Step-by-step explanation:
In similar triangles, the corresponding sides will be in same ratio
[tex]2) \frac{x}{8}=\frac{30}{15}\\\\x =\frac{30}{15}*8\\\\x=2*8\\\x = 16[/tex]
[tex]3) \frac{x}{20}=\frac{12.8}{16}\\\\x = \frac{12.8}{16}*20\\\\x= \frac{128}{8}\\\\x = 16[/tex]
[tex]\frac{y}{10}=\frac{12.8}{16}\\\\y=\frac{12.8}{16}*10\\\\\\y=8[/tex]
[tex]4) \frac{x}{15}=\frac{8}{6.4}\\\\x=\frac{8}{6.4}*15\\x=18.75[/tex]
[tex]5) \frac{x}{12}=\frac{22.5}{9}\\\\x=\frac{22.5*12}{9}\\\\x= 30[/tex]
[tex]6)\frac{14}{8}=\frac{7}{4}\\\\\frac{12}{6}=\frac{2}{1}\\\\\frac{10}{5}=\frac{2}{1}[/tex]
As the ratio of corresponding sides are not proportion, these are not similar triangles
For a dilation with a scale factor less than 1, how do the angles and side lengths of the preimage relate to the angles and side lengths of the image?
A. Angle are proportional;side lengths are larger
B. Angles are proportional;side lengths are smaller
C. Angles are congruent;side lengths are larger
D. Angles are congruent; side lengths are smaller
The dilation of an image with a scale factor less than 1 will have the angle proportional to the preimage, and the side lengths have been smaller. Thus, option B) is correct.
The dilation factor has been the scale factor that has been used for the enlargement or reduction of the image. The images with a dilation factor of more than 1 enlarge, while the images with a dilation factor less than 1 shrinks.
The angle of the image with a scale factor less than 1 has been proportional as with shrinking, the angles have been reduced proportionally with the scale factor.
The reduction in scale factor from 1 will shrink the image. The shrinked image will be consist of a smaller size. So there has been a reduction in the side length of the image.
So, with the image with dilation of scale factor less than 1, the angles are proportional while the side length is smaller. Thus option B) is correct.

A circle with radius 4 meters
A circle with diameter 7 meters
A circle with circumference 24 meters
A circle with circumference 5 pi
Answer:
24 m
Step-by-step explanation:
it is 24metre ok......
The greatest circumference is 25.12 meters.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2πr.
The area of a circle is πr².
We have,
A circle with a radius of 4 meters.
Circumference.
= 2πr
= 2 x 3.14 x 4
= 25.12 meters
A circle with a diameter of 7 meters
Radius = 7/2 meters
Circumference.
= 2πr
= 2 x 3.14 x 7/2
= 21.98 meters.
A circle with a circumference of 24 meters
Circumference = 24 meters
A circle with a circumference of 5 pi
Circumference = 5π
= 5 x 3.14
= 15.7 meters
Thus,
The greatest circumference is 25.12 meters.

A number divided by eight minus thirteen is greater than negative six.
Answer:
(x/8) - 13 > -6
Step-by-step explanation:
If you want to take it further, add 13 to both sides to make it x/8 > 7. Then divide both sides by 8 to get x by itself. you are left with x > 7/8

He noticed that the fraudulent transaction had been made just a couple of days ago. He was aware that the card had been missing for a several months, but he had forgotten to inform the credit card company about the lost card. What’s the maximum amount sam will have to pay for this fraudulent transaction?
Answer:
The entire amount
Step-by-step explanation:
Sam will have to incur the amount of the transaction performed, this is because the transaction occurred using his credit card and he also attested to the fact that the card was missing for several month. After losing his credit card, Sam should have informed the credit card company about the development so that necessary steps could be taken, which he failed to do. For these, reason, Sam will have to bear the loss and pay the credit card company the entire sum.

