Answer:
x=7/3
Step-by-step explanation:
AB/XY=BC/YZ
The length of {x} is equivalent to 7/3 units.
What is scale factor? How it is used in Dilating sides?Scale factor tells us by how much one quantity is greater than the other. It is denoted by K. Mathematically -
K = a/b.
Rewriting, we get -
a = Kb
If a side length [a] of any 2 - D figure is dilated by a scale factor of [k], then the length of new side will be [Ka].
Given is that ABC is similar to XYZ.
Since, the two triangles are similar, than their corresponding sides will be proportional to each other. This means that the ratio of corresponding sides will be equal. Mathematically -
BC/YZ = AB/XY = AC/YZ = K [scale factor]
We can write -
8/(2[tex]\frac{2}{3}[/tex]) = 7/x
8/(8/3) = 7/x
8 x 3/8 = 7/x
3 = 7/x
x = 7/3
Therefore, the length of {x} is equivalent to 7/3 units.

Which percent is modeled? 9% 19% 91% 99%
Answer:
9%
Step-by-step explanation:
Count the squares side which is 10
Then Count the bootom side of the square which is 10
10 x 10 =100
Now count how many squares are filled. 9
9/100=9%
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
Total value = b
Percentage = a/b x 100
The percent modeled is 9%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
Total value = b
Percentage = a/b x 100
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of cells in the box = 100
Number of shaded cells = 9
The percentage of the shaded cells.
= (Number of shaded cells / Total number of cells) x 100
= 9/100 x 100
= 9%
Thus,
The percentage of shaded cells is 9%
The percent modeled is 9%.

The surface area of a cone is given by the formula S = πl + [tex]\pi r^2[/tex], the formula for I will be l = S/3.14 – [tex]r^2[/tex]. The correct option is C.
What is surface area?The surface area of a three-dimensional shape is the amount of space that surrounds it.
Starting with the given formula:
[tex]S = \pi l + \pi r^2[/tex]
We want to solve for l.
First, we can isolate the term with l on one side of the equation by subtracting [tex]\pi r^2[/tex] from both sides:
[tex]S - \pi r^2 = \pi l[/tex]
Then we can divide both sides by π to isolate l:
[tex]l = (S - \pi r^2) / \pi[/tex]
Therefore, the solution is:
[tex]l = (\frac{S}{\pi} - r^2)[/tex]
Thus, the correct option is C.

Step-by-step explanation:
Answer:
1)"rise over run" = 1.5/18 = 3/36 = 1/12 for the 1st section to the landing
2)slope is the change in height, the vertical change, divided by the change in horizontal distance
3)2nd section has slope 1/18 and covers 9 feet. That means it rises 1/2 foot

Step-by-step explanation:
This is because both sides are equal. And while this isn't the best explanation, my reasoning is because if you were to cut it in two and flip one side over the other side they would be equal. Also since all sides are not equal all are not the same angle. Apologies if this doesn't make sense, I am not good and explaining stuff. Best of luck on the assignment.

Jessica has an account with a credit union. Her account earns 2.6% simple interest yearly. Exactly a year and a half ago, she opened her account with $900.
How much interest has she earned so far?
Answer:
$35.1
Step-by-step explanation:
2.6% of 900 = 23.4
Since it's a year and a half you might want to divide by two.
2.6/2 = 1.3
1.3% of 900 = 11.7
add them up,
23.4 + 11.7 = 35.1
It's asking for how much she EARNED not HAS in her bank account in 1.5 years. So include what she earned with interest, do not include the 900 dollars because she didn't earn it with interest, she already had that.

What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
cost of 9 cans = $12
cost of 1 can= 12/ 9
= 4/3
Now, cost of 21 cans = 21* 4/3
= 7*4
= $28
Hence, for 21 can she has to pay $28.

A geologist wants to determine the distance across the widest part of a nearby lake. The geologist marked off specific points around the lake so that the line containing segment DE would be parallel to the line containing BC. The segment BC is selected specifically because it is the widest part of the lake. The segment DE is selected specifically because it is a short enough distance to easily measure. Use this diagram to answer the following questions.
1. Is ADE similar to ABC'? How do you know? *
Yes. All three sides are proportional.
Yes. Two or more angles are equivalent.
No. Side lengths are not proportional.
There is insufficient information to determine similarity.
2. If ADE is similar to ABC, and |AD| = 1,200 ft and |AB| = 3,600 ft, what is the length of segment BC?
2,700 ft

Answer:
1. Yes. Two or more angles are equivalent
2. 2700 ft
3. 3000 ft
Step-by-step explanation:
1.
∠EAD = ∠CAB (same angle)
∠AED = ∠ACB (because AC is a straight line and ED and CB are parallel)
2.

This means that for any given side for triangle AED, the corresponding side for triangle ACB is three times bigger. ED corresponds to CB, so:
900 x 3 = 2700
3.
We know that for any given side for triangle AED, the corresponding side for triangle ACB is three times bigger. AE corresponds to AC, so:
