A vending machine has $50.40 in it. There are 432 coins total and the machine only accepts nickels and quarters. How many nickels and quarters are in the machine?​

Answers

Answer 1
Nickels = n
Quarters = q

n + q = 432

Nickels are 5 cents (0.05)
Quarters are 25 cents (0.25)

0.05n + 0.25q = 50.40

Use substitution or elimination (I like substitution)
n + q = 432 means n = 432 - q

So 0.05n + 0.25q = 50.4 is
0.05(432 - q) + 0.25q = 50.4
21.6 - 0.05q + 0.25q = 50.4
21.6 + 0.2q = 50.4
0.2q = 28.8
q = 144

Plug in to find nickels
n + q = 432 means
n + 144 = 432
n = 288

An uses they equation y= 8.25x to calculate the total cost y in dollars for x posters. How much did she spend on 6 posters?

Answers

well if the equation is y=8.25x it means that you would multiply 8.25 x 6 to get the total cost of the posters.

8.25 x 6 = 49.50

49.50 would be the total cost! I hope this helps!

It will just a smaller piece of something but never everything. For example 1/8 of 1/100000 is still going to be a number. So, it will never sell all video games. This is a mathematical perspective, not a logical perspective since logically you cant sell a part of a video game.

Point A is (-9,-3) and is translated 4 left and 2 down. Where is A' at?

Answers

Answer:

A translation maps point A(3,7)A(3,7)A, left parenthesis, 3, comma, 7, right parenthesis to point A'(6,-2)A

(6,−2)A, prime, left parenthesis, 6, comma, minus, 2, right parenthesis. Let's determine what translation this is.

Step 1: Horizontal shift. AAA is shifted 333 units to the right because (6)-(3)=\tealD{+3}(6)−(3)=+3left parenthesis, 6, right parenthesis, minus, left parenthesis, 3, right parenthesis, equals, start color #01a995, plus, 3, end color #01a995.

I'm really struggling with this problem can someone please give me an examples like this problem or explain how to solve it an problems like it.

Answers

Answer:

Step-by-step explanation:

Ok so I'm not 100% sure how to solve this but what I would do is use the equation a^2 + b^2 = c^2 this equation is used to solve for the hypotenuse or the longest side of a triangle. To find a^2 you would do (21+15)^2 (Also this symbol ^ is the power symbol) and the answer would be 1296. b^2 would be 25^2 or 625. The equation turns out to be 1296 + 625 = c^2. c^2 (or x in this case) would be 1921. To find just c and not c^2 you would find the square root of 1921 which is 43.8292140016 or if rounded would be 43.8. Also this might not help if I misinterpreted the question...

what is g in this problem 4-(9g-5)=-18​

Answers

Step-by-step explanation:

Let's solve your equation step-by-step.

4−(9g−5)=−18

Step 1: Simplify both sides of the equation.

4−(9g−5)=−18

4+−1(9g−5)=−18(Distribute the Negative Sign)

4+−1(9g)+(−1)(−5)=−18

4+−9g+5=−18

(−9g)+(4+5)=−18(Combine Like Terms)

−9g+9=−18

−9g+9=−18

Step 2: Subtract 9 from both sides.

−9g+9−9=−18−9

−9g=−27

Step 3: Divide both sides by -9.

−9g−9=−27−9

g=3

g = 3

I have a pile of socks which contains 12 white socks, 12 black socks, and 12 red socks. How many socks must I take from the pile to be certain that I have at least one matching pair?

Answers

Answer:

I would say 6 but i do not know

Step-by-step explanation:

bc 6x2=12

The least number of socks to be taken from the pile to have one pair of socks is given by the equation A = 4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of socks to be taken be represented as A

Now , the equation will be

The number of white socks = 12

The number of black socks = 12

The number of red socks = 12

So , let the first sock be taken be either a white , black or red

Now , the second sock can also be either a white , black or red

And , the third sock can also be either a white , black or red

But , the fourth sock must a white or black or red and it will form a pair of similar colored sock

Therefore , the number of times is 4

Hence , the number is 4

In 1984 the average American used to eat 55.7 pounds of chicken. This was 2.8 pounds more than the 1982 average. By what percent did chicken consumption increase from 1982 to 1984?

Answers

To solve this, we need to use the z statistic. The formula for z score is:

z = (x – u) / s

where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2

z = (90 – 90.6) / 17.2

z = -0.035

From the standard distribution tables:

P (z = -0.035) = 0.4860

Therefore there is about 48.60 % chance that it will be less than 90 pounds

A group of people attempt to bake the largest vegan cake the used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. How many kilograms of cocoa powder and dates do they use?

Answers

Answer: 187 kilogram

Step-by-step explanation:

Let the kilogram of dates be represented by x.

Since they used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. The dates will be:

= 1/10 × x = 17

0.1x = 17

x = 17/0.1

x = 170 kilogram

Date = 170 kilogram.

Cocoa powder = 17 kilogram

The total kilogram of date and cocoa powder used will be:

= 170 + 17

= 187 kilogram

Let f be the function defined by f(x)=x^3+x^2+x. Let g(x)=f^-1(x), where g(3)=1. What is the value of g'(3)?

Answers

Answer:

1/6

Step-by-step explanation:

Given the function

f(x)=x^3+x^2+x

Get the inverse. Let y = f(x)

y = x^3+x^2+x

Replace y with x

x = y³+y²+y

Differentiate with respect to x

1 =3y²dy/dx + 2ydy/dx + dy/dx

1 = (3y²+2y+1)dy/dx

dy/dx = 1/3y²+2y+1

g'(x) = 1/3(g(x))²+2g(x)+1

If x = 3

g'(3) = 1/3(g(3))²+2g(3)+1

g'(3) =1/3(1)²+2(1)+1

g'(3) = 1/3+2+1

g'(3) = 1/6

Hence g'(3) = 1/6
