One end of a ladder 32 feet long is placed 10 feet from the outer wall of a building that stands on the ground level. How far up
ladessa [460]

Answer:

30 ft

Step-by-step explanation:

This is a classic right triangle problem, where the length of the ladder represents the hypotenuse, where the ladder is lengthwise from the building is the base of the triangle, and what we are looking for is the height of the triangle.  Pythagorean's Theorem will help us find this length.

32^2-10^2=y^2 so

1024 - 100 = y^2 and

y = 30.4 so 30 feet

−−→AB=(xy)<br><br> What values should <br> x<br> and <br> y<br> take?
laiz [17]

The values of x and y are 2 and 0, respectively

The complete question is given below:-

−−→AB=(xy) a line is given in the question from the image given in the question What values should x and y take?

<h3>How do determine the value of x?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

From the graph, we have the following highlights:

Point A is at:

A = 2

The point B is located at:

B = 0

The coordinate (x,y) is represented as:

(x,y) = (A,B)

So, we have:

(x,y) = (2,0)

Hence, the values of x and y are 2 and 0, respectively

Theresa Corporation, which manufactures baskets, is developing direct labor standards. The basic direct labor rate is $18.00 per
Stella [2.4K]

Answer:

$24.52

Step-by-step explanation:

The basic direct labor rate = $18.00 per hour.

Payroll taxes are 14% of the basic direct labor rate

So, payroll Tax = 14% of 18

So, payroll Tax = \frac{14}{100} \times 18 = 2.52

Fringe benefits such as vacation and health care insurance, are $4.00 per hour.

So, standard rate per direct labor hour= $18.00 +$2.52+$4.00

Standard rate per direct labor hour= $24.52

Hence the standard rate per direct labor hour is $24.52
