Adrianna has $16 worth of quarters and dimes. If Adrianna has 21/2 times as many dimes as she does quarters, how many quarters does she have?​

Answers

Answer 1

Answer:

32 quaters

Step-by-step explanation:

We have two unknowns, the number of quarters, Q and the number of dimes, D.

Since we have two unknowns, we need to come up with two equations using these unknowns

1st Equation) We know that 1 quarter = 0.25 dollars, 1 dime = 0.10 dollars and that Adriana has 16 dollars:

   0.25 *Q + 0.10 * D = 16 dollars

2nd Equation) The problem also states that Adriana has two and half (2.5) times as many dimes than quarters:

  D =2.5 * Q  

Substitute Equation 2 into Equation 1 and solve for Q, the number of quarters

0.25 * Q + 0.10 * (2.5 * Q) = 16.00

(0.25 + 0.25) Q = 16

0.5 * Q = 16

Q = 16 / 0.5 = 32

Adriana has 32 quarters.

Adriana also she  2.5 * 32 dimes, which means she has 80 dimes

Check the  results

0.25 * 32 + 0.10 *80 = 16.00

8.00 + 8.00 = 16.00

16.00 = 16.00

What is the ordered pair of the final point?

Answers

Using translation concepts, it is found that the ordered pair of the final point is given by:

D. (5,4).

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this situation, considering that we start at point (5,4), the translations are as follows:

5 units east, hence x = x + 5 = 10.4 units south, hence y = y - 4 = 0.4 units west, hence, x = x - 4 = 6.4 units north, hence y = y + 4 = 4.1 unit west, hence x = x - 5 = 5.

It ends at the starting point, hence option D is correct.

Step-by-step explanation:

The value of an amount earning interest continuously compounded is given by the formula ...

  A = Pe^(rt)

The value of P can be found by dividing by its coefficient:

If you are given the graph of g (x) = log Subscript 2 Baseline x, how could you graph f (x) = log Subscript 2 Baseline x 5? Translate each point of the graph of g(x) 5 units up. Translate each point of the graph of g(x) 5 units down. Translate each point of the graph of g(x) 5 units left. Translate each point of the graph of g(x) 5 units right.

Answers

The function that translates every point of the function f(x) 5 units above can be represented by g(x)=log₂x + 5.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

As the function that is given to us is f(x)=log₂x, therefore, the function can be written as,

[tex]y=f(x)=\rm log_2x[/tex]

Now, since we need every point to be up by 5 units, therefore, every value of x should be +5 on the y axis, therefore, the function that will represent that every point up by 5 units of the function f(x) can be written as,

[tex]g(x) = y+ 5\\\\g(x) = f(x) + 5\\\\g(x) = {\rm log}_2x + 5[/tex]

Hence, the function that translates every point of the function f(x) 5 units above can be represented by g(x)=log₂x + 5.

We also know they made 0.5 for each animal so sales made / price = number sold
2X + X = 48/0.5
3X = 96
X = 32
So Randi made 64 And her sister made 32.

The equation having a sum that is a whole number is 0/5 + 1/5 + 2/5 + .... + 5/5

What is an whole number?

A whole number means a number that does not include any fractions, negative numbers or decimals.

Given that, number sentences show a pattern in the sum of the fractions from 0 to 1 for different denominators,

1) 0/5 + 1/5 + 2/5 + .... + 5/5 =

1/5(0 + 1 + 2 + 3 + 4 + 5) = 1/5(15) = 3 [whole number]

2) 0/6 + 1/6 + 2/6 + .... + 6/6 =

1/6(0 + 1 + 2 + 3 + 4 + 5 + 6) = 21/6 = 7/2 [fraction]

3) 0/8 + 1/8 + 2/8 + .... + 8/8 =

1/8(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8) = 36/8 = 9/2 [fraction]

4) 0/12 + 1/12 + 2/12 + .... + 12/12 =

1/12(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12) = 78/12 = 13/2 [fraction]

Triangle 2: 16, 18, 24

16/18 = 8/9

18/24 = 3/4
