If the ratio of miles is
.. mr : mrs = 3 : 1
The total number of "ratio units" is 3+1 = 4, so each one stands for 3200/4 = 800 miles.

Mr Storey drove 3*800 = 2400 miles
Mrs Storey drove 1*800 = 800 miles

A square tile measures 16 inches on each side. If 1 inch = 2.54 centimeters, determine the area of the tile in square centimeter
garik1379 [7]

The answer to the nearest square centimeters is 1,652 cm2.

The calculation can be calculated as follows :

The first step is to convert the tile measures in inches to centimeters.

1 inch = 2.54 centimeters

16 inches = 16 x 2.54 centimeters

16 inches = 40.64 centimeters

The second step is to calculate the area of the tile in square centimeters.

Tile's area in square centimeters

= 40.64 x 40.64

= 1,651.6096 cm2

The last step is to round the answer to the nearest square centimeters.

= 1,651.6096 cm2

= 1,652 cm2

Hence, the area of the tile in square centimeters is 1,652 cm2.

Step-by-step explanation:

As we are talking time we work in mod 12.

9 mod12 + 111 mod12

The concession stand sells hot dogs and soda during the pee-wee football games.John bought 6 hot dogs and 4 sodas and paid $6.70
Eva8 [605]

Answer: Hotdog cost $0.75

Price of soda = $0.55

Step-by-step explanation:

Let the price of hot dogs be x.

Let the price of sodas be y.

6x + 4y = 6.70 ...... i

4x + 3y = 4.65 ....... ii

Multiply equation i by 4

Multiply equation ii by 6

24x + 16y = 26.80 ........ iii

24x + 18y = 27.90 ......... iv

Subtract iii from iv

2y = 1.10

y = 1.10/2

y = $0.55

Price of soda = $0.55

From equation i,

6x + 4y = 6.70

6x + 4(0.55) = 6.70

6x + 2.20 = 6.70

6x = 6.70 - 2.20

6x = 4.50

x = 4.50/6

x = $0.75

Hotdog cost $0.75

At Thanksgiving, Mrs. Jones overcooked the turkey so all but 5 of it had to be thrown away. The 8 people at dinner that
VashaNatasha [74]

<em>The question has inconsistent or incomplete data, so I'm filling the holes with key data.</em>

Answer:

<em>Every people at dinner received one-tenth of the original turkey= 0.1</em>

Step-by-step explanation:

<u>Proportions</u>

If some fraction a/b of a whole total M is to be computed and later removed, we proceed as follows

* Compute the portion to be removed as a/b*M

* Subtract it from the total quantity: M-a/b*M=M(1-a/b)

I'm assuming 1/5 of the turkey was lost due to overcooking. It means that (1-1/5) of the turkey remained for dinner, that is, 4/5 of the turkey.

Each people at dinner received the same amount of the remaining, so we must divide 4/5 by 8, to get 4/40, or 1/10. It means that every people at dinner received one-tenth of the original turkey
