Answer:
No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate
=> 52 + 3w >= 90
Step-by-step explanation:
Given that Antonina needs to have worked at least 90 volunteer hours to graduate means that she needs to volunteer either for 90 hours or more than that . Mathematically this can be written as
Total volunteer hours required to graduate greater than or equal to 90
Total volunteer hours required to graduate>= 90
No. of hours already volunteered = 52
no. of hours left for volunteering = Total volunteer hours required to graduate - No. of hours already volunteered = 90 - 52 = 38
No. of hours in one week she can dedicate for volunteering= 3
if w is the number of weeks that Antonina needs to tutor in order to complete her volunteer hours
then total volunteer hours dedicated in w weeks will be = w*No. of hours in one week she can dedicate for volunteering = w*3 = 3w
Thus,
No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate
=> 52 + 3w >= 90
Answer:
That's strange wording.
Anyway as far as perfect cubes we have 10^3 = 1,000 and then the next cube is 1,331 which is 11^3
So basically you are asking what do we multiply 1,176 by, in order to get a perfect cube?
1,331 / 1,176 = 1.13180272108844
So, to make 1,176 a perfect cube, multiply it by 1.13180272108844

I'm pretty sure it's 1/12, please don't be mad if I got it wrong
Answer:
5.89 feets
Step-by-step explanation:
Arc length :
L = θ/ 360° * 2πr
Diameter = 15 ; Radius, r = 15 / 2 = 7.5
θ = 45°
L = (45/360) * 2*3.14 * 7.5
L = 0.125 * 2 * 3.14 * 7.5
L = 5.89 feets

Answer:
- tan(A) = 7/24
- sin(A) = 7/25
- cos(A) = 24/25
Step-by-step explanation:
The mnemonic SOH CAH TOA can help you remember the trig ratios:
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
With respect to angle A, the sides are Adjacent = 24; Opposite = 7, Hypotenuse = 25. Then the desired trig ratios are ...
tan(A) = 7/24
sin(A) = 7/25
cos(A) = 24/25
