Answer:

$2772$

Step-by-step explanation:

The amount of books that will not be returned are $45$ % $=45/100=9/20$ , multiplied by $5040$ . We multiply it by $5040$ because $45$ % $(5040)=45$ % $*5040$ .

$45/100*(5040)=9/20*(5040)=9/2*504=9*252=2268$ , so the answer is $2268$ , right?

Wrong! $2268$ is the amount of books that will NOT be returned on the due date. We need the amount of books that WILL be returned on the due date. So, the real answer is $5040-2268=2772$ .

So, the answer is $\boxed{2772}$ and we're done!

What is the gradient of the graph shown

Keith_Richards [23]

9514 1404 393

Answer:

Step-by-step explanation:

The gradient is the ratio of "rise" to "run". Here, it appears the line crosses the y-axis at y = -1. It appears that it also crosses the grid intersection at (1, 2). This represents a "rise" (change in y) of (2 -(-1)) = 3, for a "run" (change in x) of (1 -0) = 1. Then the gradient is ...

m = rise/run = 3/1 = 3

The gradient of the graph is 3.

Employer A is offering you a position for $350000 per year l. Employer B is offering the same job for $18.00 per hour. Assuming

ss7ja [257]

Answer:

Depends

Step-by-step explanation:

In order to see which annual salary is higher, we must calculate the annual salary of B to compare to A. To do this, if B offers $18.00 an hour for 40 hours a week, that's $720 a week. Now to convert this to annual, multiply the weekly earnings by the 52 weeks in a year. Employer B offers $720 × 52 weeks = $37,440 annually. Assuming you didn't have a typo, $350,000 is $312,560 greater meaning A pays more. If you did have a typo, and meant that Employer A offered $35,000, then Employer B would pay more.

Using a pencil, paper, and protractor, or a drawing program, draw an isosceles triangle that has exactly one 50° angle. Use the

Ira Lisetskai [31]

Sorry my lighting is really bad.

Note: my drawing is NOT to scale (because I don't have a protractor)

Ok so an isosceles triangle has 2 congruent sides and 1 other side. That means that the (one) 50° angle is the vertice (edge) of the 2 congruent sides. The vertice of the other sides are 65° because the angles of a triangle add up to 180°.

180°-50°=130°

The other angles are the same so 130° ÷ 2 = 65°

Since the two longer sides are congruent, mark them with one line each.

The other side is different so mark that with two lines.

If another person were given these same instructions, their drawing would look the same.

If you had a protractor, there would be a slight difference but it would still look the same (because a protractor is a tool that is very exact and it is quite accurate).

Also, if you didn't have a protractor, it wouldn't be the same.]

But even if someone else's drawing look different than yours (and mine), but the point would be the same because they know the congruent sides by the markings and they know the angles.

So if another person saw these same instructions and drew the triangle, it would look the same, but it wouldn't be exactly similar.

♡ Hope this helps! ♡
