Solve for y: 5/y=1/0.5

Answer: 2(3)

Step-by-step explanation:

Answer: \(y = \frac{1}{4} x - 1\)

Step-by-step explanation: In general, know that the equation for a linear graph is \(y = mx + b\), where

In our case,

Answer:

(x - 3)(x + 3)(x² + 9)

Step-by-step explanation:

Step 1: Difference of Squares

(x² - 9)(x² + 9)

Step 2: Difference of Squares within Difference of Squares

(x - 3)(x + 3)(x² + 9)

*You can't factor x² + 9 because it has no real roots. You can factor it to have complex roots (imaginary number i).

Answer:

(x+3)(x+3)(x²-9)

Answer:

So the four consecutive odd integers are: 51 , 53 , 55 and 57

Step-by-step explanation:

I wish i can help

Answer:

- 15, - 17, - 19, - 21

Step-by-step explanation:

let the 4 consecutive odd numbers be

n , n + 2, n + 4, n + 6 ( that is 2 between each odd number ) , then

n + n + 2 + n + 4 + n + 6 = - 72

4n + 12 = - 72 ( subtract 12 from both sides )

4n = - 84 ( divide both sides by 4 )

n = - 21 , then

n + 2 = - 21 + 2 = - 19

n + 4 = - 21 + 4 = - 17

n + 6 = - 21 + 6 = - 15

The 4 numbers are - 15, - 17, - 19, - 21

Answer:

a.3(5x-8)

b.201miles

Step-by-step explanation:

A.because per hour (5x-8)miles so 3hours travel distance 3(5x-8)

B.3(5x-8

=3x (5x15-8)    15x5=75

=3x(75-8)         75-8=67

=3x67                67x3=201

=201miles

Hope this helps!

Answer:

A sequence is a function whose domain is the set of natural numbers or a subset of the natural numbers. We usually use the symbol an to represent a sequence, where n is a natural number and an is the value of the function on n.

Answer:

1=y/x

Step-by-step explanation:

Because 1/4xy=x+1/4x=1=y/x

Answer:

525

Step-by-step explanation:

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Step-by-step explanation:

The difference beteen 9.2 ounces and 8.1 ounces is  1.1 ounces

   and the difference in price is   .49

       so 1.1 ounces cost .49

           $ .49 / 1.1 oz = $  .445  per ounce

Then Reid's bowl should cost   7.8 oz  * $ .445 / oz = $3.47

\(\\ \rm\longmapsto \dfrac{675^5}{675^8}\)

\(\\ \rm\longmapsto 675^{5-8}\)

\(\\ \rm\longmapsto 675^{-3}\)

Or

\(\\ \rm\longmapsto \dfrac{1}{675^3}\)

Answer:

• from law of indices:

\( \dashrightarrow \: { \tt{ \frac{a {}^{n} }{ {a}^{m} } = {a}^{(n - m)} }} \\ \)

so, • a → 675

• n → 5

• m → 8

\(\dashrightarrow\:{ \tt{ \frac{ {675}^{5} }{675 {}^{8} } = {675}^{(5 - 8)} }} \\ \\ = { \boxed{ \boxed{ \tt{ {675}^{ - 3} }}}}\)

Step-by-step explanation:

I am unsure about number 1, but for number 4, you have to fund the unit rate.

Answer:

Answer for Number 1: 54 1/2

Answer for Number 4: $2.36

Step-by-step explanation:

Explanation for number 1:

    1.  length x width = area right? So area divided by length = width!

        159 3/8 divided by 18 3/4 = 8 1/2

    2. width + width + length + length = perimeter right? Now you know the

        width,  you can do...

         8 1/2 + 8 1/2 + 18 3/4 + 18 3/4 = 54 1/2

Explanation for number 4:

    1.  You know that 4 cup = 1 quart right?

        9.44 = 1 quart

    2. So you divide it:

        9.44 / 4 = $2.36

Answer:

Step-by-step explanation: Each cube has a total of 6 sides. In the model, the top cube has 1 "hidden" side/1 side that is not exposed to the paint, the bottom middle has 1 "hidden" side, the right bottom cube has 1 "hidden" side, and so does the left. Adding up all the sides that are not exposed to the paint, there is a total of 4 white sides.

We find on calculator and in workings - / -  does =  positive

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:    Find the area of the trapezoid!

