Answer:

0.609375 or 39/64

decimal ------- fraction

Step-by-step explanation:

Answer:

E    see below

Step-by-step explanation:

When dividing two fractions, you flip the second fraction over then multiply.

So the equation would then be:

3xy (2 + y)           ab

---------------  X   --------------

     2ab                3xy

The 3xy on top and bottom cancel each other out.  The ab on top and bottom cancel each other out.

So you are left with:

2 + y

-------

   2

Answer: Number E is correct.

Step-by-step explanation:

division becomes multiplication and turns upside down. ab cuts ab and 2 remains as denominator. 3xy cuts 3xy and 2+y remains as numerator. Therefore the answer obtained is 2+y/2.

I Had A Problem In This Too Lol Here Was Correct For Me

Step-by-step explanation:

Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Answer:

slope = 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}x_{1} }[/tex]

with (x₁, y₁ ) = (- 10, 9 ) and (x₂, y₂ ) = (-12, 7 )

m = [tex]\frac{7-9}{-12-(-10)}[/tex] = [tex]\frac{-2}{-12+10}[/tex] = [tex]\frac{-2}{-2}[/tex] = 1

Answer:

7) No

8) Yes

Step-by-step explanation:

7) 15 + 2y = -12 - 4y when y = -0.5

15 + (2*-0.5) = -12 - (4*-0.5)

15 + -1 = -12 - (-2)

15 - 1 = -12 + 2

14 = -10

The numbers are different on both sides so -0.5 is not a solution

8) 5 - 2( 3x + 5 ) = 3 - 10x when x = 2

5 - 2( (3*2) + 5 ) = 3 - (10*2)

5 - 2( 6 + 5 ) = 3 - 20

5 - 2*11 = 3 - 20

5 - 22 = 3 - 20

-17 = -17

The numbers are similar on both sides so 2 is a solution

Answer:

2110.08 meters

Step-by-step explanation:

find the circumference of the wheel

Divide 84 by 2 to find the radius.

84/2=42

C=2πr

C=2(3.14)(42)

C=263.76 cm

263.76*800=211008cm

Divide by 100 to convert to meters

211008/100=2110.08

2110.08 Meters

Answer:

It is given

4x+3y=24

We can also write it as

3y=24−4x

 y=324−4x

Substituting x=0 in the given equation

 y=324−4(0)

 So we get 

 y=324

 By division 

 y=8 

 Substituting x=3 in the given equation 

 y=324−4(3)

 So we get

 y=312

 y=4

Step-by-step explanation:

The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).

The expressions that represent the perimeter of the square are  p = 4(6m-3) and p = 24m - 12. And p = 24m - 12 is the simplest form of the expression.

A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.

Given:

The side of the square is 6m-3 unit.

And all the sides of the squares are equal.

And the perimeter p of the square is,

= the sum of all the sides.

p = 4 x one side.

p = 4(6m-3)

The above expression represents the perimeter of the given square.

Simplifying,

p = 24m - 12

This is the simplest form of the expression.

Therefore, the required expression are p = 4(6m-3) and p = 24m - 12.

Answer:

10

Step-by-step explanation:

Use Pythagorean theorem,

Base² + altitude²= hypotenuse²

8² + altitude² = (2√41)²

64 + altitude² = 2²*(√41)²              {(√41)² = √41*√41 = 41}

64 +altitude² = 4 * 41

64 +altitude² = 164

      altitude² = 164 - 64

      altitude² = 100

      altitude = √100 = 10

Answer:

[tex]s(u(2)) = 135[/tex]

Step-by-step explanation:

[tex]u(t) = 7t - 2 \\ u(2) = 7(2) - 2 \\ u(2) = 14 - 2 \\ u(2) = 12 \\ \\ s(t) = {t}^{2} - 9 \\ s(u(2)) = {(12)}^{2} - 9 \\ s(u(2)) = 144 - 9 \\ \\ s(u(2)) = 135[/tex]

I hope I helped you^_^

For the functions u(t) = 7t - 2 and s(t) = t² - 9. s(u(2)) = 135

A function is a mathematical equation that shows the relationship between two variables.

For the functions u(t) = 7t - 2 and s(t) = t² - 9.To find what is s(u(2)), we proceed as follows.

Since u(t) = 7t - 2. Then u(2) is evaluated when t = 2. So, we have that

u(t) = 7t - 2

u(2) = 7(2) - 2

u(2) = 14 - 2

u(2) = 12

Now, since u(2) = 12 and s(t) = t² - 9

s(u(2)) is evaluated as follows

s(t) = t² - 9

s(u(2)) = 12² - 9

s(u(2)) = 144 - 9

s(u(2)) = 135

So, s(u(2)) = 135
