a = 1
b = 2
r = 4
(x-a)² + (y-b)² = r²
(x-1)² + (y-2)² = 4²
(x-1)² + (y-2)² = 16
Answer: 40
Step-by-step explanation:
Number of correct questions Sally got = 28 questions
Percentage of correct questions answered= 70% on the exam,
Total number of questions in the exam = Unknown
Let the total questions in the exam be represented as y.
Since Sally got 70% correctly, this will be:
70% of y = 28
70/100 × y = 28
0.7 × y = 28
0.7y = 28
Divide both side by 0.7
0.7y/0.7 = 28/0.7
y = 40
There are 40 questions in the exam.
Answer:
1/2 or 0.5 (same value, different form)
Step-by-step explanation:
Ok...since I can't actually graph it, we can make a table out of it....
x y
7 -1
9 0
From -1 to 0, we add 1 (this is for the y section)
From 7 to 9, we add 2 (this is for the x section)
Now all we have to do is divide the y with the x
y/x = 1/2
The slope will be 1/2 (fraction form) 0.5 (decimal form)
Hope this helped!
Answer:
15,300 + 18750 + 13,500 + 23,400 +19500 = 90,450
Step-by-step explanation:
divide all the numbers by 100, then multiplying by 3
<u>Answer:</u>
The correct answer option is 21.
<u>Step-by-step explanation:</u>
We know that the given lines PW and AD intersect at the point C.
Therefore, the two given angles are equal to each other and we can write them in the form of an equation as:
(4x - 4)° = (3x + 17)°
Solving for x to get:
4x - 4 = 3x + 17
4x - 3x = 4 + 17
x = 21
Therefore, the value of x is equal to 21.
