Answer:

The  factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factor pairs are 1 and 42, 2 and 21, 3 and 14, 6 and 7.

Step-by-step explanation:

The given number is 42.

The numbers that can divide 42 completely, are the factors of 42.

Since we know that 42 is completely divisible by  1, 2, 3, 6, 7, 14, 21 and 42, therefore the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.

The list of factor pairs are shown below:

1\times 42=42

2\times 21=42

3\times 14=42

6\times 7=42

Therefore the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factor pairs are 1 and 42, 2 and 21, 3 and 14, 6 and 7.

Factors of 42 are...
1, 2, 3, 6, 7, 14, 21, and 42.
1 x 42 = 42
2 x 21 = 42
3 x 14 = 42
6 x 7 = 42

Don't know how you want your table.
I'm sure you can do it yourself.

What number is 15% of 63
Degger [83]
Take the number (63) and then divide it with 100, this gives you 1%. Then you want to multiply with with 15 in order to get 15%. The answer becomes:

\frac{63}{100}\cdot 15=9.45

I need help for this question please!!!!

Answer:

a. 35 degrees

b. 145 degrees

Step-by-step explanation:

a. Since the two base angles of this triangle are congruent, we can conclude that the triangle is <em>isosceles, </em>which means that the two base angles and sides are congruent.

Now, knowing that information, we can subtract 110 from 180 (the sum of all interior angles in a triangle) and we get 70. But this isn't our answer. This is the sum of both base angles. Since the base angles are congruent, we can divide the 70 by 2 to get the measure of ONE base angle, which is 35 degrees.

b. There are two approaches to solve this problem. I have worked both out.

1) We can use the Exterior Angle Theorem, which states that the sum of the interior angles is equal to the exterior angle. We can add 110 to 35, so we get 145 degrees as the measure of <1.

2) The second approach is supplementary angles. Since we see that one of the base angles and <1 is on the same line, we can subtract 35 from 180 to find the measure of <1 to get 145 degrees.

Either way you use, you get the correct answer. Hope this helped!
