Answer:
You need four squares.
On the top left square, you put the number 20 over it, and the number 30 to it's left. Put the number 600 in the square.
Next, the bottom left square. But the number 8 on the left side of the square, and put the number 160 in the square.
Now, the top right box. put the number 4 over it, and fill it with the number 120.
Last, fill the bottom right square with the number 32.
I'll finish this in a comment or get a mod to open it, but the way it reads, it beeps 67.2 times in those 12 hours. Did you mean per hour?
67.2 / 12 = 5.6
See comment below. The question is the number of beeps in 1 hour which is 5.6 <<<< Answer
Answer:
102.62
Step-by-step explanation:
I converted everything to inches and then solved for x by putting 58 in. over 66 in. (the girls shadow in in.) and the X in. over 1500 in. I cross multiplied (58 x 1500 and 68 x X) and then divided 68 by the result of 58 x 1500.
Answer:
The answer to your question is:
7.- y = 6 units
8.- a = 10.6 in
9.- 41.6 ft
Step-by-step explanation:
7.- That is a right triangle and the hypotenuse is y.
Use the pythagorean theorem to find y.
y² = (3√2)² + (3√2)²
y² = 9(2) + 9(2)
y² = 18 +18
y² = 36
y = 6 units
8.-
hypotenuse = 15 in
c² = a² + b²
a = b so
c² = a² + a²
c² = 2a²
c² / 2 = a²
a² = 15² / 2
a² = 112.5
a = 10.6 in
9.-
Use trygonometry to solve this triangle
height = 36 feet
sin Ф = 36 / hypotenuse
hypotenuse = 36 / sin Ф
hypotenuse = 36 / sin60
hypotenuse = 36 / 0.86
hypotenuse = 41.6 ft
Answer:
constant (unchanged) ratio of two variable quantities.
Step-by-step explanation:
Constant of Variation. The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y = k x (or y = k x ) where k is the constant of variation .
