Answer:
[tex]width=12[/tex]
Step-by-step explanation:
The formula for the area of a rectangle:
[tex]Area=length*width[/tex]
Insert the known values:
[tex]180=15w[/tex]
Solve for w. Isolate the variable by dividing both sides by 15:
[tex]\frac{180}{15}=\frac{15w}{15} \\\\12=w[/tex]
w is equal to 12, so the width of the rectangle is 12 cm.

For the function p defined by p(m) = 2m2 - 4m +3, find p(-2).
Answer:
p(m) = 2m² - 4m +3
p(-2) = 2(-2)² - 4(-2) + 3
= 2 × 4 - 4 × (-2) + 3
= 8 + 8 + 3
= 16 + 3
= 19
The value of p(-2) of function p(m) = 2m² - 4m +3 is 19.
What is function?The function is defined as mathematics expression defines a relationship between one variable and another variable. When we say that a variable quantity y is a function of a variable quantity x, we indicate that y depends on x and that value of x determines what value of y will be. This relationship can be expressed as follows: y = f (x)
What is quadratic expression?The quadratic expression is defined as an expression containing the highest power of a variable is two.
For the function p defined by p(m) given as :
p(m) = 2m² - 4m +3,
To determine the value of p(-2).
p(m) = 2m² - 4m +3,
Substitute the value of m = -2 in the function,
p(-2) = 2(-2)² - 4(-2) +3,
p(-2) = 2(4) + 8 +3,
p(-2) = 8 + 11
p(-2) = 19
Hence, the value of p(-2) is 19.

If 3x+2=7(3-x), find the value of 26-x-4
Answer:
20.1
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, distribute 7 to all terms within the parenthesis:
7(3 - x) = (7 * 3) + (7 * -x) = 21 + -7x = 21 - 7x
3x + 2 = 21 - 7x
Isolate the variable, x. Subtract 2 and add 7x to both sides:
3x (+7x) + 2 (-2) = 21 (-2) - 7x (+7x)
3x + 7x = 21 - 2
10x = 19
Divide 10 from both sides:
(10x)/10 = (19)/10
x = 19/10 = 1.9
Plug in 1.9 for x in the expression given:
26 - x - 4 = 26 - 1.9 - 4
26 - 1.9 = 24.1
24.1 - 4 = 20.1
20.1 is your value.

What is the volume of a certain cube? (1) The sum of the lengths of the edges of the cube is 36. (2) The surface area of the cube is 54.
Answer:
(1) The sum of the lengths of the edges of the cube is 36.
A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3
Volume = 3*3*3 = 27
(2) The surface area of the cube is 54.
A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)
6s^2 = 54
s = 3
Volume = 3*3*3 = 27
Step-by-step explanation:
All you need to uniquely define a cube is any one measurement - length of a side/edge, area of a surface, volume etc. If you have any one of them, you can uniquely determine the others. So each statement alone is sufficient here.
To show how,
(1) The sum of the lengths of the edges of the cube is 36.
A cube has 12 equal edges. Sum = 36. Length of each edge = 36/12 = 3
Volume = 3*3*3 = 27
(2) The surface area of the cube is 54.
A cube has 6 identical faces. Area of each face = s^2 (s is the length of the side)
6s^2 = 54
s = 3
Volume = 3*3*3 = 27
if 3 divide a profit of rs 72,000 at end of the year according to the ratio of 2:3:4 of their investment how much did they receive
Step-by-step explanation:
Hey, there!!
See explanation in picture.
They receive 16000, 24000 and 32000 as per the ratios 2:3:4.
let x be a common factor,
Then,
2x+3x+4x =72000
sum them,
9x= 72000
x = 72000/9
=8000
Therefore, x= Rs. 8000.
2x= 8000×2 = Rs.16000
3x= 3×8000= Rs.24000
4x= 4×8000= Rs. 32000
You just need to put common factor on the ratios and then sum up them to get the value.

