nR is not a correct name for the line shown.

What is Line?

A line is a straight geometrical figure in one dimension. It is extended to both sides to infinity.

A line only has length and has no width, thus it is a one dimensional figure.

Given is a line where both sides extended to infinity.

The line is given a name n.

So we can denote the given line as n.

There are points marked on the line like R, S and T.

So we can denote the line also has the lines RT, ST and RS.

But we cannot denote the line with names like n R, n S and n T, all of which are incorrect notation.

Hence the incorrect notation for the given line is the second option n R.

60 out of 300 is what percent?

Answers


100%/x%=300/60(100/x)*x=(300/60)*x       - we multiply both sides of the equation by x100=5*x       - we divide both sides of the equation by (5) to get x100/5=x 20=x x=20
now we have: 60 is 20% of 300

Hope I helped!
~ Zoe

60 is 20% of 300.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

Let x% be a number such that

x% of 300 is 60

This forms an equation in one variable which can be solved by transposition.

[tex]x/100\times 300=60[/tex]

Simplifying it to calculate value of x.

On multiplying 100 both sides,

[tex]300x=6000[/tex]

On dividing 300 both sides,

x=20%

Thus, 20% of 300 is 60.

First, you have to do the formula:


A= 1/2(b1+ b2)×h

-----------------------------------------------------

Now plug in the numbers:

A=1/2(18+14)×12

----------------------------------------------------

Now solve:

A=1/2(18+14)×12

A=1/2(32)×12

A=16×12

A= 192in²

Finally, the answer is 192in²

Without calculating, explain how many decimal places are in the product 0.6 X0.4 X 1.9. Rewrite the expression as the product of two decimals to support your answer.

Answers

There's only one decimal point in the answer. This is quite obvious. Regardless of whether or not your adding, subtracting, dividing, or multiplying, there's really only going to be one decimal, ever. This doesn't change, However, what DOES change are decimal PLACES.

Looking at the problem, you see both .6 and .4 are placed to the right of the decimal, otherwise known as the tenths place (1/10). 

Looking at 1.9, you see you have one number (1) placed to the left of the decimal, the ones place, and another number placed to the right of the decimal (9), in the tenths place. 

Well, this is simple. You can look and see that your multiplying fractions against a whole number, which will of course make this whole number even smaller. By how much though??

Well, you can really tell this by looking at how MANY numbers are behind the decimal. You have .9, .4, and .6

That's 3 numbers behind the decimal place. This may not help you solve the problem itself, but this tells you here (ignoring the 1, that will be taken out immediately while solving and turned into a 0) that you will have 3 numbers placed from the tenths place all the way to the thousandths place.

Basically, this tells you that you'll have three decimal places to the right of the decimal. 

As for rewriting your problem to better show this, that's simple too.

All you have to do is simple multiplication, just in the tenths place. How? You know that 6*4 (referring to .6 and .4) is 24, that means that .6*.4 will be .24

How does this support your answer before? .24 has TWO numbers to the right of the decimal. That's TWO decimal places. With the .9 in 1.9, that's still THREE decimal places to the right of the decimal, and your answer would be the same.

So, here's it re-written.
1.9*.24=X

~Hope this helps!


Final answer:

The product 0.6 x 0.4 x 1.9 has three decimal places.

Explanation:

To determine the number of decimal places in the product 0.6 x 0.4 x  1.9, we can rewrite each decimal as the product of two decimals and count the total number of decimal places.

0.6 can be written as 0.6 x 1.0, which has one decimal place.

0.4 can be written as 0.4 x 1.0, which also has one decimal place.

1.9 can be written as 1.9 x 1.0, which has one decimal place.

Since each decimal has one decimal place, the product 0.6 x 0.4 x 1.9 has a total of three decimal places.

Pe ling needs 2 yard of fabric for a craft project. She has 3 feet already. How many inches of fabric does she still need ?

Answers

First, you want them to be the same units. 
We'll convert yards to feet.