A Ferris wheel has a 44-foot radius and the center of the Ferris wheel is 50 feet above the ground. The Ferris wheel rotates in the CCW direction at a constant angular speed of 3 radians per minute. Josh boards the Ferris wheel at the 3-o'clock position and rides the Ferris wheel for many rotations. Let tt represent the number of minutes since the ride started.
Write an expression (in terms of t) to represent the number of radians Josh has swept out from the 3-o'clock position since the ride started.
How long does it take for Josh to complete one full revolution (rotation)?
________ minutes
Write an expression (in terms of t) to represent Josh's height above the center of the Ferris wheel (in feet).
Write a function f that determine's Josh's height above the ground (in feet) in terms of t.
f(t)=
Answer:
Part A
The expression in terms of 't' representing the number of radians Josh has swept since the ride started is 3·t rad
Part B
The time to complete one revolution is (2·π/3) minutes
Part C.
The function 'f' that determines Josh's height above the ground (in feet) in terms of 't' is, f(t) = 44·sin(3·t + π/2) + 50
Step-by-step explanation:
The radius of the Ferris wheel = 44 foot
The height of the Ferris wheel above the ground = 50 feet
The direction of rotation of the Ferris wheel = CCW
The angular speed of the Ferris wheel, ω = 3 radians per minute
The position from which Josh boards the Ferris wheel = 3-O'Clock
The number of minutes since the ride started started = t
Part A
The expression in terms of 't' to represent the number of radians Josh has swept since the ride started = ω × t = 3 × t rad = 3·t rad
Part B
One complete revolution = 2·π radians
The time to complete one revolution = 2·π/ω = 2·π/(3 rad/minute) = (2·π/3) minutes = [tex]0.\overline{6}[/tex]·π minutes ≈ 2.0943951 minutes
Part C.
The height, 'h', of the Ferris wheel is given by the following sinusoidal relation
f(t) = A·sin(B·t + C) + D
Where;
A = The amplitude = The radius of the Ferris wheel = 44 ft.
The period, T = (2·π/3) minute
B = 2·π/T = 3
t = The time in minutes
D = The Ferris wheel's height above ground = 50 ft.
C = The horizontal shift = π/2 (Josh boards the Ferris wheel at t = 3-O'Clock which is the midline, a rotation of π/2 from the lowermost end of the Ferris wheel)
Therefore the function that determines Josh's height above the ground (in feet) in terms of 't' is presented as follows;
f(t) = 44·sin(3·t + π/2) + 50

Michelle deposited $1,600 into an account that is compounded continuously with an annual interest rate of 8%. After t years, there was $3,200 in the account. Based on the given information, if the formula for continuously compounded interest is A = P e r t , where P represents the initial amount of money, r represents the annual interest rate (as a decimal), t represents the number of years, and A represents the amount of money after t years, how many years had the money been in the account? Express your answer as a logarithm.
Answer:
As a logarithm, the money had been in the account for [tex]t = \frac{\ln{2}}{0.08}[/tex] years.
Step-by-step explanation:
The amount of money in the account after t years is given by:
[tex]A(t) = Pe^{rt}[/tex]
In which P is the initial amount deposited and r is the interest rate, as a decimal.
Michelle deposited $1,600 into an account that is compounded continuously with an annual interest rate of 8%.
This means that [tex]P = 1600, r = 0.08[/tex]
After t years, there was $3,200 in the account. How many years had the money been in the account?
This is t for which [tex]P(t) = 3200[/tex]. So
[tex]A(t) = Pe^{rt}[/tex]
[tex]3200 = 1600e^{0.08t}[/tex]
[tex]e^{0.08t} = \frac{3200}{1600}[/tex]
[tex]e^{0.08t} = 2[/tex]
[tex]\ln{e^{0.08t}} = \ln{2}[/tex]
[tex]0.08t = \ln{2}[/tex]
[tex]t = \frac{\ln{2}}{0.08}[/tex]
[tex]t = 8.67[/tex]
As a logarithm, the money had been in the account for [tex]t = \frac{\ln{2}}{0.08}[/tex] years.
The value of time t is [tex]\frac{ln(2)}{0.08}[/tex].
Given: P=1600
r=8%=0.08
t = ?
A=3200
Using the given compound interest formula we get:
[tex]A=Pe^{rt}\\3200=1600e^{0.08t}\\2=e^{0.08t}\\[/tex]
Take ln on both sides,
[tex]ln(2)=ln(e^{0.08t})\\ln(2)=0.08t\\t=\frac{ln(2)}{0.08}[/tex]
