The area of the rectangular base of his friend's tank is 468.75 square inches. So, Option D is correct.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
One of Julian's friends also has a rectangular aquarium.
The dimensions of his friend's tank are each exactly 1 1/4 times the dimensions of Julian's tank.
Let x be the length of Julian's tank.
Let y be the width of Julian's tank.
So, the Area of Julian's tank = length × Width
= xy
Since we are given
300 = xy
Now we are given that the dimensions of his friend's tank are each exactly times the dimensions of Julian's tank.
So, the length of his friend's tank = 5/4 x
So, the width of his friend's tank = 5/4 y
So, Area of his friend's tank = ( 5/4 x) (5/4 y)
= 25 / 16 xy
= 25 / 16 (300)
= 468.75
Hence the area of the rectangular base of his friend's tank is 468.75 square inches.
So, Option D is correct.

42. Which of the following expressions is equal to
(sin 60°)(cos 30º) + (cos 60°)(sin 30°) ?
F. cos(60° -30°)
G. cos(60° +30°)
H. sin(60° -30°)
J. sin(60° +30°)
K. sin(60* 430")
+ °
2
Answer:
sin ( 60° + 30° )
Step-by-step explanation:
There is a formula : -
sn ( A + B ) = sin A cos B + cos A sin B
Here,
A = 60°
B = 30°
So,
( sin 60° ) ( cos 30° ) + ( cos 60° ) ( sin 30° ) = sin ( 60° + 30° )
4 pencils and 3 crayons are 20.7 inches. 5 pencils and 4 crayons are 26.4 inches. Each pencil is the same length as the other pencils, and each crayon is the same length as the other crayons. What is the length of 1 pencil? What is the length of 1 crayon?
Call the pencils x, the crayons y.
4x + 3y = 20.7 inches -> 16x + 12y = 82.8 inches.
5x + 4y = 26.4 inches -> 15x + 12y = 79.2 inches.
We minus the top one from the bottom -> x = 82.8 - 79.2 = 3.6 inches
Replace back : 4 x 3.6 + 3y = 20.7
14.4 + 3y = 20.7
3y = 6.3
y = 2.1
So, the length of 1 pencil is 3.6 inches, the length of 1 crayon is 2.1 inches
Recheck : 4 pencils and 3 crayons = 3.6 x 4 + 2.1 x 3 = 14.4 + 6.3 = 20.7
5 pencils and 4 crayons = 3.6 x 5 + 2.1 x 4 = 18 + 8.4 = 26.4

To Find:
What kind of sequence is this?
Solve:
Let's make a table:
[1 stack] 45
[2 stack] 38
[3 stack] 31
[4 stack] 24
Now all we have to do is subtract to see what each is:
45 - 38 = 7
38 - 31 = 7
31 - 24 = 7
Thus,
[1 stack] 45 ⇒ 7
[2 stack] 38 ⇒ 7
[3 stack] 31 ⇒ 7
[4 stack] 24 ⇒ 7
Hence, each stack is going down by 7.

You, Bryce, and Karissa are trying to determine which paper towel brand will

Bryce wants to use the data to determine which team cleans the fastest. Use
the information from all three time intervals to determine rates for each
brand.
Which team (Brand A, Brand B, or Brand C) do the data suggest can clean the
spill the fastest?
Explain how you determined your answer, including specific rates for each
bran
The data of brand C suggests that brand C has the fastest clean time because it has the least average time
How to determine the brand that suggest the fastest?To do this, we simply calculate the average time of each brand.
From the complete question, we have:
Brand A: 20, 40, 60
Brand B: 30, 60, 90
Brand C: 15, 30, 45
The average is calculated using:
Average = Sum/Count
So, we have:
Brand A = (20 + 40 + 60)/3 = 40
Brand B = (30 + 60 + 90)/3 = 60
Brand C = (15 +30+ 45)/3 = 30
The least clean time is 30 (brand C).
Hence, the data of brand C suggests that brand C has the fastest clean time

The two-way table with 5 columns and 3 rows, where the first column is labeled Boys, girls, total, and the entries in the columns match the ones in the second option.
Option B is the correct answer.
What is the two-way table?A two-way table is a table used to display the frequency distribution of two categorical variables.
It is also called a contingency table because it helps to examine the relationship between two variables, to see if they are dependent or independent.
We have,
A 5-column table has 3 rows.
The first column has entries Boys, girls, total.
The second column is labeled A with entries 12, 16, 28.
The third column is labeled B with entries 24, 30, 54.
The fourth column is labeled C with entries 12, 12, 24.
The fifth column is labeled Total with entries 48, 58, 106, represents the given information.
To understand why this is the correct two-way table, let's go through each row and column of the table:
The first row of the table shows the number of boys and girls who took the test, as well as the total number of students.
We are told that there are 106 total sophomores, so the entry in the "total" column is 106.
We are also told that there are 48 boys who received an A, B, or C on the test, so the entry in the "total" column for boys is 48.
Subtracting this from the total number of students gives us the number of girls:
106 - 48 = 58.
The second row of the table shows the number of students who received an A on the test.
We are told that there are 28 total A's, and out of those, 16 were received by girls.
This means that 28 - 16 = 12 A's were received by boys.
Therefore, the entries in the "A" column are 12 for boys and 16 for girls, which matches the table.
The third row of the table shows the number of students who received a B on the test.
We are told that there are 54 total B's, and out of those, 30 were received by girls.
This means that 54 - 30 = 24 B's were received by boys.
Therefore, the entries in the "B" column are 24 for boys and 30 for girls, which matches the table.
The fourth row of the table shows the number of students who received a C on the test.
We are told that there are 24 total C's, and out of those, 12 were received by boys.
This means that 24 - 12 = 12 C's were received by girls.
Therefore, the entries in the "C" column are 12 for boys and 12 for girls, which matches the table.
Thus,
The two-way table with 5 columns and 3 rows, where the first column is labeled Boys, girls, total, and the entries in the columns match the ones in the second option.
