Answer:

K = 76.6089 m²

Step-by-step explanation:

A = C = 81.5983 °

B = D = 98.4017 °

a = 8.8 m

p = 11.5 m

q = 13.3233 m

h = 8.70556 m

P = 35.2 m

K = 76.6089 m^2

a = side lengths

p and q diagonal lengths

h = height

A, B, C, D = corner angles

K = area

P = perimeter

π = pi = 3.14159

√ = square root

anastassius [24]

Answer:

The fraction of one pound of cheese to be used in each sandwich is 1/8

Step-by-step explanation:

Here, we have a question that requires the method of dealing with the division of fractions.

To divide a fraction by a whole number, we multiply the denominator of the fraction by the whole number as follows;

$\frac{x}{y} \div z =\frac{x}{y\times z}$

Quantity of cheese Shane has = 1/2 pound

Number of sandwiches to be made = 4

Amount of cheese per sandwich = 1/2÷4 = 1/8.

Find the indicated limit, if it exists. limit of f of x as x approaches 9 where f of x equals x plus 9 when x is less than 9 and

SVEN [57.7K]

Answer:

B. 18

Step-by-step explanation:

For the function

$f(x)=\left\{\begin{array}{l}x+9,\ \ x$

we can find the value of the function for all x that are very close to 9 but are less than 9 and for all values of x that are very close to 9 but are greater than 9.

1. For $x$

$\lim \limits_{x\rightarrow 9}f(x)=\lim \limits_{x\rightarrow 9}(x+9)=9+9=18$

2. For $x\ge 9:$

$\lim \limits_{x\rightarrow 9}f(x)=\lim \limits_{x\rightarrow 9}(27-x)=27-9=18$

So, limit exists and is equal to 18.

Answer:

side A is 18.75 cm² greater than side B

Step-by-step explanation:

area of A = 12.5 x 7.5 = 93.75 cm²

area of B = 10 x 7.5 = 75 cm²

93.75 - 75 = 18.75 cm²
