Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?

Answers

Answer:

2 4/36

Step-by-step explanation:

To do this, multiply the whole number by the denominator and add it to the numerator.

8 x 9 = 72

72 + 4 = 76

76/9

Then multiply across (multiply numerators with numerators; denominators with denominators)

76 x 1 = 76

9 x 4 = 36

76/36 = 2  4/36

____________________________

A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.

1/4 x 8/1 = 8/4 = 2

1/4 x 4/9 = 4/36

 = 2  4/36

Answer:

2 1/9

Step-by-step explanation:

Multiplying fractions: Numerator times numerator over denominator times denominator. IF you have a mixed number, convert it into improper fraction, then do numerator times numerator over denominator times denominator.

1/4 x 76/9 (I got 76/9 because the 8 means 8 9/9s, so (8 x 9)=72 plus 4 because 4/9s=76/9)

1/4 x 76/9= 76/36

=38/18

=19/9

=2 1/9

what is the area of a semi circle when the diameter is 6

Answers

Answer: 14.13

Step-by-step explanation:

Your answer is 14.13

First, the formula for area of a semi circle is 3.14 x r^2 and divide by two.

To find the radius, we need to divide the diameter by two, which is 3.

So like

3.14 x 3^2/2

3.14 x 9/2

28.26/2

A=14.13

Answer:

14.13

Step-by-step explanation:

normal circle area equation = r^2*3.14

6/2=3

3*3*3.14

= 28.26

it's a semicircle so /2

=14.13

Label A
increasing,
decreasing,

Label B
increasing,
decreasing,
or no change

Label C
increasing,
decreasing,
or no change

Answers

Answer:

Label A - Increasing

Label B - No change

Label C - Decreasing

Step-by-step explanation:

Line A is going up so the speed is increasing.

Line B is just a straight line so there is no change.

Line C is going down so the speed is decreasing.

Answer:

Increasing no change decreasing

Step-by-step explanation:

Because when it is increasing it goes up and when it is not moving it is no change and when it goes down it would be decreasing.

Square root of x. Simplify the 4 of the root with the power of 2

Find The value of H:

S=2πr(r+h)

Answers

Answer:

[S / (2πr)] - r = h

Step-by-step explanation:

You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.

S = 2πr(r + h)

Divide by 2πr to try to isolate h

S / (2πr) = r + h

Subtract r from both sides to get h by itself

[S / (2πr)] - r = h

That is your final answer.

[tex]\\ \rm\Rrightarrow S=2\pir(r+h)[/tex]

[tex]\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}[/tex]

[tex]\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r[/tex]

[tex]\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}[/tex]

For number 7 since the rational number is countable, and the set of real numbers is uncountable, almost all real numbers are irrational. So you should choose false

Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10 2/3 pages? Complete the rate table to solve the proportion.

pages---> 4/3=32/3

Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2

Answers

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages
