A scale drawing of a building needs to be made using the scale 1 in = 200 ft. How tall will the building in the scale drawing be if the building is 1200 ft tall?

Answers

Answer:

Step-by-step explanation:

Not very big.

1" = 200 feet

x = 1200 feet

1/x = 200/1200 Cross multiply

200 x = 1200 * 1 Combine

200x = 1200 Divide by 200

x = 1200 / 200

x = 6

Remark: the feet (one on each of the equal sign cancel out. All that is left is inches. So 6 is in inches.

During a drought, the cost of corn increases. Suddenly, gasoline costs $3.86 per gallon. A diesel truck uses 4 gallons to drive 60 miles. With the increased cost of gasoline, is it cheaper to drive the old truck or the diesel truck?

Answers

It is cheaper to drive the old truck, which costs $11.58 to drive 60 miles, compared to the diesel truck, which costs $15.44 to drive the same distance, given the current fuel prices.

Describe Algebraic Expression?

An algebraic expression is a mathematical phrase that consists of variables, numbers, and mathematical operations such as addition, subtraction, multiplication, and division. It is a combination of constants, variables, and operators that represent a value or a relationship between values.

For example, "3x + 5" is an algebraic expression where "3" and "5" are constants, "x" is a variable, and "+" is an operator. The expression can be evaluated by substituting a value for "x" and performing the necessary operations.

Algebraic expressions can also be simplified by combining like terms and using the rules of arithmetic to simplify the expression. For instance, the expression "2x + 3x" can be simplified to "5x" by adding the coefficients of the like terms "x".

Algebraic expressions are used extensively in algebra to represent equations and relationships between variables. They are also used in a wide range of mathematical and scientific applications, including physics, engineering, and finance.

To compare the cost of driving the old truck to the diesel truck, we need to know the fuel efficiency of the old truck. Let's assume that the old truck uses gasoline and has a fuel efficiency of 20 miles per gallon.

To drive 60 miles, the old truck will use 60/20 = 3 gallons of gasoline.

At $3.86 per gallon, the cost of 3 gallons of gasoline is 3 * $3.86 = $11.58.

The diesel truck uses 4 gallons of diesel to drive 60 miles. The cost of diesel is not given in the problem, so we'll assume it's the same as the cost of gasoline, $3.86 per gallon.

At $3.86 per gallon, the cost of 4 gallons of diesel is 4 * $3.86 = $15.44.

Therefore, it is cheaper to drive the old truck, which costs $11.58 to drive 60 miles, compared to the diesel truck, which costs $15.44 to drive the same distance, given the current fuel prices.

Step-by-step explanation:

A boy 1.5 m tall is standing 12 m away from a church building which has a tower on top of its roof. The top of the cross on the tower is 14.6 m away from the boy’s head (eyes). If the boy has to raise his eyes through an angle of 31° in order to see the top of the roof, calculate,Correct to the nearest degree, the angle through which the boy must raise his eyes to see the top of the cross on the tower.
Correct to one decimal place, the height of the top of the cross from ground.
Correct to one decimal place the height of the church building.

Answers

Answer:

1. $35^{o}$

2. 9.8 m

3. 8.7 m.

Step-by-step explanation:

1. Let the angle be represented by θ, so that:

Cos θ = $\frac{adjacent}{hypotenuse}$

= $\frac{12}{14.6}$

Cos θ = 0.82192

θ = $Cos^{-1}$ 0.8219

= $34.73^{o}$

θ = $35^{o}$

The angle through which the boy must raise his eyes to see the top of the cross on the tower is $35^{o}$.

2. Let the height from the boy's head to the top of the cross be represented by y, so that:

Sin $34.73^{o}$ = $\frac{y}{14.6}$

y = Sin $34.73^{o}$ x 14.6

= 0.5697 x 14.6

y = 8.32 m

The height of the top of the cross from the ground = 1.5 + 8.32

= 9.82 m

The height of the top of the cross from the ground is 9.8 m.

3. Let the height from the boy's head to the top of the building be represented by x, so that:

Tan 31 = $\frac{opposite}{adjacent}$

= $\frac{x}{12}$

x = Tan 31 x 12

= 0.6009 x 12

x = 7.21

The height of the church building = 1.5 + 7.21

= 8.71

The height of the church building is 8.7 m.

f(x)=18,000(.88)^x ; x represents the number of years since the car started to depreciate and 18,000 = the initial value of the car. What year will you recieve the car when the car value drops below $2,000? Please do a step by step

Answers

Answer:

After 17 years and 3 months

Step-by-step explanation:

Given function:

f(x)=18000(0.88)^x

We are looking for the value of x at f(x) < 2000

Solve the equation:

2000 = 18000(0.88)^x(0.88)^x = 2000/18000(0.88)^x = 0.1111log (0.88)^x = log 0.1111x = log 0.1111 / log 0.88x = 17.18

After 17 years and 3 months the car value drops below $2,000

Put f(x)=2000 and solve

2000=18000(0.88)^x2=18(0.88)^x1/9=(0.88)^xln(0.111)=xln0.88x=ln(0.111)/ln0.88x=17.18

x² -4x +1 = 0

Step-by-step explanation:

For roots p and q, the factored form of the equation is ...

