The younger sister is 29.

The older sister is 49.

Mr Fishman's age is 47.

Let:

The difference between the older sister and younger sister's age: y - x = 20 equation 1

Mr Fishman's is 11 years less than twice his young sister's age: 2x - 11 = c equation 2

The difference between Mr Fishman and his older sister's age : y - c = 2

y  - 2 = c equation 3

Let equation 2 and 3 be equal : 2x - 11 = y - 2

2x - y = 11 - 2

2x - y = 9

-y + 2x = 9 equation 4

The two equations that would be used are:

y - x = 20 equation 1

-y + 2x = 9 equation 4

Add both equations together

x = 29

Substitute for x in equation 1

y - 29 = 20

y = 29 + 20

y = 49

y - c = 2

49 - c = 2

c = 49 - 2

c = 47

Answer:

Step-by-step explanation:

It takes Layla 45 minutes to make 9 bracelets on her own.

45 divided by 9 equals 5. It takes Layla 5 minutes to make one bracelet.

Layla and Amelia can make 9 bracelets in 20 minutes.

20 divided by 9 equals 2 and 2/9.

5 - 2 2/9= 2 7/9

2 7/9 times 9 equals 25

Amelia can make 9 bracelets in 25 minutes

So it takes Layla 56 minutes to make 9 ( 45 divided by 9 = 5) so that means in 20 minutes Layla will make 4 bracelets.

this means it will piece together as Layla would make 4 while Amelia makes 5. So i think on Amelia's own it'll take her 40 minutes.

so sorry if i'm wrong :(

12th term of the geometric sequence is 97,656,250

In the given statement is:

Find the 12th term of the geometric sequence 2,10,50

What is Geometric Sequence?

A Geometric Sequence is a special type of sequence where the ratio of every two successive terms is a constant. This ratio is known as a common ratio of the geometric sequence.

Now, to find the 12th term of geometric sequence:

Formula of Geometric Sequence:

[tex]a_{n} =a_{1}r^n^-^1[/tex]

[tex]a_{1}=2\\ \\[/tex]

r = 10/2 =5

[tex]a_{12}=2(5)^1^2^-^1\\ \\a_{12}=2(5)^1^1\\\\\\a_{12}=2(48,828,125)\\ \\a_{12} = 97,656,250[/tex]

Therefore, 12th term of the geometric sequence is 97,656,250

Answer:

Step-by-step explanation:

The equation of the line is y = 5x + 35

The equation of a line can be represented in a slope intercept form as follows:

y = mx + b

where

Therefore, line that are parallel have the same slope.

Therefore, if line one slope is 5, then the slope of the unknown line will be 5.

Hence,

y = 5x + b

let's find the y-intercept using (-8, -5)

-5 = 5(-8) + b

-5 = -40 + b

b = -5 + 40

b = 35

Therefore, the equation of the line is y = 5x + 35

48 persons make up a party. There are seven times more adults than children in the world. Males outnumber females two to one. If the party has five girls. The total number of male adults are15

The total number of people are in the party is equal to 48

Let the number of children be x

So, the number of adults in the party is equal to 7 x

x + 7 x =48 ( This is a linear equation)

So, the number of children in the comes to be 6

Number of adults in the party = 6 * 7 = 42

Now let number of males be y

So total number of females = 2 y

Y+2y = 48 ( This is a linear equation)

Y=16

Therefore, the number of males is 16 and number of females is 32

Number of children in the party is 6 and female child is equal to 5

Then, number of male children =6-5 = 1

So total males in the party is equal to 16

Adult males =total number of males - number of male children

=16 - 1 = 15

Hence the total number of male adults =15

Answer:

  thousands place: 4th one to the left of the decimal point, 1000.

Step-by-step explanation:

You want the number place of a 1 that has a value 100 times that of the 1 in 314.

The digit 1 in the number 314 is in the "tens place." It signifies 1 ten is part of the value of the number 314.

The value of a digit 1 that is 100 times that will be ...

  10 × 100 = 1000

That is, the digit will be found in the "thousands place," two digits to the left of the location in the number 314.

The 1 with a value of 1000 is written in the thousands place, the 4th place to the left of the decimal point.

[tex]\textsf{d)} \quad \dfrac{5}{6}, \quad \dfrac{25}{6}[/tex]

Step-by-step explanation:

Given:

[tex]12 \cos \left(\dfrac{2 \pi}{5}x\right)+10=16, \quad \textsf{when}\; \left(\dfrac{2 \pi}{5}x\right)\; \textsf{is in radians}.[/tex]

Subtract 10 from both sides of the given equation:

[tex]\implies 12 \cos \left(\dfrac{2 \pi}{5}x\right)=6[/tex]

Divide both sides of the equation by 12:

[tex]\implies \cos \left(\dfrac{2 \pi}{5}x\right)=\dfrac{1}{2}[/tex]

Take the inverse of cosine of both sides:

[tex]\implies \dfrac{2 \pi}{5}x = \cos^{-1}\left(\dfrac{1}{2}\right)[/tex]

[tex]\implies \dfrac{2 \pi}{5}x =\dfrac{\pi}{3}+2 \pi n, \dfrac{5 \pi}{3}+2 \pi n[/tex]

Multiply both sides by 5:

[tex]\implies 2 \pi x=\dfrac{5 \pi}{3}+10 \pi n, \dfrac{25 \pi}{3}+10 \pi n[/tex]

Divide both sides by 2π:

[tex]\implies x=\dfrac{5 \pi}{6 \pi}+\dfrac{10 \pi}{2 \pi}n, \dfrac{25 \pi}{6 \pi}+\dfrac{10 \pi}{2 \pi}[/tex]

Simplify:

[tex]\implies x=\dfrac{5}{6}+5n, \dfrac{25}{6}+5n[/tex]

The two smallest possible solutions for x are when n = 0:

[tex]\implies x=\dfrac{5}{6}, \quad x=\dfrac{25}{6}[/tex]
