It would take Julia 3.66666667 miles to travel 66 miles. This is because to get the answer, you divide the amount of miles you want to travel by the number of MPH. When you divide 66/18, that would equal 3.66666667

Use the formula V=6s2 to find the surface area of a cube with the sides of length a = 1/3 cm

ruslelena [56]

Answer:

$V = \frac{2}{3} cm^2$

Step-by-step explanation:

Given

$V = 6s^2$

Required

Find the surface area when the length is $\frac{1}{3}\ cm$

To do this, we simply substitute $\frac{1}{3}\ cm$ for s in the given formula

$V = 6s^2$ becomes

$V = 6 * \frac{1}{3}^2$

$V = 6 * \frac{1}{3} * \frac{1}{3}$

Combine Fractions

$V = \frac{6 * 1 * 1}{3 * 3}$

$V = \frac{6}{9}$

Simplify Fraction

$V = \frac{2}{3} cm^2$

Solve for y 11(y-2)+3y=-7y+14

Greeley [361]

11y - 22 + 3y = -7y + 14
*combine like terms*
14y - 22 = -7y + 14
21y = 36
y = 36/21 = 12/7 or 1 5/7

hope this helps :)

What is the scientific notation of 0.00165?

Ierofanga [76]

Answer:

The answer is $1.65*10^{-3}$

Step-by-step explanation:

when writing scientific notation, there must be one number to the left of the decimal point.

To achieve this in this problem, you need to move the decimal point 3 times to the right.

because you are moving the point to the right, the exponent will be negative.

*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*

therefore you answer should be written as:

$1.65*10^{-3}$

hope this helps :)
