The first triangle is dilated to form the second triangle. What is the scale factor? Please show your math work step by step.
Answers
Answer:
2.5 is the scale factor
Step-by-step explanation:
Skills needed: Identifying the Scale Factor, Division
1) First, we need to understand what the scale factor is.
A scale factor is the value being multiplied by one side of a figure to form another figure that is bigger or smaller. For example:
Let's say you are given a triangle with side lengths 3 cm, 4 cm, and 5 cm and you are supposed to find the side lengths of a new triangle when the scale factor being used is 2. Here, you would multiply all the sides by the value 2. So, the 3 sides are:3 x 2, 4 x 2, and 5 x 2 ---> 6 cm, 8 cm, 10 cm.
2) So to find the scale factor in a problem, you would do the side of one triangle divided the corresponding side of the other triangle.
So to find the scale factor in the above problem (if we were only given side lengths 3 cm, 4 cm, and 5cm & also 6 cm, 8 cm, and 10 cm), you would do:
[tex]\frac{6}{3}[/tex] or [tex]\frac{8}{4}[/tex] or [tex]\frac{10}{5}[/tex], all of which equal 2.
3) So in this problem, you would simply do [tex]\frac{10}{4}[/tex], since 10 and 4 are corresponding sides of dilated triangles.
This is [tex]\frac{5}{2}[/tex] when simplified, or 2.5 as a decimal, since scale factors are usually expressed as decimals.
Hope this helps and have a nice day!! :) :] :D

Step-by-step explanation:
Hello There!
The shown angles have a sum of 90 degrees
This is noticeable because there is a square at the vertex which indicates that its a right angle
A right angle has a measure of 90 degrees
That being said we can create an equation to solve for x
90 = 66 + 8x having made an equation we now solve for x
step 1 subtract 66 from each side
90 - 66 = 24
66 - 66 cancels out
now we have
24 = 8x
step 2 divide each side by 8
8x/8=x
24/8=3
we're left with x = 3
Answer:
x=3
Step-by-step explanation:
8x+66=90 complement
8x=90-66
x=24/8=3

2x is less than 8 or B
Step-by-step explanation:
When looking at the number line you got to look to see if the circle is closed or not. In this case it is a closed circle meaning to include the number. Then look at what direction it is going toward. Is it increasing? Is it decreasing? In this case it is decreasing. Meaning that 2x is less than 8

The graph below shows a company's profit f(x), in dollars, depending on the price of goods x, in dollars, being sold by the
company:
Part A: What do the x-intercepts and maximum value of the graph represent?
prefent? ?
Part B: What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and
profit?
Part C: What is an approximate average rate of change of the graph from x = 1 to x = 3, and what does this rate represent?
Answers
The x intercepts are the prices that profit equals zero
B
Increasing from - infinity to 3 and decreasing from 3 to infinity. When price is less than 3 every increase in price results in an increase in profit. When price is greater than 3, every increase in price results in a decrease in profit. So what this is saying about sales is that when you set the price beyond 3 bucks, the amount of people willing the buy at that price drops such that you start making LESS profit because less people are willing to buy, and the lack of buyers offsets the additional price that the others are paying.
C
The average rate of change is 60 and this represents the increase in profit per increase in price
1÷2(2x+6)=4x-1
solve pls no links!!!
Answers
Answer:
Step-by-step explanation:
1 ÷ 2(2x+6) = 4x-1
[tex]\frac{1}{2(2x + 6)} = 4x -1[/tex]
[tex]\frac{1}{2*2x+2*6 } = 4x - 1 \\\\\frac{1}{4x + 12} = 4x - 1\\[/tex]
1 = (4x - 1)(4x + 12)
Use FOIL method.
1 = 4x * 4x + 4x *12 - 1 * 4x - 1*12
1 = 16x² + 48x - 4x - 12
1 = 16x² + 44x -12
0 = 16x² + 44x - 12 -1
16x² + 44x - 13 = 0

The two quads are of similar, and we know that they are of ratio 1:2, thus
3y+5/7 = 2
y = 3
Answer:
y = 3
Step-by-step explanation:
The figures are similar so the ratios of corresponding sides are equal, that is
[tex]\frac{UR}{DA}[/tex] = [tex]\frac{TS}{CB}[/tex] , substitute values
[tex]\frac{4}{2}[/tex] = [tex]\frac{3y+5}{7}[/tex] ( cross- multiply )
2(3y + 5) = 28 ( divide both sides by 2 )
3y + 5 = 14 ( subtract 5 from both sides )
3y = 9 ( divide both sides by 3 )
y = 3

The percentage change (an increase) wa 40%.
Step-by-step explanation:
The beginning number of acres was 100; adding 40 more brought that to 140 acres. This was an increase. Dividing the increase (40) by the starting value (100) yields 0.40. Finally, multiplying this result by 100% yields 40%.

Answers
Answer:
£290.70
Step-by-step explanation:
Number of notes of $50 = 5
Total value = 50 × 5 = $250
Number of notes of $20 = 2
Total value = 20 × 2 = $40
Number of notes of $10 = 7
Total value = 10 × 7 = $70
Number of notes of $5 = 3
Total value = 5 × 3 = $15
Total value of all notes with John = 250 + 40 + 70 + 15
= $375
Since, $1.29 = £1
Therefore, $1 = £[tex]\frac{1}{1.29}[/tex]
Therefore, $375 = £ [tex]\frac{375}{1.29}[/tex]
= £290.70
