Answer:

a) 156.25 cm^2  b) 221.67 cm^2  c) 65.42 cm^2

Step-by-step explanation:

a)

We know that the formula for the area of a quadrilateral is Length x Height (A = LH).

Since the length and height of a square is the same, L = 12.5cm and H = 12.5cm.

So we incorporate our formula for the area of a square into this situation:

A = 12.5 x 12.5

A = 156.25 cm^2

b)

We know that the formula for the area of a circle is Pi x radius squared (A = πr^2).

Since we know that the diameter of the circle is 16.8cm, we will use this to find the radius.

Radius can be found by halving the diameter (r = d/2).

So we incorporate our formula for radius into this situation:

r = 16.8/2

r = 8.4cm

Now that we have our radius, we can find the area of our circle.

So we incorporate our formula for the area of a circle into this situation:

A = π(8.4)^2

A = 221.6707776 = 221.67 cm^2

c)

We can see from the diagram that the shaded portion come mainly from the circle.  So to find the area of the shaded part, we can simply subtract the area of the square, from the area of the circle (A of circle - A of square = Area of shaded part).

So we incorporate our formula for the area of the shaded part into this situation:

A = 221.67 cm^2 - 156.25 cm^2

A = 65.42 cm^2

Answer:

Step-by-step explanation:

1 hour equals 60 minutes

Find out how many pages per minute by dividing 1,520 pages by 60 minutes.

= 25.3333333

Therefore the machine prints 25.333333 pages per minute.

Multiply 25.3333333 by 15 minutes = 380

The machine can print 380 pages in 15 minutes.

You can check your work by finding out how many fifteen minute periods are in an hour (60/15=4), and multiplying 380x4

Since 15x4 is 60 and you can print 1520 pages in 60 minutes, you should be able to multiply 380x4 and get 1520 (spoiler alert! 380x4 is 1,520)

Hope that helped!

Answer:

3/4

Step-by-step explanation:

same but simple

9/12÷3/3 = 3/4

if this helpful pleas give brainliest!

Answer:

3/4  ( [tex]\frac{3}{4}[/tex] )

Step-by-step explanation:

[tex]\frac{9}{12}[/tex] ÷ [tex]\frac{n}{n}[/tex] = [tex]x[/tex]

to find what to divide 9/12 by first, find their factors

9 - 1, 9, and 3

12 - 1, 12, 2, 6, 3, and 4

since both have 1 and 3 in common, divide by 3

so n (the value you're looking for) is 3

n = 3

[tex]\frac{9}{12}[/tex] ÷ [tex]\frac{3}{3}[/tex] = [tex]\frac{3}{4}[/tex]

x = [tex]\frac{3}{4}[/tex]

your answer is [tex]\frac{3}{4}[/tex]

hope this helps:)

Answer:

9.2

Step-by-step explanation:

a^2 + b^2 = c^2 (pythogoras theorem)

7^2 + 6^2 = 85

Square root of 85 = 9.2 ( nearest tenth)

I think this is right if not srry :(

Answer:

Slope = 3/2

Step-by-step explanation:

To find the slope you do:

[tex]\frac{y2-y2}{x2-x1}[/tex]

Plug in any two points:

[tex]\frac{-5-(-2)}{0-2} = \frac{-3}{-2} =\frac{3}{2}[/tex]

X=14

Step-by-step explanation:

x/7= 48/24

Or,24x=336

Or,x=336/24

Answer:

My explanation is below.

Step-by-step explanation:

rolling a six sided die and getting 7 = impossible

This is because a six sided die doesn’t even have the number 7 on it.

Randomly selecting a girl from a team of 14 boys and 4 girls = unlikely

This is because, if there are 14 boys and 4 girls, the girls have a lower chance of getting picked.

Randomly selecting a short straw from a set of 12 short straws and 12 long straws = neither likely nor unlikely

This is because the chance of picking a long straw is 12/24 and the chance of picking a short straw is 12/24 so it’s equal or neither unlikely or likely since you have a equal chance of picking either one.

