Answer:

69.84%

Step-by-step explanation:

percentage increase

[tex]\frac{107-63}{63} \times 100\\=\frac{44}{63} \times 100\\=\frac{4400}{63} \\=69.84/%[/tex]

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The percentage increase in the height of the tree is 69.84%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Height of the tree = 63 inches.

Height after several years = 107 inches.

Now,

The percentage increase in the height of the tree.

= (107 - 63)/63 x 100

= 44/63 x 100

= 69.84%

Thus,

The percentage increase in the height of the tree is 69.84%.

a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.

Answer:

It will take 7 hours for car B to catch up to Car A.

Step-by-step explanation:

So if you write the the two equations out:

[tex]Car A=70x\\Car B= 90x-140[/tex]

You'll want to assume that x is how many hours and y is how many km.

The reason car B has, -140, is because car A is in front of it by two hours and in those two hours it reached 140km. Meaning that Car B is starting at 140 km behind Car A.

If you graph these two equations out you'll realize that they intersect at the point (7, 490). Meaning that Car B caught up with Car A after 7 hours and both cars had traveled 490km.

Tangent is opposite over adjacent

tan(68)= GI/2

GI= 2tan(68)

The expression has a value that is 6 times the value of the expression 63 – 3y would be, 6 × (63 - 3y)

The correct answer is option (D)

"An expression is a sentence with a minimum of two numbers and at least one mathematical operation in it."

For given example,

We need to find the value that is 6 times the expression 63 – 3y.

If we write it as an expression then it would be,

6 × (63 - 3y)

Answer:sorry i need points for my test

Step-by-step explanation:

Answer:

35 to 44 is the error interval

The possible integer values of n are:

-1, 0, 1 , 2 , and 3.

-1 to 3 are all greater than -2.

3 is the maximum since 3 is the greatest number where n is equal to it or lesser than it.

Solving the inequality: 3y - 4 > 17

3y - 4 > 17

Add 4 to both sides to move it.

3y > 17 + 4

3y > 21

Divide both sides by 3 to get the value of y.

3y/3 > 21

y > 7

The sign does not change since we did not divide or multiply by a negative.

Therefore, y is greater than 7.

Answer:

[tex]n \in \mathbb{Z}[/tex]

Inequality given:

[tex]-2 < n \leq 3[/tex]

Interval notation: [tex](-2, 3][/tex]

[tex]\{n \in \mathbb{Z}| -2<n\leq 3 \}[/tex]

Writing down the values of [tex]n[/tex]

The set (N) for possible values of [tex]n[/tex] is:

[tex]N=\{-1, 0, 1, 2, 3\}[/tex]

Now, solving the inequality [tex]3y - 4 > 17[/tex]

[tex]3y - 4 > 17\\3y-4+4>17+4\\3y>21\\y>7[/tex]

Interval notation: [tex](7, \infty)[/tex]

[tex]\{n \in \mathbb{R}| y>7 \}[/tex]

Answer:

Ok so first you would have to turn them into improper fractions which is

3 [tex]\frac{1}{2\\}[/tex] = [tex]\frac{7}{2}[/tex] and 4 [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{5}[/tex]

So now that you have made them both improper fractions you have to find common denominators.

To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take [tex]\frac{22}{5}[/tex] and mutiply both numbers by 2 and get [tex]\frac{44}{10}[/tex]. Then mutiply both numbers in [tex]\frac{7}{2}[/tex] by 5 to get a common denominator.

[tex]\frac{35}{10}[/tex]

[tex]\frac{35}{10} -[/tex] [tex]\frac{44}{10}[/tex] =35 - 44 = -9 so your answer is [tex]-\frac{9}{10}[/tex]

I just finished the assignment

Answer:

1.  3

2. A

Step-by-step explanation:

1. (-3+3)^2 + (2 + 1)^2 - r^2 = 0

0 + 9 - r^2 = 0

r^2 = 9

r = 3

2. 2x^2 + 4x + 2y^2 + 12y = - 6

Divide by 2.

(x^2 + 2x) + (y + 6y) = -3

Remember how to complete the square..

(b/2)^2

So...

(2/2) ^ 2 = 1

(6/2) ^ 2 = 9

(x^2 + 2x + 1) + (y^2 + 6y + 9) = -3 + 1 + 9 <--- You must remember to add whatever you add on the left to the right!

Now.. rewrite in standard form..  

(x+1)^2 + (y+3)^2 = 7

Careful!! the circle equation is written as

(x - h)^2 + (y - h)^2 = r^2

Meaning that the radius is square root of 7. At center (-1, -3)
