A positive angle less than 360 that is coterminal with -725 degrees is
The positive angle is less than 360 which is coterminal with -725 degrees is 85 degrees.
What are Coterminal Angles?Coterminal angles are those with the same beginning side and the same terminal sides. These angles are in the typical position, although their values differ. They have the same sides, are in the same quadrant, and their vertices are identical. The endpoint sides coincide at the same angle when the angles are rotated clockwise or anticlockwise.
An angle that is coterminal with -725 degrees is an angle that has the same initial and terminal sides as -725 degrees, but its measure is between 0 and 360 degrees.
To determine a positive angle less than 360 that is coterminal with -725 degrees, we can add or subtract multiples of 360 from -725 degrees until we get an angle within that range.
In this case, -725 degrees - (2 x 360) = -725-720= -1445.
So, the positive angle less than 360 that is coterminal with -725 degrees is -1445 degrees + 360 = 85 degrees.

24.. A toy company makes 40 plastic harmonicas in 30 minutes. At this
rate how long will it take to make 200 harmonicas?
Proportions
Answer:
It will take 2 and a half hours
Step-by-step explanation:
Well 40 can go into 200 5 times so you would do 5 times 30 minutes which would be 150 minutes and then you would divide it by 60 to simplify which would be 2 hours and 30 minutes. So it will take 2 and a half hours to make 200 harmonicas.
200/40 = 5
5 * 30 = 150
150/60 = 2 hours and 30 minutes
Answer:
6.7 minutes
Step-by-step explanation:
From what we know, we will have to divide. The things we are dividing are the 30 minutes it took to make the 40 plastic harmonicas and the total we need of harmonicas, which is 200. By dividing 200 by 30, we get 6.666666666666667. But, we can't have that long answer, so we need to round up. Which is when we get our quotient of 6.7 minutes. If I'm wrong, please, don't be afraid to correct me. And have a good day stranger!
Edit: This answer is wrong. I was corrected and now I know what the answer is. Please do avoid this answer. But have a good day to anyone sees this!
Describe several methods you could use to determine the rational zeros of a polynomial function. Which would you choose to use first? Explain.
Answer:
The Rational Zero Theorem helps us to narrow down the list of possible rational zeros for a polynomial function. Once we have done this, we can use synthetic division repeatedly to determine all of the zeros of a polynomial function.

What is the surface area of a right circular cylindrical oil can, if the radius of its base is 4 inches and its height is 11 inches? for 25 points
Step-by-step explanation:
Given
Radius (r) = 4 inches
height (h) = 11 inches
Total surface area of cylindrical oil can is
= 2πr ( r + h)
= 2 * 22 / 7 * 4 ( 4 + 11)
= 2 * 22/7 * 4 * 15
= 377.14 inches ²
If the radius of a right circular cylindrical oil can base is 4 inches and its height is 11 inches, then the surface area of that right circular cylindrical oil can is 376.99 square inches.
What is the surface area of a right circular cylindrical figure?Let b and h be the radius of the base and height of a right circular cylindrical figure respectively. Then the surface area of this right circular cylindrical figure is 2πb(b + h).
How to solve this problem?Given that the radius of the base of the can is 4 inches.
The height of the can is 11 inches.
Then the surface area of the can = 2π * 4(4 + 11) = 8π(15) = 120π = 376.99 square inches
Therefore, If the radius of a right circular cylindrical oil can base is 4 inches and its height is 11 inches, then the surface area of that right circular cylindrical oil can is 376.99 square inches.

Jazzmine took out a loan of $17,500 to buy a new car. She received a 3.5% interest rate compounded annually and paid $3,274.50 in interest. How long did it take Jazzmine to pay off the loan?
Answer:
Time period = 5 year (Approx.)
Step-by-step explanation:
Given:
Amount of loan = $17,500
Rate of interest = 3.5% compounded annually
Amount paid as interest = $3,247.5
Find:
Time period
Computation:
Using compounded interest formula
I = P[(1+r)ⁿ - 1]
3,247.50 = 17,500[(1+3.5%)ⁿ - 1]
3,247.50 = 17,500[(1+0.035)ⁿ - 1]
3,247.50 = 17,500[(1.035)ⁿ - 1]
Time period = 4.948
Time period = 5 year (Approx.)

Option B is correct. [tex] \checkmark [/tex]How many zeros are in the product 4 x 10 7th power
Answer:
7 or 40,000,000
Step-by-step explanation:
The exponent (^7) is how many zeros for the 10. if there is 10^2 its just 100 because it's 10 * 10 or 100 (notice the zeros in the 10 * 10 equation? yup, there's 2) and the 4 is basically 4 * 10, it changes the 10 like 4*1 but with a lot of zeros if there were exponents (10^2) so just put them together and you get 4 * 10^7
10^7 (its just 10 times itself 7 times) = 10,000,000
4 * 10,000,000 = 40,000,000
