The two horizontal lines are parallel, so the smaller triangle is similar to the entire triangle.
That means the sides are proportional to each other. So pick two sides of the triangle and find the ratio between them. The ratio must be the same for both triangles.
(15/5) = (15+x)/8
Solve for x.
15*8 = 5(15+x)
120 = 75 + 5x
5x = 45
x = 9
The most reasonable description of the two populations for her conclusion is business and nursing students in the classes that were surveyed at Diablo Valley College (DVC).
Step-by-step explanation:
The question itself indicates that., For a statistics project, a community college student at Diablo Valley College (DVC) decides to investigate cheating in two popular majors at DVC in order to find out the most academic cheaters.,
also the researcher( student) convinces the professors who teach business and nursing courses at DVC to distribute a short anonymous survey in their classes. So., The most reasonable description of the two populations for her conclusion is business and nursing students in the classes that were surveyed at Diablo Valley College (DVC).
Answer:
218
Step-by-step explanation:
first find the area of the circle-
to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).
Now I know the height is 12. Find the area of the triangle
subtract the area of the triangle from the area of the circle
314-96=218
Answer:
-- (a)
-- (b)
Step-by-step explanation:
Given
Variation: Direct
A = 8; m = 20
First, represent the variation.
Represent as an equation
Make k, make the subject
A = 8; m = 20; So
When m = 20, we have:
When A = 7, we have:
Answer:
432
Step-by-step explanation:
Okay so george and his dad plant 18 to a row and 3 rows an hour. So thats 3 rows of 18 an hour.
So first: Multiply 18 x 3 to find out how many trees they plant each hour.
18 x 3 = 54: So they plant a total of 54 plants each hour.
Next: to find out how many they planted in 8 hours multiply 54 plants x 8 hours
54 x 8 = 432 trees per 8 hours
Hope it helps :P
