A airplane can hold 62 gallons of diesel.For each kilogram traveled, the airplane used 1/15 of kilograms of diesel. How far can the airplane go before it runs out of diesel?
Answers
The distance the airplane can travel before it runs out of diesel is 15.67.
What is the distance the plane can travel?The first step is to convert gallon to kilogram
1 gallon = 3.79 kg
62 x 3.79 = 234.98 kg

the scale factor of the larger of two similar rectangular prisms is 1/8. the surface area of the larger prism is 740 ft2. identify the surface area, rounded to the nearest tenth, of the smaller prism
Answers
Answer:
11.6 ft²
Step-by-step explanation:
We assume the 1/8 scale factor is the ratio of the linear dimensions of the smaller of the prisms to the larger. The ratio of areas will be the square of the ratio of the linear dimensions.
__
The ratio of areas will be ...
smaller area / larger area = (scale factor)²
smaller area = (larger area)×(scale factor)² . . . multiply by the denominator
smaller area = (740 ft²) × (1/8)² = 11.5625 ft² . . . use given values
The surface area of the smaller prism is about 11.6 square feet.
Grayson measured a line to be 10.9 inches long. If the actual length of the line is 13.4 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answers
The percent error of the measurement, to the nearest tenth of a percent is 18.6%
Calculating percent errorThe formula for calculating the percent error is expressed as:
%error = actual - measure/actual * 100
Given the following
actual length = 13.4 in
Measured =10.9in
Substitute
%error = 13.4-10.9/13.4 * 100
%error = 2.5/13.4 * 100
%error = 18.65%
Hence the percent error of the measurement, to the nearest tenth of a percent is 18.6%

Answer:
26 degrees.
Step-by-step explanation:
The angles of triangles will always add up to 180 degrees.
The first angle is 50 degrees.
The second angle, is shown with a 76 degree angle next to it.
Since this is a 180 degree line, we can find the angle of the bottom right corner by doing 180 - 76. 180 - 76 is 104.
104 + 50 = 154 degrees.

Answer:
x^2-12x+36
Step-by-step explanation:
The first step in solving this equation is to expand the square which makes the equation (x-6)(x-6). Then you distribute the x to both parentheses which leaves you with x^2-6x, and then you distribute the 6 to both parentheses which gives you 6x+36. Then add both binomials which leaves you with x^2-12x+36. The reason it is +36 and not -36 is because you are multiplying a negative 6 by another negative 6.

You will need to look up the formula for surface area of a sphere.
Answers
For problem 17, if you double the diameter of the moon, then the surface increases by a factor of 4 and the volume by a factor of 8.
How to compare the change in surface and volume?
Let's answer question 17.
Remember that for a sphere of radius R, the volume is:
[tex]V = (4/3)*pi*R^3[/tex]
And the surface area is:
[tex]S = 4*pi*R^2[/tex]
So the volume depends on the cube of the radius and the surface on the square of the radius.
Now, if we double the diameter of the moon, then we also double the radius.
So the new volume will be:
[tex]V' = (4/3)*pi*(2*R)^3 = 8*[(4/3)*pi*R^3] = 8*V[/tex]
The new volume is 8 times the original volume.
And for the surface:
[tex]S' = 4*pi*(2*R)^2 = 4*[4*pi*R^2] = 4*S[/tex]
So the new surface is 4 times the original surface.

You flip a fair coin 25 times in the air. what is the relative frequency with which the coin will land on tails 12 of those times?
Answers
For the given experiment, the relative frequency of getting tails is:
R = (12/25)*100% =48%
How to get the relative frequency?
If we perform an experiment N times, and out of these N times, K times we get a given outcome (Where K is a number equal to or smaller than N).
The relative frequency of that particular outcome is given by the quotient between the number of times that we got that outcome and the total number of times that the experiment was performed.
In this case, the experiment is performed 25 times, and 12 times we get tails, then the relative frequency for getting tails is:
R = 12/25
