Answer:
Step-by-step explanation:
The total cost of 3 bags of chips and 4 jars of salsa at a
store is $11.25. The cost of each bag of chips is $2.75.
Write an equation that can be used to determine the cost
,
X, of 1 jar of salsa.
Answer: 2.75(3) + 4x = 11.25
Step-by-step explanation:
It says each bag costs $2.75 and there are 3 bags so multiply those 2 and then subtract them from the total cost (11). What you get after you subtract is the total costs of the salsa so divide that by 4 to get the cost of each, in this case it doesn't ask so we leave it as 4x.
For a science experiment, Jack adds 1 tsp of salt to 3 tsp of water. Mika adds 4 tsp of salt to 9 tsp of water. Whose water is saltier?
The person whose water is saltier is Jack's water.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Jack adds 1 tsp of salt to 3 tsp of water.
This means,
3 tsp of water = 1 tsp of salt
Divide both sides by 3.
1 tsp of water = 1/3 tsp of salt
1 tsp of water = 0.33 tsp of salt ____(1)
Mika adds 4 tsp of salt to 9 tsp of water.
9 tsp of water = 4 tsp of salt
Divide both sides by 9.
1 tsp of water = 4/9 tsp of salt
1 tsp of water = 0.0092 tsp of salt ____(2)
From (1) and (2) we see that,
Jack's water is saltier.
Thus,
Jack's water is saltier.

Stefan sells Jin a bicycle for $137 and a helmet for $17. The total cost for Jin is 140% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make bying the bicycle and helmet to Jin? Stefan originally spent $
Answer:
Stefan originally spent $110.
Stefan made a profit of $44.
Step-by-step explanation:
Given that:
Stefan sold the bike and helmet for $137 and $17
Total amount = 137+17 = $154
This is 140% of the price Stefan originally paid.
Let,
x be the original price paid by Stefan
140% of x = $154
[tex]\frac{140}{100}x=154\\1.4x = 154\\\frac{1.4x}{1.4}=\frac{154}{1.4}\\x=110[/tex]
Therefore,
Stefan originally paid $110 for the bicycle and helmet.
Profit made by Stefan = 154-110 = $44
Hence,
Stefan originally spent $110.
Stefan made a profit of $44.
integration of dx/3sin^2 -4
Answer:
= 1/2 tan^(-1)(2 cot(x)) + constant
Step-by-step explanation:
Take the integral:
integral1/(3 sin^2(x) - 4) dx
Multiply numerator and denominator of 1/(3 sin^2(x) - 4) by -sec^2(x):
= integral-(sec^2(x))/(4 sec^2(x) - 3 tan^2(x)) dx
Prepare to substitute u = tan(x). Rewrite -(sec^2(x))/(4 sec^2(x) - 3 tan^2(x)) using sec^2(x) = tan^2(x) + 1:
= integral-(sec^2(x))/(tan^2(x) + 4) dx
For the integrand -(sec^2(x))/(tan^2(x) + 4), substitute u = tan(x) and du = sec^2(x) dx:
= integral-1/(u^2 + 4) du
Factor out constants:
= - integral1/(u^2 + 4) du
Factor 4 from the denominator:
= - integral1/(4 (u^2/4 + 1)) du
Factor out constants:
= -1/4 integral1/(u^2/4 + 1) du
For the integrand 1/(u^2/4 + 1), substitute s = u/2 and ds = 1/2 du:
= -1/2 integral1/(s^2 + 1) ds
The integral of 1/(s^2 + 1) is tan^(-1)(s):
= -1/2 tan^(-1)(s) + constant
Substitute back for s = u/2:
= -1/2 tan^(-1)(u/2) + constant
Substitute back for u = tan(x):
= -1/2 tan^(-1)(tan(x)/2) + constant
Which is equivalent for restricted x values to:
Answer: = 1/2 tan^(-1)(2 cot(x)) + constant

When you flip a based coin the probability of getting a tail is 0.39. What's the probability of getting head
Answer:
0.61 or 61 %
Step-by-step explanation:
Answer:
0.61
Step-by-step explanation:
0.39 is also 39%, the highest probability is always 100% unless it says otherwise, so our equation is:
1 - 0.39 = 0.61
So the probability of getting a head is 0.61 or 61%

