Step-by-step explanation:
We know that the shape of moon is sphere.
The volume of sphere is given by :-
[tex]\text{V}=\dfrac{4}{3}\pi r^3[/tex], where r is the radius of sphere.
Given : The diameter of moon = 2155 miles
Then the radius of moon=[tex]\dfrac{2155}{2}[/tex]
Then , the volume of moon is given by :-
[tex]\text{V}=\dfrac{4}{3}\pi (\dfrac{2155}{2})^3=1667978979.2\pi\approx1667978979\pi \text{ cubic miles}[/tex]

the lines shown below are perpendicular. if the green line has a slope of 1/7, what is the slope of the red line?
Answer: it's -7
Step-by-step explanation:
Answer:
Therefore, the slope of the red line must be -7
Step-by-step explanation:
If the two lines are said to be perpendicular each other, then the multiplicative of their slope is -1.
Let "m1" be the slope a line and "m2" be the slope of the perpendicular line.
So, m1*m2 = -1
Here, let's take "m1" be the slope of the green line and "m2" be the slope of the red line.
They said to be perpendicular to each other.
So, m1*m2 = -1
Given: m1 = 1/7
NOw plug in m1 = 1/7 in the above statement, we get
1/7 *m2 = -1
Let's find the value of m2, multiply both sides by the reciprocal of 1/7
The reciprocal of 1/7 is 7.
7*1/7*m2 = -1*7
7/7.m2 = -7
m2 = -7
Therefore, the slope of the red line must be -7
What is the answer to this.

30=3/5
so 10 miles = 1/5 on the map
there re 5/5 per inch, so 4 inches = 4*5 = 20/5
20*10 = 200
so they are 200 miles apart
A store sells cooking oil of two different brands in bottles of the same size. The table below and the equation each show the price (y) in dollars of different numbers of bottles of oil (x)
Brand A
Number of bottles (x).

5
Price (dollars) y
22
33
44
55
Brand B:
Y=17x
How many dollars more is the price of 8 bottles of Brand B than the price of 8 bottles of Brand A oil?
The number of dollars more is the price of 8 bottles of Brand B than the price of 8 bottles of Brand A oil is:
$ 48
Step-by-step explanation:Brand A--
Number of bottles (x) Price (dollars) y
2 22
3 33
4 44
5 55
The function that represents the relation between the price of the bottles and the number of bottles is:
y=11x
Brand B--
Also, the price of the bottles depending on the number of bottles is:
Y=17x
According to Brand A the price of 8 bottles is: y=11×8=$ 88
and according to Brand B the price of 8 bottles is: y=17×8= $ 136
Also, the difference in the price of Brand B to that of Brand A for 8 bottles is:
$ 136-$ 88
= $ 48

