Enrique is driving to texas. he travels at 70 kilometers per hour for 2 hours, and 63 kilometers per hour for 5 hours. over the

To solve this problem, we know that the formula for average speed is:

average speed = total distance travelled / total time

Now let us first calculate for the total distance travelled. Calculating:

total distance travelled = (70 km / hr) * 2 hr + (63 km / hr) * 5 hr

total distance travelled = 140 km + 315 km

total distance travelled = 455 km

Now for the total time:

total time = 2 hours + 5 hours

total time = 7 hours

Hence, the average speed is therefore:

average speed = 455 km / 7 hours

<span>average speed = 65 km / hr</span>

Jim sold 396 tickets for the school play. Student tickets cost $3 and adult tickets cost $4. Jim's sales totaled $1385. How many

Tamiku [17]

Let student tickets be s and adult tickets be a. The number of tickets sold of both adult and student then is s + a = 396. If each student ticket costs $3, then we represent the money equation by tacking the dollar amount onto the ticket. 3s is the cost of one student ticket. 4a is the cost of an adult ticket. The total money from the sales of both is 4a + 3s = 1385. We now have a system of equations we can solve for a and s. If s+a=396, then s = 396-a. We will sub that into the second equation to get 4a + 3(396-a) = 1385. Distributing we have 4a+1188-3a=1385. a = 197. That means there were 197 adult tickets sold. If s + a = 396, then s + 197 = 396 and s = 199. 197 adult tickets and 199 student tickets. There you go!

The weight of gemstones, such as diamonds, rubies, and emeralds, is measured in carats. A carat is a unit of measure equal to 20

Alexxx [7]

We are told in the question that 1 carat is equal to 200 mg.

The Hope Diamond is 44.5 carats. Let's multiply the weight of 1 carat by 44.5 to get the weight of the Hope Diamond in mg:

$\frac{200mg}{1 carat}* \frac{44.5 carats}{1}=8,900 mg$

The total weight of the Hope Diamond is 8,900 mg. However the question asks for the weight in grams. There are 1000 mg in 1 gram, so let's divide the known weight of the Hope Diamond in mg by 1000 to get the weight converted to grams:

$\frac{8,900mg}{1000}=8.9grams$

Now we know that the weight of the Hope Diamond is equal to 8.9 grams.
