Answer:
w = [tex]\frac{P-2h}{2}[/tex]
Step-by-step explanation:
Given
P = 2w + 2h ( subtract 2h from both sides )
P - 2h = 2w ( divide both sides by 2 )
[tex]\frac{P-2h}{2}[/tex] = w

State if the triangles in each pair are similar. Remember a) AA/SAS/SSS
b) prove it. C) write a similarity statement.
Answers
Note how we have a segment that is also 4 units long in the other triangle; however, we won't use that one just yet. Instead, we'll go for the 2 unit segment. As it turns out, every piece of the triangle on the right side is half that of the left side triangle.
Segment ED is 2 units long. So AB and ED pair up
------------------------------
BC is 8 units long; DF is 4 units long (half of BC). So BC and DF pair up
I started at A, went to B, then to C in that exact order marking the side lengths of 4 and 8 respectively. At the same time for the other triangle, I started at E, moved to D, then to F recording the side lengths 2 and 4
So A pairs up with E, B pairs with D, and C pairs with F
Therefore, triangle ABC is similar to triangle EDF. The order is very important so that the points line up and correspond in the proper manner.
I used the SSS (side side side) similarity theorem to prove the triangles similar. This theorem says that if the sides are in proportion to one another, then the triangles are similar.

A kind teacher gives you 20 cents for every question you get right, but you have to pay the
teacher 10 cents for every question you get wrong. After 30 questions you have made a
profit of $1.80.
a ) Form an equation with x representing the number of questions you got right.
b )Solve your equation to find how many questions you got right.
Answers
Answer:
Let n be the number of questions you got right. Then
30-n equals the number of questions you got wrong.
So:
A) 20n-10(30-n)=180
30n-300=180
30n=480
n=16
30-n=14
B)You got 16 questions right and 14 questions wrong.
split 50 into the ratio 9:1 what is the answer
Answers
Answer:
46
Step-by-step explanation:
The numbers 45 and 5, in the ratio of 9:1, when added together, sum up to 50.
To split the number 50 into a specific ratio, 9:1. This means we need to divide 50 into two parts, where one part is nine times larger than the other part.
To split 50 into the ratio 9:1, we need to divide the number 50 into two parts, let's call them "x" and "y." The ratio 9:1 tells us that one part is nine times larger than the other. So, we can express this relationship mathematically as:
x = 9y
Now, we know that the sum of the two parts, x and y, should add up to 50:
x + y = 50
Since we have an expression for "x" in terms of "y," we can substitute it into the second equation:
9y + y = 50
Now, let's combine the y terms:
10y = 50
Next, we isolate "y" by dividing both sides of the equation by 10:
y = 50 / 10
y = 5
Now that we've found the value of "y," we can use it to find "x" using the first equation:
x = 9 * 5
x = 45
So, the two parts are x = 45 and y = 5. We can verify that the ratio is indeed 9:1:
x / y = 45 / 5 = 9
And the sum of the two parts is:
45 + 5 = 50
The numbers 45 and 5, in the ratio of 9:1, when added together, sum up to 50.
In summary, to divide 50 into the ratio 9:1, we found that one part (x) is 45, and the other part (y) is 5. This satisfies the condition that one part is nine times larger than the other, and their sum is 50.

1. C(t) =240(0.083)^24t
2. C(t)=10(.083)^t
3. C(t)=10(1.986)^t
4. C(t)= 240(1.986)^t/24

Given:
The function is:
[tex]C(t)=10(1.029)^{24t}[/tex]
Where, C(t) is the total number of cells after t hours.
To find:
The function that is approximately equivalent to C(t).
Solution:
We have,
[tex]C(t)=10(1.029)^{24t}[/tex]
It can be rewritten as:
[tex]C(t)=10(1.029^{24})^{t}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]C(t)\approx 10(1.986)^{t}[/tex] [tex][\because 1.029^{24}\approx 1.986][/tex]
The function [tex]C(t)=10(1.986)^{t}[/tex] is approximately equivalent to C(t).
Therefore, the correct option is 3.

Find an equation of variation in which y varies directly as x and y = 60 when x = 0.4. Then find the value of y when x = 2
Answers
Answer:
y = 300
Step-by-step explanation:
The equation of variation in which y varies directly as x is written Mathematically as:
y ∝ x
y = k × x
y = kx
Where k = Proportionality Constant
We find k
a) y = 60 when x = 0.4.
60 = 0.4 × k
k = 60/0.4
k = 150
b) find the value of y when x = 2
y = kx
k = 150
Hence,
y = 150 × 2
y = 300
