Answer:
x = 15
Step-by-step explanation:
All angles add up to 180
so,
2x + 4x + 10 + 6x - 10 = 180
combine like terms
12x = 180
divide by 12
x = 15
check it by plugging it in
2x = 2(15) = 30
4x + 10 = 4(15) + 10 = 70
6x - 10 = 6(15) - 10 = 80
30 + 70 + 80 = 180

Find the length of CD.
PLEASE HELP quickkkk
Answer: see below
Step-by-step explanation:
Just apply Proportionality Theorem at correct time, with correct proportions, It tells, the ratio of two corresponding arms always equal.
So, 1) AB/BC = AJ/JI
2.5/2.25 = AJ/1.8
AJ = 2.5* 1.8 / 2.25
AJ = 2
2) BC/CD = JI / IH
2.25/CD = 1.8/1.2
CD = 2.25 * 1.2 / 1.8
CD = 1.5
3) CD/DE = IH/HG
1.5/3.5 = 1.2 / HG
HG = 1.2 * 3.5 / 1.5
HG = 2.8
4) For GF, we should use "Pythagoras Theorem"
h² = a² + b²
GF² = 6.5² - 6²
GF² = 42.25 - 36
GF = √6.25
GF = 2.5
5) Perimeter = 2.5 + 2.25 + 1.5 + 3.5 + 6.5 + 2.5 + 2.8 + 1.2 + 1.8 + 2
P = 26.55
6) Area = 1/2 * b * h
A = 1/2 * 9.65 * 10.3
A = 49.70

In a mixture of raisins and peanuts, 30% of the mixture is raisins and there 56 peanuts; how many raisins are in the mixture?
Answer: 24 raisins
Step-by-step explanation:
30% of the mixture are raisins which means that 70% are peanuts.
That 70% translates to 56 peanuts.
The total of the mixture is therefore:
= 56 / 70%
= 80 mixture of raisins and peanuts
Raisins are 30%:
= 30% * 80
= 24 raisins

So mike traveled 6 miles by taxi.
We know that the taxi driver chargers $3 per mile, so we say M is the mile variable, and for every M there is $3. So 3m+6 (initial fee) is the first part of the formula.
We set 3m+6=24 (24 being the total amount the taxi driver is charging)

find 21.4 of 855 percent equation
Answer:
21.4% of 855=182.97
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 855 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 855 is 100%, so we can write it down as 855=100%.
4. We know, that x is 21.4% of the output value, so we can write it down as x=21.4%.
5. Now we have two simple equations:
1) 855=100%
2) x=21.4%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
855/x=100%/21.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 21.4% of 855
855/x=100/21.4
(855/x)*x=(100/21.4)*x - we multiply both sides of the equation by x
855=4.67289719626*x - we divide both sides of the equation by (4.67289719626) to get x
855/4.67289719626=x
182.97=x
x=182.97
now we have:
21.4% of 855=182.97
Hope this helped :)

Isabel has just started a photo-sharing website and she is preparing for a presentation for an investor. Her site has 150 users and is growing by 25 users per day. Her competitor's site has 600 users and is growing by 10 users per day.
Answer: See Explanation
Step-by-step explanation:
Your question isn't well analysed but I guess that you want to calculate when both of them will have same number of users.
Let the number of days that both of them will have thesame number of competitors be x.
Therefore,
150 + 25x = 600 + 10x
25x - 10x = 600 - 150
15x = 450
x = 450/15
x = 30
They'll have same competitors by the 30th day.
The number of competitors will be:
= 150 + 25x
= 150 + 25(30)
= 150 + 750
= 900

A fast bi-level train travels from Washington, D.C. to Perryville Maryland. If this train traveled 75 miles in about .75 hours, what was the speed of the train
Answer:100 mph
Step-by-step explanation: it’s always distance divided by time. lol
The train travels to a distance of 75 miles in 0.75 hours, then the speed of the train will be equal to 100 miles per hour.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data mentioned in the question,
Distance (d) traveled by train = 75 miles
Time (t) taken by train to travel the distance = 0.75 hours
Then, use the equation of speed (s),
[tex]Speed =\frac{Distance}{Time}[/tex]
s = 75/0.75
s = 100 miles per hour.

Given the equation A=250(1.1)t, you can determine that the interest is compounded annually and the interest rate is 10%. Suppose the interest rate were to change to being compounded quarterly. Rewrite the equation to find the new interest rate that would keep A and P the same.
What is the approximate new interest rate?
Convert your answer to a percentage, round it to the nearest tenth, and enter it in the space provided, like this: 42.53%
Answer:
The new interest rate is about 0.1038.
As a percent, this is about 10.4%.
Step-by-step explanation:
We are given:
[tex]\displaystyle A=250(1.1)^t[/tex]
From this, we can determine that the interest rate is compounded annually at 10%.
We want a new equation that keeps A and P but the interest rate is compounded quarterly.
Compound interest is given by:
[tex]\displaystyle A=P(1+\frac{r}{n})^{nt}[/tex]
Since we are compounding quarterly, n = 4. Since the rate is 10%, r = 0.1. P stays at 250. Therefore:
[tex]\displaystyle A=250(1+\frac{0.1}{4})^{4t}[/tex]
Add:
[tex]\displaystyle A=250(1.025)^{4t}[/tex]
Rewrite:
[tex]A=250((1.025)^4)^t[/tex]
So:
[tex]A\approx 250(1.1038)^t[/tex]
Therefore, the approximate new interest rate is 1.1038 - 1 or about 0.1038.
As a percent, this will be 0.1038 or about 10.4%.

6. Solve for x in each of the following equations:
a. m(x + n) =n
b. x( a + b) = b(c - x)
c. mx = n(m + x)
Step-by-step explanation:
m(x + n) = n
mx + mn = n
mx = n - mn
x = (n - mn)/m
x(a + b) = b(c - x)
ax + bx = bc - bx
ax + bx + bx = bc
x(a + b + b) = bc
x(a + 2b) = bc
x = bc/(a + 2b)
mx = n(m + x)
mx = mn+ nx
mx - nx = mn
x(m - n) = mn
x = mn/(m-n)
