An architect creates a drawing in which a rectangular desk is 11 inches long and 6 inches wide. The drawing is at a scale of 1 inch = 2 feet. what is the actual area, in square feet, off the desk

Hello there!

Answer:

15

Step-by-step explanation:

According to Exterior Angle Theorem for ∠С in ∆ ABC:

∠BAC + ∠ABC = ∠ACD

(5y + 3)° + (4y + 8)° = 146°

5y + 3 + 4y + 8 = 146

9y + 11 = 146

9y + 11 - 11 = 146 - 11

9y = 135

y = 15

Answer: The measure of each interior angle of a regular octagon can be found using the formula:

(n-2) x 180 / n

Where n is the number of sides in the polygon.

For Octagon, n=8

So we can substitute 8 for n in the formula:

(8-2) x 180 / 8 = 6 x 180 / 8

Therefore, each interior angle of the base of Octagon Towers measures 135 degrees.

Step-by-step explanation:

The equation that represent the situation is 16.25 = 50 - 6.75x.

The number of sandwich bought by the customer is 5.

A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches.  Let x represent the number of roast beef sandwiches.

Then we will find the  how many sandwiches the customer buys when the amount Used for Payment is $50 and change received is $16.25.

Therefore, using equation,

16.25 = 50 - 6.75x

where

Therefore, let's find the number of sandwich bought using the equation.

16.25 = 50 - 6.75x

16.25 - 50 =  - 6.75x

-33.75 = -6.75x

divide both sides by -6.75

x = -33.75 / -6.75

x = 5

Hence,

number of roasted beef sandwich bought = 5

Answer:

h = 3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 legs.

let h represent the hypotenuse , then

h² = 3² + 3² = 9 + 9 = 18 ( take square root of both sides )

h = [tex]\sqrt{18}[/tex] = [tex]\sqrt{9(2)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex] ← exact value

a) The compound interest rate is 75%

b) The simple interest rate is 12.5%

What is the interest?

We know that the interest is the money that accrues to an investment that have been made. We know that we can be able to determine the simple interest by the use of the formula.

A = P(1 + r/n)^nt

A = amount

P = principal

r = rate

n = Number of times compounded

Then we have;

2(1000) = 1000(1 + r)^8

Where n = 1

2 =  (1 + r)^8

0.693 = 8 ln(1 + r)

e^0.693/8= (1 + r)

r = 1 - e^0.693/8

r = 0.75 or 75%

For the simple interest rate;

I = PRT/100

I = A - P

I = 2000 - 1000 = 1000

1000 = 1000 * R * 8/100

R = 1 * 100/8

R = 12.5%

The correct first step in solving the inequality –4(2x – 1) > 5 – 3x is option A: Distribute –4 to get –8x + 4 > 5 – 3x.

This is because we are trying to solve for x, so we need to get x on one side of the inequality and all the other terms on the other side. In order to do this, we need to apply distributive property of multiplication over addition, which means we need to multiply the -4 with the 2x-1. By doing this we get -8x + 4 > 5 - 3x. This can help us to move forward in solving the inequality. This is the correct first step as it gets us closer to isolating the variable x on one side of the inequality.

After this step, we can further simplify the inequality by adding or subtracting similar terms to get the final solution.

It is important to remember that when solving inequalities we need to be careful with the signs, specially when dividing or multiplying by a negative number, as it might change the direction of the inequality.

A solution is a homogeneous mixture of two or more components in which the size of particle is smaller than 1 nm.

Normal examples of solutions are sugar in water and salt in water solutions, soda water, etc. In a solution, all the components emerge as a single phase. There is particle similarity i.e., particles are evenly allocated.

This is why a whole bottle of soft drink has the same flavors throughout.

Following are the property of solution:

1. It is a homogeneous mixture.

2. Its particles are too small and have a diameter of less than 1 nm.

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

The distribution of the data is skewed right, which means that the data is not evenly distributed across the range of values.

To calculate the skewness, we can use the formula Skewness = (Mean - Mode) / Standard Deviation. In this case, the mean is 599.2 seconds, the mode is 590 seconds, and the standard deviation is 110.88 seconds. Plugging these values into the formula, we get Skewness = (599.2 - 590) / 110.88 = 0.8094. This indicates that the data is skewed right, as the skewness is greater than 0. A right-skewed distribution typically occurs when the majority of data points are closer to the minimum value, while there are fewer data points near the maximum value. This can be seen in the graphical summary, where the majority of the data points are clustered around the lower end of the range and the tail extends to the right.

Answer: 85 ÷ 5 = 17

Step-by-step explanation: We can simply find whatever division problem that has a quotient of 17 by multiplying 17 by something. So, I chose to do 17 * 5. That equals 85. Now to turn this into a division problem, we just take the product and divide it by a number other than 17 (5 in our case) so, it would look like 85 ÷ 5. That is 17. The way to check is by taking the 17 and multiplying it by the number in the middle (5). We get 85, making this statement true. I hope this helped!

Jerry has been doing it-up for number of 10 days , not counting the first day.

n + 14 = 33

n = 19 days

We know that Jerry did 15 it-up on the first day and 33 it-up today. Therefore, we can subtract 15 from 33 to get the total number of it-up that Jerry did over the past few days.

33 - 15 = 18e

We know that Jerry did 2 more it-up each day, so we can divide 18 by 2 to get the number of days.

18 / 2 = 9

Finally, we need to add 1 to the result to account for the first day.

9 + 1 = 10 days
