B- $3.00
19/1.14 = .06
.06 x 50 = $3.00
Answer:
<em>A container can hold 473.176 ml</em>
<em>42.52 grams is nitrogen. </em>
Step-by-step explanation:
<u>Part A:</u>
We have given that a container holds 0.500 qt . Now we have to find how many milliliters of lemonade it can hold.
We know that 1 qt = 946.353 ml
To find how many milliliters of lemonade a container hold, we have to convert 0.500qt into ml.
As we have mentioned above that 1 qt = 946.353 ml
Multiply the volume value by 946.353
.
0.500 * 946.353
= 473.176 ml
<em>It means a container can hold 473.176 ml</em>
<u>Part B:</u>
Convert the unit oz to grams. The ratio is 1 ounce is to 28.34 grams.
We have 10.0 oz.
10* 28.34 = 283.495
This would mean 10 oz is equivalent to 283.50 grams. It is given that the fertilizer is 15% by mass nitrogen. It means for every 100 g of fertilizer 15 grams of that is nitrogen. Hence for every 283.50 grams of fertilizer
<em>283.50 * (15/100) = 42.52 grams is nitrogen. </em>

Answer: Non-proportional
Step-by-step explanation:
The unit rate for the gas per gallon is $3.17. You want to find out if that is equal to the amount you would pay for 10 gallons at once. If you multiply the unit rate by ten, you would get 10 gallons = $31.70
So...you know that it is not proportional
Answer:
216 inches
Step-by-step explanation:
A decagon has 10 sides (think decade and decathlon). From the center of the decagon we draw the radii and in doing so we take the area of the decagon and divide it into 10 congruent Triangles.
The angles around the center add up to 360 because they form a circle and since there are 10, they each measure 36 degrees. So the answer to the first part (the angle between the radii) is 36 degrees.
Each of these triangles has two equal sides (both radii) so is Isosceles. That means that the base angles are congruent. So the two angles that are left in each triangle must measure the same. Since the angles in a triangle add up to 180 degrees, we know that the two remaining angles are together equal to 180-36=144 degrees. Since they are equal in measure they each measure 72 degrees.
Thus the answer to the second part, trhe measure of the angle between a radius and the side of the polygon is 72 degrees.
