what is the value of the expression when s=2 and t=1.5 -3|5-s3|+3t
Answer:
The value of the given expression is -4.5
Step-by-step explanation:
We need to find the value of the expression [tex]-3|5-s^3|+3t[/tex] when s=2 and t=1.5
Putting the values of s and t in the given expression.
So,
[tex]-3|5-s^3|+3t=-3|5-(2)^3|+3\times 1.5\\\\=-3|5-8|+4.5\\\\=-3|-3|+4.5[/tex]
We know that, |-a|=a
So,
[tex]=-3|-3|+4.5\\\\=-3(3)+4.5\\\\=-9+4.5\\\\=-4.5[/tex]
So, the value of the given expression is -4.5
Answer:
-13.5 is the correct answer.

A repair bill for your car is $553. The parts cost $265. The labor cost is $48 per hour. Write and solve an equation to find the number of hours of labor spent repairing the car. Record the solution (answer),
Answer:
6 hours
Step-by-step explanation:
Let the labor hours be x.
The bill comprises of parts cost plus labor cost. Labor cost is hours times the cost per hour. Then we have equation:
265 + 48x = 55348x = 553 - 26548x = 288x = 288/48x= 6So the answer is 6 hours.
I have ₹355.50 in my pocket . i purchased a shirt for ₹ 235.50 and a pair of socks for ₹ 22.65. How much money is left with me now ?? ONLY FULL METHOD NO DIRECT ANSWER PLS
Answer:
97.35
Step-by-step explanation:
355.5 - 235.5 -22.65
I am subtracting 235.5 and 22.65 from 355.5 because I am spending that much money on the things.
=> 355.5 - 235.5 - 22.65
=> 120 - 22.65
=> 97.35 rupees
So, 97.35 rupees is left

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is atmosphere nitrogen, making it the largest source of nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems.

If 26.97 ÷ 6.3 is written in long division form as long division set up where 63 is on the outside of the division symbol and 26970 is on the inside so that the divisor is written as a whole number, where should the decimal point be placed in the dividend?
Answer:
The decimal point should be placed between 9 and 7
i.e
269.70
Step-by-step explanation:
In Long division method, the formula is given as:
Dividend ÷ Divisor = Quotient
We were given
26.97 ÷ 6.3
26.97 = Dividend
6.3 = Divisor
We are told in the question that:
as long division set up where 63 is on the outside of the division symbol and 26970 is on the inside so that the divisor is written as a whole number,
This means, since the Divisor 6.3 is made into an whole number = 63
It means 6.3 was multiplied by 10
6.3 × 10 = 63
In Long division, whatever rule is applied to the Divisor must be applied to the Dividend.
Since 6.3 was multiplied by 10 = 63(whole number), then the dividend must be multiplied by 10
Dividend = 26.97 × 10 = 269.7
Therefore, the place where should the decimal point be placed in the dividend is between 9 and 7
= 269.70
Answer: Between the 9 and the 7

Hey, Would someone help me on this. Thanks xx... Here are 4 digits: 6 3 5 9 Using only 3 of the digits write a number that is closest to 600. You can only use each of the digit once . GCSE MATHS NUMBER QUESTION
Answer:
596
Step-by-step explanation:
closest to 600.
this means we can narrow the first digit of all 5he three digits to be either 5 or 6:
5_ _
or
6_ _
however, when considering the closest number to 600 when starting with 6, we realise that we can only make 630.
when looking at starting with 5, we can make 590, much closer to 600.
so now, we have deduced it has to become 590
however, we can use 3 digits. so, using a 6, the next highest number, we can confidently rest our case.

