if x varies directly as y, and y=6 when x=27, find x when y=2

Answers

Answer 1

Answer:

x = 9

Step-by-step explanation:

Given y varies directly as y then the equation relating them is

x = ky ← k is the constant of variation

To find k use the condition y = 6 when x = 27

27 = 6k ( divide both sides by 6 )

4.5 = k

x = 4.5y ← equation of variation

When y = 2 , then

x = 4.5 × 2 = 9

Answer:

=36cm^2

Step-by-step explanation:

6-12=6 (total cm of the bases for triangle B and C)

6/2= 3 (base of B and C trialngleis 3  )

Triangle formula: bh 1/2

(base)b= 3cm

height(h)=4

Formula: (3)(4) 1/2

=12 1/2

=6cm^2

^ area of 1 triangle

There are 2, so

6*2=12cm^2 (area of triangles )

Area of rectangle: L*W

4*6=24cm^2

Total area of trapezoid

=24cm^2+12cm^2

Sonu had ₹25.50. He bought one pen for ₹17.75. How much money does he

have now?


PLS WRITE STEP BY STEP EXPLAINTION​

Answers

Answer:

He has $7.75 left.

Step-by-step explanation:

To solve this problem you must subtract $25.50 by $17.75 because he bought the pen for 17.75 which is being taken away from his amount of money to start with ($25.50).

Step by step solving the subtraction problem:

$25.50-$17.50 = $7.75

So 25.50 - 17.75 you would need to make the 0 become a ten and then subtract 10 and 5, then you bring down the 5 from ($25.50) and make it 14 and subract 14 and 7. Then bring down the other 5 and make it 14 as well and subract 14 by 7 which is 7. Finally make the 2 a 1 and it will end up being 1-1 which is zero. So the answer will end up being $7.75. Hope that helps. Sorry that this answer took long for it to be posted.

Rani deposited AED 12000 for 3 years at the rate of 5 percent per annum. Calculate the simple interest and amount at the end of the 3rd year

Answers

Answer:

the principal and the amount is 1,800 and 13,800 respectively

Step-by-step explanation:

The computation of the simple interest and amount for the end of the 3rd year is shown below:

Simple interest is

= Principal × rate of interest × time period

= 12,000 × 5% × 3 years

= 1,800

Now the amount is

= 12,000 + 1,800

= 13,800

hence, the principal and the amount is 1,800 and 13,800 respectively

Find the equation of the exponential function represented by the table below:

0.025
3 0.0125

Answers

Answer:

The exponential equation is;

y = 0.1•0.5^x

Step-by-step explanation:

Here, we want to get the exponential function represented by the table

Mathematically, the general form of an exponential function is;

y = a•b^x

By getting a and b, we have the exponential function

We can use any of the points;

Let us start with (0,0.1)

0.1 = a•b^0

anything raised to zero is 1

0.1 = a * 1

a = 0.1

Now, we have a

Let us work with the second point to get b

The point is (1,0.05)

0.05 = 0.1•b^1

0.05 = 0.1b

b = 0.05/0.1

b = 0.5

Thus, we have the equation as;

y = 0.1•0.5^x

What values of x solve x 2 - 4x + 3

Answers

Answer:

x=1 and x=3

Step-by-step explanation:

When you factor it you get (x-1) and (x-3) then you subtract the 1 and 3 to the other side which is why the answer is positive.  

Answer:

x = 1, x = 3

Step-by-step explanation:

Equate the expression to zero, that is

x² - 4x + 3 = 0 ← in standard form

(x - 1)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 3 = 0 ⇒ x = 3

What is scale factor?

Scale factor is the ratio of original dimensions to the scaled dimensions.

Given is that Eiffel Tower is 986 feet tall. Caroline built a scale model that is 6 inches tall.

We can write the scale factor as -

{k} = 986/6

{k} = 164.4

Therefore, the scale factor used is {k} = 164.4.

what is the slope of the line represented by the equation y =7 - x?

Answers

Answer:

slope = -1

Step-by-step explanation:

When you put the equation into slope-intercept form (y=mx+b), where m is the slope of the line, you can see that -1 is the slope.

The slope of the line represented by the given equation is -1.

Given the following equation:

[tex]y =7 - x[/tex]    ...equation 1.

To determine the slope of the line represented by the given equation:

Mathematically, the standard form of an equation of line is given by the formula;

[tex]y=mx+b[/tex]   ....equation 2.

Where:

x and y are the points.m is the slope.b is the intercept.

Equating the two equations, we have:

[tex]y = mx+b = 7-x[/tex]

Comparing eqn 1 and eqn 2, we can deduce that the slope is -1.
