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:

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.

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:

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:

430 peaches

Step-by-step explanation:

Calculation for How many Peaches did he have to start

Using this formula

Peaches at hand=Remaining Peaches/(100%-Percentage of peaches sold)

Let plug in the formula

Peaches at hand=280/(100%-35%)

Peaches at hand=280/65%

Peaches at hand=430 peaches

Therefore the numbers of Peaches he have to start with is 430 peaches

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:

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.

Answer:

Another rational number

Step-by-step explanation:

Here, we want to get the type of number that should be added to a rational number to explain that the sum of two rational numbers is rational

What we simply have to do here is to add another rational number to the rational number we have already

By adding another rational number to the rational number we have, we will get another rational number

That has successfully proven what we are trying to prove

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:

AAA (angle angle angle) property.

Step-by-step explanation:

Maroon angle x in the first triangle is equal to the the Maroon angle x in the second triangle and the Orange angle y in the first triangle is equal to the Orange angle y in the second triangle with respect to the property of corresponding angles, and the third angle is 90° which is common between the two triangles hence AAA property is applied because all three angles are similar.

Answer:

m =40

Step-by-step explanation:

m/4 -3 = 7

Add 3 to each side

m/4 -3+3 = 7+3

m/4 = 10

Multiply each side by 4

m/4 *4 = 10*4

m = 40

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

Answer: 16 kg

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
