Hey There

In multiplication you have to know the process of regrouping, which means to take away from tens. Also, you multiply from left to right.

Steps
1. First multiply 5*5=25, the two adds to the product of 5*2 

2. Now you have to multiply 5*2=10, now you have to add two because of regrouping, 10+2=12, so you're final answer is 125.

In conlusion, 25*5=125

Hope this helps :)

   2      5

×          5
___________
 1    2    5
____________

1st step:  5 × 5 = 25.  Put down 5 . Keep 2 aside.

2nd step:  5 × 2 = 10. 10 plus the 2 kept aside = 12

3rd step :  write down 12.

That brings the answer to 125.

The data for resort A shows more consistency because a larger interquartile range such as the one for resort B, shows more variation. This means that the snowfall for resort A is more likely to be close to the median.

If 12 workers can dig a tunnel in 100 days, how long will it take 20 workers to dig the tunnel
Paraphin [41]

Answer:

60 days.

Step-by-step explanation:

This is  a proportion question. You compare two ratios. Unfortunately it is an inverse ratio.

12 = k/100                   Multiply both sides by 100

1200 = k

20 = k/x                       Multiply both sides by x

20x = k

20x = 1200                 Divide by 20

20x/20 = 1200/20

x = 60 days.  

An inverse proportion works by making a constant k. The  constant k makes the days shorter when the number of people increases. You should expect that. More people , less time.

What is the inverse of the function f(x) = 2x + 1? h(x) = 1/2x - 1/2
sweet-ann [11.9K]

Answer:

h(x) = x/2 - 1/2

Step-by-step explanation:

Here's the procedure for finding the inverse function algebraically:

1.  Replace the label 'f(x)' with the label 'y:'  y = 2x + 1

2. Interchange x and y:  x = 2y + 1

3.  Solve the resulting equation for y:  2y = x - 1, or y = (1/2)(x - 1) or y = x/2 - 1/2

This result corresponds to the 1st given possible answer choice.

The desired inverse function is h(x) = x/2 - 1/2
