Answer:
B
Step-by-step explanation:
I got 100 on my test and that was my answer
If a something with the value of $179,000 dollars decreased in value annually by 3% you would show this by setting a graph or depiction of the drop. You could do this with a line graph to show the slow decrease in value or a bar graph to show how the value is getting smaller
Below are the choices:
A. 80 mL of the 3.5% solution and 120 mL of the 6% solution
<span>B. 120 mL of the 3.5% solution and 80 mL of the 6% solution </span>
<span>C. 140 mL of the 3.5% solution and 60 mL of the 6% solution </span>
<span>D. 120 mL of the 3.5% solution and 80 mL of the 6% solution
</span>
Let fraction of 3.5% in final solution be p.
<span>p * 3.5 + (1 - p) * 6 = 4.5 </span>
<span>3.5p + 6 - 6p = 4.5 </span>
<span>2.5p = 1.5 </span>
<span>p = 3/5 </span>
<span>3/5 * 200 = 120 </span>
<span>Therefore the answer is B. 120 ml of 3.5% and 80 ml of 6%.</span>
Answer:
<h2>The answer is 615 m²</h2>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius
From the question
r = 14 m
π = 3.14
The area of the circle is
A = 3.14 × ( 14 ) ²
= 3.14 × 196
= 615.44
We have the final answer as
<h3>615 m² to the nearest whole number</h3>
Hope this helps you
