If a:b = 2:5 and b:c = 3:4, find (i) a:c (II) a:b:c

Answers

Answer 1

Answer:

(i) 3:10

(ii) 6:15:20

Step-by-step explanation:

a : b

2 : 5

b : c

3 : 4

Since both values of b in the two ratios are different, we need to multiply each ratio so that they are the same. I will multiply the first ratio by 3 and the second ratio by 5 so that b = 15 units.

a : b

6 : 15

b : c

15 : 20

Now that both values of b are the same, we can arrange the variables a, b and c together.

Thus:

a : b : c

6 : 15 : 20

a : c

6 : 20

3 : 10

Answers

Answer: [tex]2\dfrac13\ h[/tex]

Step-by-step explanation:

Given: Speed = [tex]10\dfrac15[/tex] mi/h  [tex]=\dfrac{21}{5}[/tex]mi/h  

Distance need to be travel = [tex]1\dfrac45[/tex] miles [tex]=\dfrac{9}{5}[/tex] miles

[tex]speed=\dfrac{distance}{time}\\\\\Rightarrow\ time=\dfrac{distance}{speed}[/tex]

[tex]\Rightarrow\ time =\dfrac{\dfrac{21}{5}}{\dfrac{9}{5}}\\\\\Rightarrow\ time =\dfrac{21}{9}\\\\\Rightarrow\ time =\dfrac{7}{3}\\\\\Rightarrow\ time =2\dfrac13\ h[/tex]

Hence, time taken to travel = [tex]2\dfrac13\ h[/tex]

What is the area of the semicircle

Answers

Answer:

Apply the formula πr^2/2

Answer:

56.52

Step-by-step explanation:

The forst thing to do is find the area of the entire circle.

[tex] {r}^{2} \times 3.14[/tex]

So add the radius to the equation.

[tex] {6}^{2} \times 3.14[/tex]

Solve for the equation.

[tex]36 \times 3.14 \\ 113.04[/tex]

Now that is the area of the entire circle, so all is needed is to divide that by 2.

[tex]113.04 \div 2 \\ 56.52[/tex]

Now you have the area of the semicircle.

What is correlation?"It describes the degree to which two variables move in coordination with one another. ""If the two variables move in the same direction, then those variables have a positive correlation." "If they move in opposite directions, then they have a negative correlation."What is scatterplot?

"It is a graph of the paired (x, y) sample data with a x-axis and y-axis."

What is linear association?"It is used to describe a straight-line relationship between two variables.""It can be expressed as mathematical equation of the form y = mx + b.""In this type of association, when one variable changes it also causes the changes in the second variable.""The strongest linear association occurs when the slope is 1 that is m = 1"

We know that, correlation is defined as the statistical association between two variables.

A correlation exists between two variables when one of them is related to the other in some way.

A relationship or association between two variables is linear when the points on a scatterplot follow a somewhat straight line pattern.

A line that goes roughly through the middle of all the scatter points on a graph is the line of best fit.

The closer the points are to the line of best fit the stronger the linear association is.

This means, a line can be drawn through the data points which approximates the data.

Therefore, the statement that describes a linear association is - A line can be drawn through the data points which approximates the data

-[tex]\frac{19}{20}[/tex]y = 380

The coordinates of point P are (1, -1)

Step-by-step explanation:

If the point (x, y) reflected about the x-axis, then its image is (x, -y)To find the image of a point reflected about the x-axis change the sign of its y-coordinateThe rule is R x-axis → (x, -y)

If the point (x, y) reflected about the y-axis, then its image is (-x, y)To find the image of a point reflected about the y-axis change the sign of its x-coordinateThe rule is R y-axis → (-x, y)

→ Assume that the coordinates of point P are (x, y)

∵ The coordinates of point P are (x, y)

∵ The rule of the reflection is R y-axis (P)

∴ Its image = (-x, y)

∵ The image = (-1, -1)

→ Equate the two images

(-x, y) = (-1, -1)

∴ -x = -1

→ Divide both sides by -1

x = 1

y = -1

The coordinates of point P are (1, -1)

Two bottle rockets are simultaneously launched on parallel paths, from 5 feet apart on level ground. After 0.1 second, the rockets are at the same height.

Which theorem or definition can you use to show that the rockets are still 5 feet apart 0.1 second after launch?

Help asap please it's due today :)

Answers

Answer:

The definition of parallel lines are lines that have a constant minimum distance between them at any given point along the lines, such that the lines are the same distance apart all through

Therefore, given that we have;

1) The path of the two bottle rockets are parallel,

2) The initial distance between the two rocket on level ground = 5 feet = The perpendicular (shortest) distance between the two rockets

3) The shortest distance between the rockets having the same height moving on parallel path will be constant = 5 feet

4) The height of the two rockets after 0.1 second = Constant = 5 feet

5) Therefore, by the definition of parallel lines, distance between the two rockets which are at the same height after 0.1 second will still be 5 feet

Find the area of a circle with a circumference of \blueD{18.84}18.84start color #11accd, 18, point, 84, end color #11accd units.

Answers

Answer:

28.26 u²

Step-by-step explanation:

What we know:

A circle has a circumference of 18.84 u.

That means the diameter is 6, and the radius is 3.

The area of a circle can be found with: πr²

3.14(3²)

3.14(9)

28.26 u²

The area of the circle is 28.26 square units when the circumference of circle is 18.84 units.

What is Circle?

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The circumference of the circle is 18.84 units

We have to find the area of circle

To find area we need to know the radius

Circumference of circle = 2πr

18.84 = 2πr

18.84 = 2×3.14 r

18.84=6.28 r

Divide both sides by 6.28

r=18.84/6.28

r=3

Now let us find area

Area = πr²

=3.14×3²

=9×3.14

=28.26 square units

Hence, the area of the circle is 28.26 square units when the circumference of circle is 18.84 units.

Give your answer to the nearest penny

Need this ASAP thanks

Answers

Answer:

The original price of the holiday was $ 681.81.

Step-by-step explanation:

As the price of the holiday was reduced by 12% to a value of $ 600, it can be said that this price is 88% of its original price (100 - 12). Therefore, to determine the original price of the holiday, it is necessary to perform the following calculation:

88 = 600

100 = X

(100 x 600) / 88 = X

60,000 / 88 = X

681.81 = X

Therefore, the original price of the holiday was $ 681.81.

Tuition for one year at a state university is about $13,000. Devon would like to attend this university and will save money each month for the next 4 years. His parents will give him $5,200 for his first year of tuition. Which plan shows the minimum amount of money Devon must save to have enough money to pay for his first year of tuition?

Answers

Answer:

$162.50 per month for the next 4 years

Step-by-step explanation:

Here are the options to this question :

Save $270.83 per month for the next 4 years

Save $162.50 per month for the next 4 years

Save $650.00 per month for the next 4 years

Save $108.33 per month for the next 4 years

If Devon's parents would give him $5,200 for his first year of tuition, Devon needs to save a minimum of :

$13,000 - $5,200 = $7,800

If he saves per month for the next four months, he would save 48 times ( 12 months in a year multiplied by 4 years)

The minimum he should save per month = $7800 / 48 = $162.50
