Each sheep has 4 legs and each chicken has 2 legs.if a farm boy counts 50 heads and 130 feet, how many sheep are there

Answers

Answer:

15 sheep

Step-by-step explanation:

1 leg = 1 foot

1 head = 1 animal

Suppose all the animals are chickens:

50 × 2 = 100

130 - 100 = 30

4 - 2 = 2

30 ÷ 2 = 15

Hence, there are 15 sheep.

Answers

Answer:

not a real number

Step-by-step explanation:

any negative number under a square root sign, except for 0, isn't real

On evaluating the given roots,

(a) [tex]$-(\sqrt[3]{8}) = -2$[/tex]

(b) [tex]$\sqrt[4]{-81}$[/tex] is not a real number

(a) [tex]$-(\sqrt[3]{8})$[/tex]:

The cube root of 8 is the number that, when raised to the power of 3, equals 8. In this case, the cube root of 8 is 2, because [tex]2^3 = 8[/tex].

Since we have a negative sign in front of the cube root, the result will be the negative value of the cube root of 8.

Therefore, [tex]$-(\sqrt[3]{8}) = -2$[/tex].

(b) [tex]$\sqrt[4]{-81}$[/tex]:

The fourth root of a number is the number that, when raised to the power of 4, equals the given number.

In this case, we are looking for the fourth root of -81.

However, the fourth root of a negative number is not a real number. This is because raising a positive number to an even power (in this case, 4) will always result in a positive value, and there is no real number that, when raised to the power of 4, gives a negative result.

Therefore, the fourth root of -81 is not a real number.

What 2 decimal place number lies between 4.174 and 4.189 ?

Answers

This question is a bit vague to me but I will answer it as best as I can:

Answer: 4.18

When looking at decimals, you only focus on the numbers after the “.” Point
Since the numbers are .17 approximately and .19 approximately when rounded to the nearest hundredth

We can safely .18 is in between .17 and .19
Because the integer 18 is between 17 and 19 on the real number spectrum.

Therefore 4.18 is between 4.174 and 4.189

Show all work to identify the asymptotes and zero of the function f of x equals 4 x over quantity x squared minus 16.

Answers

9514 1404 393

Answer:

asymptotes: x = ±4, y = 0zero: x = 0

Step-by-step explanation:

The function factors as ...

  [tex]f(x)=\dfrac{4x}{(x-4)(x+4)}[/tex]

The vertical asymptotes are found where the denominator factors are zero:

  x-4 = 0   ⇒   x = 4

  x+4 = 0   ⇒   x = -4

The zero of the function is where the numerator is zero:

  4x = 0   ⇒   x = 0

The horizontal asymptote of the function is the value of 4x/x² when x tends to infinity. That value is zero. The equation of the horizontal asymptote is ...

  y = 0

Quinn leaves her house at 10:00 am and runs 3 miles at a steady pace of 6 miles per
hour. She relaxes and takes a lunch break for 1 hour. She is pretty tired so she walks
home at a steady pace of 2 miles per hour. What time does Quinn return home

Answers

Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.

Velocity is distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex]

She walked 3 miles at a velocity of 6 miles per hour, thus [tex]d = 3, v = 6[/tex]. The time is:

[tex]v = \frac{d}{t}[/tex]

[tex]t = \frac{d}{v} = \frac{3}{6} = 0.5[/tex]

Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.Distance of 3 miles, velocity of 2 miles per hour, thus [tex]d = 3, v = 2[/tex]. The time she took to return, in hours, is:

[tex]t = \frac{d}{v} = \frac{3}{2} = 1.5[/tex]

1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

Write an algebraic expression that represents8 minus the quantity b divided by 6. Nico could feel that they were out there, looking in on him as if he were some sort of sideshow attraction at a carnival. He was facing his own reflection, but he knew he was actually standing on the wrong side of a two-way mirrorthey could see him, but he couldn't see them. Nico realized things were unfortunately going to stay this way, too, if he continued to remain silent.2Nico pulled away from the mirror and once again scanned the tiny room that had been his noiseless prison for days. The walls were cold and blank, and they seemed to shine with some sort of clear, icy liquid. The floor felt like rough slate on his bare feet, and it, too, was cold and clammy. The chill of the room had gotten into his bones, and every night Nico crouched, shivering in the corner, wrapped tightly in the flimsy fabric they had left for him.3In the center of the room was a steel table, bolted to the floor, with a single, bare light bulb dangling above it, just out of reach. Atop the table lay the remains of Nico's latest meal, if it could even be called that: a rock-hard crust of bread, some tepid broth, and a fatty lump of meatthe likes of which Nico had never before seen, let alone eaten. Of course, Nico hadn't touched a thing they had offered, choosing instead to take an occasional secret nibble from the protein bar he had secreted away in a hidden pocket of his uniform.4The worst part of this whole ordeal, however, wasn't the room or the food. It was the deafening silence. Nico was alone in this box with only the pounding thoughts of uncertainty in his head. He went over and over the events leading to his incarceration, and he had absolutely no answers. Where was he? How long would he be here? Who was outside, looking in?5Nico had originally come to this supposedly uninhabited globe to take rock and crust samples for the International Geologic Institute. The planet certainly appeared deserted when he and his fellow scientists first landed. Then, after getting separated from the rest of his crew, Nico made the greatest and most shocking discovery of his careerthe planet he was sent to explore was anything but deserted. It was a vibrant and very inhabited world.6That was when Nico was discovered by the alien patrols. They surrounded him, confiscated his equipment, and dumped him into this room. He was cut off from all contact whatsoever, completely isolated and alone with his thoughts.7Nico couldn't take the silence a minute longer. He had to make contact, even if it meant contact with alien life-forms. He returned to the mirror and began pounding on the inch-thick glass. Get me out of here! he bellowed. I'll tell you anything you want to know! Anything! Just get me out of here! Please... Nico slumped to the floor, and the door opened slowly. Two beings walked over to Nico, lifted him gently to the chair, and handed him a mug of sweet-smelling, warm liquid.8We are glad you are finally ready to talk to us, Mr. Nico.
