**Answer:**

1 3/4

**Step-by-step explanation:**

A certain tiger shark is 55 cm long at birth and grows 2.5 cm / year. A certain hammerhead shark is 25 cm long at birth and grows 5 cm/year. When will the sharks be equal in length?

Let x = time in years

Let y = length of the sea creatures

The equation for the length of the tiger shark is

[ Select ]

. The equation for the length of the spiny dogfish hammerhead shark is

[ Select ]

. Solving with elimination, the sharks will be equal in length when

[ Select ]

years have passed.

**Answer:**

**Step-by-step explanation:**

equation for tiger shark:

for each additional year, it grows by 2.5 cm so that would be shown as 2.5x. also it starts at 55 so you would have to add 55 to that 2.5x.

the equation would be y = 2.5x + 55

equation for hammerhead:

do the same process with the other numbers. this would be

y = 5x + 25

solve with elimination:

subtract the two equations, which would eliminate the y variable

y = 5x + 25

- (y = 2.5x + 55)

you get

0 = 2.5x - 30

solve that for x

2.5x = 30

x = 12 years

so the years that have passed is 12. to find the length, plug in x = 12 into one of the equations:

y = 5x + 25 becomes y = 5 * 12 + 25 = 60 + 25 = 85

so they will be 85 cm long each.

Find the equation of a line whose graph passes through the two points (2,-3) and (4,-8).

**Answer:**

y=-5/2x+2

y+3= -5/2. (x-2)

**Step-by-step explanation:**

**Answer:**

y=-5/2x+2

**Step-by-step explanation:**

y=mx+b, where m is slope, b is y-int and y and x are variables.

Step 1: plot your points

Step 2: draw a line thru them

Step 3: find the slope. -5/2. And your y-int. +2

Amy is traveling across the USA by train over the summer. She is keeping track of all of the stops on her trip. She has just completed stop 8 and the map shows she is 20% complete. How many total stops are on her trip?

Answer: 40

Step-by-step explanation: if 8 stops complete 20% of the map 100% is 5 times that so 8x5 is 40 so 40 stops in total

The **total number **of **stops **in her **trip **is 40.

A branch of mathematics known as **algebra** **deals **with **symbols **and the mathematical **operations **performed on them.

Variables are the name given to these symbols because they lack set values.

In order to **determine **the **values, **these **symbols** are also **subjected** to various addition, subtraction, multiplication, and division **arithmetic** **operations**.

Given:

Amy has just **completed** **stop **8 and the map shows she is 20% complete.

let the **total** **number **of **stops** be x

So, 20% of x = 8

20/100x= 8

1/5x = 8

x= 40

Hence, the **total number** of **stops **in her **trip** is 40.

refer to the attachmenthope it helpsThe **length **of **major axis** of the ellipse 2√32.

The **length **of** minor axis **of the ellipse 2√18.

**What is an ellipse?**

The standard form of the **ellipse **is defined as;

x² / a² + y² / b² = 1

Where, a < b

**Minor axis **of the ellipse = 2a

And, **Major axis** of the ellipse = 2b

Given that;

The **equation **of the **ellipse **is,

(x−3)² / 18 + (y+4)² /32 = 1

Now,

We can **compare **with the **standards **form of an **equation **of ellipse, we get;

a² = 18

a = √18

And, b² = 32

b = √32

Clearly, √18 < √32

That is; a < b

So, The** minor axis** of the ellipse = 2a

= 2√18

And, The **major axis **of the ellipse = 2b

= 2√32

Therefore,

The **length **of **major axis** of the ellipse 2√32.

The **length **of** minor axis **of the ellipse 2√18.

give answer to 1 d.p

**Answer:**

AB ≈ 5.6 cm

**Step-by-step explanation:**

Using the cosine ratio in the right triangle

cos62° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{12}[/tex] ( multiply both sides by 12 )

12 × cos62° = AB , then

AB ≈ 5.6 cm ( to 1 dec. place )

ABCD is a parallelogram. What is the measure of ∠ACD?

**Step-by-step explanation:**

Here

5x+16+7x-3+6x+5 = 180(being sum of triangle)

or, 18x=180-18

or, x= 162/18

so, x = 9

now,

here,

<ACD = <ACB(diagonals of parallelogram bisect eachother)

or, <ACD = 7x-3

or, <ACD = 7×9-3

or, <ACD = 63-3

So, <ACD = 60°

Which set of numerical values represents the minimum, lower quartile, median, upper quartile, and maximum, in that order, of the box plot of this data set?

51, 51, 53, 53, 54, 55, 55, 56, 58, 58, 58, 59, 60

**Answer:**

51, 53, 55, 58, 60

**Step-by-step explanation:**

The minimum is the lowest value in the data set, that is 51

The maximum is the largest value in the data set, that is 60

The median is the middle value of the data, arranged in ascending order. If there is no exact middle then it is the average of the 2 values either side of the middle.

51, 51, 53, 53, 54, 55, 55, 56, 58, 58, 58, 59, 60

↑ middle

median = 55

The lower quartile is the middle value to the left of the median

51, 51, 53, 53, 54, 55

↑

Q₁ = [tex]\frac{53+53}{2}[/tex] = [tex]\frac{106}{2}[/tex] = 53

The upper quartile is the middle value of the data to the right of the median

56, 58, 58, 58, 59, 60

Q₃ = [tex]\frac{58+58}{2}[/tex] = [tex]\frac{116}{2}[/tex] = 58

(2x+1)(3x+1)=35 using quandratic equation solve

**Answer:**

x = {-2 5/6, +2}

**Step-by-step explanation:**

To use the quadratic formula, it is helpful to write the equation in standard form.

(2x +1)(3x +1) = 35

6x^2 +5x -34 = 0 . . . . . . . subtract 35 and simplify. a=6, b=5, c=-34

The quadratic formula tells you the values of x are ...

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-5\pm\sqrt{5^2-4(6)(-34)}}{2(6)}\\\\=\dfrac{-5\pm\sqrt{841}}{12}=\dfrac{-5\pm29}{12}\\\\\boxed{x=\left\{-\dfrac{17}{6},2\right\}}[/tex]

Tell whether the ordered pair (2, 6) is a solution of the system of linear equations. x+y=8 3x-y=0

**Answer:**

Yes, it is a solution.

**Step-by-step explanation:**

Plug in 2 into x and 6 into y, because 2 is the x value of the ordered pair and 6 is the y value of the ordered pair.

1st linear equation: 2+6=8, this is true.

2nd linear equation: 3x2-6=0, this is also true.

Therefore, since the ordered pair is a solution to both equations, it is a solution of the linear system.

The Yazoo Lands refers to areas on Georgias frontier. After the Revolutionary War, these were lands far from Georgia's mostly population, and much of it was located in what is now Alabama and . In order to protect the settlers that did live there, in Georgia Governor George Matthews signed the Yazoo Act, giving the government the authority to sell land to private companies at a very discounted price. However, these companies had very close ties to many in Georgia politics, so when they re-sold the lands a highly prices, many people suspected something illegal was going on. Furious Georgia voters caused many legislators to flee the state. When a new General Assembly met in , the Act was repealed, but later- in the Supreme Court ruled that the repeal of the law was unconstitutional. The Yazoo Land Fraud- as it became known- finally came to an end in 1814 when purchased the land.
