The current average property value is two-sevenths more than last year’s average value. What was last year’s average property va
Ilya [14]

Answer:

63350

Step-by-step explanation:

Given that the current average property value is two-sevenths more than last year’s average value.

Let x be the last year's average property

Then we have as per the given information this year property value

=x+\frac{2}{7} x

Equate this to

x+\frac{2}{7} x=81450\\9x = 7(81450)\\x = 7(9050)\\x= 63350

Korolek [52]

Answer:

I thought that all races were = I thought it was fine we all loved each other and that there were protests. That the black lives matter. if a police officer kills a white man bc the white man is a threat then no one cares but if a police man kills a black man bc a black man is a threat everyone protests. I thought we were = but then black people are out there saying there lives matter. They do but white lives matter too so do blue lives and green lives and purple lives. Everyone matters but if you say that apparently you get in trouble. All lives matter but instead people had to make a program titled black lives matter.

A rectangle initially has dimensions 6 cm by 7 cm. All sides begin increasing in length at a rate of 1 cm/s. At what rate is the
Morgarella [4.7K]

Answer:

  49 cm²/s

Step-by-step explanation:

The problem statement tells you what to do.

Write an equation relating A, b, h:

  A = bh . . . . . . the equation for the area of a rectangle

Differentiate with respect to t:

  dA/dt = (db/dt)h + b(dh/dt) . . . . . . . product rule

To find the rate of change after 18 seconds, you need to know the dimensions b and h after 18 seconds. Since each dimension was increasing at the rate of 1 cm/s, it is 18 cm more than it was at the beginning:

At 18 seconds,

  b = 6 cm + 18 cm = 24 cm;

  h = 7 cm + 18 cm = 25 cm.

Of course, db/dt = dh/dt = 1 cm/s. Then the rate of change of area is ...

  dA/dt = (1 cm/s)(25 cm) + (24 cm)(1 cm/s)

  dA/dt = 49 cm²/s

_____

You could write a formula for the area as a function of time and differentiate that:

  A = (6 +t)(7 +t) = 42 + 13t + t²

Then the derivative is ...

  dA/dt = 13 +2t

and when t=18, this is ...

  dA/dt = 13 + 2(18) = 49 . . . . cm²/s
