The length of the shadow of a 4 ft stick can be found by comparing its shadow to the shadow of a 32 ft tall building. The building had a shadow 6 ft long. How long would the stick's shadow be at that time?
The shadow of the 4 feet stick is 3/4 feet or 0.75 feet.
It is a question of ratio and proportion.
It is given in the question that the 32 feet tall building had a shadow 6 feet long.
We have to find the length of the shadow of a 4 ft stick.
Let the length of the shadow of a 4 ft stick be x.
We know that length and shadow of a 4 feet stick and a 32 feet building will be in proportion.
Hence, we can write,
Length of building/Length of stick = shadow of building/shadow of stick
32/4 = 6/x

Write down equation of lines l and m
Step-by-step explanation:
I assume you need the slope-intercept form
y = ax + b
"a" is the slope of the line, "b" is the y- intercept (the y-value when x = 0).
the slope is the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
for l we go from (5, 20) to (8, 80) and get
x changes by +3 (from 5 to 8)
y changes by +60 (from 20 to 80)
the slope is therefore
+60/+3 = 20/1 = 20 = a
so, we have
y = 20x + b
the y- intercept looks to be -80, but to be sure we use a point (e.g. 5, 20)
20 = 20×5 + b = 100 + b
b = -80
yes, the equation is
y = 20x - 80
for m we go from (5, 20) to (8, -40) and get
x changes by +3 (from 5 to 8)
y changes by -60 (from 20 to -40)
the slope is
-60/+3 = -20/1 = -20
we have therefore
y = -20x + b
we use the same trick for b as before
20 = -20×5 + b = -100 + b
b = 120
and our full equation is
y = -20x + 120

How to use equation to solve a problem?The purchase of the large TV including finance charges is 1615 dollars . A down payment of 400 dollars was paid. The remainder was paid in 18 monthly instalment payment.
Therefore, using equation,
let
x = amount paid each month
The monthly payment can be found as follows:
1615 = 400 + 18x
1615 - 400 = 18x
1215 = 18x
divide both sides by 18
x = 1215 / 18
x = 67.5 dollars
Therefore,

What is Percent?Percentages are basically fractions with a denominator of 100. We use the percent symbol (%) beside a number to indicate that it is a percentage. A percentage is a relative value that represents the hundredth part of any quantity. One percent (symbolized 1%) is one hundredth part; thus, 100 percent represents the entire amount.
What is method to calculate the percent?To manually calculate percentages, follow these steps:
1. Determine the number's initial format to be converted to a percentage.
The decimal or fraction format of the number to be converted to a percentage can be used. The next mathematical process to be performed on the number will be determined by the initial format.
2. Perform a mathematical calculation on the number to be converted to a percentage.
If the number to be converted to a percentage is a decimal number, such as 0.57, you may not need to proceed to the next step.
3. Multiply the result by 100.
To convert a decimal number, such as 0.57, to a percentage, simply multiply it by 100.

A bank deposit paying simple interest grew from an initial amount of $1100 to $1265 in 6 months. Find the interest rate.
If the bank deposit paying simple interest grew from an initial amount of $1100 to $1265 in 6 months, then the interest rate is 30%
The initial amount = $1100
The final amount = $1265
So simple interest = 1265-1100
= $165
Time period = 6 months = 6/12 years
We know
Simple interest I = P×r×t
Where P is the initial amount
r is the interest rate
t is the time period
Substitute the values in the equation
165 = 1100×r×(6/12)
165 = 550×r
r = 165/550
r = 0.3
r = 30%
Hence, If the bank deposit paying simple interest grew from an initial amount of $1100 to $1265 in 6 months, then the interest rate is 30%

Using the binomial distribution, the probabilities are given as follows:
1) Three girls in a family of five children: 0.3125 = 31.25%.
2) At least two boys in a family of seven children: 0.9375 = 93.75%.