Revenue from Monorail Service, Las Vegas In 2005 the Las Vegas monorail charged $3 per ride and had an average ridership of about 28,000 per day. In December 2005 the Las Vegas Monorail Company raised the fare to $5 per ride, and average ridership in 2006 plunged to around 19,000 per day.
a. Use the given information to find a linear demand equation.
b. Find the price the company should have charged to maximize revenue from ridership. What is the corresponding daily revenue?
c. The Las Vegas Monorail Company would have needed $44.9 million in revenues from ridership to break even in 2006. Would it have been possible to break even in 2006 by charging a suitable price?
Answer:
A)The required linear demand equation ( q ) = -4500p + 41500
B) $4.61
$95680.55
C) No it would not have been possible by charging a suitable price
Step-by-step explanation:
A) find the linear demand equation
given two points ; ( 3, 28000 ) and ( 5, 19000 )
slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )
= ( 19000 - 28000 ) / ( 5 - 3 ) = -4500
slope intercept is represented as ; y = mx + b
where y( 28000) = -4500(3) + b
hence b = 41500
hence ; y = -4500x + 41500
The required linear demand equation ( q ) = -4500p + 41500 ----- ( 1 )
p = price per ride
B ) Determine the price the company should charge to maximize revenue from ridership and corresponding daily revenue
Total revenue ( R ) = qp
= p ( -4500p + 41500 )
hence R = -4500p^2 + 41500p ------ ( 2 )
To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p to a quadratic equation R(p) = ap^2 + bp + c
where a = -4500 , b = 41500 , c = 0
hence p = [tex]-\frac{b}{2a}[/tex] = [tex]- \frac{41500}{2(-4500)}[/tex] = 4.61
$4.61 is the price the company should charge to maximize revenue from ridership
corresponding daily revenue = R = -4500p^2 + 41500 p
where p = $4.61
hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55
C) No it would not have been possible by charging a suitable price

Students are measuring the mass of an object in Science class. The mass is 38 grams. Danielle measured the mass at 40 grams. What was her percent error?
Answer:
5.26%
Step-by-step explanation:
Danielle measured the the mass at 40grams. ,Compared to 38 grams, there is a percentage increase.
Old Value = 38grams, New Value = 40grams
%Increase = 40-38/38 × 100%
%Increase = 5.26%
A local catering company ordered 15 pounds of chicken, 21 pounds of beef, and 7 pounds of lobster. The cost of the chicken was $2 per pound, the cost of the beef was $4 per pound, and the cost of the lobster was $12 per pound. What was the total cost of the order?
the total price of the catering company's order was $198.
To discover the total value of the order, we need to multiply the kilos of every type of meat via its respective cost in keeping with pound and then add those products together.
For the chook:
15 pounds x $2 per pound = $30
For the beef:
21 kilos x $4 per pound = $84
For the lobster:
7 pounds x $12 per pound = $84
Now, we add up the costs of each form of meat to find the total cost of the order:
$30 + $84 + $84 = $198
Consequently, the whole price of the catering company's order was $198.

Can you make a triangle with lengths 10,7,15
Answer:
yes
Step-by-step explanation:
Answer:
The formation of ∆ is possible .
Step-by-step explanation:
Three sides of triangle are given which are 10 , 7 & 15. And we need to determine whetherwecanmake a triangle with these three sides or not . So we know that ,
" Sum of any two sides of a triangle is Greater
than the third side "
Let ,
a = 10b = 7c = 15Here we will see by three cases. And the formation of triangle will be possible if and only of all the three cases are possible.
So , let's check ,
Case 1:-
→ a + b > c
→ 10 + 7 > 15
→ 17 > 15
Case 2:-
→ b + c > a
→ 7 + 15 > 10
→ 22 > 10
Case 3 :-
→ a + c > b
→ 10 + 15 > 7
→ 25 > 7
Since all the three cases are true Hence formation of ∆ is possible.
Hence the formation of triangle is possible .Need some help, ASAP if possible. TY in advance!

Rex is currently taking physics as one of his electives in school. His grade at the end of the year is determined by
the average of four exams, each worth 100 points. On his first test he got an 84, on his second he got a 86, and on
his third an 92. What must he score on his fourth exam to get an A (90%) in the course?
98
b. 90
C. 88
d. 86
a.
Please select the best answer from the choices provided
А A
D
Answer:
The answer is A) 98.
Step-by-step explanation:
Rex has to score 98 marks in his fourth exam to obtain a grade A in the course.
Calculations for the score in the fourth exam:Total marks in four exams = 100 + 100 + 100 + 100 = 400
Marks required for an A (90%) in four exams = 90% of 400
= [tex]\frac{90}{100}\times 400[/tex]
= 360
Rex scores in Ist, 2nd and 3rd exam = 84, 86 and 92
So the score to be obtained in 4th exam for an A = 360 - (84 + 86 + 92)
= 98
Therefore, Rex has to score 98 marks in 4th exam to get a grade A.
