How would you find the area of the shaded region?
Whitepunk [10]

Answer:

The Area of the shaded region = (Area of the largest circle) – (Area of the circle with radius 3) – (Area of the circle with radius 2). Whatever is left over is the shaded region. The diameter of the largest circle is 10, so its radius is 5 and thus its area is 25π. SO do this in that problem and you will get the answer.

How to add and subtract rational numbers in fraction form?
Daniel [21]
First you have to convert  the denominators to the Lowest Common Multiple (unless the denominators are equal, of course).

Example   1/4 + 1/2

The LCM of 2 and 4 = 4   so we can write 1/2  as 1*2/2*2 = 2/4. 
Now we can add:-
1/4 + 2/4 = 3/4.

Same thing goes for subtraction.

Example 2:-

5/6 - 1/7  :- 
LCM of 6 and 7  = 6*7 = 42  so we have:-
5*7 / 6*7   - 1*6 / 7*6  
= 35/42 - 6/42  =  29/42

A ball is thrown upwards and it’s height h m,at time t s,is given by h=7t-4.9t2.How long does the ball spend more than 1.5m abov
Allushta [10]

Answer:  From what you wrote the I think the ball is drop

At time 0 you are 7 meters above ground

You basically just need to solve for

1.5 =7t-4.9t^2

by rearrange the equation you get

4.9t^2-7t+1.5=0

by using Quadratic Formula

t=1.166s

Mandisa draws a rectangle to represent the area of her yard. The area can be represented by 10x2 – 13x – 14.
andrew-mc [135]

Answer:

(x-2) and (10x+7)

Step-by-step explanation:

10x²-13x-14

10x²-20x+7x-14

10x(x-2)+7(x-2)

(x-2)(10x+7)

the factors are (x-2)(10x+7)

meaning that the length and breadth are (x-2) and (10x+7)
