Answer: x = 10

see in the picture, ΔACE has:

+) BF//AE

+) B and F are  midpoints.

=> BF is the median line of the triangle ACE

=> BF = 1/2. AE

=> AE = 2BF

Snow Dome Ski Resort has 65 inches of snow. It is currently snowing there at a rate of 1 inch per hour. Mt. Winterpark Ski Resort has 74 inches of snow. Currently it is snowing there at a rate of ½ inch per hour.

a) Write equations that show the amount of snow at each resort as a function of the number of hours of snow.

b) If the snow continues at this rate, when will Snow Dome have more snow than Mt. Winterpark? Show your solution process clearly.

Answers

Answer:

a) Equation for Snow Dome Ski Resort:

[tex]I_s = 65+t[/tex]

Equation for Mt. Winterpark Ski Resort:

[tex]I_m = 74+\frac{t}{2}[/tex]

b) After 19 hours, Snow dome will have more snow.

Step-by-step explanation:

Given that:

Initial snow at Snow Dome Ski Resort = 65 inches

Snowing rate at Snow Dome Ski Resort = 1 inch per hour

Initial snow at Mt. Winterpark Ski Resort = 74 inches

Initial snow at Mt. Winterpark Ski Resort = [tex]\frac{1}{2}[/tex] inch per hour

a) To write equations that show amount of snow at each resort.

Let the time in hours be represented by [tex]t[/tex].

Snow increased in [tex]t[/tex] hours by snowing at Snow Dome Ski Resort = [tex]1\times t = t[/tex] inches per hour

Snow increased in [tex]t[/tex] hours by snowing at Mt. Winterpark Ski Resort = [tex]\frac{1}{2}\times t = \frac{t}{2}[/tex] inches per hour

Equation for Snow Dome Ski Resort:

[tex]I_s = 65+t[/tex]

Equation for Mt. Winterpark Ski Resort:

[tex]I_m = 74+\frac{t}{2}[/tex]

b) Time at which Snow Dome has more snow.

Using the above equations, we can write the following inequality:

[tex]65+t>74+\dfrac{t}{2}\\\Rightarrow t-\dfrac{t}{2}>74-65\\\Rightarrow \dfrac{t}{2}>9\\\Rightarrow t>18\ hours[/tex]

After 18 hours have passed, they will have equal amount of snow.

After 19 hours, Snow dome will have more snow.

During one month, a homeowner used 600 units of electricity and 100 units of gas for a total cost of 390. The next month, 400 units of electricity and 250 units of gas were used for a total cost of $326. Find the cost per unit of gas.

Answers

Answer:

cost per unit of gas i.e y= 0.36

Step-by-step explanation:

Let cost per unit of electricity = x

and cost per unit of gas = y

The equations required will be:

[tex]600x+100y=390 ---- eq(1)\\400x+250y=326----eq(2)[/tex]

We need to find value of y i.e cost per unit of gas

Solving equations to find value of y

We will use elimination method

Multiply equation 1 by 4 and 2 by 6

[tex]2400x+400y=1560 ---- eq(1)\\2400x+1500y=1956----eq(2)[/tex]

Subtracting eq 1 from eq 2

[tex]2400x+1500y=1956----eq(2)\\2400x+400y=1560 ---- eq(1)\\- \ \ \ \ \ - \ \ \ \ \ \ \ \ \ \ -\\----------------\\1100y=396\\y=\frac{396}{1100}\\y=0.36[/tex]

Solving we get y=0.36

Putting value of y in eq(1) to find value of x

[tex]600x+100y=390\\600x+100(0.36)=390\\600x+36=390\\600x=390-36\\600x=354\\x=\frac{354}{600}\\x=0.59[/tex]

Value of x = 0.59

But we need to find only cost of unit of gas i.e y

So, cost per unit of gas i,e y= 0.36

What is the slope of (0,4) and (3,10)? Please helppppp a girl outt !

Answers

Answer:

M=6 OR slope=6

Step-by-step explanation:

Use slope formula

Answer:

The slope of the given line is 2

Step-by-step explanation:

Slope is defined as the change of y over the change of x or rise over run. This is calculated by subtracting the second set of vales from the first set of values.

For y:

We have 10 and 4 for the y coordinates (y is the second number in a coordinate set). We will subtract 4 from 10, to get a result of 6.

For x:

We have 3 and 0 for the x coordinates (x is the first number in a coordinate set). We will subtract 0 from 3, to get a result of 3.

Slope is 6/3 or 2/1

The slope of the given line is 2

Solve

Answers

Answer:

y=3x+3

Step-by-step explanation:

y=mx+b is slope intercept form

to find the slope(m) you need to plug your numbers into the equation y(2)-y(1)/x(2)-x(1)

which means subtract the Y's together and the X's together and put the quotient of the Y's on top. Note that you have to choose a set of number to be the first group and the other set as the second group

so (0-6)/(-1-1) = -6/-2 = 3

3 will be your slope. plug that and a set of your numbers into the slope intercept equation

0=3(-1)+b

0=-3+b

3=b

Then she walked home.
Ruth took 1 1/4 hours to walk home.
(b) At what time did Ruth get home?

Answers

Answer:

She got home at 12:35 P.M.

Step-by-step explanation:

She got to the library at 10:30 am.

She spent 50 minutes there

10:30 + 50 mins can be seperated to 30 mins and 20 mins

So, 30 mins goes to 11 and 20 mins more equals 11:20.

She took 1 1/4 hours to get home

1 hour more means 12:20, and since 1/4 of an hour is 15 mins,

12:20 + 15 = 12:35 P.M

Four teachers are planning for their communication with parents. The school in which they all teach has a beginning-of-year open house and all parents are invited. The attendance at the open house is typical for most schools. Some parents attend; others do not. Interim progress reports are also sent to parents midway in each grading period. Ryan Hurst prepares a letter to the parents that expresses his optimism about the coming school year, and in it, he describes his rules and procedures. He has a friend read the letter to be sure there are no spelling or grammatical errors in it. He also sends packets of students' work home every two weeks to be signed by the parents and returned. He periodically calls parents to tell them when their son or daughter has done exemplary work. Monica Winters sends home a letter of introduction to parents and expresses her enthusiasm about the coming school year. She also emails parents when a problem of misbehavior occurs and solicits parents' support in dealing with the problem. Denise Nixon gives each of the parents that attend the open house a handout that describes her rules and procedures, and she verbally expresses her optimism about the school year and how much she believes her students are going to learn. Jerry Conway sends a letter of introduction home to parents in which he describes his rules and procedures for the year. He also calls or emails parents in cases where problems with misbehavior occur, and he follows up with an additional call to let parents know about the progress their son or daughter has made.
