Answer:
x-y=2.5,xy=21
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
One of the numbers is x.
The other number is y.
The difference between two numbers is 2.5
This means that x - y = 2.5
The product of those two numbers is 21.
This means that xy = 21.
So the two equations are: x-y=2.5,xy=21
Create a scatter plot with depth temperature
*Time is the X value on the horizontal axis. There are two data series for the Y values: Actual temperatures and and predicted temperatures.*

You deposited $125 in a savings account that earns a simple interest rate of
1.75% per year. You earned a total of $8.75 in interest. For how long was your
money in the account?
9514 1404 393
Answer:
4 years
Step-by-step explanation:
Each year, the interest earned is ...
0.0175 · $125 = $2.1875
Then the time it took to earn $8.75 in interest was ...
$8.75/(2.1875/year) = 4 years
Ray starts walking to school at a rate of 2 mi/h. Ten minutes later, his
sister runs after him with his lunch, averaging 6 mi/h.b. Solve the system
to determine how much time it took Ray's sister to catch up to him.
Your answer
Answer:
Ray walks 15 minutes prior to his sister and walk for 5 minutes to catches up
Step-by-step explanation:
The computation of the time taken is as follows:
Let us assume the Ray time be t
So his sister time would be t - 10
Since Ray distance is 2t
So his sister distance is 6(t - 10) = 6t - 60
As the distance is the same
So, the following equation must be made
2t = 6t - 60
-4t = -60
t = 15
Therefore Ray walks 15 minutes prior to his sister and walk for 5 minutes to catches up
Natalie bought a 3 - pack of erasers for $1.47. How much did each eraser cost?
Answer:
Each eraser costs $0.49
Step-by-step explanation:
If three erasers cost $1.47, and you have to find the value of one eraser, all you have to do is divide $1.47 by three.
1.47 ÷ 3 = 0.49
To prove this, you can multiple 0.49 by three.
0.49 × 3 = 1.47
Therefore, your answer will be $0.49 per eraser.
(Remember to add the money symbol because some hardcore teachers won't accept the answer without it, or will deduct points. The symbol looks like this: $)
Answer:
$0.49
Explanation:
1.47 divided by 3 is 0.49.

Please help! I need to remember this!
Answer:
1/16
Step-by-step explanation:
Answer:
[tex]\frac{1}{16}[/tex]
Step-by-step explanation:
For this type of problem, I do KCF (Keep, Change Flip)
⅛ ÷ 2
Keep the fraction (⅛)
Change the sign to a multiplication (×)
Flip the "2" to its reciprocal ([tex]\frac{1}{2}[/tex])
Now we have a new expression
[tex]\frac{1}{8}[/tex] × [tex]\frac{1}{2}[/tex]
Now we multiply from across
The numerator × Numerator
The denominator × denominator
1 × 1 = 1
8 × 2 = 16
Our answer will be....
[tex]\frac{1}{16}[/tex]
Hope this helped!

Tara needs an $8,000 personal loan.
Which loan option would require her to pay back the least amount of money?
36-month loan with a 9% annual simple interest rate
42-month loan with a 7% annual simple interest rate
48-month loan with an 8% annual simple interest rate.
54-month loan with a 6% annual simple interest rate
The least amount is paid back in a 42-month loan with a 7% annual simple interest rate.
What is simple interest?The term simple interest refers to a type of interest that is paid only on the principal and not on the interest. We have to note that the time and the interest rate all contribute to increasing the amount of money to be paid back.
In the first case, the amount to be paid back is;
A = $8,000 + ($8,000 * 9 * 3/100)
= $10160
In the second case;
A = $8,000 + ( $8,000 * 7 * 3.5/100)
A =$ 9960
In the third case;
A = $8,000 + ($8,000 * 8 *4/100)
A = $10560
In the fourth case;
A = $8,000 + ($8,000 * 6 * 4.5/100)
A = $10160
Hence, the least amount is paid back in a 42-month loan with a 7% annual simple interest rate.

If mGHJ = 27 and mGHK = 87, what is the measure of mJHK
Answer:
114 degrees
Step-by-step explanation:
From the letters that describe the rays, these two angles are adjacent to each other, and therefore, if the measure of one is 27 degrees and that of the other one is 87 degrees, then the larger angle defined by the two rays (HJ and HK) with common vertex H would be:
m<JHK = 27 degrees+ 87 degrees = 114 degrees

Are the two triangles above similar? Why or why not?
A. Yes, they are similar by the AA similarity postulate.
B. Yes, they are similar by the SAS similarity theorem.
C. No, there is not enough information given to prove similarity.
D. No, right triangles are never similar.
No, Triangles with one congruent angle are never similar so the correct option is D.
What is similar triangle?Similar triangles are triangles that have constant form, however their sizes might vary. All equal triangles, squares of any aspect lengths are samples of similar objects. In other words, if 2 triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.
For AAA similarity postulate; Two triangles are similar if two corresponding angles of them are of same measure. It is because when two pairs of angles are similar, then as the third angle is fixed if two angles are fixed, thus, third angle pair also gets proved to be of same measure.
If the triangles, have only 1 congruent angles , it can not be said similar because for a triangle to be similar , minimum two criteria must be equal .
Hence we can conclude that triangles with one congruent angle are never similar.
