Answer:
Step-by-step explanation:
(a+b)² = a² + 2ab + b²
The only choice that has the form a² + 2ab + b² is D.
The square of a binomial is (p – r)². Then the correct option is D.
What is square binomial?The square binomial is a polynomial of two-term only and with power of 2. For example, (x + 5)² where x and 5 are the two separate terms.
Let's check the option D, we have
⇒ p² – 2pr + r²
We know that the formula a² – 2ab + b² = (a – b)², then we have
⇒ p² – 2pr + r²
⇒ (p – r)²
Then the correct option is D.

25% of Mr. Foster's class chose an amber background for their school picture. If 6 students chose an amber background, how many students are in Mr. Foster's class?
Answer:
24 studentsStep-by-step explanation:
25% of a hundred is one-fourth and because there are six students in a fourth of the whole we are multiplying four and six. 6x 4 is 24.
The percentage is calculated by dividing the required value by the total
value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
25% = 6 students
100% = 24 students
The total number of students in Mr. Foster's class is 24.
What is a percentage?The percentage is calculated by dividing the required value by the total
value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of students who chose an amber background = 6
25% of Mr. Foster's class chose an amber background for their school picture.
This means,
25% = 6
The total number of students = 100%
Now,
25% = 6 students
Multiply 4 on both sides.
4 x 25% = 4 x 6 students
100% = 24 students
Thus,
The total number of students in Mr. Foster's class is 24.

Given tan0 = 7/24 use the Pythagorean theorem to find the value of sin 0
Answer:
Step-by-step explanation:
Don't use 0 (or any other number) to replace θ. Use a letter variable such as x.
tan(x) = 7/24
sin(x)/cos(x) = 7/24
sin(x) = 7/√(7²+24²) = 7/√625 = 7/25

Answer:
the future value is $5,750.01
Step-by-step explanation:
The computation of the future value is shown below;
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $5,000 × (1 + 0.035 ÷ 12)^4 × 12
= $5,000 × (1 + 0.2916%)^48
= $5,750.01
Hence, the future value is $5,750.01

(in order) 196, 198, 248, 276, 289, 319, 349, 379 there are eight numbers.
--------------------------------------------------------------------------------------
196, 198, 248, 276
since the median is between 198 and 248, we must add both numbers together and divide them by two:
(198 + 248) ÷ 2
= 446/2
= 223 (first quartile)--------------------------------------------------------------------------------------
289, 319, 349, 379
since the median is between 319 and 349, we must add both numbers together and divide them by two:
(319 + 349) ÷ 2
= 668/2
= 334 (third quartile)--------------------------------------------------------------------------------------

Charlotte walks home from school every day at a rate of
4 miles per hour. It takes her 30-minutes to reach
home. Her brother, Noah, runs home from the same
school every day at a rate of 6 miles per hour. How
many fewer minutes does it take Noah than Charlotte
to reach home from school each day? Be sure to
SHOW your WORK!
Answer:
Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.
Step-by-step explanation:
Since Charlotte walks home from school every day at a rate of 4 miles per hour and it takes her 30-minutes to reach home, while her brother, Noah, runs home from the same school every day at a rate of 6 miles per hour, to determine how many fewer minutes does it take Noah than Charlotte to reach home from school each day the following calculation must be performed:
Charlotte:
4 mph = 4/60 = 0.0666 miles per minute
0.0666 x 30 = 2 miles
So the distance from the school to her house is 2 miles
Noah:
6/60 = 0.1 mile per minute
2 / 0.1 = 20
Thus, Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.
