The Davis family traveled to Silver Lake in five hours. Their return trip took StartFraction 7 Over 8 EndFraction of the time it took to travel to the lake. How long did the return trip take?

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

To find the answer, all we need to do is divide his additional profits ( $1,645 ) by the number of days he made the profit ( 7 days in the week )

$1,645 ÷ 7 = $235

Steven's Shop profits increased by $235 each day!

The total money Ani raised was  217 dollars.

Cost price of soda = 310 dollars

money raised = selling price - cost price

What is selling price?

The cost at which something is sold. Calculate the total cost of all the items you bought. To calculate the cost price, divide the total cost by the quantity of units purchased. Use the selling price formula to calculate the final price: Cost price plus profit margin equals selling price.

What is cost price ?

Cost price is the complete sum of money that a manufacturer must spend to create a specific good or render a specific service. Cost is equal to Selling price plus Loss ( when selling price and loss is given ) Cost price = 100 Selling Price + 100 + Profit (where the Selling Price and Profit Percentage are supplied)

Hence

x = 527 - 310

=217 dollars

x = -4

Step-by-step explanation:

3x + 4y = -16

X = 4y

3(4y) +4y = -16

=> 12y + 4y = -16

=> 16y = -16

=> y = -1

3x + 4(-1) = -16

Step-by-step explanation:

Given the ratio 7 : 5

The 42 iPhones sold relates to the 7 part of the ratio.

Divide 42 by 7 to find the value of one part of the ratio.

42 ÷ 7 = 6 ← value of 1 part of the ratio, thus

5 parts = 5 × 6 = 30 ← number of Samsung phones sold

Answer:

Step-by-step explanation

A = (3.14)(r^2)

A = 3.14 x 182.25 = 572.265 unit sq.

-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.

Answer:

500 ft

Step-by-step explanation:

use this formula

The actual distance between first and second ride is 500 ft.

The distance between two point P(a, b) and Q(c, d).

so, the distance PQ = √(c-a)² + (d- b)²

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

Using the distance formula

d =  √( 3-0)² + (0-4)²

d = √9+ 16

d= √25

d = 5 units

So, the distance between first ride and second ride in the map is 5 units.

and,1 units  = 100 ft

5 units = 500 ft

Hence, the actual distance between first and second ride is 500 ft.

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

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
