According to the given information, quadrilateral RECT is a rectangle. By the definition of a rectangle, all four angles measure 90°. Segment ER is parallel to segment CT and ______________ by the Converse of the Same-Side Interior Angles Theorem. Quadrilateral RECT is then a parallelogram by definition of a parallelogram. Now, construct diagonals ET and CR. Because RECT is a parallelogram, opposite sides are congruent. Therefore, one can say that segment ER is congruent to segment CT. Segment TR is congruent to itself by the Reflexive Property of Equality. The Side-Angle-Side (SAS) Theorem says triangle ERT is congruent to triangle CTR. And because corresponding parts of congruent triangles are congruent (CPCTC), diagonals ET and CR are congruent.

Total cousins = 12

Fraction of cousins that are girls = 6/9

So, total number of cousins that are girls
= 6/9 of 12
= 6/9 × 12
= 8

So, Maria has 8 female cousins.

S=2πr^2+2πrh
Solve for h

Answers

h = [S / (2πr)] - r

Further explanation

It is a case about two-variable linear equations and we have to solve the equation to get the variable h.

Our main plan is to isolate the variable h alone at the end of the process on one side of the equation until the variable will be equal to the value on the opposite side.

$\boxed{S = 2 \pi r^2 + 2 \pi rh}$

We can set it to be like this, i.e., just swapping positions on both sides but not changing the signs.

$\boxed{2 \pi r^2 + 2 \pi rh = S}$

We subtract both sides with $\boxed{2 \pi r^2}$ .

$\boxed{2 \pi r^2 + 2 \pi rh - 2 \pi r^2 = S - 2 \pi r^2}$

$\boxed{2 \pi rh = S - 2 \pi r^2}$

We divide both sides with $\boxed{2 \pi r}$

$\boxed{(2 \pi rh)/(2 \pi r) = (S - 2 \pi r^2)/(2 \pi r)}$

$\boxed{h = (S)/(2 \pi r) - (2 \pi r^2)/(2 \pi r)}$

We get the results as follows: $\boxed{\boxed{h= (S)/(2 \pi r) - r}}$

- - - - - - -

Let's check again from the beginning.

For example, r = 2 and h = 3, then we first calculate the value of S by using the initial equation.

$\boxed{S=2 \pi (2)^2 + 2 \pi (2)(3)}$

$\boxed{S = 8 \pi + 12 \pi }$

$\boxed{\boxed{S= 20 \pi}}$

Then, we substitute the results of S (with r = 2) into the new equation that we have compiled with h as the subject.

$\boxed{h =(20 \pi)/(2 \pi (2)) - 2}$

$\boxed{h = 5 - 2}$

We get the value h = 3 and it means that the equation has been proven.

Notes:

The formula that we discussed above is a formula for calculating the surface area of a closed cylinder.

$\boxed{S = 2 \pi r^2 + 2 \pi rh}$

Keywords: S=2πr^2+2πrh, solve for h, subtract, divide, subject, to isolate the variable h alone, two-variable linear equations

Final answer:

To solve for 'h' in the equation S = 2πr^2 + 2πrh, subtract 2πr^2 from both sides, divide by 2πr, simplifying the right side of the equation.

Explanation:

To solve for h in the equation S = 2πr^2 + 2πrh:

Start by subtracting 2πr^2 from both sides of the equation to isolate the term containing h.
This gives us 2πrh = S - 2πr^2.
To solve for h, divide both sides of the equation by 2πr.
The final step is to simplify the right side of the equation, giving us h = (S - 2πr^2) / (2πr).

(7x-y=7
(x+2y=6 estimate the solution to the system of equations

Answers

Answer:

x=4/3; y=7/3

Step-by-step explanation:

x+2y=6,

x=6-2y.

7(6-2y)-y=7,

42-14y-y=7,

15y=35,

y=7/3.

x+2y=6,

x+2*7/3=6

x=4/3

∴x=4/3, y=7/3.

Final answer:

To estimate the solution to the system of equations (7x-y=7) and (x+2y=6), we can use the method of substitution. The estimated solution is x = 1.46 and y = 2.27.

Explanation:

To estimate the solution to the system of equations (7x-y=7) and (x+2y=6), we can use the method of substitution. We can solve one equation for one variable and substitute it into the other equation. Let's solve the second equation for x: x = 6 - 2y.

Substituting this value of x into the first equation, we get:

7(6 - 2y) - y = 7

42 - 14y - y = 7

41 - 15y = 7

-15y = 7 - 41

-15y = -34

y = -34 / -15

y = 2.27

Now, substitute this value of y back into the second equation to find x:

x + 2(2.27) = 6

x + 4.54 = 6

x = 6 - 4.54
