(c) = 4 Boards

Step-by-step explanation:

(a):

0.8 x 2/5

8/10 x 4/10

(8 x 4) / (10 x 10)

(32) / (100)

0.32 or 8/25

A rectangle is 10 cm long and it's perimeter is 26cm . find the breath of the rectangle
gavmur [86]

Answer:

the width of a rectangular is 3 cm

Step-by-step explanation:

Length L = 10 cm

Perimeter P = 26 cm

Width W = ?

perimeter = 2L + 2W

26 = 2(10) + 2W

26 - 20 = 2W

6 = 2W

W = 6 / 2

W = 3 cm

therefore,  the width of a rectangular is 3 cm

Please help!!! Ella and Margaret were at a carnival. They each got a ticket for the Ferris wheel. Ella got a snow cone, and Marg
seraphim [82]

Answer:

(B) $5.25

Step-by-step explanation:

We can create an equation to represent this problem.

Let's assume f is the cost of a ferris wheel ticket, s is the cost of a snow cone, and c is the cost of a cotton candy.

We bought two ferris wheel tickets, one snow cone, and one cotton candy. After a discount of 6 dollars, the price was 12.75.

This makes the equation 2f + s + c - 6 = 12.75

Since we know the value of each ferris wheel ticket and the snow cone, we can simplify our equation by substituting in these values.

2(5) + 3.50 + c - 6 = 12.75\\\\10 + 3.50 + c - 6 = 12.75\\\\7.5 + c = 12.75

We can now subtract 7.5 from both sides to get the value of c, the cotton candy price.

7.5 + c - 7.5 = 12.75 - 7.5\\\\c = 5.25

So the cotton candy cost $5.25.

Hope this helped!
