The trip was 6 hours long.
Step-by-step explanation:
Given,
The time to go to the island = 1 hours.
The return trip took 3/4 of the time of the original trip.
To find the time of the trip.
Let,
The time of the original trip is x hours.
The time for returning =
According to the problem,
1 + = x
or, x - =
or, =
or, x = ×4 = 6 hours
Hence,
The trip was 6 hours long.
Answer:
(14.7 , 16.9)
Step-by-step explanation:
it is given that tons
σ=3.8 tons
n=49
at 95% confidence level α=1-.95=0.05
=1.96 ( from the standard table)
at 95% confidence level the coefficient interval for μ is
(14.7, 16.9)
Answer:
107
Step-by-step explanation:
Since we know that the triangles have the same 3 sides, they are congruent (SSS). We also know that a triangle's angles add up to 180 degrees.
We first need to add 41 and 32 to give us the number we need to subtract from 180.
41+32=73
Now we need to subtract from 180 degrees.
180-73=107
If 107 is the measure of angle D, then according to SSS congruence it is also the measure of angle B.

Answer:
16, 30, 34 YES 12, 18, 30 NO
Step-by-step explanation:
I just know :)
Start: 21.5
After Tacos: 21.5*(1-1/4)=21.5*(3/4)=16.125
Used For Burgers: 16.125*(2/3)=10.75
Burgers: 10.75/(1/4)=10.75*4=43
