The answer is 30
WoSo at 7 PM, the hour hand is on 7 and the minute hand is on 12.
That is a gap of five hours.
The whole clock has twelve hours.
We know that a clock is a circle.
A circle has 360 degrees.
So, the 12 hours of a clock make 360 degrees.
Each hour is 360/12=30 degrees.
So, 5 hours makes 30*5=150 degrees.
Answer:
5x + 13y
Step-by-step explanation:
-x + 9y- (-6x) + 4y
-x + 9y + 6x +4y
(-x + 6x) + (9y + 4y)
5x + 13y
12.5 Quarts
Explanation:
It takes 4 cups to make a quart so 2.5 would equal 0.625 quart
Then you would take 0.625 x 20 which would then equal 12.5 Quarts
Answer:
249 cm^2
Step-by-step explanation:
This problem becomes easier if we subdivide the figure, find the areas of the resulting figures and then sum them up.
Draw a vertical line straight down from the edge marked "4 cm" towards the edge marked "18 cm." The resulting rectangle on the left is 15.5 cm long and (18 - 7.5) cm wide, or 15.5 by 10.5 cm. Its area is 162.75 cm^2.
Next, find the area of the rectangle on the right of the line we drew. Its width is 7.5 cm and its height (15.5 - 4) cm, resulting in an area of 86.25 cm^2.
Last, add together these two subareas: combine 86.25 cm^2 and 162.75 cm^2. The total area of the composite figure is then 249 cm^2 (answer).
