If paper was £1.99 a pack and is now £3.98 a pack, what is the percentage increase in the price of the product?

spayn [35]

Answer:

100%

Step-by-step explanation:

The initial price of the paper = 1.99

The final price of the pack of paper = 3.98

We need to find the percentage increase in the price of the product. It can be solved as follows :

$\%=\dfrac{3.98-1.99}{1.99}\times 100\\\\=100\%$

So, the percentage increase in the price of the product is 100%.

Frank ate 12 pieces of pizza and Dave ate 15 pieces. “I ate

kobusy [5.1K]

Answer:

Frank

Step-by-step explanation:

So If Dave ate ¼ more than Frank, you would need to divide the denominator by the amount of pizzas, so if 12÷4 is 3 he ate three more pizzas than Frank. If we do the same for Frank, ⅕ or 15÷5=3

So the correct answer would be Frank because 12 is less than 15

My apologies if this wasnt explained very well

When the coordinates 1 1 7 3 8 0 and 2 âˆ’ 2 are joined which shape is formed 5 points group of answer choices trapezoid rectang

Hatshy [7]

the coordinates (1,1), (7,3), (8,0) and (2,-2) are joined which shape is formed as Square

When the coordinates (1,1), (7,3), (8,0) and (2,-2) are joined, a square is formed. The sides are equal length and the angles are all 90 degrees.The coordinates (1,1), (7,3), (8,0) and (2,-2) are points on a two-dimensional plane. When the points are connected, a square is formed. A square is a four sided shape with four 90 degree angles and four equal length sides. The length of each side can be calculated by finding the distance between the two points. For example, the distance between (1,1) and (7,3) is 6 units. Therefore, the length of each side of the square is 6 units.

babymother [125]

$\frac{1}{10}$ part of the whole painting is gold colored.

<u>Solution:</u>

Given that , In art class, Arthur has created a triangle painting $\frac{1}{5}$ of his painting is purple.

He decided he wants to Paint $\frac{4}{8}$ of the purple area gold

We have to find what fraction of the whole painting will be painting?

Now, $\frac{1}{5}$ part of whole painting is purple

And, $\frac{4}{8}$ part of the purple area is gold ⇒ $\frac{4}{8}$ part of the $\frac{1}{5}$ part of whole painting is gold

$\text { Then, fraction of gold color }=\frac{4}{8} \times \frac{1}{5}=\frac{1}{2} \times \frac{1}{5}=\frac{1}{10}$

Hence, $\frac{1}{10}$ part of the whole painting is gold colored.
