Jim works as a manager at Food Lion. He earns $600.00 a week in salary. If Jim has three paid vacation weeks a year… what is Jim’s gross salary a year?

Answers

Answer:

Step-by-step explanation:

Jim' s salary will be

600*52=31,200

his vacation is paid, so it doesn't matter how many weeks he has off.

Answer:

$31,200.00 gross pay

Step-by-step explanation:

$600.00 he makes every week times the 52 weeks of the year since he gets paid vacation weeks.

52 weeks x $600.00 = $31,200.00 in gross pay

In triangle ABC, the measure of angle CAB is 80° and the measure of angle ABC is 45.5°. What is the measure of angle BCA in degrees? A 125.5°125.5 degrees B 54.5°54.5 degrees C 55.5°55.5 degrees D 64.5°

Answers

Answer:

B 54.5°

Step-by-step explanation:

Since we have a triangle,

CAB + ABC + BCA = 180 (sum of angles in a triangle)

Since CAB = 80° and ABC = 45.5°, substituting these into the equation, we have

80° + 45.5° + BCA = 180°

simplifying, we have

125.5° + BCA = 180°

collecting like terms, we have

BCA = 180° - 125.5°

BCA = 54.5°

So, the answer is B

Answer: 30, 15 cm

Step-by-step explanation:

Given

The length of the rectangle is twice its breadth

The area of the rectangle is [tex]450\ cm^2[/tex]

Suppose the breadth is x

So, the length is 2x

The area can be written as

3x+30=180 degrees, what is the value of the letter x in this problem?

Answers

Answer:

50

Step-by-step explanation:

180-30=150/3=50

3x + 30 = 180

     -30     -30     subtract 30 on both sides, solve for 180 - 30 which is 150.

___________

3x = 150

__    ___       divide 3 on both sides, solve for 150 ÷ 3 which is 50.

The Answer is : 20.15
Theres an easier way. Pythagorean theorem-
A^2+B^2=C^2
A and B are legs while C is the hypotenuse or slanted one.

Dairy Queen Restaurant charges $4.00 for a Mini-Blizzard (a type of ice cream treat) and $0.50 per additional candy topping that the customer wishes to mix-in. You determine that a linear model is a good way to represent this information. A. What is the rate of change (slope, m, with units): __A___ ____ B. What is the y-intercept: __B___ ____ C. Create a linear model in y = mx + b form for this situation:

Answers

Answer:

Slope = $4.00

y - intercept = $0.50

y = 4x + 0.5

Step-by-step explanation:

Given :

Cost of Mini blizzard = $4.00

Cost of optional or additional topping = $0.50

A linear model is in the form:

y = mx + b

For this scenario

y = total cost of order

m = slope Coefficient = cost of mini blizzard

x = number of mini blizzards ordered

c = additional cost, cost of candy topping

Hence, rate of change, slope, m = cost of mini blizzard = $4.00

The y - intercept = cost of candy topping = $0.50