= 1012 meters

Step-by-step explanation:

Surface Area = 2×(12×13 + 12×14 + 13×14)

Hopefully this helps you!

-Keira

Answer:

169 mi²

Step-by-step explanation:

To find the area of a trapezoid, use this formula:

\(A=\frac{a+b}{2} h\)

"a" and "b" represent the two bases (12 mi and 14 mi), and the "h" stands for height (13 mi). Insert these values into the equation.

\(A=\frac{12+14}{2} 13\)

\(A=\frac{26}{2} 13\)

\(A=13 * 13\\= 169\)

Therefore, A = 169. :)

13 1/4

4.5 into a fraction is 4 1/2. 4 1/2 + 8 3/4 is 13 1/4 feet.

Answer:

The answer is d. 13 1/4 feet PLEASE MARK BRAINLIEST

Step-by-step explanation:

the 8 feet plus the 4 feet from the 4.5 feet makes 12 feet plus the fractions so 8 inches is 1/4 feet and 8 inches plus 5 inches on the 4.5 feet makes 13 inches which is 13 1/4 feet so 8 3/4 feet + 4.5 feet = 13 1/4 feet

Answer:

A. {2. 5(3m - 6)} and {4. 15 ( m - 2 )}

B. 1. 5m + 5n + 5p

   2. 15z

   3. 20d - 12

Step-by-step explanation:

A.

1. 3 * 5m = 15m

  3 * -6 = -18

 15m - 18 = 15 - 30 (false)

2. 5 * 3m = 15m

   5 * -6 = -30

  15m - 30 = 15m - 30 (true)

3. 1m * 15 = 15m

   1m * -30m = -30m²

  15m * -30m² = 15m - 30m (false)

4. 15 * m = 15m

   15 * -2 = -30

  15m - 30 = 15m - 30 (true)

5.  3 * 5m = 15m

    3 * 10 = 30

   15m + 30 = 15m - 30 (false)

B.

1. (5 * m) + (5 * n) + ( 5 * p) = 5m + 5n + 5p

2. (z * 4) + (z * 5) + (z * 6) = 4z + 5z + 6z Simplify -->15z  

3. (4 * 5d) - (4 * 3) = 20d - 12

Answer:

10 3/4

Step-by-step explanation:

\(x + \frac{7}{4} = - \frac{5}{2} \times - \frac{5}{1} \\ x = \frac{25}{2} - \frac{7}{4} \\ x = \frac{43}{4} \\ x = 10 + \frac{3}{4} \)

Answer:

B  -4

Step-by-step explanation:

-1.5(4 - r) = -12

Distribute -1.5.

-6 + 1.5r = -12

Add 6 to both sides.

1.5r = -6

Divide both sides by 1.5.

r = -4

Your answer is -4.

Answer:

r = -4

Step-by-step explanation:

-1.5(4-r)=-12

Divide each side by -1.5

-1.5 / -1.5  *(4-r)=-12 / -1.5

(4-r) =8

Subtract 4 from each side

4-r-4 = 8-4

-r = 4

Divide each side by -1

-r/-1 = 4/-1

r = -4

Answer:

(D) |-6 - 36|

Step-by-step explanation:

First, we should find the rise in temperature. -6 ia 6 away from 0. 36 is 36 away from 0. The change in temperature is 42ºF.

What I just did was find the absolute value of both numbers. Answer D Provides the absolute value of both 36 and 6.

|-6 -36| = |-42| = 42ºF change

This equation fits the change so it is the correct answer.

Answer:

In vertex form: y = 1(x - (-3))² + 7

Vertex: Minimum (-3, 7)

Explanation:

Vertex form: y = a(x - h)² + k

Completing square (rules) :

1st rule: (x + d)² = x² + 2dx + d²    and   (x - d)² = x² - 2dx + d²

2nd rule: x² + 2dx = (x + d)² - d²   and  x² - 2dx = (x - d)² - d²

Given equation:

y = x² + 6x + 16

y = x² + 2(3)x + 3² + 7

y = (x + 3)² + 7

Into vertex form:

y = 1(x - (-3))² + 7

From this identify:

a = 1, h = -3, k = 7

Solution, vertex of this equation: Minimum (-3, 7)

Answer:

It is 12boys:13girls

Step-by-step explanation:

The total is 250 out of which 130 are girls. So it is 250-130 which is 120boys. Now to find the ratio it is 120:130 which in its simplest form is 12 boys:13 girls.
