The enrollment at a university increased from 1,000 students to 6,000 students over a 6-year period. What was the percent increase in enrollment over that time period?

Answers

Answer: 500%

Step-by-step explanation:

The percent increase is calculated as:

= (New number of students - Old number of students) / Old number of students * 100%

= (6,000 - 1,000) / 1,000 * 100%

= 5 * 100%

= 500%

Erin buys a bag of peanuts that weighs 3/4 of a pound later that week they the bag is two-thirds full how much does a bag oftwo-thirds full how much does a bag of peanuts weigh now

Answers

The full bag of peanuts weighs 3/4 pound.
But then someone ate 1/3 of the peanuts, and the bag is now only 2/3 full.
This means that there is only two-thirds of the original 3/4 pound remaining now.
This can be simply solved by: 3/4 * 2/3 = 2/4 = 1/2 pound

I'm not sure how to solve the first one, but I'll try to simplify sqrt3-1/sqrt3+1. I simplified it and I got 2-sqrt3. Does that help?

For question 2, I got -0.251.

Answer:

1) [tex]\frac{\sqrt{3}-1 }{\sqrt{3}+1}=\frac{(\sqrt{3}-1)^{2} }{(\sqrt{3}+1)(\sqrt{3}-1) }=\frac{4-2\sqrt{3} }{3-1}=\frac{4-2\sqrt{3} }{2}=2-\sqrt{3}[/tex]

1. Distributive property 2(5k-6) = 10k -12
2. Add 10k-12-4= - 3K -39 which is 10k-16= - 3K -39
3. Add to both sides 10k -16 +16 = 10k, -3k-39 + 16 = -3k-24, 10k = -3k-24
4. Add to both sides with variable
10k + 3k = 13k, -3k-24+3k = -24

Step-by-step explanation:

Use Pythagorean theorem,

hypotenuse² = 8² + 6²

                     = 64 + 36

hypotenuse = √100 = √(10*10)

Answers

Given:

Figure of similar triangles.

To find:

The value of x and the measure of NR.

Solution:

In triangle RST and RMN,

[tex]\angle SRT\cong \angle MRN[/tex]              (Vertically opposite angles)

[tex]\angle RST\cong \angle RMN[/tex]              (Alternate interior angles)

[tex]\Delta RST\sim \Delta RMN[/tex]                 (By AA property of similarity)

We know that, corresponding sides of similar triangles are proportional.

[tex]\dfrac{RS}{RM}=\dfrac{RT}{RN}[/tex]

[tex]\dfrac{40}{8}=\dfrac{60}{2x-2}[/tex]

[tex]5=\dfrac{60}{2x-2}[/tex]

[tex]2x-2=\dfrac{60}{5}[/tex]

On further simplification, we get

[tex]2x=12+2[/tex]

[tex]x=\dfrac{14}{2}[/tex]

[tex]x=7[/tex]

The value of x is 7.

Now,

[tex]NR=2x-2[/tex]

[tex]NR=2(7)-2[/tex]

[tex]NR=14-2[/tex]

[tex]NR=12[/tex]

Therefore, the value of x is 7 and the measure of NR is 12 units.

The first three terms of a geometric sequence are as follows.
2, 10, 50
Find the next two terms of this sequence.

Answers

Answer:

250, 1250

Step-by-step explanation:

Since 10/2 = 50/ 10 = 5, the common ratio = 5    So the next term in the sequence is found by multiplying the last term by 5.  

Therefore, 50 x 5 = 250 and 250 x 5 = 1250. So, the next two terms in your sequence are 250 and 1250

Sixty percent, or 12, of the students in Alex's class are going to the movies. 2/3, or 14, of the students in Mary's class are going to the movies. Which class has more students? Justify your answer using equations.

Answers

Answer:

Mary's class.

Step-by-step explanation:

One way to do this is to figure out how many students are in Alex's class and how many students are in Mary's class.

60% of Alex's class is 12 students

[tex]\frac{12*100}{60}[/tex]  = [tex]\frac{1200}{60}[/tex]= 20 students

[tex]\frac{2}{3}[/tex] or 66.66% (repeating) of Mary's class is 14 students

[tex]\frac{14*100}{66.66}[/tex] = [tex]\frac{1400}{66.66}[/tex] = 21 students

(^^66.66 repeating)

Mary's class has more students than Alex's class.

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.

Answers

Answer: Comedy

Step-by-step explanation:

Find out the percentages of each of the movies. First find the total quantity.

= 888 + 666 + 555 + 111

= 2,220 movies

Comedy = 888/2,220 * 100% = 40%

Action = 666 / 2,220 * 100% = 30%

Fantasy = 555/2,220 * 100% = 25%

Drama = 111/ 2,220 * 100% = 5%

222 movies out of 555 is:

= 222 / 555 * 100%

= 40%

222 movies out of 555 movies will therefore be comedy.

Answer:

222/555 are comedy
