You can make this easier by separating the numbers.

Let's split up 49 first.

You would split this into 40 and 9.

Then, split 45 into 40 and 5.

Multiply the numbers from the ones place (5 and 9) to get 45.

Then multiply the numbers in the tens place (40 and 40).

If you do 4 times 4 it equals 16, and with the two 40's all you have to do is add two zeros., which makes it 1,600.

Then, add both of those numbers (1,600 and 45) up to get 1,645.

If you are asking for 45 times 49 then the answer is 2115

if you are asking fo the smallest number that 45 and 49 will multiply into the the answer is gotten by
45=7*5
49=7*7
answer=7*7*5=245

How do I solve this literal equation? <br> 15 points

Answer:

$\pi = \frac{A}{2r^2 + 2rh}$

Step-by-step explanation:

First, we need to isolate $\pi$ by taking it common from both terms on the right:

$A=2\pi r^2 + 2\pi rh\\A=\pi (2r^2 + 2rh)$

Now, since we want $\pi$ in terms of the other variables, we can divide the left hand side (A) by whatever is multiplied with $\pi$ on the right hand side. Then we will have an expression for $\pi$ . Shown below:

$A=\pi (2r^2 + 2rh)\\\pi = \frac{A}{2r^2 + 2rh}$

This is the xpression for $\pi$

A data set of with whole numbers has a low of 20 and a high value of 89

Vikentia [17]

Answer:

The range is 69

Step-by-step explanation:

We have that the least value of the data set is 20 and the highest value is 89.

From the available information, we can only find the range of the data set.

The range is the highest value minus the least value.

This implies that, the range is $89-20=69$

Is there any video related to this or can you explain how to do it

Angles ECD and CEF add to 180

40+140 = 180

So that means we have EF parallel to CD (due to the same side interior angle theorem)

--------------

Angles BCE and ECD combine to 30+40 = 70, which is congruent to angle ABC = 70 as well.

In other words, this shows angle ABC = angle BCD. Both of these angles are alternate interior angles. Since they're congruent, they lead to AB being parallel to CD.

--------------

So far we have

AB || CD

CD || EF

Using the transitive property, we can then link the two statements to say AB || EF. Think of a chain where CD is the common link. We go from AB to CD, then from CD to EF. So we can just take a single path from AB to EF.

It's like saying "P --> Q and Q --> R, therefore P --> R"
