Answer:
Therefore the area of the screen cleared is 1414.28 cm².
Step-by-step explanation:
Given:
a windscreen wiper of a vehicle of length 30 cm
Consider this length as Radius of Semicircle, r = 30 cm
clears out an angle of 180 degrees implies Semicircle Shape
pie=22/7
To Find:
Area of the screen cleared
= ?
Solution:
We have
Substituting r and pie we get
Therefore the area of the screen cleared is 1414.28 cm².
Answer:
concrete operational stage
Step-by-step explanation:
Have a look at the attached photo below, it may be your full question:
The concrete operational stage is the third phase in Piaget's cognitive development theory. This period spans the period between childhood, it begins around 7 years of age and continues until about 11 years of age and is characterized by the development of logical thinking.
Answer:
6
Step-by-step explanation:
first, we need to find the GCF (Greatest Common Factor) which is the highest number that can go into every number in the equation (In this case, those numbers are 24 and 30)
The GCF for this would be 6, meaning that there would be 6 bags with and equal amount of granola bars and protein bars.
To be more specific, every bag would have 4 granola bars and 5 protein bars.
Answer:
On a coordinate plane, a line goes through (0, 3) and (2, 4) and another line goes through (0, 3) and (0.75, 0).
This answer almost coincide with option C. I suppose there was a mistype.
Step-by-step explanation:
The system of equations is formed by:
–x + 2y = 6
4x + y = 3
In the picture attached, the solution set is shown.
The first equation goes through (0, 3) and (2, 4), as can be checked by:
–(0) + 2(3) = 6
–(2) + 2(4) = 6
The second goes through (0, 3) and (0.75, 0), as can be checked by:
4(0) + (3) = 3
4(0.75) + (0) = 3
