Step-by-step explanation:

260÷45=5.77

Round and it ends up being 6

Answer:

5

Step-by-step explanation:

45 * 120% = 54

260/54 = ~5 (rounded, as you cannot sell a fraction of a coat AND you must receive AT LEAST $260)

In order to sell jackets at this price and end with at least $260, you must sell 5 jackets.

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: 12 degrees or 11 5/5 or 60/5

Step-by-step explanation:

Since the temperature is rising 2 2/5 per 1/5 of an hour we just need to multiply 2 2/5 times 5 because 5/5 would equal the whole hour. In order to multiply easier you can change 2 2/5 to an improper fraction by multiplying the whole number with the denominator and then adding the numerator. Which you should get 12/5 next change 5 to a fraction which would be 5/1. 5 times 12 is 60 and 5 times 1 is 5. You get 60/5 which if divided is 12.

For the number line you just have to find 1/5 and 2 2/5 on it and mark it.

Answer:

x=3 y=-1

Step-by-step explanation:

substitute into one of the equations: 4x+2x-7=11

rearrange unknown terms to the left side of the equation: 4x+2x=11+7

combine like terms: 6x=18

divide both sides by x: x=18/6

calculate to product: x=3

Same thing for y:

y=2x3-7

y=6-7

y=-1

Solution:

x=3

y=-1

Answer: -6/5

Step-by-step explanation:

Multiplicative inverse simply is another word for 'reciprocal'.

A reciprocal is the fraction upside down, or inverted.

Knowing this, let's convert -5/6.

-5/6 becomes -6/5, and you don't do anything about the negative sign.

Answer:

Minimum: 6

Lower Quartile (Q1): 9

Median (Q2): 15

Upper Quartile (Q3): 26

Maximum: 34

Interquartile Range: 17

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

Answer:

Crayola Classic: 5 Packs; Crayola Tropical: 4 Packs

Step-by-step explanation:

Keep multiplying by both until you get a number equal to eachother

1. 8 x 2 = 16,  10 x 2 = 20

2. 8 x 3 = 24, 10 x 3 = 30

You may notice that the numbers are getting farther apart. This is normal because the boxes are not equal and are getting multiplied further. That means that your answer will have different factors in both the equations.

3. 8 x 4 = 32, 10 x 4 = 40

4. 8 x 5 = 40

Both of those equations (in bold) have the same answer and he wanted the same crayons from both. So, the answer is:

10 x 4 = 40

8 x 5 = 40

(how much packs of each you need to get the same amount)

Hope this helps :)

Answer: 4:3 because 20 divided by 5 is 4 and 15 divided by 5 is 3.

Answer:

No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Step-by-step explanation:

Small number = S

Number = N

N = 2S + 3

N = 2(S+1)

N = N

2S + 3 = 2(S + 1)

2S + 3 = 2S + 2

-2S         -2S

3 = 2

No solutions

Therefore...

"No solutions exist because the situation describes two lines that have the same slope and different y-intercepts." is correct

Answer:

-120-x

Step-by-step explanation:

Given:

\(\displaystyle \large{|120+x| \quad (x < -120)}\)

This is the same as previous one. Recall modulus property:

\(\displaystyle \large{|a+x| = \begin{cases} a+x \quad (x \geq -a) \\ -a-x \quad (x < -a) \end{cases}}\)

Keep in mind that |x+a| and |a+x| are equal via addition property.

Since the question gives interval of x < -120:

Therefore, the expression is -120-x

Answer:

10.57 m

Step-by-step explanation:

Let the height of the parallelogram be x m

Area of the parallelogram = base*height

                                645    = (61 * x ) m

                                 x = 645/61

                                    = 10.57 m

Hope this helps

Height of parallelogram = 10.57m

Given,

Base of parallelogram = 61 m

Area of parallelogram = 645 m²

Now, according to formula

Area of parallelogram = Base × Height

Substitute the given values in the formula,

645 = 61 × height

Height = 10.57 m

Hence, the height of the parallelogram with area 645m² and base 61 m is 10.57 m  .

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

Triangle

The lateral face of a pyramid is a triangle, so a cross section that passes through the top vertex and the base is also a triangle.

Answer:

The output would depend on the input so relating this to the question, the input is the time (in minute) and the output is the amount of water left in the tank

We can give a letter 't' for the time, the input, and f(t) for the output

----------------------------------------------------------------------------------------------------------------

The original amount of water in the tank is 10450, so this will be the fixed constant.

The amount of water lost per minute is 270 so this will be the term that varies depends on the variable of time, we write this as 270t

The function is given f(t) = 10450 - 270t

--------------------------------------------------------------------------------------------------------------

Given, t = 10

f(10) = 10450 - 270(10)

f(10) = 7750 ml

Step-by-step explanation:

Answer:

 Part A:

Since the rate of 270 ml per minute has units of ml per minute, then yy must have units of ml and x must have units of minutes. The input must then be the number of minutes the tank is leaking for and the output is the number of ml of water remaining in the tank.

Part B:

Since the tank is leaking 270 ml per minute, then after x minutes, 270x ml of water has leaked out of the tank. The tank initially has 10,450 ml of water so after x minutes, there is y=10,450−270x ml remaining in the tank.

Part C:

After x=10 minutes, the amount of water remaining in the tank is y=10,450−270(10)=10,450−2,700=7,750 ml. There are 1,000 ml in 1 liter so 7,750 ml = 7.75 liters. There are then 7.75 liters of water left in the tank after 10 minutes.
