A fruit jucie company includes 1.231 ounce of apple jucie in 6.65- ounces bottel of a mixied fruit jucie. How much of the bottel of mixied fruit jucie is NOT apple jucie? THANK YOU!

Answers

Answer: 81.49% of bottle of mixed fruit juice is NOT apple juice.

Step-by-step explanation:

Quantity of mixed fruit juice  = 6.65 ounces

Quantity of apple juice in it = 1.231 ounce

Quantity of mixed fruit juice is NOT apple juice = (6.65-1.231) ounces

= 5.419 ounces

Fraction of bottle is not apple juice = [tex]\dfrac{5.419}{6.65}\approx0.8149=81.49\%[/tex]

Hence, 81.49% of bottle of mixed fruit juice is NOT apple juice.

The y- intercept has to be a point in the line where x is 0. Which means that in this case it would be -4.
To find the slope, use the formula: rise over run —> y2 - y1/x2 - x1

∠A is complementary to ∠B. The measure of ∠A is (8x+12)∘. The measure of ∠B is half the measure of ∠A.

Write an equation that can be used to determine the value of x. Then solve for x.

Answers

8x+12/2 is the answer

The equation that can be used to solve for x is 8x + 12 + 4x + 6 = 90.

The value of x is 6.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

∠A and ∠B are complementary.

This means,

∠A + ∠B = 90

Now,

∠A = 8x + 12

∠B = (8x + 12)/2 = 4x + 6

Now,

8x + 12 + 4x + 6 = 90

12x + 18 = 90

12x = 90 - 18

12x = 72

x = 72/12

x = 6

Thus,

The value of x is 6.

A store sells new video games for $25 each. Used video games sell for $10 each. Jacob is buying 3 new video games and x used video games. Which equation can be used to find y, the total price Jacob must pay in dollars?

Answers

Answer:

[tex]y = 75 + 10x[/tex]

Step-by-step explanation:

Given

New Video Games

[tex]Cost = \$25[/tex]

[tex]Number = 3[/tex]

Used Video Games

[tex]Cost = \$10[/tex]

[tex]Number = x[/tex]

Required

Determine the amount spent (y)

First, we need to determine the total spent on new games

1 new game = $25

3 new games will be: 3 * $25

Next, we determine the total spent on old games

1 used game = $10

x used games will be: x * $10

So, total amount y, is:

[tex]y = 3 * 25 + x * 10[/tex]

[tex]y = 75 + 10x[/tex]

a suitcase measures 24 inches long and 18 inches high, what is the diagonal length of the suitcase?

Answers

Answer:

The diagonal is 30 inches

Step-by-step explanation:

Assuming a rectangular suitcase (with right angles), we can use the Pythagorean theorem to solve this

a² + b² = c²

so we plug our two values to find the diagonal (hypotenuse)

24² + 18² = c²

576 + 324 = c²

900 = c²

c = √900

c = 30

The diagonal is 30 inches

Answer:

the diagonal is 30 inches

Step-by-step explanation:

you assume a suitcase is a rectangular shape, and the diagonal length makes 2 right triangles; therefore you can use Pythagorean theorem

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex] ; where a = 24, b = 18 and c is the diagonal

[tex]24^{2}[/tex] + [tex]18^{2}[/tex] = [tex]c^{2}[/tex]

[tex]c^{2}[/tex] = 576 + 324

[tex]c^{2}[/tex] = 900

c = 30 inches
