Answer:
[tex] x = 4 \sqrt{3} [/tex]
Step-by-step explanation:
By Pythagoras Theorem:
[tex] {x}^{2} = {( \sqrt{8 \times 4}) }^{2} + {(4)}^{2} \\ \\ {x}^{2} = {( \sqrt{32}) }^{2} + {(4)}^{2} \\ \\ {x}^{2} = 32 + 16 \\ \\ {x}^{2} = 48 \\ \\ x = \sqrt{48} \\ \\ x = \sqrt{ {4}^{2} \times 3} \\ \\ x = 4 \sqrt{3} [/tex]

There are 2 cats to 5 dogs. Which of the following is an equivalent ratio of cats to dogs?
Answers
Answer:
See below.
Step-by-step explanation:
The ratio of cats to dogs would be 2/5. This is the simplest ratio, but I assume you are looking for other ratios that are equal to 2/5
Since you did not provide choices to pick from, I can't really answer your question. But, some ratios that are equal to 2/5 are 4/10, 6/15, 8/20, and 10/25.

Answer:

Step-by-step explanation:
If X is the center of rotation, the coordinates of point P are transformed like this:
P' = -(P -X) +X
P' = 2X -P
(x, y) ⇒ (2(-5) -x, 2(3) -y)
(x, y) ⇒ (-10-x, 6-y)
__
Your points are transformed to ...
A(-8, 5) ⇒ (-10-(-8), 6-5) = A'(-2, 1)
B(-6, 9) ⇒ (-10-(-6), 6-9) = B'(-4, -3)
C(-3, 6) ⇒ (-10-(-3), 6-6) = C'(-7, 0)
These coordinates match the first choice.

The ratio of the perimeter of a square A and square B is 4:3. The side of square B is 3 m less than the side
of square A. What is the length of the side of square A?
please answer
Answers
Answer:
x = 12
Step-by-step explanation:
x = length of side of square A
'x-3' represents length of side of square B
Perimeter of square A = 4x
Perimeter of square A = 4x - 12
we can set up the following proportion based on ratio of 4:3
4x / 4 = 4x - 12 / 3
cross-multiply:
4(3x) = 4(4x-12)
12x = 16x - 48
-4x = -48
x = 12
the breadth of a rectangular handkerchief is 10 cm shorter than its length .if the perimeter of the handkerchief is 100cm. find its length and breadth..
plz help me
Answers
Step-by-step explanation:
Perimeter = 2(l+b)
2(x+x-10)=100cm
(x+x-10)= 100 divided by 2
(x+x-10)=50
2x-10=50
2x=50+10,60
x=60 divided by 2
X =30
Length = 30cm
Breadth= 30-10= 20cm
PLEASE MARK MY ANSWER AS THE BRAINILIEST!
Answer:
solution given:
length[l]=xcm(let)
breadth [b]=(x-10)cm
perimeter of rectangle [P]=100cm
we have
P=2[l+b]
100cm=2[x+x-10]
2x-10=[tex] \frac{100}{2} [/tex]
2x=50+10
x=[tex] \frac{60}{2} [/tex]
:.x=30cm
So
length[l]=x=30cm
breadth [b]=(x-10)=30-10=20cm
