Answer:

1 x (27a^2+72a+28)  or 1(27a^2+72a+28)

Step-by-step explanation:

First find the GCF (greatest common factor) of 27a squared 72a and 28. It is 1 because there is nothing else that can go in.

So put 1 outside the parentheses and keep the terms

1 x (27a^2+72a+28)

Complete question :

Tim knows the volume and base area of a wooden chest that is in the shape of a rectangular prism. If the volume is 5/24 cubic unit and the base area is 1/5 square unit, what is the height of the chest?

Answer:

1 1/24 units

Step-by-step explanation:

Volume of a rectangle prism:

Volume = Lenght * Width * Height

Base area = Length * width

Volume = Base area * Height

Volume = 5/24 unit³

Base area = 1/5 unit²

Plugging values into our formula :

5/24 = 1/5 * height

Divide both sides by 1/5

Height = 5/24 ÷ 1/5

Height = 5/24 * 5/1

Height = 25 / 24

Height = 1 1/24

= 1 1/24 units

Answer:

B. 1 1/24 units

Answer:

1244/999

Step-by-step explanation:

So we have 1.245245245245.... which we call x.

If we times this by 1000 (because 3 digits repeat) we get

1000x = 1245.245245245....

Subtract x from both sides:

999x = 1245.245245245... - 1.245245... = 1244

This means that x = 1244/999

This fraction cannot be simplified so this is the answer.

If you want to include the 1 in the repeating (1.2451245...) do the same but the sequence is 4 digits so times by 10000 instead.

Row 2 Column 2: 1/25

Row 2 Column 3: 0.04

Row 3 Column 1: 75%

Row 3 Column 3: 0.75

Row 4 Column 1: 80%

Row 4 Column 2: 4/5

Answer:

4 as a fraction is 1/25 as a decimal 0.04

3/4 as a percentage is 75% as a decimal 0.75

0.8 as a fraction 4/5 and as a percentage is 80%

Step-by-step explanation

Answer:

1) The  series of equations that can be used to find the numbers are

7·x + 3·y = 54...(1)

x = y + 2...(2)

2) The first number is 6

The second number is 4

Step-by-step explanation:

1) The given parameters for the numbers are;

7 times the first number + 3 times the 2nd number = 54

The first number = The 2nd number + 2

Let 'x' represent the first number and let 'y' represent the second number

The following series of equations can therefore be used in finding the numbers;

7·x + 3·y = 54...(1)

x = y + 2...(2)

2) By substituting the value of x = y + 2 from equation (2) into equation (1) gives;

7·x + 3·y = 54

∴ 7×(y + 2) + 3·y = 54

7·y + 14 + 3·y = 54

10·y + 14 = 54

10·y = 54 - 14 = 40

y = 40/10 = 4

The second number = y = 4

The first number, x = y + 2 = 4 + 2 = 6

The first number, x = 6.

Answer:

Step-by-step explanation:

Sum of nth term of a GP is expressed as;

Sn = a(r^n-1)/r-1

The sum of the first 8 terms of a GP is expressed as;

S8 = a(r^8 - 1)/r-1

The sum of first 4 terms is expressed as;

S4 = a(r^4 - 1)/r-1

If the sum of the first 8 terms of a GP is five times the sum of first 4 terms then

S8 = 5S4

a(r^8 - 1)/r-1 = 5[a(r^4 - 1)/r-1]

r^8 - 1 = 5(r^4 - 1)

r^8 - 1 = 5r^4 - 5

r^8 - 5r^4 = -5+1

r^4(r^4 - 5) = -4

r^4 - 5 = -4

r^4 = -4+5

r^4 = 1

r = 1

Hence the common ratio is 1

Step-by-step explanation:

I tried to search it up to get it correct but all it showed me was useless websites that didn't give me the answer

Given:

Lamont cotton is 4% commission on the first 10,000 of monthly sales and 10% on all sales over 10,000.

Consider his last month sales is 38,000.

To find:

The total commission.

Solution:

4% commission on the first 10,000 of monthly sales is

[tex]10,000\dfrac{4}{100}=400[/tex]

Sales over 10,000 is

[tex]38,000-10,000=28,000[/tex]

10% commission on all sales over 10,000 is

[tex]28,000\times \dfrac{10}{100}=2,800[/tex]

Now, the total commission is

[tex]400+2,800=3,200[/tex]

Therefore, the total commission is 3,200.

Step-by-step explanation:

so therefore mark jogged 2 36/70km more than his sister

The number of kilometers that Mark jog more than his sister will be 32 / 35 km.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Mark jogged 3 ⁵/₇ km. His sister jogged 2 ⁴/₅ km.

Convert the mixed fraction number into a fraction number. Then we have

3 ⁵/₇ = 3 + 5/7 = 26/7

2 ⁴/₅ = 2 + 4/5 = 14/5

Then the number of kilometers that Mark jog more than his sister will be given as,

⇒ 26/7 - 14/5

⇒ 32 / 35 km

The number of kilometers that Mark jog more than his sister will be 32 / 35 km.

Answer:

56.7°

Step-by-step explanation:

We solve this above question using the Trigonometric function of Sine

sin x = Opposite side/Hypotenuse

Opposite = 66mm

Hypotenuse = 79 mm

sin x = 66/79

x =arc sin(66/79)

x = arcsin(0.8354430379746836)

x = 56.661998553°

Approximately = 56.7°
