At a football stadium, 4% of the fans in attendance were teenagers. If there were 120 teenagers at the football stadium, what was the total number of people at the stadium?

9514 1404 393

Answer:

  43.2 grams

Step-by-step explanation:

The exponential equation for the decay can be written as ...

  amount remaining = (initial amount)(1 -decay rate)^t

  = 570(1 -0.18)^t

We want to find the amount remaining after 13 minutes. Evaluating this equation for t=13, we have ...

  amount remaining = 570(0.82^13) ≈ 43.2 . . . grams

Answer:

His time in mph is 16.1 mph

Answer:  [tex]-\frac{p}{8}[/tex]

This is the fraction -p/8

====================================================

Explanation:

When we divide by -16, we're really multiplying by -1/16. Fractions and division are very similar ideas.

So we can say,

[tex]2p \div -16 = 2p \times \frac{-1}{16}\\\\2p \div -16 = \frac{2p}{1} \times \frac{-1}{16}\\\\2p \div -16 = \frac{2p(-1)}{1*16}\\\\2p \div -16 = \frac{-2p}{16}\\\\2p \div -16 = \frac{-2p}{2*8}\\\\2p \div -16 = -\frac{p}{8}\\\\[/tex]

The second to last step has a pair of '2's divide and cancel out.

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

Another way to think of it is to consider

[tex]\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}[/tex]

The flip from division to multiplication has us apply the reciprocal of the second fraction. In this problem, we have a = 2p, b = 1, c = -16 and d = 1. The steps will be very similar if not identical to what is shown above.

Answer:

0.4

Step-by-step explanation:

Since there are 5 spaces between the 1 and 0, each tick represents [tex]\frac{1}{5}[/tex] or 0.2 units. Counting up from 0 you get 0.4

Answer:

Step-by-step explanation:

therefore, the answer is 0.4

Answer:

25 men

Step-by-step explanation:

100 - 65 = 35 women

60 - 35 = 25 men

Answer: 25

Step-by-step explanation:

Amount of ppl: 100

Men: 65

Woman: (100-65) =35

People paid (all woman are in this group) 60

Woman paid: 35

Men paid: (60-35) =25

Step-by-step explanation:

Percentage increase = (279 - 180)/180 x 100% = 55%

this is a topic on percentage. the above question requires a use of a kind of formula if you wish to explore more into this topic you can give me a follow on Instagram (learntionary) I've already posted some notes on this topic and will be doing more on others and also I'll be providing tips on some topics as well!

Answer:

55% increase

Step-by-step explanation:

First I want to say I recommend using sites like Calculator soup, and finding the option "percent increase calculator", for problems like these instead of wasting any points that you could use later on, and Secondly (happy to help), oof and third:

1) subtract the final value minus the starting value

279 - 180= 99

2) Divide that amount by the absolute value of the starting value

99 divided by 180 equals .55

3) Multiply by 100 to get percent increase

changes to 55.00 (final answer 55%)

4) If the percentage is negative, it means there was a decrease and not an increase.

Step-by-step explanation:

Given

Rectangle A:

[tex]Length: 10\ in[/tex]

[tex]Width: 8\ in[/tex]

Required

Determine the possible dimensions of Rectangle B

The question has missing options; however, the question can still be solved.

Rectangle B being an enlarged copy of A implies that the dimension of A A is enlarged in equal proportion to form B

Take for instance, the measurements of Rectangle B are

[tex]Length: 15 in[/tex]

[tex]Width: 12 in[/tex]

Divide the corresponding lengths of B by A to get the enlargement ratio

[tex]Ratio = \frac{B}{A}[/tex]

For length:

[tex]Ratio = \frac{15}{10}[/tex]

[tex]Ratio = 1.5[/tex]

For width

[tex]Ratio = \frac{12}{8}[/tex]

[tex]Ratio = 1.5[/tex]

Notice that both ratios are the same.

For this measurement of B, we can conclude that B is an enlargement of A

Assume another measurements for B

[tex]Length: 20\ in[/tex]

[tex]Width: 10\ in[/tex]

Calculate Ratios

[tex]Ratio = \frac{B}{A}[/tex]

For length:

[tex]Ratio = \frac{20}{10}[/tex]

[tex]Ratio = 2[/tex]

For width

[tex]Ratio = \frac{10}{8}[/tex]

[tex]Ratio = 1.25[/tex]

Notice that, both ratios are not equal.

For this measurement of B, we can conclude that B is not an enlargement of A

Conclusively, all you have to do is: determine the ratios of the dimensions of B to A, if the result are equal then B is an enlarged copy of A; if otherwise, then B is not an enlarged copy

Answer:

$375.71

Step-by-step explanation:

Given that:

Rate of interest = 5.5% compounded quarterly

Time = 1.5 years

Principal amount deposited in savings account = 1.5 years

To find:

Interest earned = ?

Solution:

Formula for amount with interest compounding quarterly:

[tex]A = P(1+\dfrac{r}{4\times 100})^{4t}[/tex]

Putting the values:

[tex]A = 4400(1+\dfrac{5.5}{4\times 100})^{4\times 1.5}\\\Rightarrow 4400\times 1.01375^6\\\Rightarrow 4400\times 1.085\\\Rightarrow \$ \bold{4775.71}[/tex]

Interest earned = Amount - Principal

Interest earned = 4775.70 - 4400 = $375.71

Answer:

Step-by-step explanation:

sin(x) + tan(x) =sin(X) + sin(x)/cos(x)

=sinx(1+1/cosx)

=Sinx(1+secx)

=1+secx/cosecx. (Since sinx=1/cosecx)

Hence LHS=RHS proved

Answer:

42

Step-by-step explanation:

63 divided by 3 first because you need to break each group down into equal gardens with the same amount of butterflies.

now you have 21 you need to multiply with the number 2 because you need to know how many butterflies are in two gardens

and now you get 42

Dave is 27. His brother is 18.

Step-by-step explanation:

Dave is 9 years older than his brother, so if his brother is 18, he is 27. If you doubled the brother's age (18) you would get 36. Then you subtract 36 by 9 and get 27. <3
