1/5 of 20 is $4. so 20-4=$16 remaining
3/8 of 16 is $7.50. So, 16-7.50= $8.50 remaining
2/7 of 8.5 is $2.43. So, 8.50-2.43 is $6.07
Answer: $6.07 is the amount ken has remaining
Answer:
The answer is 25.42 ft
Step-by-step explanation:
Let's start by finding the perimeter of the semi circle up top. The formula to do this is R(pi +2). So I did 3(3.14 + 2). You would get 15.42 to that. Then I added 5 ft twice for both of the triangles. leaving you with 25.42 ft.
C(a,b), because the x-coordinate( first coordinate) is a (seeing as it is situated directly above point B, which also has an x-coordinate of a) and the y-coordinate ( second coordinate) is b (seeing as it is situated on the same horizontal level as point D, which also has a y-coordinate of b)
the length of AC can be calculated with the theorem of Pythagoras:
length AB = a - 0 = a
length BC = b - 0 = b
seeing as the length of AC is the longest, it can be calculated by the following formula:
It is called "Pythagoras' Theorem" and can be written in one short equation:
a^2 + b^2 = c^2 (^ means to the power of by the way)
in this case, A and B are lengths AB and BC, so lenght AC can be calculated as the following:
a^2 + b^2 = (length AC)^2
length AC = √(a^2 + b^2)
Extra information: Seeing as the shape of the drawn lines is a rectangle, lines AC and BD have to be the same length, so BD is also √(a^2 + b^2). But that is also stated in the assignment!
Dilation creates similar triangles, all the others are isometries, making congruent triangles. Choice a.
Answer:
x=5
Step-by-step explanation:
Isolate the x by adding 9 on both sides:
Take the square root of both sides:
Simplify:
<u>x=5</u>
