Donna has 6 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same
distance to cool down. If she runs at a speed of 10 mph and walks back at a speed of 2 mph, how long should she plan to spend walking back?

Answers

Answer 1

Answer:

Avg speed of the round trip = 2*10*2/(10+2) = 10/3 mi/hr

D = r*t = (10/3)*6 = 20 miles

--> 10 miles each way

--> 5 hours walking back.

She'll get bored doing that.

A librarian wants to spend no more than $800 on some new desks and chairs for the library. The librarian decides to spend $320 on desks.

If each chair costs $24, what is the maximum number of chairs the librarian can buy for the library and stay within the budget?

Answers

Answer:

I think 20

Step-by-step explanation:

480/24

The maximum number of chairs that the librarian can buy is 20

What are mathematics operations?

A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.

• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.

Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which :

s represents = the number of chairs,

and we simply solve for s.

800 = 320 + 24s  ... subtract both sides by 300

500 = 24s ... divide both sides by 24

20.83 = s

Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.

On the left side, we have 3 people pulling with a force of 50n. That makes the total force 150. On the right side, we have 2 people pulling with 75n force which makes the total force 150n ad well. If the force is the same on each side then the rope cannot move. If they force on one of the sides was greater than the rope would move to that side

-Hope this helps

Answer:

I would say it will move to the ( Right ) because even tho there’s more students on the left there is also more force to the right making the right side have the most force.

Step-by-step explanation: so the answer is it will move to the right because of the higher force.

Step-by-step explanation:

TO find the slope pick two points and do y2 - y1 / x2 - x1

I picked the first two:

2 - 8/ -1 - -2 = -6/ 1 = -6

The slope of the given line is - 6 as per slope-intercept form.

What is the slope of a straight line?

The linear equation y = mx + c represents the slope-intercept form of a line passing through the point (x, y).

Here, 'm' is the slope and 'c' is the y-intercept of the given line.

The slope of a line that passes through points (x₁, y₁) and (x₂, y₂) is defined as:

m = (y₂ - y₁)/(x₂ - x₁)

Therefore, the slope of a line that passes through (-2, 8) and (-1, 2) is

= (2 - 8)/[- 1 - (- 2)]

= - 6/1

= - 6

Brady's rectangle has an area of 35.52 cm^2

Staci's rectangle with area of 61.44 cm^2

So, Staci's rectangle is 61.44 -35.52 cm^2 more than Brady's.
