A tree grew from 6 feet to 12 feet in one year. What is the percent of change?
Answer:
100%
Step-by-step explanation:
It doubles in height, which makes it 100%
Answer:
100%
Step-by-step explanation:
The tree grew from 6 feet to 12 feet, which is a growth of 6 feet. 6 feet/6feet is 1, which in percent is 100%.
Now, you could say as the tree doubled in size, the change is 200%, however you must subtract the original height to gain the amount of change. So, 12-6 = 6, and 6/6 = 1, 1*100 = 100%.
2. AB – AD and BC - DC. Solve for x:
Answer:
From the diagram since AB = AD = BD, hence ABD is an equilateral triangle. (All angles = 60 degrees)
ADC is a straight line, hence BDC = 120 degrees and triangle BDC is an isosceles triangle.
Hence angle B = C and B+C = 180-120 = 60 degrees.
Hence, (x) angle C = A. 30 degrees

10 of the students in an algebra class passed an algebra test. If these students are 50% of all the students in the class, how many students are in this algebra class?
Answer:
Are 20 students in the class
Step-by-step explanation:
[tex]x(0.5) = 10 \\ x = \frac{10}{0.5} \\ x = 20[/tex]
Answer:
50% is a pretty simple number and a percentage almost everyone knows.
Since this is usually common knowledge we can say that 10 is equal to said 50%. We need to find out how many people there are in this class, and we can set up two separate equations of addition. 50%+50%=x
10+10=k
50+50%=100% which is the max amount of kids that there cna be in this classroom, and that there are. This means that the number which is equal to 50% plus itself will also equal 100% of the students.
10+10=20

Answer:
x=18, 4x=72, x=90
Step by-step explanation:
180 degrees = 90 degrees + x+ 4x
180 degrees = 90 +5x
180-90=5x
90=5x
x=18 degrees
right angle: 90 degrees
4x= 72 degrees

what is the value of x in the equation 4x + 1.3 = -7.9
Answer:
x = - 2.3Step-by-step explanation:
4x + 1.3 = -7.94x = -7.9 - 1.34x = -9.2x = -9.2/4x = - 2.3Answer:
[tex]4x + 1.3 = - 7.9 \\ 4x = - 1.3 - 7.9 \\ 4x = - 9.2 \\ x = \frac{-9.2}{4} \\ \boxed{x =- 2.3}[/tex]

Answer:
1)86
2)102
3)118
4)134
Step-by-step explanation:
1) so we know that the photographer started off with 86 photographs and has been uploading 16 each month since then
so in month 1 she would have 86
in month 2: 86+16=102
month 3: 102+16=118
month 4: 118+16=134
you could also use the expression
y=16x+70
how to get this equation: get slope(16) by subtracting p coords and m coord
substitute slope in slope intercept form
y=16x+b
insert in a coordinate pair(1,86)
86=16+b
b=70
hence y=16x+70
Bob swims 10 laps on even numbered dates. He swims 15 laps on odd number dates. How many laps has he completed by the sixth day of the month? PLEASE HELP

When multiplying the 2 and the -12 it would be -24, not 24. Which if my mental math is correct, would make the answer 6
Edit:
Note that subtracting a negative is the same as adding the absolute value.
so:
-24-(-30)
changes to
-24+30
and it equals
6

Jada saw a music video that her favorite artist recently posted online. The equation v (t) = 320 ⋅ 4t represents the number of views v of the video, t days since Jada saw the video. What does v (2) equal? (only enter number)
Answer:
2,560
Step-by-step explanation:
The equation v(2) is equal to 2560.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
v(t) = 320 x 4t ________(1)
v(t) represents the number of views v of the video, t days since Jada saw the video.
We see that,
v(t) is a function where t is the input and v(t) is the output.
Now,
Substitute t = 2 in (1)
v(t) = 320 x 4 x 2
= 320 x 8
= 2560
Thus,
The v(2) is equal to 2560.

Use the Rational Zeros Theorem to write a list of all potential rational zeros.
Answer:
1/5,2/5,4/5,1,2,4 B
Step-by-step explanation:
To my recollection the rational zeroes theorem is when you take all the factor of the Y intercept and list those and then take the factors from before and divide it by A
The first step would be to break down 4 into
1,2,4
Those are our first couple of answers, now it's time to divide it by 5