30+2k+5k=100
What is k?
Answer:
k = 10
Step-by-step explanation:
30+2k+5k=100
Combine like terms
30 + 7k = 100
Subtract 30 from each side
30+7k-30 = 100-30
7k = 70
Divide each side by 7
7k/7 = 70/7
k = 10
Answer:
k=10
Step-by-step explanation:
We are given the equation:
30+5k+2k=100
We want to find k, therefore we must isolate k on one side of the equation.
First, combine like terms on the left side of the equation. 5k and 2k can be added together.
30+5k+2k=100
30+(5k+2k)=100
30+7k=100
30 is being added to 7k. The inverse of addition is subtraction. Subtract 30 from both sides of the equation.
30-30+7k=100-30
7k= 100-30
7k= 70
k is being multiplied by 7. The inverse of multiplication is division. Divide both sides by 7.
7k/7=70/7
k=70/7
k= 10
The solution to the equation 30+5k+2k=100 is k=10
Translate the following into an algebraic expression: The number that is 40% more than five more than a number a.
Answer:
The translation would be
X = 40% + 5 + A
Step-by-step explanation:
First, translate the words, is, more than and 'the number'.
Is means equals (=).
More Than means plus (+).
'the number' can be x.
Now, put it together.
X(The Number) =(Is) 40% +(more than) 5 +(more than) A(a number)
I hope this helps!!
The expression of the number that is 40% more than five more than a number A will be mathematically given as 40% + 5 + A.

One month, Ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby.
Together they worked 102 hours. Find the number of hours each person worked.
h
Isaac worked____
hours.
Ruby worked____
hours.
Svetlana worked____
hours.
Answer:
Isaac worked 12 hours
Ruby worked 18 hours
Svetlana worked 72 hours
Step-by-step explanation:
Here in this question, we are interested in knowing the number of hours each person worked.
We proceed as follows;
Let the number of hours Isaac worked be x hours.
From the question, we are told that Ruby worked 6 hours more than Isaac
So the number of hours Ruby worked will be;
(x + 6) hours
Also;
Svetlana worked 4 times as many as Ruby:
This means that we have to multiply the number of hours Ruby worked by 4 to get the number of hours that Svetlana worked;
So the number of hours Svetlana worked will be : 4(x + 6) hours
Since the three worked a total of 102 hours, to get the number of hours each worked, we need to add together the number of hours each individual put in to work and equate to 102;
Mathematically, that would be;
x + x + 6 + 4(x + 6) = 102
2x + 6 + 4x + 24 = 102
6x + 30 = 102
6x = 102-30
6x = 72
x = 72/6
x = 12 hours
So Isaac worked x hours = 12 hours
Ruby worked (x + 6) hours = 12 + 6 = 18 hours
Svetlana worked 4(x + 6) hours = 4(18) = 72 hours
Ralph is an electrician. He charges an initial fee of $32, plus $33 per hour. If Ralph earned $197 on a job, how long did the job take?
Answer:
5 hourss
Step-by-step explanation:
197-32= 165
165/33
Answer:
5 hours
Step-by-step explanation:
Ralph earned $197 in total but with an initial fee of $32 so,
197 - 32 = 165
$165 is the amount he made from the hourly fee alone. So let's divide the total by the hourly fee.
165 ÷ 33 = 5.
So the job took 5 hours.
You have $85 in your bank account. Each week you plan to deposit $7 from your allowance and $15 from your paycheck. The equation b=85+(15+7)w gives the amount b in your account after w weeks. How many weeks from now will you have $210 in your bank account?
Answer:
6 weeks
Step-by-step explanation:
So the amount b we will have in our account w weeks from now is given by the equation:
[tex]b=85+(15+7)w[/tex]
To find out after how many weeks from now we will have $210, substitute 210 for b and solve for w:
[tex]210=85+(15+7)w[/tex]
Subtract 85 from both sides:
[tex]125=(15+7)w[/tex]
Add within the parentheses:
[tex]125=22w[/tex]
Divide both sides by 22:
[tex]w=125/22\approx5.68\approx6[/tex]
In other words, we will have $210 after approximately 6 weeks.

en un parque de diversiones,el túnel del miedo sube ahasta alcanzar una altura de 50 metros sobre el piso después, cae 65 m hacia un túnel subterráneo ¿cuál es la diferencia entre la elevación del túnel contra la del túnel subterráneo
Responder:
15mExplicación paso a paso:
Deje que el nivel del suelo del parque de atracciones sea cero. Si el túnel del miedo se eleva a una altura de 50 metros sobre el suelo, entonces la distancia desde el nivel del suelo hasta la altura de 50 m sobre el suelo será 50 + 0 = 50 m.
Del mismo modo, si el túnel cae 65 m en un túnel subterráneo, la distancia desde el nivel del suelo hasta la distancia de 65 m bajo tierra será de 65 m.
De ahí la diferencia entre la elevación del túnel y la del túnel subterráneo = 65 m - 50 m = 15 m
