Answer:
58
Step-by-step explanation:
The midsegment has a length that is the average of the lengths of the parallel sides it is halfway between.
... LM = (38 +78)/2 = 116/2 = 58
Scientific notation is a way of writing numbers in a form of a decimal multiplied by an exponent of 10.
For these, the exponent will be negative, since they're teeny tiny decimals, and we'll have to move the decimal point back to the right.
0.00000012 will become
This is because the decimal point is moved seven places to the right of where it originally was.
0.000005008 will become

Again, this is because the decimal point is moved seven places to the right of where it originally was.
So, your scientific notations are

and
So if her pay check is x she spends 0.25x on the dress and 0.125x on shoes. That’s 0.375 when added together.
So 0.375x + 24=60
0.375x = 60-24
0.375x= 36
X=36/0.375
X=$96
Answer: 
=========================================================
Explanation:
Use the pythagorean trig identity
and plug in the fact that 
Isolating sine leads to
. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,

Answer:
Saving=£450
Spent=£200
Step-by-step explanation:
Ratio of saving to spending is 9:4
She inherits £650
So to determine her saving
It will be
9+4=13
Since her saving is 9
So, 9/13 × 650
5850/13
=450
So her saving is£450
To determine what she spent
4/13 × 650
2600/13
200
Saving=£450
Spent=£200
