Convert 10 miles per hour to meters per second. Round to the nearest tenth.

LUCKY_DIMON [66]

Answer:

4.5 meters/second

Step-by-step explanation:

First we can find out how to convert one hour into seconds, which will be 3600 seconds. Now we have to figure out how many meters are in a mile, and multiply that by 10 to figure out how many meters are traveled per 3600 seconds (hour). The amount of meters in a mile is about 1609.34, which means the number of meters in 10 miles is 16093.4 meters. Now we know that 10 miles per hour is equal to 16093.4 meters per 3600 seconds. The last thing we need to do is divide the amount of meters per 3600 seconds by 3600 to find the amount of meters traveled in one second. This means we have to do 16093.4/3600 which is about 4.47, which rounded to the nearest tenth is 4.5.

Find the area of the trapezoid below.

Pani-rosa [81]

Answer: 54 cm²

Step-by-step explanation: In this problem, we're asked to find the area of the trapezoid shown. A trapezoid is a quadrilateral with one pair of parallel sides.

The formula for the area of a trapezoid is shown below.

$Area =\frac{1}{2} (^{b} 1 + ^{b}2)h$

The <em>b's</em> represent the bases which are the parallel sides and <em>h</em> is the height.

So in the trapezoid shown, the bases are 6 cm and 12 cm and the height is 6 cm. Plugging this information into the formula, we have $\frac{1}{2} (6 cm +12cm)(6 cm)$ .

Next, the order of operations tell us that we must simplify inside the parentheses first. 6 cm + 12 cm is 18 cm and we have $\frac{1}{2}(18 cm)(6 cm)$ .

$\frac{1}{2} (18 cm)$ is 9 cm and we have 9 cm · 6 cm of 54 cm²

So the area of the trapezoid shown is 54 cm².
