The driving distance from Chicago to San Francisco is 2,142 miles. The Hathaway family left Chicago on Monday morning, December

Mekhanik [1.2K]

Answer:

They arrive on Monday, December 13th

Step-by-step explanation:

First, we know that this family must drive a total of 2,142 miles.

They average 50 miles per hour and drive 6 hours each day, thus we can see that they drive (50)(6)=300 miles per day.

Now, to know how many days it will take them to drive the total of 2,142 miles we are going to divide the total amount of miles between the number of miles driven per day:

2,142÷300= 7.14

Thus, it takes them 7.14 days to drive 2,142 miles.

If we round this (since the number is greater than 7 this would mean it takes them more than 7 days and they would stop at 7 for the day) to the next digit, we would have that it will take them 8 days to get to San Francisco.

Thus, since they start on December 6th (day 1), December 7th would be day 2 and following this pattern we would have that the eighth day would be December 13th.

Now, since the days repeat every 7 days and we now that December 6th was monday, we would have that the day they arrive to San Francisco (December 13th) is monday too.

The distance between the Sun and the Earth is 1 .496 x 1O^8km and distance between the Earth and lhe Moon is 3.84 x 10^8m. Durin

Dennis_Churaev [7]

Answer:

1.49216*10^8 km

Step-by-step explanation:

The first thing is to pass all the distances to the same unit system, since the distance from the earth to the sun is in kilometers and from the earth to the moon is in meters, therefore we will pass the distance of the moon in kilometers:

3.84 x 10 ^ 8m * 1 km / 1000 m = 3.84 x 10 ^ 5 km

To calculate the distance between the moon and the sun, it would be the difference between the distance they give us in the statement, because they have a point in common which is the earth, it would be:

1.496 x 10 ^ 8 km - 3.84 x 10 ^ 5 km = 149216000 = 1.49216 * 10 ^ 8 km

Therefore the distance between the moon and the sun is 1,49216 * 10 ^ 8 km

Can someone help me for question 18 pls? I really need help to solve this question!!

Plug the x-values from the table into the given equation and solve for y.

y = 5 - x²

First column

replace x with -2

y = 5 - (-2)²

= 5 - (4)

= 1

(x, y) = (-2, 1)

Second column

replace x with -1

y = 5 - (-1)²

= 5 - (1)

= 4

(x, y) = (-1, 4)

Third column

replace x with 0

y = 5 - (0)²

= 5 - (0)

= 5

(x, y) = (0, 5)

Fourth column

replace x with 1

y = 5 - (1)²

= 5 - (1)

= 4

(x, y) = (1, 4)

Fifth column

replace x with 2

y = 5 - (2)²

= 5 - (4)

= 1

(x, y) = (2, 1)

Jordan's recipe calls for 3 cups of flour and 2 cups of water. what is the ratio of flour to water? if jordan wants to triple hi

allochka39001 [22]

You would multiply the cups of flour by 3 and the cups of water by 3. which would give you 9 cups of flour and 6 cups of water. the ratio is 1.5 cups of flour to 1 cup of water.
