Answer:
Yes
Step-by-step explanation:
Yes, since the relationship between the denominators can be expressed as x(4) = y, then you must apply this to the numerators as well. If you multiply 2 by 4 the result is 8, which aligns with the 2nd ratio - in fraction form.

Answer:
Yes
Step-by-step explanation:
2/3 and 8/12 are equal because of a multiplying factor. To get from 2 to 8, you'd have to multiply by 4. And to get from 3 to 12 you would have to multiply by 4 as well. So that means they are equal because both the numerator and denominator are multiplied by 4.
Sketch a figure that is similar to this figure. Label side and angle measures.
Step-by-step explanation:
Similar figures have different side lengths but corresponding angles are congruent.
The figure you sketch will have side length:
s = 12k, where k is the scale factorWhen k > 1, you sketch a larger figure, when 0 < k < 1, you sketch a smaller figure than pictured.
See attached, the two figures, one has side of 18 when k = 1.5, another one has side of 6, when k = 0.5

The graph of F(x), shown below, resembles the graph of G(x) = x2, but it has
been changed somewhat. Which of the following could be the equation of
F(x)?
Answer:F(x)=-x2-3
Step-by-step explanation:We are given a function:
The graph of is also shown in the given question figure.
It is a parabola with vertex at (0,0).
Sign of is positive, that is why the parabola opens up.
General equation of parabola is given as:
Here, in G(x), a = 1
Vertex (h,k) is (0,0).
As seen from the question figure,
The graph of F(x) opens down that is why it will have:
Sign of as negative. i.e.
And vertex is at (0,-3)
Putting the values of a and vertex coordinates,
Hence, the equation of parabola will become:

Suppose that you could replace the ordered pair (1, 4) to make the relation R (shown left) into a function. Which ordered pair would work? (1, 2) (â€"1, 4) (2, 3) (4, 15).
We want to see which ordered pair we can add to the one we have in order to make R a function (sadly, we do not have the relation R, so expect a general answer).
Let's start by defining a function.
A function is a relation that maps elements from one set, the domain, into elements of another set, the range.
Where we also have a rule, each element in the domain can be mapped into only one element in the range.
So for example, if our relationship is:
R { (1, 2), (1, 3), (2, 4)}
The element of the domain "1" is being mapped into two different elements of the range, then this is not a function.
So, to answer the question, you would want to replace the element (1, 4) from one element that does not share the first value with any other of the relation.
Just to given an example, if the relation is:
R : { (1, 1), (1, 4), (2, 3), (3, 6)}
From the options, the only one that does not share the first element with any of the ordered pairs in R is (4, 15)
Then we replace (1, 4) by (4, 15)
And the relation becomes:
R' : {(1, 1), (2, 3), (3, 6), (4, 15)}
Which is a function.

Answer:
c = 55
Step-by-step explanation:
I would solve this by cross multiplying, but some teachers don't appreciate you skipping a step like that. Instead:
[tex]\frac{5}{2} =\frac{c}{22}[/tex]
First, multiply both sides by 2:
[tex]5=\frac{2c}{22}[/tex]
Then, multiply both sides by 22:
[tex]2c=110[/tex]
Now, just solve for c by dividing both sides by 2:
[tex]c=55[/tex]
Answer:
C = 55
Step-by-step explanation:
To figure out c you must first isolate c so there shouldn't be any other numbers or signs (addition, subtraction, division, and multiplication) on the same side of the equal sign as variable C.
The inverse of dividing 22 is multiplying 22 on both sides of the equation.
You would get 22/1 * 5/2 = C. 22 * 5 is 110 and 1 * 2 is still 2 so 110/2 = C.
Enter 110/2 into the calculator and you would get C = 55

