Answer:

1 inch= 4 feet for both

Step-by-step explanation:

This also means that the scale converts to 1/4 in. = 12 in.

stay safe

Using proportions, it is found that the scale is of 0.25 inches per feet.

The rule of three is:

3 inches - 12 feet

x inches - 1 feet

Applying cross multiplication:

[tex]12x = 3[/tex]

[tex]x = \frac{3}{12}[/tex]

[tex]x = \frac{1}{4}[/tex]

[tex]x = 0.25[/tex]

The scale is of 0.25 inches per feet.

Answer: -4t + 1590

Step-by-step explanation:

Given : Josh works as a tutor for $11 an hour and as a waiter for $15 an hour.

This month, he worked a combined total of 106 hours at his two jobs.

Let t be the number of hours Josh worked as a tutor this month.

Then, the number of hours Josh worked as a waiter = 106 -t

Then, the total money earned this month ( in dollars)

= 11 (No. of hours worked as a tutor)+ 15 (No. of hours worked as a waiter)

=11(t) + 15(106-t)

= 11t+1590-15t

= -4t+1590

Hence, the expression for the combined total dollar amount he earned this month =

The algebraic expression to this problem is 11x + 15y = 106

Algebraic expressions have variables, numbers, and operations. A variable is a letter that represents an unknown amount.

Let number of hours Josh worked as a tutor be x hour.

Let number of hours Josh worked as a waiter be y hours.

Answer:

11 nights

Step-by-step explanation:

Our total budget: $137

First, let's deduct the cost to enter the park.

137 - 5 = 132

We have $132 to spend on the hotel.

Since the cost is $12 per night, we need to find out how many times $12 can go into $132. This is done using division.

132 / 12 = 11

As we can see, we can pay $12 eleven times until our money runs out.

Thus, we can stay at the camp for 11 nights!

5x - (2x - 1) = 2

Distribute the - sign.

5x - 2x + 1 = 2

Combine like terms.

3x + 1 = 2

Subtract 1 from both sides.

3x = 1

Divide both sides by 3

x = 1/3 or 0.33

Step-by-step explanation:

From the image attached, the length of the bouncy castle is X² +4 and the width is 2x² - 3x  +7

The bouncy castle is a rectangle. A rectangle is a quadrilateral in which opposite sides are equal and all the angles have equal measures. The diagonals of a rectangle also bisect each other. The perimeter of a rectangle = 2(length + breadth), Hence for the bouncy castle:

Perimeter of castle = 2(length + breadth) = 2(x² + 4 + (2x² - 3x  +7)) = 2(3x² - 3x + 11) = 6x² - 6x + 22

Perimeter of castle = 6x² - 6x + 22

The area of the castle = length × breadth = x² + 4 × (2x² - 3x  +7)) = 2x⁴ - 3x³ + 7x² + 8x² - 12x + 28 = 2x⁴ - 3x³ + 15x² - 12x + 28

3x + -1 = 9

3x = 10

x = 10/3

Using it's concept, it is found that the probability that the golf ball is green or red is of 0.55.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, there are 6 + 5 + 9 = 20 balls, of which 11 are green or red, hence the probability is given by:

p = 11/20 = 0.55.
