Answer:
Number of fruit flies after 14 days is equal to 1880.
Step-by-step explanation:
given,
fruit flies at the beginning of the experiment = 200 fruit flies
rate of increase of fruit flies = 5 per hour
to calculate the number of flies after 14 days.
time = 14 days = 14 × 24 = 336 hours
flies after 14 days = initial number of flies + rate of increase × time
= 200 + 5 × 336
= 1880 fruit flies.
hence,Number of fruit flies after 14 days is equal to 1880.
Answer:
for the first picture: 2.16
Step-by-step explanation:
12% of 18 is 2.16:
-convert 12 % to a decimal so 0.12 times 18
also, 12 % percent is 0.12 as a decimal because you move the decimal 2 places to the left to get .12
- multiply 0.12 times 18 to get 2.16 as the answer
I hope this helped for the first pic!
The formulas for arc length and area of a sector are quite close in their appearance. The formula for arc length, however, is related to the circumference of a circle while the area of a sector is related to, well, the area! The arc length formula is

. Notice the "2*pi*r" which is the circumference formula. The area of a sector is

. Notice the "pi*r squared", which of course is the area of a circle. In our problem we are given the arc length and the radius. What we do not have that we need to then find the area of a sector of the circle is the measure of the central angle, beta. Filling in accordingly,

. Simplifying by multiplying by 360 on both sides and then dividing by 36 on both sides gives us that our angle has a measure of 60°. Now we can use that to find the area of a sector of that same circle. Again, filling accordingly,

, and

. When you multiply in the value of pi, you get that your area is 169.65 in squared.
you could ride 6 rides + the admission and it would equal $33. so the all day pass is cheaper than 6 or more rides :)
I believe it is d.
Equation is y= 1/2x.
When a number or fraction is next to a variable that means to multiply.
So let’s replace the variable,x, with 6.
If you multiply 1/2 by 6, you get 3.
If you multiply 1/2 by 24 you get 12.
