Answer:

[tex]200 cm^2[/tex]

Step-by-step explanation:

A = (1/2)bh

A = (1/2)(18)(30)

A = 270 square cm

A = (1/2)(16)(25)

A = 200 square cm

Answer:

200 square centimeters

Step-by-step explanation:

The area of a triangle can be calculated using the formula: [tex]A = \frac{1}{2}bh[/tex] where b is the base and h is the height. So if the base is 16 cm and the height if 25 cm you simply plug the values into the equation to find the area

Plug Values In:

[tex]A = \frac{1}{2}(16 cm)(25 cm)[/tex]

Multiply 16 cm and 25 cm:

[tex]A = \frac{1}{2}(400 cm^2)[/tex]

Multiply by 0.5 (or technically divide by 2)

[tex]A = 200 cm^2[/tex]

Answer: -2 1/3

Answer:

Step-by-step explanation:

Area of a scaled figure is multiplied by the square of the scale factor; volume is multiplied by the cube of the scale factor.

When dimensions are multiplied by 3, the area is multiplied by 3² = 9.

Area of the larger figure is 9 times that of the smaller one.

When dimensions are multiplied by 3, the volume is multiplied by 3³ = 27.

Volume of the larger figure is 27 times that of the smaller one.

__

Additional comment

In general, the area of a figure is the sum of the products of two orthogonal dimensions. If each of those is multiplied by 3, then the product is multiplied by 3 twice, or 3² = 9.

Similarly, the volume of a figure is the sum of products of three orthogonal dimensions. When those are each multiplied by 3, the product is multiplied by 3 three times, or 3³ = 27.

Using the linear function given in this problem, the formula underestimates the median weekly earnings in 2013 by $3, as 657 < 660.

The function that estimates the median weekly earnings n years after 1980 is:

W = 13n + 231.

2013 is 2013-1980 = 33 years after 2000, hence the estimate is given by W when n = 33, that is:

W = 13 x 33 + 231 = 660.

657 < 660, hence the formula underestimates the median weekly earnings in 2013 by $3.

Answer:

t = 1.322

Step-by-step explanation:

4×(2^t) = 10

2^t = 10/4 = 2.5

t = log2(2.5)

now, the logarithm to the base 2 of 2.5 must be larger than 1, as 2.5 is larger than 2.

so, it can be only the 4th answer option.

now, to actually calculate it :

log2(2.5) = log10(2.5) / log10(2) = 1.321928095... ≈

≈ 1.322

we were correct.

Answer:

t = 1.322

Step-by-step explanation:

Given equation:

[tex]4(2^t)=10[/tex]

Divide both sides by 4:

[tex]\implies \dfrac{4(2^t)}{4}=\dfrac{10}{4}[/tex]

[tex]\implies 2^t=2.5[/tex]

Take natural logs of both sides:

[tex]\implies \ln 2^t = \ln 2.5[/tex]

[tex]\textsf{Apply the natural log power law}: \quad \ln x^n=n \ln x[/tex]

[tex]\implies t \ln 2 = \ln 2.5[/tex]

Divide both sides by ln 2:

[tex]\implies \dfrac{t \ln 2}{\ln 2} = \dfrac{\ln 2.5}{\ln 2}[/tex]

[tex]\implies t= \dfrac{\ln 2.5}{\ln 2}[/tex]

[tex]\implies t=1.321928095...[/tex]

[tex]\textsf{Apply log law}: \quad a^c=b \iff \log_ab=c[/tex]

[tex]\implies \log 2 (2.5)=t[/tex]

[tex]\implies t=1.321928095...[/tex]

Therefore, the solution that is nearest to the exact solution is t = 1.322

The number of miles the bird can fly for 60 minutes is 20 miles.

A bird can fly 5 miles in 15 minutes.

Let's find the rate before we can find the number of miles the bird can fly in 60 minutes.

Therefore,

rate = distance / time

rate = 5 / 15  = 1 / 3 miles per minutes

Therefore,

1 / 3  = d / 60

cross multiply

60 = 3d

d = 60 / 3

d = 20 miles

if you are asking a real question the answer should be on your driving history on life 360 or maybe the average gps. How fast were you driving? I have no idea thats a answer only you know.

