Calculate the following total weekly wages:a) 38 hours at $22.10 per hour, plus 2 hours at time-and-a-half
b) 37 hours at $18.32 per hour, plus 3 hours at time-and-a-half and 2 hours at double time

Answers

Answer 1
Answer: So we would multiply 22.10 times 38, which is $839.00, then multiply 22.10 times the two extra hours which is $44.20, and then you'll divide 22.10 in half to find out how much it would be in a HALF hour, which is $11.05, and add all of those answers and your final answer for A. would be $894.25.

We would do the same as above for B., but only 2 hours at double would be 4 hours, and your final answer would be $815.24.

I hope I helped! =D

A bag contains 2 red, 4 yellow, and 6 blue marbles.Two marbles are drawn at random. Find the portability that both are blue.

Answers

If two marbles are drawn at random, the probability that they are both blue is 1/4

The formula for calculating the probability is given as:

Probability = Expected outcome/Total outcome

  • Given that a bag contains 2 red, 4 yellow, and 6 blue marbles

  • Total outcome = 2 + 4 + 6 = 12 marbles

Since we are to find a probability of picking 2 blue balls

Pr(2 blue balls) = 6/12 * 6/12

Pr(2 blue balls) = 1/2 * 1/2

Pr(2 blue balls) = 1/4

Hence if two marbles are drawn at random, the probability that they are both blue is 1/4

Total number of marbles is 12, there are 6 blues.
When picking the first one the probability to pick the right one is (6)/(12)=(1)/(2)
When we pick the second one there are 11 marbles and only 5 blue so the probabilty is (5)/(11)

We need to pick 2 blues one after another so we multiply probabilities (1)/(2)*(5)/(11)=5/22=0.227 The probability is around 23%

The medicine capsule consists of a cylinder with a hemisphere at each end. The total length of the capsule is 18 millimeters. The diameter is 7 millimeters. Which choice is the best approximation of the total surface area of the capsule? Use 3.14 to approximate pi. possible answers a)396 square millimeters b)550 square millimeters c)1,407 square millimeters d)1,099 square millimeters

Answers

Given: 
diameter: 7 mm
total length = 18 mm

There are two shapes in this problem.
1) a sphere
2) a rectangle shaped cylinder

We need to get the area of both shapes to have the best approximation of the total surface area of the capsule.

Area of a sphere = 4 π r² = 4 * 3.14 * (3.5mm)² = 12.56 * 12.25mm²
Area of a sphere = 153.86 mm²

Area of a rectangle = length * width 
*in this case, we need to compute for the circumference of the circle to get the measure of the width

Area of a rectangle = (18-7mm) * 7 * 3.14
Area of a rectangle = 11mm * 7mm * 3.14
Area of a rectagnle = 241.78 mm²

Total surface area = 153.86 mm² + 241.78 mm² = 395.64 mm² 

Choice A.) 396 square millimeters.

17x - 6 + 3x - 5 = x + 11 + 4x

Answers

17x - 6 + 3x - 5 = x + 11 + 4x

The first thing to do is to get all the xs on the same side. 

17x + 3x - x - 4x = 11 + 5 + 6
15x = 22
x = 22/15

The answer is x = 22/15 

22 - 15 = 7
If this needs to be simplified, the answer is x = 1 7/15
17x - 6 + 3x - 5 = x + 11 + 4x
17x-11+3x=x+11+4x
20x-11=x+11+4x
20x-11=5x+11
Subtract 5x
20x-11-5x=11
15x-11=11
Add 11
15x=11+11
15x=22
Divide by 15
x= (22)/(15)
x=1 (7)/(15)

A book shows an enlarged photo of a carpenter bee. A carpenter bee is about 6×10^-3 m long. The photo is 13.5 cm long. About how many times as long as a carpenter bee is the photo?

Answers

 A ratio compares values. A ratio says how much of one thing there is compared to another thing. We do as follows:

length of photo/ length of a carpenter bee = ratio of the two
13.5 / 6x10^-3 = 2250

Therefore, the photo is 2250 longer than the carpenter bee.
