Answer:
Width is 5
Step-by-step explanation:
Set up an equation
12x=60
divided both sides by 12
answer is 5
The width is 5
to check your answer multiply it by the length
12*5=60
Check Check
Answer:
60÷12=5 so the width is 5 if the length is 12.

Complete the set of data with one value so that the mean of the data is 24. 26, 35, 10, 18, 15, 37, 25, 20, 15,
Answer:
39
Step-by-step explanation:
So there are 9 values. (1 to be added). First we add them all up. And we need to add another value. So the mean is all of the values added up, divided by the number of numbers. If we add another value, then there'll be 10 values. 24x10 is, of course, 240. If you add all of the given values, you get 201. And we can easily create the equation, x+201=240, and x, or the missing value, is obviously 39.
A right circular cylinder has a volume of 1296 cubic inches if the radius of the cylinder is divided by 12 what be the volume in cubic inches of the smaller cylinder
Answer:
Step-by-step explanation:
A right circular cylinder has a volume of 1296 cubic inches
The volume of a cylinder = πr²h
Step 1
We find the radius
1296 inches = πr²h
r² = 1296/π ×>h
if the radius of the cylinder is divided by 12 what be the volume in cubic inches of the smaller cylinder

Can someone plz help me with this one problem plzzzzz!!!!
Answer:
No.
Step-by-step explanation:
In order for this equation to be true, either the 8 would have to be negative or the 11.
when f(x) is replaced with
f(x)+k, the graph that results is shown below
K=__?
Answer:
k = 6
Step-by-step explanation:
Parent function of the given graph → f(x) = (x - 1)²
If the parent function is shifted 6 units up.
Equation of the translated function will be → g(x) = (x - 1)² + 6
g(x) = f(x) + 6
Therefore, k = 6 will be the answer.
Please Help!!!!! You have twice as many nickels as pennies. you have $1.10. how many of each coin do you have? Solve each problem using a system of equations.
Answer:
Step-by-step explanation:
n=2p
p+5n=110, using n found above makes this become
p+5(2p)=110
p+10p=110
11p=110
p=10, since n=2p
n=2(10)
n=20
So there are 10 pennies and 20 nickels.

a) The value of the equation is A = ( x - 1 ) ( x² + 3 )
b) The value of the equation is B = ( x⁴ - 6x² + 10 ) ( x² - 4 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
a)
The equation is A = x³ + 3x - x² - 3
On simplifying the equation , we get
A = x³ - x² + 3x - 3
A = x² ( x - 1 ) + 3 ( x - 1 )
On factorizing the equation , we get
A = ( x² + 3 ) ( x - 1 )
b)
The equation is B = ( x² - 3 )³ - ( 2 - x² )² + 3 ( x² - 3 )
On simplifying the equation , we get
B = ( x² - 3 )³ - ( x⁴ - 2x² - 2x² + 4 ) + 3 ( x² - 3 )
On further simplification , we get
B = ( x² - 3 )³ - x⁴ + 4x² - 4 + 3x² - 9
B = ( x² - 3 )³ - x⁴ + 7x² - 13
On factorizing the equation , we get
B = ( x - 2 ) ( x⁵ + 2x⁴ - 6x³ - 12x² + 10x + 20 )
B = ( x - 2 ) ( x + 2 ) ( x⁴ - 6x² + 10 )
And , on further simplification , we get
B = ( x² - 4 ) ( x⁴ - 6x² + 10 )
Hence , the equation is B = ( x² - 4 ) ( x⁴ - 6x² + 10 )

Answer:
(1) [tex]x = -4[/tex] (2) [tex]x = 7[/tex]
Step-by-step explanation:
From the first equation:
[tex]2(x + 3) = x - 4\\\implies x = 2(x + 3) + 4\\\implies x = 2x + 6 + 4\\\implies x = 2x + 4\\\implies -4 = 2x - x\\\implies x = -4[/tex]
From the second equation,
[tex]4(5x - 2) = 2(9x + 3)\\\implies 20x - 8 = 18x +6\\\implies 20x - 18x - 8 -6 = 0\\\implies 2x -14 = 0\\\implies 2x = 14\\\implies x = \frac{14}{2} = 7[/tex]

One morning at a zoo, there were 165 adults and children who paid to enter. The zoo collected $1,440 from admission fees. The price of admission is $10 for an adult and $7 for a child. How many children were admitted to the zoo?
Answer:
number of children admitted to the zoo=70
let adult =a
let children=c
a+c=165........equation 1
10a+7c=1440.......equation 2
a=165-c........equation 3
substitute equation 3 in equation 2
10a+7c=1440
10(165-c)+7c=1440
1650-10c+7c=1440
-10c+7c=-210
-3c=-210
c=70
Therefore children =70
does 20, 40, 30 form a pythagorean triple
Answer:
Step-by-step explanation:
If it is a Pythagorean Triple the hypotenuse and the legs of a right triangle will all be integer values where
c^2=a^2+b^2
In this case, this isn’t even a right triangle as
20^2+30^2=40^2
400+900=1600
1300!=1600
because 1300 does not equal 1600 this is not a Pythagorean Triple.

Answer:
A triangle with angles measuring 55°, 60°, 65° degrees
Step-by-step explanation:
Two obtuse angles means two angles over 90°
The sum of all angles in a triangle are 180°
90°+90° itself is 180°, so we cant have two angles greater than 90°
Two right angles means 90° and 90° which is 180°, not possible
55°+60°+65° = 180° so it is possible.

9x−17=3x+7 Solve for x
−7b−1=−5(b+3) Solve for b
Answer:
x=4 b=-4/3
Step-by-step explanation:
for b you simplify both sides of the equation, and then you get -7b - 1 = 5B + 15 then you subtract 5 from both sides which gets you to -12b - 1 = 15 then you divide both sides by negative 12 which would be negative 12 b - -12 = 16-12 which gives you the answer of -4/3.
for x you would subtract 3x from both sides which gets you to 6x - 17 = 7 and then you would add 17 to both sides which would give you 6X = 24 and then you would divide both sides by 6 which would give you x = 4

The difference between two numbers is 3. The sum of the same tow numbers is 13. What is the
product of the two numbers?
Answer: 40
Step-by-step explanation:
Let the two numbers be a and b.
Therefore,
a - b = 3 ....... i
a + b = 13 ....... ii
From equation I, a = 3 + b
Put a = 3+b into equation ii
a + b = 13
3 + b + b = 13
3 + 2b = 13
2b = 13 - 3
2b = 10
b = 10/2
b = 5
Since a = 3 + b
a = 3 + 5
a = 8
The product of the numbers will be:
= 8 × 5
= 40
