If a 40 ft tall flagpole casts a 256 ft long shadow then how long is the shadow that a 6 ft tall woman casts?
feet
Answer:
38.4 ft
Step-by-step explanation:
Basically, draw out your two Situations like I have did.
Then find the scale factor by doing 6/40.
Multiply the SF by 256 to get X, or the shadow of the woman.

The amount of television viewed byâ today's youth is of primary concern to Parents Against Watching Televisionâ (PAWT). 300 parents of elementaryâ school-aged children were asked to estimate the number of hours per week that their child watches television. The mean and the standard deviation for their responses were 12 and 3â, respectively. PAWT constructed aâ stem-and-leaf display for the data that showed that the distribution of times was aâ symmetric, mound-shaped distribution. Give an interval where you believe approximatelyâ 95% of the television viewing times fell in the distribution.
a. less than 9 and more than 15 hours per week
b. between 3 and 21 hours per week
c. between 6 and 18 hours per week
d. less than 18
Answer:
Option C. between 6 and 18 hours per week
Step-by-step explanation:
We are given that distribution of times is symmetric and mound shaped and this implies that data is normally distributed.
We also know that in the normal distribution the 95% of data lies within 2 standard deviations i.e. mean± 2*standard deviation.
So, 95% of the television viewing times falls in interval
mean± 2*standard deviation
12±2*3
12±6
[6,18]
Thus, [6,18] is an interval where you believe approximately 95% of the television viewing times fell in the distribution.

The answer is 72
Step-by-step explanation:
The formula to find the area of a trapezoid
[tex]A= \frac{1}{2}h(b_{1} + b_2{} )[/tex]
First, we can add the bottom base together
5 + 8 + 3 = [tex]16_{2}[/tex]
We know that the height of the trapezoid is 6 and base1 is 8
[tex]A= \frac{1}{2}6(16 + 8)[/tex]
[tex]A=\frac{1}{2}6(24)[/tex]
[tex]A=3(24)[/tex]
[tex]A=72[/tex]
OR
Find the area of the two triangles
[tex]A=\frac{1}{2}5(6)\\\\A=5(3)\\\\A=15\\\\[/tex][tex]A=\frac{1}{2}3(6)\\\\A=3(3)\\\\A=9\\[/tex]
15 + 9 = 24
For the area of the rectangle
6 x 8 = 48
48 + 24 = 72

Answer:
-1 and 3
Step-by-step explanation:
The roots of the quadratic function can be determined by [tex]f(x')=0[/tex] where x' is the roots of the quadratic function. In that graph, x = -1 and x = 3 makes the value of f(-1) = 0 and f(3) = 0. So, x = -1 and x = 3 are the roots of the f(x).

Kiara has already written 37 pages, and she expects to write 1 page for every additional hour spent writing. How many hours will Kiara have to spend writing this week in order to have written a total of 50 pages?
Answer:
13 hours
Step-by-step explanation:
Since Kiara has already written 37 pages she only needs 13 more to get to 50 pages. If she takes one hour per page then it will take her 13 hours to write 13 pages.
12. You purchase a new computer for $2,100. The function f(x) = 2100(.5)* gives the value of the

each year, where x is the number
of years since the computer was purchased. What is
the value of the computer after four years?
A. $1050
B. $525
C. $262.50
D. $131.25
Answer:
I think it's C but I never did this before so don't trust me
Step-by-step explanation:
2100 * 5 = 1050 and I divided 1050 by 4 which gave me $262.50
A frame around a rectangular family portrait has a perimeter of 138 inches. The length is nine more than three times the width. Find the length and width of the frame.
Given :
Perimeter of the frame is 138 inches.The length is nine more than three times the width⠀
To Find :
The Length and width of the frame .⠀
Solution :
We know that,
[tex]\qquad{ \bold{ \pmb{2(Length + Breadth ) = Perimeter_{(rectangle)}}}}[/tex]
Let's assume the width of the rectangle as x inches. Then the length will become (3x + 9).
⠀
Now, Substituting the given values in the formula :
[tex]\qquad \dashrightarrow{ \sf{2(3x + 9 + x )= 138}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{2(4x + 9 )= 138}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{8x + 18= 138}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{8x = 138 - 18}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{8x = 120}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{x = \dfrac{120}{8} }}[/tex]
[tex]\qquad \dashrightarrow{ \bf \: x = 15}[/tex]
⠀
Therefore,
[tex]\qquad { \pmb{ \bf{ Width _{(frame)} = x = 15 \: inches}}}\:[/tex]
[tex]\qquad { \pmb{ \bf{ Length _{(frame)} = (3x + 9) \: = 3(15) + 9 = 54 \: inches}}}\:[/tex]

Answer:
A(3, 3) and B(12, 6), C(16, -6)A(-10, 5) and B(12, 16), C(18, 4)Step-by-step explanation:
As the attached diagram shows, a perpendicular line from B intersects a choice of C only for B1(12, 6) and B2(12, 16). We note that there are only 3 choices of point C shown, instead of 4, so the question may be incomplete.
__
It seems easiest to graph the points and use a square (right-angle tool) to identify points C that may be appropriate.
It can also work to use a spreadsheet to do the slope calculations. You want to find a point C such that BC ⊥ AB, for a given AB pair. That is, the slope of BC is the negative reciprocal of the slope of AB.
The 2nd and 3rd C points listed make right angles with the 1st and 2nd AB pairs listed, respectively.

find the equation of a line passes through a point (0,4) and has a gradient of 2. leave your answer in the form y=mx+c
Answer:
y = 2x + 4
Step-by-step explanation:
the equation of a line in point- slope form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 2 and passes through point (0, 4 ) ⇒ c = 4
y = 2x + 4 ← equation of line
Answer:
y = 2x + 4
Step-by-step explanation:
General form of linear equation: y = mx + c
where m is the gradient and c is the y-intercept
Given gradient = 2
⇒ m = 2
⇒ y = 2x + c
y-intercept is when x = 0
Given (0, 4), so y = 4 when x = 0
⇒ c = 4
⇒ y = 2x + 4
