Justin rides his bicycle 2.5 kilometers to school.
Luke walks 1,950 meters to school. How much
farther does Justin ride to school than Luke
walks to school?

Answers

Answer 1

Answer:

1 kilometre = 1000 metres
2.5km = 2.5 × 1000m = 2500m
2500 - 1950 = 550m

Therefore Justin rides 550m farther than Luke walks to school.

Find the center and radius of the circle with this equation:
x² + 16x + 64 + y² - 2y + 1 = 144

Answers

By completing squares, we will see that the radius is 12 units and the center is (-8, 1).

How to find the center and radius of the circle?

The circle of center (x₁, y₁) and radius r is written as:

(x - x₁)² + (y - y₁)² = r²

Now we go to our equation:

x² + 16x + 64 + y² - 2y + 1 = 144

Now we need to complete squares:

(a + b)² = a² + 2ab + b²

Then we can rewrite:

(x² + 2*8*x + 8*8) + (y² - 2y + 1) = 12²

(x + 8)² + (y - 1)² = 12²

So the center is the point (-8, 1) and the radius is 12 units.

Alex's favorite number is 175% of Winnie's favorite number. Winnie's favorite number is 48 less than Alex's favorite number. What is Winnie's favorite number?

Answers

Answer:

64

Step-by-step explanation:

The information can be written as:

Let Alex's number = x

Winnie's number = y

x = 1.75y

x = y + 48

Substitute 1.75y for x:

1.75y = y +48

0.75 y = 48

3/4 y = 48

y = 64

Winnie's favourite number = 64.

Nick walked 5 miles to reach his aunt's house. from there he traveled 8 miles to the shopping mall on a bicycle. he traveled 80% faster on the bicycle than on foot. let r represent his rate of walking in miles per hour. identify the expression that represents the number of hours nick took to reach the shopping mall in terms of r. then find the time taken by nick to reach the shopping mall if he walked at an average speed of 3 miles per hour.

Answers

The expression of time in terms of r is T = 85/9r. If he walked at an average speed of 3 miles per hour. Then the time taken by nick to reach the shopping mall will be 3 hours and 60 minutes.

What is speed?

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

Nick walked 5 miles to reach his aunt's house.

From there he traveled 8 miles to the shopping mall on a bicycle.

He traveled 80% faster on the bicycle than on foot.

Let r represent his rate of walking in miles per hour. Then the 1.8r will be the rate of cycling in miles per hour.

Then the number of hours nick took to reach the shopping mall in terms of r will be

T = t₁ + t₂

Where t₁ is the time taken to reach his aunt's house and t₂ is the time taken to reach the shopping mall from his aunt's house. Then we have

T = 5 / r + 8 / 1.8r

T = 1/r (5 + 8/1.8)

T = 85/9r

If r is 3 miles per hour, then the time taken by nick to reach the shopping mall will be

T = 85 / (9 x 3)

T = 3.15 hours

T = 3 hours and 9 minutes

Three solid shapes a, b and c are similar.

the volume of shape b is 64 cm
the ratio of the surface area of shape b to the surface area of shape c is 8:15
work out the ratio of the height of shape a to the height of shape c.

Answers

The ratio of the height of shape A to the height of shape C is [tex]\frac{3}{10}[/tex]

Calculations and Parameters:First step:

Recall that similar figures have the same scale factor squared due to the ratio of its surface area.

Hence,

We would make:

z-----> the scale factorx----> surface area shape Ay----> surface area shape B

[tex]z^2 = x/y\\z= 2/5[/tex]

Therefore, the ratio of the height of shape A to the height of shape B is = [tex]\frac{hA}{hB} = \frac{2}{5}[/tex]

Next step:

To find the ratio of the height of shape B to the height of shape C, we would perform a similar operation which is:

[tex]z^3 = 27/64\\z= 3/4[/tex]

The ratio is:

[tex]\frac{hB}{hC} = \frac{3}{4}[/tex]

Final step:

To find the ratio of the height of shape A to the height of shape C would be:

[tex](\frac{hA}{hB}) (\frac{hB}{hC} )= \frac{hA}{hC}[/tex]

$75 before tax. Disc: 10% Tax: 7%, Tip: 20% what’s the total?

Answers

Answer:

$102.75

Step-by-step explanation:

Given the following question:

We are given a cost of 75 dollars and are being asked to find the total cost after adding a tip, tax, and disc to the cost. To find this answer we will use the formula to calculate percentages making sure we use 75 as our base for each addition to our total cost.

Formula to calculate percentages:

[tex]\frac{p\times n}{100}[/tex]

First the disc:

[tex]\frac{10\times 75}{100}[/tex]
[tex]10\times75=750[/tex]
[tex]750\div100=7.5[/tex]
[tex]=7.5[/tex]

Next the tax:

[tex]\frac{7\times75}{100}[/tex]
[tex]7\times75=525[/tex]
[tex]525\div100=5.25[/tex]
[tex]=5.25[/tex]

Last but not least the tip:

[tex]\frac{20\times75}{100}[/tex]
[tex]20\times75=1500[/tex]
[tex]1500\div100=15[/tex]
[tex]=15[/tex]

Finally add:

[tex]75+7.50+5.25+15=102.75[/tex]
[tex]=102.75[/tex]

The total cost after adding the disc, tax, and the tip will be "$102.75."

The simple interest in which Casho invests money was 8%.

What is simple interest?

Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.

We know simple interest (SI) is given by SI = (p×r×t)/100, where

p = principle, r = rate in percentage, and t = time in years.

Given, p = 30, SI = (32.40 - 30) = $2.40 and t = 1.

Therefore, 2.40 = (30×r×1)/100.

240 = 30r.

r = 240/30.

r = 24/3.

r = 8.

How to determine the exponential equation?

On the graph, we have the following points

An exponential function is represented as;

y = ab^x

So, we have:

ab^1 = 2 and ab^4 = 4

Divide both equations

b^3 = 2

Take the cube root of both sides

b = 1.26

Substitute b = 1.26 in ab^1 = 2

1.26a = 2

Divide both sides by 1.26

a = 1.59

So, we have:

y = ab^x

y = 1.59 * 1.26^x
