Step-by-step explanation:

Each side would be 60. 60/3 would be 20. So x = 20

Answer:

x = 20

Step-by-step explanation:

Looking at the image you've posted here. We can see this triangle is equilateral. That also means 3x is 60°, as are the other two angles. All you really have to do is dividing both sides of the equation by 3 to get x to equal 20.

A house cost $185,500 in 2000. By the year 2015, the value was $132,000. What was the growth
rate as a percent for that 15-year period?

Answers

Answer:

their was no growth rate it lost 53,500 in those 15 years at a rate of about 3,566 a year

Step-by-step explanation:

The growth rate is the percentage increase and it is the increase with respect to the original thus growth rate will be 28.84%.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

The cost in 2000 is $185500

Cost in 2015 is $132000

Change or increase = (185500  - 132000)

% increase = change/original

% increase = (185500  - 132000)/185500 = 28.84%

Hence "The growth rate is the percentage increase and it is the increase with respect to the original thus growth rate will be 28.84%".

6) Pardeep has a rectangular sheet of paper of size 44cm x 20cm. He rolled it
along its breadth and a cylinder is formed. Find volume of the cylinder.​

Answers

Answer:

[tex]V=1398.4\ cm^3[/tex]

Step-by-step explanation:

Given that,

Pardeep has a rectangular sheet of paper of size 44cm x 20cm. He rolled it  along its breadth and a cylinder is formed.

When he rolled it  along its breadth, 20 is equal to circumference i.e.

20 = 2πr

r is radius of base of cylinder

r = 3.18 cm

44 cm will be height of the cylinder.

The volume of the cylinder is given by :

[tex]V=\pi r^2 h\\\\V=\dfrac{22}{7}\times (3.18)^2 \times 44\\\\V=1398.4\ cm^3[/tex]

So, the volume of the cylinder is [tex]1398.4\ cm^3[/tex].

A calculator is required to obtain the final answer on this question. A solid metal sphere at room temperature 20oC is dropped into a container of boiling water (100oC). If the temperature of the sphere increases 10o in 9 seconds, find the temperature of the ball after 18 seconds in the boiling water. (Assume the sphere obeys Newton's Law of Cooling.)

Answers

Answer:

38.71°C

Step-by-step explanation:

Given :

Initial temp, T0 = 20°C

Final temperature, T = 20 + 10 = 30°C

Time, t = 9 seconds

Surrounding temperature, Ts = 100°C

Newton's Law of cooling :

T = Ts + (T0 - Ts) * e^-kt

Obtain the value of k

30 = 100 + (20 - 100) * e^-9k

30 - 100 = - 80e^-9k

-70 = - 80e^-9k

-70 / - 80 = e^-9k

0.875 = e^-9k

Take the In of both sides

In(0.875) = - 9k

−0.133531 = - 9k

k = 0.133531 / 9

k = 0.0148

Hence,

t = 18

T = Ts + (T0 - Ts) * e^-kt

T = 100 + (20 - 100) * e^-0.0148(18)

T = 100 - 80 * e^-0.0148(18)

T = 100 - 80 * 0.7661326

T = 38.709392

T = 38.71°C

Ram obtains 40% of the marks in a paper of 200 marks. Shyam is ahead of Ram by 25% of Ram' s marks, while Bhuvan is ahead of Shyam by one month of his own marks. How many marks does Bhuvan get?​

Answers

Answer:

First, we start with:

"Ram obtains 40% of the marks in a paper of 200 marks"

In this case, 200 marks represent the 100%

Then how much is the 40%?

we have the relations:

40% = X

100% = 200 marks

Now we can take the quotient of both equations:

(40%/100%) = X/200marks

(40%/100%)*200marks = X = 80 marks

So Ram obtained 80 marks.

Now we have:

"Shyam is ahead of Ram by 25% of Ram's marks"

Now the 100% is the number of marks that Ram has, this is:

100% = 80 marks

And Shyam has 25% more than that, then we have:

125% = X

Same as before, we take the quotient of both equations:

(125%/100%) = X/80 marks

1.25*80 marks = 100 marks.

Shyam has 100 marks.

The last part is (this is not written correctly, it says "one month", it should be "one-ninth")

"while Bhuvan is ahead of Shyam by one-ninth of his own marks."

if his own marks are X, we have the equation

X = 100 + (1/9)*X

X - 1/9*X = 100

X*(8/9) = 100

X = (9/8)*100 = 112.5

So Bhuvan has 112.5 marks

Terms/CoefficientsCoordinates (x, y)Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

4x - 3y = -20

-x - 8y = 5

Step 2: Rewrite Systems

-x - 8y = 5

[Addition Property of Equality] Add 8y on both sides:                                   -x = 8y + 5[Division Property of Equality] Divide -1 on both sides:                                 x = -8y - 5

Step 3: Redefine Systems

4x - 3y = -20

x = -8y - 5

Step 4: Solve for y

Substitution

Substitute in x:                                                                                                  4(-8y - 5) - 3y = -20[Distributive Property] Distribute 4:                                                                 -32y - 20 - 3y = -20Combine like terms:                                                                                         -35y - 20 = -20[Addition Property of Equality] Add 20 on both sides:                                  -35y = 0[Division Property of Equality] Divide -35 on both sides:                              y = 0

Step 5: Solve for x

Define original equation:                                                                                 -x - 8y = 5Substitute in y:                                                                                                  -x - 8(0) = 5Multiply:                                                                                                             -x = 5[Division Property of Equality] Divide -1 on both sides:                                 x = -5

Answer:

x = -5

y = 0

Step-by-step explanation:

4x-3y=-20

-x-8y=5  then x = 8y-5

substitute for x

4(8y-5)-3y = -20

32y-20-3y = -20

29y = 0

y = 0

4x-0 = -20

x = -5
