Which planet in the chart is most likely Earth? Yeah
Does somone no the answer
Answer:
Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.Step-by-step explanation:

Mary reduced the size of a painting to a width of 3.3 in what is the height if it was originally 32.5 in tall and 42.9 in wide?
Answer: 2.5 in
Step-by-step explanation:
From the question, we are informed that Mary reduced the size of a painting to a width of 3.3 in even though the original width was 42.9 in wide. This shows that the size of the painting was 3.3/42.9 = 1/13
Therefore, the height of it was originally 32.5 in will be:
= 1/13 × 32.5
= 2.5 in
Therefore, the height is 2.5 in.

Which of these statements are correct about two parallel lines in a coordinate plane? Select three that apply.
If they are each translated 7 units to the left, they will remain parallel.
If they are each reflected across the line y = x, they will remain parallel.
If they are each rotated 180° about the origin, they will not remain parallel.
If they are each reflected across the x–axis, they will not remain parallel.
If they are each rotated 270° about the origin, they will remain parallel.
If they are each translated 9 units down, they will not remain parallel.
Answer:
If they are each rotated 180° about the origin, they will not remain parallel.
If they are each translated 7 units to the left, they will remain parallel.
If they are each rotated 270° about the origin, they will remain parallel.
Step-by-step explanation:
I got them!!!!!!!!!!!!!!!!
If they are each rotated 180° about the origin, they will not remain parallel, If they are each translated 7 units to the left, they will remain parallel and If they are each rotated 270° about the origin, they will remain parallel are true statements.
What is Coordinate Geometry?Coordinate geometry (or analytic geometry) is defined as the study of geometry using the coordinate points.
Parallel lines are coplanar infinite straight lines that do not intersect at any point.
Among the given statements the following are true.
If they are each rotated 180° about the origin, they will not remain parallel.
If they are each translated 7 units to the left, they will remain parallel.
If they are each rotated 270° about the origin, they will remain parallel.
Hence, If they are each rotated 180° about the origin, they will not remain parallel, If they are each translated 7 units to the left, they will remain parallel and If they are each rotated 270° about the origin, they will remain parallel are true statements.

Answer:
x = 3.6
Step-by-step explanation:
It can be helpful to write down corresponding sides and their measures.
AB = 5, PQ = 6
BC = 3, QR = x
CD = 2, RS = 2.4
DA = 4, SP = 4.8
Then you can look for easy ways to find x. You can tell from this table that all of the values in PQRS are 6/5 = 1.2 times the corresponding values in ABCD.
Then ...
QR = 1.2×BC = 1.2×3
QR = x = 3.6
_____
Other ways you can figure x are ...
x/BC = PQ/AB
x = (BC)(PQ/AB) = 3(6/5) = 3.6 . . . . the method we used
__
x/RS = BC/CD
x = 2.4(3/2) = 3.6
__
x/SP = BC/DA
x = 4.8(3/4) = 3.6

Peter bought 8 lemons for 6$ Each lemon was the same price.
Answer: Each lemon costs $0.75 cents (seventy five cents)
Step-by-step explanation:
0.50 x 8 is the same as "half" of 8. This is $4. That is too low so.. 0.75 cents
6 ÷ 8 = 0.75
Each lemon costs $0.75 or 75 cents.
Determine the length of the line segment with the end points at (9, 6) and (-12, 6).
Answer:
Step-by-step explanation:
You are given two points whose y values are the same. There is no need to use the distance formula. The x values alone will give you the length of the line.
to get to the y axis you have to go 12 units to the right.
To get from the y axis to 9, you have to go 9 more units to the right.
The total is 9 + 12 = 21
If you insist to see this done with the formula, it would look like this.
d = sqrt( y2 - y1)^2 + (x2 - x1)^2 )
y2 = 6
y1 = 6
x2 = -12
x1 = 9
d = sqrt ( (6 - 6)^2 + (-12 - 9)^2 )
d = sqrt( 0 + ( -21 )^2 )
d = sqrt( 441)
d = 21 the same thing you got just be reasoning it out.
The first method works only if either both xs are the same or both ys are the same.

Kiran has $100 saved in a bank account. (The account doesn’t earn interest.) He asked Clare to help him figure out how much he could take out each month if he needs to have at least $25 in the account a year from now.
He could take out $6.25 for each month and at the end $25 also left in his account.
What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the data given in the question,
The total amount Kiran is having in the bank = $100
He needs to have at least $25 in the account at the end of the year.
So, the money he can spend in a year = $100 - $25 = $75
1 year = 12 months
So, the amount of money spent per month will be,
75/12 = $6.25
