Answer:

the value of 532×13=6,916

The graph can be seen at the end, and by looking at it, you can see that a solution can be (10, 0).

y ≥ (-1/2)*x + 2 + 1/2

y < (1/5)*x + 6

To graph it, first we need to graph the lines:

y = (-1/2)*x + 2 + 1/2

y = (1/5)*x + 6

Once you have this, we analyze each inequality.

y ≥ (-1/2)*x + 2 + 1/2

Because we use the symbol ≥ we need to use a solid line and we need to shade the region above the line.

For y < (1/5)*x + 6 we need to use a dashed line (the symbol < implies that the points on the line are not solutions) and we need to shade the region below the line.

Then the solution of the system is given by the intersection of the shaded region.

For example, a solution can be the point (10, 0), which you can see that belongs to that region.

Alexandra and Chi compete in an​ Olympic-type triathlon consisting of a 1.5 km ​swim, a 40 km bicycle​ ride, and a 10 km run. There are two transitions in the race where the participants take time to change from one mode of the race to another. Their times from the race are shown. Complete questions 1dash4 below.

How long does it take Alexandra to complete the triathlon. Write a linear equation to model total time t in hours.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

SWIM:

Alexandra __5km/hr

Chi _______ 6km/hr

Transition 1:

Alexandra __ 4 minutes

Chi _______ 5 minutes

CYCLE:

Alexandra __15km/hr

Chi _______ 15km/hr

Transition 2:

Alexandra __ 3 minutes

Chi _______ 5 minutes

RUN:

Alexandra __6km/hr

Chi _______ 7.5km/hr

Distances:

swim distance = 1.5km

bicycle​ ride distance = 40km

run distance = 10km

Time taken by Alexandra :

time = distance / speed

Swim time = 1.5km / 5km/hr = 0.3 hr

Transition 1 = 4/60 = 0.067 hr

Cycle time = 40km / 15km/hr = 2.67 hours

Transition 2 = 3/60 = 0.05 hr

Run time = 10 / 6km/hr = 1.67 hrs

Total time(t) in hours taken by Alexandra :

(0.3 + 0.067 + 2.67 + 0.05 + 1.67) hrs = 4.757 hours

Time taken by Chi :

time = distance / speed

Swim time = 1.5km / 6km/hr = 0.25 hr

Transition 1 = 5/60 = 0.083 hr

Cycle time = 40km / 15km/hr = 2.67 hours

Transition 2 = 5/60 = 0.083 hr

Run time = 10 / 7.5km/hr = 1.33 hrs

Total time(t) in hours taken by Chi

(0.25 + 0.083 + 2.67 + 0.083 + 1.33) hrs = 4.757 hours = 4.416 hours

Answer:

396 males

Step-by-step explanation:

First, let's find the percentage of males who took part in the survey.

Now, let's find 55% of 720.

Step 1: Multiply 55 by 720

Step 2: Divide 39,600 by 100.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

The number of males took part in the survey is 396.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, 720 students took part in the survey.

Only 45% were female.

So, the number of females = 45% of 720

= 45/100 ×720

= 0.45×720

= 324

So, number of males = 720-324

= 396

Therefore, the number of males took part in the survey is 396.

Answer:

Step-by-step explanation:

The expression that is equivalent to [tex]\sqrt{\frac{2x^{5} }{18} }[/tex] is [tex]x^{2} \frac{\sqrt{x} }{3}[/tex].

The given expression is [tex]\sqrt{\frac{2x^{5} }{18} }[/tex].

We can write the above expression as [tex]\sqrt{\frac{2.x^{2} .x^{2} .x}{2*9} }[/tex]

The square root of [tex]x^{2}[/tex] i.e. [tex]\sqrt{x^{2} } =x[/tex] and same for [tex]\sqrt{9} =3[/tex].

So, we can write the expression [tex]\sqrt{\frac{2.x^{2} .x^{2} .x}{2*9} }[/tex] as [tex]\frac{x.x\sqrt{x} }{3}[/tex].

So, [tex]\frac{x.x\sqrt{x} }{3}= x^{2} \frac{\sqrt{x} }{3}[/tex].

Therefore, the expression that is equivalent to [tex]\sqrt{\frac{2x^{5} }{18} }[/tex] is [tex]x^{2} \frac{\sqrt{x} }{3}[/tex].

Hence,

The value which is expected for the number of heads when a coin is flipped twice is 1. The value of a, b, and c is 0.25, 0.50, and 0.25 respectively.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

The 4-column 2 rows table which shows the number of heads and probability of that is shown below.                    

Heads                       0                1              2

Probability.                a               b             c

When a coin is flipped two times, then we get the four outcomes. The sample space for flipping a coin twice is,

[tex]{HH, HT,TH, TT}[/tex]

Here, the H represent the head and T represent the tail. Only one time in four events there is no head appear. In this sample space, the probability of 0 heads both the time is,

[tex]P_0=\dfrac{1}{4}=0.25[/tex]

The 1 head appears twice in the sample space (HT, TH). Thus, the probability of 1 heads both the time is,

[tex]P_1=\dfrac{2}{4}=0.50[/tex]

On both flip, head appears a single time in the sample space (HH). Thus, the probability of 2 heads both the time is,

[tex]P_2=\dfrac{1}{4}=0.25[/tex]

The new table for these values is attached below.

Hence, the value which is expected for the number of heads when a coin is flipped twice is 1. The value of a, b, and c is 0.25, 0.50, and 0.25 respectively.

Answer:

21000

Step-by-step explanation:

You move the decimal point over that many times as the power of 10.

IT is found that [tex]2.1 \times 10^4[/tex] can be written in standard form as 21,000.

Since Scientific notations have some of the profits are Better readability due to compact representation

The value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.

To convert from scientific notation to standard form, we simply move the decimal point to the right by the number of places indicated by the exponent (4 in this case).

Starting with  [tex]2.1 \times 10^4[/tex] , we move the decimal point four places to the right to get 21,000.

Hence,   [tex]2.1 \times 10^4[/tex] in standard form is 21,000.

S=2000n+100000

Step-by-step explanation:

Since Nicole will have a salary of $110000 after working 5 years for the company, we know that S = 110000 when n = 5.  

         Find the slope using the two points.

           110000 - 100000            10000

   m =  ------------------------     =      ----------   =   2000

Enzo can only buy 21 kiwis from the store.

Step-by-step explanation:

We have to divide

But since it's going too be hard for me to show you the long division, I'm just going to use a multiplication trick!

Let's find what is 20x0.99 first, because I feel like this CAN be the answer.

20x0.99=19.8

So this is not the answer

Now, let's try 22x0.99

22x0.99=21.78

So this is also not the answer.

Now, let's try 21, I think only this one can be the answer.

21x0.99=20.79

Step-by-step explanation:

The energy that it takes to melt 2 kg of ice is; (2 kg * 1000 g/kg) * 1 mol/18.02 g * 6.03 kJ/mol = 669 kJ

We are given;

Mass of ice; m = 2 kg

Now, from tables showing constants for ice, we see that;

Molar heat of fusion for ice; Δ_fus.H = 6.03 kJ/mol at 0°C.

Molar mass of Ice which is water is; 18.02 g/mol

Formula to get the energy is;

E = (m/M) * Δ_fus.H

E = (2 kg * 1000 g/kg) * 1 mol/18.02 g * 6.03 kJ/mol = 669 kJ
