can someone help please i don’t understand this.

Length of Simon's tent = 6 feet

Distance from the bottom of the tent to the tent's base = 8 feet

Let the length of rope be R.

The tent and the rope forms a right angle triangle where the rope is the hypotenuse.

We know that :

[tex]\color{hotpink} \tt{hypotenuse}^{2} \color{plum}= {base}^{2} + {height}^{2} [/tex]

Which means :

[tex] = \tt {R}^{2} = {6}^{2} + {8}^{2} [/tex]

[tex] =\tt {R}^{2} = 36 + 64[/tex]

[tex] = \tt {R}^{2} = 100[/tex]

[tex] =\tt R = \sqrt{100} [/tex]

[tex]\hookrightarrow\color{plum}\tt \bold{R = 10 \: feet}[/tex]

Thus, the hypotenuse of this triangle = 10 feet

▪︎Therefore, the length of the rope = 10 feet

Answer:

About 0.6548 grams will be remaining.  

Step-by-step explanation:

We can write an exponential function to model the situation. The standard exponential function is:

[tex]f(t)=a(r)^t[/tex]

The original sample contained 510 grams. So, a = 510.

Each half-life, the amount decreases by half. So, r = 1/2.

For t, since one half-life occurs every 38 days, we can substitute t/38 for t, where t is the time in days.

Therefore, our function is:

[tex]\displaystyle f(t)=510\Big(\frac{1}{2}\Big)^{t/38}[/tex]

One year has 365 days.

Therefore, the amount remaining after one year will be:

[tex]\displaystyle f(365)=510\Big(\frac{1}{2}\Big)^{365/38}\approx0.6548[/tex]

About 0.6548 grams will be remaining.  

Alternatively, we can use the standard exponential growth/decay function modeled by:

[tex]f(t)=Ce^{kt}[/tex]

The starting sample is 510. So, C = 510.

After one half-life (38 days), the remaining amount will be 255. Therefore:

[tex]255=510e^{38k}[/tex]

Solving for k:

[tex]\displaystyle \frac{1}{2}=e^{38k}\Rightarrow k=\frac{1}{38}\ln\Big(\frac{1}{2}\Big)[/tex]

Thus, our function is:

[tex]f(t)=510e^{t\ln(.5)/38}[/tex]

Then after one year or 365 days, the amount remaining will be about:

[tex]f(365)=510e^{365\ln(.5)/38}\approx 0.6548[/tex]

the range is the difference between the greatest value and the smallest one. The greatest value in the data set is 33, and the smallest is 24.

So u just subtract 24 from 33:

33 – 24 = 9

Answer:

Yes

Step-by-step explanation:

They can because the sum of two Angles is 180, and if they are both 90, they add up to 180, making them congruent.  Hope this helps

Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. 

Saying this you should probably infer that if 2 Angles are complementary, then they are 90°.

Meaning you would need 2 pairs of complementary angles to have a supplementary angle (180°).

Step-by-step explanation:

To get the area of a right triangle (a triangle with an angle of 90 [represented by the box in the corner]) you have the formula of

Area = (a*b) divided by 2

a = one side of the triangle

b = another side of the triangle

Neither side are the hypotenuse.

Given:

Mark took 2 hours to make a jacket.

The jacket was made up of 50 kilograms of wool.

To find:

The time in which Mark use 500 kilograms of wool for the jackets.

Solution:

We have,

1 jacket take 2 hours.

Number of jackets in 50 kg of wool = 1

Number of jackets in 1 kg of wool = [tex]\dfrac{1}{50}[/tex]

Number of jackets in 500 kg of wool = [tex]\dfrac{1}{50}\times 500[/tex]

                                                              = [tex]10[/tex] Jackets

Time taken by 1 jacket = 2 hours

Time taken by 10 jacket = 20 hours

Therefore, it will take 20 hours to use 500 kilograms of wool for the jackets.

Answer:

20 hours

Step-by-step explanation:

1 jacket=50kg wool

1 jacket= 2hrs

500kg available/50kg per jacket= 10 jackets

10 jackets x 2hrs per jacket=20hrs
