Answer:
Science Test
Step-by-step explanation:
Math test:
24/30 so divide 24 by 30 to see the percentage she got, which is 80%
Science test:
21/25, same process as before, 21 divided by 25 is 84%
Therefore, she scored higher on the science test.

Answer : rotation of 90 counterclockwise° about the origin and then translation 2 unit up.
Explanation : In Δ RST, it is an right triangle with ∠R being the right angle. When we draw this triangle we see that long side of the Δ is close to the origin and the short one is below ∠R.
Now, Δ R'S'T', is also a right triangle. But he long side is parallel to the y axis and ∠S' is now above ∠R' instead of ∠S being to right of ∠R in the original Δ.
which clearly shows that the Δ is rotated at 90 degrees counter clockwise.
On drawing a new Δ; The point R" is at (1,-4), S" at (1,-1), and T" at (2,-4).
All three of these points are 2 units below the points R' S' T'.
We need to translate the triangle 2 units higher.
Therefore, the answer is to perform rotation of 90 counterclockwise° about the origin and then translation 2 unit up.
Answer:
y-25=180
Step-by-step explanation:
Same line so 180 degrees.
Answer:
P = $6923
Step-by-step explanation:
The simple interest formula is given by
1) I = principal *interest rate * time period
where I is the interest
The amount due after the time period is given by:
2) T = principal + I
After three months, you have $9.000, so T = 9000. The present value P is the principal. We have that:
9000 = P + I
I = 9000 - P
In our problem, we have that the time period is 3 months and out interest rate is 10%.
Replacing in 1)
9000 - P = P*0,1*3
9000 = 0.3P + P
1.3P = 9000
P = $6923
So the present value P is $6923
