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.

With a fair die, the probability of rolling any number 1 through 6 is the same. If P(1) represents the probability of rolling a 1, P(2) the probability of rolling a 2, and so forth, what is the value of: P(1) P(2) P(3) P(4) P(5) P(6)?.
Using probability theory, the value of P(1) P(2) P(3) P(4) P(5) P(6) is [tex](1/6)^{6}[/tex].
What is probability?
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].

perform the following operation and express the answer in scientific notation 3.60x10^-12+3.60x10^-11
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.

Find the measure of the numbered angles
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.

Find the equation of the line that is parallel to y=(2x-1)/3 and passes though (0,5)
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
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?
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.
What are independent events?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.

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}

Javier and his two friends are going to the basketball game. Each student pays $2 for their ticket and buys 3 snacks (all snacks cost the same). If all together, they spend $17.25, how much does each snack cost?
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

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

What type of transformation occurred if the quadratic parent function becomes y = 3x² + 9
Horizontal compression, vertical up
Vertical stretch, vertical up
Horizontal stretch, vertical down
Vertical compression, vertical down
Answer:
Horizontal compression, vertical up
Step-by-step explanation:
The 3 compresses the parent function
The 9 moves it up 9 Spaces
Answer:
Horizontal compression, vertical up . . . or ...Vertical stretch, vertical upStep-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.
Solve the system of equations using elimination. How many solutions does the system have?
15x + 12y = 18
5x + 4y = 6
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.
An angle measures 82º more than the measure of its complementary angle. What is the measure of each angle?
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?
❖ Explanation -:Given -:
An angle measures 82º more than the measure of its complementary angle.Need to find -:
Measure of each angleAssuming -:
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°
Final Answer -:
The angles are 4 and 86.[tex] \rule{180pt}{2pt}[/tex]

In a certain chemical, the ratio of zinc to copper is 3 to 19. A jar of the chemical contains 494 grams of copper. How many grams of zinc does it contain?
enter your response here
It contains grams of zinc.
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
