A vertical stick 12 m long casts a shadow 8 m long on the ground. At the same time a tower casts the shadow 40 m long on the ground. The height of the tower is : *
Answer:
60m tall
Step-by-step explanation:
Since this is a ratio problem and we are given 3 values and 1 unknown then we can use the Rule of Three to calculate the height of the tower which we will refer to as x. The Rule of Three simply multiplies the diagonal values and divides by the third value in order to get the missing unknown like so...
12m height <======> 8m shadow
x height <======> 40m shadow
(40m * 12m) / 8m = 60m height
Finally, we can see that the height of the tower is 60m tall.

Step-by-step explanation:
The average of four numbers 30.5. three of the numbers are 24.2, 14.5, 50.5
what is the fourth number?
Answer:
32.8
Step-by-step explanation:
The average is calculated as
average = [tex]\frac{sum}{count}[/tex]
let x be the fourth number, then
[tex]\frac{24.2+14.5+50.5+x}{4}[/tex] = 30.5 ( multiply both sides by 4 )
89.2 + x = 122 ( subtract 89.2 from both sides )
x = 32.8
Thus the fourth number is 32.8

Which one is right *Will make BRAINLEST*
Answer:
The correct answer is:
Option A: [tex](14.\frac{1}{7})\frac{2}{5}[/tex]
Step-by-step explanation:
Associative property is applied on three numbers which states that when two numbers are being added or multiplied the order of addition and multiplication doesn't matter i.e. the answer is same.
If a,b and c are three numbers then associative property for multiplication can be given as:
a.(b.c) = (a.b).c
The given expression is:
[tex]14(\frac{1}{7}.\frac{2}{5})[/tex]
Applying the associative property for multiplication we get
[tex](14.\frac{1}{7})\frac{2}{5}[/tex]
Hence,
The correct answer is:
Option A: [tex](14.\frac{1}{7})\frac{2}{5}[/tex]

(x-5) divided by (x^2+3x-40)
Answer:
1/ x +8
*The 1 over x + 8
Answer:
[tex]\frac{1}{x+8}[/tex]
Step-by-step explanation:
Here is your original equation:
[tex]\frac{x-5}{x^{2} +3x-40}[/tex]What we need to focus on is simplification, specifically simplifying the denominator. First, let's isolate the denominator (we'll get back to [tex]x-5[/tex] later):
[tex]x^{2} +3x-40[/tex]
Next, we take a look at -40. Our goal is to find what factors of 40 create a sum of 3 so we can separate the equation for polynomial division.
Let's begin building our expressions. We know that [tex]x^{2}[/tex] has an exponent of 2. When variables are multiplied, the exponents are added, meaning that [tex]x*x=x^{2}[/tex]. (Or [tex]x^{1} + x^{1} =x^{2}[/tex] , the 1s just don't show)
We can also see that -40 is a negative number. A negative multiplied by a positive makes a negative product, so we can also include one positive and one negative in each expression.
[tex]x^{2} +3x-40 = (x+)(x-)[/tex]
Next, let's look at the factors of 40:
1 and 40 2 and 20 4 and 10 5 and 8
Which of these factors can make a sum of 3? Remember that one number has to be positive and the other has to be negative!
[tex]8-5=3[/tex]In this instance, our positive number is 8 and our negative number is 5. They create the sum of 3 that we're splitting in [tex]3x[/tex]. Therefore, [tex]8(-5)=-40[/tex].
[tex]x^{2} +3x-40 = (x+8)(x-5)[/tex]Now let's go back to our original equation and substitute our old expression with the new one:
[tex]\frac{x-5}{(x+8)(x-5)}[/tex]Do you notice that the numerator and part of the denominator are equal? This means that they can cancel each other out! Think of it as a [tex]\frac{1}{1}[/tex].
[tex]\frac{x-5}{(x+8)(x-5)}[/tex] = [tex]\frac{1}{x+8}[/tex]Therefore, your simplified answer is [tex]\frac{1}{x+8}[/tex] !
Here's the whole process:
[tex]\frac{x-5}{x^{2} +3x-40} \\\\(x+?)(x-?)\\\\40:\\1, 40\\2, 20\\4, 10\\5, 8\\\\8-5=3 \\(8x-5x=3x)\\\\(x+8)(x-5)\\\\\frac{x-5}{(x+8)(x-5)}=\frac{1}{x+8} \\\\\frac{1}{x+8}[/tex]
To check your answer, confirm your expressions using the box method attached.
I hope this helps! If you have any more questions or concerns about the answer or the process, let me know!
La empresa Computec se dedica a la producción de calculadoras, donde el costo de producir cada una es de $120 y los costos fijos semanales son de $15000. Además, la empresa vende cada calculadora al precio de $20. ¿Cuántas calculadoras debe producir y vender la empresa para obtener una utilidad semanal de $16?
Answer:
Unidades a vender= 388
Step-by-step explanation:
Dada la siguiente información:
Costo variable unitario= $120
Costo fijo= $15,000
Precio de venta= $200
Utilidad deseada= $16,000 (supongo)
Para calcular el número de unidades a vender, tenemos que usar está formula:
Unidades a vender= (costo fijo +utilidad deseada) / contribucíon marginal
Unidades a vender= (15,000 + 16,000) / (200 - 120)
Unidades a vender= 388

