Answer:

Step-by-step explanation:

20% of $30 = 40% of x

0.20 * 30 = 0.40 * x

[tex]\frac{0.2}{0.4}*30=x\\[/tex]

x = 15

Answer:

x = 116° , y = 20°

Step-by-step explanation:

The angles are x = 116° & y = 20°

When two angles are subtended by the same arc, the angle at the centre of a circle is twice the angle at the circumference i.e ∠O=2∠A

let the Points on the circumference be A,B,C then we have two traingles namely ΔABC & ΔOBC.

Given here ∠A=58°

therefore, by the circle theorem we get ∠O=116°

Again in  ΔOBC it is a isosceles triangle with its two sides equal to the radius of the circle, so ∠OBC = ∠OCB

∠OCB +∠OBC+∠BOC=180°

2 ∠OBC=180°-116°

2 ∠OBC=64°

∠OBC=32°

Again, in  ΔABC ∠C = 32° + 38° = 70°  & ∠B= y +32°

therefore, y + 32° + 70° + 58° = 180°

                                             y= 20°

Hence, the angles are  x = 116° & y = 20°

Answer:

New CP = Rs 387.5

Step-by-step explanation:

Cost Price = Rs. 500

Loss %age = 10% of 500

So, Loss = Rs 50

Finding the selling price:

Selling Price = CP - Loss

SP = 500 - 50

SP = Rs 450

Now, The fruit seller wants to gain a profit of 12.5% without changing the selling Price:

Firstly, Let's talk about the Profit :

Profit %age = 12.5% of 500

Profit = 12.5 * 5

Profit = Rs 62.5

He wants to gain a profit of Rs 62.5

So, The cost Price

The cost price would be reduced by Rs 62.5

New CP = 450 - 62.5

New CP = Rs 387.5

Answer:

x = [tex]\frac{8y-7}{3y-6}[/tex]

Step-by-step explanation:

Given

y = [tex]\frac{6x-7}{3x-8}[/tex] ( multiply both sides by 3x - 8 )

y(3x - 8) = 6x - 7 ← distribute left side

3xy - 8y = 6x - 7 ( subtract 6x from both sides )

3xy - 6x - 8y = - 7 ( add 8y to both sides )

3xy - 6x = 8y - 7 ← factor out x from each term on the left

x(3y - 6) = 8y - 7 ← divide both sides by (3y - 6)

x = [tex]\frac{8y-7}{3y-6}[/tex]

Step-by-step explanation:

($1238-$1039)×12=$2388

The setup for this problem is written as l(x,y)= f(x,y)+λg(x,y)

For example, a common economic problem is the consumer choice decision. Households are selecting consumption of various goods. However, consumers are not allowed to spend more than their income (otherwise they would buy infinite amounts of everything!!). Let’s set up the consumer’s problem:

Suppose that consumers are choosing between Apples (A) and Bananas (B). We have a utility function that describes levels of utility for every combination of Apples and Bananas.

11

A 2 B 2 = Well being from consuming (A) Apples and (B) Bananas.

Next, we need a set of prices. Suppose that Apples cost $4 apiece and Bananas cost $2 apiece. Further, assume that this consumer has $120 available to spend. The income constraint is

$2B+$4A≤$120

However, the problem requires that the constraint is in the form g(x, y)≥ 0. In

the above expression, subtract $2B and $4A from both sides. Now we have 0≤$120−$2B−$4A

g(A, B) Now, we can write out the lagrangian

11

l(A,B)= A2 B2 +λ(120−2B−4A)

f (A, B) g(A, B)

Step II: Take the partial derivative with respect to each variable We have a function of two variables that we wish to maximize.

Therefore, there will be two first-order conditions (two partial derivatives that are set equal to zero).

Answer: You would need 512 cubic centimetres

Step-by-step explanation: The first approach to this question would be to understand the properties of the shape given in the question.

If a cube has an edge with length 8 cm, then all edges measure 8 cm as well. That is one property of a cube. Hence, the length, width and height all measure 8 cm each.

The volume of a cube is given as follows;

V = L x W x H (and the answer is expressed as V³)

Since the length , width and height all measure 8 cm, the volume can simply be expressed as

V = L x L x L

V = L³

V = 8³

V = 512 cm³

Therefore to completely fill a cube with edge length of 8 cm you would need 512 cubic centimetres.

Answer:

See below in bold.

Step-by-step explanation:

h = -16t^2 + 120t + 10

To find the  height and time for maximum we convert to vertex form:

h = -16(t^2 - 7.5t) + 10

h = -16 [(t - 3.75)^2 - 14.0625] + 10

h = -16(t - 3.75)^2 + 225 + 10

h = -16(t - 3.75)^2 + 235

So the time to reach maximum height is 3.75 seconds and the maximum height = 235 ft.

x = 8.4/-2.4 = -84/24 = -3.5

The value of x in the equation is -3.5.

Division is the process of parting a number into equal parts using another number. The sign used to denote division is ÷.

In order to determine the value of x, divide 8.4 by -2.4

x = 8.4 / -3.5 = -3.5

Answer:

0.8224

Step-by-step explanation:

Data

z-score for x1:

z1 = (x1 - mean)/sd = (63 - 76)/10 = -1.3

z-score for x2:

z2 = (x2 - mean)/sd = (90 - 76)/10 =  1.4

The  proportion of wrist watch prices are between $63 and $90 is:

P(z1 < z < z2) = P(z < 1.4) - P(z < -1.3)

P(z < 1.4) = 0.9192 (see first picture attached)

P(z < -1.3) = 0.0968 (see second picture attached)

P(z1 < z < z2) = 0.9192 - 0.0968 = 0.8224
