Answer:
Step-by-step explanation:
We have the length of AC which is opposite angle B; we also have the length of the hypotenuse. We will use trig here to solve for angle B. The sin ratio is the one that fits.
sin(B) = side opposite / hypotenuse:
so
sin(B) = .9411764706
Now we will use the 2nd button on our calculators. This will give us the missing angle value. Press 2nd then sin and you will see on your screen:
Enter that decimal after the open parenthesis and hit "enter" to get
B = 70.25 or 70°
Answer:
a.
b.
Step-by-step explanation:
Given
Solving (a): Round to the nearest hundredth thousandth
This means there would be 5 digits after the decimal.
So:
-- (approximated)
(b) Express in standard form
A number in standard form has the following format;
Where
So:
becomes
This is because the decimal point was moved 5 places backwards
Approximate 4.167 to nearest integer; We have:
Answer: (Width x = 7) (Length 10)
Step-by-step explanation:
(x+3) + = 34/2
2x + 3 = 17
2x = 14
x = 7 -----------Width
10 ---------------Length
Answer:
number: 1,3,5
Step-by-step explanation:
How much does it cost to buy 10 computer mice (not the living thing :) ) that are $24.75 each.
10(24.75)=247.5
It will cost $247.5
