Answer:

(r+p)*3

Step-by-step explanation:

You have to add r+p to find out how many dogs samantha walked in a day.

Then you multiply r+p by 3 to find out how much dogs she walked in three days.

So the expression would be (r+p)*3

Answer:

48 cm^3 is the answer.

Answer:

the volume is 48 cm^3

Step-by-step explanation:

if one cube is equal to 1 cm, and the width is 2 cubes, height is 4 cubes, and length is 6 cubes, then you have to convert each measurement to cm. Now we have each measurement:

height = 4 cm

width = 2 cm

length = 6 cm

Next, you have to multiply 2 by 4 (or 2 by 6, it wont matter what order you multiply), which is 8. After that, you have to multiply 8 by 6, which is 48.

Hence, the volume is 48 cm cubed, or cm^3.

Answer:

m<6=77°

Step-by-step explanation:

Because the angles marked 3x+5 and 4x+7 are same side exterior angles, they are supplementary, meaning that

3x+5°+4x+7°=180°

7x+12°=180°

7x=168°

x=24°

Because the angles marked 6 and 3x+5 are corresponding angles, they are congruent, so:

<6=24*3+5

<6=77°

Answer:

The answer is B

Step-by-step explanation:

If you read the other answers you can see that they are all by sixths and not sevenths. And if that was just an error then 9*5=45 making B correct.

Answer:

Answer is 6

Step-by-step explanation:

³/₅+2+1⁴/₅+1³/₅

change 1⁴/₅ and 1³/₅ to improper fraction to become ⁹/₅ and ⁸/₅ respectively

Also change 2 to a fraction to become²/₁

³/₅ + ²/₁ + ⁹/₅ + ⁸/₅ =

L.C.M is 5

Divide each value by 5 i.e ³/₅ + ²/₁ + ⁹/₅ +⁸/₅ =3 + 10 + 9 + 8

                                                                                    5

The answer you get is: ³⁰/₅ you divide to get 6

The answer is 6

Answer:

1) Consider 20%, 20/100

20/100 x 54.65 = 10.93, though rounded to the nearest dollar would be around $11.

2) 54.65(the bill) + 11(the gratuity) = $65.65, is the total cost of the dinner.

Answer:Is it multiple options?

Answer:

the area of a circle is always pi so 3.14159

Step-by-step explanation:

The side length must be 3.454 inches, so the exact area is 11.999 inches.

For a square of side length S, the area is given by:

A = S^2.

In this case, we know that the squares have an area of 12 square inches, replacing that in the area equation we get:

12 in^2 = S^2

If we apply the square root on both sides, we get:

√(12 in^2) = √S^2

3.464 in = S

This is an approximation to the side length, if each side measured this, the exact area would be:

A = (3.464 in)^2 = 11.999 in^2

Which is almost what we wanted to get.

Answer: x = 20

Step-by-step explanation:

We know that the sum of the angles in a triangle is 180 degrees.

Therefore, we can set up an equation:

46 + 71 + 4x - 17 = 180

We can combine like terms:

4x +100 = 180

Subtract 100 from both sides:

4x = 80

Divide both sides by 4:

x = 20

Answer:

A. 36 children tickets

B. The intercepts of this equation represent how many tickets one type of ticket would have sold if the other type of ticket was not bought at all.

Step-by-step explanation:

So lets start with what we know

Adult tickets = $12

Children Ticket = $8

The theater collected $600.

So with this information, we can write down the equation

12x + 8y = 600

Note: x is the variable for the number of adult tickets and y is the variable for the number of children tickets

Find the amount of children tickets sold if 26 adult tickets were sold

So, this problem is trying to make us solve for y, if x = 26. Let's plug in the values and start solving for that value!

Solve for y                 if x = 26

12x + 8y = 600

12(26) + 8y = 600

312 + 8y = 600

-312          -312

         8y = 288

    8y / 8 = 288 / 8

            y = 36

So, we have our answer as y = 36.

Solution Statement:

If 26 adult tickets are sold, 36 children tickets must be sold if the total amount collected was $600.

The intercepts of this equation represent how many tickets one type of ticket would have sold if the other type of ticket was not bought at all.

Answer:

A= 145.12mm^2

Step-by-step explanation:

The diagram shows us a Right angle triangle; so, I use Phythagoras' Theorem, to find length of the base.

c^2 - b^2 = a^2

27^2-12^2 =a^2

585. = a^2

Square root both sides

a = root 585

= 24.18677324

A= bxh/2

= root 585 x 12/2

= 18 root 65

= 145.1206395

A= 145.12mm^2 to 2.d.p

(Haven't rounded up in calculations until the end. Thus, using the exact values of root 585,for example. )

Answer:

Start: Brown feather % is  97% Grey feather % is 3%

End: Brown feather % is  19% Grey feather % is 81%

Step-by-step explanation:

Start:

There is 700 total feather (679+21) so to get to 100(the denominator for percentages) you have to divide by 7

divide each number by 7(679/7 and 21/7)

and you get 97 and 3 which will be your percentages

End:

There is 740 total feather (140+600) so to get to 100(the denominator for percentages) you have to divide by 7.4

divide each number by 7.7(140/7.4 and 600/7.4)

and you get about 19(rounded) and about 81(rounded) which will be your percentages