What are the solution(s) of –x2 + 2x + 3 = x2 – 2x + 3?
a. 1 and 3
b. 0 and 2
c. 0
d. 3
HURRY IM BEING TIMED!!
Answer:
Step-by-step explanation:
Given: –x² + 2x + 3 = x² – 2x + 3 .
To find: What are the solution(s) .
Solution: we have given that
–x² + 2x + 3 = x² – 2x + 3 .
On subtracting both side by x² .
-2x² + 2x + 3 = x² - x² - 2x + 3
-2x² + 2x + 3 = -2x +3
On Addition both side by 2x .
-2x² + 2x + 2x + 3 =-2x +2x +3
-2x² + 4x + 3 = 3
On subtracting both side by -3 .
-2x² + 4x + 3 -3 = 3 - 3
-2x² + 4x = 0
Taking common 2x .
2x (- x +2 ) =0 .
On grouping .
2x= 0
so x= 0
Now , -x +2 =0 .
-x = -2 .
On dividing by -1
x= 2
Therefore , option B is 0 and 2 .
s the work shown below correct? Explain your answer. (11 + 2i ) – (3 – 10i ) = 11 + 2i – 3 – 10i = (11 – 3) + (2i – 10i) = 8 – 8i
Answer:
Given that: [tex](11+2i)-(3-10i)[/tex]
Remove the parentheses, we have;
[tex]11+2i-3+10i[/tex]
Like terms are those terms which have same variables to the same power.
Combine like terms of a constant variable;
[tex](11-3) +2i+10i[/tex]
Similarly, combine like terms of imaginary part, we have;
[tex](11-3) +(2i+10i)[/tex]
Simplify:
[tex]8 +(12i)[/tex]
or
[tex]8+12i[/tex]
Therefore, the correct solution of [tex](11+2i)-(3-10i)[/tex] = [tex]8+12i[/tex]
Holly earns $30 for babysitting 5 hours. She earns $28 when she does chores for 4 hours. Which compares the unit rates?
The rate of earning money for both activities will be calculated by dividing the amount earned by the total time spent for each of the activity.
Babysitting: rate = ($30 / 5 hours ) = $6 / hour
Doing chores: rate = ($28 / 4 hours) = $7 / hour
Thus, Holly is able to earn money faster when doing the chores compared to when she do the babysitting if she work for the same amount of time for each.
Answer:
The unit rate for doing chores is $1 more than the unit rate for babysitting.
Step-by-step explanation:
30 divided by 5=6 So that means it was six dollars for babysitting.
28 divided by four=7 So that means it was seven dollars for babysitting.

(1-sec x)/(1-cos x) = -sec x
I got up to this:
(cos x - 1)/ (cos x(1 - cos x)
Can you help me verify the following identity?
We are given the trigonometric equation:
(1 - sec x) / (1 - cos x) = - sec x
Since the left side has more terms, then let us work on that side to make it exactly like the right side.
We know that sec = 1 / cos, therefore:
(1 – 1 / cos x) / (1 – cos x) = - sec x
[(cos x – 1) / cos x] / (1 – cos x) = - sec x
[- (1 – cos x) / cos x] / (1 – cos x) = - sec x
Cancelling out the term (1 – cos x):
- 1 / cos x = - sec x
- sec x = - sec x

The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F:
F = 9 over 5 C + 32
Which of the following formulas correctly solves for C?
A) C = 5F − 32 over 9
B) C = 5 F over 9 − 32
C) C = 9 over 5 (F − 32)
D) C = 5 over 9 (F − 32)
it is the last option C=5/9(F-32)
Answer:
option (D) is correct.
formula that solves for C is [tex]C=\frac{5(F-32)}{9}[/tex]
Step-by-step explanation:
Given : the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F as , [tex]F=\frac{9}{5}C+32[/tex]
We have to find the correct formula that solve for C,
Consider the given formula,
[tex]F=\frac{9}{5}C+32[/tex]
We have to find formula for C,
Thus, first subtract 32 both side, we get,
[tex]F-32=\frac{9}{5}C[/tex]
Now, multiply 5 both side, we get,
[tex]5(F-32)={9}C[/tex]
Now , divide both side by 9, we get,
[tex]\frac{5(F-32)}{9}=C[/tex]
Thus, formula that solves for C is [tex]C=\frac{5(F-32)}{9}[/tex]
Thus, option (D) is correct.

given that there are eight ounces in a cup and four cups in a quart, which quantity below is equal to 128 ounces
256 ounces 64 ounces 18 cups 4 quarts
Answer:
4 quarts i had this question on a test and got it right
Step-by-step explanation:
128 ounces is equal to 4 quarts.
To solve this, we need to convert the amount given in ounces to quarts.
Step-by-Step Solution:
There are 8 ounces in a cup.There are 4 cups in a quart.Therefore, there are 8 ounces/cup × 4 cups/quart = 32 ounces in a quart.To find out how many quarts are in 128 ounces, divide 128 by 32: 128 ounces / 32 ounces per quart = 4 quarts.So, the quantity equal to 128 ounces is 4 quarts.
The other options: 256 ounces and 64 ounces are obviously not equal to 128 ounces since 256≠ 128≠ 64
and, 18 cups =18×8= 144 ounces ≠ 128 ounces.
