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 1

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!

Find the lengths of the segments with variable expressions.

Answers

Answer:

EF = 8

Step-by-step explanation:

The midsegment EF is half the sum of the parallel bases , that is

x = [tex]\frac{x-5+2x-3}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

2x = 3x - 8 ( subtract 2x from both sides )

0 = x - 8 ( add 8 to both sides )

8 = x

Thus

EF = x = 8

AD = x - 5 = 8 - 5 = 3

BC = 2x - 3 = 2(8) - 3 = 16 - 3 = 13

Lionel has at most 63/8 cups of flour to bake cookies and a cake. Lionel uses 7/4 cups of flour to make the cake. If each batch of cookies takes 3/2 cups of flour, how many batches of cookies, x, can Lionel bake? Select the inequality that includes the maximum number of batches of cookies Lionel can bake.


A. x⊇49/8

B. 49/8⊆x

C. 49/12⊆x

D. x⊇49/12

Answers

Answer:

x ≤ 49 / 12

Step-by-step explanation:

Total cups of flour = 63 /8

Cake = 7/4 cups

Cookies = 3/2 cups per batch

Flour left after baking cake :

63/8 - 7/4

(63 - 14) / 8

49 / 8

Batch of cookies which can be baked, x

Flour left / cups of flour per batch of cookies

x ≤(49 / 8) ÷ (3 / 2)

x ≤ (49 /8) * 2/3

x ≤ 98 / 24

x ≤ 49 / 12

The breadth of the rectangular firls is 20m less than its length.. Find its dimensions if perimeter is 160 m

Answers

Answer: length of the rectangular firls = 50

and the breadth = x-20m= 50-20m =30m

Step-by-step explanation:

The perimeter of a rectangle is given as  2(l+b)

let the length be represented as x

such that the breadth = x-20m

so our expression for the perimeter of the rectangular firls becomes

Perimeter = 2l+ 2b

160= 2x + 2 ( x-20)

160= 2x+ 2x-40

160+40 =4x

200= 4x

x= 200/4

x= 50

So the length of the rectangular firls = 50

and the breadth = x-20m= 50-20m =30m

Answer:

Length =60m

Breadth= 20m

Step-by-step explanation:

Breadth of the rectangular firls = 20m

Perimeter = 160m

Length = X

Perimeter of a rectangle = 2(L +B)

Where L= Length

           B = Breadth

160 = 2( 20 + X)

160 = 40 +20X

160- 40 =20X

120= 20X

20X = 120

X = 120/20

X = 60

The dimensions are:

Length =60m

Breadth= 20m
