Answer:
Since we have two semi-circles we can say that we have a full circle. using the circle area formula we can say that
3.14*2^2 = 12.56 cm
Using the rectangle area formula we can say that
19*4 = 76 cm
Adding them both together is
12.56 + 76 = 88.56 cm
So the bookmark has an area of 88.56cm^2
Answer:
Step-by-step explanation:
139 +10 = 149
149 / 8 = 18.625
round to nearest hundredth = 18
So pemdas
square root of 9 means 9^(1/2) so it counts as an exponent so
9=3 times 3 so square root of 9=3
square root of 25
do pemdas so exponents before division
25=5 times 5 so
square root of 25==5 so
3/5=0.6
Answer:
The system of inequalities that represents this situation will be:


Step-by-step explanation:
- Let 'f' represent the first number
- Let 's' represent the second number.
Given that the sum of the two numbers is less than 10. As 'less than' can be represented by '<'.
- so the inequality would be: f + s < 10
Given that If we subtract the second number from the first, the difference is greater than 3. As 'greater than' can be represented by '>'.
- so the inequality would be: f-s > 3
Thus, the system of inequalities that represents this situation will be:


Given:-

To find:-
Wheather the given sides form a valid triangle.
So now let,

To check we use the condition,

Substituting the values we get,

In the above condition 12+7>20 is wrong.
So the condition fails and the given sides doesnt form a triangle.
