the area of a triangle is

baseline × height / 2

our baseline here is

5 + 9 = 14 ft.

the height is 12 ft.

so, the area is

14×12 / 2 = 14×6 = 84 ft²

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)

The system of equations has an infinite number of solutions.

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:

103 inches

Step-by-step explanation:

So, Since we know that 12 in = 1 foot

all we have to do is multiply 12 by 8. Think of it like: what will 8 sets of 12 blocks give us?

8 x 12 = 96

So, 8 feet is 96 inches.

Now, Just add the 7 inches into the 96 inches.

96+7 = 103 inches

and then you are done!

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:

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.

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:

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:

3216 grams of Zn

Step-by-step explanation:

It is not clear from the question if the ratio is based on the chemical formula, and is thus the ratio of atoms, or if it is based on mass (in g).  I'll assume it is based on the numbers of Zn and Cu atoms.

Let's convert the mass of copper, 494 grams, to moles of copper (representative of the number of atoms).  The molar mass of copper, Cu, is 63.55 grams/mole.  

Moles Cu =(494 grams)/(63.55 grams/mole) = 7.77 moles Cu

If zinc (Zn) is in a ratio of 19/3, we would have:

  (19 moles Zn/3 moles Cu)*(7.77 moles Cu) = 49.2 moles of Zn

The molar mass of zinc is 65.38 grams/mole

The mass of 49.2 moles of Zn is:

(49.2 moles Zn)(65.38 grams/mole) = 3216 grams of Zn

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

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:

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:

36ft2 (sos if im wrong!)

Step-by-step explanation:

area of triangle

base x height / 2

7 x 12 / 2 = 42ft2

area of rectangle

base x height

3 x 2 = 6ft2

42 - 6 = 36ft2

Answer:

Step-by-step explanation:

Let one angle be x

Other angle =x + 82

Complementary angles add up to 90

x + x + 82 = 90

2x + 82 = 90

     2x    = 90 - 82

     2x    = 8

         x = 8/2

x = 4

Other angle = x + 82

                     = 4 +82

                      = 86

The angles are: 4 , 86

An angle measures 82º more than the measure of its complementary angle. What is the measure of each angle?

Given -:

Need to find -:

Assuming -:

An angle measures 82º more than the measure of its complementary angle.

Let us assume one angle as x

Then other angle = (x + 82)

Solution -:

First we will make an equation

We know,

Complementary angles add up to 90°

x + (x + 82°) = 90°

→ x + x + 82° = 90°

→ 2x + 82° = 90°

→ 2x = 90° - 82°

→ 2x = 8

→ x = [tex]\cancel{\dfrac{8}{2}}[/tex]

→ x = 4

Substituting the value of x = 4

One angle = x = 4°

Other angle = x + 82° = (4 + 82)° = 86°

Step-by-step explanation:

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

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
