Answer:

40liters

Step-by-step explanation:

Given data

1/5 full holds 16 liters

1/2 full barrel will hold???

Let 1/2 full barrel hold x liters

1/5 holds 16 liters

1/2 will hold x

cross multtiply

1/2*16= x/5

8= x/5

x= 8*5

x= 40 liters

Hence 1/2 full will hold 40liters

180 marbles are in the jar.

Combining operands with a single arithmetic operator specifies an arithmetic operation. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations. in general, we use PEMDAS for calculating various arithmetic operations.

Given 25% of the marbels ar red. and also given 45 marble are red.

Hence Total marble will be,

Total marbles = [tex]\frac{45* 100}{25}[/tex] = 180.

Therefore the total number of marbles in the jar is 180.

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

Answer:

[tex]A=2833.71\ cm^2[/tex]

Step-by-step explanation:

Given that,

The height of the cylinder, h = 30 cm

The radius of the cylinder, r = 11 cm

We need to find the total surface area of the cylinder. The formula for the total surface area of the cylinder is given by :

[tex]A=2\pi rh+2\pi r^2\\\\A=2\pi \times 11\times 30+2\pi \times (11)^2\\\\A=2833.71\ cm^2[/tex]

So, the total surface area of the cylinder is [tex]2833.71\ cm^2[/tex].

Answer

Option 2, 4 and 5 :)

Step-by-step explanation:

Option 2 is already simplified to 20x + 30y

Option 4,

10*2x=20x and 10*3y= 30y so option 4 also simplifies to 20x + 30y

Next Option 5, 10*2x= 20x and 10*3y=30y. So it's also 20x + 30y

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:

3950 feet squared

Step-by-step explanation:

So first you have to multiply 75 by 50, so that is 3750.

Next you have to multiply 20 by 10 and you get 200.

Finally you had both 3750 and 200 in order to get 3950 and that is why the total area of the farm is 3950 feet squared.

.......................

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.

Step-by-step explanation:

Answer:

b and d

Step-by-step explanation:

Sum = 4

Product = -32

Factors = 8 , (-4)

x² + 4x - 32 = x² + 8x - 4x - 4*8

                   = x(x + 8) - 4(x + 8)

                  = (x + 8)(x - 4)

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

Answer:

one solution

Step-by-step explanation:

2( 4 + 1 0 ) = 8 +2 0   = 2 8 + 2 0

Subtract

Simplify  

Subtract  8  from both sides of the equation
