Find the equation for the area, A, of the rectangle with a length of n-5 and a width of n-1.
A A=n(n-1)+5(n-1)
B n^2-5n+5
C n^2-6n+5
D n^2+5

Answers

Answer 1

Answer:

C. [tex]n^{2}[/tex]-6n+5

Step-by-step explanation:

Area of a rectangle =l x w

A=(n-5)(n-1)

Use distributive property

[tex]n^{2}[/tex]-n-5n+5

Combine like terms

[tex]n^{2}[/tex]-6n+5

Answer 2
the answer to this would be C

2.1 Yards of Black Material.

Step-by-step explanation:

The problem is a simple multipication problem.

Take 1.75, and multiply that by 1.2. The answer comes out to 2.09. Since the 9 in the .09 part is above 5, you would round that up, which gets you the answer of 2.1 Yards.

This question is really hard

Answer:

1. [tex]\frac{1}{4}[/tex]

2.[tex]\frac{5}{6}[/tex]

3.[tex]\frac{3}{10}[/tex]

4. 1[tex]\frac{1}{8}[/tex]

5. 2[tex]\frac{6}{7}[/tex]

6. 3[tex]\frac{8}{9}[/tex]

Step by Step Explanation

I used the same method with all 6 questions, I had to tweak it slightly for the last 3 as they were mixed fractions.

For the first 3 questions, I used the number you had to make and multiplied it by the denominator. Let's use the first questions as an example.

We need to make 7 by adding something to 27/4. I multiplied 7 by 4 in order to get 28.

This means your goal is to get to 28/4.

The difference between 28/4 and 27/4 is 1/4. Meaning you only have to add 1/4 in order to make 7.

For the last 3 questions I first sorted the fractions out. Let's use the first question again on the right side as an example.

I made 5[tex]\frac{7}{8}[/tex] a top heavy fraction by first multiplying 5 by 8, which makes 40. I then added 40 to 7 making 47. Now the fraction is 47/8.

Now that we have our top-heavy fraction we do the same as last time. We need to make 7. So we multiply 7 by 8 and that makes 56. The difference between 56 and 47 is 9. So we need 9/8 in order to get to 56/8. We need a mixed fraction so 9/8 becomes 1[tex]\frac{1}{8}[/tex].

I hope this helps, if this was confusing don't be afraid to ask questions.

If line segment AB is 400%, what is the length of a line segment that is 100%?
_____ inch(es)
(Type a whole number or a decimal) ​

Answers

4 divided by 4, equals 1 so that means that 100% out of 400% of the line is equal to 1 inch

If line segment AB is 400%, 1 in is the length of a line segment that is 100%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

from the given diagram, we get,

the line AB = 4 in.

and,  line segment AB is 400%,

now, we have to find the length of a line segment that is 100%.

so, we get,

4 in = 400%

so, 100% = 4/ 400 * 100

               = 1 in.

Hence, If line segment AB is 400%, 1 in is the length of a line segment that is 100%.

Answer:

Onions- $1.20

Potatoes- $1.44

Step-by-step explanation:

.32p+.48n=

.32(4.5)+.48(2.5)=

1.44+1.2=264

1 pound of potatoes = $0.32
1 pound of onions = $0.48

(POTATOES)
4 pounds of potatoes = 0.32 x 4 (= 1.28)
0.5 pounds of potatoes = 0.32 / 2 (= 0.16)

1.28 + 0.16 = 1.44

4.5 Pound Of Potatoes = $1.44

(ONIONS)
2 pounds of onions = 0.48 x 2 (= 0.96)
0.5 pounds of onions = 0.48 / 2 (= 0.24)

0.96 + 0.24 = 1.2 = 1.20

CONCLUSION
4.5 pounds of potatoes is $1.44, and 2.5 pounds of onions is $1.20

I think it’s 16 and 8

Answer:

16/8

Step-by-step explanation:

All you have to do to calculate the size of the new shape is take both numbers and multiply them by 4

The width is 4 inches, so

4x4=16

The height is 2 inches, so

2x4=8

If you're wanting to calculate the area of the new shape, just multiply 16 by 8.

16x8=128

If you need to calculate the perimeter of the shape, do this

16+16+8+8=48.

Hope this helped!

(2) Provided that its a scene commonly played for laughs, in reality, sleep deprivation in teenagers is no laughing matter. (3) Adolescents have unique sleep patterns, and with an early school start, many are doggedly tired, leading to serious health and safety risks. (4) Thus, middle and high schools across the United States should heed the advice of doctors and start classes no earlier than 8:30 a.m.(5) Contrary to the notion that teenagers are naturally sluggish, they have a biological excuse for having trouble getting up at 5:00 or 6:00 a.m.: adolescents undergo a shift in their circadian rhythm, making it harder for them to fall asleep as early as adults or younger children. (6) The typical sleep cycle for teenagers begins at 11:00 p.m., when their bodies release melatonin, the sleep-inducing hormone. (7) In order for teenagers to get the full nine hours of sleep they need for optimal performance, they would have to sleep in until 8:00 a.m.(8) Now that experts better understand the sleep needs of adolescents, the average teenager gets fewer than seven hours of sleep a night. (9) Not only that, but waking before 8:00 a.m. interrupts their REM sleep, a critical stage of sleep that enables emotional regulation.(10) Indeed, continual sleep deprivation is bad. (11) Teenagers who get inadequate sleep are more likely to be overweight, have depression, perform poorly in school, and engage in risky behaviors.
