Answer:

They travel for 3.4 hours before they meet.

Step-by-step explanation:

Given that:

Distance between the cities = 374 miles

Speed of Car 1 = 50 mph

Speed of Car 2 = 60 mph

As the cars are moving towards each other,

Combined speed = 50 + 60 = 110 mph

We know that:

Distance = Speed * Time

374 = 110 * Time

Time = $\frac{374}{110}$

Time = 3.4 hours

Hence,

They travel for 3.4 hours before they meet.

A gem is cut in a kite shape. It is 6.2 millimeters wide at its widest point & 5 millimeters long. What is the area?

arlik [135]

Answer: $15.5\ mm^2$

Step-by-step explanation:

You can calculate the area of a kite with the following formula:

$A=\frac{d_1d_2 }{2}$

Where $d_1$ is the length of a diagonal and $d_2$ is the length of the other diagonal.

In this case, you can identify that:

$d_1=6.2\ mm\\d_2=5\ mm$

Therefore, the final step is to substitute the values into the formula.

Then, the area is:

$A=\frac{(6.2\ mm)(5\ mm)}{2}\\\\A=15.5\ mm^2$

In an average year, the American chemical industry produces more than 9.5 million metric tons of sodium carbonate. Over half of

Phoenix [80]

Answer:

2.09 × 10¹⁰ pounds

Step-by-step explanation:

The American chemical industry produces more than 9.5 million metric tons of sodium carbonate.

in this problem we have to calculate the amount in pounds of sodium carbonate are produced annually.

so we will convert the amount of 9.5 million metric tons to pounds.

Since in 1 metric ton = 2204.62 pounds

Hence, 9,500,000 metric ton = 2204.62 × 9,500,000

= 20943890000 pounds

= 2.09 × 10¹⁰ pounds

2.09 × 10¹⁰ pounds of sodium carbonate are produced annually.

Answer:

$V_{cone} =65.94\: cm^3$

Step-by-step explanation:

Height of cone (h) = 7 cm

Base radius (r) = 3 cm

Formula for Volume of cone is given as:

$V_{cone} = \frac{1}{3}\pi r^2h$

Plugging the values of h and r in the above formula, we find:

$V_{cone} = \frac{1}{3}(3.14) (3)^2(7)$

$\implies V_{cone} = \frac{1}{\cancel 3}(3.14) (\cancel 9)(7)$

$\implies V_{cone} = (3.14) (3)(7)$

$\implies V_{cone} =65.94\: cm^3$
