Answer:

2/3

Step-by-step explanation:

2/3=0.6666666667 or 0.6 recuring

-9 in power means that the value is in fractional and the 10 base is multipied 9 times and put it on denominator.

8.6 = 86 x 10^-1

Let's multiply :

86 x 10^-1 x 10^-9

= 86 x 10^-10

= 86/10000000000

=0,0000000086

Note : if you don't know about how 10^-1 x 10^-9 returns 10^-10, it's because of exponential rules. If the base are same wuth each other, then just do the addition operation in the exponent like this :

10^(-1+(-9))

= 10^(-1-9)

=10^-10

Hope it helps :)

Answer:

b. PHP 31,250.00

Step-by-step explanation:

Simple interest = principal × rate × time

Principal = PHP 25,000

Rate = 2.5%

Time = 10 years

Simple interest = principal × rate × time

= PHP 25,000 × 2.5% × 10

= 25,000 × 0.025 × 10

= 6,250

Simple interest = PHP 6,250

Investment after 10 years = principal + simple interest

= PHP 25,000 + PHP 6,250

= PHP 31,250

Investment after 10 years = PHP 31,250

Answer: 1 and a half batches

Step-by-step explanation:

Answer:

a) x = 34

b) yes, it checks out

Step-by-step explanation:

2x - 5 = 3(4 + 1/2x)

multiply both sides by 2 to eliminate fraction

2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x

x - 10 = 24

x = 34

check

2(34) - 5 = 3(4 + 34/2)

68 - 5 = 3(4 + 17)

63 = 3(21)

63 = 63

7×4=28

Step-by-step explanation:

hope this helps you out

The solution to the set is .x = negative 8 and x = 24.

The separation of a number from a number line's origin is referred to as a number's absolute value. It is denoted by the symbol |a|, which specifies the size of any integer 'a'. Any integer's absolute value, regardless of its sign or whether it is positive or negative, will be a real number. The modulus of a, which is how two vertical lines |a| are used to symbolise it.

Given:

|4 - x/2| = 8

So, there are two possibilities

4- x/2 = 8  or 4 - x/2 = -8

-x/2 = 8-4 or -x/2 = -8-4

-x/2 = 4  or -x/2 = -12

x= -8 or x= 24

Hence, the solution to the set is .x = negative 8 and x = 24

Answer:

-2(7) + -2(5g)

Step-by-step explanation:

Using the distributive property we can confirm that:

-2(7) + -2(5g) = -2(7+5g)

Answer:

−14−10g

Step-by-step explanation:

First, solve the product:

-2 ⋅ 7 - 2 ⋅ 5g

Multiply -2 times 7 to -14.

So, the equivalent expression would be:

-14 - 2 ⋅ 5g = -14 - 10g

-14 - 10g

Solution :

We have to find the largest fraction in each group.

a). [tex]$\frac{5}{6}$[/tex] and [tex]$\frac{29}{36}$[/tex]

    [tex]$\frac{5}{6}$[/tex]  →  when we divide the number 5 with 6, we get 0.833

    [tex]$\frac{29}{36}$[/tex] → when we divide 29 by 36, we get the value 0.805

Therefore, in this group, [tex]$\frac{5}{6}$[/tex] is the largest fraction.

b).  [tex]$\frac{5}{12}$[/tex] and [tex]$\frac{3}{8}$[/tex]

     [tex]$\frac{5}{12}$[/tex]  →  when we divide the number 5 with 12, we get 0.416

    [tex]$\frac{3}{8}$[/tex] → when we divide 3 by 8, we get the value 0.375

Therefore, in this group, [tex]$\frac{5}{12}$[/tex] is the largest fraction.

c).  [tex]$\frac{2}{5}$[/tex] and [tex]$\frac{19}{45}$[/tex]

     [tex]$\frac{2}{5}$[/tex] →  when we divide the number 2 with 5, we get 0.40

    [tex]$\frac{19}{45}$[/tex] → when we divide 19 by 45, we get the value 0.42

Therefore, in this group, [tex]$\frac{19}{45}$[/tex] is the largest fraction.

d).  [tex]$\frac{5}{7}$[/tex], [tex]$\frac{13}{14}$[/tex] and  [tex]$\frac{19}{21}$[/tex]

      [tex]$\frac{5}{7}$[/tex] →  when we divide the number 5 with 7, we get 0.714

    [tex]$\frac{13}{14}$[/tex] → when we divide 13 by 14, we get the value 0.928

    [tex]$\frac{19}{21}$[/tex]  → when we divide 19 by 21, we get the value 0.904

Therefore, in this group, [tex]$\frac{13}{14}$[/tex]  is the largest fraction.

The equivalent value of the expressions are solved by the exponents

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

A = 25ˣ

On simplifying , we get

A = ( 5 . 5 )ˣ

A = ( 25 )ˣ

And , A = 5ˣ . 5ˣ

From the laws of exponents , we get

mᵃ×mᵇ = mᵃ⁺ᵇ

A = 5²ˣ

A = 25ˣ

Hence , the expressions are ( 5 . 5 )ˣ = 5²ˣ = 5ˣ . 5ˣ = 25ˣ

Answer:

5

Step-by-step explanation:

Since the two lines are parallel, they must have the same slope. This means that the slope of green line must be 5 just like the red line. You can also use the slope formula (rise/run) or change in y divided by change in x.
