Egal loggers got away with 4 acres of trees at a reserve in central Mexico. That number represents a 97 percent decline from two years prior. How many acres of trees did the illegal loggers get away with two years prior? Round the answer to the nearest acre.

Answers

Answer: with 133.33 acres of trees

Step-by-step explanation:

4 acres of trees, is a 97% decrease of the previous amount.

This means that if the previous amount was X, then 4 acres is 3% (or 0.03 in decimal form) of X, or:

4 acres = 0.03*X

Now we can solve this for X as:

X = 4acres/0.03 = 133.33 acres

The illegal loggers got away with 133.33 acres of trees

solve this equation fast please

Answers

I don’t think there’s a solution
Ok hi so I’m going to help you solve on this equation, if I solved this correctly can you please mark me as brainiest? I’d really appreciate it. Anyway let’s get started!

What we need to do is cancel both like terms on both sides of this equation which is
8=8 and you remove them.

Then you are left with -2y-3y=-5y-12

What you need to do is add -2y-3y because they are like terms

Now you have -5y

Then you put -5y=-5y-12

So you have to now cancel equal terms on both sides of this equation which were “-5y=-5y”, then you turn them into a 0

Now you are left with 0=-12

Therefore the statement is false for any value of y.

HELP PLZ TEXT MESSAGE: The cost of a text message increases from $0.10 per messages to $0.25 per message. What is the percent increase in the cost of sending a text message?​

Answers

x = number of text messages sent

0.2x+40=50

0.2x = 10

5(0.2x) = 5(10)

x = 50

Answers

Answer:

C) 140

Step-by-step explanation:

We can see from the diagram that mMEF + mDEM = mDEF because they share the same lines.

Therefore:

69x + 2 + 34 = 2 + 86x

Now we can solve this equation.

First we can eliminate the +2 from each side as they will cancel:

69x + 34 = 86X

And then rearrange to solve for x:

34 + 69x - 69x = 86x - 69x

34 = 17x

34/17 = 17x/17

x = 2

Now that we have the value for x, we can substitute it into the original equation:

mMEF = 69(2) +2

mMEF = 138 + 2

mMEF = 140

Therefore the correct answer is C) 140.

Hope this helped!

Answers

Answer:

Step-by-step explanation:

1.Based on the equation the y-intercept is -2(go down 2 places on the y axis)

2.Since here is only x in the equation the rise over run will be 1/-1 (go up 1 and to the left 1 from the point -2 on the y axis) keep doing that all the way down the graph marking your points, also reverse the process going down 1 and to the right 1 to mark the points on the opposite side.

3.Draw the line through the points you marked from step 2

4.In the equation it is x-2 so it is a positive slope and a negative y-intercept

Answers

Step-by-step explanation:

5t-3(7t+1) < 93

Remove the parentheses

5t-21t-3 < 93

-16t < 93+3

-16t < 96

Divide both sides by 16

-t<96/16

-t<6

t > -6

Answer: The inequality t < 6 is the correct answer.

Step-by-step explanation:

5t - 3 (7t + 1) < 93​ <--- This is the original equation.

5t + (7t + 1) - 3 < 93​ <---- Use commutative property.

16t - 3 < 93 <--- Simplify

16t - 3 + 3  < 93​ + 3 <---- Add 3 to both sides,

16t < 96 <--- Simplify and do addition.

[tex]\frac{16t}{16}[/tex] < [tex]\frac{96}{16}[/tex] <--- Divide both sides by 16.

t < 6 <--- is the answer to the inequality.

A cork has a mass of 3 grams and a volume of 16 cm3

Answer:

0.1875, or 3/16

Step-by-step explanation:

The formula for density is mass/volume.

I hope this helps :)

Answer:

[tex]{\boxed {\sf \frac{3}{16} \ g/cm^3}}[/tex]

or

[tex]\boxed {\sf 0.1875 \ g/cm^3}}[/tex]

Step-by-step explanation:

Density can be found by dividing the mass by the volume.

[tex]\rho= \frac{m}{v}[/tex]

The mass of the cork is 3 grams and the volume is 16 cubic centimeters.

[tex]m= 3 \ g\\v= 16 \ cm^3[/tex]

Substitute the values into the formula.

[tex]\rho = \frac{3 \ g }{16 \ cm^3}[/tex]

Divide.

[tex]\rho=\frac {3}{16} \ g/cm^3[/tex]

[tex]\rho=0.1875 \ g/cm^3[/tex]

The density of the cork is 3/16 or 0.1875 grams per cubic centimeter.

7. The lifetime of a certain brand of tires is approximately normally distributed, with a

mean of 40,000 miles and a standard deviation of 2,500 miles under normal driving conditions.

Tire wear is greatly affected by road, weather and driver conditions along with proper

maintenance of the tires. A driver who aggressively accelerates or makes quick stops, for

example, will wear out a tire much more quickly. The brand carries a warranty of 33,000 miles

under normal driving conditions, i.e., the company will replace a tire if it wears out before this

mileage limit is reached.

Answers

Answer:

0.0025551

Step-by-step explanation:

Given that:

Mean (m) = 40000

Standard deviation (s) = 2500

P(x < 33,000) :

USing the relation to obtain the standardized score (Z) :

Z = (x - m) / s

Z = (33000 - 40000) / 2500 = - 2.8

p(Z < -2.8) = 0.0025551 ( Z probability calculator)

Probability of Tyre wagering out before mileage limit is reached = 0.0025551

Two years ago Juanita bought 2 shirts for $15 and last year she bought 4 shirts for $45. Assuming the prices will increase linearly, how much will 8 shirts cost Juanita this year?

Answers

Answer:

This year, Juanita will have to use $75.

Step-by-step explanation:

Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.
