Easy
rectangle and half circle
rectangle=9 times 3=27
circle
diamter is 9 so radius i s9/2=4.5
area=pir^2 or pi*4.5^2=20.25pi
halve that since it is 1/2 circle
10.125pi
add
27+10.125pi=
27+31.7925=
58.7925
rounded to 58.8
2nd option
Answer:
-7/5 is greater than -1 1/5 because -7/5 lies above -1 1/5 on a vertical number line.
Step-by-step explanation:
I hope this is correct. If not I'm so sorry!
Answer:
A. 110
Step-by-step explanation:
Angles 4 and 6 are supplementary so if we add them together they will equal 180.
(5a + 10)° + (3a + 10)° = 180°
Simplify a bit to get 8a + 20 = 180
and 8a = 160.
a = 20. Now sub that value of a into the expression for angle 4:
5a + 10 --> 5(20) + 10 = 110°
Parallel lines have same slope.
The slope would be y=3x
Perpendicular lines have opposite reciprocal for the slope.
The slope would be y=-4/3
Answer:
9.7*10^9 or 9,700,000,000
Step-by-step explanation:
To find the answer, multiply 9.7 * 10^6 by 1000 times becasue 1kg = 1000g, we got:
9.7 * 10^6 * 1000 = 9.7*10^9 or 9,700,000,000
Hope this help you :3
