Answer:
Step-by-step explanation:
Hello
A1 = (B + b) x h / 2
A1 = (8 + 2) x 5 / 2
A1 = 10 x 5 / 2
A1 = 25 cm^2
A2 = L x l
A2 = 6 x 8
A2 = 48 cm^2
A = A1 + A2
A = 25 + 48
A = 73 cm^2

In a 45 - 45 - 90 triangle the two smaller sides are =. So when you use
a^2 + b^2 = c^2, you need a and b both to find the area.
So call both of them = b^2.
Equation and solution
a^2 + b^2 = c^2
b^2 + b^2 = c^2
2b^2 = c^2
c = 24
b = ???
2 b^2 = 24^2
2 b^2 = 576 Divide by 2
b^2 = 288 I'm going to leave this as it is for the moment. You'll see what in a second.
Area of a triangle
Area of a triangle = 1/2 h * b
But the height and base are the 2 smaller equal sides of a 45_45_90 triangle
so h = b
base = b
Area of a triangle = 1/2 b^2 The equalities above tell you that. h and b of the triangle are equal.
Area = 1/2 288 feet^2
Area = 144 feet^2

Answer: 40 minutes</h3>
============================================================
Explanation:
The distance traveled is d = 80 miles.
When going to work, her speed is r = 60 mph. She takes t = d/r = 80/60 = 4/3 hours which converts to 80 minutes. Multiply by 60 to go from hours to minutes.
Notice how the '80' shows up twice (in "80 miles" and "80 minutes"). This is because traveling 60 mph is the same as traveling 1 mile per minute.
-----------------
Now as she's coming home, her speed becomes r = 40 and she takes t = d/r = 80/40 = 2 hours = 120 minutes.
The difference in time values is 120 - 80 = 40 minutes.
Her commute back home takes 40 more minutes compared to the morning drive to work.
ANSWER
Each side of the chip is 5 centimeters long.
<u>EXPLANATION</u>
The chip is in the form of a square.
The formula for finding the area of a square is
We were given in the question that, the area is 25 square centimeters. This means that,
We take the square root of both sides to get,
Hence the length of the square technology chip is 5 centimeters
Answer:
It is an isosceles triangle so the 6 is not correct. We can use the Pythagorean Theorem and 64 does not equal 36+16.
