what is a square root?
Answer:
A number multiplied by its self for ex 7 x 7 = 49 square root of 49 is 7
Answer:
A square root of a number is a value that, when multiplied by itself, gives the number. 6 · 6 = 36, so a square root of 36 is 6. You are probably curious why I said a square root and not the square root. - 6 · - 6 = 36. - 6 is a square root of 36. The symbol is √ which always means the positive square root.
√1 = 1
√4 = 2
√9 = 3
√16 = 4
√25 = 5
√36 = 6
√49 = 7
√64 = 8
√81 = 9
√100 = 10

Glenn has a garden that is shaped like a rectangle.
The perimeter of his garden is 7012 feet.
The length of the garden is 2434 feet.
What is the width of the garden?
21 ft o 11ft o 10 ½ ft o 45 ¾ ft
Answer:
Solution given:
The length of the garden[l] = 2434 feet.
breadth or width [b]=b
perimeter of his garden = 7012 feet.
2[l+b]=7012ft
2434+b=7012/2
b=3506-2434
b=1072
So the width of the garden is 1072ft.

Step-by-step explanation:
a number y is 15 larger than a positive number x. if their sum is not more than 85, what are the possible values of y?
Answer:
y = x + 15 –(1)
x + y = 85
Putting (1)'s value,
x + x + 15 = 85
2x + 15 = 85
2x = 85 - 15 = 70
x = 70/2 = 35
[tex][/tex]
The value of y is 50.
Two simultaneous equations can be formed from the given question:
y - x = 15 equation 1
y + x = 85 equation 2
In order to determine the value of x, subtract equation 1 from 2
2x = 70
Dvidie both sides of the equation by 2
x = 70 / 2
x = 35
Substitute for x in equation 1
y - 35 = 15
y = 35 + 15
y = 50

Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have
2 x 4k - 2 x 3
which gives you
8k - 6
Answer:
Taniyah
Step-by-step explanation:
Taniyah is correct because you need to:
diistribute : 8k - 6 - 6k = 14
combine like terms : 2k - 6 = 14
add 6 to both sides : 2k - 6 + 6 = 14 + 6
simplify : 2k = 20
divide both sides by the same factor : 2k/2 = 20/2

What is the distance between two points(0,0)(-3,5)
Step-by-step explanation:
Think of it like a right triangle. Do you have a graph handy?
Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.
Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?
All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.
9+25=34
√34 is our hypotenuse & distance between the points

A cylinder has a diameter of 18cm and a height of 4cm.
The radius is 12cm
The volume of the cylinder is324 п cm
The volume of the cylinder is1296 п cm
The area of the base of the cylinder is 81 п cm?
Answer:
The volume of the cylinder is324 п cm
The area of the base of the cylinder is 81 п cm
Step-by-step explanation:
volume of a cylinder = nr^2h
n = 22/7
r = radius = 18/2 = 9
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
n x (9^2) x 4 = 324n
Area of the base of the cylinder : Area of a circle = πr² = π x 9^2 = 81 π

Answer:
The probability that the third student will draw a green is 19%.
Step-by-step explanation:
Definition of Probability Probability means possibility of occurrence. It is a branch of mathematics which deals with the occurrence of particular event out of some random events.Given marbles 10 red, 10 blue, 8 green, 8 purple, and 8 yellow marbles .
Therefore total marbles will be 44.
Since the first student in the room draws a yellow, and the second draws a blue ,thus remaining marbles will be 42.
So, the probability that the third student will draw a green is [tex]\frac{8}{42}[/tex]×[tex]100\\[/tex] = 19%
