13/11,24/13,11/13,11/24

Answer:

65:55, 55:65, 55:120

Step-by-step explanation:

Fiberglass boats are = 65 because 120-55=65

Fiberglass to wood means that there is a 65:55 ratio because there are 65 fiberglass boats and 55 wood boats

wood to other, this is kind of a trick question, but its 55:65 because there are 65 other boats and 55 wooden boats

wood to total, this is 55:120 there are 55 wood boats and 120 total boats.

What are some rules of exponents?

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

We also know that a multiplied by a 'n' number of times can be written

as aⁿ.

Now,  2 to the power of 6 in exponent form is 2⁶ which states 2 is multiplied by 2, 6 times.

Therefore, From the given options the expression that is equivalent to

2⁶ is 2x2x2x2x2x2.

sewing a border of ribbon onto her rectangular picnic blanket. The long side of the blanket is 70cm and the short side is 40cm. How much ribbon will she need?

Answers

Answer:

[tex]220[/tex] cm

Step-by-step explanation:

We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be [tex]2(l+w)[/tex], where [tex]l[/tex] is the rectangle's length and [tex]w[/tex] is the rectangle's width. We are given that [tex]l=70[/tex] and [tex]w=40[/tex]. Therefore, [tex]2(70+40)=2*110=220[/tex] cm of ribbon will be needed. Hope this helps!

Solve the inequality for x.
22 >x-5

Answers

Answer:

x < 27

Step-by-step explanation:

22 > x - 5

Subtract x from both sides.

-x + 22 > -5

Subtract 22 from both sides.

-x > -27

Divide both sides by -1. Remember that when you multiply or divide an inequality by a negative number, the inequality sign changes direction.
