George has only Quarters and nickels in his piggy bank.He has a total of 90 coins.The value of the coins is $16.10. Write and so
son4ous [18]

Answer:

The number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

Step-by-step explanation:

It is important to note that:

A quarter is worth 25 cents = 0.25q

A nickel is worth 5 cents = 0.05n

George has only Quarters and nickels in his piggy bank.

Let the number of

Quarters = q

Nickels = n

He has a total of 90 coins.

Hence,

q + n = 90.... Equation 1

q = 90 - n

The value of the coins is $16.10.

Hence,

0.25q + 0.05n = 16.10....Equation 2

We substitute 90 - n for q in Equation 2

0.25(90 - n) + 0.05n = 16.10

22.5 - 0.25n + 0.05n = 16.10

Collect like terms

- 0.25n + 0.05n = 16.10 - 22.5

-0.2n = - 6.4

n = -6.4/-0.2

n = 32 nickels

Solving for q

q = 90 - n

q = 90 - 32

q = 58 quarters

Therefore, the number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

Rectangle Q has an area of two square units. Thea drew a scaled version of rectangle Q and labeled it rectangle R. what scale fa
belka [17]

Answer:

It is given that Rectangle Q has an area of 2 square units.

Thea Drew a scaled version of Rectangle Q and marked it as R.

As you must keep in mind If we draw scaled copy of pre-image, then the two images i.e Pre-image and Image are similar.

As you have not written what is the scale factor of transformation

Suppose , Let the Scale factor of transformation= k

Rectangle Q = Pre -image, Rectangle R= Image

If, Pre-Image < Image , then scale factor is k >1.

But If, Pre-Image > Image , then Scale factor will be i.e lies between, 0<k<1.

Give the coordinates for the image of R (0, -5) E (4, -3) C (6, -5) T (2, -7) when it is reflected across the line y = x.
SCORPION-xisa [38]

Answer:

Below.

Step-by-step explanation:

The x and y coordinates flip with this reflection e, g   (2, 1) goes to (1, 2).

So  R (0, -5) ---> R' (-5, 0).

     E (4, -3) ---> E' (-3, 4).

     C (6, -5) ---> C' (-5, 6).

    T (2, -7) ---> T' (-7, 2).
