A collection of dimes and quarters worth $9.25. There are 46 coins in all. Find how many of each there are. How many dimes are there?

Answers

If all were quarters, the value would be 46*$0.25 = $11.50. The actual value is $2.25 less than that. Replacing a quarter with a dime reduces the value by $0.15, so there must be $2.25/$0.15 = 15 dimes

There are 15 dimes.

Answers:
The formula is [f(-1)-f(-4)]/[3]
The value of f(-1) is 3
The value of f(-4) is -3
The average rate of change is 2

==============================================

Explanation:

For the first blank, we use the formula
[ f(b) - f(a) ]/[ b - a ]
where 'a' and 'b' are the endpoints for the x interval

In this case, a = -4 and b = -1. When you plug those values into the formula above, you get...
[ f(b) - f(a) ]/[ b - a]
[ f(-1) - f(-4)]/[ -1 - (-4) ] 
[ f(-1) - f(-4)]/[ -1+4 ]
[ f(-1) - f(-4)]/[ 3 ]
which is why the answer is choice C for the first blank

-------------------------------------------

To compute the value of f(-1), we draw a vertical line through -1 on the x axis. This vertical line crosses the diagonal function graph at the point (-1,3). The y value of this point is what we want. Plugging in x = -1 leads to y = 3. This is why f(-1) = 3
If you want, you can draw a horizontal line through (-1,3) and you'll see it touching 3 on the y axis.

-------------------------------------------

Follow similar steps as above to compute f(-4). Draw a vertical line through x = -4 on the x axis. Mark the point where the vertical line crosses the diagonal line. This point is (-4,-3). Optionally draw a horizontal line over til you hit the y axis and you'll find that y = -3 corresponds to x = -4

This is why f(-4) = -3

-------------------------------------------

We'll use the last three sections to compute the average rate of change. Everything combines together building up to this moment.

From the first part, we had the formula
[ f(b) - f(a) ]/[ b - a ]
[ f(-1) - f(-4)]/[ 3 ]

We can replace the "f(-1)" with 3 since we found that f(-1) = 3
Similarly, f(-4) = -3 so we can replace the "f(-4)" with -3

Doing those replacements and simplifying leads to...

[ f(-1) - f(-4)]/[ 3 ]
[ 3 - (-3)]/[ 3 ]
[ 3 + 3]/[ 3 ]
6/3
2

So the average rate of change is 2

Note: because the entire graph is a straight line, the average rate of change for any interval a < x < b is going to be equal to the slope m. In this case, the slope of the line is m = 2/1 = 2. We move up 2 units each time we move to the right 1 unit along the diagonal line.

Sam entered three functions into a graphing calculator, y1 = x + 2, y2 = x2 + 2, and y3 = 2x. A portion of the table created by those functions is shown below.

A rectangular table is six times as long as it is wide. If the area is 294 ftsquared​, find the length and the width of the table.

Answers

42 length   7 width
please respond back if it was correct

the width of a rectangular table is 7 feet and the length of a rectangular table is 42 feet.

The area of a rectangular table is 294 ft².

What is the area of a rectangle?

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Let the width of a rectangular table be x.

Then, six times as long as it is wide = 6x

Area of a rectangular table = 6x × x

⇒ 6x²=294

⇒ x²=49

⇒ x=7 feet

So, length=6x=42 feet

Therefore, the width of a rectangular table is 7 feet and the length of a rectangular table is 42 feet.

Identify one characteristic of exponential growth.

A. A graph that is an increasing curve
B. A common ratio between 0 and 1
C. A common ratio less than 0
D. A common difference greater than 0

Answers

A. Exponential growth is called growth because it increases, so A is correct.
B. A common ratio between 0 and 1 would result in decay, not growth
C. A common ratio less than one would just reflect the graph across the x-axis. It does not give any information about whether or not it is exponential growth.
D. Exponential growth functions have no common differences.

Thus, A is the correct answer.

Exponential growth features a quantity increasing at a constant growth rate. The correct answer is Option A.

Exponential growth is characterized by a situation where a quantity increases at a constant growth rate. It is often represented graphically by an increasing curve.

