PLZ HELP here are three triangles shown separately, these triangles are similar. How do you know?
Answers
Answer:
Using the AA similarity postulate, you can determine that these triangles are similar.
Step-by-step explanation:
All three triangles are right triangles, so they all have 90° angles.
Angle B is present in the large and small triangle. Therefore, you know those 2 triangles are similar. You can also prove that angles A and C are the same.
A and B are complementary angles in the large triangle and the same with B and C in the small one. Since B ≅ B by Reflexive Property, A and C must have the same angle measurement since they are complements of the same angle.
Answer: Becasue the AA similarity Postulate

At the store you want to buy a bunch of 3d printed Christmas gifts for your family. Each large tree costs $4.50 , and each small tree costs $2.25, If you buy 4 large trees, and can spend a total of $50. Write and solve an inequality for number of small trees (s) you can buy
Answers
We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.
If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.
The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.
To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:
s * $2.25 = $32
s = $32 / $2.25
s = 14.22
Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.
Answer:
If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

Step-by-step explanation:
Formula:

V=3×4×2=24 units³
Answer:
the answer should be 24 units^3 because the formula for finding volume is V= lwh so we need to multiply 2 times 3 and 4 and when we do that we get an answer of 24 so a is the correct answer and have a great day.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Step-by-step explanation:
If the diameter is doubled, the circumference is doubled. It is shown here:
18 * 3.14 = 56.52
36 (doubled diameter) * 3.14 = 113.04
If the circumference with the doubled diameter divided by the circumference of the original diameter comes out as 2, then it is proven that doubling the diameter doubles the circumference.
113.04/56.52 = 2.
The image for the rest is attached.
Answer:
Step-by-step explanation:
The Radius is (1/2) of the diameter, so to get the diameter we will multiply the radius by 2.
1. 9*2=18in
The we multiply the diameter by \(\pi\) to get the cicumference. We know to do this because the equation of the circumference is C=\(\pi\)d or C=2\(\pi\)r. (p.s \(\pi\)=3.1415926)
2. 18in*(3.1415926)=56.5487in
3. If the diameter is doubled the circumference is also doubled. We know this because of the equation C=\(\pi\)d. The circumference is dependant upon the diameter and grows (or shrinks) with it.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation

When I round 6396 to 3 significant figures, I get 6400. I was double checking my work and used scientific notation for 6400, which is 6.4*10³, but when I counted the significant figures in scientific notation, I only get 2, which are 6 and 4, but there were supposed to be 3. Anyone can help to explain?
Answers
This is one slight annoyance when it comes to sig figs, in my opinion anyway. You did the steps correct. The 639 bumps up to 640, so 6396 rounds to 6400 when rounding to 3 sig figs.
Normally the trailing zeros, ie zeros on the right, are not significant. So 6400 shows only 2 sig figs. What we need to do is draw a horizontal line over the first zero to show that it is significant (while the other zero is not significant)
So you'll write it like this \(64\overline{0}0\)
This notation can be problematic when it comes to decimals because it could be easily mixed up with the repeating decimal notation.
When you convert \(64\overline{0}0\) to scientific notation, you would get \(6.40 \times 10^3\).
In short: \(64\overline{0}0 = 6.40 \times 10^3\)
Here the zero is significant because the zero is present in the scientific notation result. Writing \(6.4 \times 10^3\) shows 2 sig figs while \(6.40 \times 10^3\) has 3 sig figs.
It's similar to how the number \(5.7\) has 2 sig figs while \(5.70\) has 3 sig figs. While the zero is trailing, having it after a decimal point indicates to the reader that you achieved this level of accuracy.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.
Solve the equation r = 1/(x-1) for x in terms of r. In other words, manipulate the equation until you have x equal to an expression with r's in it but no x's.
Answers
Answer:
\(x=\frac{1}{r} +1\)
Step-by-step explanation:
\(r=\frac{1}{x-1}\)
\(r(x-1)=1\)
\(x-1=\frac{1}{r}\)
\(x=\frac{1}{r} +1\)
Answer:
\(x=\dfrac{1+r}{r}\)
Step-by-step explanation:
Given equation:
\(r=\dfrac{1}{(x-1)}\)
Multiply both sides by (x - 1):
\(\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)\)
\(\implies r(x-1)=1\)
Expand the brackets:
\(\implies rx-r=1\)
Add r to both sides:
\(\implies rx-r+r=1+r\)
\(\implies rx=1+r\)
Divide both sides by r:
\(\implies \dfrac{rx}{r}=\dfrac{1+r}{r}\)
\(\implies x=\dfrac{1+r}{r}\)

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.
