Answer:
6.27 minutes
Step-by-step explanation:
1/10 of 2.1 is 0.21 and 2.1+0.21=2.31 and if there final time is 3.96 then to find the original time you must add them 2.31+3.96=6.27
First, you need to determine the possible side lengths of your third side. Here, your third side can be your hypotenuse or another side length. If it is your hypotenuse, it will be equal to sqrt(8^2+5^2)=sqrt(64+25)=sqrt(89). If it is your side length, it will be equal to sqrt(8^2-5^2)=sqrt(64-25)=sqrt(39). You can find the difference by subtracting these from each other in a calculator, making your difference equal to sqrt(89)-sqrt(39)≈3.2 inches.
Step-by-step explanation:
g(x)=x³/8 +16
y=x³/8 +16
x³/8=y-16
x³=8(y-16)
x=³√{8(y-16)}
7x^2 - 12 = 0
7x^2 = 12 | : 7
x^2 = 12/7 | sqrt
x = sqrt(12/7)
x = sqrt(84) / 7
x = 2sqrt(21) / 7
He sold 28 at 0.75 cents and sold 21 at 0.99 cents.
0.85 is between 0.75 and 0.99 so he sells between 21 and 28 donuts.
0.85 is closer to 0.75 ,so the number should be closer to28.
The answer should be b)25