Company C offers greatest total employment compensation since, it has least job expenses as compared to the other three and comparatively good gross pay. Therefore, option C is the correct answer.
What is the net pay?Net pay means take-home pay or the amount employees earn after all payroll deductions are subtracted from their gross pay.
Company A
Gross pay=$37,600, Paid insurance=$2800, Paid time off =$3,100, Job expenses = $1,200
Company B
Gross pay=$36,800, Paid insurance=$2,400, Paid time off =$3,600, Job expenses = $600
Company C
Gross pay=$38,100, Paid insurance=$2,100, Paid time off =$2,900, Job expenses = $300
Company D
Gross pay=$39,000, Paid insurance=$1,800, Paid time off =$2,500, Job expenses = $800
Company C offers greatest total employment compensation since, it has least job expenses as compared to the other three and comparatively good gross pay.
Wherever in all other cases that is in gross pay, paid insurance, paid off company C is not that much legging behind
Company D has greatest gross pay but has greatest expense also
Company A is at second position in paying but also at 2nd in expenses.
Company B is least payer but do not have least expenses.
Company C offers greatest total employment compensation since, it has least job expenses as compared to the other three and comparatively good gross pay. Therefore, option C is the correct answer.

If the width and length of a rectangle are both increased by 10%, by what percent does the area of the rectangle increase?
By what percent does the perimeter of the rectangle increase?
Answer:
10%
Step-by-step explanation:
We know Perimeter of rectangle
= 2 (Length + Width)
If width and length are increased by 10%
New length= L + 10/100L = (1.1) L
New width = W + 10/100W = (1.1) W
Perimeter = 2 [(1.1) L + (1.1) W]
Perimeter = 2 (1.1) (L + W)
Perimeter = (2.2) (L + W)
Increase in perimeter = 2.2 (L + W) - 2 (L + W)
The increase in Perimeter = 0.2 (L + W)
Percent increase
= 0.2 (L + W)/2 (L + W) × 100
= 0.2/2 × 100
= 0.1 × 100
= 10%

Write the equation for f(x)=x^2
But flipped over the x-axis, shifted 4 units down, and shifted 1 unit to the left.
Will give brainliest for best answer :) tysm! <3
Answer:
[tex]f^\prime(x)=-(x+1)^2-4[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=x^2[/tex]
And we want to write its equation after being: 1) Flipped over the x-axis, 2) shifted 4 units down, and 3) shifted 1 unit to the left.
To denote a flip over the x-axis, we multiply the function by -1. Hence:
[tex]f^\prime(x)=-x^2[/tex]
Is our function flipped over the x-axis.
To shift n units vertically, we simply add n to our function.
Since we are going 4 units downwards, we will add -4 to our function. Hence:
[tex]f^\prime(x)=-x^2-4[/tex]
Finally, to shift n units horizontally, we substitute our variable [tex]x[/tex] for [tex](x-n)[/tex].
Since we are shifting 1 unit to the left, n=-1. Hence, we will substitute [tex]x[/tex] for [tex](x+1)[/tex]. Therefore:
[tex]f^\prime(x)=-(x+1)^2-4[/tex]
So, our final function is:
[tex]f^\prime(x)=-(x+1)^2-4[/tex]
CJ earned a score of 75% on his math quiz each question on the quiz worth one points in CJ got 18 question correct how many questions were on the quiz
Answer: 24 questions
Step-by-step explanation:
Let the number of questions on the quiz be represented by x. This means that 75% of x equals 18. We need to calculate x. This will be:
75% × x = 18
75/100 × x = 18
0.75 × x = 18
0.75x = 18
x = 18/0.75
x = 24
The quiz has 24 questions.
