I believe it is the ratio 3 : 1.

<u>18 students chose the turkey sandwich</u>.

Since the class has a total of 24 students, we can deduce that <u>6 students chose the vegetarian sandwich</u>.

This gives us a ratio of 18 : 6.

When simplified, we get a ratio of 3 : 1.

Jenny has saved $3,800 over the last 12 months. She saved either $250 or $350 a month. During the 12 month period, how many time
Nana76 [90]

Answer:

Jenny save 4 times \$ 250 for the month

Step-by-step explanation:

Given Jenny has saved \$3,800 over the last 12 months.

She saved either \$250 or \$350 a month.

Let the number of months to save \$250 be x

Let the number of months to save \$350 be y

Total period is 12 month.

x+y=12 \ \ \ \ equation\ 1

Jenny has saved $3,800 over the last 12 months.

250x+350y=3800

Dividing both side from 50 we get,

\frac{250}{50}x+\frac{350}{50}y= \frac{3800}{50}

5x+7y=76 \ \ \ \ equation\ 2

Now Multiplying  equation 1 by 5 we get,

5\times(x+y)=5\times 12\\5x+5y=60\ \ \ \ equation \ 3

Now Subtracting Equation 3 by equation 2 we get,

(5x+7y=76)-(5x+5y=60)\\2y=16\\y=\frac{16}{2}= 8

Substituting the value of y in equation 1 we get,

x+y=12\\x+8=12\\x=12-8\\x=4

∴ Jenny save 4 Months of  \$ 250 and 8 Months of  \$ 350in a 12 month duration

How do you do number 1?
Alla [95]

Answer:

The decimal is not a rational number.

REASON:

A decimal can be a rational number if it fulfills any of the two conditions.

  • Condition 1:

            It must be Terminating. This means that the decimal should have finite number of digits.

  • Condition 2:

        If it is non-terminating decimal it should be Recurring. This means the decimal should repeat itself after some specific digits.

Pls Help! 100 Points!!!<br> Show all work to factor x^4 − 5x^2 + 4 completely.
Amiraneli [1.4K]

Answer:

(x+2)(x-2)(x+1)(x-1)

Step-by-step explanation:

We want to factor the expression x^4-5x^2+4.

First, notice that this is in quadratic form. In other words, both the exponents have even power.

Therefore, we can make a substitution to simplify the expression.

So, let’s let u=x^2.

Our expression is the same as:

(x^2)^2-5(x^2)+4

Substitute:

u^2-5u+4

Now, we can factor like normal. We can use -1 and -4. Therefore:

=(u-4)(u-1)

We can now substitute back u:

=(x^2-4)(x^2-1)

Both of these can be factored furthered using the difference of two squares:

(a^2-b^2)=(a+b)(a-b)

Therefore, we will have:

=(x+2)(x-2)(x+1)(x-1)

And we are done!
