Maddox McDonald A caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes. How fast does the caterpillar move in feet per minute? 1 3

Answers

Answer: 2/3 feet per minute

Step-by-step explanation:

From the question, we are informed that a caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes.

The rate at which the caterpillar move in feet per minute will be:

= 4 2/3 ÷ 7

= 14/3 ÷ 7

= 14/3 × 1/7

= 14/21

= 2/3 feet per minute

If 7 workers take 500 hours to finish a project, how long will it take 14 workers to complete the same project?

Answers

Answer:

250 hours

Step-by-step explanation: increasing the number of workers will make the project go faster. So they multiplied the 7 by 2 so now there are 14 workers so then the time it'll take to finish the project would be cut in half because now they have twice the numbers of workers. correct me if I'm wrong

Tristan has already taken 18 pages of notes on his own, and he will take 1 page during each
hour of class. In all, how many hours will Tristan have to spend in class before he will have
a total of 31 pages of notes in his notebook?

Answers

Make an equation
Y = 18 + 1x
y = total pages, x = hours
plug in 31 for total page
31 = 18 + 1x
Subtract 18 from both sides
x = 13
Solution: 13 hours

Which two numbers multiply to 20 and add to 9

Answers

Answer: 5x4=20

And 5+4=9

Step-by-step explanation:

The required two numbers are 4 and 5.

What is equation?

"It is a statement which consists of equal symbol between two mathematical expressions."

For given example,

We need to find two number such that if multiply then we get 20 and add to get 9.

Let 'a' and 'b' be two numbers.

According to given conditions,

a × b = 20 .........................(i)

a + b =9 .......................(ii)

So, from given conditions we have two equations (i) and (ii).

From equation (ii) we have,

a = 9 - b ...............(iii)

Substitute above value of 'a' in equation (i),

⇒ (9 - b) × b = 20

⇒ 9b - b² = 20

⇒ b² - 9b + 20 = 0

Now we solve this quadratic equation to find b.

⇒ b² - 9b + 20 = 0

⇒ b² - 5b - 4b + 20 = 0

⇒ (b - 5) (b - 4) = 0

⇒ b = 5 or b = 4

Find the value of 'a' from equation (iii)

When b = 5

⇒ a = 9 - 5

⇒ a = 4

When b = 4

⇒ a = 9 - 4

⇒ a = 5

Therefore, the required two numbers are 4 and 5.

if u see a snake what do u do?

A. run away from it
B. run towards it
C. make loud noise
D. throw stuff at the snake

Answers

run towards it and throw stuff at it

Answer: A. run away from it

The African black mamba is the fastest moving land snake at 16-20 km/h. A person—regardless of how scared they are—could easily escape and outpace that snake with no problem. In reality, there's no need to run at all. The snake won't attack you unless you provoke it (i.e., don't do what option B, C, or D suggests), and snakes are probably more scared of us than we are of them. If I could add an option, I'd add: E. Leave it alone or keep still. If it moves towards you, slowly back off, and if it moves again, keep still, and then move slowly. The snake will eventually back off unless you do something to agitate it.

Answer:

2 1/2

Step-by-step explanation:

Answer:

2 1/2

Step-by-step explanation:

Since P is at -4 and you want a number that is 6 1/2 units away from it. You are either adding 6 1/2 to it or subtracting 6 1/2 to that number.

-4 + 6 1/2 = 2 1/2

-4 - 6 1/2 = -10 1/2

Also if you count 6 and 1/2 notches in either directions from -4, you will also get both of those answers.

The multiple choice only gives you the 2 1/2 option so that is the one they are looking for.
