Answer:
The number 1,254 is divisible by all of the following, except 9
Answer:
Length is 20 meters and Width is 16 meters
Step-by-step explanation:
A parallelogram is a 4-sided figure with 2 pair of parallel sides.
The perimeter is the sum of all 4 sides of the parallelogram.
Let the length of parallelogram be x and width be y.
The perimeter is 72, thus we can write:
x + x + y + y = 72
or
2x + 2y = 72
Also, width is 4 less than length, thus we can write:
y = x - 4
Now, we replace the 1st equation with the 2nd equation and solve for x first. Shown below:
2x + 2y = 72
2x + 2(x - 4) = 72
2x + 2x - 8 = 72
4x = 72 + 8
4x = 80
x = 80/4 = 20
And now y:
y = x - 4
y = 20 - 4
y = 16
Thus, the Length is 20 meters and Width is 16 meters
Answer:
Step-by-step explanation:
sin 67 = x/21
x = 21 sin 67
answer is A
Picture a right triangle whose hypotenuse is of unknown length. Let's call that length L. The triangle side opposite the 70 degree angle is then 20 feet. I'd suggest you actually draw this triangle.
Then, using the definition of the sine function,
sin 70 deg = opp / hyp = (20 ft) / L. Transforming this equation, L sin 70 deg = 20 ft. Solving for L:
L = (20 ft) / (sin 70 deg) = 21.28 ft
The ladder length must be 21.28 ft.
Answer:
, 
Step-by-step explanation:
If 26x = 1, then 1x = 1/26 (0.03846). The same logic can be applied to the second answer. If 50x = 1, then 50x = 1/50 (0.02).
