how many minutes of practice does one picture represent

Answer:

68.75

Step-by-step explanation:

Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.  

13.6 + 5.9= 19.5

19.5 + 8 = 27.5

27.5 x 5 = 137.5

137.5 x 1/2 = 68.75

The answer to your question would be B. 10/15 and 14/21.

10/15 in simplest form is 2/3

14/21 in simplest form is 2/3

Answer:

Option D : t = 5s + s/2 is the correct answer.

Step-by-step explanation:

Given that:

t = Combined weight of water and food

s = weight of the snail

Water drank by snail = 5s

Food ate by snail = s/2

Combined weight = Weight of water + Food

t = 5s + s/2

Hence,

Option D : t = 5s + s/2 is the correct answer.

Answer:

When yeast cells are reproducing rapidly during beer or wine production, the oxygen is used up. ... Yeast respires using glucose in the sugar that was added to the dough. Bubbles of carbon dioxide make the bread rise. The alcohol that's produced evaporates as the bread is baked.

Answer:

y =  -2x + 10

Step-by-step explanation:

The equation in point slope form is expressed using the equation

y - y1 = m(x - x1) where;

m is the slope = -2

(x1, y1) is the point on the line = (4,2)

Substitute into the formula:

y - 2 = -2(x - 4)

y -2 = -2x + 8

y = -2x +8 +2

y = -2x + 10

Hence the required equation of the line is y =  -2x + 10

Step-by-step explanation:

Answer:

-2 i think

Step-by-step explanation:

Answer:

Use the given functions to establish and reduce u (4)

x=x2+1=x=1+i√32,1−i√32

w=x=1+i√32,1−i√32

u(4)=4u

Step-by-step explanation:

Answer:

5, probably

Step-by-step explanation:

you are looking for the function w(u(4)). you need to find u(x) first when x=4 so solve for u(4)=-x+2 so u(4)=-4+2=-2. now plug this -2 value into the function w(x) so w(-2)=-2^2+1 so basically =4+1 and I think that is probably 5 maybe the value of w(u(4))=5

Answer:

C

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 32² = 48²

x² + 1024 = 2304 ( subtract 1024 from both sides )

x² = 1280 ( take the square root of both sides )

x = [tex]\sqrt{1280}[/tex]

  = [tex]\sqrt{256(5)}[/tex]

   = [tex]\sqrt{256}[/tex] × [tex]\sqrt{5}[/tex]

   = 16[tex]\sqrt{5}[/tex] → C

Answer:

  D.  (-3, -2)

Step-by-step explanation:

The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.

Using (x, y) = (-2, -3):

  x = y -1  ⇒  -2 = -3 -1 . . . . False

Using (x, y) = (-3, -2):

  x = y -1  ⇒  -3 = -2 -1 . . . .True

  2x = 3y  ⇒  2(-3) = 3(-2) . . . . True

The solution is (-3, -2).

__

If you'd like to solve the set of equations, substitution for x works nicely.

  2(y -1) = 3y

  2y -2 = 3y . . eliminate parentheses

  -2 = y . . . . . . subtract 2y

  x = -2 -1 = -3

The solution is (x, y) = (-3, -2).

Answer:

(x,y)=(3,5)

Step-by-step explanation:

Answer:

x = 3

y = 5

Step-by-step explanation:

*tip = chose a variable and get by itself one side and then plug it into the other equation

3x + y = 14

y = -3x + 14

2x - 6(-3x + 14) = -24

2x + 18x - 84 = -24

20x = 60

x = 3

3(3) + y = 14

9 + y = 14

y = 5

Answer Step-by-step explanation:

Let z = 3x +2. Then the equivalent quadratic equation can be written as

 z² +7z -8 = 0

_____

This can be factored as

 (z -1)(z +8) = 0

which has solutions

 z = {1, -8}.

Then the corresponding values of x are found from

 z = 3x +2

 z -2 = 3x

 (z -2)/3 = x

For z = 1,

 (1 -2)/3 = x = -1/3

For z = -8

 (-8 -2)/3 = x = -10/3

Answer:

Square

x = 2

y = 1

Step-by-step explanation:

Measures of all ll sides of a square are equal.

Therefore,

5x - 4 = 3x

5x - 3x = 4

2x = 4

x = 4/2

x = 2

5y + 1 = 2y + 4

5y - 2y = 4 - 1

3y = 3

y = 3/3

y = 1

Answer:

7 y and 8x first add the 2 number with y together and then you take away the 1 with the x and then you add both of them together
