Which expression calculates the time in hours an object takes to travel 38 miles at a speed of 2 m/h ? (I NEED HELP ASAP)
defon

Answer:

Option B : 38/2 is the correct answer.

Step-by-step explanation:

Given that:

Distance to travel = 38 miles

Speed of object = 2 miles per hour

Distance = Speed * Time

To find the time, we will divide the distance by speed.

Time = \frac{Distance}{Speed}

Putting values of distance and speed in the formula.

Time = 38/2

Hence,

Option B : 38/2 is the correct answer.

bruce is playing with a set of base-ten blocks. he has 65 ten-blocks and 7 one-blocks. what is the value of his blocks
Oksi-84 [34.3K]
The 65 tens blocks can be solved by doing 65x10 which is 650.  the 7 ones blocks can be solved by 1x7  which is 7 so you then add up 650 and 7 to get a grand total of 657

Approximate the real number solution(s) to the polynomial function f(x) = x3 − 4x2 + x + 6.
vredina [299]
C is the answer. Solutions to a polynomial are numbers that, when plugged into the equation, make the equation equal zero

So if you plug 3, -1, or 2 into x^3 - 4x^2 + x + 6, it will equal zero.
