Answer:

31.4 cm

62.8 cm

Step-by-step explanation:

The radius of the inner circle is 5 cm.  The line from the edge of the outer circle to the edge of the inner circle is 5 cm.  Assuming that the center of the outer center is the same as the center of the inner circle, the radius of the outer should be 10 cm.

Use the formula for circumference since you have the radius.

Inner circle

C = 2πr

C = 2π(5)

C = 10π

C = 31.4 cm

Outer Circle

C = 2πr

C = 2π(10)

C = 20π

C = 62.8 cm

Answer:

A = 108 m^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2)h  where b1 and b2 are the lengths of the bases

A = 1/2(10+14) (9)

A = 1/2 (24)*9

A = 108 m^2

Answer:

108 meters squared

Step-by-step explanation:

Area = (1/2)(base 1 + base 2)*height

Area= (1/2)(14+10)*9

Area= (1/2)(24)(9)

Area= 12*9

Area= 108 meters squared

First make a sketch

Then use the pythagorean theorem to find the missing sides

Lastly use SOH CAH TOA and plug in you values (Don't forget to simplify)

Answer:

2 n; 36

Step-by-step explanation:

The product of a number and 2 is 2n. When you substitute 18 for n, the solution is 2(18) or 36

Answer:

2 n; 36

Step-by-step explanation:

Let the number be n

The product of a number, n and 2 when n = 18

= 2*n

= 2 * 18

=36

Answer:

8 less then the quotient of 42 and a number

a " quotient " is the result of division

(42 / n ) - 8.....when n = 6

(42/6) - 8 =

7 - 8 =

-1

so when n = 6, the expression = -1

[tex]\frac{d(4d-25)}{40}[/tex]

Step-by-step explanation:

Given: [tex]d+\frac{3}{8}d-2d+\frac{1}{10}d^2[/tex]

To find: the value of given expression in reduced form

Solution:

[tex]d+\frac{3}{8}d-2d+\frac{1}{10}d^2=\frac{d}{1}+\frac{3}{8}d-\frac{2d}{1}+\frac{1}{10}d^2[/tex]

Here, [tex]L.C.M(1,8,1,10)=40[/tex]

( L.C.M of two or more numbers is the smallest positive number that is their multiple )

So,

[tex]d+\frac{3}{8}d-2d+\frac{1}{10}d^2=\frac{d}{1}+\frac{3}{8}d-\frac{2d}{1}+\frac{1}{10}d^2\\=\frac{40d+15d-80d+4d^2}{40}\\=\frac{\left ( 40d+15d-80d \right )+4d^2}{40}\\=\frac{\left ( -25d \right )+4d^2}{40}\\=\frac{4d^2-25d}{40}\\=\frac{d(4d-25)}{40}[/tex]

Answer:

32 minutes

Step-by-step explanation:

Imagine that each person is assigned one wall, and all 8 people begin painting at the same time.

Since everyone will finish painting their assigned wall after 32 minutes, it takes one person 32 minutes to paint one wall.

If we have 12 people and 12 walls, we can again assign one wall to each person.

Everyone will take 32 minutes to paint their assigned wall.

In other words, it takes 32 minutes for 12 people to paint 12 walls.

Answer: $190

Step-by-step explanation:

Normal pay $4 * 40 hours = $160

Overtime $6 * 5 = $30

Answer:

Step-by-step explanation:

Gross wage = Regular wage + overtime wage

Employee works for 45 hours = 40 hours + 5 hour overtime

Gross wage = 4*40 + 6*5

                   = 160 + 30

                  = $ 190

Answer:

V=7500

Step-by-step explanation:

Answer:

if   x = the number of nickles   and     x-34 = the number of dimes                    then .05x + .10(x-34) = 4.85               or          .15x = 8.25               x = 55

So, nickles = x = 55

dimes = (x-34) = 21

55+ 21 = 76 So, that means your answer is C. 76 coins

Step-by-step explanation:

Answer:

the correct answer is C

Step-by-step explanation:

Set the 34 more nickels aside.

--> pairs of 1 nickel & 1 dime each worth 15 cents & a total of $3.15 ($4.85 - $1.70)

315/15 = 21 pairs

--> 21 dimes and 55 nickels

Answer:

24 sandwich combinations

Step-by-step explanation:

To solve this problem, you can do 3x2x4, and you would get 24.

Or, you can do something like this:

1st kind of bread with 1st type of meat and 4 options of cheese = 4 possible combinations

1st kind of bread with 2nd type of meat and 4 options = another 4 possible combinations

Those combinations added together equals 8 combinations. If you multiply this by 3 (3 types of bread), then you would get 24 sandwich combinations, which is the answer.

Hope this helps! :)

Answer:

4a ) Difference ⇒ $ 63.24,

4b ) 4 children

Step-by-step explanation:

4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;

y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,

y = 42.16 + 85.15 ⇒ Combine like terms,

y = 127.31

If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;

y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,

y = 105.4 + 85.15 ⇒ Combine like terms,

y = 190.55

Difference; 190.55 - 127.31 = 63.24,

Solution; Difference ⇒ $ 63.24

4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;

169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,

21.08x = 84.32 ⇒ Divide either side 21.08,

x = 4 children

Solution; 4 children

Step-by-step explanation:

Answer:

the answer is D

The quotient of the given function is [tex]\frac{\sqrt{3}}{2}[/tex]

Given the radical function

Rationalizing the denominator:

[tex]= \dfrac{3\sqrt{8} }{4\sqrt{6} } \times \dfrac{\sqrt{6} }{\sqrt{6} }\\= \dfrac{3\sqrt{8} (\sqrt{6}) }{4\sqrt{6} \cdot \sqrt{6}}\\[/tex]

Multiplying the numerator and denominator:

[tex]=\dfrac{3\sqrt {48}}{4(6)} \\=\dfrac{3(4\sqrt{3})}{24} \\=\dfrac{4\sqrt{3}}{8} \\=\dfrac{\sqrt{3}}{2}[/tex]

Hence the quotient of the given function is [tex]\frac{\sqrt{3}}{2}[/tex]
