a bathtub is draining at a consistent rate. after 2 minutes, it holds 28 gallons of water. three minutes later, it holds 7 gallons of water. write an equation that represents the number y of gallons of water in the tub after x minutes.
Answers
Answer:
y = 42 - 6 x
Step-by-step explanation:The slope-intercept formula is:
y = m x + b,
or: y = b - m x, since the rate is negative.
For the 1st formula we have: y = 30 and x = 2
For the 2nd formula: y = 12 and x = 5 ( because: 5 = 2 + 3, or : 3 minutes later, which can be confusing )
30 = b - 2 m
12 = b - 5 m
--------------------
b = 30 + 2 m
12 = 30 + 2 m - 5 m
3 m = 18
m = 18 : 3 = 6
b = 30 + 2 * 6 = 30 + 12 = 42
y = 42 - 6 x
Which fraction converts to a repeating decimal number?
OA. 1/12
OB. 7/8
OC. 14/25
OD. 17/20
OE. 6/10
Answers
=======================================================
Explanation:
Using a calculator shows that
1/12 = 0.0833333.... where the 3's go on forever7/8 = 0.87514/25 = 0.5617/20 = 0.856/10 = 0.6We see that nearly all of the decimal values are terminating decimals. This means the decimals don't go on forever, so the decimals stop at some point.
Only 0.083333... goes on forever, so that's why 1/12 converts to a repeating decimal number.
----------------------
A way you can determine this without a calculator is to use long division. Or you could use the idea that if the denominator has prime factors other than 2 and 5, then the decimal will repeat forever.
Note how the denominators of the fractions for choices B through E all have prime factors of either 2s only, 5s only, or a mix of 2s and 5s. This fact is why we have terminating decimals here.
In contrast, 12 has prime factorization 2*2*3. That 3 as a prime factor is why the decimal repeats forever.
The only fraction that converts to a repeating decimal number is 1/12.
What is decimal?Decimal is a fraction whose denominator is a power of ten and whose numerator is expressed by figures placed to the right of a decimal point.
Given is to find a fraction that converts to a repeating decimal number.
Repeating decimals are the decimals of the form -
2.7777...
2.34343434...
2.43434343....
Now, we have the fractions and their corresponding decimal numbers as follows -
1/12 = 0.0833333333333333 : Yes7/8 = 0.875 : No14/25 = 0.56 : No17/20 = 0.85 : No6/10 = 0.6 : NoTherefore, the only fraction that converts to a repeating decimal number is 1/12.

John sells t-shirts. Plain shirts cost $5 and graphic shirts cost $7.
In order to match his product costs, he must make at least $1,200.
Answers
Okay so is your question like how many plain and graphic he needs to sell to get more than $1200??
For example if he sells 100 plain shirts(which will come up to $500) and 100 graphic shirts($700) the Total amount earned would be $1200, so we would need to sell at least 100 shirts of each or more to get to $1200.
Also if he sells 240 plain shirts he will get $1200
Or if he sells 172 graphic shirts he will get $1204.

Una compañía suministra electricidad. Cobra $100 mensuales fijos más 15 centavos por kilowatt hora. En los primeros 400 kilowatts suministrados en el mes y cobra 12 centavos por cada kilowatt hora que pase de 400 kilowatts en el mes. ¿Cuál es la función que define al costo?
Answers
Answer:
La función resultante es una función a trozos:
[tex]C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}[/tex]
Step-by-step explanation:
El coste total de la electricidad suministrada ([tex]C_{T}[/tex]), medida en pesos, es la suma del coste fijo ([tex]C_{F}[/tex]) y el coste variable ([tex]C_{V}[/tex]), medidas en pesos.
[tex]C_{T} = C_{F}+C_{V}[/tex] (1)
Ahora, tenemos que el coste fijo es $ 100 mensuales, así:
[tex]C_{F} = \$ \,100[/tex] (2)
Y el coste variable considera que se cobra 15 centavos por kilowatt-hora para los primeros 400 kilowatts-hora y 12 centavos por kilowatt-hora para cada kilowatt-hora que pase de 400 kilowatts-hora en el mes:
(i) Menos o igual que 400 kilowatts-hora:
[tex]C_{V} = 0.15\cdot x[/tex] (3)
Donde [tex]x[/tex] es la electricidad suministrada en kilowatts-hora.
(ii) Mayor que 400 kilowatts-hora:
[tex]C_{V} = 0.15\cdot (400)+0.12\cdot (x-400)[/tex]
[tex]C_{V} = 12+0.12\cdot x[/tex]
La función resultante es una función a trozos:
[tex]C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}[/tex]
The length of the rectangle is 3 times its width.
The perimeter of the rectangle is 16 inches.
.
Which of the following is a reasonable length for this rectangle?
Answers
Answer:
Since length is three times, hence it is 6 inches.
let the width be x.
then, length= 3x
perimeter= 16 inches.
perimeter of a rectangle = 2( L+B)
2(3x+x)=16.
3x+x= 16÷2
4x= 8
x= 2
since length=3x
hence, 3×2= 6 inches

Answers
Answer:
y = 3x + 10
Step-by-step explanation:
Given that,
Slope = 3
y intercept = 10
We need to write an equation of a line.
The slope-intercept form of a linear equation is given by :
y = mx + b
Where
m is slope and b is y-intercept
Putting all the given values,
y = 3x + 10

Tyler and frazer weigh a total of 23kg.tyler is 7kg heavier than frazer.How much do they each weigh
Answers
Answer:
Frazer is the 8kg and Tyler is 15 kg.
Step-by-step explanation:
Total 23kg. Take away the 7kg, that Tyler weighs more, is 16.
Half the 16 to get 8.
please mark as the brainliest
Tyler and frazer weigh a total of 23kg then Frazer weighs 8 kg and Tyler weighs 15 kg.
Now assume Frazer's weight as x.
According to the problem, Tyler is 7kg heavier than Frazer.
Hence, Tyler's weight will be x + 7.
Now We know that the total weight of both of them is 23 kg.
Therefore, the equation will be:
x + (x + 7) = 23
Simplifying the equation, we get:
2x + 7 = 23
Now, subtracting 7 from both sides of the equation, we get:
2x = 16
Dividing both sides by 2,
x = 8
So, Frazer weighs 8 kg.
Now, we can calculate Tyler's weight as:
x + 7 = 8 + 7 = 15 kg
Therefore, Tyler weighs 15 kg.
