Team Z can do the work in 26 days, and working together Team Z and Y can do the same work in 14 days. How many days would it take for Y alone to do the work? Round your answer to the nearest whole number.

Answers

Answer:

30 days

Step-by-step explanation:

The above question is solved as shown below:

Working together Team Z and Y can do the same work in 14 days.

1/Team Y + 1/Team Z = 1/14 days

Team Z can do the work in 26 days,

Hence:

1/Team Y + 1/26 days = 1 /14 days

= 1/ Team Y + 1/26 = 1/14

1/Team Y = 1/14 - 1/26

The Lowest Common Denominator = 182

Hence:

1/Team Y = 13 - 7/182

1/Team Y = 6/182

Cross Multiply

Team Y × 6 = 1 × 182

Team Y = 182/6

Team Y = 30.33 days

Approximately to the nearest whole number = 30 days

Therefore, Team Y alone can do the job in 30 days

The Outdoor Furniture Center buys wooden benches for $50 each. The owner of the Outdoor Furniture Center sells the benches for a 120% markup. At the end of the season, the owner wants to sells all the benches that are in stock. He sells the benches for 20% off.

What is the total price of a bench with the 20% discount plus a 5% sales tax?

Practice
Show your work

Answers

Answer:

92.4

Step-by-step explanation:

50$ + 120% = 110

110 - 20% = 88

88 + 5% = 92.4

The total price of a bench with the 20% discount plus a 5% sales tax is $92.4.

What is Markup Percentage?

Markup percentage is defined as the total profit of the commodity in terms of percentage. It is calculated by dividing the difference of the selling price and the cost with the cost and then multiply to 100.

Markup Percentage = [(sales price - cost) / cost] × 100

Cost of a bench = $50

There is 120% markup in the bench

Selling price = $50 + ($50 × 120%)

                     = $50 + ($50 × 1.2)

                     = $50 + $60

                     = $110

At the end of the season, owner gives 20% discount.

Price of the bench after 20% discount = $110 - (20% × 110)

                                                                = $110 - (0.2 × 110)

                                                                = $110 - $22

                                                                = $88

There is a sales tax of 5%.

Last selling price of the bench = $88 + (5% × $88)

                                                   = $88 + (0.05 × $88)

                                                   = $88 + $4.4

                                                   = $92.4

Hence, the owner sells the bench at the season at $92.4.

Answer:

The identity property of addition

Step-by-step explanation:

Jamal uses the steps below to solve the equation 6x – 4 = 8.

Step 1: 6x – 4 + 4 = 8 + 4( Addition step of equality)

Step 2: 6x + 0 = 12

Step 3: 6x = 12 (Identity property of Addition)

Step 4: StartFraction 6 x Over 6 EndFraction = StartFraction 12 Over 6 EndFraction

Step 5: 1x = 2

Step 6: x = 2

The value of 3centimeters to kilometers is 0,00003 km

Converting centimeters to meters

In order to convert centimeters to kilometers, we will use the conversion factor below.

100cm = 1m

1000m = 1km

Given 3cm

3cm = 3/100 m

3cm = 0.03m

Convert to km

Since 1000m = 1km

0.03m = 0.03/1000

0.03m = 0.00003km

Therefore the value of 3centimeters to kilometers is 0,00003 km

4. Which of the following differences could not give a distance between two points on a number line? Explain why. a. 19-7 c. -12-(-7) b. -3 - (-18) d. 14-(-6)​

Answers

-12 -(-7) could not be a distance.

Distance:

Distance traveled is the total length of the path traveled between two positions. It can either be a 0 or a positive number that's mean it can never be a negative number.

So from the above-given statement we have

a) 19-7 = 12 (which is positive number)

b) -12 - (-7) = -12 + 7 = -5 ( which is a negative number)

c) -3-(-18) = -3 + 18 = 15 ( which is a positive number)

d) 14-(-6) = 14 + 6 = 20 ( which is a positive number)

Therefore option b i.e., -12 - (-7) cannot be a distance between two points on a number line.

The line AB and the segments AC and BC form triangle ∆ABC, which gives the measure of m‹2 + m‹3 as following option;

C. 90°; m‹1 + m‹2 + m‹3 = 180°. m‹1 = 90°, so m‹2 + m‹3 = 90°

How can m‹2 + m‹3 in ∆ABC be calculated?

From the given descriptions, we have;

Lines AB and CD are horizontal lines.

Segment that extends from A to C which is segment AC is a vertical line

Therefore;

m‹BAC = m‹1 = 90°

‹BAC, ‹ABC, and ‹ACB, which are angles 1, 2, and 3 are interior angles of ∆ABC

Which gives;

m‹1 + m‹2 + m‹3 = 180° (sum of interior angles of a triangle theorem)

Therefore;

90° + m‹2 + m‹3 = 180° (substitution property)

m‹2 + m‹3 = 180° - 90° = 90°

m‹2 + m‹3 = 90°

The correct option is therefore;

C. 90°; m‹1 + m‹2 + m‹3 = 180°. m‹1 = 90°, so m‹2 + m‹3 = 90°
