cosine ( CAH) = Adjacent/ hypothenus
cos9 = x/ 2
let x represent the horizontal distance
2 cos 9 = x
x = 2 (0.98768834)
x = 1.975
x = 1.97
therefore the horizontal dstance jade covers is 1.97km
Answer:
yes these all are correct
Answer:
x=2.4
Step-by-step explanation:
2(x+1)+6=20-3x
We simplify the equation to the form, which is simple to understand
2(x+1)+6=20-3x
Reorder the terms in parentheses
+(+2x+2)+6=20-3x
Remove unnecessary parentheses
+2x+2+6=+20-3x
We move all terms containing x to the left and all other terms to the right.
+2x+3x=+20-2-6
We simplify left and right side of the equation.
+5x=+12
We divide both sides of the equation by 5 to get x.
x=2.4

Draw a line on the hole which forms a square. The square lengths are 3 inches because 12-9 equals 3. 3^2= 9 which is the area of that square below the rectangle. Draw another line to separate the big rectangle into two rectangles. The smaller of these two new rectangles dimensions are 4 by 7 in. 7x4= 28 ft as the area of the smaller rectangle. The dimensions are the larger rectangle are 4 by 9 inch. The area of the larger rectangle is 36 inches.
36+28+9=73 in^2 as the total area.
Her cousin lives 184 miles away
Explanation: In this problem you need to solve for the distance, and you are given speed and time. With this information, we need to use the speed formula which is s=d/t where s=speed, d=distance, and t=time
Next all you have to do is plug in your values, which should look like this-
40=d/4.6
Now that you have your equation, you must solve for d to get your distance by isolating d to one side of the equation. You do this, by multiplying 4.6 on each side of the equation.
This is what the math should look like-
(4.6)40=d/4.6(4.6)
184=d
d= 184 miles
I hope this helped!
