Sarah runs a small business employing 12 members of staff. Each of Sarah's employees works from 08:30 - 17:00 Sarah pays her workers £8.75 per hour. Calculate Sarah's daily outgoings on wages.

Sasha will deposit $450 at 6% simple interest. The formula for calculating the balance of an account with simple interest is given by A = P(1 + rt), where A is the final amount, P is the initial principal balance, r is the annual interest rate (expressed as a decimal), and t is the time in years.

In this case, the initial principal balance P is $450, the annual interest rate r is 6% or 0.06 as a decimal, and the time t is 2 years. Plugging these values into the formula gives us:

A = 450(1 + 0.06 * 2)

Evaluating this expression gives us a final amount of approximately $477 in the account after two years.

Sasha will deposit the rest of her money ($850 - $450 = $400) at 2% compounded annually. The formula for calculating the balance of an account with annual compounding is given by A = P(1 + r/n)^(nt), where A is the final amount, P is the initial principal balance, r is the annual interest rate (expressed as a decimal), n is the number of times the interest is compounded per unit time (per year in this case), and t is the time in years.

In this case, the initial principal balance P is $400, the annual interest rate r is 2% or 0.02 as a decimal, n is 1 since it’s compounded annually, and the time t is 2 years. Plugging these values into the formula gives us:

A = 400(1 + 0.02/1)^(1 * 2)

Evaluating this expression gives us a final amount of approximately $416.16 in the account after two years.

Therefore, there will be approximately $60.84 more money in Sasha’s account at 6% simple interest than at 2% compounded annually after two years.

Answer:

(a) 3581 N

(b) 6.1 kJ

(c) 4.5 kJ

(d) 74.6%

Step-by-step explanation:

(a) To lift the piano straight up, we need to counteract the force of gravity acting on it. The force required can be calculated using the formula F = mg, where F is the force, m is the mass of the piano, and g is the acceleration due to gravity. So, F = (230 kg) x (9.81 m/s^2) = 3581 N.

(b) The work done in lifting the piano is given by the formula W = Fd, where W is the work done, F is the force required to lift the piano, and d is the height to which the piano is lifted. So, W = (3581 N) x (1.7 m) = 6.1 kJ.

(c) Using a ramp reduces the force required to lift the piano. The force required can be calculated using the formula F = mg sinθ, where θ is the angle of inclination of the ramp. We are given that the force required is 300 N and the length of the ramp is 15 m. So, sinθ = F/mg = 300/(230 x 9.81) = 0.1416. Therefore, θ = sin^-1(0.1416) = 8.13 degrees. The work done using the ramp can be calculated using the formula W = Fd, where d is the height to which the piano is lifted. Using trigonometry, we can find that the height to which the piano is lifted is 1.53 m. So, W = (300 N) x (15 m) x sin 8.13 degrees = 4.5 kJ.

(d) The efficiency of the ramp is the ratio of the work output to the work input, expressed as a percentage. The work output is the same as the work done using the ramp, which is 4.5 kJ. The work input is the same as the work done when lifting the piano straight up, which is 6.1 kJ. So, the efficiency of the ramp is (4.5/6.1) x 100% = 74.6%.

All 6 problems can be solved using the Pythagorean theorem using the following two rules

If x is the hypotenuse and a, b are the shorter sides then
[tex]x = \sqrt{a^2 + b^2}[/tex]

If x is one of the shorter sides and a (or b) is the other shorter side and c is the hypotenuse then

[tex]x = \sqrt{c^2 - a^2\\[/tex]  if a is the other shorter side

[tex]x = \sqrt{c^2 - b^2\\[/tex]  if b is the other shorter side

I will just demonstrate for  #1 , #2 and #6. You can figure out the reasoning behind the rest.

#1. x is the hypotenuse, 5 and 12 are legs(shorter sides)

# 2. x is one of the shorter sides (leg)

5 is the hypotenuse and 3 is the other shorter side

[tex]x = \sqrt{5^{2} - 3^{2}}\\\\x = \sqrt{5^{2} - 3^{2}}\\\\x = \sqrt{25 - 9}\\\\x = \sqrt{16}\\\\x = 4[/tex]

Answer:

To fill in the blank, let's first expand the left-hand side of the equation:

(2d-5)(2d-4)

= 2d * 2d + 2d * (-4) -5 * 2d -5 * (-4) (using the distributive property)

= 4d^2 - 8d - 10d + 20

= 4d^2 - 18d + 20

Now, we can compare this with the right-hand side of the equation, which is 4d^2 + blank d + 20.

Comparing the coefficients of the like terms, we can see that the blank should be filled with -18, since the coefficient of d on the left-hand side is -18 (from -8d - 10d) and the coefficient of d on the right-hand side is blank.

So, the filled-in equation becomes:

(2d-5)(2d-4) = 4d^2 - 18d + 20

The Dimensions of the tent are: Base of triangular face (b): 4.46 ft, Height of triangular face (0.5b): 2.23 ft, Length of tent (b + 1): 5.46 ft.

