Andrea has six times as many dimes as quarters. if her dimes and quarters total $12.75, how many of each coin does she have?
Salsk061 [2.6K]
Since the question is asking for the no. of coins each, we can represent the numbers with variables.

number of quarters = x
number of dimes = 6x (because there as 6 times as many dimes as quarters)

Next we can multiply the variables by the value of each coin.

25x + 6(10)x = 1275
25x + 60x = 1275
(make sure the expressione quals 1275, not 12.75. A dime is not 10 dollars, nor is a quarter 25 dollars).
85x = 1275
x = 15

Now that we have the value for x, plug it back in.
Andrea has 15 quarters and 90 dimes.

Considering an arbitrary number system with the independent digits as 0,1 and x. What is the radix of the number system
Mandarinka [93]

Using it's concept, it is found that the radix of the arbitrary number system is of 3.

<h3>What is the radix of a number system?</h3>

It is the number of different digits that the system has, for example:

  • The binary system has radix 2, as it has digits 0 and 1.
  • The decimal digit has radix 10, as it has 10 digits from 0 to 9.

In this problem, the digits are 0, 1 and x, hence the radix of the arbitrary number system is of 3.

Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's \frac{x_1}{y}\;and\;\frac{x_2}{y} are two fractions in same terms.

Thus, \frac{x_1}{y}\div\frac{x_2}{y} {Divided by a fraction is equal to multiplied by its reciprocal}

=\frac{x_1}{y}\times\frac{y}{x_2}

Quotient is simply the quotient of their numerators.

Example could be:

\frac{2}{7}\div\frac{3}{7}

\frac{2}{7}\times\frac{7}3}

\frac{2}{3}

2 is first numerator and 3 is the second numerator.

Answer:

If 50.24cm = Circumference

Radius = 8cm

If 50.24cm^2 = Area

Radius = 4cm

Step-by-step explanation:

50.24cm what? Circumference? Area?

π = 3.14

2πr = Circumference

50.24 / 2π = r

r = 8

πr^2 = Area

50.24 / π = r^2

r^2 = 16

r = 4

What is the midpoint of equation if N(10, −14) and P(−16, −4)?
meriva

Answer:

The answer is

<h2>( - 3 , - 9)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x_1 + x_2}{2} , \:  \frac{y_1 + y_2}{2} ) \\

where

(x1 , y1) and (x2 , y2) are the points

From the question

N(10, −14) and P(−16, −4)

The midpoint is

M = ( \frac{10 - 16}{2}   \: , \:  \frac{ - 14 - 4}{2} ) \\  = (  - \frac{6}{2}  \: , \:  -  \frac{18}{2} )

We have the final answer as

<h3>( - 3 , - 9)</h3>

Hope this helps you
