A train accelerates at 2.2 m/s^2. With an initial velocity of 22 m/s, what will be the velocity of the train after 19 s

Answers

Answer 1

[tex]a=2.2[\frac{m}{s^2}]\\v_0=22[\frac{m}{s}]\\t=19[s]\\\\a = \frac{\Delta v}{t}\\\Delta v=at=41.8[\frac{m}{s}]\\v = v_0+\Delta v=63.8[\frac{m}{s}][/tex]

Answer: The velocity will be 63.8 m/s.

Rodrigo and Melissa went to the art supply store to buy drawing materials. Rodrigo bought 10
pencils and 7 felt-tip markers for a total of $19.00. Melissa bought 3 pencils and 5 felt-tip markers
for a total of $10.05. Which of the following systems of equations could be used to determine
the cost of one pencil, P, and one felt-tip marker, m?

Answers

Answer:

10P + 7m = 19 .......... 1

3P + 5m = 10.05 .......... 2

Step-by-step explanation:

Let the cost of pencil be represented by P, and felt-tip by m. So that;

Rodrigo bought 10 pencils and 7 felt-tip at the cost of $19.0.

⇒ 10P + 7m = 19 .......... 1

Melissa bought 3 pencils and 5 felt-tip at the cost of $10.05.

⇒ 3P + 5m = 10.05 .......... 2

From equations 1 and 2,

10P + 7m = 19 .......... 1

3P + 5m = 10.05 .......... 2

Multiply equation 1 by 3, and 2 by 10 to have;

30P + 21m = 57 ......... 3

30P + 50m = 100.5 ....... 4

Subtract equation 3 from 4,

30P - 30P + 50m - 21m = 100.5 - 57

29m =43.5

m = [tex]\frac{43.5}{29}[/tex]

 = 1.5

m = 1.5

Substitute the value of m in equation 2,

3P + 5m = 10.05 .......... 2

3P + 5(1.5) = 10.05

3P = 7.5 = 10.05

3P = 3

P = 1.0

Thus, the cost of a pencil is $1.0 and that of a felt-tip is $1.5.

Amelia runs a catering business. Based on her records, her weekly profit can be modeled by P=-2x^2+152x-150P=−2x 2 +152x−150, where xx is the number of meals she caters and PP is her profit.

Answers

Answer:

The least number of meals Amelia needs to cater in order to begin making profit = 38 meals.

Step-by-step explanation:

Given - Amelia runs a catering business. Based on her records, her weekly  

            profit can be modeled by P= -2x² + 152x - 150, where x is the  

            number of meals she caters and P is her profit. When P is negative,  

            Amelia losses money.

To find - What is the least number of meals Amelia needs to cater in order  

              to begin making profit.

Proof -

As given, P = -2x² + 152x - 150

Now,

Above the break-even point, she only get profit

The break -even point is a point where there is no profit, and no loss.

Now,

For break-even point,

[tex]\frac{dP}{dx} = 0[/tex]

⇒[tex]\frac{d}{dx}( -2x^{2} + 152x - 150) = 0[/tex]

⇒-4x + 152 = 0

⇒- 4x = - 152

⇒4x = 152

⇒x = [tex]\frac{152}{4}[/tex] = 38

∴ we get

If Amelia caters at least 38 meals , then she makes Profit.

The mass of Parcel A was 0.7 kg. Parcel B was heavier than Parcel A.
Parcel C had the same mass as Parcel B. The total mass of the three
parcels was 2.5 kg. What was the mass of Parcel C?​

Answers

Answer: 0.9kg

Step-by-step explanation:

Since we are informed that Parcel C had the same mass as Parcel B, let their mass be represented by x.

Therefore,

Parcel A + Parcel B + Parcel C = 2.5

0.7 + x + x = 2.5

0.7 + 2x = 2.5

2x = 2.5 - 0.7

2x = 1.8

x = 1.8/2

x = 0.9

The mass of parcel C is 0.9kg
