Treat "13 4/5 feet below sea level" as a negative quantity.  Then add the increase, "1542 feet," obtaining

(1542 - 13 4/5) feet = 1528 1/5 feet above sea level.

Answer:  Second option is correct.

Step-by-step explanation:

Since we have given that

Distance a hike starts below sea level is given by

-13\frac{4}{5}\\\\=\frac{-69}{5}

( we used "negative sign" as it is below the sea level)

Distance a hike starts higher is given by

1542\ ft

According to question,

Total distance the hiker was above sea level at the end of the hike is given by

1542-\frac{69}{5}\\\\=\frac{7710-69}{5}\\\\=\frac{7641}{5}\\\\=1528\frac{1}{5}\ ft

Hence, Second option is correct.

Which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − StartRoot x EndRoot 8x3+ StartFraction 5 Over x E
kati45 [8]

Answer:

6x^2 - 6x + 5

Step-by-step explanation:

Given

List of Options

Required

Which of the options has a degree of 2

The general format of a polynomial is

ax^n + bx^{n-1} + ..... + cx^{n-n}

<em>Where n represents the degree </em>

In this case;

n = 2

Substitute 2 for n in expression above;

ax^n + bx^{n-1} + ..... + cx^{n-n}

ax^2 + bx^{2-1} + ..... + cx^{2-2}

ax^2 + bx^{1} + ..... + cx^{0}

ax^2 + bx + c *1

ax^2 + bx + c

Comparing this format to the list of given options; the option with the same format is: 6x^2 - 6x + 5

Where a = 6; b = -6 and c = 5

<em>Hence, the polynomial with a degree of 2 is </em>6x^2 - 6x + 5

The sum of two intcgers is -6. If one of them is 2, then the other is
zepelin [54]

Answer:

D) -8

Step-by-step explanation:

If you add a positive and a negative, you end up subtracting. If your sum is lower than any of the numbers you are adding together, then there is a negative. In this case, your only negative number is -8, but if there were others, you could find this equation by doing negative six minus two (because the equation was originally addition, it would still be subtraction to check your work or find the answer in this case.)

Hopefully you find this useful :)

Pedro opened a grilled cheese food cart. He insures his food cart for $90,000.00 for fire. What's his premium if the rate per $1
Nonamiya [84]
1.) Divide the value of the grilled cheese food cart by $100
     $90,000 / $100 = $900
2.) Multiply the quotient by the rate per $100
     $900 * $.83 = $747
3.) Therefore, B. $747 is Pedro's premium for his grilled cheese food cart
