unitary method examples.

Answers

Answer 1

Answer:

For example, if a car runs 44 km on 2 litres of petrol then we can use the unitary method to find out the kilometres it will cover on 1 litre of petrol. In other words, the method by which we find out the value of one unit and further use it to find the value of multiple units is known as the unitary method.

A go cart designer wants to build a Go Cart that measures 4 feet in height, 6 feet in width and 8 feet in length. He needs to construct a three - dimensional model of the Go Cart. Which measurements are appropriate for the scale model? a. 2 feet wide, 5 feet long and 2 feet high b. 3 feet wide, 4 feet long and 2 feet high c. 2.5 feet wide, 2 feet long, and 1.5 feet high d. 6 feet wide, 5 feet long and 3 feet high

Answers

Answer:

The correct answer is:

3 feet wide, 4 feet long, and 2 feet high (b)

Step-by-step explanation:

The appropriate scale for the model must be equivalent to the scale of the actual design. This means that the variation must be of the same magnitude in the length, height, and width.

Cart design = 4 feet high; 6 feet wide; 8 feet long

Cart design = 4H : 6W : 8L

where H, W, and L are height, width, and length respectively.

since the model of the Go Cart will be lesser than the actual Cart, let us divide the original cart design by the model designs given in the option, anyone that gives us a consistent variation is a right scale. This is done as follows:

a) Model design = 2H : 2W : 5L

dividing the original dimension by the model:

[tex]\frac{4H}{2H} : \frac{6W}{2W} : \frac{8L}{5L} \\= 2 : 3 : 1.6\\[/tex]

since the variations are not the same, this is the wrong model.

b) Model design = 2H : 3W : 4L

[tex]\frac{4H}{2H} : \frac{6W}{3W} : \frac{8L}{4L} \\= 2 : 2 : 2\\[/tex]

variation is the same across the three dimensions, hence this is the right model.

You can go ahead to use the same principle to do the third model, to see what you will get.

Complete the solution of the equation. Find the value of Y when X equals 5. X-5y=45

Prove that quadrilateral Q(1, 2), U(2, 5), A(5, 7) and D(4, 4) is a parallelogram by using slopes.

Slope of QU =

Slope of AD =

Slope of UA =

Slope of QD =

Which sides are parallel (give the letters) A) sides QU and AD B) sides QU and UA C) sides UA and QD D) sides AD and QD

Answers

Answer:

[tex]m = 3[/tex] ---- Slopes of QU and AD

[tex]m =\frac{2}{3}[/tex] ---- Slopes of UA and QD

Sides QU and AD have the same slope

Sides UA and QD have the same slope

Step-by-step explanation:

Given

[tex]Q = (1, 2)[/tex]

[tex]U = (2, 5)[/tex]

[tex]A = (5, 7)[/tex]

[tex]D = (4, 4)[/tex]

Solving (a): Slope of QU

[tex]Q = (x_1,y_1)= (1, 2)[/tex]

[tex]U = (x_2,y_2)= (2, 5)[/tex]

Slope, m is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{5-2}{2-1}[/tex]

[tex]m =\frac{3}{1}[/tex]

[tex]m = 3[/tex]

Slope of AD

[tex]A =(x_1,y_1) = (5, 7)[/tex]

[tex]D = (x_2,y_2) = (4, 4)[/tex]

Slope, m is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{4-7}{4-5}[/tex]

[tex]m =\frac{-3}{-1}[/tex]

[tex]m = 3[/tex]

Slope of UA

[tex]A =(x_1,y_1) = (5, 7)[/tex]

[tex]U = (x_2,y_2)= (2, 5)[/tex]

Slope, m is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{5-7}{2-5}[/tex]

[tex]m =\frac{-2}{-3}[/tex]

[tex]m =\frac{2}{3}[/tex]

Slope of QD

[tex]Q = (x_1,y_1)= (1, 2)[/tex]

[tex]D = (x_2,y_2) = (4, 4)[/tex]

Slope, m is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{4-2}{4-1}[/tex]

[tex]m =\frac{2}{3}[/tex]

Solving (b): Parallel Sides

Two sides are said to be parallel if they have the same slope.

The slope were calculated in (a) above and from there, we have the following observations

1. QU and AD have the same slope of 3

2. UA and QD have the same slope of 2/3

Alba worked for 6 hr and 45 min at $10.90 per hour. What numbers could she use to estimate how much money she earned? Estimate the amount she earned and state whether you think the exact amount is a little more or a little less than your estimate

Answers

Answer:

Step-by-step explanation:

If we're going by estimation, then you can do 11 and 7 hours, meaning that she would make 77 for the 7 hours but the exact answer would be a bit less than the estimation

10.9 times 6.75 is 73.58 roughly. so 3 dollars and 42 cents off

Answer:

1. She could use 7 hours and 11 dollars per hour.

2. $77 (7x11)

3 I'd say my estimate is a little more than the exact amount because I did 6.75 (6.75 because 45 minutes is 75% of a hour) x 10.90 and got 73.575.

Lynn bought 3 bags of chips for $1.86 each and 2 bottles of apple juice for $3.27 cach. If the tax on the items was $0.43, what was the total amount she spent?

Answers

Answer:

for the chips she spent $5.15 and for the apple juice she spent $6.11

Step-by-step explanation:

1.86*3=5.58

5.58-0.43=5.15

3.27*2=6.54

6.54-0.43=6.11

12.98 because 1.86 times 3 is 5.58 plus 3.27 times 2 is 6.54 plus 0.43 times 2 is 0.86 and Adding 0.86+5.58+6.54=12.98

What is the distance between these two points?

Answers

The points (-6,8) and (0,8) are coordinate points, and the distance between the points (-6,8) and (0,8) is 6 units

The distance between the two points

The points are given as:

A = (-6,8)

B = (0,8)

The distance between the points is calculated using:

[tex]d= \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]d= \sqrt{(-6 - 0)^2 + (8 -8)^2}[/tex]

Evaluate

d = 6

Hence, the distance between the points (-6,8) and (0,8) is 6 units

Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.

How to calculate the interest rate?

To calculate the new interest rate after purchasing points, we need to know the cost of one point and the number of points purchased.

One point typically costs 1% of the mortgage amount, so three points would cost 3% of the mortgage amount. The cost of the points is usually paid upfront at closing.

Assuming Neil's mortgage amount is $100,000, the cost of 3 points would be:

3% x $100,000 = $3,000

To calculate the new interest rate, we need to add the cost of the points to the original interest rate and then recalculate it as a percentage:

New rate = Original rate + (Cost of points / Mortgage amount)

New rate = 4.95% + ($3,000 / $100,000)

New rate = 4.95% + 3%

New rate = 7.95%

So, Neil's new interest rate after purchasing 3 points would be 7. 95%. The closest option is B. 4.575%.
