Do parenthesis first (4)
Then, do the division 8/2 = 4
Then multiply 4 and 4 which will be 16
Add 6 to 16 and you get 22

The combined area of a pair of congruent rectangles can be represented, in square units, by the expression 18y^2-818y 2 −8. The

sveta [45]

Answer:

$Perimeter = 12y$

Step-by-step explanation:

Given

$Area = 18y^2 - 8$ -- two rectangles

Required

Determine the perimeter of one of the rectangles

First, calculate the area (A) of 1 rectangle

$A =\frac{1}{2}Area$

$A =\frac{1}{2}(18y^2 - 8)$

$A =9y^2 - 4$

Express as difference of two squares

$A =(3y - 2)(3y+2)$

Area is calculated as:

$A = Length * Width$

So, by comparison:

$Length = 3y - 2$

$Width = 3y + 2$

The perimeter is:

$Perimeter = 2 *(Length + Width)$

$Perimeter = 2 *(3y-2+3y+2)$

Collect Like Terms

$Perimeter = 2 *(3y+3y-2+2)$

$Perimeter = 2 *(6y)$

$Perimeter = 12y$

An experiment is completed where a coin is flipped and a six-sided die (singular for dice) is rolled. The outcomes from the expe

victus00 [196]

Answer:

1) $16\frac{2}{3}$ % or 20%

Step-by-step explanation:

Given that:

An experiment which is carried out by flipping a coin and rolling six sided die.

The outcomes can be:

{H1, H2, H3, H5, H6, T1, T1, T2, T3, T5}

As per question statement:

Number of outcomes having tails and an odd number greater than one is 2 (i.e. T3 and T5)

Total number of outcomes here is 10.

Therefore, to find the percentage, we use the following formula:

$\dfrac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\times 100$

$\Rightarrow \dfrac{2}{10}\times 100 = 20\%$

As per question statement, the answer is 20%.

If we consider all the outcomes, i.e.

{H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6}

Total number of outcomes = 12

The percentage will come out be :

$\Rightarrow \dfrac{2}{12}\times 100 = 16\frac{2}{3}\%$

Answer:

$20$ ft

Step-by-step explanation:

We know that the height of the object and the height of the shadow it casts are proportional. Therefore, if we let the length of the tree be $x$ , we can set up the following proportion to solve for it:

$\frac{5}{8}=\frac{x}{32}$

Solving for $x$ , we get:

$\frac{5}{8}=\frac{x}{32}$

$8*x=5*32$ (Cross-Products Property)

$8x=160$ (Simplify)

$\frac{8x}{8}=\frac{160}{8}$ (Divide both sides of the equation by 8 to get rid of $x$ 's coefficient)

$x=20$ (Simplify)

Therefore, the tree is $20$ ft tall. Hope this helps!
