The given polygons are similar. Find the value of x.
Answer:
x= 10 hope it helps have a nice day
Answer:
x=10
Step-by-step explanation:
[tex]\frac{8}{12} =\frac{x}{15}[/tex]
8×15=12x
120=12x
120/12=x
10=x
x=10
Hope this helps! :)
The law of reflection states that when a ray of light reflects off a surface, the
angle of incidence is equal to the angle of reflection.
Ramesh places
a mirror on level
ground to
determine the height of a pole (with traffic light fired on it). He stands at a
certain distance so that he can see the top of the pole reflected from the mirror.
Ramesh’s eye level is 1.5 m above the ground. The distance of Ramesh and the
pole from the mirror are 1.8 m and 6 m respectively.
On the basis of the above information, answer any four of the following
questions:
(i) Which criterion of similarity is applicable to similar triangles?
(a) SSA
(b) ASA
(c) SSS
(d) AA
(ii) What is the height of the pole?
(a) 6 metres
(b) 8 metres
(c) 5 metres

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 50, 60,72,... Find the 8th term.
Answer:
179.159
Step-by-step explanation:
Given the sequence :
50, 60, 72,..
The sequence given is a geometric sequence :
For a geometric sequence ;
ar^(n - 1)
a = first term
r = a2 / a1 = 60 / 50 = 1.2
The 8th term ; n =8
a8 = ar^(n - 1)
a8 = 50*1.2^(8 - 1)
a8 = 50*1.2^7
a8 = 50*3.5831808
a8 = 179.15904
a8 = 179.159 (nearest thousandth )

8 * 20 = 160
Just keep multiplying numbers by 8.
Please help! Thanks!
Step-by-step explanation:
Put the what given of y in equation 2 to equation of 1
So you get
[tex] \frac{4}{5} x + \frac{2}{5} x - 7 = - 4 \\ \frac{6}{5} x = 3 \\ x = \frac{15}{6 } \\ x = \frac{5}{2} [/tex]
Then put the value of x in second equation
You will get
[tex]y = - \frac{2}{5} \times \frac{5 }{2} + 7 \\ \\ y = 6[/tex]
How many solutions will this equation have? 3(x -4) = 2x + x -4
Answer:
The equation will have 0 solutions as it is incorrect equation

You deposit $500 in a savings account that earns 2.5% interest compounded yearly what is the balance in the account after 20 years
Answer:
the balance in the account after 20 years is $819
Step-by-step explanation:
The computation of the balance in the account after 20 years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $500 × (1 + 2.5%)^20
= $500 × 1.025^20
= $819
Hence, the balance in the account after 20 years is $819
There are 9 flash cards with numbers from 20 to 28 written on them. Laura drew the card with 22 on it. She is about to draw another card. What is the probability that the sum of the numbers on these two cards will be a multiple of 5?
Answer:
1 /4
Step-by-step explanation:
Multiples of 5 = (5, 10, 15, 20, 25, 30, 35, 40, 45)
Numbers on card : (20,21,22,23,24,25,26,27,28)
Number on first card = 22
To have a sum which is a multiple of 5 ; number on second card must be either :
23 or 28
22 + 23 = 45
22 + 28 = 50
Since only 2 of the cards will. Result in a sum which is a multiple of 5
Required outcome = 2
Total possible outcomes = (9 - 1) = 8
Probability = required outcome / Total possible outcomes
= 2 / 8
= 1 /4
3 1/4 x 6 2/3 simplified (worked out)
Answer:
65/3 = 21 2/3 = 21.666666667
21.66 = 21.661.
21.661 = (21.66 × 100)(1 × 100) = 2166100.
(2166÷2)(100÷2) = 108350 when reduced to the simplest form.
The is 21 2/3

Solve for the value of k. (k+8) 400
Answer: The answer to this math question about solving for the value of k with the given full of the angles is k = 6.
Step-by-step explanation: As always to remember, all of the forming angles to a straight line with a sum of 180 degrees, so anyways, here are 6 steps in order to solve for the value of k:
Step 1. First, let's find the measures of the value of all 3 angles, the measures of all 3 angles are, 8°, 90°, and 40° that looks in the equation form like this: [tex]7k + 8 + 90 + 40 = 180.[/tex]
Step 2. Next, after finding the measures of the value of all 3 angles, it's time to add all 3 angles up together that looks in the equation form like this: [tex]7k + 138 = 180.[/tex]
Step 3. Then, let's move positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side that looks in the equation form like this: [tex]7k = 180 - 138.[/tex]
Step 4. In addition to that, after moving positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side, it's time to subtract 138 degrees and 180 degrees that looks in the equation form like this: [tex]7k = 42.[/tex]
Step 5. Now last but not least is finally, after subtracting 138 degrees and 180 degrees, it's time to divide the both sides by 7 that looks in the equation form like this: [tex]\frac{7k}{7}=\frac{42}{7}.[/tex]
Step 6. Hence the value of k is 6.
I hope that my full given answer with my full given step-by-step explanation is very helpful to your own math question about solving for the value of k with the given full of the angles, please mark me as Brainliest, take care, always be safe, and have a great rest of the day and a great weekend! :D

Explanation :
First, you need to convert the mixed numbers into improper fractions. Then, you make sure the denominators are the same. (For example, in the first problem, you have to change the 3/4 to 6/8 to match the 17/8.) Then, you subtract the two fractions, and then turn the resulting improper fraction to a mixed number!
