1) 1/4+1/2
We need to convert the fractions.
1/4 is fine.
1 x 2=2
2 x 2=4
1/4+2/4=3/4
2) a+a
a can be written as 1a.
1a+1a=2a
I can't see photos and he doesn't know 3 or 4 and i'm confused on 5.
a=?
Hope it helps?
Answer:
Step-by-step explanation:
The cube root of 15,409,000 = 248.84 yards.
There are 1760 yards in a mile
One edge of a cube = 248.84 / 1760 = .141386 miles.
So a cube would be .00283cubic miles. Your answer does not reach a hundredth place, I don't think.
Answer:
The value of angle is 56.9°
Step-by-step explanation:
First, you have to find the length of hypotenuse using Pythagoras' Theorem, c² = a² + b² :







In order to find θ, you have to apply Sine Rule :





Let D = difference between mean and median of data.
Mean = (22 + 8 + 10 + 18 + 12 + 20)/6
Mean = 90/6
Mean = 15
Let m = median
m = 8, 10, 12, 18, 20, 22
m = (12 + 18)/2
m = 30/2
m = 15
D = M - m
D = 15n- 15
D = 0
