Answer:
12cm
Step-by-step explanation:
This is a problem which can be solved with the pythagoras therom.
[tex]a^{2} +b^{2} =c^{2}[/tex]
Plus we can split this triangle into two triangles.
The split triangle has dimensions of 13(bc) by 5 cm(dc).[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]5^{2} +b^{2} =13^{2}[/tex]
Now we solve for b which is the lenght of bd
[tex]25 +b^{2} =169[/tex]
[tex]b^{2} =144[/tex]
[tex]b = \sqrt{144}[/tex]
[tex]b = 12[/tex]
Therefore the lenght of bd is 12cm
Hope this helps! :)
To start, you can see that this is a large triangle divided in half to create 2 right triangles. This means we can use the Pythagorean theorem (a^2) + (b^2) = (c^2) to find the segment bd.
To use the theorem we must know at least 2 values of the sides of the triangle. Since segment ac = 10 cm, we can divide this by 2 to get the base values of the smaller triangles, which would be 5 cm.
So a = 5 cm, c = 13 cm
Now, we have what we need and we can plug it in to the equation:
(5 cm)^2 + b^2 = (13 cm)^2
25 cm + b^2 = 169
b^2 = 144
b = 12 cm

Answer:
Part 1) 150
Part 2) 6
Step-by-step explanation:
Part 1) All you have to do is multiply 30 by 5, since 30 is only 20% of the number and you have to get to 100%
30×5 = 150
Part 2) There are multiple ways of doing this, but the way I did it is 30 divided by 100 so you have the number of each percentage. Then you multiply that number by 20 since you are trying to get 20%
30÷100 = 0.3
0.3×20 = 6

Which pay rates are common ways employers pay employees?
commission
daily pay
hourly pay
quarterly pay
salary
Answers
Answer:
The employers pay their employees based on hourly rates, commission and salary.
Step-by-step explanation:
The employees get their pay based on hourly rates that can range from a minimum hourly rate of say $12 per hour to any maximum figure like $40 per hour.
The final salary is based on the numbers of hours worked multiplied by the hourly rate.
Secondly, the pays are also commission based. That is your base salary plus the commission.
The salary is typical in management positions. These are not hourly based but a lump sum pay.
So, the correct answers are : commission, hourly pay and salary.

16 x 18 = 288
There were already 16 sets before that so lets add those as well
288 + 16 = 304
Now since there are 4 teachers we divide this among them
304/4 = 76
76 is the answer.

draw the line which will represent the graph of the equation y-2.5x=c if it's known it passes through the point K(2, -3)
Answers
Answer: y=2.5x-8, the two points necessary to graph would be (2,-3) and (0,-8)
Step-by-step explanation: If the line passes thru (2,-3), let us plug in and find c. -3-2.5(2)=c
-3-5=c
c=-8 so y=2.5x-8
The line will represent the graph of the equation y=2.5x-8.
The two points necessary to graph would be (2,-3) and (0,-8).
What is the slope-intercept form?
The slope-intercept form is y=mx+c
If the line passes through (2,-3),
let us plugin and find c.
So we get,
[tex]-3-2.5(2)=c[/tex]
[tex]-3-5=c[/tex]
[tex]c=-8[/tex]
So, The equation of the line is y=2.5x-8.
