what is 320 million in scientific notation?

Answers

The scientific notation:  3.2 x10^2

The scientific notation of 320 million is 3.2 x [tex]10^8[/tex].

What is scientific notation?

It is the way of writing a large number between 1 to 10 with a power of 10.

Example:

2.9 x 10² is in scientific notation

3.4 x 10³ is in scientific notation

4.4 x 10³ is in scientific notation

We have,

320 million

This can be written as,

1 million = 1000000

So,

= 320 x [tex]10^6[/tex]

= 32 x [tex]10^7[/tex]

Multiply 10/10 to make a number between 1 and 10.

= 32/10 x 10 x [tex]10^7[/tex]

Make an exponent of base 10.

= 3.2 x [tex]10^8[/tex]

Thus,

The scientific notation of 320 million is 3.2 x [tex]10^8[/tex].

johnnys baseball team raised $1456 for next month's tournament. They need a total of $2,000 to play. the team has a total of 11 players. let x represent how much each player needs to raise in order to play in the tournament .

Answers

Given that Johney's baseball had raised $1,456 out of $2,000 they need to play the tournament.

Amount of money they still need to raise is given by $2,000 - $1,456 = $544.

Given that there is a total of 11 players in the team. Let x represent the total amount each player needs to raise, then x = $544 / 11 = $49.45

Therefore, each player needs to raise $49.45

What's an improper fraction is equal in mixed numbers 6 4/7

Answers

multiply the 7 (the denominator), and the 6 (the whole number). To this product, add the 4 (the numerator)
giving 46, to form the new numerator, and use the 7 as the new denominator.

So, 6 4/7 as an improper fraction is 46/7

The improper fraction equivalent to [tex]6\frac{4}{7}[/tex] is [tex]\frac{46}{7}[/tex].

An improper fraction is a fraction where the numerator is greater than the denominator.

A mixed fraction is defined as a fraction formed by combining a whole number and a fraction.

Since the given fraction is in mixed fraction so on solving it we get,

[tex]\dfrac{46}{7}[/tex].

Hence the required improper fraction will be [tex]\dfrac{46}{7}[/tex].

Answers

y=0.6x+12
y=0.6(2)+12
y=13.2

An equation in slope-intercept form models given situation is y=0.6x+20 and the length of the sunflower after two weeks is 21.2 meters.

Given that, a sunflower in Julia Rosario's garden was 12 centimetres tall when it was first planted. Since then, it has grown approximately 0.6 meters per day.

We need to write an equation in slope-intercept form that models this situation.

What is the slope-intercept form?

The slope-intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis). The equation of the line is the equation that is satisfied by each point that lies on that line.

The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as y = mx + b.

Let y be the length of a sunflower plant and the number of days be x.

Now, y=0.6x+20

The length of the sunflower after two weeks is y=0.6×2+20

⇒y=1.2+20=21.2 meters

Therefore, an equation in slope-intercept form models given situation is y=0.6x+20 and the length of the sunflower after two weeks is 21.2 meters.

Destiny read 1/4 of a book on the day she received it. The next day, she read 5/8 of the book. On the third day, she finished reading the book. What decimal represents the fraction of the book destiny read on the third day?

1/4 + 5/8 = 2/8 + 5/8 = 7/8...so she read 7/8 of the book on the first 2 days....that leaves 1/8 or (0.125) to read on the 3rd day to finish it.
This is a very easy question , 
first day = 1/4th of the book
2nd day=5/8th of the book
total = 1/4+5/8=2/8+5/8=(2+5)/8=7/8
Remaining book or the part of book she read on 3rd day is 1-(7/8)=(8-7)/8=1/8= 0.125 in decimal

A building is 2 ft from a 12 ft fence that surrounds the property. A worker wants to wash a window in the building 17 ft from the ground. He plans to place a ladder over the fence so it rests against the building. He decides he should place the ladder 8 ft from the fence for stability. To the nearest tenth of a foot, how long of a ladder will he need?

Answers

the ladder would have to be about 19.7 feet tall

Using Pythagoras theorem,  the ladder must be 19.7ft long.

What is Pythagoras theorem?

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.

Perpendicular = height of the window from the ground = 17ft

Base = distance of the foot of the ladder from the base of the building = 10ft

Hypotenuse = [tex]\sqrt{perpendicular^{2} +base^{2} }[/tex]

H = [tex]\sqrt{17^{2}+10^{2} }[/tex] = 19.4ft

Length of ladder  = 19.4ft
