Answer:

198 hamburgers

Step-by-step explanation:

Because the additive inverse of multiplication is division and since the cheeseburger are three times the number of hamburgers you should divide by three to get how many hamburgers were sold. Hope this helps

Answer:

Profit % is 1.94% .

Step-by-step explanation:

The CP of both VCR and TV were same that is Rs 78,000 . So ,

[tex] => CP \ of \ the \ buyer \ = \ Rs78,000 \times 2 = Rs 156,000 [/tex]

As per Question , on one he made a loss of 4% and profit of 8% on the other .

And , the net SP would be ,

[tex] => Total \ SP \ = \ \dfrac{96}{100}\times Rs 78,000 + \dfrac{108}{100}\times Rs 78,000 \\\\=> Total\ SP = Rs 74,800 + Rs 84240 \\\\\boxed{\red{\bf => Total \ SP= Rs 159,040 }}[/tex]

So , here clearly SP > CP . So , there's a profit .Hence profit % would be :-

[tex] => Profit \% = \dfrac{ SP - CP }{CP}\times 100 \\\\=> Profit \% = \dfrac{Rs 159,040-Rs156,000}{Rs156,000}\times 100 \\\\=> Profit\% = \dfrac{3040}{156000}\times 100 \\\\\underline{\blue{\bf => Profit\% = 1.94 \% }}[/tex]

Answer:

6

Step-by-step explanation:

Rachel's cost = $35x + $15  

Taylor's cost = $25x + $75

When are the costs equal? Rachel's cost = Taylor's cost?

35x + 15 = 25x + 75

35x - 25x = 75 - 15

10x = 60

x = 6

Check Rachel's 6 month cost is: 35 x 6 + 15 = 225

Check Taylor's 6 month cost is 25 x 6 + 75 = 225

Answer:

uhm, i'm pretty sure it would be 1,128 because between each term is 13 units, and the first three terms are given. and 89-3 is 86. and 86*13=1,118. since the last term was 10, you need to add 10 to that, making your answer 1,128

Answer:

(4, 0)

Step-by-step explanation:

3x + 4y = 12

2x - y = 8

8x - 4y = 32

11x = 44

x = 4

y = 0

Answer: the ordered pair is (4,0)

Step-by-step explanation:

Answer:

[tex]\\\qquad\quad\displaystyle\sf {:}\longrightarrow (y-5)2-(y-3)2=12 [/tex]

[tex]\\\qquad\quad\displaystyle\sf {:}\longrightarrow 2y-10-2y-6=12[/tex]

[tex]\\\qquad\quad\displaystyle\sf {:}\longrightarrow y's\:value\:is\:undefined [/tex]

Answer:

[tex] {(y - 5)}^{2} - {(y - 3)}^{2} = 12 \\ = ( {y}^{2} - 10y + 25) - ( {y}^{2} - 6y + 9) = 12 \\ = {y}^{2} - 10y+ 25 - {y}^{2} + 6y - 9 = 12 \\ = - 4y + 16 = 12 \\ = - 4y = 12 - 16 \\ = - 4y = - 4 \\ = y = \frac{ - 4}{ - 4} \\ = \boxed{y = 1}[/tex]

Answer:

f(3) = 10

Step-by-step explanation:

If x = 3 then fill in the x's on the original equation and solve;

f(x) = 2x + 4

f(3) = 2(3) + 4

2 x 3 = 6

6 + 4 = 10

So, f(3) = 10

Answer: 4/5 of a box of candy

Step-by-step explanation:

Justine sold 1¹/₅ times the ²/₃ of a box of candy that Grayson sold.

Justin sold;

= 1¹/₅ * ²/₃

= 6/5 * 2/3

= 12/15

= 4/5 of a box of candy

Answer:

AB=AD

4x=x+15

3x=15

x=15/3

x=5

Answer:

x = 5

Step-by-step explanation:

In a kite, two disjoint pairs of sides are congruent, then

AB = AD , that is

4x = x + 15 ( subtract x from both sides )

3x = 15 ( divide both sides by 3 )

x = 5

Complete question is;

A model for a company's revenue from selling a software package is R = -2.5p² + 500p, where p is the price in dollars of the software. What price will maximize revenue? Find the maximum revenue.

