Could a triangle have angle measures of 94°, 106°, and 11° EXPLAIN HOW YOU KNOW.​

Answers

Answer:

Nope

Step-by-step explanation:

All angles have to measure up to where adding up two of any angles will result in a number greater than or equal to the angle that was not added.

But here if we add up 94° and 11°, we end up with 105°.

Since 105° is lower than the angle not added, which is 106°, this triangle cannot exist.

A store is instructed by corporate headquarters to put a markup of ​67% on all items. An item costing ​12$ is displayed by the store manager at a selling price of ​8$. As an​ employee, you notice that this selling price is incorrect. Find the correct selling price. What was the​ manager's likely​ error?

please help me in really stuck you would be a huge help

Answers

Answer:

Step-by-step explanation:

12$ = original price (need to add 67% mark up)

12/100 = 0.12 = 1%

0.12 x 67 = $8.04 markup

12 + 8.04 = $20.04 is the correct selling price

the error was accidently not adding the markup ($8.04) to the original price

Seventeen lines drawn in a plane, with no three concurrent and no two parallel, divide the plane into
closed regions (bounded on all sides) and open regions. The number of closed regions is

Answers

Answer:

120

Step-by-step explanation:

Make a chart:

Lines:                  0   1    2   3  4   5   6

Closed regions: 0   0   0   1   3   6   10

Find the number of numbers using the formula:

[tex]\frac{first term + last term}{2}[/tex] x 14 = [tex]\frac{2 + 15}{2}[/tex] x 14

                                  = 8.5 x 14

                                  = 119

119 + 1 = 120

(add 1 because we didn't count the first line in the formula)

I hope this helps :)

The total number of closed regions is 120.

Given that,

Seventeen lines are drawn in a plane, with no three concurrent and no two parallel, dividing the plane into closed regions (bounded on all sides) and open regions.

Used the formula to calculate the number of closed regions with n sides is,

Number of sides = (n - 1) (n - 2) / 2

Here, n = 17

Hence, The number of closed regions is,

Number of sides = (n - 1) (n - 2) / 2

Number of sides = (17 - 1) (17 - 2) / 2

Number of sides = 16 × 15 / 2

Number of sides = 120

Step-by-step explanation:

You can use the order of operations to evaluate the expression. Perform the subtraction inside the parentheses: two minus three equals negative one. Evaluate the exponents: two to the sixth power is sixty-four. Multiply and divide in order from left to right: Twelve point six times negative one equals negative twelve point six, and sixty-four divided by four is sixteen. Add and subtract in order from left to right: Negative twelve point six plus sixteen equals three point four.

9/20 - 7/15=
help guys plsss need na now .,.

Answers

Answer:

-1/60

Step-by-step explanation:

9/20-7/15=27/60-28/60

=-1/60

Answer:

-1/60

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(9/20, 7/15) = 60

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(9/20×33)−(7/15×44)

Complete the multiplication and the equation becomes

27/60−28/60

The two fractions now have like denominators so you can subtract the numerators.

Then:

27−28/60=−1/60

This fraction cannot be reduced.

Therefore:

9/20−7/15=−1/60
