Which symbol can be used to correctly compare the two fractions?

1 answer:

3 0

The real question you need to solve is "Is 1/4 greater than, equal, or less than 15/100?" At first glance it's hard to determine how they relate to each other. So first make both fractions use the same denominator. The easiest way to do this is multiply both the numerator and denominator of each fraction by the denominator of the other fraction. So 1/4 * 100/100 = 100/400 and 15/100 * 4/4 = 60/400 Now ask yourself "Is 100/400 greater than, equal, or less than 60/400?" and the answer is pretty obvious. 100/400 > 60/400. So the answer is ">".

Here are the first four terms of a sequence.

Nataly_w [17]

Answer:

aₙ = 2n² + n + 1

Step-by-step explanation:

We observe that the difference of terms is 4, 7 and 15 and next level difference is 4. It means the sequence is quadratic.

We can compare this with simple quadratic sequence

1, 4, 9, 16

and find out that doubling each term gives us

2, 8, 18, 32

This is close to our sequence, write the terms as follows to find exact rule

The first term:

a₁ = 4 = 2*1² + 2 = 2*1² + 1 + 1

The second term

a₂ = 11 = 2*2² + 3 = 2*2² + 2 + 1

The third term:

a₃ = 22 = 2*3² + 4 = 2*3² + 3 + 1

The fourth term:

a₄ = 37 = 2*4² + 5 = 2*4² + 4 + 1

The nth term as per observation above is:

aₙ = 2n² + n + 1

-8xc = 1 solve for x

Nastasia [14]

Answer:

[-8c]⁻¹ = x

Step-by-step explanation:

-8xc = 1

____ ___

-8c -8c

$x = - \frac{1}{8c} \\ \\ or \\ \\ x = ({ -8c})^{-1}$

This, according to the Negative Exponential Rule [Reverse], is how you write this as a rational exponent. You bring the denominator to the numerator while ALTERING THE INTEGER SYMBOL FROM POSITIVE TO NEGATIVE:

b⁻ⁿ = 1\bⁿ

An object travels along a circular path so that it completes one revolution in 8 seconds. If the linear velocity of the object i

natima [27]

Answer:

Using the concept of speed-distance-time, we find that the diameter of the circular path is 12 inches.

Step-by-step explanation:

Given that the object completes one revolution in 8 seconds. So, the circular speed of the object is 2πr/8 = πr/4 inches per seconds, where r is the radius of the circular path. The speed can be written as:

πr/4 inches per seconds = 60πr/4 inches per minute = 15πr inches per minute.

But, it is given that the circular speed of the object is 90π inches per minute. So,

90π = 15πr

r = 6 inches

Since, diameter is the double of radius, d = 2r = 12 inches.
