Answer:

Sum angle of triangle BHD = 180°

36 + 39 + BHD = 180

BHD = 180 - 36 - 39

= 105°

BHD + x° = 180° (straight angle)

105° + x° = 180°

x = 180 - 105

= 75°

Your lunch in the hospital cafeteria cost $6.50. Based on working 50 weeks per year, how much will you spend on lunch per year?

The total amount spent on lunch per year would be 325 dollars.

<h3>What is the fundamental principle of multiplication?</h3>

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given that Your lunch in the hospital cafeteria cost $6.50. Based on working 50 weeks per year, then;

The lunch in the hospital cafeteria cost = $6.50.

The total amount spend on lunch per year;

6.50 x 50

325

Hence, the total amount spent on lunch per year would be 325 dollars.

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

Nikitich [7]

Answer:

Last week her sales were <u>$4500</u>.

Step-by-step explanation:

Given:

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.

She also earns a base salary of $750 per week.

Her total earnings for the week were $1,076.25.

Now, to find her sales last week.

Let the sales of last week be $x.$

Base salary = $750.

Total earnings = $1076.25.

So, we deduct the base salary from the total earnings first:

$1076.25-750$

$=326.25.$

Thus, the rest of the earnings is $326.25 which is the 7.25% commission on sales.

Now, to get the sales of last week we put an equation:

$7.25\%\ of\ x=326.25$

$\frac{7.25}{100} \times x=326.25$

$\frac{7.25x}{100} =326.25$

<em>Multiplying both sides by 100 we get:</em>

$7.25x=32625$

<em>Dividing both sides by 7.25 we get:</em>

$x=4500.$

The sales of last week = $4500.

Therefore, last week her sales were $4500.

PLEASE HELP ME!!!

Rashid [163]

Step-by-step explanation:

We need to find the value of angle D so that we can solve for X. To do that we need to find the value of angle A and that value will be the same value as D because these angles are the same.

To do that we have to add angles C and B together and that equals 118°. Then we have to realize that all the angles of a triangle add up to 180°. So then we have to subtract 118° from 180° and that equals 62°. So now we have the value of A.

If the value of angle A is 62° then that must be the value of angle D because these two angles are the same. So now that we have the value of angle D we need to solve for X. This equation is asking what times 2 equals the value of X. We know the value of X is 62°. So what times 2 equals 62°?

31×2=62°

Therefore the value of X is 31

Hope this helps! If you have any more questions or you need further clarification please comment down below or message me! Good luck!

Answer:

x = 54°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

The pentagon here has 5 sides, thus

sum = 180° × 3 = 540°

Each interior angle = 540° ÷ 5 = 108°

x is one half of the interior angle, thus

x = 0.5 × 108° = 54°