With two triangular bases and three rectangular sides, a triangular prism is a three-dimensional geometric form. The rectangular faces link the matching edges of the bases, which are connected by the parallel triangular bases. This produces a form with a triangular cross-section along the prism's length. The distance between the vertices of the triangle bases is referred to as the length, whereas the height of the prism is the perpendicular distance between the bases.

Given:

Volume of tent = [tex]63 ft^3[/tex]

Let's assume the base of the triangular face of the tent is "b" feet. The height of the triangular face is half of the base, so it would be "0.5b" feet.

The length of the tent is given to be 1 foot more than the base, so the length would be "b + 1" feet.

Mathematically, the volume of a triangular prism can be given by:

[tex]Volume = (1/2) * base * height * length[/tex]

Substituting the given values and rearranging the formula to solve for "b":

[tex]63 = (1/2) * b * (0.5b) * (b + 1)\\126 = b^2 * (0.5b) * (b + 1)\\0.5b^3 + 0.5b^2 - 126 = 0[/tex]

Solving this cubic equation, we get "b ≈ 4.46" (rounded to two decimal places).

The market's required rate of return for Samsung's common stock is 5.53%, rounded to two decimal points

What is meant by the rate of stock?

The rate of stock refers to the price at which a particular stock is being bought or sold in the stock market, which can vary based on supply and demand.

What is decimal?

A decimal is a number system that uses the base 10 and includes a decimal point to separate the integer part from the fractional part. It is commonly used in mathematics and everyday life for expressing fractions, percentages, and monetary values.

According to the given information

We can use the constant-growth dividend discount model to calculate the market's required rate of return for the stock. The model is:

Current stock price = Dividend next year / (Required rate of return - Dividend growth rate)

We know the current stock price is $216, the dividend next year is $1.14, and the dividend growth rate is 5%. We need to solve for the required rate of return.

216 = 1.14 / (r - 0.05)

Multiplying both sides by (r - 0.05), we get:

216(r - 0.05) = 1.14

Expanding the left side, we get:

216r - 10.8 = 1.14

Adding 10.8 to both sides, we get:

216r = 11.94

Dividing both sides by 216, we get:

r = 0.0553 or 5.53%

Therefore, the market's required rate of return for Samsung's common stock is 5.53%, rounded to two decimal points

b)There are 35 ways to select three women from the group of seven women.

c) The probability that the selected group consists of all women is 0.122 or approximately 12.2%

What is probability?

Probability is the measure of the likelihood or chance that an event will occur, expressed as a number between 0 (impossible) and 1 (certain), or as a percentage between 0% and 100%. It is used to quantify uncertainty and make predictions in various fields such as mathematics, statistics, physics, engineering, economics, and social sciences

a. The total number of ways to select three people from a group of 13 is given by the combination formula,

C(13, 3) = 13! / (3! × (13 - 3)!) = 286

Therefore, there are 286 ways to select any three people from the group of 13.

b. The number of ways to select three women from a group of seven women is given by the combination formula,

C(7, 3) = 7! / (3! × (7 - 3)!) = 35

Therefore, there are 35 ways to select three women from the group of seven women.

c. To find the probability that the selected group consists of all women, we need to find the number of ways to select three women from the group of seven women and divide it by the total number of ways to select three people from the group of 13:

P(all women) = C(7, 3) / C(13, 3) = 35 / 286 = 0.122

The length of the side DC is 10.099 units.

Similar triangles are those triangles whose corresponding sides are in the same ratio. And the corresponding angles measure the same. It is denoted by the ‘~’ symbol.

Given that DE is parallel to AB. Therefore, the two triangles, ΔCDE and ΔABC are similar to each other.

For a similar triangle, the ratio of the corresponding sides are in the same ratio, therefore, it can be written as,

DC/AC = DE/AB = CE/BC

Take the first two terms,

DC/AC = DE/AB

DC × AB = DE × AC

As the length of AB is the same as the length of DC,

DC × DC = DE × AC

f = -15

Step-by-step explanation:

Use algebra to solve!

f/3 + 22 = 17

f/3 = 17 - 22 (bring 22 to the other side, this changes the sign from plus to minus)

f/3 = -5 {because 17-22 = (-5)}

f = (-5) (3) {to eliminate 3 from the denominator of f, you do the opposite of division which is multiplication, so -5 times 3}

therefore, f = -5

You can also check this answer by putting it back into the original equation, -15/3 is -5 and then -5 + 22 = 17.

Answer:

x = 115°

Step-by-step explanation:

The interior angle adjacent to the 115° angle measures:

180° - 115° = 65°

x is an exterior angle, so x = 65° + 50°

x = 115°

Answer:

115

Step-by-step explanation:

X has to be supplementary to that adjacent angle, so first the angle next to the 115 has to be defined. 180-115 (as the must be supplementary) is 65. 65+ 50= 115, which should be x. The 2 opposite angles will equal the opposite outside angle. Hope this helps!

If the scale of the drawing is 8 inches : 7 feet, this means that for every 8 inches in the drawing, there are 7 feet in real life.

To find out length of the room is in the drawing, we need to set up a proportion:

8 inches / 7 feet = x inches / 21 feet

where x is the length of the room in the drawing.

We can cross-multiply and solve for x:

8 inches × 21 feet = 7 feet × x inches

168 inches = 7 feet × x inches
