Answer:

40°

Step-by-step explanation:

According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.

So with this, you need to add 70° and 70°.

You get 140°

Then to find the last angle, you will subtract the 140° by 180°.

180°-140° = 40°

Hope this helped! :)

Answer:

 40

Step-by-step explanation:

First you add 70 and 70 together to get 140 then minus it by 180.

Then you will get 40 degrees as your answer.

Hope This Helps :)

792 groups

Step-by-step explanation:

5 people can be in a group. There's 12 people. So we can just use combination.

12C5. = 12 * 11 * 10 *9 * 8 = 792

Also, just post one question at a time. We aren't allowed to post multiple answers.

Five people can be in a group. There's 12 people. The combination will be 792 groups

Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.

The number of r-element combinations of n objects, with repetition is:

\(\overline{C}_{n,k} = \: ^{n + k-1}C_{k} = \dfrac{(n+k-1)!}{k! \times (n-1)!}\)

Thus, 5 people can be in a group. There's 12 people. So we can use combination.

12C5 = 12 * 11 * 10 *9 * 8

12C5 = 792

Five people can be in a group. There's 12 people. The combination will be 792 groups.

Answer for number 6: $8.10

Step-by-step explanation:

First of all, you start by multiplying 1.59 by 5. $1.59 x 5 = $7.95. Now, all you have to do is add $7.95 and $3.98. $7.95 + $3.98 = $11.90. Now the last this to do is Subtract $11.90 from $20.00. $20.00 - $11.90 = $8.10. You will receive $8.10 if he gives the cashier a $20.00 dollar bill.

Step-by-step explanation:

15.00_____100percent

18.60_____124 percent.

it increased witf 24 percent

Answer:

0.2% increase

First, you find the change between $15.50 and $18.60, which is 3.10. Then you do 3.10 divided by the original, which is 15.50. You should get 0.2.

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

All I did was count the lines on the coordinate grid between -12 and 6. I was counting by 2's because the grid itself is counting by 2's

========================================================

Explanation:

If you start at 6, and count the number of spaces to get to -12, you should count out 18 spaces.

Or you could start at -12 and move to 6 to move 18 spaces to the right. Keep in mind each tickmark represents 2 spaces.

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

You could also think of it like this:

Place point A at -12, B at 0, C at 6

The distance from A to B is 12 units. The distance from B to C is 6 units. In total we have AB+BC = 12+6 = 18 units from A to C.

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

Or you could use absolute value and subtraction

Let P = -12 and Q = 6

We could say

|P - Q| = |-12-6| = |-18| = 18

or

|Q - P| = |6 - (-12)| = |6 + 12| = |18| = 18

The order of subtraction doesn't matter as long as you apply absolute value. Absolute value represents distance from 0 on a number line, so absolute value is never negative.

Hello! :)

Answer:

\(\huge\boxed{751}\)

Let the smallest digit, or the units' digit, be equal to x:

Tens' digit is four more, therefore:

x + 4 represents the tens' digit.

Hundreds' digit is 2 more than the tens' digit, so:

2 + (x + 4), or x + 6 represents the hundred's digit.

These all sum up to 13, so write an expression to represent this:

x + (x + 4) + (x + 6) = 13

Combine like terms:

3x + 10 = 13

Subtract 10 from both sides:

3x = 3

Divide both sides by 3:

x = 1

Find the digits using the rules listed above:

Hundreds' digit: (1) + 6 = 7

Tenths' digit:  (1) + 4 = 5

Units' digit: 1 = 1

Therefore, the number is:

751.

Step-by-step explanation:Quadrant I and Quadrant IV

Two out of the four Quadrant planes have a positive x- value.

The coordinate axis split the plane into four parts called Quadrants or which can also be called Cartesian quadrants. These divided parts of the plane are numbered I, II, III, and IV.

The first quadrant/ quadrant I which lies on the upper axis on the right side of the plane has two positive quadrants, that is one positive x and one positive y because both of them lie in the positive direction of the axis.

The second quadrant/ quadrant II which appears on the upper right side of the plane has one positive and one negative coordinate that is, one positive y and one negative x because the x coordinate lie in the opposite direction of the sign of the numbers.

In quadrant III which lies in the downward direction and the left side of the plane has two negative coordinates both x and y. both the coordinates go towards the opposite direction of the sign convention.

in the last quadrant/ quadrant IV have a positive x- coordinate and one negative y-coordinate. Because the y coordinate goes against the positive sign convention.
