Explanation:
C is the midpoint of AB. This means AC is half as long as AB
Put another way, AB is twice as long as AC
AB = 2*AC
AB = 2*( AC )
32 = 2*( x/2 + 10 ) .... substitution
32 = 2*(x/2) + 2*10 ... distribute
32 = x + 20
x+20 = 32
x = 32-20 .... subtract 20 from both sides
x = 12
---------
If x = 12, then
AC = x/2 + 10
AC = 12/2 + 10
AC = 6+10
AC = 16
which is half of AB = 32, so it confirms our answer.

DEF is a right traingle if the three sides are 24 40 and 17
Answers
If it is, then the squares of the short side and the medium side add up to the square of the longest side.
Let's check it out:
Square of the short side = 17² = 289
Square of the medium side = 24² = 576
These two squares add up to (289 + 576) = 865
Square of the longest side = 40² = 1,600
865 is not equal to 1,600.
So these three numbers do not make a right triangle.

Please select the best answer from the choices provided
A
B

D
Answers
Answer:
The answer is B!
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 63000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 63000, so we can write it down as 100%=63000.
4. We know, that x% equals 17000 of the output value, so we can write it down as x%=17000.
5. Now we have two simple equations:
1) 100%=63000
2) x%=17000
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=63000/17000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 17000 is what percent of 63000
100%/x%=63000/17000
(100/x)*x=(63000/17000)*x - we multiply both sides of the equation by x
100=3.7058823529412*x - we divide both sides of the equation by (3.7058823529412) to get x
100/3.7058823529412=x
26.984126984127=x
x=26.984126984127
now we have:
17000 is 27% of 63000

-27%

a rectangular television's length is 3 inches more than twice its width. The perimeter of the television is 144 inches. What is the width of the television?

can someone explain bc I got small brain ykyk
Answers
Answer: A. 23
23 - Width
23x2 = 46
46+3 = 49
So..
49 - Length
lx2+wx2 = perimeter
49x2 = 98
23x2 = 46
98+46 = 144
The width of the television will be 23 inches. Then the correct option is A.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
The length of a rectangular television is 3 inches longer than its width. The display has a 144-inch perimeter. Then the equation is given below.
L = 2W + 3 ...1
144 = 2(L + W) ...2
From equations 1 and 2, then have
144 = 2(2W + 3 + W)
72 = 3W + 3
3W = 69
W = 23 inches
The width of the television will be 23 inches. Then the correct option is A.

Given the above equation, what is the value of
10-[(a -3) - 7]?
Answers
Answer:
10
Step-by-step explanation:
a=3+7
a=10
10-[(10-3)-7]=
=10-[7-7]=
=10-0=
=10
The solution of expression 10 - [(a - 3) - 7] would be 10.
Given that,
The equation is,
-7 + a = 3
Now, we can simplify the equation as,
- 7 + a = 3
a - 7 = 3
Subtract 3 on both sides,
a - 3 - 7 = 0
(a - 3) - 7 = 0 .. (i)
Here, the equation to simplify is,
10 - [(a - 3) - 7]
Substitute the value from equation (i),
10 - 0
= 10
Therefore, the solution of expression is 10.