Since there are 3 feet in a yard 

2 yards * 3 = 6 feet

So she needs 6 yards and has 3 feet.

6-3=3     3 feet is needed

So to make things easier convert 3 feet to inches
12 in. in a foot

12*3 feet= 36 inches
She needs 36 inches of fabric
She needs 2 yards. 

2 yards = 6 feet

3 feet = 36 inches

So, she has half of it done already.
If 2 yard = 6ft, then 1 yard = 3ft.
In 1 foot, there is 12in.

Therefore, she still needs 36 inches of fabric.

Carter has 60 balloons. 4/12 of the balloons are black, and 3/12 of the balloons are white. The rest of the balloons are red. Which series of calculations shows how many red balloons Carter has?

Answers

Let

B------------> black balloons
W-----------> white balloons
R-----------> red balloons

Step 1
calculate the amount of black  balloons and white balloons
the total of balloons is 60
B=(4/12)*60=20 balloons
W=(3/12)*60=15 balloons

Step 2
calculate the amount of red balloons
R=60-[B+W]---------> R=60-[20+15]
R=60-(35)=25 balloons

the answer is 25 red balloons


Final answer:

To find the number of red balloons Carter has, subtract the number of black and white balloons from the total number, using fractions to represent the proportion of black and white balloons. Multiply the total number of balloons by the fraction representing red balloons to find the number of red balloons.

Explanation:

To find the number of red balloons Carter has, we need to subtract the number of black and white balloons from the total number of balloons. Since 4/12 are black and 3/12 are white, we can add these fractions together to find the total fraction of balloons that are either black or white: 4/12 + 3/12 = 7/12.

To find the fraction of balloons that are red, we can subtract the fraction of black and white balloons from 1 (since the sum of all fractions should equal 1): 1 - 7/12 = 5/12.

To find the actual number of red balloons, we can multiply the total number of balloons (60) by the fraction of red balloons: 60 x 5/12 = 25 red balloons.

(-9, -6);
-9 - 3(-6) = 9
-9 + 18 = 9

Final answer:

To convert 1/5 mile to other forms, it can be represented as 2/10 when the denominator is 10, 20/100 when the denominator is 100, and 0.2 as a decimal.

Explanation:

To convert 1/5 mile into a fraction with 10 in the denominator, multiply both the numerator and the denominator by 2 to get 2/10. To get a fraction with 100 in the denominator, multiply both the numerator and the denominator of 1/5 by 20 to get 20/100. As a decimal, 1/5 is equivalent to 0.2 because 1 divided by 5 equals 0.2.

If a population of 100 cells triples every hour, which function represents p(t), the population after t hours?

Answers

Exponential functions are in the form [tex]f(x)=a*b^x[/tex], where a is the initial value, b is the growth rate (percent increase) + 1, and x is the number of time periods.  Our initial value is 100, and we're given the growth rate + 1 (tripling is the same as increasing by 200%; 200%=2.0; 2.0+1=3).  Therefore our function is [tex]p(t)=100*3^t[/tex].

Final answer:

The function that describes a cell population of 100 cells tripling every hour is stated by the formula p(t) = 100(3)^t, which represents exponential growth.

Explanation:

This problem describes a phenomenon where the initial population experiences exponential growth in a way that it triples every hour. Exponential growth is typically represented by the function p(t) = p⁰×r^t, where:

- p(t) represents the final amount of entities (in this case, population) after time t,
- p0 is the initial amount of entities (in this case, initial population),
- r is the growth factor,
- and t is time.

In these types of problems, the base number of the exponent (in this case 3) represents the growth factor. This is based on the fact that every time period (in this case, every hour), the population triples, or in other words, gets multiplied by 3.

The initial population given is 100 cells. This is represented by p0 in our formula and is also the coefficient in our function.

By considering both the initial population and the rate at which it triples, we can construct the function as p(t) = 100 × 3^t.

Therefore, according to our built function, the correct choice is b. p(t) = 100 × 3^t.
