How can you use ratios to determine if two figures are similar?
Answer:
Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor .

Find the value of x. Round to the
nearest tenth.
40°
х
7
x =
Answer:
x ≈ 10.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{x}[/tex] ( multiply both sides by x )
x × sin40° = 7 ( divide both sides by sin40° )
x = [tex]\frac{7}{sin40}[/tex] ≈ 10.9 ( to the nearest tenth )

What is “F” in this triangle problem thingy
Answer:
f=43
Step-by-step explanation:
Hey There!
So if you didn't know the exterior angle (aka f) is equal to the sum of the opposite interior angles
so essentially what i am saying is that
19+24=f
19+24=43
therefore
f=43
hope this helps :)

Danielle is keeping track of the amount of money in her lunch account. She starts with $36 in the account and uses 3 dollars every day for lunch. Which equation below could she use to track the amount of money in her account if M=the money in her account and d=the number of days?
M = 36 + 3d
M = - 3d + 36
M = - 36 + 3d
M = 3 + 36d
Answer:
M=-3d+36

If
x + 2y = 1
X– 2y = 13
then y =
Answer:
y = -3
Step-by-step explanation:
x + 2y = 1 then x = 1 - 2y
x– 2y = 13
substitute for x:
1 - 2y - 2y = 13
simplify:
-4y = 12
y = -3
x = 7

Answer:
This shape is a hexagon. Angles in a hexagon add to 720 degrees.
2(y) + 4(2y-20) = 720
2y + 8y-80 = 720
10y-80=720

You deposit $300 in a savings account. The account earns 2% simple interest per year.
a. What is the interest earned after 10 years?
The interest earned is $ after 10 years.
b. What is the balance after 10 years?
The balance is $ after 10 years.
Answer:
Answer:
a. ----> $10
b. ----> $110
Step-by-step explanation:
Step-by-step explanation:
principle ( p ) = $100
time ( t ) = 10 years
rate ( r ) = 11%
simple interest = (p × r × t)÷ 100
= ( $100 × 11 × 10 )÷ 100
= 11000 ÷ 100
= $110
interest = simple interest - principle
interest = $110 - $100
= $10

A sequence can be generated by using an = 4a(n - 1)) where a= 6 and n is a whole
number greater than 1. What are the first four terms in the sequence?
Given:
The sequence can be generated by
[tex]a_n=4a_{(n - 1)}[/tex]
Where [tex]a_1= 6[/tex] and [tex]n[/tex] is a whole number greater than 1.
To find:
The first four terms of the given sequence.
Solution:
We have,
[tex]a_n=4a_{(n - 1)}[/tex] ...(i)
It is given that [tex]a_1= 6[/tex]. So, for [tex]n=2[/tex], we get
[tex]a_2=4a_{(2 - 1)}[/tex]
[tex]a_2=4a_1[/tex]
[tex]a_2=4(6)[/tex]
[tex]a_2=24[/tex]
Putting [tex]n=3[/tex] in (i), we get
[tex]a_3=4a_{(3- 1)}[/tex]
[tex]a_3=4a_2[/tex]
[tex]a_3=4(24)[/tex]
[tex]a_3=96[/tex]
Putting [tex]n=4[/tex] in (i), we get
[tex]a_4=4a_{(4- 1)}[/tex]
[tex]a_4=4a_3[/tex]
[tex]a_4=4(96)[/tex]
[tex]a_4=384[/tex]
The first four terms of the given sequence are 6, 24, 96,384.
Therefore, the correct option is C.

What is X and Y? I will give brainliest to whoever shows work and explains how to do the problem and if its correct.
Answer:
x = 5([tex]\sqrt{3}[/tex])
y = 10
Step-by-step explanation:
1st, we need to find the angles on the triangle before we can solve for side lengths.
Line Y is intercepted by line X which forms 2 supplementary angles.
These angles add up to 180 so 180 - 150 = 30 therefor the angle is 30 degrees
Next, using the vertical angle theorem, we see that there is a right angle and using this theorem, we can determine this is a right triangle and that angle is 90 degrees
Using the triangle sum theorem, we know a triangle's sum is = to 180 degrees
90 + 30 + x = 180
120 + x = 180
x = (180 - 120)
x = 60
We now determined this is a 90-60-30 triangle
The opposite of the 30 degree angle is the 5 unit measurement
According to this theorem 5 is equal to x because the side opposite of the 30 degree angle is = to x (not the side variable, the variable for this theorem)
We now solve the rest
x = 5
2x (opposite of 90 degrees) = 10
5x = 5([tex]\sqrt{3}[/tex]) (This is in its simplest form)
So now based upon this,
x = 5([tex]\sqrt{3}[/tex])
y = 10
Help pls 10 points
A x=56
B x=156
C x=166
D x=66
D: x=66
Step-by-step explanation:
As we know the angle is 90 degree.Then x+24 degree is equal to 90 degree as whole part axiom. If we subtract 24 from 90 we get 66
Hope it's helpful!!

I need help on 1, 2, an 3
Answer: 1. A) 2/5 B) X= -5 Y= 2
2. A) -3/2 B) X= 2 Y= 3
3. A) -2/3 B) X= -3 Y= -2
Step-by-step explanation: A) Look where the line intersects perfectly through a corner of one of the boxes, find the next one closes to that count how many it goes up and how many across. Rise/Run so the amount it goes up goes on the top of the fraction and the amount across on the bottom of the fraction.
B) This is where the line intersects the X and Y axis
