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

Independent events are ones whose occurrence is not contingent on the occurrence of another event. The two events A and B are independent.

Independent events are ones whose occurrence is not contingent on the occurrence of another event.

As it is given that the probability of event A occurring is 0.65, while the probability of event B occurring is 0.76. And the probability of both event A and event B occurring is 0.494.

We know that for two independent events the probability of both the events occuring is given by the formula,

[tex]\rm P(A\ and\ B)=P(A) \times P(B)[/tex]

Substitute the values of P(A) and P(B), we will get,

[tex]\rm P(A\ and\ B)=0.65 \times 0.76[/tex]

                   [tex]=0.494[/tex]

Since the probability of both the events occuring together is 0.494.

Hence, the two events A and B are independent.

Answer:

It is known that x+2 is not a factor of the function.

Step-by-step explanation:

Whenever a remainder is present after diving a problem, the divisor is not a factor of the overall polynomial. Since this applies in this case, x+2 is not a factor.

Answer:

  infinite solutions

Step-by-step explanation:

The coefficient of x in the first equation is 3 times the coefficient of x in the second equation. This means we can eliminate x by subtracting 3 times the second equation from the first:

  (15x +12y) -3(5x +4y) = (18) -3(6)

  0 = 0 . . . . . simplify (true for all values of x or y)

Answer:

YB= 11.2

Step-by-step explanation:

These triangles use scale factors.

Using scale factors, we can see that 7/15 is as (7+YB)/(15+24). Those are equal fractions, so we can set them equal to each other and solve for YB.

(7/15)=((7+YB)/(39)) solving for YB we get that it is equivalent to 11.2.

Answer:

Horizontal compression, vertical up

Step-by-step explanation:

The 3 compresses the parent function

The 9 moves it up 9 Spaces

Answer:

Step-by-step explanation:

The transformation to the parent quadratic function can be described either of two ways. For a quadratic, a vertical stretch can also be accomplished by a horizontal compression.

The transformations of interest here are ...

  g(x) = a·f(x) . . . . vertical stretch by a factor of 'a'

  g(x) = f(a·x) . . . . horizontal compression by a factor of 'a'

  g(x) = f(x) +a . . . . vertical translation by 'a' units

__

It is easy to see that the parent function f(x) = x^2 has had 9 added to it, so the function has been translated upward 9 units.

The transformation to 3x^2 can be accomplished either of two ways:

  3x^2 = 3(x^2) . . . vertical stretch by a factor of 3

  3x^2 = (x√3)^2 . . . . horizontal compression by a factor of √3

The attached graph shows either a horizontal compression or a vertical stretch will result in the same graph.

__

Additional comment

In the interest of using rational scale factors, we prefer the "vertical stretch, vertical up" description.

Answer:

Each snack cost $3.75.

Step-by-step explanation:

Javier and his two friends paid 6 bucks for their tickets in total.

If all together they spent 17.25 at the game, we can deduct 6 dollars from 17.25 so we can just get the snack total.

17.25-6=11.25

Since there are three people, and they bought 3 snacks, we can divide:

11.25/3=3.75

Each snack cost $3.75

Answer:

3.60X10^-12 is equal to 0.360X10^-11 (move decimal one place left)

Step-by-step explanation:

Now you can add 3.60X10^-11 and 0.360X10^-11:

3.60X10^-11 + 0.360X10^-11 = 3.96X10^-11

You're really just adding 3.60 to 0.36 since the "X10^-11" is the same for both.

Answer:

Step-by-step explanation:

Corresponding angles: When two parallel lines are intersected by a transversal, the acute angles on the same side are congruent & the obtuse angles on the same side of the transversal are congruent and they are called corresponding angles.

Co-interior angles: The interior angles on the same side of the transversal are called co -interior angles and they are supplementary.

a) c + 123 =  180    {linear pair}

 c = 180 - 123

c = 57

a = 123 {Corresponding angles}

b = a   {Vertically opposite angles are congruent}

b = 123

b) f + 82 = 180   {Linear pair}

f  = 180 - 82

f = 98

d = f        {Corresponding angles}

d = 98

e = d   {Vertically opposite angles}

e = 98

c) h = 75   {Corresponding angles}

g = h {Vertically opposite anges}

g = 75

Using probability theory, the value of P(1) P(2) P(3) P(4) P(5) P(6) is [tex](1/6)^{6}[/tex].

Probability is the measurement of possibilities or chances.

Probability = [tex]\frac{FavourableOutcomes}{TotalOutcomes}[/tex]

In case of a die, favorable outcomes are 1 or 2 or 3 or 4 or 5 or 6 i.e. 1

Total outcomes are {1,2,3,4,5,6} ie 6

From the above formula,

Probability P(1) of rolling a 1 = 1/6

Probability P(2) of rolling a 2 = 1/6

Probability P(3) of rolling a 3 = 1/6

Probability P(4) of rolling a 4 = 1/6

Probability P(5) of rolling a 5 = 1/6

Probability P(6) of rolling a 6 = 1/6

P(1)P(2)P(3)P(4)P(5)P(6) = [tex]\frac{1}{6} *\frac{1}{6}*\frac{1}{6}*\frac{1}{6}*\frac{1}{6}*\frac{1}{6} = (\frac{1}{6} )^{6}[/tex]

Therefore, the value of P(1) P(2) P(3) P(4) P(5) P(6) is [tex](1/6)^{6}[/tex].

Answer:

Step-by-step explanation:

Answer:

Well in a 30-60-90 triangle there are 2 rules

The short leg is “x” (for now)

The hypotenuse leg is twice the shorter leg (2x)

And the longer leg is x√3

Now using that information we can tell that the hypotnuse here is 19. It’s flipped over.

We know that x is the shorter leg here. So its half of the hypotnuse (19).
19/2 = 9.5

X= 9.5

Answer:

1-90

2-55

3-35

Step-by-step explanation:

All the angles added up in one triangle should equal 180. Since you know 1 is a 90 degree angle, you add 90 and 55 to get 145, then subtract 145 from 180  to get 35. Two is 55 because the two angles are the same length. 3 is 35 because it is the unknown angle.

Answer:

y = (2/3)x + 5

Step-by-step explanation:

y = (2x - 1)/3 is also

y = (2/3)x - 1/3

to get started on this question you will want to plug in the points and remove the - 1/3 as the slope is the same

5 = 0 + b

the b is the y intercept or what was -1/3 in the previous equation

thus when you write the equation for the line that is parallel to y=(2x-1)/3 and passes though (0,5)

you get

y = (2/3)x + 5

Answer:

x=91/36

Step-by-step explanation:

Answer: The numbers are 5, 8, and 9

Step-by-step explanation:

x+y+z=22

y=x+3

z=2x-1

After you have those three equations, you can plug the y and z value into the first equation.

You get x+x+3+2x-1=22, so 4x+2=22

Therefore, 4x=20, so x=5

If x=8, then y=5+3, so y=8

Also, z=2(5)-1, so z=9
