the value of the expression when t-32 degrees is what degrees
Complete Question:
The temperature doubled. Evaluate when t = 32 degrees.
The value of the expression when t = 32 degrees is degrees
Answer:
64 degrees
Step-by-step explanation:
Given
[tex]t = 32[/tex]
Required
Determine the value of t when it doubles
To do this, we simply multiply the current temperature by 2.
So:
[tex]t = 32[/tex] becomes
[tex]t = 32 * 2[/tex]
[tex]t = 64[/tex]
Hence, the temperature when it doubles is 64 degrees

Solve the equation using equivalent fractions. SHOW YOUR WORK.
6/10 - 1/5 + 1/4
Answer:0.65
Step-by-step explanation:
Firstly, we convert the fractions into decimals:
6/10=0.6
1/5=0.2
1/4=0.25
We then get : 0.6 - 0.2 + 0.25
0.6-0.2=0.4
0.4+0.25=0.65
Please help, this chapter was on derivatives...
================================================
Work Shown:
Before we can use derivatives, we need to find the value of s when (x,y) = (15,20)
s^2 = x^2+y^2
s^2 = 15^2+20^2
s^2 = 225+400
s^2 = 625
s = sqrt(625)
s = 25
-----------
Now we can apply the derivative to both sides to get the following. Don't forget to use the chain rule.
s^2 = x^2 + y^2
d/dt[s^2] = d/dt[x^2 + y^2]
d/dt[s^2] = d/dt[x^2] + d/dt[y^2]
2s*ds/dt = 2x*dx/dt + 2y*dy/dt
2(25)*ds/dt = 2(15)*5 + 2(20)*(10)
50*ds/dt = 150 + 400
50*ds/dt = 550
ds/dt = 550/50
ds/dt = 11
-----------
Side note: The information t = 40 is never used. It's just extra info.
write the slope - intercept form of the equation. PLEASE HELP. i will mark brainliest
Answer:
Step-by-step explanation: To find the equation of the perpendicular line, take the reciprocal of the slope with the opposite sign.
For example, the reciprocal of 4/3 is 3/4 and if it's negative, the opposite is positive.
The reciprocal of 2 is 1/2. and if it's positive, the opposite is negative.
The reciprocal of any number or fraction is whatever you multiply it by to get 1. 4 times 1/4 is 1 5/4 times 4/5 is 1. What about 1 ? 1 times 1 is 1. So one is its own reciprocal!

gets paid 15 per hour what is the minumim number of hours that joseph must work per week to make $450 per moth? (1moth=4weeks)
Answer:
Minimum of 7 1/2 hours ( 7 hours, and 30 minutes )
Step-by-step explanation:
Rate = money / time
time = money / rate
_____________
1 month = 4 weeks
1 week = 7 days
1 day = 24 hours
1 hour = 60 minutes
_____________
$15 / 1 hour = 1 day / 24 hours = 1 week / 7 days = 1 month / 4 weeks = $450 / 1 month.
$15 / 1 hour / 1 week = $450 / 1 month
$15 / 1 hour / 1 week = $450 / 4 weeks
$15 / 1 hour / 1 week = $112.5 / 1 week
$15 / 1 hour = $112.5
112.5 / 15 = 7.5 hours.

Solve the given system of equations utilizing either the substitution or addition method.
Answer:
Value of x=4 and y=-13/3
Step-by-step explanation:
We need to solve the systems of equations
[tex]5x+3y=7 \ and \ \frac{3}{2}x-\frac{3}{4}y =9\frac{1}{4}[/tex]
Solving using substitution method:
Let:
[tex]5x+3y=7---eq(1) \\ \frac{3}{2}x-\frac{3}{4}y =9\frac{1}{4}---eq(2)[/tex]
Find value of x from eq(1) and put in eq(2)
[tex]5x+3y=7\\5x=7-3y\\x=\frac{7-3y}{5}[/tex]
Put value of x in eq(2)
[tex]\frac{3}{2}(\frac{7-3y}{5}) -\frac{3}{4}y =\frac{37}{4}\\\frac{21-9y}{10} -\frac{3}{4}y =\frac{37}{4}\\Taking \ LCM\\\frac{21*2-9y*2-3y*5}{20} =\frac{37}{4}\\\frac{42-18y-15y}{20} =\frac{37}{4}\\42-33y=\frac{37}{4}*20\\42-33y=185\\-33y=185-42\\-33y=143\\y=\frac{143}{-33}\\y=-\frac{13}{3}[/tex]
Now, finding value of x by putting value of y in eq(1)
[tex]x=\frac{7-3y}{5}\\x= \frac{7-3(-\frac{13}{3}) }{5}\\x=\frac{7+13}{5}\\x=\frac{20}{5}\\x=4[/tex]
So, Value of x=4 and y=-13/3

