6 0

Answer:

a = 5

Step-by-step explanation:

Since the triangle is right use the sine ratio to solve for a and

sin30° = \frac{1}{2}, thus

sin30° = \frac{opposite}{hypotenuse} = \frac{a}{10}, hence

\frac{a}{10} = \frac{1}{2} ( cross- multiply )

2a = 10 ( divide both sides by 2 )

a = 5

A projectile is fired at 571 mi hr. How fast is that in meters per second to the nearest whole value? Use the conversion factor
ELEN [110]

Answer:

Consider this: factors that are the same that are in the numerator and denominator of a fraction cancel out.

e.g. 20/30 = [2(10)]/[3(10)] = 2/3      This is because the 10 present in the numerator exactly equals the 10 present in the denominator.

We can use the above principle for these types of problems!

If the projectile is fired at 422 mi/hr, and we want to convert this speed into m/s, we just need to go through the following process:

422 mi/hr * 1610m/1mi * 1hr/60min * 1min/60s = 189 m/s

MrRa [10]

Answer:

5 meters

Step-by-step explanation:

So Zane starts at -25 meters, then, after 35 seconds, he makes it to the top. The questions is asking how high he climbed every 7 seconds. As we know, 7x5 is equal to 35. this means that we can divide 35 and 25 by 5 to get the answer. 25/5 is equal to 5, so that means he climbed 5 meters every 7 seconds. I hope this helps!

cricket20 [7]
The fact that it can turn its head 180 degrees is just extra information. They tell us that it is 10.5 cm long. What they're asking for is the length in a mixed number, so 10.5 as a mixed number.
