a collection of dimes and nickels is worth $8.40 there are 106 coins how many of each are there

Answers

Answer 1
There are 62 dimes and 44 nickels.

N + D = 106 (There are 106 coins in all.)
1 nickel = 5 cents.
1 dime = 10 cents.
5*N + 10*D = 840 ($8.40 = 840 cents)
N + D = 106 -------(1)
N = (106 - D)
5*N + 10*D = 840 ---------(2)
5*(106-D) + 10*D = 840
530 - 5*D + 10*D = 840
5*D = 840 - 530
5*D = 310
D = 310/5 = 62
Eq(1) N + D = 106
N + 62 = 106
N = 106 - 62
N = 44

IF YOU ANSWER WITHOUT A PROPER ANSWER AND YOU JUST WANT POINTS YOUR ANSWER WILL BE REPORTED! 99 POINT QUESTION! So I want a full explanation, best answer gets to be the brainliest. How much is 457 - (-54) + 7700 * 325 = ? I feel generous today so I'm making this 99 points. Btw, this is my first question asked here on brainly.

Answers

First you rewrite the question so it would be
457 + 54 + 7700 * 325 = x
So then you multiply 7700* 325 which would be 2502500
Then it is 457 + 54 + 2502500
So , 457 + 54 = 511
And 511 + 2502500 = 2503011 
Did this help ?
457 - (-54) + 7700 * 325 

So for this question you have to use PEMDAS, in other words, order of operations. PEMDAS means you have to do parentheses first, then exponents, then multiplication and division, and them addition and subtraction.

You have to  to start with the multiplication first since that is what comes first in this question.

457 - (-54) + 7700 * 325 turns into
457 - (-54) + 2502500

Afterwards you continue with addition and subtraction.

So, 457 - (-54) + 2502500 turns into
511+2502500
The reason 457 - (-54) equaled 511 is because negatives cancelled out and became a addition sign.

You finish off by 511+2502500

Your final answer would be 2503011

Two years ago Carol's living expenses were $ 1200 $ 1200 per month. This year the same items cost Carol $ 1400 $ 1400 per month. What was the annual inflation rate for the past two years?

Answers

inflation = ((price index difference / price index in base year) x 100) / period
             = ((200 / 1200) x 100) / 2
             = 8.33%
Given:
2 years ago - consumer price index 1,200 per month
current year - consumer price index 1,400 per month

Inflation rate = [(Consumer price index current - Consumer price index previous) / Consumer price index previous ] * 100%

Inflation rate = [(1400 - 1200) / 1200] * 100%  = (200 / 1200) * 100% =  16.67%

Since 2 years has passed, the 16.67% inflation rate is good for 2 years. We simply divide the inflation rate by 2 to get the annual inflation rate.

16.66% / 2 = 8.33%

The annual inflation rate for the past two years is 8.33%

Final answer:

The true statements about the opposite of -12 are that the opposite of the opposite of -12 is -12 and -12 and its opposite are located the same distance from zero on a number line. The opposite of -12 is +12.

Explanation:

In mathematics, the opposite of a number is also called its additive inverse, which is the number that, when added to the original number, will result in zero. −12 and its opposite, +12, are indeed located on opposite sides of zero on a number line, not on the same side. The second statement is true, the opposite of the opposite of −12 is indeed −12. The third statement is incorrect, the opposite of −12 is +12, not −112. The fourth statement is also true, −12 and its opposite are both 12 units away from zero on a number line, so they're at the same distance from zero.

A hurricane has a large eye of about 80 miles. How many kilometers wide is the eye?

Answers

It is given that a hurricane has a large eye of about 80 miles.

We have to determine about how many kilometers wide is the eye.

Since 1 mile = 1.6 kilometers (approximately)

To convert the unit 'mile' into 'kilometer' ,

we have to multiply the given number by '1.6'.

So, 80 miles = [tex] 80 \times 1.6 = 128 [/tex] kilometers.

So, the hurricane eye is about 128 kilometers wide.

Final answer:

To convert 80 miles to kilometers, multiply by the conversion factor of 1.60934, resulting in an eye of the hurricane that is approximately 128.75 kilometers wide.

Explanation:

To convert the size of a hurricane's eye from miles to kilometers, we use the conversion factor that 1 mile is approximately equal to 1.60934 kilometers. If a hurricane has an eye that is about 80 miles wide, we need to multiply this distance by the conversion factor to obtain the width in kilometers.

Step-by-step Conversion:

Identify the width of the hurricane's eye in miles: 80 miles.

Use the conversion factor: 1 mile = 1.60934 kilometers.

Multiply the width in miles by the conversion factor to get the width in kilometers: 80 miles * 1.60934 km/mile = 128.7472 kilometers.

Therefore, the eye of the hurricane is approximately 128.75 kilometers wide.

That would be 82/100 so .82
And mutlypy by 100% is 8.20 so it's 8%
Have a nice day

The population of the small town percent decreased by approximately 8.4%.

To find the percent decrease in the population of the small town, we can use the formula for percent decrease:

Percent Decrease = [(Initial Value - Final Value) / Initial Value] * 100

Given that the initial population was 983 and the final population was 901, we can plug these values into the formula:

Percent Decrease = [(983 - 901) / 983] * 100

Now, calculate the numerator:

Percent Decrease = [82 / 983] * 100

Divide and multiply:

Percent Decrease = 0.0835 * 100

Now, calculate the percent decrease to the nearest tenth of a percent:

Percent Decrease ≈ 8.4%

From the sample space sequals=​{1, ​2, 3,​ 4,..., 15} a single number is to be selected at random. given event​ a, that the selected number is​ even, and event​ b, that the selected number is a multiple of​ 4, find ​p(upper a vertial line upper ba∣b​).

