Thanks ​

Answers

Answer:

[tex]\dfrac{7}{10}[/tex]

Step-by-step explanation:

We need to find a rational number between 3/5 and 4/5.

We can find a rational number between two fractions as :

[tex]\dfrac{a+b}{2}[/tex]

We have, a = 3/5 and b = 4/5

So,

[tex]\dfrac{\dfrac{3}{5}+\dfrac{4}{5}}{2}\\\\=\dfrac{\dfrac{7}{5}}{2}\\\\=\dfrac{7}{10}[/tex]

So, a rational number between 3/5 and 4/5 is equal to 7/10.

Angel is a high school basketball player. In a particular game, he made some free throws (worth one point each) and some two point shots. Angel made a total of 12 shots altogether and scored a total of 16 points. Graphically solve a system of equations in order to determine the number of free throws made, x,x, and the number of two point shots made, yy.

Answers

Answer:

w = 8, y = 4.

Step-by-step explanation:

i think this is right i am not sure

Answer:

[tex]x = 8 \\ y = 4[/tex]

Step-by-step explanation:

Let x be the number of one point shots, and y the number of two point shots.

We have

[tex]x + y = 12 \\ y = 12 - x[/tex]

And

[tex]x + 2y = 16[/tex]

Substituting the first equation in we get

[tex]x + 2(12 - x) = 16 \\ x + 24 - 2x = 16 \\ - x = - 8 \\ x = 8[/tex]

Since

[tex]y = 12 - x \\ y = 12 - 8 = 4[/tex]

A homeowner installs a solar heating system, which generates 20 savings at a rate of 300e t dollars per year, t years after installation. Find a formula for the total savings after t years. If the system cost 30000 dollars to install, when will the savings match the installation cost

Answers

Answer:

"35.84 years" is the appropriate solution.

Step-by-step explanation:

The given values are:

Rate of savings generation,

[tex]s'(t)=300e^{\frac{t}{20} }[/tex]

System cost to install,

= $30000

Now,

The total savings will be:

⇒  [tex]s(t)=\int\limits s'(t) \ dt[/tex]

On substituting the values, we get

⇒         [tex]= \int\limits 300e^{\frac{t}{20} } \ dt[/tex]

⇒  [tex]s(t)=\frac{300e^{\frac{t}{20} }}{\frac{1}{20} }+c[/tex]

When,

Savings = 0

t = 0, then

⇒  [tex]0=6000e^o+c[/tex]

⇒  [tex]c=-6000[/tex]

The formula will be:

⇒  [tex]s(t)=6000[e^{\frac{t}{20} }-1][/tex]

On putting the values in the above formula, we get

⇒  [tex]30000=6000(e^{\frac{t}{20} }-1)[/tex]

           [tex]5=e^{\frac{t}{20}}-1[/tex]

        [tex]e^{\frac{t}{20} }=6[/tex]

On taking log, we get

⇒  [tex]\frac{t}{20} =log \ 6[/tex]

      [tex]t=20 log 6[/tex]

        [tex]=35.84 \ years[/tex]  

Given the figure below, find the values of x and z.

Answers

Answer:

x = 12

z = 101

Step-by-step explanation:

Hello There!

First lets find z

Well the angle that has a measure of 79 degrees and angle z are supplementary angles meaning that the sum of the two is 180

So we can find the missing angle by subtract the given angle (79 in this case) from 180

180 - 79 = 101 so z = 101

Now lets find x

The angle that has a measure of 79 degrees and the angle labeled (6x+7) are vertical angles

If you didn't know vertical angles are congruent

That being said lets create an equation to solve for x

79 = 6x + 7

now we solve for x

step 1 subtract 7 from each side by

7 - 7 cancels out

79 - 7 = 72

now we have 72 = 6x

step 2 divide each side by 6

72/6=12

6x/6=x

we're left with x = 12

Which expression is equivalent to 4n(6n + 2m)?
A 24n + 4n + 2m
B (4n + 2m) x 6n
C 24n2 + 8mn
D 10n2 + 6mn

Answers

Answer:

c maybe

Step-by-step explanation:

4n(6n+2m)

24n²+8mn

Answer: C, 24n²+8mn

Step-by-step explanation:

So because 4n is on the outside of the bracket, you have to times everything on the inside of the bracket by 4n.

So, you do:

4n×6n=24n² (4×6=24 and n×n=n²)

4n×2m=8mn (4×2=8 and n×m=mn)

Then you add 24n² to 8mn like this:

24n²+8mn

Answers

Answer:

Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

Step-by-step explanation:

(0, -6) is the y-intercept, as x = 0.  Moving up 2, and right 1 represents the slope of the function. Going up is positive in the y direction, and going right is positive in the x direction.  

Drawing a line through the 2 points gives a sneak peak on the full function to be graphed

What is the equation of the line that passes through the point (7,-6) and has a slope of -2?

Answers

Answer:

y=-2+8

Step-by-step explanation:

The answer is y=-2+8 because of course the slope has to be -2 as you stated in your Question. So all you have to do is change the Y-Intercept until you reach the point. Since the Slope is negative, the Y-Intercept will rise until you reach your point. You may double check my answer to see if it is right, it is up to you.

He started taking long walks along the gates out front of his mansion, so he could catch a glimpse of the excitement of the town. One day while walking, he spotted a townsman outside the gate who looked just like him. The wealthy boy told the townsman of all the wonders and riches of the mansion, and the townsman spoke of all the gossip and business of his working life. They decided it might be fun to trade places. The townsman loved his new role as a wealthy young man. He ate fine food, watched wonderful entertainment, and wore stunning clothing. The wealthy boy loved his new role as a townsman. He explored the city streets, enjoyed all the sights and smells of the markets, and met all sorts of interesting people. Eventually, though, life at the mansion grew complicated. The wealthy boy's family wanted him to take over the family business, and the townsman grew stressed with his new responsibilities. The wealthy boy was having trouble too. He was having a hard time earning a living, and he was tired and hungry from working all day. The wealthy boy returned to the mansion gates to see the townsman. Life had looked more enchanting on the other side of the gates, but they returned to their rightful roles and were all the more thankful for the blessings of their own lives.Story 2There were two twin girls who dreamed of being married. The one girl was very intellectual. She loved to read, explore, and learn new things. The other girl was very athletic, and she wanted a husband that shared her same interest in sport and activity. The intellectual twin decided to marry a man who had been an explorer. He had fascinating tales of his travels. The athletic sister decided to marry a very competitive, loving, romantic young man who had a passion for hunting and sport. Both twins were very pleased with their choices and fell much in love with their respective husbands. Eventually though, their love began to fade. The athletic twin grew tired of being in constant competition with her husband. The intellectual twin's brain was being exhausted by the constant learning and testing. The twin sisters decided they would trick their husbands and make a switch. At first, the intellectual sister loved all the attention and competition from her sporty new husband. The athletic sister loved learning of all sorts of new things and loved going on long walks and adventures with her new husband. Eventually, though, the twins were doubly exhausted by the pursuits of their new husbands. They longed to switch back to the familiarity and routine of their own lives. Even though their husbands seemed to be troublesome, they were familiar, and they shared the interests that were best suited to each twin sister.What is different about the plots of both stories? In Story 1, a wealthy boy and a poor townsman trade lives. In Story 2, two twin sisters trade husbands. In Story 1, a wealthy boy and a sporty twin trade lives. In Story 2, an intellectual twin marries a townsman. One story is about poor people becoming wealthy, and the other is about wealthy people becoming poor. One story is about two people who look nothing alike, and in the other story the characters look identical.
