How do you get why by itself in this equation? 4x+5y=5

We know that, 1 litre = 1000 ml

Then, 2 litres = 2000 ml

Hence, the required ratio of 1000 ml to 2000 ml be

= 1000 : 2000

= 1 : 2

1 litres =1000ml

then

1000:2000

1:2

Answer:

Step-by-step explanation:

The answer is (C) since when we plug in (4,8) we get that

y= 1/2 x

8 = 1/2 *4

8=2, which isn't true.

Answer:

√55

Step-by-step explanation:

The geometric mean of a and b is √(ab).

The geometric mean of 5 and 11 is √(5 × 11) = √55

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is                    [tex]\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]  

Sequence is collection of  numbers with some pattern .

Given sequence

[tex]a_{1}=5\\\\a_{2}=-10\\\\\\a_{3}=20[/tex]

We can see that

[tex]\frac{a_1}{a_2}=\frac{-10}{5}=-2\\[/tex]

and

[tex]\frac{a_2}{a_3}=\frac{20}{-10}=-2\\[/tex]

Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2

Now [tex]n^{th}[/tex]  term of this Geometric progression can be written as

[tex]T_{n}= 5\times(-2)^{n-1}[/tex]

So summation of 15 terms can be written as

[tex]\sum_{n=4}^{15} T_{n}\\\\$\\$\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is                    [tex]\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]

Answer:

x = 30

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

The given is a right triangle so one of the angle is 90 degrees:

90 + 2x + x = 180 add like terms

90 + 3x = 180 subtract 90 from both sides

3x = 90 divide both sides by 3

x = 30

=======================================================

Explanation:

Line K is 9x-4y=-5*4 which is the same as 9x-4y=-20

Rule: Anything parallel to Ax+By = C is of the form Ax+By = D.

The equation 9x-4y=-20 has A = 9, B = -4 and C = -20.

That means Ax+By = D becomes 9x-4y = D.

------------------------------

Plug in the coordinates (x,y) = (4,7) and compute the value of D.

9x-4y = D

D = 9x-4y

D = 9(4)-4(7)

D = 36 - 28

D = 8

So 9x-4y = D becomes 9x-4y = 8

----------------------------

The last step is to solve for y to get the equation in y = mx+b form.

9x-4y = 8

-4y = 8-9x

-4y = -9x+8

y = (-9x+8)/(-4)

y = (-9x)/(-4) + 8/(-4)

y = (9/4)x - 2    is the slope-intercept form of line L

The equation is in y = mx+b form where,

m = 9/4 = slope

b = -2 = y intercept

Answer: There are two ways you can do this; by radians or by degrees.

Step-by-step explanation: The formula used for calculating an area of a circle's shaded region in RADIANS is: A = (θ / 2) × r^2 and θ is equivalent to radians. The second formula used for calculating an area of a circle's shaded region in DEGREES is: (θ / 360) × πr2 where θ is equivalent to degrees.

The War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30-day withdrawal period, without congressional authorization for use of military force (AUMF) or a declaration ...Step-by-step explanation:

1. K(x) = (3x)2 -x + 2 -x + 1

k(x) = g(x) ∘ h(x)

2. K(x) = 2 ^3x + 2

k(x) = g(x) × h(x)

3. K(x) = 2^x - 3x - 2

k(x) = h(x) ÷ g(x))

4. K(x) = 3(2 x) + 2

k(x) = h(x) ∘ g(x)

5. K(x) = 2^x + 3x + 2

k(x) = g(x) - h(x)

6. K(x) = 2^x(3x + 2)

k(x) = g(x) + h(x)

Answer:

  (1/2)^(t/4) = ((1/2)^(1/4))^t

Step-by-step explanation:

If time t is given in hours, then the number of 4-hour time periods is t/4. If the half-life is 4 hours, the population multiplier is ...

  (1/2)^(t/4)

Using the rules of exponents, that can be rearranged to ...

  (1/2)^((1/4)·t) = ((1/2)^(1/4))^t

That is, the multiplier every hour is ...

  (1/2)^(1/4)

The expected number of times he picks a blue marble is the mean of the blue marbles

Malik should expect to pick a blue marble 10 times when he picks 25 marbles

The given parameters are:

Blue = 16

Red = 12

Green = 12

The total number of marbles is:

Total = 16 + 12 + 12

So, we have:

Total = 40

When he picks 25 marbles, the expected number of blue marble is:

Expected = Blue/Total * 25

So, we have:

Expected = 16/40 * 25

Evaluate the product

Expected = 10

Hence, he should expect to pick a blue marble 10 times when he picks 25 marbles
