7x+10y=5 solve for y

Aloiza [94]

$7x+10y=5\ \ \ |Subtract\ 7x\ from\ each\ side\\\\
10y=5-7x\ \ \ |Divide\ by\ 10\\\\
y=\frac{5-7x}{10}\\\\
y=\frac{1}{2}-\frac{7}{10}x$

A light plane flew from its home base to an airport 255 miles away. With a head wind, the trip took 1.7 hours. The return

ryzh [129]

The speed from home base to airport was:
$v=255miles/1.7h\ /:1.7\\v=150mph$
The speed from airport to home base was:
$v=255miles/1.5h\ /:1.5\\v=170mph$
Average speed of plane was:
$\frac{170mph+150mph}{2}=160mph$
Average speed of wind was:
$x\ -\ wind\ speed\ (mph)\\150+x=170-x\ /+x\\150+2x=170\ /-150\\2x=20\ /:2\\x=10$
Answer: Average speed of plane was 160mph and average speed of wind was 10mph.

I hope I helped :D

Water use in the summer is normally distributed with a mean of 311.4 million gallons per day and a standard deviation of 40 mill

r-ruslan [8.4K]

Answer: 0.965

Step-by-step explanation:

Given : Water use in the summer is normally distributed with

$\mu=311.4\text{ million gallons per day}$

$\sigma=40 \text{ million gallons per day}$

Let X be the random variable that represents the quantity of water required on a particular day.

Z-score : $\dfrac{x-\mu}{\sigma}$

$\dfrac{350-311.4}{40}=0.965$

Now, the probability that a day requires more water than is stored in city reservoirs is given by:-

$P(x>350)=P(z>0.965)=1-P(z$

We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.

The population density is approximately 4 people per square mile

<h3>Calculating Population Density </h3>

From the question, we are to determine the population density

Population density is given by the formula,

$Population\ density = \frac{Number\ of\ people}{Land\ area}$

Number of people in the town = 12620 people

Now, we will determine the land area of the town

From the given shape,

Land area of the town = (60 × 65) - (25 ×40)

Land area of the town = 3900 - 1000

Land area of the town = 2900 square mile

∴ Population density = $\frac{12620}{2900}$

Population density = 4.3517

Population density ≅ 4 people per square mile

Hence, the population density is approximately 4 people per square mile
