Answer:
40
Step-by-step explanation:
360 divided by 9 = 40
To find the denominator we find the total number of students. 35 + 13 + 22 + 10 = 80. The numerator is the number of students for Website A. Now we got a fraction 35/80. Now to simplify it we keep dividing 35 and 80 till we can't divide it anymore without going into decimals. 35 / 5 = 7. 80 / 5 = 16. We got 7/16. We can't divide it anymore because 7 is a prime number. So there's your answer. 7/16.
Answer:
4.) d
5.) b
6.) c
7.) a
Step-by-step explanation:
I'm a pro at Geometry..sometimes, but with angles I'm a pro!!
4.) d) The Alternate Interior angles are <7 and <12
5.) b) The consecutive interior angles are <4 and <10
6.) c) The corresponding angles are <13 and <15
7.) a) The alternate exterior angles are <1 and <14
Hope this helps ya!!
X + y = 7
xy = -30
x + y = 7
x - x + y = -x + 7
y = -x + 7
xy = -30
x(-x + 7) = -30
x(-x) + x(7) = 30
-x² + 7x = -30
-x² + 7x + 30 = 0
-1(x²) - 1(-7x) - 1(-30) = 0
-1(x² - 7x - 30) = 0
-1 -1
x² - 7x - 30 = 0
x² - 10x + 3x - 30 = 0
x(x) - x(10) + 3(x) - 3(10) = 0
x(x - 10) + 3(x - 10) = 0
(x + 3)(x - 10) = 0
x + 3 = 0 or x - 10 = 0
- 3 - 3 + 10 + 10
x = -3 or x = 10
x + y = 7 or x + y = 7
-3 + y = 7 or 10 + y = 7
+ 3 + 3 - 10 - 10
y = 10 or y = -3
(x, y) = (-3, 10) or (x, y) = (10, -3)
The two numbers that add up to 7 and multiply to 30 are -3 and 10.
In order to know that, you need to divide 28 from 126
It would be:126/28 = 4.5
So, your final answer is 4.5
Hope this helps!
