a. The the proportion that would be used is: 159/15 = 1272/x
b. See explanation for the cross product below.
c. Approximately 120 home runs will be hit.
What is a Proportion?A proportion can be defined as an equation that involves comparing two equal ratios that are equivalent to each other or set equal to each other.
a. To write a proportion that defines the situation described above, let x represent the number of runs he will hit in his career.
Therefore, we would have the following proportion:
159:15 = 1272:x
or
159/15 = 1272/x
b. Using the cross product, we can find the value of x as shown below:
159 × x = 1272 × 15
159x = 19,080
Divide both sides by 159
159x//159 = 19,080/159
x = 120
c. The number of runs he will hit in his career is: 120.

Given △ C AT ≅ △DOG, m∠C = 25° , and m∠O = 37° , what is the measure of ∠G?
enter your answer in the box.
m∠G = __°
Answer:
m∠G = 118°
Step-by-step explanation:
The congruence statement that says:
△CAT ≅ △DOG,
says not only that the triangles are the same shape and size, it also says //which// angles (and sides) are conguent.
Angle C and Angle D are the same. Angle A and Angle O are the same. And Angle T and Angle G are the same.
So in △CAT, Angle C is 25° and Angle A (same as O) is 37°.
Also, all the angles in a triangle add up to 180°.
25° + 37° + T = 180°
62° + T = 180°
T = 118°
And T corresponds to G, so AngleG is also 118°.

What is the solution to the system of equations y 1 3x 10 2x y 4?.
The solution to the system of equations y = 1/3x - 10 and 2x + y = 4 is (6, -8).
What is the system of equations ?A system of equations is a collection of two or more equations with a same set of unknowns.
What is a Subsitution method ?The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.
The given system of linear equations are :
y = 1/3x - 10 and 2x + y = 4
On solving two equations by using substitution method, It is given that
[tex]y = \frac{1}{3}x-10[/tex] … (1)
2x + y = 4 … (2)
Substituting (1) in (2)
⇒ [tex]2x + (\frac{1}{3}x-10) = 4[/tex]
By further calculation
⇒ [tex]2x + \frac{1}{3}x - 10 = 4[/tex]
⇒ [tex]2x + \frac{1}{3} x = 4 + 10[/tex]
⇒ [tex]2x + \frac{1}{3} x = 14[/tex]
Taking LCM
⇒ [tex]\frac{(6+1)}{3}x = 14[/tex]
⇒ [tex]\frac{7}{3}x = 14[/tex]
By cross multiplication
⇒ 7x = 14 × 3
⇒ 7x = 42
Divide both sides by 7
⇒ x = 6
Substitute the value of x in equation (1)
[tex]\Rightarrow\ y = (\frac{1}{3} \times (6) - 10)[/tex]
So we get
⇒ y = (2-10)
⇒ y = -8
Therefore, the solution to the system of equations is (6, -8).

Find the equation of the line passing through the given point and parallel to the given line.
( 1 , 9), y = 4
(-1 ,-3), y= 2
(4, -6), y = -5
Answer:
y = 9, y = - 3 and y = - 6
Step-by-step explanation:
a line with equation y = c is a horizontal line parallel to the x- axis.
c is the value of the y- coordinates the line passes through.
Thus parallel lines must also be horizontal with equation y = c
a line parallel to y = 4 passing through (1, 9 ) with y- coordinate 9 is
y = 9
a line parallel to y = 2 passing through (- 1, - 3 ) with y- coordinate - 3 is
y = - 3
a line parallel to y = - 5 passing through (4, - 6 ) with y- coordinate - 6 is
y = - 6
Write an equation of a line that is
parallel to y = 1/3x + 5 and goes
through (3,5)
A) y = -3x + 14
B) y = 1/3x + 4
C) y = 1/3x + 4/3
D) y = 3x + 1
E) y = 1/2x + 7/2
Answer:
Step-by-step explanation:
We'll look for an equation in the format y = mx + b where m is the slope and b the y-intercept. A characteristic of parallel lines is that they have the same slope. That means the same value of m for both equations.
The reference equation is y = 1/3x + 5, It has a slope of (1/3). This means the new line will also have a slope of (1/3), and so we can write:
y = (1/3)x + b
Any value of b will result in a parallel line to y = 1/3x + 5. But the new line comes with the requirement that it go through point (3,5). That's easily done if we choose the correct value for b, the y-intercept. We could graph the line to visually determine what value of b will make the line go through this point, or we can simply enter the given point in the above equation and solve for b:
y = (1/3)x + b (for point (3,5)
5 = (1/3)(3) + b
5 = 1 + b
b = 4
A b value of four will shift the line so that it intersects (3,5). See the attached graph.

Flaming Fish Emporium sold 15 fish on Monday and then received a shipment of 15 fish on Tuesday. If they started with an inventory of 365 fish on Monday morning, how many fish did they have at the end of the day on Tuesday?
Answer:
365
Step-by-step explanation:
As the amount of fish the emporium sold and received are the same, the inventory of fish has not changed. Therefore, the emporium has 365 fish at the end of the day on Tuesday.
Monday morning: 365 fish
After Monday's sales: 365 - 15 = 350 fish
Tuesday morning: 350 fish
After Tuesday's shipment: 350 + 15 = 365 fish
Answer:
End of Tuesday = 365 fishes
Step-by-step explanation:
Fishes in inventory,
→ n = 365 fishes
Let's take it as,
→ Monday (x) = 15
→ Tuesday (y) = 15
Forming the expression,
→ (n - x) + y
Let's solve the expression,
→ (n - x) + y
→ (365 - 15) + 15
→ 350 + 15
→ 365 fishes
Hence, there are 365 fishes.

The type of function that represents the bank account as a function of time is: this is an exponential function because there is a common ratio in the balance between the months.
How to determine the type of function?In order to determine the type of function that models or represents the bank account as a function of time, we would check whether or not there is a common difference or common ratio.
In Mathematics, a linear function is used to model a situation when there exist a constant or common difference between its consecutive terms. On the other hand, an exponential function there is used to model a situation when there exist a constant or common ratio between its consecutive terms.
For the common difference, we have:
d = 1,474.56 - 1,843.20 = -368.64
d = 1,843.20 - 2,304.00 = -460.8
Therefore, the bank account as a function of time is not a linear function.
For the common ratio, we have:
r = 1,474.56/1,843.20 = 0.8
r = 1,843.20/2,304.00 = 0.8

The rate of Sam in miles per hour is 10.13.
Based on the relation between the units feet and mile, firstly converting the distance in miles.
5380 feet = 1 mile
So, 63,756 feet = 63,756 ÷ 5380
Performing division to calculate the distance in miles
63, 756 feet = 11.85 miles
Now converting the time in hour. As per the known fact, 60 minutes = 1 hour
So, 70 minutes = 70÷60
70 minutes = 1.17 hours
Now, finding the rate in miles per hour = number of miles ÷ amount of time
Rate in miles per hour = 11.85 ÷ 1.17
Performing division on Right Hand Side of the equation
Rate in miles per hour = 10.13
