A trapezoid is broken into a triangle and rectangle. The rectangle has a base of 10 centimeters and a height of 12 centimeters. The triangle has a base of 4 centimeters and a height of 12 centimeters.
2 answers:
Answer:
area of rectangle = 120 cm²
area of triangle = 24 cm²
area of trapezoid = 144 cm²
Step-by-step explanation:
12 * 10 = 120
12 * 4 = 48
48 / 2
add the triangle and rectangle area together

Answer:
c = 8.06
Step-by-step explanation:
Use the Pythagorean theorem.
a^2 + b^2 = c^2
c^2 = a^2 + b^2
c^2 = 4^2 + 7^2
c^2 = 16 + 49
c^2 = 65
c = sqrt(65)
c = 8.06
Let x be the time and y is the depth
At x = 0 y = -130
At x= 6.5 y = 0
So the slope = (0- (-130) / ( 6.5 – 0) = 20
Y intercept b
0 = 20(6.5) + b
B= -130
The equation
Y = 20x -130
The domain all real numbers from 0 to 6.5
Range is all realnumber from -130 to 0
Answer:

such that
1≤x≤7
.
answer is 77
Step-by-step explanation:
The answer is 216 cubic feet. How? All you have to do is multiply every number then divide it by 2. Like this: 2*12*18=432. 432/2= 216 cubic feet.
The mean of the answer is 20.5 because you add all of the number together and divide by 6 because there's 6 numbers.
