60 cars to 24 cars what is the decrease percentage​

Mathematics
1 answer:
Kamila [148]3 years ago
8 0

Answer:

It decreased 60%

Step-by-step explanation:

TO figure this out we must first find 1% of 60

60/100 = .6

Now we find the difference between 60 and 24

60 - 24 = 36

Now that we know how much it decreased we must now find out what percent 36 is of 60.

.6 x 60 = 36

So 36 out of 60 is 60%

So it decreased 60%

Between x=2 and x=3, which function has a greater average rate of change than f(x)=2^x has?
maxonik [38]

Answer: f(3)

Step-by-step explanation:

First find the formula for the rate of change by taking the derivative of 2^x. Let f(x) equal some hypothetical y-value, then take the natural log of both sides.

y=2^x\\\ln(y)=x \ln(2)

Implicitly differentiate the left side and take the derivative of the right side

\frac{y'}{y} =\ln(2)

Multiply both sides by 'y' which was defined as 2^x

y'=\ln(2)*2^x

Plug in x = 2 and x = 3 to see which slope is larger

y'=\ln(2)*2^2=4\ln(2)\\y'=\ln(2)*2^3=8\ln(2)

Answer:

<h2><em><u>x = 52</u></em></h2>

Step-by-step explanation:

<em><u>Known:</u></em>

What to find = x

Exterior angle = 142

Right angle = 90

<em><u>Unknown:</u></em>

what unknown value is = ?

Interior angle = ?

<em><u>1. Find the angle of the interior angles.</u></em>

180 - 142 = 38

<em><u>2. Add the two known angles</u></em>

38 + 90 = 128

<em><u>3. Subtract from 180</u></em>

180 - 128 = 52

<h2><em><u>x = 52 is the answer.</u></em></h2>

Hope this helped,

Four times a number minus twice another number is -8. The sum of the two number is 19.Find the numbers
grigory [225]
1. To solve this exercise, you must make a system of equations.

 2. You have that f<span>our times a number minus twice another number is -8:
</span>
 4x-2y=-8

 3. And t<span>he sum of the two number is 19:
</span>
 x+y=19

 4. As you can see, you have two equations:

 4x-2y=-8   (i)
 x+y=19     (ii)

 5. Let's clear the "x" from the equation (ii):

 x=19-y

 6. Now, you need to susbtitute x=19-y into the equation (i):

 4x-2y=-8
 4(19-y)-2y=-8
 76-4y-2y=-8
 76-6y=-8
 -6y=-8-76
 -6y=-84
 y=-84/-6
 y=14

 7. You must susbstitute y=14 into the equation (ii) and clear "x":

 x+y=19
 x+14=19
 x=19-14
 x=5

 The answer is: 5 and 14
