Answer:
22cm²
Step-by-step explanation:
For the area of triangle,
base = 2 + 2 + 2 = 6cm
height = 4cm
Area = 1/2 x base x height
= 1/2 x 6 x 4
= 12cm²
For area of the rectangle,
length = 5cm
breadth = 2cm
Area = length x breadth
= 5 x 2
= 10cm²
Area of compound shape = 12 + 10 = 22 cm²
The first option 0.65 might be right
First w have to figure out the solution o the right side of the equation
So (insert long line here) = 8+32
We simplify it
(Insert long line here) = 40
So, you hen ask yourself what options are equal to 40 ( which is the second option)
Option b
Answer:
636 kilopascals
Step-by-step explanation:
4 x 10 is 40
It will lose 40% after 4 minutes
Multiply 1060 by 0.60
The answer is 636 kilopascals
Answer:
y = 0.5sin(4x)
Step-by-step explanation:
y = A sin(B(x + C)) + D
amplitude is A = 0.5
B = 2π/period = 2π / (1/2 π) = 4
phase shift is C (positive is to the left) = 0
vertical shift is D = 0
