Answer:
1/3
Step-by-step explanation:
Answer:
Write 21 in the soup column and 25 in the peanut butter column.
Explanation:
The ratio of cans of soup to jars of peanut butter was 7:5
If the jars of peanut butter were 15, then the cans of soup would be (7/5 × 15) = 21
If the cans of soup were 35, then the jars of peanut butter would be (5/7 × 35) = 25
Answer:
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
Step-by-step explanation:
8 cos^2 x + 4 cos x-4 = 0
Divide by 4
2 cos^2 x + cos x-1 = 0
Let u = cos x
2 u^2 +u -1 =0
Factor
(2u -1) ( u+1) = 0
Using the zero product property
2u-1 =0 u+1 =0
u = 1/2 u = -1
Substitute cosx for u
cos x = 1/2 cos x = -1
Take the inverse cos on each side
cos ^-1(cos x) = cos ^-1(1/2) cos ^-1( cos x) =cos ^-1( -1)
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
2^2 = 4
just think 2 written out TWO times (hence the SECOND power).
Answer:
9.71 miles
Step-by-step explanation:
total miles he ran = 6.19 + 3.1 = 9.29
Target = 19 miles
Goal for sunday = 19 - 9.29 = 9.71
