Let's say that the value of a car over time is given by the equation:
y = 20,000 (.88)
Tell me the following two things:
a) Is this a growth or decay problem and why?
b) What is the percent amount that the value changes by each year?

Let's Say That The Value Of A Car Over Time Is Given By The Equation:y = 20,000 (.88)Tell Me The Following

Answers

Answer 1

Answer:

Step-by-step explanation:

So bascially decay means shrinks or shrivels. Growth means like growing, bigger, sort of like a happy plant :D.

To find if this is getting bigger or is shrinking, lets plug in something simple like 1 for the time(t). Sooo:

20,000*.88^1

Since its a 1 exponent it does nothing so:

20,000*.88

Now this is 17600 you can use calculator but if you do this in head like me all I did is multiply 88 by 2 which was simply since 8 times 2 is 16 so 160+16 is 176 then I added zeros:

y=17600

As we can see this is smaller than 20,000, so it is a decaying problem.

By what percent tho.

Well this is pretty easy to reconize once you understand where to find it.

When they talk about percentage, they mean how much it decreased by.

This is 100%-the multiplyied value.

In this case the multiplyed value is 0.88, sooo:

100%-88%=18%

So the percent amount that the value decreased by is 18%.

Hope this helps!

Sandy has a total of 35 coins in her money jar. If Sandy's jar contains only nickels and dimes and the value ol
the coins is $2.50, how many nickels does Sandy have?

Answers

you'll have to solve simultaneously

let nickel be x, dime be y

x + y = 35 ... ( 1 )

5x + 10 y = 250
5 ( x + 2y ) = 250
x + 2y = 50 ... ( 2 )

in ( 1 )
x = 35 - y ( 3 )

sub ( 3 ) into ( 2 )
( 35 - y ) + 2y = 50
y = 15

sub y into ( 1 )
x + y = 35
x + 15 = 35
x = 20

therefore, Sandy has 20 nickels and 15 dimes

The answer is 15.01

First you need to find the other angle of the triangle so you do 90+25 which gives you 115 and subtract that by 180 because all angles of a triangle add up to 180. That gives you 65 then you will use TAN(65) and get 2.144506920509559 which you will then multiple by 7 to get 15.01154844356691 which you then round to get 15.01!

Step-by-step explanation:

Angle 7 and the one marked 38° form a linear pair. The fact that line L exists and is parallel to line M is irrelevant to this question. Angles of a linear pair are supplementary, so ...

  ∠7 = 180° -38° = 142°

Additional comment

Because lines L and M are parallel, all of the obtuse angles in this geometry have the same measure as angle 7. Likewise, all of the acute angles are congruent to 38°.

  ∠1 = ∠3 = ∠5 = ∠7 = 142°

prisim a and prisim b have the same volume. which could be the dimensions of prisim b?​

Answers

Answer:

length = 4 feet

width = 4 feet

height = 10 feet

Step-by-step explanation:

8x4x5 = 160

4x4x10 = 160

Answer:

length = 4 feet

width = 4 feet

height = 10 feet

Step-by-step explanation:

First we must find the volume of prism A

Assuming that the prism is a rectangular prism we can easily calculate the volume by multiplying the length by the width by the height

So V = 8 * 4 * 5

8 * 4 = 32

32 * 5 = 160

Hence, the volume of prism a is 160ft²

The question states that the volume of prism A is  the same as the volume of prism B. Given that information we want to find the possible dimensions of prism B such that volume of prism A = volume of prism B.

We can do this by find the volume of each answer choice ( again, assuming that their rectangular prism )

For the first answer choice

4 * 4 * 10 = 160

160 = 160 however lets check the other answer choices.

For the second answer choice:

5 * 4 * 7 = 140

140≠160 therefore the second answer choice is not correct

For the third answer choice

8 * 4 * 6 = 192

192 ≠ 160 therefore the third answer choice is not correct

For the fourth answer choice

I can't see the dimensions, however we already know that the answer is the first answer choice.
