Answer 1

Question:

Alex skateboards at a constant speed from his house to school 3.8 miles away. It takes him 18 minutes.

a. What fraction represents his constant speed, c?

b. After school, Alex skateboards at the same constant speed to his friend’s house. It takes him 10 minutes.  Write the fraction that represents constant speed, c, if he travels a distance of y.

c. Write the fractions from parts(a) and (b) as a proportion, and solve to find out how many miles Alex’s  friend’s house is from school. Round your answer to the tenths place.

Answer:

(a) [tex]c = \frac{3.8}{18}[/tex]

(b) [tex]c = \frac{y}{10}[/tex]

(c) 2.1 miles

Step-by-step explanation:

Solving (a):

Given

[tex]Distance = 3.8\ miles[/tex]

[tex]Time = 18\ minutes[/tex]

Required

Determine the constant speed, c.

Speed is calculated as:

[tex]Speed = \frac{Distance}{Time}[/tex]

So, we have:

[tex]c = \frac{3.8}{18}[/tex]

Solving (b):

Given

[tex]Distance = y[/tex]

[tex]Time = 10\ minutes[/tex]

Required

Determine the constant speed, c.

Speed is calculated as:

[tex]Speed = \frac{Distance}{Time}[/tex]

So, we have:

[tex]c = \frac{y}{10}[/tex]

Solving (c): Write (a) and (b) as proportions and solve for y.

As a proportion, we have

[tex]\frac{y}{10} = \frac{3.8}{18}[/tex]

Multiply both sides by 10

[tex]10 * \frac{y}{10} = 10 * \frac{3.8}{18}[/tex]

[tex]y = 10 * \frac{3.8}{18}[/tex]

[tex]y = \frac{38}{18}[/tex]

[tex]y = 2.11111[/tex]

[tex]y = 2.1\ miles[/tex]  ---- approximated

What is the volume of this figure? Round to the nearest hundredth.

Answers

Answer:

I believe the volume is 80 cubic centimeters.

Step-by-step explanation:

V = volume

B = base

H = height

V = BH

V = (4) 20

V = 80

Volume =Area of the base times height

Since your base is a circle, you use A=pi x radius squared to get the area of the base.

I’m using 3.14 for pi.

A of base= (3.14)(2)(2)= 12.56

Now multiply 12.56 by height (20)

Volume is 251.2 cm cubed.

Select from the drop-down menus to correctly complete each statement An arithmetic sequence represents a _____ function because it has a constant rate of change.

1st line :linear or nonlinear
2nd line:linear or nonlinear
3rd line: 1 , 4 or different amounts
4th line:represents or does not represent



Answers

Answer:

1st line: linear

2nd line: linear

3rd line: 4

4th line: represents

Step-by-step explanation:

Arithmetic sequences increase by the same number each time. This means they are linear, as linear functions also increase by the same number each time.

So, the first and second lines have the answer of linear.

In the arithmetic sequence given, 4 is added to the previous number as it progresses. This represents a function.

So, the third line has the answer of 4, and the fourth line has the answer or represents.

Using arithmetic sequence concepts, it is found that the lines are:

1st: linear.2nd: linear.3rd: 4.4th: represents

What is an arithmetic sequence?

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of the sequence is given by:

[tex]a_{n+1} = a_1 + (n-1)d[/tex]

Hence, an arithmetic sequence is also a linear function with rate of change d.

In this problem:

The sequence is: 9, 13, 17, 21.The rate of change is of 4, as when n increases by 1, each value increases by 4.

Hence, the lines are completed by:

1st: linear.2nd: linear.3rd: 4.4th: represents

Find the area of the shape below.
11 cm
14 cm
9 cm
20 cm

Answers

Answer: A = 235 cm²

Step-by-step explanation: The figure has not a regular shape, but we can divide it to other figures that are easier to calculate the area.

For example, we can divide this figure in 2:

1) A square of side 9;

2) A rectangle of sides 14 and 11;

The image below represents what it is described.

Area of quadrilateral is calculated as A = length x width

Since both rectangle and square are quadrilateral, area of each will be

[tex]A_{square}[/tex] = 9.9

[tex]A_{square}[/tex] = 81

[tex]A_{rectangle}[/tex] = 11.14

[tex]A_{rectangle}[/tex] = 154

The area of the shape is the sum of each part we calculated:

[tex]A_{total}[/tex] = 154 + 81

[tex]A_{total}[/tex] = 235

The area of the shape is 235 cm².

I'm not quite sure how to solve this problem. Note I do understand the problem if it was like this 7π/4 because you would do 7/4 times 180 which would be 315. But now since there is not an number in from of π/-12 i'm confused.

Bill sees two boxes of baseball cards at a card show. The first box has 150 cards for $12.55.The second box has 120 cards for $9.60. The cards in which box are cheaper?

Answers

Answer: Cards in second box are cheaper.

Step-by-step explanation:

We are told that the first box has 150 cards for $12.55. Therefore, the cost of one card would be:

= $12.55 / 150

= $0.084.

The second box has 120 cards for $9.60. Therefore, the cost if one card would be:

= $9.60 / 120

= $0.08

Therefore, the cards in the second box are cheaper.
