Answer:

Option B is correct.

the average cost in 1990 is, $12,841

Step-by-step explanation:

Given the equation :

y = 12841(1.01)^x          ....[1]

where y represents the he average cost of an education at a private college after 1990 and x be the time in years.

We have to find the average cost in 1990.

⇒x = 0

Substitute in [1] we have;

y = 12841(1.01)^0

Simplify:

y =\$12,841

Therefore, the average cost in 1990 is, $12,841

Tapiwa takes 5% more leaves than adam raked. together they raked 697 liters of leaves
Nina [5.8K]
----------------------------------
Define their percentage:
----------------------------------
Adam = 100%
Tapiwa = 100 + 5 = 105%

----------------------------------
Find their total percentage:
----------------------------------
100 + 105 = 205

----------------------------------
Find 1%
----------------------------------
205% = 697 liters
1% = 3.4 liters

----------------------------------
Find 100% (Adam):
----------------------------------
100% = 3.4 x 100
100% = 340 liters

----------------------------------
Find 105% (Tapiwa):
----------------------------------
105% = 3.4 x 105 
105% = 357 liters

--------------------------------------------------------------------
Answer: Tapiwa =  357 liters and Adam = 340 liters.

Jenna bought two more pairs of jeans. If both of them are blue, what percentage of her jeans is blue now? If both of them are no
Sergeeva-Olga [200]
What you must keep in mind is that there are 4 jeans in total, which represents 100%
 When she bought two jeans, we have the following information:
 If both of them are blue:
 50% of their jeans is blue now, that is:
 x = (50/100) * 4 = 2
 2 jeans are blue.
 This means that she did NOT have 2 blue jeans before.
 Thus:
 If they are not blue: 
 We have 4 jeans that are not blue.
 Then, 0% of her jeans is blue now
 answer:
 0% percentage of her jeans is blue now

Find x <br> Plz help me !!!
mel-nik [20]

Answer:

\Huge\boxed{x=33.2}

Step-by-step explanation:

Hello there!

We can solve for x using law of sines

As we can see in the image a side length divided by sin ( its opposite angle) = a different side length divided by sin ( its opposite angle)

So we can use this equation to solve for x

\frac{21}{sin(35)} =\frac{x}{sin(65)}

Our objective is to isolate the variable using inverse operations so to get rid of sin (65) we multiply each side by sin (65)

\frac{x}{sin(65)} sin(65)=x\\\\\frac{21}{sin(35)} sin(65)=\frac{21sin(65)}{sin(35)}

we're left with

x=\frac{21sin(65)}{sin(35)}\\x=33.18208755

assuming we have to round the answer would be 33.18 or 33.2

Find the distance between each pair of points E(-1, 0),F(12, 0)
Olegator [25]

Answer:

The answer is

<h2>13 \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\ </h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

E(-1, 0) and F(12, 0)

The distance between them is

<h3>|EF|  =  \sqrt{ ({ - 1 - 12})^{2}  +  ({0 - 0})^{2} }  \\  =  \sqrt{ ({ - 13})^{2} }  \\  =  \sqrt{169}</h3>

We have the final answer as

<h3>|EF| = 13 \:  \: units</h3>

Hope this helps you
