The total number of points would be equal to 5n.

You would simply multiply 5 by the amount of questions. In this case, we do not know the amount, so we can use the variable n.

In 2004, Kenenisa Bekele of Ethiopia ran 5,000 meters (5 kilometers) in 12 minutes, 37.35 seconds. What is this distance to the

malfutka [58]

Answer:

Distance=3.1 miles

Step-by-step explanation:

Step 1: Determine how many meters make a mile

The conversion rate expression is;

1 mile=1.60934 kilometers

Step 2: Convert 5 km to miles

Using the expression below;

Distance in miles=distance in kilometers/1.60934

where;

distance in kilometers=5 km

replacing;

Distance in miles=5/1.60934

Distance in miles=3.10686 miles

Step 3: Round off to nearest tenth of a mile

Nearest tenth of a mile=1/10=0.1 , the same as rounding of to the nearest 1 decimal place

Distance 3.10686 miles rounded off to 1 decimal place=3.1 miles

Distance=3.1 miles

Which is a factor of 144 − 49x2? 12 - 7x2 72 – 7x2 12 – 7x 72 7x.

morpeh [17]

The factors of the given expression $144-49x^{2}$ will be $(7x+12)(7x-12)$

<h3>What will be the factors of the given equation?</h3>

It is given that

$144-49x^{2}$

Now by simplifying it

$(12)^{2} -(7x)^{2}$

Now from the formula, we know

$a^{2} -b^{2} = (a+b)(a-b)$

So it will become

$(12)^{2} -(7x)^{2}= (12-7x)(12+7x)$

Thus the factors of the given expression $144-49x^{2}$ will be (7x+12)(7x-12)

pt 1: possibilities for Joel winning a point- 1+1, 2+2, 3+3, 4+4, 5+5, 6+6, 1+3, 1+5 2+4, 2+6, 3+5, 4+6. Possibilities for Hiram winning a point- 1+2, 1+4, 1+6, 3+2, 3+4, 3+6, 5+2, 5+4, 5+6.

I am a little confused to why this would be something to ask about; it is straight forward. List the possible outcomes.
