The Lake Smith basketball team had a team picture taken of the players, the coaches, and the trophies from the season. The picture was 4 inches by 6 inches. The team decided to have the picture enlarged to a poster and then enlarged again to a banner measuring 48 inches by 72 inches.
If the scale factor from the picture to the poster is 500%, find the dimensions of the poster.
What scale factor, as a percent, is used to create the banner from the picture?
What percent of the area of the picture is the area of the poster?
Assume you started with the banner and wanted to reduce it to the size of the poster.
What would the scale factor as a percent be?
9514 1404 393
Answer:
poster dimensions: 20 inches by 30 inchesbanner/picture scale factor: 1200%poster/picture area ratio: 2500%poster/banner reduction ratio: 41.67%Step-by-step explanation:
a) Poster dimensions are 500% of the picture dimensions:
500% · 4 in = 500/100 · 4 in = 5 · 4 in = 20 in
5 · 6 in = 30 in
The poster is 40 in by 30 in.
__
b) The ratio of banner sized to picture size can be found from the ratio of the smaller dimensions:
48 in/(4 in) = 12 = 12 · 100% = 1200%
__
c) The poster/picture area ratio is the square of the scale factor:
poster area/picture area = (500%)^2 = (500/100)^2 = 25
= 25 · 100% = 2500%
__
d) The poster/banner reduction ratio is ...
20 in/48 in = 5/12 ≈ 0.4167 = 0.4167 · 100% = 41.67%
_____
Additional comment
To convert a number or fraction to a percentage, multiply by 100%. To convert a percentage to a number, divide by 100%, or recognize that "%" means "/100". (As above, 500% = 500/100 = 5.)

Step-by-step explanation:
ur welcome plz mark brainliest
2/5 t is the probability that the balloon will be either red or blue.
Thus option A is correct.
What is probability?The mathematical discipline known as probability specializes in determining the possibility of an event occurring. Probability, which expresses the probability of a risk, is calculated by dividing the total possible combinations by the frequency of favorable events. Composite reliabilities vary from 0 to 1, with 1 representing certainty and 0 representing hesitation.
The probability of the event will be taken as
The fact that the data of red and blue will have a chance of occurring in the event
The first draw chance would be 20/100 = 1/5
The second draw would be 20/100 = 1/5
P = 20 / 100 + 20 / 100
P = 1/5 + 1/5
P = 2/5
Therefore, option D is the correct option.

Find common denominators. Note that what you do to the denominator, you do to the numerator.
Use 15 as the common denominator:
(-2/5)(3/3) = (-6/15)
(4/3)(5/5) = (20/15)
Combine like terms:
-6/15 + 20/15 = (20 - 6)/15 = 14/15

The map shows the location of the airport and a warehouse in a city. Though not displayed on the map, there is also a factory 104 miles due north of the warehouse.
Coordinate grid shown from negative 78 to positive 78 on x axis at intervals of 13 and negative 78 to positive 78 on y axis at intervals of 13. A straight line is shown between the points labeled Airport and Warehouse. Airport is the ordered pair negative 39, 52, and Warehouse is the ordered pair 39 and negative 52. A signage showing directions North, South, East, and West is shown in the empty quadrant on the graph.
A truck traveled from the warehouse to the airport and then to the factory. What is the total number of miles the truck traveled?
130
169
201
208
step 1
find the coordinates of the factory
the factory is 104 miles due north of the warehouse
the coordinates of the warehouse are (39,-52)
coordinates of the factory------> (39,-52+104)------> (39,52)
step 2
find the distance warehouse to airport
let
A coordinates of warehouse-------> A( 39,-52)
B coordinates of airport---------> B(-39,52)
C coordinates of factory-------> C(39,52)
distance AB=√[(52+52)²+(-39-39)²]------> distance AB=130 miles
step 3
find the distance airport to factory
B(-39,52)
C(39,52)
distance BC=√[(52-52)²+(39+39)²]-----> distance BC=39 miles
the total number of miles=distance AB+distance BC---> 130+39
the total number of miles=169 miles
Thus the answer is 169

Lazarus’ Boat Rentals charges a yearly fee of $105 and $9.50 each time a member wants to rent a boat. Robert’s Boat Rentals does not charge a yearly fee but charges $14.75 every time a member rents a boat. How many times would a person have to rent a boat for Lazarus’ and Robert’s charges to be equal
Answer:
The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal = 20 times
Step-by-step explanation:
Answer: The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal is 20 times
Step-by-step explanation:
The given information are:
For the Lazarus' Boat Rentals company
The yearly charges by Lazarus' boat company = $105
The charge each time a member rents a boat = $9.50
For the Robert's Boat Rentals company
The yearly charges by Robert's boat company = $0
The charge each time a member rents a boat = $14.75
Let the number of times required before the charges for both Lazarus' Boat Rentals company and Robert's Boat Rentals company to be equal, we have:
$105 + $9.50 × t = $14.75 × t
∴ t = $105/($14.75 - $9.50) = 20 times
The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal = 20 times.
