Answer:

50 legs

Step-by-step explanation:

We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate 2(4)+4(4)+1(4)+5(4)+1(2)+3(2), right?

Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want 2(4)+4(4)+1(4)+5(4)+1(2).

We multiply it out to get 8+16+4+20+2.

We add these up to get 50.

So, our answer is \boxed{50} legs.

Gina has 6 yards of ribbon. She cuts the ribbon into pieces that each measures three fourths yard. How many pieces of three four
ziro4ka [17]

Given

Gina has 6 yards of ribbon.

She cuts the ribbon into pieces that each measures three fourths yard.

Find out  how many pieces of three fourths yard does Gina have

To proof

let the number of pieces of the ribbon be x.

As given in the question

Gina has of ribbon = 6 yards

She cuts the ribbon into pieces that each measures three fourths yard

Than the equation becomes

x\times \frac{3}{4} = 6

x = \frac{6 \times 4}{3}

solving the above equation

we get

x = 2 × 4

x = 8

Gina have 8 pieces of three fourths yard

Hence proved

Describe the set of all complex numbers that are at a distance of 2 units from the origin.
Andreyy89

Answer:

The description of the set is A = \{s\in \mathbb{C}|\|s\| = 2\}.

Step-by-step explanation:

From Complex Analysis, we remember that complex numbers are numbers whose form is:

s = a+i\, b, a,b \in \mathbb{R} (1)

Where i = \sqrt{-1}.

In addition, the distance from the origin is defined by the following Pythagorean identity:

\|s\| = \sqrt{a^{2}+b^{2}} (2)

The following condition must be satisfied:

\|s\| = 2

Then, the set of all complex numbers that are at a distance of 2 units from the origin is described below:

A = \{s\in \mathbb{C}|\|s\| = 2\} (3)

Solve for the largest value of $x$ such that $5(9x^2+9x+10) = x(9x-40).$ Express your answer as a simplified common fraction.
irinina [24]

Hello, please consider the following.

\begin{aligned}5(9x^2+9x+10) &= x(9x-40)\\&=9x^2-40x\end{aligned}\\\\ 45x^2+45x+50=9x^2-40x\\\\ (45-9)x^2+(45+40)x+50=0\\\\ 36x^2+85x+50=0

We can estimate the discriminant, and then, the solutions and we take the largest one.

\Delta=b^2-4ac=85^2-4*36*50=25=5^2\\\\x_1=\dfrac{-85-5}{2*36}=\dfrac{-18*5}{18*4}=\dfrac{-5}{4}\\\\x_2=\dfrac{-85+5}{2*36}=\dfrac{-80}{72}=\dfrac{-8*10}{8*9}=\boxed{\dfrac{-10}{9}}

Thank you
