Answer:

9/10

Step-by-step explanation:

step 1

Compare the slopes

1/10=0.10

9/10=0.9

0.9 > 0.10

therefore

An experienced skier would like the 9/10 hill slope because it is steeper, while the 1/10 is a softer slope.

ANEK [815]
Just subtract 622 feet from 486 feet to get the change in elevation.  The result will be negative because your friend's house is at a lower elevation than yours.

Now find the mean change in elevation per mile by dividing (486 ft - 622 ft) by 4 miles:
                      -136 ft
                    -----------  = -34 ft/mile

Answer:

2x² + 9x - 5

Step-by-step explanation:

Given

(2x - 1)(x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x + 5) - 1(x + 5) ← distribute both parenthesis

= 2x² + 10x - x - 5 ← collect like terms

= 2x² + 9x - 5

At a ski resort, 1/4 of the 300 skiers are beginners, and 1/4 of the 260 snowboarders are beginners. The resort staff used the d
Evgen [1.6K]

\frac{1}{4}(300 + 260) = \frac{1}{4} \times 300 + \frac{1}{4} \times 260 is the expression that demonstrates the distributive property

<em><u>Solution:</u></em>

Given that,

At a ski resort, \frac{1}{4} of the 300 skiers are beginners

\frac{1}{4} of the 260 snowboarders are beginners

The resort staff used the distributive property to make the calculation of the total number of beginners on the ski slopes

Beginners in skiers = \frac{1}{4} of the 300

Beginners in snowboarders = \frac{1}{4} of the 260

Total number of beginners = Beginners in skiers + Beginners in snowboarders

\text{ Total number of beginners } = \frac{1}{4}(300) + \frac{1}{4}(260)

We have to use distributive property

The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum

<h3>a(b + c) = ab + bc</h3>

<em><u>Therefore, our expression is:</u></em>

\frac{1}{4}(300) + \frac{1}{4}(260)

We have to take \frac{1}{4} as common term to get distributive property

\frac{1}{4}(300) + \frac{1}{4}(260) = \frac{1}{4}(300 + 260)\\\\\frac{1}{4} \times 300 + \frac{1}{4} \times 260 = \frac{1}{4}(300 + 260)

Thus distributive property is applied
