The answer for PA is 60/13. This is found by
The area of the rectangle is 60, therefore, the big triangle areas are 30 each. We know that the hypotenuse is 13, so therefore, we get
1/2(13*PA) = 30. This then simplifies to
13 * PA = 60, which then turns into
PA = 60/13.
Hope this helps and have a nice day:)
You need to know 20% of $5000. "Of" means "times".
$5000 x 0.20 (which is 20% written as a decimal)
=$1000 profit she wants to make
$5000 (original price) + $1000 (profit) = $6000 (sale price)
Answer:
scientists
Step-by-step explanation:
Answer: Driven gear will have 50 teeth, and driver gear will have 42 teeth
Step-by-step explanation: First we have to know the formula of gear ratio which is started below
(No of teeth on driven)/(No of teeth on driver)
Note: we should all know in the combination of a gear system, we have two gears, the driver gear and the driven gear
So since the least amount of teeth for any gear is 50, we assume the no of teeth on the driven is 50
And no of teeth on the driver is x
50/x = 1.1839323
Cross multiply
x x 1.1839323 = 50
x = 50/1.1839323
x = 42.23
To the nearest whole number = 42
So therefore, number of teeth on the driver gear is 42
