After two bites, the weight of the hamburger is recorded at 160g.

Each bite removes 20% of the burger's total weight, so to uncover the weight prior to the bites, we calculate it based on the percentage that remains.

The initial weight stands at 160g. Given that 20% of the weight was lost during a bite, we should divide this weight by the remaining percentage after the bite:

100 - 20 = 80

After a bite, 80% of the burger is what remains. Convert this percentage into a decimal by dividing it by 100:

80 \div 100 = 0.8

Now, let's divide the original weight by this figure:

160 \div 0.8 = 200

Before the second bite, the weight of the hamburger was 200g.

The same method will apply for the first bite. Initially, it weighed 200g, with 80% still intact after the initial bite. Since 80% converts to 0.8 in decimal form, divide 200 by 0.8:

200 \div 0.8 = 250

Thus, the original weight of the hamburger prior to any bites was 250 grams.

Leona [12618]

Respuesta:

3m = -3

Desglose paso a paso:

Nos dan la ecuación

2m - 6 = 8m,

por lo que

2m - 8m = 6,

-6m = 6,

m = 6/(-6),

m = -1.

Así, 3m = -3.

A special shape is 2.02 m long and 1.22 m wide. A double row of tiles makes a border . Each tile is 2cm by 2cm. How many tiles a
Svet_ta [12734]

Response:

6.48

Detailed explanation:

The calculation required to determine the number of tiles for the border is presented below:-

= 2 \times (length + breadth)

Here,

The length measures 2.02 m

And the width is 1.22

Substituting these dimensions into the formula provided above

Consequently, the total number of tiles necessary to create the border is

= 2 \times (2.02 + 1.22)

= 2 \times 3.24

= 6.48

Hence, to find the tiles required for the border, we utilized the aforementioned formula.

Which is true regarding the graphed function f(x)?
AnnZ [12381]

Explanation:

Hello! Please remember to formulate complete questions to receive accurate answers. I will assume that the depicted function derives from:

f(x)=\left(x-4\right)^{2}+5

This describes the equation of a parabola that opens upwards, with its vertex positioned at:

V(4,5)

The graph below illustrates this function. What is true about the graphed function f(x)?

  • It is accurate that the domain consists of all real numbers, as this is a polynomial function.

  • It is also correct that the range includes all real numbers where y ≥ 5

  • It is indeed true that this parabola opens upwards

  • It is valid to say it does not intersect the x-axis