Which phrase does not describe a rational number?
Select one:
repeating decimal
integer number
terminating decimal
О
non-repeating, non-terminating decimal
========================================================
Explanation:
Any rational number is of the form p/q, where p and q are integers and q is nonzero. So basically it's any fraction you can think of.
If a decimal terminates (ie stops) then it is a rational number.
For instance, 0.9 = 9/10 is rational
If a decimal repeats in some way, then it is rational
Eg: 0.0833333.... = 1/12
The dots after the 3 indicate the 3's go on forever.
So far, the facts mentioned allow us to rule out choices A and C. Choice B can be ruled out as well because any integer is always rational. We can easily prove it as such by writing the integer x as x/1.
A more concrete example could be writing the integer 7 as 7/1. So this shows 7 is rational and any integer is rational. Simply stick the integer over 1.
The only thing left at this point is choice D. Any non-repeating non-terminating decimal will be irrational. An example would be pi = 3.14159... which goes on forever without a pattern that repeats. Effectively the decimal digits of pi are more or less random. An irrational number is one that is not rational, and therefore cannot be written as a ratio of two integers.
which point on the number line represents the quotient 12 divided by -2

1.What is the core characteristic that defines a zero-based budget?
2.Bianca has take-home pay every month of $800. She anticipates having $675 of expenses in August.
3.In a zero-based budget, why is it important that she put the extra $125 in some budget category?
4.Where might you suggest Bianca budget that extra $125? Why?
5.Does using a zero-based budget mean that your bank account will hit $0 at the end of every month? Explain.
Say that Bianca has take-home pay of $800, she budgets every cent out at the start of the month, and she then she needs less gas money than expected in August. She no longer spends the full $65 she budgeted there. What should she do with the leftover?
Answer:
1. You account for every dollar you make to where your budget shows you have $0
2. She will have $125 leftover to budget out as she sees fit
3. If she does not account for it she may over spend or think she has extra money
4. I would put it in savings
5. No this is not what it means. This means that your paycheck will be able to cover your expenses.
6. You should put extra money in savings. You never know what will occur and savings can always help.
Step-by-step explanation:
Blanca has a savings of $125, she needs to allocate this amount to fulfill the zero-based budget conditions, as a saving she can allocate the remaining amount.
What is the zero-based budget?It is defined as the budgeting method that allows you to fix an amount for everything such as utility expenses, savings, and miscellaneous expenses In other words income minus all expenses plus savings should be equal to zero.
1) The core characteristic of the zero-based budget as follows:
Strategy is dependent on what each unit can provide for the price.Quick changes can be made in the budget anytime if it is required to do so.All the people of the organization can participate in the budgeting process.The purposes of each unit are in line with the corporate aspirations.2) Blanca has take-home pay every month = $800
Total expenses = $675
Savings = Income - Total expenses
= $800 - $675 ⇒ $125
We can assume Blanca has savings of $125 at the end of the month.
3) The extra amount = $800 - $675 ⇒ $125
According to a zero-based budget income minus all expenses plus savings should be equal to zero.
Therefore Blanca needs to allocate this amount($125) to some budget category.
4) Blanca has a total of $675 expenses she will have $125 as saving at the end of the month.
She should allocate this amount to savings because it will increase her wealth.
5) Zero-based budget does not mean that at the end of every month Blanca has zero dollars in her bank account because as per the definition zero-based budgeting means income minus expenses should be equal to zero. Blanca has savings and other emergencies funds in her bank account.
Thus, Blanca has a savings of $125, she needs to allocate this amount to fulfill the zero-based budget conditions, as a saving she can allocate the remaining amount.

Answer:
Terminating goes to 3
Repeating goes to 4
Rational goes to 1
Irrational goes to 2
Answer:
1. Rational Number
2. Irrational Number
3. Terminating Decimal
4. Repeating Decimal
Step-by-step explanation:
A Rational Number can be written as a ratio of two integers. For example, as a simple fraction. That leaves us for the answer to the second one as irrational. To terminate means to end, so a terminating decimal is a decimal that does not go on forever. Whereas, a repeating decimal continues repeating forever (or indefinitely).

Answer:
y = 3x - 9
Step-by-step explanation:
To write a line with a slope of 3, set the coefficient of x to be 3:
y = 3x
But notice, if we evaluate x when it is equal to 2, we get 2*3=6, but we want it to be -3. Therefore, we just subtract 9 from the equation:
y = 3x - 9
