The ratio of boys to girls in a venior Senior Promede is 4:3 Jane counted that- there are 12 more boys than girls. How many boys and girls, how many are there
in the prom?​

Answers

Answer 1
Answer:

Answer:

36 girls, 48 boys . Total of 84 in the prom.

Step-by-step explanation:

Let the number of girls be x, then the number of boys is x+12.

So we have the equation:

4/3 = (x + 12) / x

4x = 3x + 36

x = 36.

So there are 36 girls and 48 boys in the prom.

Answer:

a) YES. Repeating decimal

b) YES. Repeating decimal

c) NO. Decimal neither terminates nor repeats

d) YES. Terminating decimal

Step-by-step explanation:

Any rational number can be written as a fraction, that is, a division of integers.

a) The number \overline{0.54} has a repetitive period of 54. It can be expressed as a fraction because its decimal are repeating forever

b) The number 0.16666... (expressed as a repeating 6) can also be converted to a fraction because it's a repeating decimal

c) The number 0.5473... cannot be expressed as a fraction because the ellipsis (...) means the decimals continue with no limit and no pattern can be found (no repetitive decimal)

d) The number 0.378 can be easily expressed as a fraction because it has a finite number of decimals (no ellipsis) or a terminating decimal

1.Find the exact solution to the equation.(2 points)

log base four of x equals two.

Answers

Answer:

x = 16

Step-by-step explanation:

The equation is \log_(4) x = 2

Now, converting this logarithmic equation into exponential equation, we get

x = 4^(2) = 16(Answer)

Alternate solution:

Given,\log_(4) x = 2

\log_(4)x = 2\log_(4)4

{Since, we know that \log_(a)a = 1}

\log_(4)x = \log_(4)4^(2) = \log_(4)16

{Since, a\log b = \log b^(a) is a property of logarithm}

Cancelling log from both sides we get,

⇒ x = 16 (Answer)

Answer:

x = 8^4

Step-by-step explanation:

hey there,

< Here is what is given:

_(8) x=4

There's actually a lot of different ways you can remember this but the way I remember this is x is equal to 2nd to the power of last.

So 8 is the 2nd (since log is first), 4 is last (very last thing in the equation).

x = 8^4

You can use any of your own ways to remember this, but this is just my personal way. :) >

What is 3/8 divided by 9/16? Please explain and show work.

Answers

To divide a fraction by a fraction you multiply by the reciprocal. That means that you turn the second fraction upside-down, and multiply.
So if you have 3/8 divided by 9/16, you will end up with
3/8 * 16/9
So now you can simplify diagonally, and it becomes 1/1 * 2/3, which is the same as 1 * 2/3.  The next step would be just to multiply fractions like normal, but since we know that any number times 1 is the number, the answer is 2/3
ANSWER: 2/3
Hope this helped, and feel free to ask more questions if you need!!(:
step1:keep
        that mean you keep 3/8 normal
step2:change
         that mean you change ÷ to ×
         3/8×
step3:flip
         that mean you flip the second number
         9/16 change to 16/9
         3/8×16/9=48/72
so the answer is 48/72
remember there is 3 step:keep 
                                     change
                                     flip

in a card game,each player is dealt 5 cards.Make a table to show the total number of cards dealt for each number of players from 3 to 6.Write each ratio of players to cards dealt.

Answers

so since each player is dealt 5 cards
ratio of cards per player is 5:1

so if 3 players
5 times 3=15 cards

4 players=4 times 5=20 cards

5 players=5 times 5=25 cards

6 players=6 times 5=30 cards


ratio of cards per player is 5:1
since each palyer gets 5 cards each then 3 people is 15 cards & 4 people is 20 cards & 5 people is 25 cards and 6 people is 30 cards all together so there will be 30 cards all together 3:15                                                                                                                                      4:20                                                                                                                                      5:25                                                                                                                                          6:30
