A 50-foot flagpole near an office building casts a shadow
that is 12.5 feet long. At the same time, the office building
casts a shadow that is 50 feet long. How tall is the office
building?
Step-by-step explanation:
Here are some hints: "At the same time,"means you need to set up a proportion (two ratios equal each other).
The shadow is always on the ground.
A person and a flagpole always stands up straight, like a wall (vertical height)
Underline key words and numbers. Draw a picture for sure.

Since it is easier to work with one type of measurement, change the person's height to feet only. The person is 5feet, 6inches Note: 12 inches= 1 foot, so 6 inches= 1/2 a feet and 6 inches= .5 feet
a company’s stock was selling at 35$ a share. a month later it was selling at 14$ a share. what is the percent loss?
Answer:
60%
Step-by-step explanation:
its right
If a company’s stock was selling at 35$ a share. a month later it was selling at 14$ a share then the percent of loss is 60%.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that a company’s stock was selling at 35$ a share.
After a month later it was selling at 14$ a share.
We need to find the percent of loss.
Original share price=35
new share price=14
We calculate the percentage by finding the difference and dividing the difference with the original share price.
35-14/35
0.6
Now multiply this 0.6 with 100 as it is a hundredth part.
0.6×100
60%
Hence, if a company’s stock was selling at 35$ a share. a month later it was selling at 14$ a share then the percent of loss is 60%.

Use substitution to find an exponential function, y= a - b" that passes through
(2, 16) and (5, 1.024).
Answer:
[tex]y = 4^x[/tex]
Step-by-step explanation:
Given
[tex](2,16)[/tex]
[tex](5,1,024)[/tex]
Required
Determine the exponential function [tex]y = a.b^x[/tex]
In [tex](2,16)[/tex]
[tex]x=2[/tex] and [tex]y = 16[/tex]
Substitute these values in [tex]y = a.b^x[/tex]
[tex]16 = a.b^2[/tex] --- (1)
In [tex](5,1,024)[/tex]
[tex]x = 5[/tex] and [tex]y = 1024[/tex]
Substitute these values in [tex]y = a.b^x[/tex]
[tex]1024 = a.b^5[/tex] --- (2)
Divide (2) by (1)
[tex]\frac{1024}{16} = \frac{a.b^5}{a.b^2}[/tex]
[tex]\frac{1024}{16} = \frac{b^5}{b^2}[/tex]
[tex]64 = \frac{b^5}{b^2}[/tex]
Apply second law of indices
[tex]64 = b^{5-2[/tex]
[tex]64 = b^3[/tex]
Express 64 as an exponent of 3
[tex]4^3 = b^3[/tex]
[tex]4 = b[/tex]
[tex]b = 4[/tex]
Substitute 4 for b in (1)
[tex]16 = a.b^2[/tex]
[tex]16 = a * 4^2[/tex]
[tex]16 = a * 16[/tex]
[tex]16 = 16a[/tex]
Solve for a
[tex]a=\frac{16}{16}[/tex]
[tex]a = 1[/tex]
Substitute 1 for a and 4 for b in [tex]y = a.b^x[/tex]
[tex]y = 1 * 4^x[/tex]
[tex]y = 4^x[/tex]
The exponential function is given by y = 100(0.4)ˣ
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the factor.
At point (2, 16):
16 = ab² (1)
At point (5, 1.024):
1.024 = ab⁵ (2)
Dividing equation 2 by equation 1:
b³ = 0.064
b = 0.4
16 = a(0.4)²
a = 100
The exponential function is given by: y = 100(0.4)ˣ

You want to know how much lager a full sized candy bar is to see if you are getting a good price.
Step-by-step explanation:
A pool is in the shape of a rectangular prism. On Monday, water was pumped out of the pool at a constant rate, starting at 12:00 p.m. At 12:15 pm, the water in the pool was 45 inches deep. At 12:25 p.m., the water in the pool was 41 inches deep. Write an equation that represents y, the depth of the water (in inches), after x minutes.
Answer:
y = 51-0.4x
Step-by-step explanation:
From the question, we can see that the amount of water left in the pool was 45 inches deep within 12:15-12:00 = 15 minutes
However, within 10 minutes there was a loss of 45-41 = 4 inches
So what this means is that per minute, the amount of loss expected is 4 inches/10 minutes = 0.4 inches per minute
what we are saying is that a loss of 4 inches depth of water is needed per minute
So we want to write an equation, representing the depth after x minutes
So what we have here is that the total inches at present will be;
45 + 0.4(15) = 45 + 6 = 51 inches
The pool was 51 inches deep initially before the pumping out began
That will be;
y = 51-0.4x
where is the depth and x is the number of minutes
Answer:
24 inches

Answer:
∠ EFG = 83°, ∠ GCE = 97°
Step-by-step explanation:
Since FE and FG are tangents to the circle then
∠ FGC and ∠ FEC are right angles
The sum of the angles in quadrilateral CEFG = 360°
Sum the 4 angles and equate to 360
3x + 11 + 90 + 5x - 23 + 90 = 360, that is
8x + 168 = 360 ( subtract 168 from both sides )
8x = 192 ( divide both sides by 8 )
x = 24
Thus
∠ EFG = 3x + 11 = 3(24) + 11 = 72 + 11 = 83°
∠ GCE = 5x - 23 = 5(24) - 23 = 120 - 23 = 97°

Shaq invested $900 into a savings account that pays annual simple interest. At the end of 9 years, he earned $461.70 in interest. What is the interest rate on the savings account? Round to the nearest tenth of a percent.
Answer:
Interest = $900 * x * 9 years with "x" = interest rate
If interest = 461.70 then
461.70 = 900 * 9 * x
x = 461.70 / 8,100
x = interest rate = .057 = 5.7%
Double Check
Interest rate of 5.7 per cent equals
.057 * 900 = $51.30 per year
Nine Years = 9 * 51.30 equals 461.70
So, it's correct!!!

What is the inverse of f(x) = sqft x+ 3
Answer:
[tex]f^{-1} (x)=x^{2} -3[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\sqrt{x+3}[/tex]
We can find the inverse function by exchanging x and y, and then solve for y.
[tex]y=\sqrt{x+3}[/tex]
Replace x with y.
[tex]x=\sqrt{y+3}[/tex]
square both sides
[tex]x^2=y+3[/tex]
[tex]y=x^2-3[/tex]
Hence,
[tex]f^{-1} (x)=x^{2} -3[/tex]
