A bag contains pennies, nickels, dimes and quarters. There are 50 coins in all. Of the coins 16% are pennies and 42% are dimes. There are 5 more nickels then pennies. How much does the bag contain

Answer:

you substitute x for 4

Step-by-step explanation:

so its f(x) and f(4) so you use 4 for x so you would solve f(x)=3(4)+2

Answer:

13.75

Step-by-step explanation:

The expected value of the hourly wage is the sum of the probabilities (percentage of time spent on each job) multiplied by the payoff (money earned) from each possible occurrence (job):

(0.6 × 11) + (0.25 × 19) + (0.15 × 16) = $13.75.

Answer:

17/20

Step-by-step explanation:

[tex]\frac{25}{100} + \frac{6}{10}[/tex]

to solve this multiply both fractions by 100

(25 + 60) / 100 = 85/100

we need to find the lowest common multiple

Both the numerator and denominator can be divided by 5 = 17/20

Answer:

75%

Step-by-step explanation:

Madison got 18 problems right and there's 24 problems in total. The question asks for the percentage of the problems that she answered correctly. So, put the number of questions that she got right and the total number of questions into a fraction and simplify.

18/24=3/4

3/4ths= 75%

Answer:

The first blank is 1/4, The second blank is also 1/4, the Final blank is 9

Step-by-step explanation:

If there are 4 quarts in a gallon, you multiply 1/4 by 36 because a quart is 1/4 of a gallon

36 multiplied by 1/4 is 9

Answer:

72.24

Step-by-step explanation:

Price for each camera = 14

Number of camera = 2dozen = 12 x 2 = 24

Total cp = 24 x 14 = 336

~~~~~~~~~~~~~~

Price for each camera=  10.99

Number of cams = 24

Total sp = 10.99 x 24 = 263.76

Loss = 336 - 263.76  = 72.24

Answer:

126 :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

first find angle ∠U,

As sum of angle in triangle = 180°

Now ∠U+∠V+∠W=180°

88°+38°+∠U=180°

∠U=54°

Now total horizontal line = 180°

∠NUV=180°-54°=126°

Answer:

it's b

Step-by-step explanation:

the reason it's b is because conduction happens when something hot comes in contact with something cold which heats the cold thing up and cooling the hot thing eventually they will both be room temperature

The claim can be determined by the probability method which will determine the percentage of battery lasting to an average of 16 hours.

Step-by-step explanation:

Probability method in statistics helps to determine the percentage of an event in certain circumstances. In the given scenario the claim is made that battery lasts an average of 16 hours. This claim can be verified by the probability check though standard deviation from the observation.

Answer:

$819

Step-by-step explanation:

45.5 *18=819

Answer:

15x^7y^11

Step-by-step explanation:

First, multiply the coefficients 5 and 3 together.  We get:

15x^4y^3 * x^3y^8

Please note that it's mandatory to use " ^ " to indicate exponentiation.

Since x^4*x^3 = x^7, we next obtain:

15x^7y^11

Answer:

Use M A T H W AY

trust me its goated

Answer:

None of the above, it should be $4760

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 12%/100 = 0.12 per year,

then, solving our equation

I = 3500 × 0.12 × 3 = 1260

I = $ 1,260.00

The simple interest accumulated

on a principal of $ 3,500.00

at a rate of 12% per year

for 3 years is $ 1,260.00

Answer:

x^2-5x+33

Step-by-step explanation:

(x-4)^2 -5x+20-3

x^2-4^2

Answer:

3x (x-3)

Step-by-step explanation

3x^2 - 9x + 0

The equation.

3x^2 - 3^2 × x

What I did here is that I factored out 9x to 3^2 times x.

3x (3x^2 all over 3x - 3^2 × x/ all over 3x)

So that way I can divide the number in the parentheses by 3x to take 3x out of the parentheses to factor out.

3x (x^2-1 - (3^2-1) )

You simplify to get the final answer.

3x (x-3)

Final Answer.

I hope this helps!!!!

Answer:

Step-by-step explanation:

1. 1 Simplify  2+6-4d to  -4d+8.

7 ( -4d + 8)

therefor, the answer is, 7( -4d + 8)

Answer:

7(2 + 6 - 4d) = 7(8 - 4d) = (56 - 28d)

Step-by-step explanation:

There is no possible answer to this equation but this is the most accurate equation, since you cant go any further, this is your simplified form.

Answer:

5/8

Step-by-step explanation:

8/8-3/8=5/8

Răspuns:

292,50

Explicație pas cu pas:

Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17

Suma principală depusă, P = 250

Suma totală, A după 1 an poate fi calculată astfel:

A = P (1 + rt)

Unde ; r = rata dobânzii; t = timp

A = 250 (1 + (0,17 * 1))

A = 250 (1,17)

A = 292,5

Answer:

To me it Looks about 50 degrees from 80 degrees but im not positive though but i hope this helps you in some way or form.

Step-by-step explanation:

Given:

The probability that Jamil will be late for work is 0.2.

To find:

The probability that Jamil will not be late for work.

Solution:

We have,

P(Jamil will be late) = 0.2

We know that,

P(Jamil will not be late) = 1 - P(Jamil will be late)

                                       = 1 - 0.2

                                       = 0.8

Therefore, the probability that Jamil will not be late for work is 0.8.
