Based on the graph given on the height of the helicopter, the slope and y-intercept of the function would be:

0 = Neither 5 = Neither 10 = Slope 50 = y-intercept 100 = Neither

How to find the slope and y-intercept?

To find the slope of the line om the height of the helicopter, the formula is:

= Change in y / Change in x

= (100 - 50) / (5 - 0)

= 50 / 5

= 10

The y-intercept takes the form b in the linear equation model:

y = mx + b

100 = 10(5) + b

b = 100 - 50

b = 50

The slope is 10 and the y-intercept is 50.

Based on the equation of the line that is parallel to the first line, the equation of the line in slope-intercept form is y = 3/4x - 6³/₄

How to write the equation?

First, find the slope of 3x + 4y = 7:
( 3x + 4y = 7) x 1/4

3/4x + y = 7/4

The slope is therefore 3/4x.

Lines that are parallel to each other have the same slope. You can therefore use this slope to find the formula of the other line by first solving for the y-intercept:
y = Slope(x) + y-intercept

-9 = 3/4(-3) + y-intercept

y-intercept = -6³/₄

⚠URGENT!!!⚠The larger prism has had two identical holes carved out of it, each of which is a rectangular prism. Find the volume of the remaining solid, writing your answer correct to 2 decimal places. Note that all measurements are in meters.

Volume=_____m^3

Answers

The volume of the remaining solid correct to 2 decimal places is 3634.60 m³

Calculating Volume

From the question, we are to determine the volume of the remaining solid

Volume of the remaining solid = Volume of the larger prism - Volume of the rectangular prisms carved out

First, we will determine the volume of the larger prism

Volume of the larger prism = 17 × 17 × 17

Volume of the larger prism = 4913 m³

Now, we will determine the volume of one of the rectangular prism that was carved out

Volume = 4 × 9.4 × 17

Volume = 639.2 m³

∴ Volume of the two identical holes carved out = 2 × 639.2 m³

= 1278.4 m³

Thus,

Volume of the remaining solid = 4913 m³ - 1278.4 m³

Volume of the remaining solid = 3634.60 m³

A pair of shoes usually sells for $68 if the shoes are 40% off and sales tax is 6% what is the total price of the shoes including tax

Answers

Usual selling price of a pair of shoes is $68 with discount 40% and sales tax 6% then total price of shoes including tax is equal to $43.248.

As given in the question,

Given that:

Usual selling price of shoes = $68

Discount on shoes =40%

Discounts an amount or percentage from something that they are selling, they take the amount or percentage off the usual price.

so, remove 40% from the price and you have left 60%

reduced price = 60% of $68

                         =60/100 * 68 = $40.8

Sales tax is 6% of reduced price= 6% of $40.8

                                           =$2.448 upto 3 decimal digits

Now , price including tax =$40.8+$2.448 =$43.248

Hence, total price including tax= $43.248

Therefore, usual selling price of a pair of shoes is $68 with discount 40% and sales tax 6% then total price of shoes including tax is equal to $43.248.

Change in temperature: (20 – (–16)) = 20 + 16 = 36

Answers

It will take the bottle of maple syrup 3 hours 45 minutes to reach  20° C from  –16° C.

How to get the temperature change

given data

the bottle temperature will go up a steady 9.6° C every hour

freezer temperature  = –16° C

final temperature = 20° C

The temperature rise from –16° C to 20° C

from –16° C to 0° C = 16° C

from 0° C to 20° C = 20° C

adding both increments gives = 20 + 16 = 36° C

if every hour we have 9.6° C then how many hours will give 36° C

1 hour = 9.6° C

? hour = 36° C

we cross multiply to have

= 36 * 1 / 9.6

= 3.75

This is 3 hours then a fraction of some minutes, the fraction is gotten by

What is area of rectangle?

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.

The area of a rectangle depends on its sides. Basically, the formula for area is equal to the product of length and breadth of the rectangle.

Let x be the width of the rectangle.

Length of the rectangle = x+8

Area of the rectangle = x(x+8)

According to question, new width= x+2

New length = x+2+8 = x+10

New area = (x+2)(x+10)

Area increased = (x+2)(x+10) – x(x+8)

x^2+12x+20-x^2-8x=68

Solve the simultaneous equations 4 x + 3 y = − 10 4 x + y = − 14

Answers

Answer:

x = - 4, y = 2

Step-by-step explanation:

First equation: 4x + 3y = - 10

Second equation: 4x+y= - 14

To solve simultaneously:

Rearrange one of the equations and substitute the equation to another equation, I prefer rearranging the second equation because it is easier.

Rearranging the second equation to get y, and then substitute back to the first equation to find x:

y = - 14 - 4x ------> new second equation

Substitute y (new second equation) into the first equation to find x:

4x +3(-14 -4x) = - 10

4x - 42 - 12 x = - 10

       - 8x - 42 = -10

                -8x = - 10 + 42

               - 8x = 32

                 8x = - 32

                   x = - 4

Now we substitute x = - 4 to the second equation to find y:

4x + y = - 14

y = - 14 - 4(-4)

y = - 14 - (-16)

y = - 14 + 16