Answer:

Price to maximize revenue = $100

Maximum revenue = $25000

Step-by-step explanation:

We are told that:

R = -2.5p² + 500p, where p is the price in dollars of the software.

The maximum revenue will occur at the vertex of the parabola.

Thus, the price at this vertex is;

p = -b/2a

Where a = - 2.5 and b = 500

Thus:

p = -500/(2 × -2.5)

p = -500/-5

p = 100 in dollars

Maximum revenue at this price is;

R(100) = -2.5(100)² + 500(100)

R(100) = -25000 + 50000

R(100) = $25000

Answer:

X = 10

Step-by-step explanation:

This is an easy algebra equation that you may not know but the only thing you can do is to add 12 on both sides.  You should get 10 as a result.

Answer:

14

Step-by-step explanation:

14-12= -2

2 + 12=14

X=14 because if u subtract 14 and 12 u get -2 therefore the answer is 14

Answer:

16 kg

Step-by-step explanation:

Mass = (5x - 4) kg

Unit Price = 3x/kg

Total Price = mass * unit price

Total Price = (5x - 4)kg * 3x/kg

Total Price = 15x^2 - 12x

Total Price = 192

15x^2 - 12x = 192

15x^2 - 12x - 192 = 0

5x^2 - 4x - 64 = 0

ax^2 + bx +c = 0

ac = 5(-64) = -320

ac = -20 * 16

-20 + 16 = -4

5x^2 - 20x + 16x - 64 = 0

5x(x - 4) + 16(x - 4) = 0

(x - 4)(5x + 16) = 0

x - 4 = 0   or   5x + 16 = 0

x = 4   or   5x = -16

x = 4   or   x = -3.2

x cannot be negative because it would give a negative unit price, so we discard the negative answer.

x = 4

mass = 5x - 4 = 5(4) - 4 = 20  4 = 16

Step-by-step explanation:

Answer:

Value of cosθ is ±√7/3 .

Step-by-step explanation:

According to the Question , value of :

[tex]\red{\implies sin\theta = \dfrac{\sqrt2}{3}} [/tex]

And , we know the identity of sine and cosine as ,

[tex]\boxed{\pink{\sf\implies sin^2\theta + cos^2\theta = 1} }[/tex]

Using , this identity we have ;

[tex]\implies sin^2\theta + cos^2\theta = 1 \\\\\implies \bigg( \dfrac{\sqrt2}{3}\bigg)^2 + cos^2\theta = 1 \\\\\implies \dfrac{2}{9} + cos^2\theta = 1 \\\\\implies cos^2\theta = 1 - \dfrac{2}{9} \\\\\implies cos^2\theta = \dfrac{9-2}{9} \\\\\implies cos\theta = \sqrt{\dfrac{7}{9}} \\\\\underline{\boxed{\blue{\bf \implies cos\theta = \pm \dfrac{\sqrt 7 }{3}}}}[/tex]

Now , here since θ is in 2nd quadrant and in 2nd quadrant cos is negative . Hence ,the value of cos will be :

[tex]\boxed{\orange{\bf \implies cos\theta =-\dfrac{\sqrt7}{3}}}[/tex]

Answer:

6 Flower hats

Step-by-step explanation:

If you are asking for whole number answers, then the answer is 6 Flower hats.

check:

6X27=162 and 4 plain hats, 4X22=88, 162+88=250.

hope it helps!

The required number of hats with flowers is 6.

Given that,
Scooter the clown buys flower hats for $27 each and plain hats for $22 each. If he spends a total of $250 on hats, how many hats have flowers is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
let the hat with flower be x and the plain hats be y,
Total number of hats = 10
x + y = 10 - - - - - (1)
According to the question,
27x + 22y = 250 - - - - -(2)
Solving equation 1 and 2
gives
x = 6 and y = 4

Thus, the required number of hats with flowers is 6.

#SPJ2

Answer:

a) 3/5=12/20

b) 5/6=25/30

Step-by-step explanation:

a.) To find the answer you would first find how much it took to get to 20. 5  times 4 is 20. Then to find the numerator you would do 3 times 4 and that would be 12.

b) To find the answer you would first find how much it took to get to 30. So 30/6 is 5. Then you would divide 25 by 5 and you would get 5.
