Answer:
<h3>A. 1.15 x 10^2
</h3>
Step-by-step explanation:
Given the following;
Diameter of the sun ds = 1,391,000 kilometers
Diameter of the Venus dv = 12,100kilometers
Taking the ratio of both diameters;
Ratio = Diameter of sun/Diameter of Venus
Ratio = 1,391,000/12,100
Ratio = 13910/121
Ratio = 114.958
Hence ds/dv = 114.958
ds/dv = 1.149 *10^2
ds/dv = 1.15*10^2
ds = 1.15*10^2 dv
Hence the diameter of the sun is 1.15*10^2 larger than that of the venus.
Answer:
21 pairs of socks
Step-by-step explanation:
We can find out how much money Chang has to spend on socks by subtracting the price of sneakers from his total money to spend by solving 160 - 95. From that, we get our answer of $65 that Chang has to spend on socks. We can divide 65 by 3 to see how many pairs of socks he can buy and we get our answer of 21 pairs of socks.

Respuesta:
Por lo tanto, los valores de y correspondientes son 3, 2, 4 y 8
Explicación paso a paso:
Dada la función f (x) = -5x + 3
Cuando x = 0
f (0) = -5 (0) + 3
f (0) = 0 + 3
f (0) = 3
Cuando x = 1/5
f (1/5) = -5 (1/5) + 3
f (1/5) = -1 + 3
f (1/5) = 2
Cuando x = -1/5
f (-1/5) = -5 (-1/5) + 3
f (-1/5) = 1 + 3
f (-1/5) = 4
Cuando x = -1
f (-1) = -5 (-1) + 3
f (-1) = 5 + 3
f (-1) = 8
For this case we have to:
x: Represents the number of miles that can be traveled in a day
We have that the cost of daily car rental is given by the following expression:

If the person has a budget of $200 then we have to:

Thus, you can travel 496 miles in one day.
Answer:

Answer:
18mL of the 20% solution must be mixed with 10 mL of the 6% solution to
obtain the desired 15% solution
Step-by-step explanation:
Ignore all of the useless information til the last sentence: How many milliliters of the 20% solution must be mixed with 10 mL of the 6% solution to obtain the desired 15% solution?
Our goal is to find out how many mL of 20% solution is needed to mix with 10mL of 6% solution to achive a 15% solution.
An easy and simple way to do it is to create a system of equation:
We add in x mL of 15% solution(Which has x mL of water and 20%*x mL of salt)
The equation: 15%=(20%x+0.6)/(x+10)
After solving it we get x=18
Therefore:
18mL of the 20% solution must be mixed with 10 mL of the 6% solution to
obtain the desired 15% solution
Hope this helps, have a good day!
