7 0

Answer:

Let 7x be the rent paid for backhoe for seven hours.

Step-by-step explanation:

Keyword: maximum amount, the most

Inequality symbol: ≤

(800 × 5) + 7x ≤ 9,000

4,000 + 7x ≤ 9,000

7x ≤ 9,000 - 4,000

7x ≤ 5,000

7x ÷ 7 ≤ 5,000 ÷ 7

x ≤ 714.29

To the nearest hundreds:

x ≤ 700

ANSWER: The maximum rental fee per hour of backhoe is Php 700.00 (rounded off to the nearest hundreds).

To check if he paid less than 9,000 for the total rent:

(800 × 5) + (700 × 7) < 9,000

4,000 + 4,900 < 9,000

8,900 < 9,000 (True)

Francisco and Ryan are stuck simplifying radical expressions. Francisco has simplified to the quantity of x to the one half powe

Wewaii [24]

X to the one half power, over x to the three eighteenth power is equal to x to the one half power, divided by x to the one sixth power, which equals x to the power of (one half minus one sixth), or x to the one third power.

The twenty seventh root of the quantity of x to the second times x to the third times x to the fourth equals the twenty seventh root of x to the ninth power which equals x to the one third power. 

I cannot say whether Francisco and Ryan started with equivalent expressions but on final simplification they ended up the same. One might reasonably assume they started with equivalent expressions, but who knows if they made any mistakes in their simplifications.

Find the 50th term of the sequence 5, -2, -9, -16, ...

Elodia [21]

Answer:

-338

Step-by-step explanation:

So we have the sequence:

5, -2, -9, -16...

First, note that this is an arithmetic sequence.

This is because each individual term is the previous term added by a common difference.

We can see that this common difference is -7, because each subsequent term is 7 less than the previous one. For example, 5 minus 7 is -2, -2 minus 7 is -9, and so on.

So, to find the 50th term, we can write an explicit formula for our sequence.

The standard form for the explicit formula for an arithmetic sequence is:

$x_n=a+d(n-1)$
