Answer:
Step-by-step explanation:
To find miles per hour, divide miles by hours:
(15 mi)/(3 h) = 15/3 mi/h = 5 mi/h
__
To find distance, multiply speed by time.
(5 mi/h) × (10 h) = 50 mi
To solve this problem you must apply the proccedure shown below:
1. You must apply the Law of Cosines, as you can see in the figure attached. Then:
- The first ship travels at 
in for two hours. Therefore, the side 
is:
- The second ship travels at 
for 
. Therefore, the side 
is:
- Now, you can calculate 
:
The answer is: 
Answer:
Step-by-step explanation:
This is a multiplication problem.
We want to multiply 
We factor to get:
We now cancel out the common factors to get:
We now multiply the numerators and the denominators separately to get.
This simplifies to
Therefore the simplified expression is
Answer:
Each person gets one eighth of the pie.
Step-by-step explanation:
1/2 pie divided by 4.
1/2 / 4 = 1/2 / 4/1 = 1/2 × 1/4 = 1/8
Answer: Each person gets one eighth of the pie.
Answer:
m<T = , m<M = and m<Z =
Step-by-step explanation:
From the given ∆TMZ, let the measure angle T be represented by T.
So that,
m<M = 2T + 6°
m<Z = 5T - 50°
Sum of angles in a triangle =
T + (2T + 6°) + (5T - 50°) =
8T - =
8T = +
=
T =
=
Therefore,
i. m<T =
ii. m<M = 2T + 6°
= 2 x + 6°
=
m<M =
iii. m<Z = 5T - 50°
= 5 x - 50°
= - 50°
=
m<Z =
