A pet store owner, Byron, needs to determine how much food he needs to feed the animals. Byron knows that he needs to order the same amount of bird food as hamster food. He needs four times as much dog food as bird food and needs half the amount of cat food as dog food. If Byron orders 600 packages of animal food, how much dog food does he buy? Let b represent the number of packages of bird food Byron purchased for the pet store.

Answers

Answer:

300 bags of dog food

Step-by-step explanation:

4b + 2b + b + b = 600

(dog) + (cat) + (bird) + (hamster) = 600

8b = 600

b = 75

Byron purchased 75 bags of bird food. He needs 4 times that of dog food. So, he purchased 300 bags of dog food.

Answer:

[tex]\sqrt{10}[/tex]

Step-by-step explanation:

This is a 45-45-90 triangle whose leg to hypotenuse ratio is 1 / [tex]\sqrt{2}[/tex]

so I set up a proportion of 1 / [tex]\sqrt{2}[/tex] = x / 2 [tex]\sqrt{5}[/tex]

cross-multiply to get [tex]\sqrt{2}[/tex]x = 2[tex]\sqrt{5}[/tex]

x = 2[tex]\sqrt{5}[/tex] / [tex]\sqrt{2}[/tex] and multiply numerator and denominator by [tex]\sqrt{2}[/tex], this is called rationalizing the denominator

lets do

[tex]\\ \sf\longmapsto \sqrt{2}x=2\sqrt{5}[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{2\sqrt{5}}{\sqrt{2}}[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{2}\sqrt{5}[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{2(5)}[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{10}[/tex]

Two flag poles at Liberty Park are 27 feet tall. The distance from the top of one flag pole to the base of the other is 45 feet. What is the distance between the two flag poles?

Answers

Answer:

Step-by-step explanation:

Answer:

The distance between the two poles is 36 feet.

Step-by-step explanation:

If 2 flag poles are 27 feet tall each

if the distance from one flag pole to the base of the other flag pole is 45 feet, this forms the shape of a right angle triangle.

Here, we are going to make use of the Pythagoras theorem.

a2 + b2 = c2

27 2 + b2 = 45 2

b2 = 45 2 - 27 2

b = 45 2 - 27 2 (square root)

b = 2025 - 729

b= 1296 (square root)

b = 36

PLS HELP- Richard and Teo have a combined age of 33. Richard is 15 years older than twice Teo's age. How old are Richard and Teo?

Answers

Answer:

Teo= 9

Richard= 24

Step-by-step explanation:

x= Richard

y= Teo

33-15= 18

18÷2= 9

15+9=24

Teo is 6 years old and Richard is 27 years old.

What is the equation?

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

Let x be Teo's age, then Richard's age is 15 years older than twice Teo's age, or 15 + 2x. The combined age of Richard and Teo is 33, so we can write an equation:

x + (15 + 2x) = 33

Simplifying and solving for x, we get:

3x + 15 = 33

3x = 18

x = 6

So Teo is 6 years old and Richard is 15 + 2(6) = 15 + 12 = 27 years old.
