Answer:
Area : 37cm^2
Perimeter : 29 cm
Step-by-step explanation:
If you need to find the perimeter you just add all of the sides together
7 + 7 + 1.5 + 1.5 + 4 + 4 + 4 = 29
If you want to find the area you can split the shape into simpler ones that you know how to find the area. In this case you can split it into a triangle and a square.
Square : 4 × 4 = 16cm^2
Triangle : [(4+1.5+1.5)(6)]/2 = 21cm^2
Then add them together
16cm^2 + 21cm^2 = 37cm^2
B. should be the correct answer.
Answer:
A = (100 - y)y
Maximum area = 2500 sq. feet.
Step-by-step explanation:
Let the length of the combined rectangular area is y feet and the shared width is x feet.
So, perimeter of the two rectangle together is (3x + 2y) = 200 {Given}
⇒ 2y = 200 - 3x
⇒ ...... (1).
a) Now, area of the total plot in sq. feet is ........ (2)
So, this is the expression for area A in terms of length of shared side x.
b) For area to be maximum the condition is
Now, differentiating equation (2) on both sides with respect to x we get
⇒ x = 33.33 feet.
So, from equation (1) we get
⇒ x = 50 feet.
So, the value of maximum area = 50 × 33.33 = 1666.5 sq. feet. (Answer)
Answer:
Step-by-step explanation:
Please, share the possible answer choices next time.
The graph of a parabola y = x^2 has its vertex at the origin, (0, 0), and opens up. By replacing x with (x - 3), we translate the graph 3 units to the right.
Less than 3 is about 10.75% and greater than 13 is about 6.18%.
To find these percents, you need to find the z-score for each value. Then, use your table to find the correct percent. Be sure to find the side above 13 when you use your chart.
For less than 3:
(3 - 7.45) / 3.6 = -1.24 = The percent below this is 0.1075
For greater than 13:
(13 - 7.45) / 3.6 = 1.54 = The percent above this is 0.0618