Let ∠BOC=x+3, ∠AOB=4x−7, and ∠AOC=21. Solve for x.
Answer:
5Step-by-step explanation:
Given the following angles ∠BOC=x+3, ∠AOB=4x−7, and ∠AOC=21, the expression is true about the angles;
∠AOC = ∠BOC+∠AOB
Substituting the given values into the expression, we will have;
21 = x+3+4x-7
collect the like terms
21 = x+4x+3-7
21 = 5x-4
Add 4 to both sides
21+4 = 5x-4+4
25 = 5x
Divide both sides by 5
5x/5 = 25/5
x = 5
Hence the value of x is 5
The Haas Door Co. produces truck dock door seals. Their 9' × 10' seal costs $280 to produce. The mark-up rate is 75% of the cost to produce. What is the retail price?
Answer:
$490 is the retail price
Step-by-step explanation:
75% = [tex]\frac{3}{4}[/tex]
[tex]\frac{280}{4} = 70[/tex]
[tex]70(3)=210[/tex]
[tex]280+210=490[/tex]
The retail price will be; 490 dollar.
What is Markup and Markdown?Markup is the amount that will be increased in the original price of the considered thing.
Markdown is the amount that will be decreased from the original price of the considered thing.
Think of "up" and "down" as increasing and decreasing prices respectively.
We are given that Haas Door Co. produces truck dock door seals. Their 9' × 10' seal costs $280 to produce.
The mark-up rate = 75% of the cost to produce.
Retail price = cost price + 75 % of cost price
Therefore,
Retail price = 280 + 75 % of 280
Retail price = 280 + 0.75 x 280
Retail price = 280 + 210
Retail price = 490
Thus, retail price is $ 490

A number has the property that its square is equal to 84 more than five times the number. Enter all numbers that have this property.
Answer:
The numbers for which the given property hold true are 12 and -7
Step-by-step explanation:
Let the number be [tex]x[/tex].
As per the given statement:
Square of the number ([tex]x^{2}[/tex]) is 84 more than five times of the number ([tex]5x+84[/tex]).
Writing in the equation form:
[tex]x^{2} =5x+84[/tex]
To find:
All the numbers for which above equation holds true.
Solution:
[tex]x^{2} =5x+84[/tex]
Let us solve the above equation by rearranging the terms and then let us find the roots of the equation.
It is a quadratic equation(i.e. maximum power of [tex]x[/tex] is 2) so it will have 2 solutions i.e. 2 values of [tex]x[/tex] for which the above equation will hold true.
[tex]x^{2} -5x-84=0[/tex]
Let us factorize the equation.
[tex]\Rightarrow x^{2} -12x+7x-84=0\\\Rightarrow x(x -12)+7(x-12)=0\\\Rightarrow (x+7)(x-12)=0\\\Rightarrow \bold{x=12, -7 }[/tex]
So, the numbers for which the given property hold true are 12 and -7.

Momo has $4.05 in dimes and quarters. If she has 5 more quarters than dimes,
how many of each does she have? Show your work and write a complete
sentence answer
Answers:
8 dimes13 quarters==================================================
Work Shown:
$4.05 = 405 cents
d = number of dimes
q = number of quarters
q = d+5 since she has 5 more quarters compared to dimes
10d = value in cents of all the dimes
25q = value in cents of all the quarters
10d+25q = total value in cents = 405
10d+25q = 405
10d+25(d+5) = 405
10d+25d+125 = 405
35d+125 = 405
35d = 405-125
35d = 280
d = 280/35
d = 8
She has 8 dimes
q = d+5 = 8+5 = 13
She also has 13 quarters
-------------------------
1 dime = 10 cents
8 dimes = 80 cents (multiply both sides by 80)
1 quarter = 25 cents
13 quarters = 325 cents (multiply both sides by 13)
8 dimes + 13 quarters = 80 cents + 325 cents = 405 cents
This converts back to $4.05, which confirms our answers.
An urn contains white and red balls. Four balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn. What is the probability that all balls drawn from the urn are red
Answer:
[r/(w + r)]^4
Step-by-step explanation:
The numbers of the different balls are not given, but here is the solution.
Let w = number of white balls.
Let r = number of red balls.
The total number of balls is w + r.
All drawings have the same probability since there is replacement.
Each drawing has the following probability of drawing a red ball:
p(red) = r/(w + r)
Since there are 4 drawings, and they are all independent events, the overall probability is the product of the individual probabilities.
p(4 red balls in 4 drawings) = [r/(w + r)]^4
To find an actual number, replace w and r with the correct numbers and evaluate the expression.
