Complete question :
Colleen and Caroline each built a rectangle out of square tiles placed in 3 rows of 5. Colleen used tiles that measured 1 2/3 cm in length. Caroline used tiles that measured 3 1/3 cm in length.
a. Draw the girls’ rectangles, and label the lengths and widths of each.
b. What are the areas of the rectangles in square centimeters?
c. Compare the areas of the rectangles.
Answer:
Colleen = 41.667 cm²
Carolina = 166.667 cm²
Carolina's rectangle is larger Than Collen's
Step-by-step explanation:
To start with, we determine the total number of tiles used
3 Rows of 5 ; 3 in 5 places = 15
Length of collen's square tiles : 1 2/3 = 5/3
Area of collen's square tiles = square of side length, = (5/3)² = 25/9
Area of rectangle formed = area of square * number of tiles
(25 /9) * 15 = 41.667 cm²
Length of carolina's square tiles : 3 1/3 = 10/3
Area of collen's square tiles = square of side length, = (10/3)² = 100/9
Area of rectangle formed = Area of square * number of tiles
(100/9) * 15 = 166.667 cm²
Carolina's rectangle is larger Than Collen's
Solve the equation

by factoring
Answer:
x= -1,-7
Step by step:
Answer:
x = -7 and -1
Step-by-step explanation:
Move the right side of the equation over to the left;
x^2+8x+7 = 0; Factor
(x+7)(x+1)=0 ; Solve for x;
x = -7 and -1

Answer:
[tex]7 \: books = 34.93 \: dollars \\ 1 \: book = ( \frac{1}{7} \times 34.93) \: dollars \\ = 4.99 \: dollars[/tex]
Jack can fill buckets of water four times fast as his sister Jill. They have to fill 400 buckets of
water for their village located at the bottom of a hill. Working together, Jack and Jill can complete
the job in six hours.
30. How many hours will it take Jack if he works alone?
Answer:
1.5 hour
Step-by-step explanation:
You divide 6 by 4.
Answer:
7.2 hrs
Step-by-step explanation:
Jack does 4/5 of the work in 6 hrs. He still needs to do 1/5 more if he's doing it by himself. 1/5 of 6 = 1.2 and 1.2 + 6 = 7.2 hrs
Five boys namely, Abel, Ben, Carlo, Dave and Elmer made a race. They all started at 7:10 in the morning. Abel finished the race at 7:18 a.M., Ben at 7:32 a.M., Carlo at 7:38 a.M., Dave at 7:42 a.M. And Elmer at 7: 52 a.M. About how many minutes did Abel finished the race?
Answer:
8 minutes
Step-by-step explanation:
minutes Abel completed the race = time finished - time started
7:18 - 7:10 = 8 minutes
Solve: 2x-4 = -(x-6)/2
Answer:
x = 14/5
Step-by-step explanation:
2x-4= -x-6/2
multiply by 2 on both sides to get rid of the fraction
4x-8= -x-6
add both sides by 8 and both sides by x to get the constants on the right and the variables on the left
4x+x=6+8
combine like terms/simplify
5x=14
divide both sides by 5 to isolate the x
x=14/5
i hope this helps :)
Consider the arithmetic sequence 10,12,14,16 if n is an integer, which of these functions generate the sequence?
Given:
The arithmetic sequence is:
10, 12, 14, 16, ...
To find:
The function that generates the given sequence if n is an integer.
Solution:
We have,
10, 12, 14, 16, ...
Here, the first term is 10 and the common difference is:
[tex]d=a_2-a_1[/tex]
[tex]d=12-10[/tex]
[tex]d=2[/tex]
The nth term of an arithmetic sequence is:
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term, d is the common difference and [tex]n\geq 1[/tex].
Putting [tex]a=10,d=2[/tex] in the above formula, we get
[tex]a_n=10+(n-1)2[/tex]
[tex]a_n=10+2n-2[/tex]
[tex]a_n=8+2n[/tex]
Therefore, the function [tex]a_n=8+2n, n\geq 1[/tex] generates the sequence.

Step-by-step explanation:
I know the answer can someone just help me explain it???
Step-by-step explanation:
It is Graph B. We can do this by checking the points. The equation given is d = 5t^2, where d technically is the y-coordinate and t is the x-coordinate. On Graph B, two obvious points are (1, 5) and (2, 20). We can check these points to see if they fit the equation.
(1,5): d = 5t^2
5 = 5(1)^2
5 = 5*1
5 = 5, so this point is correct.
(2, 20): = d = 5t^2
20 = 5(2)^2
20 = 5*4
20 = 20, so this point is correct.
We know that Graph A is incorrect because it doesn't follow the equation. The line goes through (1, 5), which we already know is correct, (2, 10), (3, 15), and (4, 20). We already figured out that (2, 20) is correct so (2,10) can't be correct. (3, 15) and (4, 20) are also incorrect but in this case, we only need to find one incorrect coordinate to validate our answer. Thus, as Graph A is wrong, Graph B is right.

Use a permutation expression to solve.
In a race of 43 people, how many different ways can the runners place in 1st, 2nd, and 3rd?
Answer:
74046
Step-by-step explanation:
Permutations = [tex]_np_r=\frac{n!}{(n-r)!}[/tex]
where r = choice of things from a set ( in this case the 3 places ) so r = 3
and n = amount of things ( in this case the 43 people ) so n = 43
We then plug in the values of n and r in the permutations formula
[tex]\frac{43!}{(43-3)!} =74046[/tex]
Hence the answer is 74046

find cot0 given cos0=2/7 and the terminal side is in quadrant IV
Answer:
0.2985
Step-by-step explanation:
find cot0 given cos0=2/7 and the terminal side is in quadrant IV
Given
cos theta = 2/7
theta = arccos(2/7)
theta = 73.40 degrees
cot theta = cot73.40
cot73.40 = 1/tan73.40
cot73.40 = 1/3.35
cot73.40 = 0.2985
hence the required answer is 0.2985
