Answer:

7√2

Step-by-step explanation:

From the diagram given;

Hypotenuse = x

Opposite = 7

Angle = 45 degrees

According to SOH CAH TOA identity

Sin theta = opposite/hypotenuse

Sin 45 = 7/x

x = 7/sin45

x = 7/1/√2

x = 7 * √2/1

x = 7√2

Hence the value of x is 7√2

What is r/15 &gt; -3
Sever21 [200]
I'm gonna do this 2 ways because I'm not sure what you mean about the line. I'm going to indicate greater than or equal to with >=.

1st I'll solve for

r/15 >= -3

multiply by 15 on each side

r >= -45

Next I'll solve for

r/15 >= 3
multiply 15 on each side

r >= 45

So depending on if that is a 3 or -3 that is how you would do it....

So did I read the problem right?

Two trucks are traveling in the same direction, one going twice as fast as the other. At the end of 6 hours they are 204 miles a
TEA [102]

Answer:

34 mph and 68 mph respectively

Step-by-step explanation:

Step one:

given data

let the speed of the first truck be x mph

and the speed of the second truck be 2x mph

time taken = 6 hours

total distance = 204 miles

Step two:

from speed = distance/time

distance= speed*time

hence

2x*6-6x= 204

12x+6x= 204

6x= 204

divide both side by 6

x= 204/6

x=34 mph

The second truck was moving at

=2x

=2*34

=68 mph
