As you are looking for 1.75 minutes (or 105 seconds), the best thing to do is to find how many words she can type in 0.25 minutes (this is a quarter, and you can divide 1.75 by this). To find a quarter, you have to divide by 4, 120/4= 30. Therefore, every 15 seconds, Dorothy can type 30 words. As you've got 105 seconds, divide this by 15, and this gives you 7. Then multiply 30 by 7, and this gives you 210.
Dorothy can type 210 words in 1.75 minutes
Hope this helps :)
1/15. 8/60 simplified down is 1/15
Answer:
Area of bigger rectangle = length x breadth = 12 x 9 = 108 square cm
Area of small rectangle = length x breadth = 8 x 5 = 40 square cm
Area of the shaded region = Area of big rectangle - Area of small rectangle
= 108 - 40 = 68 square cm
Answer:
Step-by-step explanation:
Remember that the formula for the difference of squares is 
. The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:
We can conclude that the correct answer is .
So (f-g)(x) is f(x)-g(x) so you have
(3x+10)-(2x-4)
Distribute the negative in to the 2x-4 to get
3x+10-2x+4
Then combing like terms you have
3x-2x+10+4
And then that gives you
x+14
So (f-g)(x)=x+14
