Assume that the distance from Earth to the moon is exactly 238,855 miles and that it took astronauts 75 hours to reach the moon in 1969. How far did the astronauts travel each hour, on average, during their trip to the moon?
Answer: They traveled 3,184.733333333333
Step-by-step explanation: Do 238,855 divided by 75 (The three keeps going on forever).
mark the other guy brainliest because he is correct it is B or 3,184.73 (the 3 has a line over it)
238,555 ÷ 75 = 3,184.733333333

Choice 3
can someone help me with these questions please?
Answer:
1. One solution
2. No solution
Step-by-step explanation:
1.Step 1: Subtract 2x from both sides.
5x+3−2x=2x−3−2x
3x+3=−3
Step 2: Subtract 3 from both sides.
3x+3−3=−3−3
3x=−6
Step 3: Divide both sides by 3.
3x + -6
3 2
x=−2
Answer:
1)One solution
2)No solutions
Step-by-step explanation:
To solve this for the first one you should add both sides by three to get the constants on one side.
5x+3+3=2x
Combine like terms.
5x+6=2x
Get x to one side by subtracting 5x on each side.
6=-3x
Solve for x.
x=6/-3 or x=-2
Which means one solution.
To solve the second one you should o all the steps above, but to find:
8=3
Which is not true, so no solutions.

A boat travled 27 miles in 2 hours. At this rate, how many miles will the boat travel in 1/2 hour ?
Answer:
54 miles
Step-by-step explanation:
Just divide the 27 miles to the half hour and you will see how many miles the boat travelled. In 27 miles in 2 hours is 13.5 miles so we figured out what we get in two hour so to find out for the half an hour you do the same thing
Answer:
6.75 miles.
Step-by-step explanation:
1/2 is 1/4 of 2 hours, so you'd take 1/4 of 27 (which is 27/4) and you would get 6.75.
If that explanation is a little difficult to understand, let me know and I will rephrase!
Your mother bought several full packets of eggs. She opened all the packs and kept all the eggs in the fridge. You later counted all the eggs and found there are 46 eggs. One single packet looks as shown below. Do you think shopkeeper cheated your mother? Justify.
Answer:
Even when the answer is not complete, most likely yes, she was cheated.
Step-by-step explanation:
The question does not include how a packet looks, however since the total egg count is 46 units, this number is only divisible by 2 and 23.
So unless each egg packet contains 2 or 23 eggs, any other size would mean a packet had less eggs than expected.
Usually eggs come in packs of 6 or 12 units, so to sum 46 eggs or more you would need:
If 6 eggs per packet:
46/6 = 7,66 packets -> she must have bought 8 packets and should have 48 eggs, meaning there are 2 eggs missing.
If 12 eggs per packet:
46/12 = 3,83 packets -> she must have bought 4 packets and should have 48 eggs, meaning there are 2 eggs missing.
That's why it is safe to assume some packets had less eggs than expected.

A group of five friends goes to the state fair. Each friend pays the entrance fee and buys one booklet of ride tickets and a meal ticket. The entrance fee is d dollars. A booklet of ride tickets costs 2.5 times the entrance fee. A meal ticket costs $4 less than the entrance fee. Which part of the expression represents the total amount each friend pays?
A) d+2.5d+d
B) d+2.5d+d-4
C) 2.5d
D) 5
Answer:
for the second part its d+2.5d+d-4
Step-by-step explanation:
The part of the expression represents the total amount each friend pays is d+2.5d+d-4.
What is Expression?An expression is combination of variables, numbers and operators.
Each friend pays for the entrance fee, a booklet of ride tickets, and a meal ticket.
The entrance fee costs d dollars.
A booklet of ride tickets costs 2.5 times the entrance fee, which is 2.5d dollars.
A meal ticket costs $4 less than the entrance fee, which is (d - 4) dollars.
Therefore, the total amount each friend pays is:
d + 2.5d + (d - 4)
Simplifying the expression, we get:
4.5d - 4
Hence, d+2.5d+d-4 is the part of the expression represents the total amount each friend pays.

Can you find the m∠DCA.
Answer:
D. (116)
Step-by-step explanation:
The angles are congruent. So, we can set them equal to each other.
4x = 6x - 58
58 = 2x
x = 29
Now plug it in for x.
4(29) = 116
Alejandra correctly wrote the equation y – 3 = y minus 3 equals StartFraction 1 Over 5 EndFraction left-parenthesis x minus 10 right-parenthesis.(x – 10) to represent a line that her teacher sketched. The teacher then changed the line so it had a slope of 2, but still went through the same point. Which equation should Alejandra write to represent the new line?
Answer:
The equation Alejandra should write to represent the new line should be
y-3 = 2(x-10)
Step-by-step explanation:
The equation Alejandra wrote for the line her teacher sketched is
y-3 = 1/5 (x-10).
This can be related to the equation of a line in point slope form. The equation of line in point slope form
is
y - y₁ = m (x - x₁)
Where (x₁, y₁) is a point on line
and m is the slope of the line.
Hence, for the equation Alejandra wrote
The line went through point (3,10) and the slope of the line is 1/5.
Now, from the question
The teacher changed the line so it had a slope of 2, but still went through the same point. That is, the line still went through point (3,10).
In the new line the teacher sketched, the values of x₁ and y₁ remain the same but the value of the slope (m) has changed.
The slope of the new line is 2, that is, m =2.
Therefore,
The equation that represents the new line is
y-3 = 2(x-10)
Hence, the equation Alejandra should write to represent the new line should be y-3 = 2(x-10).

Answer: C, B, A, D
Step-by-step explanation:
1. option C
f(x) = 2x² - 1
f(-1) = 2(-1)² - 1
= 2(1) - 1
= 2 - 1
= 1
2. option B
f(x) = 2x - 5
11 = 2x - 5
16 = 2x
8 = x
3. option A
f(x) = 2x - 5
f(3) = 2(3) - 5
= 6 - 5
= 1
4. option D
f(x) = x² + 7

Henry incorrectly said the rate 1/3 pound / 1/9 gallon can be written as the unit rate 1/27 pound per gallon. What is the correct unit rate? What was Henry´s likely error?
Answer:
The unit rate is 3 pounds per gallon.
Henry's likely error could have been that he multiplied instead of dividing.
Step-by-step explanation:
Given the rate 1/3 pound / 1/9 gallon, this can be written in the unit rate by dividing 1/3 pound by 1/9 gallon. First, we will evaluate 1/3 divided by 1/9 and the unit will be in pound per gallon.
1/3 divided by 1/9 can be written as
[tex]\frac{1}{3} \div \frac{1}{9}[/tex]
This then becomes
[tex]\frac{1}{3} \times \frac{9}{1}[/tex]
[tex]\frac{1}{3} \times \frac{9}{1} = \frac{9}{3} = 3[/tex]
Hence, the unit rate is 3 pounds per gallon.
Henry's likely error could have been that he multiplied instead of dividing. That is, he multiplied 1/3 by 1/9, Such that he gets
[tex]\frac{1}{3} \times \frac{1}{9}[/tex]
[tex]\frac{1}{3} \times \frac{1}{9} = \frac{1}{27}[/tex]
Hence, the 1/27 pound per gallon he got.
