Mai received and spent money and the following ways last month. For each example write a sign number to represent the change in money from her perspective.
A. Her grandmother gave her $25 in a birthday card.
B. She earned $14 by babysitting.
C. She spent $10 on a ticket to a concert.
D. She donated three dollars to a local charity.
E. She got two dollar interest on money that was in her savings account
By knowing how to use positive numbers and negative numbers, we will see that the answers are:
A) C = $25B) C = $14C) C = -$10D) C = -$3E) C = $2How to represent each change?
By standard notation, if May wins money, then we represent this with a positive number.
While if she pays or has a debt, we represent the change with a negative number (because now she has less money than before).
A) She receives $25, so the change is:
C = $25
B) She earns $14, so the change is:
C = $14
C) She spends $10, so now she has $10 less than before, the change is:
C = -$10
D) She donated $3, so the change is:
C = -$3
E) She gots $2, then the change is:
C = $2.

Samantha spent 40 minutes on homework. Sixty percent of that time was spent on language arts. How many minutes were spent on language arts?
A 2-column table with 10 rows titled Time Spent. Column 1 has entries 10 percent, 10 percent, 10 percent, 10 percent, 10 percent, 10 percent, 10 percent, 10 percent, 10 percent, 10 percent. Column 2 has entries 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes.
Answer:
24 Minutes
Find 60 percent of 40.
Percent means over 100
,so 60% = 60/100 or 0.6
Multiply that by 40 to find 60% of it:
40 * 0.6 = 24
A Samantha spent percent 24 minutes on language arts out of the 40 minutes dedicated to her homework.
To find the number of minutes Samantha spent on language arts, to calculate 60% of the total time spent on homework.
Samantha spent a total of 40 minutes on homework.
To find 60% of 40 minutes, multiply 40 by 0.60 (since 60% is equivalent to 0.60):
60% of 40 = 0.60 × 40 = 24 minutes
Therefore, Samantha spent 24 minutes on language arts.
Regarding the 2-column table provided, it appears to be unrelated to the problem and does not directly provide information about Samantha's homework time. It contains entries for "Time Spent" in percentages and corresponding minutes, but these percentages and minutes do not seem to relate to the given problem.

As stated elsewhere, two conditions must be met.
There are 3 angles in a triangle.They must add to 180Answers A B and C all meet these 2 conditions. It is only D that gives you the problem.
It adds to 181 which is not 180. 180 is written in stone, A triangle cannot have 179 degrees, nor can it have 181 degrees.
It must have 180.
D has 181 degrees. It cannot be a triangle.

Jason went shopping.
He bought a watch and a pair of trainers for a total price of £53.55
This price includes a 15% loyalty discount.
Before the discount, the trainers were priced at £38.
Work out the price of the watch before the discount.
53.55 / 85 = 0.63
0.63 * 100 = 63
63 - 38 = 25
watch was 25 before discount
what is the exact and approximate area of a circle with a diameter of 6 feet? For the approximate area, round your answer to the nearest tenths place
Answer:
Exact: 9.42
Approx: 9
Step-by-step explanation:
The area of a circle is pi*radius^2 (pi=3.14 r=radius ^2= power of 2/squared)
The diameter is two times the radius. So, we need to divide the diameter by two for the first step of solving this.
6/2=3
Now, we know the radius is 3.
Let's square it:
3^2= 3*3
3*3=9
Now, the last step is to multiply it by pi (3.14)
3.14*3=9.42
There we go! The area is 9.42 feet!

Really need help on this
Answer:
x = 3, x = 1
Step-by-step explanation:
Okay, let's set the equation = 0:
3x^2 -12x + 9 = 0
Then, we factorise. To do this, we have to find 2 numbers which have a product of 9 and add up to -12. There are a few ways to do this, but a simple try and error is the easier when using numbers which don't have many factors. So here we know that to get a product of 9, there are only 2 options: 9*1 and 3*3. Now we have to figure out which of these add up to -12. But to do this, we have to take into account the 3, from the x^2 coefficient. This allows to know that the numbers will be 9*1. Then we just need to change the signs to make it work. This would give: -9*-1 (with 3*-1).
The fully factorised equation would be (3x-9)(x-1). Following this, you can always expand it quickly, to check that it really works correctly.
Now let's solve. (3x-9)(x-1) = 0
We say that when two numbers multiplied by each other equal to zero, one of them has to be zero. So if (3x - 9) was equal to 0:
3x - 9 = 0
3x = 9
x = 9/3
x = 3/1
x = 3
Now for the other:
x - 1 = 0
x = 1

The plane height is down 110 feet from its initial height.
What is subtraction?Subtraction is mathematic operation. Which is used to remove terms or objects in expression.
Let x be the initial height of the plane.
Then according to question;
if drop down means height in negative term and rise up means height in the positive term.
Then,
the height is
