2x+x=105
3x=105
The answer is A
We get all these to have the same denominators for all the fractions.
2*2/9*2 = 4/18
1*2/9*2 = 2/18
1*3/6*3 = 3/18
Now we can add all the numerators.
4/18 + 2/18 + 3/18 = 9/18
Simplify our answer by dividing both numbers by 3, then by 2.
9/3 and 18/3 = 3/6= 1/2
Our final answer is 1/2
Answer:
x = 62 degrees
Step-by-step explanation:
Since this is a right angle, we can use trig functions
cos theta = adjacent/ hypotenuse
cos x = 3.7/7.9
Taking the inverse cos of each side
cos ^ -1 ( cos x) = cos ^-1 (3.7/7.9)
x =62.07246803
To the nearest degree
x = 62 degrees
Well we know she filled up her car 11 times each with 14 gallons.
All we have to do is multiply 11 by 14
11 x 14 = 154
Now the question says to estimate. And our answer can be rounded down to 150 gallons.
So your answer is..
B.) 150 gallons.
Good Luck! :)
Answer: V = (10.4 mph, 38.6 mph)
Step-by-step explanation:
The velocity is written as (vx, vy)
where vx is the component of the velocity in the x-axis and vy is the component of the velocity in the y-axis.
In usual notation, the angles are measured counterclockwise from the positive x-axis.
We know that the angle is 75°, this means that the velocity in the x-axis will be equal to the total velocity of the bird projected in the x-axis (suppose a triangle rectangle, where the velocity is the hypotenuse, the x component is a cathetus and the y component is other cathetus)
vx = 40mph*cos(75°) = 10.4 mph
vy = 40mph*sin(75°) = 38.6mph
Then the vector of velocity is V = (10.4 mph, 38.6 mph)
