Rosa is making a game board that is
16 inches by 24 inches. She wants to
use square tiles. What is the largest
tile she can use?
Please show working
Answers
Answer:
8" by 8"
Six of those will fit on the board
Step-by-step explanation:
Answer:
The largest tile she can use is a 8 inches by 8 inches tile.
Step-by-step explanation:
Rosa is making a game board that is 16 inches by 24 inches.
She wants to use square tiles.
The area of the game board (area of a rectangle) is equal to length times width.
∴ Area = 16 inches × 24 inches = 384 square inches
The prime factors of 384 are; 2^7 × 3
We can put it as;
2^6 × 6 = 384
The square root of 2^6 is 2^3 = 8
So Rosa will need six square tiles of 8 inches by 8 inches each.
Hence the largest tile she can use is a 8 inches by 8 inches tile.

12. Find m please help.
Answers
Answer:
m<ADE = 59°
Step-by-step explanation:
Each angle of a rectangle = 90°
Therefore:
m<ABE + m<CBE = 90°
(4x + 15)° + (13x + 7)° = 90°
Solve for x
4x + 15 + 13x + 7 = 90
17x + 22 = 90
17x = 90 - 22
17x = 68
x = 68/17
x = 4
✔️Opposite sides (AB and DC) of the rectangle are parallel, therefore:
m<ADE = m<CBE
m<ADE = (13x + 7)° (Substitution)
Plug in the value of x
m<ADE = 13(4) + 7
m<ADE = 52 + 7
m<ADE = 59°
Sam has worn a green shirt on 10 of the last 20 days. Considering this data, how many times
would you expect Sam to wear a green shirt in the next 12 days?
Answer quickly
Answers
I think it is 6 because 10 is half of 20 so 6 is half of 12
Sam should wear green shirt for 6 days in next 12 days.
What is fraction?Fraction is a number that represent part of a whole quantity. It has two parts, numerator and denominator, the number above the horizontal line is numerator, and number under the the line is denominator.
Given,
Sam wore green shirt on 10 of the last 20 days
Fraction of days the wearing green shirt to total days = 10/20 = 1/2
Number of days of wearing green shirt in next 12 days
= 12 × 1/2
= 6 days
Hence, in next 12 days, Sam should wear green shirt for 6 days.

Which function produces an output of 5 for an input of -6?
A.f(x) = x + 1
B.f(x) = 2x + 4
C.f(x) = x - (-1)
D.f(x) = -x - 1
Answers
Answer:
The answer is D
Step-by-step explanation:
Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)

The function f(x)=(25)x
is shown on the coordinate plane. Which statement is true?
Answers
Answer: In the right end, as x increases without bound, the graph of f(x) decreases.
In the left end, as x decreases without bound, the graph of f(x) increases.
Step-by-step explanation:
According to the graph, the end behaviour of the function in the image is decreasing without bound. When we graph a function, with put an arrow to indicate when a function increases or decreases without bound, that's why in this case we can say the decreases without bound, the function extends without limit.
Therefore, as the x increases, f(x) decreases. If you carefully pay attention to the graph, x is constantly increasing in the right end, and f(x) is more and more close to the x-axis.
