Answer:

12 quarters

Step-by-step explanation:

number of quarters ---------x

number of dimes ------------y

therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1

              0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2

equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12

there are 12 quarters

Answer:

8 and 5

Step-by-step explanation:

Let the number of feet added = x

(x + 6) ( x + 3) = 40               Remove the brackets

x^2 + 6x + 3x + 18 = 40        Combine like terms on the left

x^2 + 9x + 18 = 40                Subtract 18 from both sides

               -18    -18

x^2 + 9x = 22                        Subtract 22 from both sides

x^2 + 9x - 22 = 0

This quadratic factors

(x + 11)(x - 2)

x + 11 = 0

x = - 11 which makes not sense.

x - 2 = 0

x = 2

The answer is x = 2

Check

6+2 = 8

3+2 = 5

8 * 5 = 4- just as it should.

Answer:

Option C would be correct!

Step-by-step explanation:

Since,

For Option A 8(2r) would be 16r not 10r

For Option B 6r + 3 would be 6r + 3 not 9r

For Option C 9(3r - 4) would be 27r - 36, and that indeed is the answer

For Option D r + r + r + r + r would be 5r not r⁵

Hope this helps!

Answer:

you should find the perimeter using rectrangle formula

Step-by-step explanation:

perimeter of rectrangle-2 (l+B)

length=22cm breadth=20cm

perimeter=2 (22+20)

=2 X 42

=84

Answer:

21

Step-by-step explanation:

First, you put all of the possiblities for the kitchen.

K1

K2

K3

K4

K5

K6

K7

Then, you multiply  7 by each room which would be 3 so,

3 * 7 = 21

So, 21 is probably your answer.

Lastly, have a great day!

There are 210 color arrangements possible

The number of rooms (r) in the house is given as:

[tex]r = 3[/tex] ---- i.e. the kitchen, dining room, and living room

The number of available colors (n) to select from is also given as:

[tex]n = 7[/tex]

The possible color arrangement is calculated using the following permutation formula

[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]

So, we have:

[tex]^7P_3 = \frac{7!}{(7 - 3)!}[/tex]

Remove bracket

[tex]^7P_3 = \frac{7!}{4!}[/tex]

Expand the numerator

[tex]^7P_3 = \frac{7 \times 6 \times 5 \times 4!}{4!}[/tex]

[tex]^7P_3 = 7 \times 6 \times 5[/tex]

[tex]^7P_3 = 210[/tex]

Hence, there are 210 color arrangements possible

77 degrees

Step-by-step explanation:

The triangles are similar so all the angles would be congruent.
