14 x 81 = exactly 254.34.

The inner pen is exactly 254.34 m

So now knowing :

The whole circle is 379.94
And the inner circle is 254.34

We can subtract the inner circles area from the whole circle and get the area of the outer circle/sidewalk.

379.94 - 254.34 = 125.6

The outer circle/sidewalk is 125.6 m

With this info we can answer your questions.

The exact area of the larger circle is 379.94 m

The exact area of the inner circle is 254.34 m

Expression:
If
Large circle = L
Small circle = S
Sidewalk = W

An expression would be L - S = W

The sidewalk area is exactly 125.6 m

To show your work read what i did above and just show how i did Pie x radius = area.

Hope this helps!

Each interior angle of a regular n-sided polygon is 150 degrees. How many sides does the polygon have?

Answers

The sum of the interior angles of the polygon = (n - 2) x 180 .

(n - 2) x 180 = (n x 150)

180n - 360 = 150n

Add 360 to each side:

180n = 150n + 360

Subtract 150n from each side:

30n = 360

Divide each side by 30 :

n = 12
