A collection of 40 dimes and nickels
is worth $2.90. How many nickels are
there? (Hint: In your equation, use
290¢ instead of $2.90.)

Answers

Answer 1

9514 1404 393

Answer:

22 nickels18 dimes

Step-by-step explanation:

Let d represent the number of dimes (the higher-value coin). Then the number of nickels is 40-d, and the total value in cents is ...

  5(40 -d) +10(d) = 290

  200 +5d = 290

  5d = 90

  d = 18

  40 -d = 22

There are 22 nickels (and 18 dimes).

_____

Additional comment

If you write the equation in terms of the number of nickels (n), you end up with the equation -5n = -110. The formulation used above avoids negative numbers, which can be confusing for some people.

The value of the trigonometric equation after transformation is given by the value y = 3 [ sin ( x + 3 ) ] - 2

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the parent function be represented as f ( x )

Now , the value of the trigonometric function f ( x ) is

f ( x ) = 3sin ( x )

when the function is translated 3 units to the left and 2 units down , we get

y = 3 [ sin ( x + 3 ) ] - 2

Therefore , the transformed function is y = 3 [ sin ( x + 3 ) ] - 2 and the graph is plotted

Hence , the transformed function is y = 3 [ sin ( x + 3 ) ] - 2

Answers

Answer:

-25 and 4

Step-by-step explanation:

Two numbers that multiply to the value on top and add to the value on bottom

Value on top = -100

Value at bottom = -25

Numbers that multiply to give -100 = -10 × 10, -20 × 5, -25 × 4, - 50 × 2,

Of all the above, - 25 × 4 = -100

-25 + 4 = -21

Value at bottom = -25

Therefore, the two numbers are -25 and 4

-25 × 4 = -100

-25 + 4 = -21

Answer:

x = 125

Step-by-step explanation:

Kindly check the image below

The problem we are looking at gives us the value of two intercepted arcs and wants us to find x ( which is an interior angle )

According to the image we can find an interior angle by adding the two intercepted arcs and then dividing the sum by 2

( Note that we are not given the direct intercepted arcs  of x. We are given the intercepted arcs of x's supplementary angle )

That being said we need to find x's supplement in order to find x

Using the image below as a reference

x's supplement = [tex]\frac{70+40}{2}[/tex]

[tex]70 + 40 =110\\\frac{110}{2} =55[/tex]

So x's supplement = 55

Now to find x

Remember that supplementary angles have a sum of 180°

That being said we can find the missing angle (x) by subtracting the given angle (55) from 180

so x = 180 - 55

180 - 55 = 125

Hence x = 125

There were 6 marbles in a bag for read into were blue what is the probability that you will pull out a blue marble

Answers

Question: There were 6 marbles in a bag four were red two were blue what is the probability that you will pull out a blue marble

Answer:

Pr(blue) = 1/3

Step-by-step explanation:

From the question,

Probability = Possible outcome/Total outcome

Pr(blue) = number of blue marbles(B)/Total number of marbles

Pr(blue) = B/N.................... Equation 1

Where B = Total number of blue marbles, n = Total number of marbles

Given: B = 2, n = 6

Substitute these values into equation 1

Pr(blue) = 2/6

Pr(blue) = 1/3.

Hence the probability that a blue marble will be pulled out is 1/3
