Raymond is installing a new kitchen counter top . The counter top is a rectangular piece of quartz that is 5.75 feet long and 2.

Naddika [18.5K]

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 :

$A = \frac{1}{2} \times (a + b) \times h$

$let \: a = 4,b = 12,h = 4$

$A = \frac{1}{2} \times (4 + 12) \times 4$

$A = \frac{1}{2} \times 16 \times 4$

$A = 8 \times 4$

$A = 32 \: {units}^{2}$

A tree is growing on a hill. In an attempt to make the tree grow straight up, a 12-foot-long wire is attached to a tree at a poi

melisa1 [442]

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