(x -p)(x -q) = 0

The expanded form of this is ...

x² -(p+q)x +pq = 0

So, we can find the coefficients of the quadratic by finding the sum and product of the factors.

-b = (2 -√3) + 1/(2 -√3) = (2 -√3) +(2 +√3)/((2-√3)(2+√3)) = 4

c = (2 -√3)/(2 -√3) = 1

So, the quadratic is ...

460 square feet
640 square feet
960 square feet
1,280 square feet

Answers

The area οf the actual bridge deck in square feet is 1,280 square feet.

What is Area?

Area refers tο the measurement οf the size οf a twο-dimensiοnal surface, usually measured in square units such as square inches, square feet, οr square meters. It represents the amοunt οf space that is inside the bοundary οf a flat οbject οr shape.

The scale οf the drawing is 40:1, which means that the dimensiοns οf the scaled bridge deck are 40 times smaller than the actual bridge deck. Tο find the area οf the actual bridge deck in square feet, we need tο cοnvert the dimensiοns οf the scaled bridge deck frοm inches tο feet and then multiply by the square οf the scale factοr (40² = 1600).

The dimensiοns οf the scaled bridge deck in feet are:

24 inches = 2 feet

4 and 4/5 inches = 0.4 feet

Sο, the area οf the scaled bridge deck in square feet is:

2 feet x 0.4 feet = 0.8 square feet

Tο find the area οf the actual bridge deck in square feet, we need tο multiply the area οf the scaled bridge deck by the square οf the scale factοr:

Area οf actual bridge deck = 0.8 square feet x (40²) = 1280 square feet

Therefοre, the area οf the actual bridge deck in square feet is 1,280 square feet.

Answer:

Step-by-step explanation:

The scale factor indicates the actual bridge is 40 times larger than the drawing.

Increase the scale dimensions by the factor of 40.

24 times 40 = 960"

4.8 times 40 = 192" (I changed 4 4/5 to 4.8)

Area = length times width

960 times 192 = 184320 sq inches actual bridge deck in square inches

Divide 183320 by 144 (sq inches in a square foot) = 1280 sq feet

Abi takes out a loan that gathers compound interest. The table below shows the value of the loan over time. a) What is the rate of interest per annum? Give your answer as a percentage to 1 d.p. b) Work out the value of the loan 10 years after it starts. Give your answer in pounds (£) to the nearest 1p. Start After 1 year After 2 years £2500.00 £2645.00 £2798.41

Answers

(a) We can use the formula for compound interest to find the rate of interest per annum: A = P * (1 + r/n)^(n*t), where A is the final amount, P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years.

Using the table, we can see that the loan increases by a factor of 1.058 after 1 year and by a factor of 1.058/1.045 = 1.0124 after 2 years. Thus, we have:

1.058 = (1 + r/n)^(n*1)
1.0124 = (1 + r/n)^(n*2)

Dividing the second equation by the first, we get:

1.0124/1.058 = (1 + r/n)^(n*1)

Taking the nth root of both sides, we get:

(1 + r/n) = (1.0124/1.058)^(1/n)

Solving for r, we get:

r = n * [(1.0124/1.058)^(1/n) - 1]

We don't know the value of n, but we can make an educated guess that it's either 1 or 2, since the loan is increasing by roughly 5.8% per year. If we try n = 1, we get:

r = 1 * [(1.0124/1.058)^(1/1) - 1] = -0.0427

This is clearly not the correct answer, since the interest rate cannot be negative. If we try n = 2, we get:

r = 2 * [(1.0124/1.058)^(1/2) - 1] = 0.0574

This is a reasonable answer, since it's close to the observed increase in the loan value of 5.8% per year. Therefore, the rate of interest per annum is 5.7% to 1 d.p.

(b) Using the formula for compound interest, we can find the value of the loan 10 years after it starts:

A = P * (1 + r/n)^(n*t) = 2500 * (1 + 0.0574/1)^(1*10) = £4,745.60 (to the nearest 1p