Picking a bird from a list of 20 bird species and 6 other animals = likely

This is likely because, 20 is more than 6 and because there are 20 birds and 6 other animals, the birds are more likely.

Answer:

A

Answer:

Step-by-step explanation:

PERIMETER = 1/3 + 1/3 + 1/2 + 1/2 = 2/3 + 1 = 1 2/3 miles for 1 LAP.

For 2 LAPS, 2 x 1 2/3 = (2 x 1) + 2(2/3) = 2 + 4/3 = 2 + 1 1/3 = 3 1/3 miles

Or, 2 x 1 2/3 = 6/3 x 5/3 = 30/9 = 3 3/9 = 3 1/3 miles

Or, 2/1 x 5/3 = 10/3 =   3 1/3 miles

ANSWER: MORE THAN 3 MILES

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

Explanation:

We're given a 1/3 by 1/2 rectangle. The perimeter is:

P = 2(L+W)

P = 2(1/3+1/2)

P = 2(2/6+3/6)

P = 2(5/6)

P = 10/6

P = 5/3

The rectangle has a perimeter of 5/3 miles, which is equivalent to the mixed number of 1 & 2/3.

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

If Shayna and her dog walked the perimeter once, then the answer would be "less than 3 miles".

However, they walked around the park twice. We'll need to double the result.

2*(5/3) = 10/3 = 3 & 1/3

Therefore, they walked more than 3 miles.

Answer:

All of the lunch choices are not equally as likely.

Step-by-step explanation:

Of the 160 students:

21 brought lunch from home = 21/160 = 0.13125

103 purchased lunch = 103/160 =  0.64375

36 lunch + ice cream = 36/160 = 0.225

The probability = what type of lunch a student brings / student population

I hope this helps! Let me know if you have any further questions.

Step-by-step explanation:

you do know that 1 cm = 10 mm, right ?

so,

6 cm = 6×1 cm = 6×10 mm = 60 mm

and that is the ultra-ultra long form of doing this ...

Answer:

60mm

Step-by-step explanation:

This is conversion, so, to find this, we will have to convert 6cm to milimeters.

So [tex]6cm *10mm=60mm[/tex]

[tex]Hello[/tex] [tex]There![/tex]

  We are asked to find the value of n in the equation [tex]\bold{\displaystyle\frac{n}{8} =\frac{11}{5}}[/tex].

It's not hard, I promise! I am going to take you through a few steps, and we'll find the answer.

Are you ready? Then let's begin... :)

[tex]Procedure:[/tex]

First, we need to multiply both sides by the denominator of n/8, which is 8:

[tex]n/8*8=(11/5)*8[/tex]

On the left side of the equal sign, the 8's cancel, leaving us with n.

[tex]n=(11/5)*8[/tex]

We can write 8 as 8/1. Now we multiply 11 times 8 and 5 times 1:

[tex]n=(11*8/5*1)[/tex]

Which is the same as

[tex]n=88/5[/tex]

▲ this answer is already in it's simplest form, we can't simplify it further

Answer:

180

Step-by-step explanation:

If supplies cost 54$ and thats 30% of the total cost, that means you would divide 54 by 3 and that would be 18. Then you would times 18 by 10 to get your final answer: 180$. The reason you would times 18 by 10 is because 18 is 10% percent of 100% and 10 times 10 is 100.

Answer:

Factorial

Step-by-step explanation:

Factorial: Denoted by the exclamation mark (!). Factorial means to multiply by decreasing positive integers. For example, 5! = 5 ∗ 4 ∗ 3 ∗ 2 ∗ 1 = 120.

Hope this helped you<33

ok finally the answer was

(!). 4! simply means that we are taking the product of 4×3×2×1. See some examples below: 1! = 1 2! = 2×1 = 2
