Answer:

  • System is given below

Step-by-step explanation:

  • Let (applicable to all three lines below)
  • Hard candy = x kg with price $1.60/kg
  • Gummy worms = y kg with price $2.20/kg
  • Total weight = 50 kg with mixed price $1.75/kg

<u>Required equations:</u>

  • x + y = 50                        total weight
  • 1.60x + 2.20y = 50*1.75      total price

=========================================

<u><em>Note</em></u><em>. It says don't solve but the solution below for those who is interested to know the answer.</em>

<u>Simplify the second equation and solve by substitution x = 50 - y:</u>

  • 1.6(50 - y) + 2.2y = 87.5
  • 80 - 1.6y +2.2y = 87.5
  • 0.6y = 7.5
  • y = 7.5/0.6
  • y = 12.5

<u>Find the value of x:</u>

  • x = 50 - 12.5 = 37.5

<u>Hard candy</u> = 37.5 kg and <u>gummy worms</u> = 12.5 kg

Answer:

The most suitable experimental simulation to find the probability of getting the six toys is by rolling the dice and recording the occurrences.

Step-by-step explanation:

As there are a total of 6 different dinosaurs, the probability of each of them is given as

P(X=one dinosaur)=1/6

In order to design an experiment, as the data is completely random and unknown, thus the experiment is designed such that the probability of individual option is 1/6.

In this regard the most suitable option is rolling a dice, numerous times and recording the occurrences accordingly.

A parachutist descends 44 feet in 4 seconds. Express the rate of the parachutist's change in height as a unit rate.
Montano1993 [528]

The unit rate of the parachutist change in height is 11 feet per second.

   • In Mathematics, Unitary method is a technique for solving a question by first finding the value of a single unit and then finding the required value by multiplying the number by value of single unit .

   • We use unitary method to find the ratio of one thing with respect to other thing.

   • There are two types of unitary method one is Direct Variation and the other is Inverse variation.

We have the rate of descend as 44 feet in 4 sec.

So, in 1 second it will be = 44 / 4 = 11 feet.

Which is the unit rate.

Therefore, the unit rate of descend for the parachutist is 11 feet per second.
