Answer: The 8 in the hundredths place represents 1/10 of the 8 to its lefts response

Step-by-step explanation:

Answer:

It is increased by 100%. The numerator is two times more than the denominator. That's why original fraction will become [tex]\frac{2x}{y}[/tex].        

Step-by-step explanation:

We need to find the percentage, if its numerator is increases by 60% and its denominator decreases by 20%.

First, we let the original fraction: [tex]\frac{x}{y}[/tex]

We have given its numerator is increases by 60% and denominator is decreases by 20% then,

New fraction will become = [tex]\frac{1.6x}{0.8y}[/tex].

Divide the new fraction by original fraction, then we get:

[tex]\frac{1.6x}{0.8y}[/tex]/ [tex]\frac{x}{y}[/tex]

[tex]\frac{1.6x}{0.8y}[/tex]* [tex]\frac{x}{y}[/tex]

Then, it will become [tex]\frac{1.6}{0.8}[/tex].

We can see that, The numerator is two times more than the denominator. That's why original fraction will become [tex]\frac{2x}{y}[/tex].

It is increased by 100%.

If we take an example, Suppose the original fraction is [tex]\frac{5}{8}[/tex] and the new fraction will become [tex]\frac{1.6*5}{0.8*8}[/tex].

= [tex]\frac{8}{6.4}[/tex] = [tex]\frac{80}{64}[/tex]

= [tex]\frac{10}{8}[/tex], it is twice of original fraction [tex]\frac{5}{8}[/tex].

At 2 pm, the angle between the hour hand and the minute hand of a clock is 20 degrees. The calculation takes into consideration that the hour hand advances as minutes pass within an hour.

The angle between the hour and the minute hand at 2 pm can be calculated in the following way. First, remember that a full circle, representing one hour on a clock, equals 360 degrees. So, each hour equals 30 degrees (360 divided by 12 hours). However, the hour hand also moves as the minutes pass. At 2 pm exactly, the minute hand is on 12, while the hour hand is at 2. But, the hour hand has also moved 1/3 of the way between 2 and 3 (since 20 minutes have passed in the hour). It is closer to 3 by 1/3 of 30 degrees which equals 10 degrees. Hence, the hour hand is at a position of 60 degrees (2 hours times 30 degrees per hour). Therefore, the angle between the two hands at 2 pm is 20 degrees.

Multiplying 6 and 8 gives the value of 48. The question seems to mention '5s fact', which typically refers to multiplication facts of 5, but this does not directly relate to multiplying 6 and 8.

It seems that the '5s fact' mentioned in the question doesn't directly apply to the multiplication problem provided (6x8). Rather, in the context of simple multiplication, a 'fact' typically refers to a multiplication fact, which is a statement of an equation that can be considered universally true in arithmetic. For instance, 5x1=5 or 3x2=6 are multiplication facts.

To multiply 6 and 8, regardless of any number's multiplication facts, you would simply calculate 6x8, which equals 48.

With regard to the '5s fact', if we are referring to the multiplication facts of 5, these would include equations like 5x1=5, 5x2=10, and so on. However, none of the '5s facts' directly relate to multiplying 6x8. If the question refers to some other concept that has not been clarified, please provide further details.

Answer:

The answer is b. 8 1/4 feet.

Answer:

since u don't need the answers imma just leave this here, thnx for the points :)

Step-by-step explanation:

So we are given the fraction ratio...

7 girls

---------

5 boys

if we make the fraction

21 girls

----------

x boys

equal each other, we can cross multiply and find x.

Cross multiplying means to multiply 7 times x and 21 by 5.

then we set up a little equation

7x = (21)(5) First lets solve what 21 times 5 is 

7x = 105 Now we have to divide both sides by 7 to get x alone.

÷7 = ÷7  On the left side of the equation the 7 cancels and we solve on the right.

x = 15

So we know that when we have 21 girls in the 7th grade classroom we also have 15 boys.

Good Luck! :)

Answer: A. F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5).

Answer:

51.3

Step-by-step explanation:

In order to calculate this, you have to remember the norms for the solution of math problems with hierarchy of operations called PEMDAS:

   Parentheses (simplify inside 'em)

   Exponents

   Multiplication and Division (from left to right)

   Addition and Subtraction (from left to right)

So we first solve parentheses:

11[(9^2-5^2)= 11(81-25)=11(56)= 616.

and now we have to divide that by the result of:

2^2+8

Remember first exponents:

2^2+8= 4+8=12

ANd now we just divide:

616/12=51.3333

So the answer would be 51.3

Answer:

true

Step-by-step explanation:

39.538 divided by 5.3 using standard method. Which is true

The fraction is, 12/36 is the fraction 12 over 36.

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

here, we have,

the fraction 12 over 36

Is quite simple first find out what can go into 12 and 36

The factors that can go into 12 and 36 is 12.

12÷12=1

36÷12=3

So the final answer will be 1/3.
