Answer:
9/12
Step-by-step explanation:
because I is the biggest number
The exponent of 12 tells of how many prizes to count to the left of the decimal. Another example of how a scientific notation can make numbers easier to read is the diameter of a hydrogen atom, which is about 0.00000005 mm, and in Scientific notation is 5x10-8 5x10 -8mm.
Answer:
Step-by-step explanation:
Since cotangent of angle is:
And
- cos λ = x/1, sin λ = y / 1
The value of cot λ is:
- cot λ = x/y = - 0.358/0.934 = - 0.383 (rounded)
Correct choice is B
Answer:
Step-by-step explanation:
If you subtract the extra 12 quarters from the total, you have $4.55 that can be made up of groups of 1 quarter and 1 dime. Since those groups are worth $0.35, there are $4.55/$0.35 = 13 of them.
There are 13 dimes and 13+12 = 25 quarters in the purse.
Answer:
The system of inequalities is
Step-by-step explanation:
step 1
Find the equation of the solid blue line
Let
Find the slope of AB
The equation of the line into slope intercept form is equal to
we have
----> the point A is the y-intercept
substitute
-----> equation of the solid blue line
The solution of the inequality is the shaded area above the solid line
therefore
The first inequality is
step 2
Find the equation of the dashed red line
Let
Find the slope of CD
The equation of the line into slope intercept form is equal to
we have
----> the point C is the y-intercept
substitute
-----> equation of the dashed red line
The solution of the inequality is the shaded area below the dashed line
therefore
The second inequality is
The system of inequalities is
