Answer:

167.47 \: {cm}^(3)

Step-by-step explanation:

V_(cone) = (1)/( 3) \pi {r}^(2)h \n \n = (1)/( 3) \pi * {4}^(2) * 10 \n \n = (1)/( 3) * 3.14 * 16 * 10 \n \n = (1)/( 3) * \: 502.4 \n \n = 167.466667 \n \n = 167.47 \: {cm}^(3)

If the principal is $350 and the interest rate is 3 percent, what is the simple interest earned in one year?simple interest = Pxrxt

Answers

Answer:

The simple interest was found to be $9.6 after 1 year at 3%

Step-by-step explanation:

Given that

principal p= $350

rate r= 3%= 3/100= 0.03

time t= 1 year

The expression for the simple interest is given as

SI= p*r*t

SI= 320*0.03*1

SI= $9.6

After 1 year at 3% the simple interest is $9.6

Answer:

2.700 × 10-7

Step-by-step explanation:

Answer:  2.7*10^-4

step by step explanation:

1. Make the number a new number between 1 and 10

More Icon

Move the decimal point to make 0.00027 a new number between 1 and 10. Because our original number is less than one, we move the decimal point to the right. Drop any zeroes in front of the number. Keep track of how many times we move the decimal point.

0.00027 -> 2.7

Our new number is 2.7. We moved the decimal point 4 times.

2. Define the power of 10

More Icon

Because our original number was less than one, the exponent defining the power of 10 is negative. Remember, we moved the decimal point 4 times, so the exponent is negative 4

10^(-4)

3. Final result

2.7*10^(-4)

Use the quadratic formula to solve the equation 2y^ +6y-8=0

Answers

To solve this problem you must apply the proccedure shown below:

 1. You have the following quadratic equation, which is given in the problem above:

 2y^2+6y-8=0

 2. So, to solve it, you can use the quadratic formula, which is:

 y=(-b±√(b²-4ac))/2a

 a=2
 b=6
 c=-8

 3. When you susbtitute these values into the formula, you obtain:

 y1=-4
 y2=1