4) At least two left-handed people in a group of 7: 0.1497 = 14.97%.
5) At least five of them have the same birth date: 0%.
What is the binomial distribution formula?The formula for the probability of x successes is:
[tex]P(X = x) = C(n,x).p^{x}.(1-p)^{n-x}[/tex]
[tex]C(n,x) = \frac{n!}{x!(n-x)!}[/tex]
The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.Item 1A children is equally as likely to be a boy or a girl, hence the parameters are given as follows:
n = 5, p = 0.5.
The probability is P(X = 3), hence:
P(X = 3) = C(5, 3) x (0.5)³ x (0.5)² = 0.3125 = 31.25%.
Item 2The parameters are:
n = 7, p = 0.5.
The probability of at least two boys is:
P(X >= 2) = 1 - P(X < 2).
In which:
P(X < 2) = P(X = 0) + P(X = 1).
Then:
P(X = 0) = (0.5)^7 = 0.0078.P(X = 1) = C(7,1) x (0.5)^7 = 0.0547.P(X < 2) = P(X = 0) + P(X = 1) = 0.0078 + 0.0547 = 0.0625.P(X >= 2) = 1 - P(X < 2) = 1 - 0.0625 = 0.9375 = 93.75%.Item 3This one is simple probability, number of desired outcomes divided by the number of total outcomes.
When 4 dice are thrown, we have that:
There are 140 outcomes with a sum of 15.There are 6^4 total outcomes.Hence the probability is:
p = 140/(6^4) = 0.1080 = 10.80%.
Item 4The parameters are:
n = 7, p = 0.1.
Hence, similarly to item 2:
P(X = 0) = (0.9)^7 = 0.4783.P(X = 1) = C(7,1) x (0.1) x (0.9)^6 = 0.3720.P(X < 2) = P(X = 0) + P(X = 1) = 0.4783 + 0.3720 = 0.8503.P(X >= 2) = 1 - P(X < 2) = 1 - 0.8503 = 0.1497 = 14.97%.Item 5The parameters are:
n = 75, p = 1/365 = 0.0027.
Then the probability is:
P(X >=5) = 1 - P(X < 5).
In which:
P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4).
Using a calculator, it is found that P(X < 5) = 1, hence the probability is of 0%, as P(X >=5) = 1 - 1 = 0.

y=-x^2+16x-55
Step-by-step explanation:
Since two intercepts are given (the two x-intercepts in this case), we should probably use intercept form.
y=a(x-b)(x-c)
plug in the intercepts which are 5 and 11 in this case
y=a(x-5)(x-11)
to solve for a, use the remaining point and set x to 6 and y to 5. we can do this because (6,5) is given to us as a solution of one of the points on the graph.
5=a(6-5)(6-11)
5=a*(-5)
a=-1
so, the equation should be:
y= - (x-5)(x-11)
expand the parentheses to get:
y=-x^2+16x-55

From the graph of the function, it's behavior on the intervals is given as follows:
Increasing: x >0.Decreasing: x < 0.When a function is increasing?Looking at the graph, we get that a function f(x) is increasing when it is "moving northeast" along the xy-plane, that is, to the right and up on the graph, meaning that when x increases, y increases.
Hence, from the graph of the function, it is increasing for the values to the right of x = 0, that is, on the interval x > 0.
When a function is decreasing?Looking at the graph, we get that a function f(x) is decreasing when it is "moving southeast" along the xy-plane, that is, to the right and down on the graph, meaning that when x increases, y decreases.
Hence, from the graph of the function, it is decreasing for the values to the left of x = 0, that is, on the interval x < 0.

Fred, Max, and Ken went trick or treating. Fred had 2 bags of candy with 45 pieces each. Max had 3 bags with 20 pieces each and Ken had 4 bags of candy with 15 pieces each. The boys combined the candy and shared it among 12 people. How much candy is leftover?
Answer:
6 pieces of candy will be left.
Step-by-step explanation:
45×2 = 90
20×3 = 60 +
15×4 = 60
Ttl. of candies= 210
Candies ÷ people
210 ÷ 12 = 17.5
17-12= 5.5 (round to the tenth) 5.5-> 6
210-6= 204
you'll get 6 as the difference which is your answer.

Step-by-step explanation:
Trapezoid W’X’Y’Z’ is the image of trapezoid W’ X’ Y’ Z’ under a dilation though point c
The scale factor used in the dilation through point c is 3/4.
Using the Scale Factor, shapes in various dimensions can be scaled. In geometry, we examine a wide variety of two- and three-dimensional geometrical forms.
Comparing figures with similar appearances but different scales or measures is possible using the scale factor. Take into account two circles that resemble one another but could have various radii. The scaling factor shows how much a figure has grown or shrunk from its starting point.
Any original shape can be designed as an extended or condensed version by using a scaling factor. In the equation y = Kx, K is the scaling factor for x.
The scale factor formula is provided by:
dimensions of the first form x scale Factor = Dimension of new shape
Scale factor equals Dimension of New Shape divided by Dimension of Original Shape
Given, dimension of trapezium WXYZ = 8 m
Dimension of trapezium W'X'Y'Z' = 6 m
Using above literature and necessary assumptions:
WXYZ * scale factor = W'X'Y'Z'
Therefore, scale factor = W'X'Y'Z'/WXYZ ⇒ scale factor = 6m/8m = 3/4
Thus, the scale factor is 3/4.
