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%.
What is a percentage?
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%.

Bella wants to know how tall the oak tree in her back yard is, so she picks
a point that is 75 feet away from the base of the tree. She measures the
angle of elevation to be 40° from this point to the top of the tree. To the
nearest tenth of a foot, how tall is
A-89.4 feet
B-62.9 ft
C-48.2 ft
D-57.5 ft
Answer:
B = 62.9ft
Step-by-step explanation:
The distance where she is from the oak tree is 75ft,
The angle of elevation the stone makes with the top of the oak tree is 40°
The height of the tree is x ft
See attached document for better illustration
Using SOHCAHTOA,
Tanθ = opposite/ adjacent
θ = 40°
Opposite = x ft
Adjacent = 75ft
Tan40 = x / 75
X = 75 × tan40
X = 75 × 0.8390
X = 62.92ft
The height of the oak tree is 62.9ft

Answer: 19.95 x >89.95
Step-by-step explanation:
Hi, to answer this question we have to write an inequality using the information given:
The cost of each visit (x) is 19.95. That expression must be higher than the cost of the annual pass (89.95).
Mathematically speaking:
19.95 x >89.95

solve 2|x+1|=8
Answer:
x = 3 x = -5
Step-by-step explanation:
2|x+1|=8
Divide each side by 2
2/2|x+1|=8/2
|x+1| = 4
There are two solutions to an absolute value, one positive and one negative
x+1 = 4 x+1 = -4
Subtract 1 from each side
x+1 -1 = 4-1 x+1-1 = -4-1
x = 3 x = -5
Answer:
x=3 and -5
Step-by-step explanation:
to start with when you work with equations there will be two answers, no solution set or the answer will be 0. in this case there are two answers.
2/x+1/=8(first you remove all the things that are extra to the equation)
2 2
/x+1/=4 in this case it has two answers because 4 is greater than 0.
so you remove the bracket.
x+1=4 or x+1=-4
x=4-1 x=-4-1
x=3 x=-5

What is the value of y
Answer: y=54
Step-by-step explanation: since a triangles angles =180 and you just have this equation 180-72=2y that equals 108=2y
Answer:
The answer is B. 54 degrees.
Step-by-step explanation:
A triangle must be 180 degrees when all three angles are added together. 180 minus 72 is 108 degrees, which you have to divide by two, because there are two y values.
You can check this by adding 72 plus 54 plus 54 to get 180 degrees total.

nanette installed a security system in her office for $150. the monthly monitoring fee is $30. so far, nanette has spent $420 for her security system. for how many months has she had the service?
Answer:
9 months.
Step-by-step explanation:
Well we subtract the one time fee of $150 from $420
420-150=270
Now we need to divide $270 by $30, the price she pays every month.
270÷30=9
She has had the service for 9 months.

A local diner purchased a jukebox for 9400. The business makes a down payment of 1000 and agrees to pay 36 payments of 275 per month find the finance charge.
$10,900
$3,600
$1, 500
$8,400
Answer:
Option (3). $1500
Step-by-step explanation:
Cost price of the jukebox = $9400
Down payment made by the diner = $1000
Diner agreed to pay the rest amount by $275 per month for 36 months
Total amount to be paid by the diner = Down payment + monthly payments
= 1000 + 275×36
= 1000 + 9900
= $10900
Finance charge = 10900 - 9400
= $1500
Therefore, option (3). 1500 will be the answer.
If x+y−z=8 and x−y+z=12, then x=
Answer:
x = 10
Step-by-step explanation:
We see and show that x = 10
This makes y = 5 and z = 7 as 5-7 (y-z) = -2
As y5-z7 = -2 then we add 10 = 8
x+y-z = 10x-2yz = 8
x-y+z = 10 -5 +7 = 12 we know x = 10
We cna now prove.
x+y-z =8
x+5y-7z = 8
x +-2yz = 8
x = 8+2yz
x= 10
And prove
(x-5y)+7z= 12
x-y =12-7z
x = 5+5y
x=10
as x-5 (=5+7z) = 12
Have got the right answer here. Hope it helps.

Answer:
ok here you go
Step-by-step explanation:
i cant really plot them for you but i will help explain how to plot them.
the x-axis is the horizontal plane on the graph. the y-axis is the vertical plane on the graph. every coordinate has both a x and y point.
for you the x would be -8 and the y would be 7. first, you would go accross the x-axis to -8 and then go up to positive seven. you would be in the fourth quadrent in the graph. then you would do the same to the other pair. remember, (x,y)

The volume of a sphere with a radius of 5 cm is approximately _[blank]_ cm3.
Enter the value that correctly fills in the blank in the previous sentence.
Use 3.14 for π, and round your answer to the nearest hundredths place if necessary.
Answer: The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere (V) = 4/3 π radius³
Replacing with the values given and solving for V (volume)
V = 4/3 (3.14) 5³ = 4/3 (3.14) 125= 523.33 cubic centimeters
The volume of a sphere with a radius of 5 cm is approximately 523.33 cm3.

A line is described using the equation 2x + 3y = 6. The table lists the coordinates of two points on the line, the y-intercept and the x-intercept. Find the slope of this line.
A) The slope is 2.
B) The slope is 3.
C) The slope is −3/2
D) The slope is −2/3
Answer:
D)The slope is -2/3
Step-by-step explanation:
First, put this equation in slope-intercept form by subtracting 2x on both sides:
2x+3y=6
-2x. -2x
Your equation should be:3y=-2x+6
Then, divide the whole equation by 3 since y has to be by itself
3y=-2x+6
---- ------
3. 3
Your equation should be y=-2/3x+6
Since the slope in slope-intercept form is m in y=mx+b, -2/3×=m
Final answer:D) The slope is -2/3
