Answer:

8.9 meters

Step-by-step explanation:

this seems like a problem where you can use the pythagorean theorem:

you know one of the two legs (6m) and  the hypotenuse (9m), you must find the other leg

a^2 + 6^2 = 9^2

a^2 + 36 = 81

a^2 = 45

a = \sqrt{45} or \sqrt{9} · \sqrt{5} which simplifies to be 3\sqrt{5} or approx. 8.9 meters

A truck that can carry no more than 6600 lbs is being used to transport refrigerators and upright pianos. each refrigerator weig
ZanzabumX [31]

Answer:

(a). 300r + 425p ≤ 6,600

(b). No, it’s not considered overweight

Step-by-step explanation:

In this question, we are to write an equation that shows the number of refrigerators and pianos the truck could carry.

Let the number of refrigerators be r and the number of pianos be p

By using their individual weights, the equation is as follows;

300r + 425p ≤ 6,600

To the second question, we want to consider if 10 refrigerators and 8 pianos are overload.

To get this, we simply multiply the number of each by their individual weights;

That would be;

300(10) + 425(8) = 3000 + 3,400 = 6,400 lbs

This is not considered overweight as it is less than 6,600 lbs

Can any one help me and work 2 or 3 of the problems for me to understand it
Alekssandra [29.7K]
To solve these problems you need to use the quadratic formula which is listed below. 

\frac{-b +/-  \sqrt{b^{2} - 4ac } }{2a}

So, if you take #2. 

The x^{2} has a 1 in front of it. The x has a -3 in front of it. The last number is also -3. So:

a = 1
b = -3
c = -3

Then you can plug all of these into the equation and simplify. Which gives you:

\frac{3 -/+  \sqrt{21} }{2}
