Answer:
Of course the percentage is an increase. If it moves from 50ft to 190 ft its an increase. So you can automatically cross out “c” and “d”.
Now just think about it logically. This can save you from a lot of work.
So you have it from 50ft to 190 ft.
Use 100% place holders.
50ft*100 percent is 50
50ft*200 percent is 150
Now your somewhere close near the 190 ft range.
THink about the last two options, you can ignore the 200 percent since thats what we used as the closest possible place holder.
Now use 50% place holders.
50% of 50 is 25.
so 175 is the closest we can get with 250%
Now we still have about a 15 ft space.
250% is obviously greater then 238% so we can elimate that option.
The final answer is (B)
Step-by-step explanation:
If wanted proof
So we discussed this logically but if you want it mathematically below is the explanation:
50ft to 190 ft.
To calculate percentage of change you want to first find the distance.
190-50=140
Theres a 140 ft change.
Now you can use proportions
50/1 = 140/x
The 50/1 represents 50 feet for 100 percent or 1
The 140 represents 140 feet for (x) feet since its unknown
now cross multiply
50*x
140*1
50x=140
Now solve
140/50=2.8
2.8 is the deciaml If you convert it to a percentage you just multiply it by a hundred since percent means out of a hundred.
2.8 out of a hundred it 280%

What number is 12 more than 1/3 of itself?
Answer:
18
Step-by-step explanation:
Let the number be x.
1/3 of itself is 1/3 x or x/3.
x = x/3 + 12
3x/3 - x/3 = 12
2x/3 = 12
3/2 * 2x/3 = 3/2 * 12
x = 18
Answer: 18
The equation is formed as x - x/3 = 12. Then the solution of the equation will be 18.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The number is 12 more than 1/3 of itself.
Let the number be 'x'. Then the equation is written as,
x = x/3 + 12
Simplify the equation, then the value of 'x' will be calculated as,
x - x/3 = 12
3x - x = 36
2x = 36
x = 36/2
x = 18
The equation is formed as x - x/3 = 12. Then the solution of the equation will be 18.

What is the logarithmic formula 10000= 625/8*2^t ?
9514 1404 393
Answer:
log(128) = t·log(2)
Step-by-step explanation:
You can take logarithms the way the formula is, or you can simplify it first.
As is
log(10000) = log(625) -log(8) +t·log(2)
__
Simplified
8·10000/625 = 2^t . . . . . multiply by 8/625
128 = 2^t
log(128) = t·log(2)
_____
Solution:
t = log(128)/log(2) = 7

Step-by-step explanation:
How many you know that the expression is a perfect square trinomial pa help please
Multiply the roots of the first and third terms together. Compare to the middle terms with the result in step two. If the first and last terms are perfect squares, and the middle term's coefficient is twice the product of the square roots of the first and last terms, then the expression is a perfect square trinomial.
What is an equivalent ratio of 5:9
Step-by-step explanation:
There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.
For example
10:18,
15:27
Hope this helps.
Answer:
10:18
Step-by-step explanation:
Anything really just times both sides by the same number.
For example to get to 10:18 I multiplied both sides of 5:9 by 2.
If you were to multiply 5:9 by 3 (which would 15: 27) it would still be an equivalent to 5:9.
MONEY PRIZE FOR THE FIRST PERSON TO GET THIS RIGHT AT THE END OF THE PROBLEM LIST METHOD OF ONLINE PAYMENT YOU WANT!
Situation: You love to knit sweaters and you want to start a small business to make money from your talent. You want to do the math first to find out how long it will take for you to make a profit. You must pay a fixed fee of $90.00 to start the company up plus $15.00 for each sweater to pay for the yarn. You want to charge $30.00 for each sweater that you sell.
1. Write an equation for the cost of the company
Choose and define your variables in words:
x:
Equation: y:
2. Write an equation for the money made, INCOME (NOT PROFIT ALL INCOME), selling sweaters
Choose and define your variables in words:
x:
Equation: y:
After you have your equations:
-Find the cost and income when you sell 2 sweaters. (You should have two different answers because you had two different equations one for the INCOME and one for the COST!)
Hints: REMEMBER X is your independent variable so look at the independent number or thing about the problem and write it for x: . Also REMEMBER Y is your dependent variable so whatever your x is y will depend on it if X changes Y also changes look at the problem and ask yourself "What has an effect on what? and "What is effected by what?" This will help you answer the problem.
Answer:
1. y = 90x
x: the amount of companies to start
y: The total amount it will cost.
2. y = 30x
y: the total income
x: the amount of sweaters being sold.
The answer to the last question(I think would be):
cost: $30
income: $60
as:
equation to find cost = y = -15x
equation to find income = y = 30x

Find the area of a rectangular garden plot that measures 21 ft by 25.2 ft. Report with the correct number of significant digits.
The area of a shape is the amount of space it occupies.
The area of the garden is 529.2 square feet
The given parameters are:
Shape: Rectangle
Dimension: 21ft by 25.2ft
The area of a rectangle is:
[tex]\mathbf{Area = Length \times Width}[/tex]
So, we have:
[tex]\mathbf{Area = 21 \times 25.2}[/tex]
[tex]\mathbf{Area = 529.2}[/tex]

Solve the simultaneous equations.
x + 2y = 9
5x – y = – 10
Answer:
(- 1, 5 )
Step-by-step explanation:
Given the 2 equations
x + 2y = 9 → (1)
5x - y = - 10 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
10x - 2y = - 20 → (3)
Add (1) and (3) term by term to eliminate y
11x + 0 = - 11
11x = - 11 ( divide both sides by 11 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
- 1 + 2y = 9 ( add 1 to both sides )
2y = 10 ( divide both sides by 2 )
y = 5
solution is (- 1, 5 )
x + 2y = 9 x + 2y = 9
=====》
5x - y = - 10 (×2) 10x - 2y = - 20
+____________
11x + 0 = - 11
11x = - 11
x = - 1
Thus :
- 1 + 2y = 9
Add both sides 1
2y - 1 + 1 = 9 + 1
2y = 10
Divide both sides by 2
2y ÷ 2 = 10 ÷ 2
y = 5