This means that as time progresses, the rate at which the quantity grows also increases. For example, the population of a species might grow slowly at first, but as it becomes larger, the growth rate accelerates.

Given the options in the question, the correct answer is:

Option A. A graph that is an increasing curve

Answers

The base areas are equal.The prisms have the same height. The lengths of corresponding edges are in a 1:1 ratio.The volumes are equal.

The two prisms are congruent means that they have the same measures of bases, height, faces and angles.

Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length.

So, for congruent prisms, the corresponding angles are expected to be of the same sizes and the corresponding sides are expected to be of the same length.

Therefore the correct statements are:

The base areas are equal.

The prisms have the same height.

The lengths of corresponding edges are in a 1:1 ratio.

The volumes are equal.

 (10⁰ + 10¹x 1¹⁰)
 (10⁰ + 10¹ + 1¹⁰)

Final answer:

After calculating the values of the expressions, they can be arranged in increasing order of their values as follows:

(10⁰x 10¹ x 1¹⁰), (10⁰ + 10¹x 1¹⁰), (10⁰ + 10¹ + 1¹⁰), (10 x 10¹).

Explanation:

To arrange the expressions in increasing order of their values, we must first calculate the value of each expression.

(10⁰ x 10¹ x 1¹⁰): Here, 10⁰ = 1, 10¹ = 10, and 1¹⁰ = 1 (since any number to the power of zero is 1). Multiplying these together, we get 1 x 10 x 1 = 10.(10 x 10¹): This equals 10 x 10 = 100.(10⁰+10¹+1¹⁰): Adding these values together gives us 1 + 10 + 1 = 12.(10⁰+10¹ x 1¹⁰): Following the rules of operations (multiply before adding), first calculate 10¹ x 1¹⁰ which equals 10 x 1 = 10, then add 10⁰ which is 1. So, this gives 1 + 10 = 11.

Now we can arrange the expressions in increasing order:

(10⁰x 10¹ x 1¹⁰) (10⁰ + 10¹x 1¹⁰) (10⁰ + 10¹ + 1¹⁰) (10 x 10¹)

Josefina spent 20 + 3b dollars on a pair of earrings and three blouses that cost b dollars each how much did she spend in all if each blouse cost 15 $

Answers

She spent $65.

Step by Step-

She spent $15 on 3 blouses, so you would multiply and get that she spent $45 on blouses.

You would then add that to the $20 she spent before, and get $65.

Therefore, she spent $65.

Hope this helps!!

Josefina spent $65 in total, with $20 on earrings and $45 on three blouses at the cost of $15 each.

Calculating Total Cost

Josefina spent a certain amount of money on a pair of earrings and three blouses. The cost of the pair of earrings is separate from the blouses and is a fixed amount of $20. Each blouse costs $15, and she bought three blouses. Therefore, the total cost for the blouses is 3 times $15, which equals $45. To find the total amount Josefina spent, we need to add the cost of the earrings to the cost of the blouses.

Total spent on blouses = 3 * $15 = $45

Cost of the earrings = $20

Total amount spent = Cost of the earrings + Total spent on blouses

Total = $20 + $45 = $65

Therefore, Josefina spent a total of $65 on her purchase.

During a basketball game a player makes 12 of 18 free throws attempted write the ratio as fraction reduced to the lowest term

Answers

To make this a fraction, let's put [tex] \frac{12}{18} [/tex] . We can divide both top and bottom by 6, leaving us with [tex] \frac{2}{3} [/tex] . This is as far as we can reduce it, making it your answer. I hope this helps!

Final answer:

The ratio of free throws made to free throws attempted by the player is 12/18, which can be reduced to its lowest terms by dividing both numbers by their greatest common divisor, 6, resulting in the reduced fraction 2/3.

Explanation:

To find the ratio of free throws made to free throws attempted, we start by looking at the numbers given: 12 made out of 18 attempted. We express this ratio as a fraction 12/18.

To reduce this fraction to its lowest terms, we need to find the greatest common divisor (GCD) that divides both numerator and denominator evenly.

In this case, the number 6 is the GCD of 12 and 18. Dividing both the numerator and the denominator by 6, we get 2/3.

Hence, the ratio of free throws made to free throws attempted, reduced to the lowest term, is 2/3.