Step-by-step explanation:

Answer:

r = 70.59  miles / hour

Step-by-step explanation:

Comment

The first set of numbers gives you the distance you travelled.

Givens

t = 20 minutes = 20/60 = 1/3 of an hour

r = 60 miles / hour

d = ?

d =  r * t

d = 60 * 1/3

d = 20 miles  (The hours cancel)

So now you can find out what 17  minutes means

d = 20 miles

t = 17 minutes = 17/60 hours = 0.2833 hours.

r = d / t

r = 20 / 0.2833

r = 70.59  miles / hour

A heat engine is a device that turns heat into mechanical energy that may subsequently be utilized to do mechanical labour. The total rate of heat rejection to the environment is 298.4458 kJ/min.

A heat engine is a device that turns heat into mechanical energy that may subsequently be utilized to do mechanical labour. It accomplishes this by transferring a functioning ingredient from a higher to a lower state temperature.

For the following condition, the diagram can be made as shown below. Also, the Heat Engine Sink temperature, [tex]T_H[/tex] = 900 K

Heat Engine surrounding temperature, [tex]T_L[/tex] = 300 K

Refrigerator surrounding temperature, [tex]T'_C[/tex] = 215 C + 273 =  488 K

Refrigerator sink temperature, [tex]T'_H[/tex] = 300 K

The heat removed by the refrigerator, [tex]Q'_{in}[/tex] = 250 kJ/min

A.) For a Carnot refrigerator, the COP or the coefficient of performance is given by,

[tex]COP = \dfrac{T'_C}{T'_H-T'C}[/tex]

COP = (488)/(488-300)

COP = 2.596

The COP is also the ratio of the Heat input and the work output.

[tex]COP = \dfrac{Q'_{in}}{W}[/tex]

2.596 = 250/W

W = 96.302 kJ/min

The Carnot engine efficiency is expressed as,

[tex]\eta = 1- \dfrac{T_C}{T_H}[/tex]

η = 1 - (300/900)

η = 0.6667

Also, the Carnot engine efficiency is defined as,

[tex]\eta = \dfrac{W}{Q_{in}}\\\\[/tex]

[tex]0.6667 = \dfrac{96.302}{Q_{in}}\\\\Q_{in} = \rm 144.4458\ kJ/min[/tex]

Hence, the rate of heat supplied to the heat engine is 144.4458 kJ/min.

B.) The total work done by the engine is 96.302 kJ/min, while the heat input is 144.4458 kJ/min. Therefore, the heat output of the system is,

[tex]W = Q_{in} - Q_{out}\\\\Q_{out} = 48.1438\rm\ kJ/min[/tex]

Thus, the total rate of heat rejection to the environment,

[tex]\text{Total Heat rejection} = Q_{out}+Q'_{in}\\[/tex]

                               = 48.4458 kJ/min + 250 kJ/min

                                = 298.4458 kJ/min

Hence, the total rate of heat rejection to the environment is 298.4458 kJ/min.

Step-by-step explanation:

Hello!

Slope - Intercept Form: [tex]y = mx+b[/tex]

The slope of the line is the rate of change, or how the graph changes in y as it changes in x.

Slope can be calculated by the formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

We need two points on the line to get the x and y-values. I'm going to choose points (0,5) and (4,-3).

Calculate Slope

The slope is -2.

The y-intercept of the line is where the graph touches the y-axis (x = 0). It can be found by looking at the intersection of the graph and the axis.

The intersection happens at point (0,5), so the y-intercept is 5.

We found m, the slope, to be -2 and b, the y-intercept, to be 5. We can just plug it into the equation format.

Equation: [tex]y = -2x + 5[/tex]

The y-intercept is the the point where the graph crosses the y-axis. The value of x is zero there. The coordinates of the y-intercept are (0, 8).

The x-intercept is the point where the graph crosses the x-axis. The value of y is zero there. The coordinates of the x-intercept are (9, 0).
