Elaina wrote two correct variable expressions to represent the phrase “one-fourth of a number.” Which variable expressions could Elaina have written? Select each correct answer. A.) 4 ÷ n
B.) 4/n
C.) 1/4n
D.) n4

Answers

Answer 1
Answer:

Answer:

(1)/(4)n

(n)/(4)

C and D are correct options.

Step-by-step explanation:

The given phrase is “one-fourth of a number.”

Let the number be n.

one fourth means 1/4

Hence, the phrase “one-fourth of a number.” can be written as

(1)/(4)n

We can rewrite this expression by multiplying numerator as

(n)/(4)

Therefore, the required expressions are

(1)/(4)n

(n)/(4)

C and D are correct options.
Answer 2
Answer: 1/4n, and also D IF it's n/4.

Answers

Answer:

B

Step-by-step explanation:

Start by using the distance formula to find the raidus

The two points are (-2,1) and (-4,1)

√((-4+2)²+(1-1)²)= 2

The radius is two and we have our center which means we can write

(x+2)²+(y-1)²=4

now it's just a matter of expanding everyhting

x²+4x+4+y²-2y-3=0

x²+y²+4x-2y+1=0

This is equal to B

How do i round 186.282?

Answers


Well, first you need to decide what place you want to round it TO.

Example:  Round it to the nearest hundredth:

The next larger hundredth is  186.29 .
The next smaller hundredth is  186.28 .
Now look at it.
186.282  is closer to  186.28  than it is to  186.29 .
So the nearest hundredth is  186.28 .

-- When  186.282  is rounded to the nearest hundredth, it becomes  186.28 .

Similarly . . .
-- When  186.282  is rounded to the nearest tenth, it becomes  186.3 .
-- When  186.282  is rounded to the nearest whole number, it becomes  186 .
-- When  186.282  is rounded to the nearest ten, it becomes  190 .
-- When  186.282  is rounded to the nearest hundred, it becomes  200 .
-- When  186.282  is rounded to the nearest thousand or anything larger,
                                                                                       it becomes  zero.

I'm curious . . . where did this number come from ?

It happens to be one thousandth of the speed of light, in miles per hour.

Did it come up in science class, or did a science geek use it for
one of the problems in math ?
Okay so if you want to know how to Round all you have to remember is 4 or more add 1 more 4 or less just ignore.

If your rounding 186.282 in the tenths you would look in your tenths place and look at the number in the left. ( the number in the tenths place is 8)

So is 2 greater or lesser than 4?

its lesser.


so ignore the rest of the two numbers there ( 8 & 2)

And your answer would be 186.2

Two cyclists, 90 mi apart, start riding towards each other at the same time. One cycles twice as fast as the other. If they meet 3 hr later, at what average speed is each cyclist traveling?

Answers

The slower cyclist's speed is 10 mph, and the faster cyclist's speed is 20 mph.

Let's denote the speed of the slower cyclist as "x" miles per hour (mph). Since the faster cyclist is going twice as fast, their speed would be "2x" mph.

When they start riding towards each other, their combined speed is the sum of their individual speeds:

Combinedspeed = x + 2x

= 3x mph.

We are given that they meet 3 hours later and travel a totaldistance of 90 miles.

The distance each cyclist travels can be calculated using the formula:

Distance = Speed × Time.

For the slower cyclist:

Distance = x × 3

Distance = 3x miles.

For the fastercyclist:

Distance = 2x × 3

Distance= 6x miles.

Since they are 90 miles apart and have traveled a total distance of 90 miles when they meet, we can set up an equation:

Distance of slower cyclist + Distance of faster cyclist = Total distance

3x + 6x = 90.

Simplify the equation:

9x = 90.

Divide both sides by 9:

x = 10.

So, the speed of the slower cyclist is 10 mph, and the speed of the faster cyclist is 2x which is 20 mph.

Factor completely 3x2 + 5x + 1.(3x + 1)(x + 1)

(3x + 5)(x + 1)

(3x − 5)(x + 1)

Prime

Answers

Answer:

(D)

Step-by-step explanation:

The quadratic equation is in the form :

(x+p)(x+q)

x^2+px+qx+pq

x^2+(p+q)x+pq

and In the above, (p + q) = b and pq = c.

To factor a quadratic, we'll need to start by finding the two numbers (being the p and the q above) that add up to equal b, where those numbers also multiply to equal c.

Since, both 3 and 5 in the given equation 3x^2+5x+1 are prime numbers, thus the given equation cannot be factorised because of the prime nature.

Hence, option D is correct.
Factor completely: 3x2 + 5x + 1
multiples of 1:
1*1=1   1+1=2

3x2 + 5x + 1 can not be factored anymore, it's prime
