For area, just multiply the length x width
So therefore, multiply 36 inches x 48 inches and there you have it.

Now for the perimeter, it is a little different
You'd have to add the sides up together to get your answer for the perimeter.
So, 36 in + 36 in + 48 in + 48 in = answer

Answer: Perimeter = 168 inch

             Area = 1728 inch²

Step-by-step explanation:  Length(L)=36 inch ,Breath(B)=48 inch

Perimeter of rectangle =2(L+B)

                                        =2(36+48)

                                        =168 inch

Area of rectangle =L× B

                               =36 × 48

                               =1728 inch²

6) slope is 1, y-intercept is 3, equation in slope-intercept form:

y=x+3

7) Slope of the line that goes through the points (3,9) and (-5,3) is Slope=\frac{3}{4}

8) Slope = m= \frac{2}{3}

y-intercept = b= -4

Step-by-step explanation:

6) Create table of coordinate points:

x     y

-2    1

-1     2

0     3

1      4

2     5

Identify the slope:

Using formula:

Slope=\frac{y_2-y_1}{x_2-x_1}

Putting values:

Slope=\frac{2-1}{-1-(-2)}

Slope=\frac{1}{-1+2}

Slope=\frac{1}{1}

Slope=1

So, slope is 1

Identify y-intercept.

y-intercept is found when x=0, so, looking at the table when x = 0, y= 3 so, y-intercept is 3

Equation in the form: y=mx+b

here m is slope and b is y-intercept

Putting values:

y=mx+b\\y=1x+3\\or\,\,y=x+3

So, equation in slope-intercept form:

y=x+3

7) Find the slope of the line that goes through the points (3,9) and (-5,3)

Using formula:

Slope=\frac{y_2-y_1}{x_2-x_1}

Putting values:

Slope=\frac{3-9}{-5-(3)}

Slope=\frac{-6}{-5-3}

Slope=\frac{-6}{-8}

Slope=\frac{3}{4}

So, slope of the line that goes through the points (3,9) and (-5,3) is Slope=\frac{3}{4}

8) What is the slope and y-intercept of the following equation:

y=\frac{2}{3}x-4

The equation is in slope-intercept form

The general equation of slope-intercept form is:

y=mx+b

where m is slope and b is y-intercept

Comparing both equations we get:

Slope = m= \frac{2}{3}

y-intercept = b= -4

The diameter of a human red blood cell is 0.000009 m. The diameter of a cold virus is 0.00000003 m Approximately how many times
krek1111 [17]

Answer:

D. 3*10^2

Step-by-step explanation:

Given the diameter of human red blood cell =  0.000009 m

diameter of a cold virus = 0.00000003 m

To know how many times as large is the diameter of a red blood cell as the diameter of a cold virus, we will take the ratio of the diameter of human red blood cell to that of a cold virus as shown;

diameter of human red blood cell/diameter of a cold virus = 0.000009 m/0.00000003 m

= 9*10^-6/3*10^-8

= 9/3 * 10^-6-(-8)

= 3 * 10^(-6+8)

= 3*10^2

Hence the diameter of a red blood cell is 3*10^2 larger than that of the cold virus

Use elimination to solve each system.
Cerrena [4.2K]

Answer:

$3 and $2

Step-by-step explanation:

let p represent popcorn and d drinks , then

2p + 3d = 12 → (1)

3p + 5d = 19 → (2)

multiplying (1) by 3 and (2) by - 2 and adding will eliminate p

6p + 9d = 36 → (3)

- 6p - 10d = - 38 → (4)

add (3) and (4) term by term to eliminate p

0 - d = - 2

- d = - 2 ( multiply both sides by - 1 )

d = 2

substitute d = 2 into either of the 2 equations and solve for p

substituting into (1)

2p + 3(2) = 12

2p + 6 = 12 ( subtract 6 from both sides )

2p = 6 ( divide both sides by 2 )

p = 3

Popcorn costs $3 and a drink costs $2

In the diagram shown,
stich3 [128]

Answer:

1/2 * (5+3) * 6 = 24 cm^2

Step-by-step explanation:

Perimeter is 20

and it's a rectangle so 2x + 12= 20

x is 4 so one of parallel side of trapezium is 9-4 or 5 then just apply formula for area of trapezium
