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 :)

4h+7=4h-3 i think i have it but im not sure 100% so i need hlp
SSSSS [86.1K]

                                                 <u>4h + 7 = 4h - 3</u>

Subtract  4h  from each side:            7 = -3

There is no value of  ' h ' that can make this a true statement,
so the equation has no solution.

A cyclist rides his bike at a rate of 5 kilometers per hour.what is this rate in
il63 [147K]

Answer:

rate is 8 miles per hour and he travels 40 miles per 5 hours

Step-by-step explanation:

The story problem told that i should assume that 1 mile is 1.6 km

so 5km/hr is equal to 8m/h

i got it by multiplying 5 by 1.6 so i can change from the unit km to mile

so about the miles per 5 hours just multiply the 8 mph by 5 so it is 40

40miles per 5hrs

hope i made it clear
