Answer:
=8 1/4 as a fraction or 8.25 in decimal form.
Step-by-step explanation:
The indicated operation is the product of the two fractions. Multiplication opens the brackets.
(-11/2)×(-3/2)
=(-11×-3)/(2×2)
=33/4
The negative signs before each term cancel out in multiplication and division.
=33/4 =8 1/4= 8.25
Choose 1 answer among the improper fraction, Mixed fraction or the decimal.
Answer:
Step-by-step explanation:
Given that,
We need to find the value of cos x.
We know that,
Using the above relation,
So, the value of cos x is equal to 
.
Answer:
229.2
Step-by-step explanation:
Remark
There's a lot in this question. The x is not just any x. It is defined and limited by its relationship with the sine function.
The Sin is defined as Opposite over Hypotenuse in a right triangle. The 670 is the Hypotenuse. You know that by the definition of Sine.
So one thing you should always keep in mind: the x because of where it is in the definition, will always be smaller than the Hypotenuse. So you should get a value less than 670.
Formula
Just as you have it
Sin(20) = x / 670
Solution
Multiply both sides by 570
670 * sin(20) = x
sin(20) = 0.3420
x = 670 * 0.3420
x = 229.2
For a question like this you need to find the surface area
The formula is :
b x w x h (base x width x height)
So you multiply 3 1/2 x 6 x 5 1/2 = 22.5
