Nidhi is creating a rectangular garden in her back yard. The length of the garden is 10 feet. The perimeter of the garden must be at least 40 feet and no more than 76 feet. Write and solve a compound inequality to find the range of values for the width, w, of the garden.
Answer:
10<=w<=33
Step-by-step explanation:
length is 10 so width can only add up to 20 less than those
40-20=20
20/2=10
76-20=66
66/2=33

One year Hank had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an ERA of
3.05. Also, Sally had the lowest ERA of any female pitcher at the school with an ERA of 2.96. For the males, the mean ERA was 3.848 and the standard deviation was
0.742. For the females, the mean ERA was 5.007 and the standard deviation was 0.722. Find their respective Z-scores. Which player had the better year relative to
their peers, Hank or Sally? (Note: In general, the lower the ERA, the better the pitcher.)

Move all terms containing x to the left side of the equation.
4x-8=12
Move all terms not containing x to the right side of the equation.
4x=20
Divide each term by 4 and simplify.

What is the value of x & y?
Answer:
x = 16, y = 9
Step-by-step explanation:
The 2 triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is
[tex]\frac{x}{24}[/tex] = [tex]\frac{12}{18}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )
3x = 48 ( divide both sides by 3 )
x = 16
----------------------------------------------------
[tex]\frac{y}{6}[/tex] = [tex]\frac{18}{12}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )
2y = 18 ( divide both sides by 2 )
y = 9
Find equations of the spheres with center(1, −1, 6)that touch the following planes.a) xy-planeb) yz-planec) xz-plane
Given :
Center of sphere , C( 1 , -1 , 6 ) .
To Find :
Find equations of the spheres with center (1, −1, 6) that touch the following planes.a) xy-plane b) yz-plane c) xz-plane .
Solution :
a)
Distance of the point from xy-plane is :
d = 6 units .
So , equation of circle with center C and radius 6 units is :
[tex](x-1)^2+(y-(-1))^2+(z-6)^2=6^2\\\\(x-1)^2+(y+1)^2+(z-6)^2=36[/tex]
b)
Distance of point from yz-plane is :
d = 1 unit .
So , equation of circle with center C and radius 1 units is :
[tex](x-1)^2+(x+1)^2+(z-6)^2=1^2\\\\(x-1)^2+(x+1)^2+(z-6)^2=1[/tex]
c)
Distance of point from xz-plane is :
d = 1 unit .
So , equation of circle with center C and radius 1 units is :
[tex](x-1)^2+(x+1)^2+(z-6)^2=1^2\\\\(x-1)^2+(x+1)^2+(z-6)^2=1[/tex]
Hence , this is the required solution .

Your correct answer is -81/10
Step-by-step explanation:
[tex]\frac{5}{100}- (8.1 + \frac{5}{100})[/tex]
= [tex]\frac{1}{20} - (8.1 + \frac{5}{100})[/tex]
= [tex]\frac{1}{20} - (8.1 + \frac{1}{20})[/tex]
= [tex]\frac{1}{20} -\frac{163}{20}[/tex]

Prove that root 7 is an irrational number.
Answer: Root 7 would equal 2.64575131106 and would go on forever.
Step-by-step explanation: It isn't one of the perfect squares. For example, the first 10 perfect square are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Answer:
it is an irrational number and here is why
Step-by-step explanation:
So think of square root as it's answer is something that you you multiply its self by its self and you get that answer. Ex: 8 x 8 = 64 square root of 64 is 8. So in that case there is nothing you can exactly multiply by itself to get 7 so in that case it's a decimal or an irrational number.

Solve for x: 3x+2=11
Answer:
X= 3
Step-by-step explanation:
To solve this, you must first subtract 2 from 11, to get the 3x isolated.
You'll then have 3x=9, but the x is not alone, so you subtract the 3 from both sides. This leaves you with 3
the value of x will be 3 for the given function 3x+2=11.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Given a function 3x+2=11
Simplifying the function:
=> 3x + 2 = 11
subtract by 2
=> 3x +2 - 2 = 11-2
=> 3x = 9
divide by 3 into both sides
=> x = 3
Therefore, the value of x will be 3 for the given function.

21. Chandra is retiling her bathroom floor. Each tile is in the shape of a
square, and is 6.5 inches long. How many square inches does one tile
cover? *
WILL MARK AS BRAINLIEST
Answer:
42.25 square inches
Step-by-step explanation:
the formula for area of a square is length x width
a square has four equal sides
so the length and width of the square are 6.5
so you would multiply 6.5 by itself: 6.5x6.5=42.25
so the tile overs 42.25 sq inch
solve for n
8+8+n-4=3n-2n
Answer:
No solution
Step-by-step explanation:

12+ n = 3n-2n
3n-2n
12+n3n-2n
subtract n on both sides
12=0n
