Answer: 10 km in one hour
Step-by-step explanation:
If there are nine hours, and we need to find the distance it will cover in one hour, then we need to divide 90 by 9.
90 ÷ 9 = 10
A train covers 10 km in one hour.
Hope this helps!
Answer:
48
Step-by-step explanation:
2 = 2 line 1
2 + 4 = 6 line 2
2 + 4 + 6 = 12 line 3
The next line we would add 12 since we are adding the sum of the previous line
2 + 4 + 6 +12 = 24 line 4
The next line we would add 24 since we are adding the sum of the previous line
2 + 4 + 6 +12+24 = 48 line 5

Find the length of Samson's shadow
The question can be illustrated with the attached figure where Samson's shadow is represented with x.
To solve for x, we make use of the following equivalent ratios:
Convert to fraction
Cross Multiply
Make x the subject
<em>Hence, Samson's shadow is 40ft</em>
The first option is the right one.
You have to find the greates common divisor of the coefficientes, which is -6 and then divide each momomial with lead to: -6 (m^2 + -3m + 6).
You can verifiy the result by multiplying -6 times the polynomial inside the parenthesis, using the distributive property.
