The circumference of the moon is about 6,790 miles Find the diameter of the moon to the nearest mile. help somebody
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.
What is 2(2x + 1) = x + 5?
Answer:
1
Step-by-step explanation:
2(2x+1)=x+5
4x+2=x+5
3x=3
x=1
Answer:
x=1
Step-by-step explanation:
2(2x + 1) = x + 5
Distribute
4x +2 = x+5
subtract 4 from each side
4x-x +2 = x-x+5
3x +2 = 5
Subtract 2 from each side
3x+2-2 = 5-2
3x = 3
Divide by 3
3x/3 = 3/3
x=1

will mark brainiest: What is the area of a circle with a radius of 7 cm? (Use 3.14 for Pi and round to the nearest tenth.)
38.5 centimeters squared
44.0 centimeters squared
150.0 centimeters squared
153.9 centimeters squared
The area of a circle is πr². We know r is 7, so the area is π * 7² = 49π.
Substituting, we have 49 * 3.14 = 153.86, which rounds to 153.9 centimeters squared.
The area of circle with a radius of 7 cm is,
⇒ 153.9 centimeters squared
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
Radius of circle = 7 cm
Now, We know that;
Area of circle is,
A = πr²
Where, 'r' is radius of circle.
Here, Radius of circle = 7 cm
Hence, The area of circle with a radius of 7 cm is,
⇒ A = πr²
⇒ A = 3.14 × 7²
⇒ A = 3.14 × 49
⇒ A = 153.9 centimeters squared
Thus, The area of circle with a radius of 7 cm is,
⇒ 153.9 centimeters squared

A scientist calculated the mean and standard deviation of a data set to be Mu = 120 and Sigma = 9. She then found that she was missing one data value from the set. She knows that the missing data value was exactly 3 standard deviations away from the mean. What was the missing data value?
Answer:
The missing data value is 147
Step-by-step explanation:
The mean is 120
The standard deviation is 9
Missing data value = ?
From the question, the missing data value is 3 standard deviation away from the mean.
3 standard deviation = 3 * 9 = 27
3 standard deviation from the mean = 120 + 27 = 147
The missing data value is what we get after adding 3 standard deviation from the mean.

you have $15.
a. How much money do you have left if you ride each ride once?
You have $
left.
b. Do you have enough money to ride each ride twice? Explain.
It costs $
to ride each ride once, and you have $
left.
Question 2
response - correct
To find out how much money you have left after riding each ride once, subtract the total cost of all the rides from the amount of money you have. To find out if you have enough money to ride each ride twice, multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have.
Explanation:a. To determine how much money you have left if you ride each ride once, you need to know the cost of each ride. Let's say each ride costs $3. To find out how much money you have left, you subtract the total cost of all the rides ($3 x number of rides) from the amount of money you have. So, in this case, you have $15 - ($3 x number of rides) left.
b. To determine if you have enough money to ride each ride twice, you multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have. So, if each ride costs $3, you would calculate $3 x 2 = $6 to see if it is less than or equal to $15.
Property of Circles: Segment Relationships in Circles
Answer:
x = 5
Step-by-step explanation:
Two secants from an external point to a circle, then the product of one secant's external part and the entire secant is equal to the product of the external part and the entire secant of the other, that is
(x - 2)(x - 2 + x + 4) = 4(4 + 5)
(x - 2)(2x + 2) = 4(9) = 36 ← distribute and simplify the left side
2x² + 2x - 4x - 4 = 36
2x² - 2x - 4 = 36 ( subtract 36 from both sides )
2x² - 2x - 40 = 0 ( divide through by 2 )
x² - x - 20 = 0 ← in standard form
(x - 5)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 4 = 0 ⇒ x = - 4
But x > 0 ⇒ x = 5
Answer: x=5

Step-by-step explanation:
We are required to simplify the expression: [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})[/tex]
This is a product and the first thing we will do is to collect like terms:
[tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{1/2}x^{1/4}y^{1/3}y^{1/6}[/tex]
Next, we apply the addition law of indices: [tex]x^a X x^b =x^{a+b}[/tex]
[tex]x^{1/2}x^{1/4}y^{1/3}y^{1/6}=x^{1/2+1/4}y^{1/3+1/6}\\\\=x^{3/4}y^{1/2}[/tex]
Therefore, [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{3/4}y^{1/2}[/tex]

Answer:
No he is not correct.
Step-by-step explanation:
Both points lie at point -8. Knowing this, we also know that to find the answer we would subtract the two coordinates not add them. We do this because they lie in the same quadrant. Therefore, | 12 | - | - 3.5 | = 8.5 units apart.

solve each equation for 0≤x≤360
cos(x+45°)+cos(x-45°)= √2
Answer:
0°
360°
Step-by-step explanation:
We want to solve the equation,
[tex] \cos(x + 45) + \cos(x - 45) = \sqrt{2} [/tex]
We expand using trigonometric identities to get;
[tex]\cos(x) \cos( 45) - \sin(x) \sin(45) + \cos(x) \cos( 45) + \sin(x) \sin(45) = \sqrt{2} [/tex]
[tex] \frac{ \sqrt{2} }{2} \cos(x) - \frac{ \sqrt{2} }{2} \sin(x) + \frac{ \sqrt{2} }{2} \cos(x) + \frac{ \sqrt{2} }{2} \sin(x) = \sqrt{2} [/tex]
Simplify;
[tex] \cos(x) - \sin(x) + \cos(x) + \sin(x) = 2[/tex]
Simplify;
[tex]\cos(x) + \cos(x) = 2[/tex]
Add
[tex]2\cos(x) = 2[/tex]
Divide by 2
[tex]\cos(x) = 1[/tex]
Take cosine inverse;
In the
[tex]x = \cos^{ - 1} ( 1) =0\degree [/tex]
Also in the 3rd quadrant cosine ratio is positive.
[tex]x = 360-0= 360 \degree[/tex]

What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The block has the following dimensions:
( L x w x h ) = ( 8 x 5 x 6 ) in
We will determine the surface area of each unique face of the block given in the attachment.
Surface area of the face ( 8 x 5 ):
Area = ( 8 )×( 5 )
Area = 40 in²
Surface area of the face ( 8 x 6 ):
Area = ( 8 )×( 6 )
Area = 48 in²
Surface area of the face ( 6 x 5 ):
Area = ( 5 )×( 6 )
Area = 30 in²
Hence, Create a stack where the 6-inch-by-8-inch faces of the blocks touch is the correct strategy for stacking the blocks
