Answer:
A) 3w(w-7)
Step-by-step explanation:
[tex]\frac{w-5}{w-7} and \frac{w+8}{3w}[/tex]
w-7 is a binomial, and 3w is a monomial. Because you cannot put one denominator into the other or multiply both denominators by a number when you have this type of difference where multiplying by a number won't get you the same result, you must multiply them each other.
Therefore:
3w(w-7) would be your LCD.
Answer:
A. 3w (w − 7)Step-by-step explanation:
GivenFractions
(w- 5)/(w-7) and (w + 8)/3wTo findCommon denominatorSolutionWe observe that the fractions can't be simplified any more and they are in the simplest form
Next, the denominators w - 7 and 3w don't have common factors
Therefore the common denominator is the product of denominators:
3w(w - 7)Correct option is A
The distance traveled varies directly with the time spent in motion when speed is held constant.
If d represents the distance traveled and t represents time, which equation would represent this variation?
If you travel 150 miles in 4 hours, what is the constant of variation?
If you continue traveling at a constant speed, how long will it take to travel 200 miles? Round to the nearest tenth of
an hour.
about hours
Intro
Done
Answer:
16/3 or 5.3
Step-by-step explanation:
150 miles = 4 hours
Find how long it takes to travel 50 miles(GCF between 150 and 200)
150/3 = 4/3
50 miles = 1 1/3 hours: multiply by 4 to get 200 miles
50 x 4 = 4/3 x 4/1
200 = 16/3
16/3 hours or 5.3

Helppppp with angles
Answer:
61
Step-by-step explanation:
8 and 11 are corresponding angles. therefore they add up to 180.
so, 180-119 = 61
Answer:
61 degrees,
since 8=1 and 1=5, 5+11=180, 5=119 then 11 should equal 61

Lines x and y are parallel. Write an equation that represents the relationship between b and e. Explain how you know this equation is always true. Your explanation should use AT LEAST TWO of the following terms: vertical angles, corresponding angles, congruent, supplementary.
please help
Answer:
m∠b + m∠e = 180°
Step-by-step explanation:
Lines x and y are the parallel lines and a transversal line is intersecting these lines.
∠b ≅ ∠h [Vertical angles]
∠h ≅ ∠f [Corresponding angles]
Therefore, ∠b ≅ ∠f [Congruent angles]
m∠f + m∠e = 180° [Supplementary angles]
m∠b + m∠e = 180° [Since, ∠b ≅ ∠f]
Therefore, equation representing the relation between ∠b and ∠e is,
m∠b + m∠e = 180°
The required equation that represents the relationship between b and e is m<b + m<e = 180
From the given diagram, we can see that the line x and y are cut by a transversal. This shows that the following statements are true;
m<b and m<g are supplementary i.e m<b + m<g = 180
Also m<b and m<f are equal (alternate interior angle)
m<b = m<d (vertically opposite angle)
Also, since m<d and m<e are supplementary angles (angle on a straight line), then m<b and m<e are also supplementary
Hence the required equation that represents the relationship between b and e is m<b + m<e = 180

(11x-28)(7x-8) find x
After solving (11x-28)=(7x-8) the value of x is 5
Given:
(11x-28) = (7x-8)
11x - 28 - 7x + 8 = 0
(11x - 7x) - 28 + 8 = 0
4x - 28 + 8 = 0
4x - 20 = 0
4x = 20
Dividing by 4 on both sides we get,
4x/4 = 20/4
x = 20/4
x = 5
Therefore after solving (11x-28)=(7x-8) the value of x is 5.

