Step-by-step explanation:

AB and CD is not parallel because co-interior sum is 180 and another reason is that parallel sign isn't given.

Answer:

A = 160 in²

Step-by-step explanation:

Split this up into 3 rectangles and find the area of each (A = bh). Then add up all the areas to get the total area of the figure.

Rectangle A

A = 10 x 7

A = 70 in²

Rectangle B

A = 11 x 6

A = 66 in²
Rectangle C

A = 4 x 6

A = 24 in²

Total Area

A = 70 + 66 + 24

A = 160 in²

Hope this helps and God bless!

Answer:

160

Step-by-step explanation:

Do (6x4)+(6x18)+(7x4)

You don't need to put the parentheses but it makes it look better and make it easier to understand.

you can just split the figure in 2 separate figures and them add the areas:

area rec. 1:

3m×3m= 9m²

area rec. 2:

3m× (2m+3m)

= 3m×5m

=15m²

total area:

9m²+15m²= 24m²

Answer:

Area = 24

Answer: y= -1/20x + 38/5

or

y= -1/20x + 7.6

Step-by-step explanation:

y-y1 = m(x-x1)

m = 8-7 / -8 - 12 = 1/-20 = -1/20

y-8 = -1/20(x+8)

y=-1/20x - 8/20 + 160/20

y= -1/20x + 38/5

Answer:

16

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

Alright so:

-172 = -11x + 4

-4 - 4 (-4 on both sides)

so,

-176 = - 11x

divide by -11

so,

-11x ÷ - 11 = x

-176÷-11= 16

x=16

The rectangular prism with dimensions x units, 2x units, and x- 8 units has a surface area of 10x^2 - 48x square units

The formula for calculating the suface area of rectangular prism is expressed as:

A =2()

lw + wh + lh

where:

Given the following parameters

l = x units

w = 2x units

h = x -  8 units

Substitute

S = 2(2x^2 + x^2 - 8x + 2x^2 - 16x)

S = 2(5x^2-24x)

S= 10x^2 - 48x square units

Hence the rectangular prism with dimensions x units, 2x units, and x- 8 units has a surface area of 10x^2 - 48x square units

Answer:

(4,-1) is a solution

Step-by-step explanation:

x + 2y = 2

x - 2y = 6

We want to see if (4,-1) is a solution to the system.

To do so we plug in x = 4 and y = -1 into both equations and if it is true then the ordered pair is a solution but if one of the equations isn't true then the solution isn't a solution

x + 2y = 2

==> plug in x = 4 and y = -1

4 + 2(-1) = 2

==> multiply 2 and -1

4 - 2 = 2

==> subtract 2 from 4

2 = 2

x - 2y = 6

==> plug in x = 4 and y = -1

4 - 2(-1) = 6  

==> multiply -2 and -1

4 + 2 = 6

==> add 4 and 2

6 = 6

Both equations are true therefore (4,-1) is indeed a solution to the system

Answer:

Step-by-step explanation:

[tex]8( {7}^{x} ) = 2( {10}^{6} )[/tex]

[tex] {7}^{x} = 250000[/tex]

[tex]x = \frac{ ln(250000) }{ ln(7) } = 6.39[/tex]

The about 6 hours the bacteria population to reach 2 million.

An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable.

Given that the experiment requires the population of the bacteria to reach 2 million before the experiment can begin.

The reproduction rate of the bacteria can be modeled by the exponential equation,

y = 8 × 7ˣ.

So, according to the question,

8 × 7ˣ = 2 × 10⁶

7ˣ = 250000

x ≈ 6.4

Hence the about 6 hours the bacteria population to reach 2 million.

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish. So, Doug caught a fish that was 3/5 meters long.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways

Kim caught a fish that was 9/10 of a meter long. Doug caught a fish that was 2/3 as long as Kim's fish.

Kim caught a fish of length = 9/10 m

Doug caught a fish of length = 2/3 as long as Kim's fish.

                                                 = 2/3 x 9/10

                                                 = 18 / 30

                                                 = 3/5

To answer this, we substitute 12 ft to the f(h) in the given equation,   
f(h) = -8t² + 8t + 12 = 12

Subtracting 12 from both sides of the equation will give us an answer of,

-8t² + 8t = 0

Then, we transpose 8 to the other side and divide the equation by -8 and t, we get an answer of t = 1 second. 

Answer:

Below in bold.

Step-by-step explanation:

When he lands h = 0  so

-8t^2 + 8t + 12 = 0

Solving for t

t = [-8 +/- sqrt(8^2 - 3*-6*12)] / -16

t = 1.82 seconds.

Answer:

Option D, [tex]164\ units^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the front and back

[tex]A = l * w[/tex]

[tex]A = 10\ units * 4\ units[/tex]

[tex]A = 40\ units^2[/tex]

Step 2:  Determine the area of the sides

[tex]A = l * w[/tex]

[tex]A = 3\ units * 4\ units[/tex]

[tex]A = 12\ units^2[/tex]

Step 3:  Determine the area of the top and bottom

[tex]A = l * w[/tex]

[tex]A = 10\ units * 3\ units[/tex]

[tex]A = 30\ units^2[/tex]

Step 4:  Determine the total surface area

[tex]SA = 2(40\ units^2) + 2( 12\ units^2) + 2(30\ units^2)[/tex]

[tex]SA = 80\ units^2 + 24\ units^2 + 60\ units^2[/tex]
