On one particular day, Jamal arrived late to find four other co-workers waiting for him to arrive. They were unable to do other work because they had made arrangements to have their position covered and to work with Jamal on a special project. Nothing could be done until he got there. The other workers earned wages as followed: Derek earns $10.00/hr; Sam earns $11.80/hr; Penny earns $11.00/hr and Zachary earns $13.00/hr. How much was lost in unproductive wages because Jamal arrived 15 minutes late?

Answers

Answer: $11.45

Step-by-step explanation:

Arriving 15minutes late simply means 15/60 = 1/4 of the wages has been lost. We then multiply 1/4 by each person's wage. This will be:

Derek = 1/4 × $10.00

= $2.50

Sam = 1/4 × $11.80

= $2.95

Penny = 1/4 × $11.00

= $2.75

Zachary = 1/4 × $13.00

= $3.25

The amount lost will be:

= $2.50 + $2.95 + $2.75 + $3.25

= $11.45

Answers

Answer:

v = -5

Step-by-step explanation:

to get v by itself, you must subtract 3 from both sides, not only to cancel out the positive 3 but to keep both sides equal. this leads to -5 = v so that's your answer.

Answer:

Your answer is: [tex]V= -5[/tex]

X = 70

Explanation: in an isosceles triangle the two bases equal each other

Equation set up - 2x + 2x + 40 = 180

Step-by-step explanation:

PQR = PRQ = 2x ° ( base angle of an isosceles are equal ) .

therefore

PQR + PRQ + QPR = 180° ( sum of angles in a triangle )

2x + 2x + 40 = 180

4x + 40 = 180

subtract 40 from both sides

4x = 140

divide through by 4

x = 35°

5y = -3x + 7

Parallel = same slope
y = -3/5x + b

y = -3/5x + 18/5
-3/5x - y = -18/5

Step-by-step explanation:

Lateral area of a cone is represented by,

Lateral surface area = πrl

Here 'r' = Radius of the circular base

l = lateral height of the cone

By this formula,

Lateral area = π(12)(15)

                    = 565.49

                    ≈ 565.5 square inch

Therefore, 565.5 in² is the answer.

[tex]x=3\sqrt{2}\\[/tex]

Step-by-step explanation:

Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.

This means the length of the side to the left is also x as shown in the image below.

The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:

[tex]x^2+x^2=6^2[/tex]

Operating:

[tex]2x^2=36[/tex]

[tex]x^2=18[/tex]

Since 18=9*2

[tex]x=\sqrt{9*2}[/tex]

[tex]\mathbf{x=3\sqrt{2}}[/tex]

K is between J and L. JK = 3x – 5, and KL = 2x + 1. IfJL = 16, what is JK?
A. 7
B. 8
C. 9
D. 13

Answers

Answer:

If JL = 16, we will get JK = 7

Option A is correct option.

Step-by-step explanation:

We are given:

K is between J and L

JK = 3x – 5, and KL = 2x + 1.

IfJL = 16, what is JK

We know that K is between J and L it means it divides JL into JK and KL equally or we can say that adding JK and KL we can get JL

So, We can write:

[tex]JL = JK + KL\\16=3x-5+2x+1[/tex]

Solving the expression we can find first value of x and then value of JK

[tex]16=3x-5+2x+1\\16=5x-4\\16+4=5x\\20=5x\\x=\frac{20}{5}\\x=4[/tex]

So, we get x = 4

Now, put the value of x in JK=3x-5 to get value of JK

[tex]JK = 3x-5\\JK=3(4)-5\\JK = 12-5\\JK=7[/tex]

So, if JL = 16, we will get JK = 7

Option A is correct option.

Name the additive identity of (-10+4i)

Answers

An additive identity for i, denoted e, is an element in i such that for any element i in i, e + i = i = i + e. Example: The formula is i + 0 = i = 0 + i.

The additive identity of (-10+4i) is (0+0i).

What is additive identity?

Additive identity property states that when a number is added to zero will give the same number in result . “Zero” is called the identity element, If we add any complex number with zero, the resulting number will be the same complex number. It doesn't change the number and keeps its identity.

For the given situation,

The complex number is (-10+4i)

The general form of complex number is a+bi. The additive identity for complex number is 0+0i.

⇒ [tex](-10+4i)+(0+0i)=(-10+4i)[/tex]

Hence we can conclude that (0+0i) is the additive identity of (-10+4i).

Dylan has a bank that sorts coins as they are dropped into it. A panel on the front displays the total number of coins inside as well as the total value of these coins. The panel shows 90 coins with a value of $17.55 inside of the bank. Dylan only collects dimes and quarters. Determine how many quarters and how many dimes Dylan has.

Answers

Answer: There are 57 quarters and 33 dimes.

Step-by-step explanation:

let x = Number of quarters

y= Number of dimes

As per given , we have

x+y = 90  (i)

0.25x+0.10y= 17.55  (ii)

Multiply 10 on both sides of (ii)

2.5x+y= 175.5    (iii)

Eliminate (i) from (iii) , we get

1.5x = 85.5

⇒ x= 57

Put value of x in (i) , we get

57+y=90

⇒  y= 90-57

⇒  y= 33

Hence, there are 57 quarters and 33 dimes.
