the sum of a number and twice a second number

Answer:

Total surface area = 340 cm²

Step-by-step explanation:

Surface area of the given prism = Area of two bases + Area of its lateral surfaces

Area of pentagonal base = [tex]\frac{1}{2}(\text{Apothem)}(\text{Perimeter})[/tex]

                                          = [tex]\frac{1}{2}(3.6)(5\times 5)[/tex]

                                          = 45 cm²

Area of the lateral sides of the prism = Perimeter of the pentagonal base × height

= (5×5)×10

= 250 cm²

Total surface area of the prism = 2(45) + 250

                                                     = 90 + 250

                                                     = 340 cm²

Answer:

n/12

Step-by-step explanation:

Answer:

A. 96

Step-by-step explanation:

By using slope formula we got that  average rate of change of the function over the interval [1, 3] is 48 .

the rate at which one variable of a function changes in relationship to another variable  is called average rate of change.

Here we can see in graph that

when x =1 y=12

and when x= 3 ,y=108

Now we know that rate of change is same as slope of straight line passing through that points

So average rate of change can be calculated as

[tex]=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]=\frac{108-12}{3-1}\\\\[/tex]

[tex]\frac{96}{2}[/tex]

=48

By using slope formula we got that  average rate of change of the function over the interval [1, 3] is 48 .

Step-by-step explanation:

y= -32/11+ A/11 - n/11

Answer:

Step-by-step explanation:

y =  -2x+1

rearrange to solve for x

2x = -y+1

x = -½y + ½

f⁻¹(x) = -½x + ½ = -(x-1)/2

Answer:

1/18

Step-by-step explanation:

Answer:

1/18

Step-by-step explanation:

1/3 / 6/1 =1/3 x 1/6 = 1/18

Solution :

Given :

X = homicide rate (homicides per 100,00 population)

n = 12 = metropolitan areas

Area                          X (homicides per 100,000 population)

Mesa, AZ                   4.1

Seattle, WA               3.8

Portland, OR (tie)      3.4

New York, NY(tie)     3.4

Virginia beach, VA   3.3

San Jose, CA           3.1

EI, Paso, TX             2.6

Austin, TX                2.6

San Diago, CA         2.4

Suffolk County         2.2

Montgomery, MD    2.0

Fairfax, VA              1.7

Therefore, the mean of X = [tex]$\bar X = \frac{\sum X_i}{n}$[/tex]

                                           [tex]$=\frac{34.9}{12}$[/tex]

                                          = 2.9

Therefore, the mean of homicide rater in the 12 metropolitan areas is 2.9 homicide per 100,000 population.

Answer:  y = 4x + 11

Step-by-step explanation:First, you put the equation into the standard “slope/intercept” form.

4x -y = 2 subtract 4x from both sides ; -y = -4x + 2 Multiply by -1 :

y = 4x - 2

In this standard form we see that the slope of the line (coefficient of x) is 4. ANY line parallel to this one must thus also have a slope of 4.

y = 4x - a (generic)

ANY other combination of slope multiples and constant terms will therefore also be lines parallel to this one. The one that passes through a specific point will simply have a different constant term.

We find this by putting our point value into the equation:

3 = 4(-2) + a ; 3 = -8 + a ; a = 11

Thus, our “parallel line equation” through the point (-2,3) is:

y = 4x + 11

Answer:

y = 3x + 12

Step-by-step explanation:

Slope (m) = 24-9/4-(-1)

= 25/5

= 3

Using point (-1 , 9)

y - y1 = m (x - x1)

y - 9 = 3 (x - -1)

y - 9 = 3 (x + 1)

y - 9 = 3x + 3

y = 3x + 3 + 9

y = 3x + 12

Answer:

the diameter would be 12.

Answer and Step-by-step explanation:

There aren't any real roots.

This is because the equation isn't factorable. You would have to use the quadratic formula to find the roots, which would be imaginary roots, and not real roots.

Answer:

equation: 3x - 20 = 0

Step-by-step explanation:

3x = 20

add its opposite to both sides.

3x - 20 = 20 - 20

= 3x - 20 = 0

Answer:

No. It is not safe.

Step-by-step explanation:

If the maximum safe incline for a ramp is said to be 8.5°, it means that the incline of any ramp that is greater than 8.5° is not safe.

Let's find the angle measure of the incline in the diagram given to ascertain whether it is safe or not.

Opposite side to angle of inclination = 20

Adjacent side to angle of inclination = 100

Apply the trigonometric function, TOA, which is:

Tan θ = Opp/Adjacent

Tan θ = 20/100

Tan θ = 0.2

θ = Tan^{-1}(0.2)

θ = 11.3099325° ≈ 11.3°

Angle of inclination for the ramp shown = 11.3°.

This is not safe because it has exceeded the maximum safe incline for a ramp which should be 8.5° maximum.

Let us set up a proportion.

4/3 = 18/t

Let t = height of giraffe (in inches)

We also have to change units to make our math work easier.

There are 12 inches in one foot.

So, 3 feet = 36 inches and 18 feet = 216 inches.

Our new proportion set up is:

4/t = 36/216

36t = 4(216)

36t = 864

t = 864/36

t = 24

The toy giraffe is 24 inches tall.

k=77

Step-by-step explanation:

put this as the equation k/11=7

what divided by 11 equals 7. Just multiply 11 and 7 to get the answer.

Answer:

Step-by-step explanation:

As we know, the four angles of the rectangle are 90°.

So, we need to find ∠AEB first.

∠AEB=180-44-90 (∠s sum of Δ)

= 46°

We can then work out x.

x=180-59-46 (adj. ∠s on st. line)

x=75°
