Answers

Answer:

a = 4, b = 6 and c = 5

Step-by-step explanation:

It is given that,

[tex]\dfrac{\dfrac{1}{4}}{\dfrac{5}{6}}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]

We know that,

[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]

So,

[tex]\dfrac{1}{4}\times \dfrac{6}{5}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]

If we compare both sides of the equation we get,

a = 4, b = 6 and c = 5

Hence, these are the values of a,b and c.

Find the 7th term of the arithmetic sequence given a12=29 and
a16=53
a7=___

Answers

Answer:

Thus: a7=-1

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

We know: a12=29, a16=53, thus

[tex]a_1+(12-1)r=29[/tex]

[tex]a_1+(16-1)r=53[/tex]

Simplifying:

[tex]a_1+11r=29[/tex]

[tex]a_1+15r=53[/tex]

Subtracting both equations:

[tex]4r=53-29=24[/tex]

Solving:

[tex]r=24/4[/tex]

r=6

The 7th term can be found as 5 terms before the 12nd:

[tex]a_7=a_{12}-5r[/tex]

[tex]a_7=29-5*6=29-30=-1[/tex]

Thus: a7=-1

The 7th grade class experienced a 15% decrease in enrollment.Last year,the 7th grade class had 280 students. How many how many students are enrolled in the 7th grade this year?

Answers

Answer: 238

Step-by-step explanation: 10% of 280 is 28. 1% of 280 is 2.8. Multiply 2.8 times 5 and you get 14. Add 10% and 5% (28+14) and you get 15% which is 42. Subtract 42 from 280 and you get 238.

Answer:

232 students are enrolled this year.

Step-by-step explanation:

Since 15% of the enrollment of the previous year is gone, you must take 15% of the total number of students and subtract that from the total number of students.

[tex]280*0.15=42[/tex]

This tells us that the 15% decrease means there are 42 fewer students enrolled this year. Now you would just subtract 42 from 280.

280 - 42 = 232

2x+2a=4b solve for a

Answers

Answer:

a=2b-x

Step-by-step explanation:

Simplifying
2x + 2a = 4b

Reorder the terms:
2a + 2x = 4b

Solving
2a + 2x = 4b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2x' to each side of the equation.
2a + 2x + -2x = 4b + -2x

Combine like terms: 2x + -2x = 0
2a + 0 = 4b + -2x
2a = 4b + -2x

Divide each side by '2'.
a = 2b + -1x

Simplifying
a = 2b + -1x

PLEASE HELP ASAP!!If an element has the atomic number of 13 and a mass number of 27, whatis that element?-cobalt-aluminum-silicon To Dye or Not To Dye It is not uncommon for teenagers to want to experiment with their appearance. As teens try to figure out who they are, they may try different styles of clothing. Another common way for teens to experiment with their look is with hair color. However, many school systems and parents insist that teens simply are not old enough to make such changes. Is a little hair dye really that bad? Many schools now state in their policy that "unnatural hair colors," such as pink or blue, are not allowed. Schools say that such hair colors can be a distraction. For instance, students may focus on someone's blue hair during class. On the other hand, is it not just as likely that someone will be so focused on someone who dyed his or her hair from black to blonde? This logic seems faulty at best, and schools should probably put more time into what their students are actually learning. There are plenty of parents who do not want their teens dyeing their hair either. There are countless potential disagreements that may arise between parents and their teens. So, is something such as hair color really worth it? Parents should put time into making sure their children do well in school, eat right, and exercise. It certainly seems preferable to deal with a teen having blue hair for a month than to deal with a teen who is not allowed to be himself or herself. Leave the question of to dye or not to dye up to teens. There will be plenty of other opportunities for schools and parents to tell these kids no.
