Answer:

-9.8

Step-by-step explanation:

I switched them around and made 21.6 a negative and 12.8 a positive. So then it would be like doing 21.6-12.8 which is way easier

21.6

-12.8

____

9.8

Then you convert the 9.8 to a negative.

Answer:

-8.8

Step-by-step explanation:

21.6

-12.8

____

8.8

- because 21 > 12.8

Answer: The length of one side = 1.5 feet

Step-by-step explanation:

GIven: The shape of aquarium is square ( in 3d its cube).

Its volume = 3.375 cubic ft

Volume of cube = [tex](side)^3[/tex]

i.e. side = [tex](Volume)^{\dfrac13}[/tex]

Now, Side of aquarium  = [tex](3.375)^{\frac13} =(1.5^3)^{\frac13} =1.5[/tex]   [[tex]1.5^3=3.375[/tex]]

Hence, the length of one side of aquarium = 1.5 feet

Answer:

The answer is plant B will exceed plant A in two months at the height of 12 centimeters long.

Step-by-step explanation:

Rewrite plant A and B as a linear function

y=3x + 5

y=4x + 4

Then, let x represent the # of months

Next, try to increase the amount by one in both equations until plant B will exceed plant A

pls mark me as brainliest

Answer: go to 10 the over 7 right im pretty sure

Step-by-step explanation:

Answer:

f(7) = - 5

Step-by-step explanation:

Locate x = 7 on the x- axis. Go vertically down to meet the graph, then read the corresponding value of y on the y- axis.

The y- value is - 5

Thus

f(7) = - 5

Answer:

0.14

Step-by-step explanation:

Not sure if this is what you are asking but, 2 pints is 32 ounces. So if you want juice per ounce then you divide 4.48/ 32 which gets you: 0.14. Sorry if this is not what your are looking for.

Answer:

  162 degrees

Step-by-step explanation:

Angles P and F are supplementary, so ...

  3x^2 +12x = 180

  x^2 +4x = 60

  x^2 +4x -60 = 0

  (x +10)(x -6) = 0

The useful value of x that makes this true is x=6.

The measure of angle Q is 3x, so is 3·6 = 18 degrees. The measure of angle S is the supplement to that:

  ∠S = 180° -18° = 162°

Answer:

( - 15, - 16 )

Step-by-step explanation:

Coordinates of midpoint are ( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )

( - 5 + x ) / 2 = - 10 ⇒ x = - 15

( 4 + y ) / 2 = - 6 ⇒ y = - 16

( - 15, - 16 )

Answer:

12.8 %

Step-by-step explanation:

(3200)/(25000) *100

Answer:

Step-by-step explanation:

Step one:

Given data

amount of money earned per hour= $6.25

amount of money made in tips= $8.5

if x represents the number of hours worked and

y represents the total amount earned

The linear function for the total is expressed as

y=mx+c

Step two:

Hence for the situation given the expression for the total is

y=6.25x+8.5

Say Kayla worked for 2 hours

that is x=2, the total she would have earned is

y=6.25(2)+8.5

y=12.5+8.5

y=21

For a 2 hour work, Kayla will make $21

Answer:

a = -40/3

Step-by-step explanation:

(7a - 4) = (4a - 44)

7a - 4 = 4a - 44

7a = 4a - 44 + 4

7a = 4a - 40

7a - 4a = - 40

3a = - 40

3a/3 = -40/3

a = -40/3 or -13.3333 repeating

Answer:

x ≤ 10

Step-by-step explanation:

Answer: below

Step-by-step explanation: You simply need to divide the total amount of sugar (9 lbs) by the amount that you put into each bag (2/3 lb). This expression looks kind of ugly in this form, so let's instead multiply 9 by the reciprocal of 2/3, which in this case is 3/2. The reciprocal of any number is just 1 divided by the number.

Answer:

12

Step-by-step explanation:

Each 3 pounds will need 4 containers

Answer:

7 minutes

Step-by-step explanation:

okay so lets make blocks = x and neighborhood = y

2x + y =10

2x + 4y = 31

multiply the top equation by -1 so we can single out y

-2x - y = -10

2x + 4y = 31

combine the two equations

3y = 21

since the x's have canceled each other out, just divide both sides by 3 to get a single y

y = 7