If a town with a population of 10000 doubles in size every 43 years, what will the population be 86 years from now
Answer:This is an exponential growth problem. If the population doubles periodically, it follows a law like this:
P(t) = P(0)ekt
where P(0) is the initial population at time t=0, and k is a constant with units of years-1.
To find k, let t=0. Then P(t) = P(0) = initial population = 5000.
Since the population doubles every 12 years, we can write
P(t+12) = 2P(t)
P(0)ek(t+12) = 2[P(0)ekt]
Simplifying,
e12k = 2
k = ln(2) / 12 = 0.0577623 years-1
Finally,
P(t) = 5000e0.0577623t, t in years
Then at t=48 years from now,
P(48) = 5000e(0.0577623 * 48) = 80,000

-3w+15w+7=8w+43 what does w equal?
Answer:
w = 9
Step-by-step explanation:
- 3w + 15w + 7 = 8w + 43 , simplifying
12w + 7 = 8w + 43 ( subtract 8w from both sides )
4w + 7 = 43 ( subtract 7 from both sides )
4w = 36 ( divide both sides by 4 )
w = 9
W=9
first, you simplify the expression.
12w + 7 = 8w + 43.
After that, we group all the w terms on the left side of the equation.
Subtract 8w from both sides:
12w + 7 - 8w = 8w + 43 - 8w
Group like terms:
12w - 8w + 7 = 8w + 43 - 8w
Simplify the arithmetic:
4w + 7 = 8w + 43 - 8w
Group like terms:
4w + 7 = 8w - 8w + 43
Simplify the arithmetic:
4w + 7 =43
Then, we group all constants on the right side of the equation
Subtract 7 from both sides:
4w + 7 - 7 = 43 - 7
Simplify the arithmetic:
4w = 43 - 7
4w = 36
Now, we isolate the w. Divide both sides by4:
4w / 4 = 36 / 4
Simplify the fraction:
w = 36/4
Find the greatest common factor of the numerator and denominator:
w = 9 × 4/1 × 4
Factor out and cancel the greatest common factor:
w = 9

Rosa put an “blank” cream on the cut on her finger to keep germs out of it
1- interlocking
2-antimedicine
3-antiseptic
4- interrelated
Rosa put an antiseptic cream on the cut on her finger to keep germs out of it.
An antiseptic is a substance that prevents the growth and development of microorganisms, such as bacteria, on living tissues.
When Rosa applied antiseptic cream to her cut finger, she aimed to create an environment hostile to germs. This action helps prevent infections and promotes the healing process.
The term antiseptic is derived from the Greek words "anti," meaning against, and septikos, meaning putrefying. Antiseptics are commonly used for cleaning wounds, disinfecting surfaces, and maintaining personal hygiene. They are milder than disinfectants, which are typically used on inanimate objects.
Rosa's choice of an antiseptic cream demonstrates her understanding of the importance of wound care. The cream likely contained substances that inhibit bacterial growth, such as hydrogen peroxide or iodine. By applying the antiseptic cream, Rosa effectively created a barrier against potential infections. It's crucial to clean and treat cuts promptly, as untreated wounds can lead to more severe health issues.
In summary, the use of an antiseptic cream by Rosa showcases her responsible approach to wound care. Antiseptics play a vital role in preventing infections and supporting the body's natural healing process. By applying an antiseptic cream, Rosa took a proactive step in safeguarding her health and ensuring the well-being of her injured finger.

i just need this last question Milan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $49.96 and costs an additional $0.15 per mile driven. The second plan has an initial fee of $57.96 and costs an additional $0.13 per mile driven. How many miles would Milan need to drive for the two plans to cost the same?
Answer:
400 miles
Step-by-step explanation:
Let the total cost of a plan be $T and the number of miles driven be m.
First plan
T= 0.15m +49.96 -----(1)
Second plan
T= 0.13m +57.96 -----(2)
When the two plans cost the same, the value of T in the first plan is equal to that of the second plan.
Equating (1) and (2) together:
0.15m +49.96= 0.13m +57.96
0.15m -0.13m= 57.96 -49.96
0.02m= 8
m= 8 ÷0.02
m= 400
∴ Milan would need to drive 400 miles for the two plans to cost the same.
