Mrs. Peña is taking a group of 50 students on a field trip to the Georgia Aquarium. If 20 of the students are boys, what percent of the students are boys?

Step-by-step explanation:

Assuming c = x, you would substitute 2{(5)^(5)} - 6,

5^5 = 25,

2(25) = 50,

50 - 6 = 44

Answer would be 44, but only if c = x

Answer:

Keith paid $0.25 less than Tony paid.

Step-by-step explanation:

Tony paid ($48 - 10%) = $43.2

Keith paid $42.95.

The difference is Tony paid $0.25 more, or Keith paid $0.25 less.

Answer:

Keith paid $0.25 less than Tony.

Step-by-step explanation:

Tony: 48 x 0.10 = 4.8

48 - 4.8 = $ 43.20 (Tony)

Keith: $ 42.95

43.20 - 42.95 = 0.25

Answer:

it could be 1/8

Line BC is equal to line AD

∴

x + 17 = 3x + 7

x - 3x = 7 - 17

-2x = - 10

-2x / -2 = - 10 / -2

x = 5

AD

3x + 7

3(5) + 7

15 + 7

22

CD

2x - 6

2(5) - 6

10 - 6

4

BC

x + 17

5 + 17

22

AB

Line AB is equal to line CD therefore its length is 4

Answer:

x = 5

AB = 4

BC = 22

CD = 4

AD = 22

Answer & Step-by-step explanation:

Linda walked 3/4 (or 75%) of a track which is 3.5 miles long

Multiply 0.75 by 3.5 to get 2.625 miles (or 2 and 5/8 miles)

38.

We need to multiply the 2 and 3/8 mile track by 2 and a half (2 and 0.5)

1/8 is 0.125  

2/8 is 0.25

3/8 is 0.375

The track is 2.375 miles long.

Multiply 2.375 by 2.5

The track will be 5.9375 miles long after 5 years ( or 5 and 15/16 miles)

Step-by-step explanation:

37) ¾×7/2

21/8 miles = 2⅝miles .

38) (19/8×5/2)+19/8

= 95/16+19/8

= 133/16 = 8 5/16 miles .

hope this helps you.

Answer:

12xto the 3 + 27x squared

Step-by-step explanation:

If X represents the length of the side of a cube, the formula for the surface area of the cube, S =?

solution :

the area of each face of the cube = side × side

= X × X = X²

the cube has 6 similar faces, so the surface area of the cube could be:

S = 6 × X² = 6X²

Answer:

Surface Area = 6 × S²

Step-by-step explanation:

the surface area fo the cube :

if lenght = S, the surface area fo the cube :

SA = 6 × lenght × lenght

SA = 6 × S × S

SA = 6 × S²

Answer: 9 hrs for 45cm of snow to fall

Step-by-step

If 30cm = 6 hrs

Then divide 30/6 to get the unit rate of the amount of snow per hr

Which is 5/1

So 5cm per hr

Then add 30+5+5+5 to get 45

And since we know 5cm equal 1 hr

Add the original amount of hours which is 6 plus 3 ones

Which is 6+1+1+1

In total, it will take 9 hrs for 45cm of snow to fall.

Answer:

12

Answer:

- 5 [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

- 3 [tex]\frac{1}{2}[/tex] - 1 [tex]\frac{5}{6}[/tex] ( change to improper fractions )

= - [tex]\frac{7}{2}[/tex] - [tex]\frac{11}{6}[/tex] ( multiply numerator/denominator of first fraction by 3 )

= - [tex]\frac{7(3)}{2(3)}[/tex] - [tex]\frac{11}{6}[/tex]

= - [tex]\frac{21}{6}[/tex] - [tex]\frac{11}{6}[/tex]

= [tex]\frac{-21-11}{6}[/tex]

= [tex]\frac{-32}{6}[/tex]

= - [tex]\frac{32}{6}[/tex]

= - 5 [tex]\frac{2}{6}[/tex]

= - 5 [tex]\frac{1}{3}[/tex]

Answer:

a-b = 31     (a ≠ b)

Step-by-step explanation:

(3x²-x+1)(px²+qx+1) = ax⁴+bx³+12x² - 6x + 1

3px⁴+(3q-p)x³+(3+p-q)x²+(q-1)x+1 = ax⁴+bx³+12x² - 6x + 1

q-1 = -6             q = -5

3+p-q = 3+p-(-5) = 8+p = 12             p = 4

b = 3q-p = 3*(-5) - 4 = -19

a = 3p = 3*4 = 12

a-b = 12 - (-19) = 31
