Using proportions, it is found that the total percentage increase in the investor's stock account was of 6.2%.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The values of the stocks of Company A and Company B, after the increase are given, respectively, by:

The total values are given as follows:

The percent increase is given by the increase divided by the initial value and multiplied by 100%, hence:

P = (8668 - 8160)/8160 x 100% = 6.2%.

The total percentage increase in the investor's stock account was of 6.2%.

If the total cost of two umbrellas and one cap is is $20 the total cost for one umbrella and two caps is $16 then the price of one umbrella is $8 and price of one cap is $4.

Given that the total cost of two umbrellas and one cap is is $20 the total cost for one umbrella and two caps is $16.

We have to find the price of one umbrella and one cap.

We have to form equations first to find the price of umbrella and cap.

Equation of two variables look like ax+by=c. It can be a linear equation, quadratic equation or a cubic equation.

let the price of umbrella be x and price of cap is y.

We know that total cost is equal to price of one unit multiplied by the units.

According to question.

2x+y=20----------1

x+2y=16-----------2

Multiply equation 2 by 2 and then subtract resulted equation from equation 1.

2x+y-2x-4y=20-32

-3y=-12

y=-12/-3

y=4

put the value of y in equation 2 to get the value of x.

x+2y=16

x+2*4=16

x+8=16

x=16-8

x=8

Hence the price of one umbrella is $8 and the price of one cap is $4.

Answer:

  150 cm

Step-by-step explanation:

The total of exterior angles is 360°. We can use this fact to find the number of sides. The perimeter is the total length of all of the congruent sides.

The measure of an exterior angle of the regular polygon is the supplement of the adjacent interior angle:

  exterior angle = 180° -156° = 24°

The total of n of these angles is 360°, so n is ...

  24°×n = 360°

  n = 360°/24° = 15

The polygon has 15 exterior angles, hence 15 sides

The perimeter is the total length of the 15 congruent sides:

  P = 15×(10 cm) = 150 cm

The perimeter of the regular polygon is 150 cm.

Answer:

Step-by-step explanation:

I'll say that Sana's age is A, Rabia's age is B, and Saleem's age is C.

A + B + C = 47

Three years ago, everyone was three years younger, so we can write the expression as:

(A-3) + (B-3) + (C-3) = x

x is the total age three years ago.

The above equation is the same thing as:

A + B + C - 9 = x

Since we know that A + B + C is 47, we use that number instead.

47 - 9 = x

38 = x

So three years ago, their total age was 38 years old.

The number of cuts from a 20% length is 2 and the number of 20' angle are needed in order to have the 100 pieces is 5

From the information given;

The bricklayer needs = 100 pieces of angle

The number of cuts = 54

Length of cuts = 3/ 16'' Inches

a. To determine the number of cuts form a 20% length, we have to multiply the length by the percentage and by the initial number of cuts

= 20/ 100 × 3/ 16 × 54

= 0. 2 × 0. 1875 × 54

= 2. 0

The number of cuts would be 2

b. To determine the number of pieces of 20' angle to have 100 pieces we would divide the initial number of pieces by the angle

= 100/ 20

= 5 pieces

The number of pieces of 20' angle is 5

Thus, the number of cuts from a 20% length is 2 and the number of 20' angle are needed in order to have the 100 pieces is 5

Answer:

71.4% ( i think)

Step-by-step explanation:

If we translate 1 in 1.4 using what is described, it turns into (1/1.4)

Putting this into a calculator, we get 0.714286. Translated into a percent, that becomes 71.4286%

The probability that a member of the Senate (selected randomly) has a law degree is approximately 0.4167 or 41.67%.

When the odds are given as "1 in 1.4," it means that there is 1 chance of success (having a law degree) for every 1.4 chances of failure (not having a law degree).

To find the probability that a member of the Senate (selected randomly) has a law degree, you can use the formula:

Probability = 1 / (1 + Odds)

In this case, the odds are 1 in 1.4, so the probability is:

Probability = 1 / (1 + 1.4) ≈ 1 / 2.4 ≈ 0.4167

So, the probability that a member of the Senate (selected randomly) has a law degree is approximately 0.4167 or 41.67%.

Answer:

Width = 5.5ft, Length = 8ft.

Step-by-step explanation:

Area of Rectangle = Length x Width

Let w be the Width of the rectangle.

From the information given from the question,

Length = 2w - 3 (3ft less than twice the width)

Area of Rectangle = [tex](2w-3)w\\=2w^{2} -3w[/tex] = 44

Now we can solve for w to find the dimensions.

[tex]2w^{2} -3w-44=0[/tex] (Quadratic Equations)

We can use the Quadratic formula to find w.

[tex]w=\frac{-b+/-\sqrt{b^{2}-4ac } }{2a}[/tex]

Since a = 2, b = -3 and c = -44,

[tex]w=\frac{-(-3)+/-\sqrt{(-3)^{2}-4(2)(-44) } }{2(2)} \\= 5.5 or -4 (reject)[/tex]

We reject negative values here.

Therefore, the width of the Rectangle = 5.5ft

While the length of the rectangle = 2(5.5) - 3 = 11 - 3 = 8ft

Answer:

Step-by-step explanation:

We will substitute 600 to the y, since our final answer will be a number that makes the value of the stock reach $600.

log (y) = 0.30x + 0.296

Replacing y with 600, the equation becomes:

log (600) = 0.30x + 0.296

2.78 = 0.30x + 0.296

To move all the x and real numbers to different sides, we take 0.296 away from both sides to form:

2.78 - 0.296 = 0.30x

2.484 = 0.30x

x = 8.28

The approximation of 8.28 will be rounded to 8.3.

Then our final answer will be B: 8.3

7/16

Step-by-step explanation:

(2+5)/(2+3+5+6) = 7/16

The probability of either a yellow or a red ball being drawn if only one is drawn is 7/16.

The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event. The formula for probability is given by; P(E) = Number of Favourable Outcomes/Number of total outcomes.

According to the given question.

Numnber of yellow balls = 2

Number of green balls = 3

Number of red balls = 5

Number of black balls = 6

So,

The total number of balls in a bag = 2+ 3+ 5 + 6 = 16

And,

The sum of yellow and red ball = 2 + 5 = 7

Therefore,

The probability of either a yellow or a red ball being drawn if only one ball is drawn

= [tex]\frac{total\ number\ of \ red \ and \ yellow\ balls }{Total\ number\ of \ balls}[/tex]

[tex]= \frac{7}{16}[/tex]

Hence, the probability of either a yellow or a red ball being drawn if only one is drawn is 7/16.
