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.

Step-by-step explanation:

let 4x

6x

and x be the ratio

now

6x+4x+x=60

10x=60

x=60/10

x=6

again

6x

6×6

36

4x

4×624

and

x=6

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.

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.

B         [tex](f-g) (x)= \sqrt{\frac{x} {8} } -\frac{2}{x} +6[/tex]

[tex]f(x)= \sqrt{\frac{x} {8} } +11[/tex] ------------------(1)

[tex]g(x)=5+\frac{2}{x}[/tex] -----------------------(2)

Subtracting eq (2) from eq (1)

[tex]f-g= \sqrt{\frac{x} {8} } +11 - (5+\frac{2}{x} )[/tex]

[tex]f-g= \sqrt{\frac{x} {8} } +11 - 5 -\frac{2}{x}[/tex]

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

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%

The person whose water is saltier is Jack's water.

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.

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 ,

Here 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.

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

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.

Step-by-step explanation:

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.
