In a warehouse, a group of identical robots fills orders. In 10 minutes, 5 robots can fill 20 orders. If 8 robots worked at that

Alexxandr [17]

Answer:

192 orders

Step-by-step explanation:

All robots are working simultaneously, so each robot takes 10 minutes to do their orders. They are all identical, so they take an equal amount of time to do each order, meaning 20 ÷ 5 = 4. Each robot takes 10 minutes to do 4 orders.

If there are eight robots working for 60 minutes, each robot can make six times as many orders, compared to when they were working for 10 minutes. 4 x 6 = 24. There are eight robots, so 24 x 8 = 192 orders.

Find the shorter base of a trapezoid if the trapezoid's area is 52, its altitude is 8, and its longer basis 10.

DiKsa [7]

Answer:

The shorter base is 3

Step-by-step explanation:

$a = \frac{(b1 + b2)}{2} \times h$

$52 = \frac{(10 + b2)}{2} \times 8$

$b2 = 3$

If you are on a ship at sea navigating to a point that is 300 miles north and 400 miles west, find the distance from tour ship t

s344n2d4d5 [400]

Answer:

$\huge \boxed{\mathrm{500 \ miles}}$

Step-by-step explanation:

A right triangle is formed.

300 miles and 400 miles are the legs of the triangle.

We can apply Pythagorean theorem.

$c=\sqrt{300^2 +400^2 }$

$c=\sqrt{90000 +160000}$

$c=\sqrt{250000}$

$c=500$

The house has a form of a rectangle with one side two and a half times as long as the other side. a Construct the expression for

Nookie1986 [14]

Answer: $A=2.5x^{2}$

Step-by-step explanation:

1. Let's write the following formula for calculate the area of a rectangle:

$A=yx$

Where $y$ is the lenght (the longer side) and $x$ is the width (the shorter side).

2. You know that the length is 2.5 times as long as the other side, which indicates a multiplication. Then:

$y=2.5x$

3. So, you must substitute $y$ into the equation for calculate the area of the rectangle and then you must simplify.

4. Then, you obtain the following expression:

$A=(2.5x)(x)\\A=2.5x^{2}$
