Answer:
Length of 6 feet
Width of 2 feet
The estimate of the perimeter of the countertop is 16 feet.
Step-by-step explanation:
Rectangle:
A rectangle has two dimensions: The length(l) and the width(w). The perimeter of a rectange is:
P = 2(l + w).
In this question:
Length: 5.75 feet
Width: 2.47 feet.
Round the length and width to the nearest whole number .
5.75 is closer to 6(0.25) than to 5(0.75). So the length is 6 feet.
2.47 is closer to 2(0.47) than to 3(0.53). So the width is 2 feet.
Then estimate the perimeter of the countertop
P = 2(l + w) = 2(6 + 2) = 16
The estimate of the perimeter of the countertop is 16 feet.
Answer:
The area of trapezoid is 32cm².
Step-by-step explanation:
Given that the area of trapezoid formula is A 1/2×(a+b)×h where a, b represents length and h is height :






For this case what we must do is use the law of cosines.
We have then:
12 ^ 2 = 6 ^ 2 + 10 ^ 2 - 2 * (6) * (10) cos (x)
Clearing we have:
cos (x) = (12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10))
x = acos ((12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10)))
x = 93.82 degrees
Answer:
The tree is growing in relation to the hill at:
x = 93.82 degrees
Answer:
Answers are below.
Step-by-step explanation:
Problem 2:
Area = approx. 11.3 (rounded to nearest tenth)
A = 1 / 4b
1/4 x 4 x
11.31371
11.31371 rounded to the nearest tenth is 11.3
Problem 3: i'm not too sure sorry :(
Answer:
replace x with each of the value then solve for the value
Step-by-step explanation:
when raised to the power of a negative you do the inverse
2^-2 = 2^1/2