What is the average rate of change of the line?
Answer:
- 12
Step-by-step explanation:
The slope of the line is a measure of the average rate of change
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 12(x + 4) ← is in point- slope form
with slope m = - 12 ← average rate of change

what is the slope of the line that passes through the points (7,-6) and (4,-6)? write your answer in simplest form
Answer:
m = 0, y = -6
Step-by-step explanation:
using point slope form :
[tex]y - y_{1} = m(x - x_{1})[/tex]
y-y1=m(x-x1) ; initial point (x1,y1) = (4,-6), final point (x,y) = (7,-6).
one substituted, it should look like this:

-6+6= m(7-4)
0 = m(7-4)
0 = 3m

Martina opens a savings account with an initial deposit and makes no other deposits or withdrawals. She earns interest on her initial deposit. The total amount of money in her savings account at the end of each year is represented by the sequence shown.
100, 105, 110.25, ...
Which recursive formula can be used to determine the total amount of money earned in any year based on the amount earned in the previous year?
A. f(n + 1) = f(n) + 5
B. f(n + 1) = 5f(n)
C. f(n + 1) = 1.05f(n)
D. f(n + 1) = 0.05f(n)
1.05 should be it
Step-by-step explanation:
In a recursive formula, each term of the sequence is found by using the previous term. In this case, the sequence is geometric because we are multiplying each term by the same constant, called a common ratio.
To find this common ratio, we find the percent of change between terms. We do this by using the formula
% change = (amount of change)/(original amount)
The amount of change between the first two terms is 105-100 = 5. This makes the percent change
5/100 = 0.05
The amount of change between the second two terms is 110.25-105 = 5.25. This makes the percent change
5.25/105 = 0.05
However, the common ratio in the sequence is not 0.05. This is because multiplying by this decimal would make the terms decrease instead of increasing. In this case, we are taking 100% of the number and adding an extra 5% (0.05 = 5%); this makes our common ratio 105% = 1.05.
This gives us the recursive formula

The members of a small town's local arts council are selling raffle tickets. The art council decides that the top three raffle ticket sellers will share a portion of the profits. The second-place seller will receive twice as much as the third-place seller. The first-place seller will receive $20 more than second-place seller. How much will each of the top three sellers receive if the profit portion they will share is $200?
Answer:
Profit shall be distributed as :
First seller = $92
Second seller = $72
Third seller = $36
Step-by-step explanation:
Let the first seller be A
Second seller be B
Third seller be C
Let the profit of third price seller C = "x"
Profit of B = 2x
Profit of A = 2x + $20
Total profit received by all of them = $200
$200 = (2x + $20) + (2x) + (x)
$200 = 5x + $20
$180 = 5x
x = $36
Therefore profit for 3rd seller = $36
Profit for second seller = $36 [tex]\times[/tex] 2 = $72
Profit for first seller = $72 + $20 = $92

A store sells a 33-pound bag of oranges for \$ 3.60$3.60 and a 55-pound bag of oranges for \$ 5.25$5.25. What is the difference between the price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges? The difference is \$$ per pound.
Answer:
$0.014
Step-by-step explanation:
Given that :
Sales price of 33-pound bag of oranges = $3.60
Sales price of 55-pound bag of oranges = $5.25
Price per pound of 33-pound bag:
Sales price / number of pounds
= $3.60 / 33
= $0.109 per pound
Price per pound of 55-pound bag:
Sales price / number of pounds
= $5.25 / 55
= $0.095 per pound
Difference in price per pound of 33-pound bag and 55-pound bag of oranges :
$0.109 - $0.095
= $0.014

Answer:
a(t) = 487(1/2)^(t/36)a(5) = 442.302 kgStep-by-step explanation:
The exponential function for half-life problems is easily written using 1/2 as the base of the exponent.
present value = (initial value) × (1/2)^(t/(half-life))
Then the amount (a) remaining after t days is ...
a(t) = 487 × (1/2)^(t/36)
__
After 5 days, the amount remaining is ...
a(5) = 487×(1/2)^(5/36) ≈ 442.302 kg
_____
Some folks like their exponential function to be written using e as the base for the exponent. Here, that would be ...
a(t) = 487·e^(-0.019254t)
where the constant in the exponent is -ln(2)/36.
