Answer:

92400m

Step-by-step explanation:

<em>Find the volume of the two rectangles.</em>

Volume of a rectangle: length*width*height

The first, larger rectangle: 64*60*28=107520m

The second, smaller rectangle: 18*30*28=15120m

<em>Subtract the two rectangles' volumes for the building's total volume.</em>

107520-15120=92400m

1) Una bicicleta circula en línea recta a una
erica [24]

Answer:

the distance covered is 11.25 km

Step-by-step explanation:

Given that

The speed of the bicycle is 15 km/h

And, the time taken of the bicycle is 45 minutes

We need to determine the distance covered

As we know that

Speed = Distance ÷ Time

So, distance = Speed × time

= 15 km /h × 0.75 hours

= 11.25 km

The 0.75 hours come from

= 45 minutes ÷ 60 minutes

= 0.75 hours

Hence, the distance covered is 11.25 km

Solve for y: -2(5y-1)-y=-4(y-3)
Talja [164]

Answer:

<h2>y =  -  \frac{10}{7}</h2>

Step-by-step explanation:

- 2(5y - 1) - y = - 4(y - 3)

Expand the terms in the bracket

That's

-10y + 2 - y = - 4y + 12

Group like terms

Send the constants to the right side of the equation and those with variables to the left side

That's

- 10y - y + 4y = 12 - 2

- 7y = 10

Divide both sides by - 7

We have the final answer as

<h3>y =  -  \frac{10}{7}</h3>

Hope this helps you
