Answer:
The hurricane traveled 260 miles per hour.
Step-by-step explanation:
Given,
Distance covered by hurricane = 130 miles
Then time = 
hours=
hour
Distance=Speed*Time
Speed=
Speed=
Speed=260 miles per hour
So, the hurricane traveled 260 miles per hour
This is going to require a good bit of division. I am going to turn the mixed fractions into improper fractions. Remember that to divide fractions, you take the 2nd fraction, flip it, and multiply.
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
Answer:
1
Step-by-step explanation:
2x^2 + x -1 = 2
2x^2 + x-1-2 = 0
2x^2 + x -3 = 0
2x^2 -2x + 3x-3 = 0
2x(x-1) + 3(x-1) = 0
(2x + 3)(x-1) = 0
2x + 3 = 0
or x-1 = 0
x = -3/2 or 1
First answer: 6 and 8
6 + 8 = 14
6 * 8 = 48
Second answer: 14 in the middle, 350 on top.
39 - 25 = 14
25 * 14 = 350
Answer:
A
Step-by-step explanation:
We require to find ∠ A
Subtract the sum of the given angles from 180
∠ A = 180° - (85 + 53)° = 180° - 138° = 42°
Using the Sine rule in Δ ABC, that is
= 
, that is
= ( cross- multiply )
AC × sin42° = 85 × sin85° ( divide both sides by sin42° )
AC = 
≈ 126.6
