 situation 1: kayla has $30 to spend on yogurt. She spent a total of $6 each day on yogurt.
in situation 1, which role model is the total amount that Kayla has left to spend on yogurt (c) as a function of the numbers of days (d)
A) c=30-6d
B) c=30+6d
C) d=30-6c
D) c=6d-30

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Kayla spends 6 a day and has a total of 30 dollars, c is the amount left over so this would make the equation c=30-6d

Answer 2

The correct statement will be;

⇒ c = 30 - 6d

Where, 'c' is left amount and 'd' is number of days.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Kayla has $30 to spend on yogurt.

And, She spent a total of $6 each day on yogurt.

Now,

Let 'c' is left amount and 'd' is number of days.

And, She spent a total of $6 each day on yogurt.

So, We can formulate;

⇒ c = 30 - 6d

Where, 'c' is left amount and 'd' is number of days.

Thus, The correct statement will be;

⇒ c = 30 - 6d

Where, 'c' is left amount and 'd' is number of days.

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

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.
