Answer:
0
Step-by-step explanation:
Slope can be conceptualized as rise over run.
To get rise, you can see the difference between the two 'y' coordinates. In this case, it's 0 (-5 and -5). At this point, since the numerator of our [tex]\frac{rise}{run}[/tex] fraction is 0, you know it's just gonna be 0 no matter the value of the run.

When a number is decreased by 30 % of itself, the result is 14. What is the number?
Answer: 20
Step-by-step explanation:
We set up the equation.
Let the number = x
x-0.3*x = 14
0.7x = 14
x = 20
Your friend is going to buy a used car. The one he is considering costs $4000 and will lose value at a rate of 13% per year. How much less will it be worth in 3 years?
13% of $4000 is $520
If the $4000 car loses value at a rate of 13% each year for 3 years
$520 x 3 = $1560
Subtract this amount from $4000
$4000 - $1560 = $2440
Answer: In 3 years, the used car will be worth $2440 in 3 years

"A city official is modeling the demand for bus transportation as a function (,) of two variables:
= price of a daily bus ticket in $, = price of parking per day in a downtown garage in $.
She hypothesizes that demand varies inversely as and directly as 100^2.
Answer the following questions considering that with a daily bus ticket cost of $0.50 and parking price of $6 per day, there are 7,200 bus riders using the bus transportation system.
1. Write the mathematical function describing the demand for bus transportation:
(,) = _"
I'm not sure how to set this up. Also not clear on what "the demand varies inversely as x and directly as 100y^2" means in this context.

A bank account earns 2% interest each year. Giselle uses the expression p +0.02p
to find how much money will be in the account after one year if she deposits p dollars.
Answer:
1.02 is the simplified answer and 102% is the answer to the next one
Step-by-step explanation:
The expression p+0.02p can also be written as 1p+0.02p.
To combine like terms, add the coefficients.
1+0.02=1.02, so 1p+0.02p=1.02p.

The numbers are?
[tex]\bold{\huge{\pink{\underline{ Solution}}}}[/tex]
[tex]\bold{\underline{ Given :- }}[/tex]
The sum of two numbers is 25One number exceeds another by 5[tex]\bold{\underline{ To \: Find :- }}[/tex]
We have to find the two numbers.[tex]\bold{\underline{ Let's \: Begin:- }}[/tex]
Let the number be x
Therefore,
Another number be x + 5
According to the question,
[tex]\sf{ x + ( x + 5 ) = 25}[/tex]
[tex]\sf{ x + x + 5 = 25}[/tex]
[tex]\sf{ 2x + 5 = 25}[/tex]
[tex]\sf{ 2x = 25 - 5}[/tex]
[tex]\sf{ 2x = 20 }[/tex]
[tex]\sf{ x = 20/2}[/tex]
[tex]\sf{ x = 10 }[/tex]
Thus, The first number is 10
Therefore,
Another number will be
[tex]\sf{ = x + 5 }[/tex]
[tex]\sf{ = 10 + 5 }[/tex]
[tex]\sf{ = 15 }[/tex]
[tex]\sf{\red{Hence, \:The \:two \:numbers\: are \:10 \:and\: 15}}[/tex]

fill in the blanks
Answer:
There are 2 solutions because the square root of any positive real number will give us both a positive and negative number as a solution .
Answer:
There are 2 solutions because the square root of any positive real number will give us both a positive and negative number as a solution.
Step-by-step explanation:
[tex](x-4)^2-28=8[/tex]
Add 28 to both sides:
[tex]\implies (x-4)^2=36[/tex]
Square root both sides:
[tex]\implies x-4=\pm 6[/tex]

Question 2
A circle has a centre C (1,3)The end points of a diameter of the circle are A (-3,2k) and B (5,k)
Find the value of k, k
Answer:
k = 2
Step-by-step explanation:
We'll need the Midpoint Formula: the midpoint of a segment joining points [tex](x_1, y_1) \text{ and }(x_2, y_2) \text{ is } \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex]. In other words, average the x's, then average the y's.
The midpoint of a diameter is the centre of the circle!
The midpoint of the segment joining (-3, 2k) and (5, k) is
[tex]\left(\frac{-3+5}{2}, \frac{2k+k}{2} \right)=\left(1,\frac{2k+k}{2}\right)=\left(1,\frac{3k}{2}\right)[/tex]
That last expression is the centre of the circle; it is the same as (1, 3).
[tex]\left(1,\frac{3k}{2}\right)=\left(1,3\right)\\\frac{3k}{2}=3\\3k=6\\k=2[/tex]
Natalie has 412 apples that she must package into bags. Each bag must hold 8 apples. Natalie divides 412 by 8 and gets an answer of 51 R 4. What is the correct interpretation of R 4 for this situation? 1. Natalie can fill 4 more bags after filling 51 bags. 2. Natalie has 4 bags left after filling 51 bags. 3. Natalie has 4 apples left after filling 51 bags. 4. Natalie can fill at most 51 bags with 4 apples each.
Answer:
3.
Step-by-step explanation:
The answer is 51 R4, meaning that 54 bags HAVE been filled and 4 apples are the remainder. Therefore, there are 4 apples that have not been bagged and Natalie would need another bag to bag all the apples.

Which number line shows the solution to
11x + 14 < –8?
Answer:
D
Step-by-step explanation:
11x + 14 < -8
Cancel the addition by subtracting
11x + 14 - 14 < -8 - 14
11x < -22
11x / 11 < -22/11
x < -2
Therefore, the answer is D

Volume = 4.1867*10^3
Volume = 4186.7 yards^3
pls can u gus tell me the ans and explanation
Answer:
2325 mL
Step-by-step explanation:
Let x = total volume of the tank. When we fill 4/5 of water into the tank, the amount of water we have can be expressed by 4x/5. Then we only keep 1/3 of that amount (poured away 2/3 of the water), so the amount of water is 4x/15. Thus we set up the equation like this:
4x/15 = 620
4x = 9300
x = 2325
Thus the tank can contain a maximum of 2325 mL.
What is the total price of an $18.97 item plus 8% slaes tax?
Answer:
$20.49
Step-by-step explanation:
8% = 8/100 = 0.08
Therefore, 8% of 18.97 = 0.08 x 18.97 = 1.5176
So the total price = 18.97 + 1.5176 = 20.4878 = $20.49
Alternatively,
108% = 108/100 = 1.08
18.97 x 1.08 = 20.4878

960.8
Answer:
690.8
Step-by-step explanation:
I've done this one before
Answer:
690.8 sq units
Step-by-step explanation:
Surface Area(cyl) = 2πrh+2πr²
SA = 2(3.14)(5)(17) + 2(3.14)5²
SA = 6.28(85) + 25(6.28)
= 533.8 + 157
= 690.8
Find the area of the composite figure.
Answer:
132 square feet
Step-by-step explanation:
The formula for the area of a triangle is 1/2 * b * h. B stands for base and h stands for height. 1/2 multiplied by the base, 10, is 5. We then multiply 5 by 12 which is 60. Let's look at the rectangle now. The area of a rectangle is length by width. The length is 12ft and the width is 6ft. 12 * 6 = 72. 72+60=132 square feet.
