Answer:

12.57 in^3

Step-by-step explanation:

The easiest way to do this is to find the area of the circle surface and multiply it by the height

to find area the formula is pi r^2 and we are given the radius

so we plug in pi(2^2)=pi(4)= roughly 12.57

then we multiply the area by the height which is 1 so it would be the same

12.57(1)=12.57

Answer:

( -9, -6)

Step-by-step explanation:

The red dot is the original (6, 9)

The blue dot is when it is rotated 270 degrees clockwise (-9, -6).

Answer:

The home is worth $424,528 today

Step-by-step explanation:

To get the worth of the home today, we are going to use the exponential formula

We have this as follows;

A = P(1 + r)^t

where A is the value of the house after some time t

P is the initial value the home was worth which is $160,000

r is the rate of increase in the price of the home which is 5% = 5/100 = 0.05

t is the number of years which is 20

substituting these values;

A = 160,000(1 + 0.05)^20

A = $424,528

The rate of change is just miles per hour.

Answer/ Step-by-step explanation:

12>6(12x+2)

Divide both sides by 6. Since 6 is positive, the inequality direction remains the same.

12/6 >12x+2

Divide 12 by 6 to get 2.

2>12x+2

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

12x+2<2

Subtract 2 from both sides.

12x<2−2

Subtract 2 from 2 to get 0.

12x<0

Product of two numbers is <0 if one is >0 and the other is <0. Since 12>0, x must be <0.

x<0

Answer:

80+2x=180°{co-interior angle}

2x=180-80

2x=100

x=50°

hope it helps.

Answer:

2x + 10

Step-by-step explanation:                                                                                      2 * (x + 5)                                                                                                                   = 2x + 10

Answer: 4950 cubic centimeters.

Step-by-step explanation:

We know that, the volume of box = Base area x height

Given: area of the base of a box  = 825 sq. centimeters

height = 6 centimeters.

Then, Volume of the box in cubic centimeters = 825 x 6

= 4950 cubic centimeters.

hence, the volume of the box in cubic centimeters = 4950 cubic centimeters.

Answer:

10218.75

Step-by-step explanation:

You should divide the two shapes into a rectangle and a triangle, find the area of each, then add them together like so:

For the rectangle:

37.5*22.5 = 843.75

For the triangle:

To find the base: 75 - 37.5 = 37.5

To find the height, use pythagoream theorem.

62.5² = 37.5² + b²

3906.25 = 1406.25 + b²

3906.25 - 1406.25 = 2500

√2500 = 50.

The height is 50, so 50*37.5(1/2)

= 937.5

Now add them together

937.5 + 843.75

Answer:

Step-by-step explanation:

Imagine or draw a triangle with horizontal leg length 8 - (-4), or 12, and vertical leg length |-6 - 2|, or 8.  Use the Pythagorean Theorem to find the length of the hypotenuse:  

length of hypotenuse = +√(8² + 12²) = √208 = 4√13  (Answer A)

Answer:

z = 137 degrees

Step-by-step explanation:

Angle 43 and angle z make a straight line, which is 180 degrees

43+z = 180

Subtract 43 from each side

43+z-43 = 180-43

z =137

Answer:

1/9

Step-by-step explanation:

Probability  =  Expected outcome/Total outcome

From the given pi chart,

Total outcome = 360degrees (since the total angle in a circle is 360 degrees)

Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;

Expected outcome = 40degrees

Pr(scoring a 5) = 40/360

Pr(scoring a 5) = 1/9

Hence the probability of scoring a 5 is 1/9

Answer:

1/9

Step-by-step explanation:

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Divide the number of events by the number of possible outcomes.

Answer:

320

Step-by-step explanation:

I attached my work, for coming questions that is the formula

10 = base length

8 = base width

12 = pyramid height

Answer:

V = 320ft³

Step-by-step explanation:

Given

L = 10 W = 8 H = 12

Solution

V = LWH/  3= 10·8·12/ 3 = 320

Therefore, the volume of the given pyramid is V = 320ft³

a straight line = 180 so 1+2 has to = 180 1+3 has to = 180 2+4 has to = 180 and so on

Answer:

x = 80

Step-by-step explanation:

Sum of all the angles of triangle = 180

30 + 70 + x = 180

       100 + x = 180        {Subtract 100 from both sides}

                x =  180 - 100

                x = 80°

Answer:

-18 C°

Step-by-step explanation:

Warmed means add cooled means subtract

starting at -23 it warmed by 8 add 8

-15

it warmed by 3 more add 3

-12

then it cooled by 6 subtract 6

-18
