Answers
Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20

the math team has 11 boys 10 girls and 1 coach. What is the ratio of coach to students?
Answers
#3, #19, and #16 please!!
Answers
To answer number 19, do 21-11= 10 This means that X=10
X(10) plus 11=21
21=21
[10 + 11] >_ 21
To solve 16.
Add 3 to 13 to get 16
Then you’ll have [3x +4] >_ 16
Once you have this, subtract 4 from both sides.
Then you’ll have 3x>_ 12
Now you can divide each side by 3 to get x>_4. X=4
So if we plug that in [3x +4] >_ 13, you’ll get
[3(4) +4] >_ 13
And then you’ll get
[16] >_ 13

y!=0/15
y!=0
y∈R

We add all the numbers together, and all the variables
2.6y-4/15y+7/6y-7=0
We calculate fractions

We multiply all the terms by the denominator
(2.6y)*90y^2+(-24y)+105y-7*90y^2=0
We add all the numbers together, and all the variables
(+2.6y)*90y^2+(-24y)+105y-7*90y^2=0
We add all the numbers together, and all the variables

Matt can walk 500 m from his home on King Street, and then 900m along Queen Street to go to his school. He can also walk across a diagonally across a park from his home to his school. Assuming King Street and Queen Street meet at right angles, how far does he walk across the park to go to school?
Answers
Answer:
He walks 1030 meters if he walks across the park.
Step-by-step explanation:
In order to solve this question we will need to know that [tex]c^{2} = a^{2} + b^{2}[/tex] (were c is the length of the hypotenuse (the diagonal line) of a right angle triangle, and a and b are the legs (the sides that form a right angle). So them means that.....
Let "c" be the distance he will need to walk if he was going to go through the park
Let "a" be the distance he walks on King Street
Let "b " be the distance he walks on Queen Street, then.....
[tex]c^{2} = a^{2} + b^{2}[/tex]
[tex]c = \sqrt{a^{2} + b^{2} }[/tex]
(Now plug in the values of a and b and get.....)
c = [tex]\sqrt{500^{2} + 900^{2} }[/tex]
c = [tex]\sqrt{1060000 }[/tex]
c = 1029.563014............
So I would assume that you have to round to the nearest meter. And as a result we get 1030 meter.

The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
Let the unknown number be "x"
The square of an unknown number is expressed as x²4 times the square of a number is 4x²Seven less than 4 times the square of a number is 4x² - 7If the resulting expression is 18, this will be expressed as 4x² - 7 = 18
Solving the resulting expression
[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]
Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

Answer:
Step-by-step explanation:
domain represents the numbers at the x endpoints of a graph.
on the graph we see that on the left, the line ends when x is -4
on the right, the line ends when x is 4
the domain is
-4, 4
but notice how on the left there is an open circle
this will be written with a parentheses

and notice how on the right there is a closed circle
this will be written with a bracket

the equation is 7x-3 over 9 > 8-2x
Answers
Answer:
solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]
First we will solve the inequality to find value of x
Solving:
[tex]\frac{7x-3}{9}\geq 8-2x[/tex]
Step 1: Multiply both sides by 9
[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]
Step 2: Adding 3 on both sides
[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]
Step 3: Add 18x on both sides
[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]
Step 4: Divide both sides by 25
[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]
So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
