sum of all positive integers up to 1000
Step-by-step explanation:
995. Therefore, the sum of all positive integers up to 1000, which are divisible by 5 and not divisible by 2 is 50000.
Use the graph to determine which statement describes f(x).
5.
y=f(x)
-5
5
--5
O A. f(x) does not have an inverse function, because its graph fails the
vertical line test.
O B. f(x) does not have an inverse function, because its graph fails the
horizontal line test.
c. f(x) has an inverse function, because its graph passes the
horizontal line test.
Last year there were 20 girls on the volleyball team. This year the number of girls DECREASED by 10%. How many girls are on the volleyball team this year
Answer:
18
Step-by-step explanation:
There are 18 girls on the team this year.
If you take 20 and divide the number by 10 you will get 2.
10%=2
If you multiply 2x10 you get 20.
20-2=18

Find the slope of line 2, which is parallel to line 1. Line i goes through the points
(-13, -6), (7, 15).
(-13, -6), (7, 15) = 1.05
Equation: y = 1.05x + 7.65.
The entered points belong to an increasing, linear function.
Answer:
m = rise / run = 21/20, or m = 1.05
Step-by-step explanation:
If the lines are parallel, their slopes are identical. So we can find the slope of line 1 and know that it's also the slope of line 2.
From (-13, -6) to (7, 15), the x-component increases by 20 units from -13 to 7. Thus, the "run" in m = rise / run is 20. Likewise, the "rise" is 21.
Thus the slope in question is m = rise / run = 21/20
Aubree is making different shades of pink paint to use for an art project. A batch of dark pink uses 2.5 cups of red paint and 1.5 cups of white paint. A batch of light pink uses 0.75 cup of red paint with 1.25 cups of white paint. She begins with a gallon of red and a gallon of white paint. How much of each color paint will she have left if she makes a batch of dark pink and light pink every day for a week?
Answer:
Cups of red paint for a batch of dark pink - 2.5
Number of gallons of red paint that she starts with - 1
Cups of red paint for a batch of light pink - i did not get that one

Angles in a triangle equal 180
45 + 47 = 92
180 - 92 = 88
Answer:
88
Step-by-step explanation:
The two other angles add up to 92. Because the angles of a triangle, 180-92=y. We subtract to get 88.

the perimeter of a right angled triangle is 12cm and the hypotunos is 5 cm find the value of other two sides
Answer: The other two values are 3 and 4. This is because it is the only value which fits the formula a^2 + b^2 = c^2 (which will be 5^2 in our case). Also 3,4, and 5 is a well known right angle side length.
