Question is Incomplete; Complete question is given below;
James and Amy played 12 games of checkers last week. This week they played 7 games on Monday and 2 games on Wednesday.James and Amy play 3 more games. They have played the same number of games as last week. Fill in the blanks to make the equation true. Use +,-, or =. 12_7_2_3 Explain how you chose the symbols.
Answer:
12<u> = </u>7<u> + </u>2<u> + </u>3
Step-by-step explanation:
Given:
Number of games played last week = 12
Number of games played on Monday this week = 7
Number of games played on Wednesday this week = 2
Also given:
James and Amy play 3 more games.
So Number of games played more = 3
We need to fill in the blanks 12 __ 7__2__3 with signs '+', '-','='.
Solution:
It is given that they have played the same number of games as last week.
So we can say that;
Number of games played last week is equal to Number of games played on Monday this week plus Number of games played on Wednesday this week plus Number of games played more.
framing in equation form we get;
Hence we have fill the blanks as 12<u> = </u>7<u> + </u>2<u> + </u>3.
The correct answer is x^2-2x+2=0
The explanation is shown below:
1. To solve the problem shown in the figure above, you must apply the following proccedure:
2. You have that the roots of the quadratic equation shown in the figure attached in the problem are:
x=-1±i
3. Then, you know the quadratic formula to solve quadratic equations, which is:
(-b±√(b^2-4ac))/2a
4. You can see in the figure that a=1 and c=2; then, by analizing this, you can conclude that the coefficient b is:
b=-2
5. Therefore, you can conclude tha the quadratic equation is:
x^2-2x+2=0
6. If you want to verify it, apply the quadratic formula to the quadratic equation shown above and you will obtain the roots shown in the figure.
Answer:
so the answer is 10
Step-by-step explanation:
g(x)=×+7+1
2+7+1
10
This has a lot of scary words and numbers in it, but it's all just fluff.
That big ugly formula is nothing but numbers, except for the 'h' in it
near the end. When you write your altitude in place of 'h' and push
all the numbers through your calculator, the answer is the air pressure
at that altitude.
All it's asking you to do is this:
-- Write ' 100 ' into the big formula.
-- Run all the numbers through the calculator and get the pressure at 100 meters.
-- Then write ' 1000 ' into the formula.
-- Run the whole thing through the calculator again, and see what
the pressure is at 1,000 meters.
-- Subtract, and see how much the pressure changed between 100 meters
and 1,000 meters.
You want to know what I think the whole idea is here ? I think the whole idea
is to get you to decide which things to do first as you calculate the formula,
AND to give you practice in using your calculator to do weird stuff.
In the formula, I see a power, a set of parentheses, two multiplications, and
one subtraction. You have to decide what order to do them in. And THEN,
you have to figure out how to do them all with your calculator.
Here's the order:
-- Inside the parentheses, multiply 2.25577x 10⁻⁵ by 'h' .
-- Inside the parentheses, subtract the result from ' 1 '.
-- Take the number inside the parentheses, and raise it to the 5.25588 power.
-- Then multiply the result by 101,325 .
For 100 meters altitude, the pressure you should get is 100,129 pascals.
Make sure you can get that with your calculator when you put '100' in place
of 'h'. And then, when THAT works, do it with 1,000 in place of 'h'.
The number you get for 1,000 meters should be about 10,254 pascals less.
Answer: $11,155
Step-by-step explanation: For this problem, first we will use the "Simple Interest" equation to find the total interest earned after three years.
First, convert 3.85% to a decimal, 0.0385.
I, interest = 10,000 x 0.0385 x 3
I = 1,155
Now add the total interest $1,155 to the total deposit $10,000.
1,155 + 10,000 = $11,155
