ΔABC and ΔDEF appear to be similar. Which set of measurements prove that the two triangles are similar?

Answer:

-55

Step-by-step explanation:

Given expression:

               [tex]\frac{h}{5}[/tex] - 2  = -11

To solve this problem implies finding the variable h;

            [tex]\frac{h}{5}[/tex] - 2  = -11

Add +2 to both left and right hand side;

          [tex]\frac{h}{5}[/tex] - 2 + 2  = -11 + 2

             [tex]\frac{h}{5}[/tex]  = -9

Now, multiply both sides by 5;

         [tex]\frac{h}{5}[/tex] x 5  = -9 x 5

            h  = -45

Answer:

Step-by-step explanation:

Given the speed of Stephano’s marble is represented by the equation

f = 2.25s, where f is the distance in feet and s is the time in seconds.

To get the marble that will reach the 6-foot mark sooner, we will substitute the value of f = 6 and calculate the value of s as shown:

f = 2.25s

6 = 2.25s

s = 6/2.25

s = 2.67secs

Hence the 6 foot marble will reach after 2.67secs

Answer:

1.  $4200

2. $8000

3. Profit $3800

4. 90.48% (2 d.p.)

Step-by-step explanation:

40 x 105 = 4200

40 x 200 = 8000

8000 - 4200 = 3800

Rate of Return = (Final Value - Initial Value) divided by Initial Value

(8000-4200) divided by 4200 = 19/21 or 0.9047619048

= 90.48%

Answer:

1. $4,200

2. $8,000

3. $3,800 profit

4. 90.48%

Step-by-step explanation:

QUESTION 1:

The cost of one share two years ago was $105. Since you bought 40 shares, you would have to multiply that price by 40:

[tex]$105*40=4,200[/tex]

That means the total cost of purchasing 40 shares two years ago was $4,200.

QUESTION 2:

One share currently costs $200. Just like with problem 1, since they're asking about all 40 shares, you need to multiply that price by 40.

[tex]200*40=8,000[/tex]

That means that 40 shares is currently valued at $8,000.

QUESTION 3:

Profit or loss is calculated by subtracting the final value by the initial value. In this case, subtracting the current price by the price you originally bought the shares for.

[tex]8,000-4,200=3,800[/tex]

Because it's a positive number, you know that you've made a profit of $3,800 off of 40 shares.

QUESTION 4:

Rate of return is calculated by dividing the profit (or loss) by the original cost:

[tex]3,800/4,200=0.9048[/tex]

Of course, since rate of return is expressed in a percentage, you would need to multiply 0.9048 by 100 and tack a percent sign onto the end, giving you 90.48%. (I rounded the number to the nearest hundredth.)

Answer:

a) 676, 1296

b) 17576, 46656

c) 456976, 1679616

Step-by-step explanation:

firstly we know that there are 26 letters in the alphabet.

there are 26 ways of choosing the first character and 26 ways choosing the second character,

Therefore, the possible number of domains with two leeter is;

n = 26²

= 26 × 26

= 676

now when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore the possible number of domains with two characters is;

n = 36²

= 36 × 36

= 1296

b)

there are 26 ways of choosing each character

therefore, the possible number of domains with three letters is

n = 26³

= 26 × 26 × 26

= 17576

when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore , the possible number of domains with three characters is;

n = 36³

= 36 × 36 × 36

= 46656

c)

there are 26 ways of choosing each character, therefore the possible number of domains with four letters is;

n = 26⁴

n = 26 × 26 × 26 × 26

n = 456976

when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore, the possible number of domains with four characters is;

n = 36⁴

n = 36 × 36 × 36 × 36

= 1679616

There are 676 domain names consisting of just two letters in a sequence that can be formed.

There are 1296 domain names of length two are there if digits, as well as letters, are per-mitted as characters.

There are 17576 domain names are there consisting of three letters in sequence.

There are 46656 of this length are there if either letters or digits are permitted.

As of April 2006, roughly 50 million web domain names were registered.

1. How many domain names consisting of just two letters in sequence can be formed?

There are 26 letters in the English alphabet.

Combining 2 domain names with letters alone will be;

[tex]\rm =n^2\\\\ = 26^2\\\\ =26 \times 26\\\\=676[/tex]

2. How many domain names of length two are there if digits, as well as letters, are per-mitted as characters.

If digits are allowed with letters:

There are 10 digits from 0-9.

Therefore 26 letters + 10 digits = 36

[tex]\rm = n^2 \\\\= 36^2 \\\\ = 36 \times 36 \\\\ = 1296[/tex]

3. How many domain names are there consisting of three letters in sequence?

There are 26 ways of choosing each character;

Therefore, the possible number of domains with three letters is;

[tex]= \rm n^3\\\\= 26^3\\\\= 26 \times 26 \times 26\\\\= 17576[/tex]

4. How many of this length are there if either letters or digits are permitted?

The digits are allowed, there are 26 + 10 = 36 characters to be used in total

Therefore, the possible number of domains with three characters is;

[tex]\rm = n^3 \\\\= 36^3 \\\\ = 36 \times 36 \times 36\\\\ = 46656[/tex]

Answer: 22/35

The least common multiple that is divisible by both a and b is the smallest positive integer. The number of times Ram, Hari and Shyam will meet in 180 days is 30 times.

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

Given that Ram, Hari and Shyam go for a swim after a gap of every 1 day, 2 days and 3 days respectively. Therefore, the number of day after which all three together will meet can be found by taking the LCM.

Since the LCM of the 1, 2 and 3 are 6. Therefore, the three of them will meet after every 6 days.

Thus, if they all meet today then within 180 days, the number of times they meet is,

Number of times they meet = 180 days/6 = 30

Hence, the number of times Ram, Hari and Shyam will meet in 180 days is 30 times.

Answer:

[tex] 5(d - 4) [/tex]

Step-by-step explanation:

Entrance fee per head = d

Entrance fee for the 5 friends = 5*d = 5d

Booklet of ride ticket per head = 2.5d

Booklet of ride ticket for the 5 friends = 5(2.5d)

Meal ticket per head = d - 4

Meal ticket for the 5 friends = 5(d - 4)

Total amount paid altogether by the five friends = [tex] 5d + 5(2.5d) + 5(d - 4) [/tex]

Answer:

Large number: 20

Small number: 12

Step-by-step explanation:

Hello!

This problem is a word problem, and if we assign variables to find each of the numbers, it could help.
A variable is usually an unknown number that stands for that unknown.
Since in this problem we know there is a small and large number, let's assign the large number as the variable x and small number as variable y.

For the first part, it says two numbers whose difference is 8, which means the large number minus the smaller number equals 8.

x-y=8

For the second part is tricky. It's saying that the small number times three is 16 more than the large number itself. When constructing a equation, this is what we get:

x+16=3y   x plus 16 equals 3 times y

To solve this equation together so we can make it super easy, let's do the method of substitution, which is where we make an equation equal to a variable and input that equation into the second equation.
We can use x-y=8 to input, we can rearrange y and plug it to the right side to get x=8+y

Since x equals 8+y, let's input this into the second equation.

(8+y)+16=3y    input the rearranged equation into the second

24+y=3y         combine like terms

    -y   -y

24=2y              divide by two to get y by itself

12=y

We aren't done yet! We have to find x still; let's use the previous first equation to find x. We know y=12, so let's plug it in.

x-y=8    original formula

x-12=8      plug it in

+12  +12

x=20

Therefore, the large number is 20, and smaller number is 12.

Answer:

12 and 20

Step-by-step explanation:

                         small=x

                         big= (x+8)

24 = 2x

x=12 (small)
