Part a

we have the number

2.21\cdot10^{-6}=\frac{2.21}{10^6}=\frac{2.21}{1,000,000}=0.00000221

answer part a is

<h2>0.00000221 moles per liter</h2>

Part b

we have the number

260,000=2.6\cdot(100,000)=2.6\cdot10^5

answer Part b is

<h2> 2.6 x 10^5 pounds</h2>

Bob's truck averages 23 miles per gallon. If Bob is driving to his mother's house, 72 miles away, how many gallons of gas are ne
anyanavicka [17]

Answer:

3.1 gallons

Step-by-step explanation:

To solve this, we need to figure out how many gallons of gas go into 72 miles. We know 23 miles is equal to one gallon of gas, and given that the ratio of miles to gas stays the same, we can say that

miles of gas / gallons = miles of gas / gallons

23 miles / 1 gallon = 72 miles / gallons needed to go to Bob's mother's house

If we write the gallons needed to go to Bob's mother's house as g, we can say

23 miles / 1 gallon = 72 miles/g

multiply both sides by 1 gallon to remove a denominator

23 miles = 72 miles * 1 gallon /g

multiply both sides by g to remove the other denominator

23 miles * g = 72 miles * 1 gallon

divide both sides by 23 miles to isolate the g

g = 72 miles * 1 gallon/23 miles

= 72 / 23 gallons

≈ 3.1 gallons

the perimeter of a triangle is 49cm.One side is 7cm longer than another side and 5cm shorter than the third side find sides
pogonyaev

<em>P = a + b + c = 49 cm</em>

<em>a = b + 7 => b = a - 7</em>

<em>a = c - 5 => c = a + 5</em>

<em>_____________________</em>

<em>a + (a - 7) + (a + 5) = 49</em>

<em>3a = 49 + 7 - 5</em>

<em>3a = 51 </em>

<em>a = 17 cm</em>

<em>b = 17 - 7 = 10 cm</em>

<em>c = 17 + 5 = 22 cm</em>