Answers

Given
E={1,2,3,4,5....14,15}....   sample space
A={2,4,6,...14}  ..... even numbers
B={4,8,12}  ............multiples of 4
To find: P(A|B)

We deduce from above that 
P(A)=7/15
P(B)=3/15
P(A &cap; B)=3/15  since B is a subset of A.


The conditional probability P(A|B) is the probability of A happening given B has already happened.  
So if a number has been selected, and it is known that B has happened, (i.e. multiple of 4), we know that there is a 100% probability A has happened (even).

Mathematically, P(A|B) is defined as P(A &cap; B)/P(B).
So 
P(A|B)
=P(A &cap; B)/P(B)
=(3/15)/(3/15)
=1   (as reasoned above).

Answer: P(A|B)=1
Final answer:

The probability of randomly selecting an even number given that the number is a multiple of 4, or p(A|B), is 1.

Explanation:

The question is asking for the conditional probability p(A|B), meaning the probability of event A (number is even) given that event B (number is a multiple of 4) has already occurred. In this sample space, there are 8 even numbers {2, 4, 6, 8, 10, 12, 14, 16} and 4 multiples of 4 {4, 8, 12, 16}. Therefore, the probability of picking an even number out of the ones that are multiples of 4 is as follows:

First, determine the probability of event A within event B by dividing the number of favorable outcomes (even numbers and multiples of 4) by the total outcomes of event B. In this case, all multiples of 4 are even numbers, so there are 4 favorable outcomes.

Calculating p(A|B): Number of instances where A and B occur together / Number of instances where B occurs = 4 / 4 = 1

Therefore, the probability of randomly selecting an even number given that the number is a multiple of 4, p(A|B), is 1.

if f(x) = 5x^3-2 and g(x)= 2x+1, find (f+g) (x).

Answers

Hey there!

To start, whenever you are performing (f+g)(x), this means that you are to add the functions f(x) and g(x) together. 

In this case, f(x) is equal to 5x^3-2 and g(x) is equal to 2x+1.

Because you are adding the two expressions as according (f+g)(x), you should set up this expression:
(5x^3-2)(2x+1)

Now, combine your like terms (terms of the same variables that are all raised to the same power):
(5x^3-2)(2x+1)
=5x^3+2x-1

Therefore, (f+g)(x)=5x^3+2x-1

Answers

Final answer:

To find the length and width of a rectangle given its area and the relationship between its dimensions, set up and solve an equation by following the step-by-step process.

Explanation:

Given: The width of a rectangle is 3 inches less than its length and the area is 340 square inches.
To solve: Let the length be 'x' inches, then the width is 'x - 3' inches. Set up the equation 'x(x - 3) = 340', solve for 'x' to find the length and width.

Step-by-step:

Express the area as a product of the length and width: 'x(x - 3) = 340'.Expand and rearrange the equation: 'x^2 - 3x - 340 = 0'.Factor the quadratic equation: '(x + 17)(x - 20) = 0'.Solve for 'x': 'x = -17' or 'x = 20'. Since length cannot be negative, the length is 20 inches.Calculate the width: '20 - 3 = 17 inches'.

Jin's expression is 1.05h.

The variable h represents the cost of the hat.

1.05 represents 100% of the cost of the hat plus the additional 5% tax; 100+5 = 105%; 105% = 105/100 = 1.05.

Together the total cost is given by 1.05h.

Answers

the complete question in the attached figure

Let
x--------------------- > non-fiction books.------------------ > x=60
y--------------------- > fiction books.
we know that 
x+y=100
y=100-x=100-60=40
the fiction books. are y=40

if 100%----------------------- > 100 books
  X---------------------------- > 40
X=40*100/100=40%

40%-------------- > 40/100=20/50=2/5

the answer is
the fraction of the books that are fiction is (2/5)

Solve the following word problem. A man travels from Town X to Town Y at an average rate of 50 mph and returns at an average rate of 40 mph. He takes a 1/2 hour longer than he would take if he made the round trip at an average of 45 mph. What is the distance from Town X to Town Y?

______ miles

Answers

Distance from Town X to Town Y = 100 miles

Distance = Speed x Time

Speed while going = 50 mph , Speed while returning = 40 mph

Let the time taken while going = t hours

So, the time taken while returning = t + 0.5 hours

Distance while going = Distance while coming back

So, 50 t = 40 ( t + 0.5)

50 t = 40x + 20

50 t - 40 t = 10x = 20

10 t = 20

t = 20 / 10 = 2

Hence, distance = 50 t = 40 ( t + 0.5 )

= 50 x 2 ; or 40 x 2.5 = 100

Final answer:

The distance from Town X to Town Y is 180 miles. This is determined by setting up and solving an equation based on the given speeds and time difference.

Explanation:

The subject of this question is Mathematics, specifically it is a problem in a genre called distance, speed, time problems. Let's denote the distance from Town X to Town Y as 'd' miles. The man covers this distance twice - once going and once coming back. The time he takes to travel from X to Y is d/50 and to travel back from Y to X is d/40.

So, the actual total time he spends travelling is (d/50 + d/40) hours. If he made the round trip at an average speed of 45 mph, he would take (2d/45) hours (distance = speed x time). Given that the actual journey took a 1/2 hour longer than this, we can create the following equation:

(d/50 + d/40) = 2d/45 + 1/2.

Solving this equation for 'd', we get d = 180 miles. So, the answer is that the distance from Town X to Town Y is 180 miles.
