It is a combination of 3 rectangles.

All dimensions are given apart from the middle one. The missing dimension is:

The total area is:

Id the base BCDE of the pyramid is a horizontal square w side lengths 12cm . The size of the angle between AB and the base of the pyramid is 62 degree.

Side of square of base BCDE =12cm

Area of base =12² =144cm²

Volume of pyramid = 768cm³

1/3 a² × h= 768

1/3 × 144 × h =768cm³

h =768 × 3 /144

h =16 cm

BD² =BC² +CD²

BD² = 12² + 12²

BD² = 288

BD =√288 cm

BD = 16.97cm

BD = 17cm

So,

BF = 1/2 BD

BF = 1/2 × 17

BF =8.5cm

So since ΔABF  is angle between AB  and base of pyramid

tan <ABF = Tan-1 (16/8.5) = 62°

Therefore the size of the angle between AB and the base of the pyramid is 62 degree.

A rectangle that is scaled to be 4 times the size of the given rectangle would have the dimensions of 27.6 x 20.8.

When a rectangle is said to be scaled to be a certain number of times more than the size of another rectangle, it means that both rectangles will have the same shape and orientation, but their dimensions will be different.

This difference will come from the change that the scale factor brought about. In this instance, the scale factor is 4 times which means that the second rectangle will be 4 times the size of the first.

The first dimension would be :

= 6 . 9 x 4

= 27.6 units

The second dimension would be:

= 5 . 2 x 4

= 20. 8 units

The gain percentage is 12.5%

First, let`s find the Cost price (C.P) of the sofa.

Let C.P of the sofa be x.

Now, according to the question:

x+ 7% of x=Rs.3852

x + (7/100 * x) = 3852

x + 0.07x = 3852

1.07x = 3852

x=3852/1.07,

x = Rs 3600.

Now the dealer sells it for Rs 4050.

so, the Formula for gain% is=(Selling price-Cost price/Cost price)x100

Gain %= (4050-3600/3600)x100

Gain%=(450/3600)x100

Answer:

-2 is not a solution of the inequality 6g - 14 > 21.

Step-by-step explanation:

To determine if -2 is a solution of the inequality 6g - 14 > 21, we need to substitute -2 for g in the inequality and see if it is true.

6g - 14 > 21

6(-2) - 14 > 21

-12 - 14 > 21

-26 > 21

This inequality is not true. Because -26 is not greater than 21.

Mary paid Social Security tax of $4,378.325 in 2000. This is calculated by multiplying 7.5% by the amount of income over the maximum taxable income of  $4,378.325.

The theory used in this question is the marginal tax rate, which is the tax rate that applies to the income earned over the maximum taxable income. In this case, the marginal tax rate is 7.5%, which is the Social Security tax rate.

Step 1: Calculate the amount of income over the maximum taxable income.

Maximum taxable income: $53,000

Income earned: $61,711

Amount of income over the maximum taxable income: $8,711 ($61,711 - $53,000 = $8,711)

Step 2: Calculate the Social Security tax.

Social Security tax rate: 7.5%

Amount of income over the maximum taxable income: $8,711

Social Security tax paid: $4,378.325 ($8,711 x 0.075 = $4,378.325)

Answer:

a. To find the cost to surround the forest with a fence, we first need to determine the perimeter of the forest. The problem tells us that the perimeter is 45 yd. To convert this to feet, we can use the conversion factor of 3 feet per 1 yard. So, the perimeter in feet is:

45 yd x (3 ft/1 yd) = 135 ft

Next, we need to multiply the perimeter by the cost per foot to install fencing. We're told this cost is $6 per foot, so we can calculate the cost as:

135 ft x $6/ft = $810

b. To determine which region costs more to prepare, we need to calculate the cost per square yard for both the grassland and the forest. We're told that the cost to prepare 1 square yard of grassland is $15 and the cost to prepare 1 square yard of forest is $25.

To find the total cost for the grassland, we'll multiply the area of grassland with the cost per square yard:

2400 yd x $15/yd = $36,000

To find the total cost for the forest, we'll multiply the area of forest with the cost per square yard:

60 yd x $25/yd = $1,500

We can see that the grassland cost $36,000 to prepare while the forest cost $1,500 which means Grassland costs more to prepare.

Answer:

0.01 %

Step-by-step explanation:

The interest rate is the percentage of the principal (the amount borrowed) that is charged as interest over a certain period of time.

To find the interest rate, we can use the formula:

Interest Rate = Interest / Principal x Number of days / 365

We know that the principal is 600$, the interest is 14.25$ and the number of days is 90

so we can substitute the values into the formula:

Interest Rate = 14.25 / 600 x 90 / 365

Interest Rate = 0.02375 * 90 / 365

Interest Rate = 0.0104

Rounded to the nearest thousandth, the interest rate is 0.010 or 0.01 %

If you save RM1,000 at the end of each of the next 5 years in a savings account paying 6 percent compounded annually, the future value or the amount you will accumulate after 5 years is RM5,637.09.

The future value is the compounded present value of the periodic deposits.

The future value formula or FV table can determine the accumulated future value of periodic investments.

We can also use an online finance calculator to determine the future value.

N (# of periods) = 5 years

I/Y (Interest per year) = 6%

PV (Present Value) = RM0

PMT (Periodic Payment) = RM1,000

Results:

Future Value (FV) = RM5,637.09

Sum of all periodic payments = RM5,000(RM1,000 x 5)

Total Interest = RM637.09

Thus, in 5 years, you will have an accumulated future value of RM5,637.09 in the savings account.

Answer:

Step-by-step explanation:

Ben has a piece of plywood that measures 1 yard on each side, and he cuts it into 6 equal pieces.

The width of each piece is 1/3 yard, and the length of each piece is 1/2 yard.

To find the area of each piece that Ben cuts, we can multiply the width and length of each piece:

Area = (1/3 yard) x (1/2 yard)

Area = (1/3) x (1/2)

Area = 1/6 yard^2

So each piece that Ben cuts has an area of 1/6 yard^2.

The product 1/2x1/3 relates to the model in that it represents the area of the piece. In other words, the length and width are multiplied to find the area of the piece.

In this case, we can see that Ben cuts the plywood into 6 pieces of equal area, which is 1/6 of a square yard.

We can start solving the problem by using the formula:

Hours worked = Total cost / Hourly wage

In this case, we know that Chris needs at least $320.00 for his class trip, and he earns $8 per hour working on the weekends. So, we can plug in these values into the formula:

Hours worked = $320.00 / $8.00

To solve this equation, we divide 320 by 8:

Hours worked = 40

So Chris needs to work 40 hours on the weekends to be able to go on the class trip.

I hope this helps :)

Answer:

----------------------------------------

Chris earns $8 per hour and he needs at least $320.00 for his class trip.

If he works h hours, he will get 8h dollars.
