Answer:
2162 miles
Step-by-step explanation:
The equation of the circumference of a circle is d*pi = Circumference. Knowing this, We can do a one step equation and divide be pi on both sides to find the diameter. All you have to do is plug the numbers in and divide 6790 by 3.14 to find 2162. (Rounded to the nearest mile)
Final answer:
To find the diameter of the moon, use the formula for circumference. Given the circumference of the moon, substitute the value into the formula to find the radius. Multiply the radius by 2 to find the diameter. Round the result to the nearest mile.
Explanation:
To find the diameter of the moon, we can use the formula for circumference: Circumference = 2πr, where r is the radius. Given that the circumference of the moon is about 6,790 miles, we can rearrange the formula to solve for the diameter. Since diameter is twice the radius, we have Diameter = 2r. Substitute the given circumference value into the formula to find the radius. Then multiply the radius by 2 to find the diameter. Round the result to the nearest mile.
Step 1: Circumference = 2πr
Step 2: Given circumference = 6,790 miles
Step 3: Solve for r: 6,790 miles = 2πr
Step 4: Divide both sides of the equation by 2π: r ≈ 1,080 miles
Step 5: Multiply r by 2 to find the diameter: Diameter ≈ 2 * 1,080 miles ≈ 2,160 miles
Therefore, the diameter of the moon, rounded to the nearest mile, is approximately 2,160 miles.

Step-by-step explanation:
Twenty gremlins and fifteen imps are at the Annual Mischief Convention. The imps have had a lot of in-fighting lately and refuse to shake hands with each other, but they readily shake hands with all of the gremlins. Meanwhile, all the gremlins are quite friendly and shake hands with all of the other gremlins as well as imps. Each pair of creatures shakes hands at most once. How many handshakes were at the convention?
Answer:
490
Step-by-step explanation:
Let us first count the handshakes between two gremlins. There are 20 gremlins, so there must be 20*19/2=190 handshakes between two gremlins, making sure to divide by two to avoid over-counting.
There are 15 imps that shake hands with each of the 20 gremlins, which makes 15* 20 = 300 handshakes between imps and gremlins.
Adding these up, you have $300 + 190 = 490 total handshakes.
Hope this helps!
The sum of the 8th element and the 12th element of an arithmetic progression
is 246. The sum of the 10th and the 14th element is 298. What is the value of
the 35th term?
Answer:
448
Step-by-step explanation:
aₙ = a₁ + (n-1)d
a₈ = a₁ + (8-1)d = a₁ + 7d
a₁₂ = a₁ + 11d
a₈ + a₁₂ = 246 = 2a₁ + 18d a₁ + 9d = 123
a₁₀ + a₁₄ = a₁ + 9d + a₁ + 13d = 298 a₁ + 11d = 149
2d = 26
d = 13
a₁ = 6
a₃₅ = 6 + (35-1) x 13 = 448

What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
If the area he paces divided by the area his apprentice paces equals three, then we can write it as;
J/a = 3
In ratio form,
J : a = 3 : 1
Where J. represent Harry and. a represent the apprentice. Hence,
Therefore, the area Harry will pace;
= ( 3/4) × 140 ft.²
= 105 ft.²

Find the slope of the line through the points (4, -1) and (-2, -1).
To find the slope (m), use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] And plug in the two points
(-2, -1) = (x₁, y₁)
(4, -1) = (x₂, y₂)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-1-(-1)}{4-(-2)}[/tex] (two negative signs cancel each other out and become positive)
[tex]m=\frac{-1+1}{4+2}[/tex]
[tex]m=\frac{0}{2}[/tex]
m = 0
Answer:
The slope is 0.
Step-by-step explanation:
Write an equation of the line that passes through the points (0,4) and (2,10).
Answer:
First you find the slope:
(10-4)/2 = 6/2 = 3
Then you write a point-slope equation:
y-4=3x
in slope-intercept form:
y=3x+4
Answer:
The equation of the line is y = 3x + 4.
Step-by-step explanation:
First find the slope of the line:
Slope (m) = rise / run
= difference in y coordinates / difference in corresponding x coordinates
= (10-4) / (2 - 0)
= 6/2
= 3..
The line is written as
y = m x + b
We have just found m (= 3). Now we find the value of b by substituting the point (0, 4) into this equation.
4 = 3(0) + b
b = 4.
So the required equation is y = 3x + 4.

2.0% of the mass of a 150g apple is sugar.
How much sugar is contained in I apple
The apple, weighing 150g, contains 2.0% sugar by mass. Calculating this percentage, we find out that the apple contains 3.0g of sugar.
Explanation:To find out how much sugar is contained in a 150g apple, where 2.0% of its mass is sugar, we use simple percentage calculations. We know that 1% of 150g is 1.5g (150/100), so 2.0% of 150g would be 2 times 1.5g, which comes to 3.0g. Thus, the apple contains 3.0g of sugar.

A spinner has 10 equal-sized sections. Two of the sections are red.
a. What is the probability that the spinner will land on red?
b. Use words to describe the probability.
Answer:
a. Probability of landing on red = [tex]\frac{1}{5}[/tex]
b. See Explanation
Step-by-step explanation:
Given
A Spinner
Number of section = 10 (equal sized)
Number of red section = 2
Required
- Probability of landing on red
- Describe the probability in words
Calculating the probability of landing on red
The formula used in calculating probability is as follows
Probability = Number of required outcomes / Number of possible outcomes
In this case, the number of required outcomes is the number of red section.
Hence, number of required outcomes = 2
And the number of possible outcomes is the total section of the spinner
Hence, Number of possible outcomes = 10
By Substitution
Probability of landing on red = [tex]\frac{2}{10}[/tex]
Probability of landing on red = [tex]\frac{1}{5}[/tex]
Describe the probability in words
From (a) above, we have that the probability of the spinner landing on color red is [tex]\frac{1}{5}[/tex]
This means that, for every five times, you spin the spinner, it's likely that one of the outcomes will be red.
