Answer: 5%

Step-by-step explanation:

To find the sales tax, find the difference between before and after tax:

0.63 - 0.60 = 0.03

To find the percentage, divide the difference by the cost of the product:

0.03/0.60 = 0.05

Multiply by 100 to find percent sales tax:

0.05 x 100 = 5%

To find the area of a rectangle and a parallelogram, use the formula:

$a = l \times h$

(Area = Length x Height)

Q4.

$a = 1 \frac{1}{4} \times 3\frac{1}{4} = 4 \frac{1}{16}$

Q6.

$a = 1 \frac{2}{3} = 3 \frac{1}{2} = 5 \frac{5}{6}$

3 rhombi are connected at a point, side by side. All sides are congruent. Juan is making a model out of rhombi. Each rhombus wil

Wewaii [24]

Rhombus has all sides equal. The total amount of paper that will be needed to cover the wall is 396 in².

Given to us

Each rhombus will be 6 inches tall and 4 inches wide.

A.)

The area of each rhombus can be found using the formula,

$Area = \dfrac{1}{2} \times d_1 \times d_2$

We know that diagonals of the rhombus are of length 6 in and 4 in. therefore,

$Area = \dfrac{1}{2} \times 6 \times 4\\\\Area = 12\ in^2$

Hence, the area of the single rhombus is 12 in².

We know that the wall is 11 feet long, also, 1 foot = 12 inches, therefore,

11 feet = 132 in.

Now, since the wall is 132 in long and the width of the rhombus is 4 in, therefore, the number of rhombi that will be needed,

$\dfrac{132}{4} =33$

Hence, the number of rhombi that will be needed is 33.

We know the area of each paper rhombus, also, we know the number of rhombi that will be needed. Therefore,

$33 \times 12 = 396\ in^2$

Hence, the total amount of paper that will be needed to cover the wall is 396 in².
