What is the product of -3 1/4 aND -1 1/2
Soloha48 [4]

Answer:

Step-by-step explanation:

<u>"The product"</u> means multiplication so we have to multiply these two values together.

When we multiply two negative numbers together <u>it results in a positive</u>.

Keeping this in mind, solve the equation.

-3 1/4*-1 1/2

First multiply the fractions

1*1=1

4*2=8

1/8

Now the numbers.

-3*-1=3

The answer is 3 1/8.

Hope this helps!

Two planes, A and B, start from the same place and move in different directions, making an angle of 50º between them. The speed
cluponka [151]

Answer: The distance between them is 230.65 miles.

Step-by-step explanation:

Since we have given that

Speed of plane A (b) = 200 miles per hour

Speed of plane B (c) = 300 miles per hour

Angle between them = 50°

So,

We will use the "Cosine formula", we get

a^2=b^2+c^2-2bc\cos A\\\\a^2=200^2+300^2-2\times 200\times 300\cos 50\textdegree\\\\a^2=40000+90000-120000\cos 50\textdegree\\\\a^2=130000-120000\times 0.64\\\\a^2=130000-76800\\\\a^2=53200\\\\a=\sqrt{53200}\\\\a=230.65\ miles\ per\ hour

So, distance between the two planes after one hour will be

Distance=\frac{Speed}{time}=\frac{230.65}{1}=230.65\ miles

So, the distance between them is 230.65 miles.
