Answer:

Area = 64 + 16\pi

Step-by-step explanation:

Given

See attachment for the heart created

Required

The area of the heart

The area of the heart is the sum of the area of the square and the areas of the two semicircles.

From the attachment, we have:

s = 8in --- length of the square

d = 8in --- diameter of each semicircle

Calculate radius

r = 0.5 * d

r = 0.5 * 8 = 4in

The area of the square is:

Area = Length^2

A_1 = 8^2

A_1 = 64in^2

The area of the two semicircles is:

A_2 =2 * \frac{\pi r^2}{2} i.e. 2 multiplied by the area of 1

A_2 = \pi r^2

A_2 = \pi *4^2

A_2 = \pi *16

A_2 = 16\pi

So, the area of the heart is:

Area = A_1 + A_2

Area = 64 + 16\pi

two chefs are trying to break world record for the longest spaghetti. chef a measures his spaghetti strand to be 503 2/3 ft chef
zhuklara [117]
Lenght spaghetti chef a:
503 2/3ft= (503*3+2)/3=1511/3 =503,(6)
lenght spaghetti chef b:
503,66

Because 503,(6)>503,66
=> lenght spaghetti chef a > lenght spaghetti chef b
So, the winner must be chef a, but, if 503.66 rounds to 503.7, also 503(6) rounds to 503.7, and in this case
lenght spaghetti chef a= lenght spaghetti chef b
So, <span>chef a should protest the judges' decision, because his </span>lenght spaghetti is ≥ lenght spaghetti chef b.

¿cual es el perimetro total de un paralelogramo obicuo cuya base mide 2∛54x² cm , y cuyo lado oblicuo mide 3∛54x²?
Step2247 [10]

Answer:

p=10\sqrt[3]{54}x^2

Step-by-step explanation:

We are given parallelogram

Since, two opposite sides of any parallelogram are always equal

Let's assume first side =a

second side =b

so, we get

a=2\sqrt[3]{54}x^2

b=3\sqrt[3]{54}x^2

now, we can find perimeter

perimeter=2a+2b

so, we get

p=2(2\sqrt[3]{54}x^2)+2(3\sqrt[3]{54}x^2)

we can simplify it

p=4\sqrt[3]{54}x^2+6\sqrt[3]{54}x^2

p=10\sqrt[3]{54}x^2................Answer

The probability that you roll a 3 on a six-sided die is . The probability that you flip a coin that lands on tails is . The prob
aivan3 [116]

Answer:

1/6; 1/2; 1/12; P(T|3) = 1/2; therefore, events are independent because P(T|3) = P(T).

Step-by-step explanation:

The probability of rolling a 3 on a six-sided die is 1/6.  This is because there is one 3 out of 6 possibilities.

The probability of flipping a coin on tails is 1/2.  This is because there is one side "tails" out of 2 possibilities.

The probability of rolling a 3 and flipping tails is 1/6(1/2) = 1/12.

P(T|3) = P(3 and Tails)/P(3) = 1/12 / (1/6) = 1/12(6/1) = 6/12 = 1/2

Since P(T|3) = P(3), these are independent events.
