Answer:
29.7cm²
Step-by-step explanation:
The area of the shaded region = area of rectangle - area of circle
Area of rectangle:
A=lw
=7*5
=35cm²
Diameter of circle is 2.6cm. Radius is half diameter: 2.6/2=1.3cm
Area of circle:
A=πr²
=(3.14)(1.3²)
=5.3066cm²
35 - 5.3066 = 29.6934cm²
Answer:
No
Step-by-step explanation:
Let's calculate sinA and sinB.
sinA = opposite / hypotenuse = 12 / 20
sinB = opposite / hypotenuse = 16 / 20
Since 12 / 20 ≠ 16 / 20, she is incorrect.

Answer:
the answer is
x = 4
Step-by-step explanation:
hope it helps you
She has 6 kids (2 boys, 4 girls, since her total amount of kids is three times the amount of boys, 2 x 3 = 6 total)
4 girls : 2 boys
compare ratios with the answer choices.
4:2 =\= 4:8
4:2 =\= 8:6
4:2 =\= 6:9
4:2 = 12:6 ! When you multiply 4:2 by 3, you get 12:6.
I hope this helps!
