A rate is a special ratio in which the two terms are in different units. A rate is a little bit different than the ratio, it is a special ratio. For this case, the rate would have units of miles per minutes. We calculate as follows:
rate = 36 miles / 45 min = 0.8 miles per min
distance traveled = 0.8 miles per min ( 60 min ) = 48 miles
Answer: G= 0.0148
Explanation:
Let n = number
"3 times the sum of a number and 7" translates to 3(n + 7)
"2 less than five times the number" translates to 5n - 2
The word "is" becomes the equals sign.
3(n + 7) = 5n - 2
I think you already asked this one.
Answer:
You can solve by the formula of area of trapezium. This is h(a+b)/2.
54 = 6(8+b)/2
Thus b = 10cm.
Answer: see graph
<u>Step-by-step explanation:</u>
Look at the Unit Circle to see the coordinates of the quadrangles.
Build a sine table for one period (0° - 360°).
<u> x </u> <u> y = sin(x) </u> <u> y² = (sin(x))² </u> <u> (x, y²) </u>
0° sin(0°) = 0 (0)² = 0 (0°, 0)
90° sin(90°) = 1 (1)² = 1 (90°, 1)
180° sin(180°) = 0 (0)² = 0 (180°, 0)
270° sin(270°) = -1 (-1)² = 1 (270°, 1)
360° sin(360°) = 0 (0)² = 0 (360°, 0)
Now plot the (x, y²) coordinates on your graph.
