Answers

Answer 1

Answer: This is a very easy question. All required information's are alreadypresent in the question. It only needs step by step procedure toultimately find the value of n. Now let us look into the given equation.
-8n + 4(1 + 5n) = -6n -14
-8n + 4 + 20n = -6n - 14
12n + 4 = -6n -14
12n + 6n = -14 - 4
18n = -18
n = - 18/18
= -1
So the value of n in the given equation is -1.

Answers

you need to divide the amount by the number of days to find the price per day so
Jay paid $126 for 4 days
$126/4=$31.50 per day
and
Stephanie paid $184.50 for 6 days
$184.50/6=$30.75
So
The answer is
C. Stephanie paid the lower daily rate of $30.75.

Answers

Answer:

A. 24+24+120+160+200

Step-by-step explanation:

Surface area of the triangular prism= addition of the area of each shape that forms the prism

There are two triangles

Area of a triangle=1/2*base*height

=1/2*8*6

=1/2*48

=24

Area of two triangles=24+24

There are 3 rectangles with different dimensions

Back rectangle=length×width

=20×6

=120

Bottom rectangle=length ×width

=20x8

=160

Top rectangle=length × width

=20×10

=200

Surface area =Area of two triangles + Back rectangle + Bottom rectangle + Top rectangle

=24+24+120+160+200

A: 24+24+120+160+200 :)

A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 666 centimeters per minute. After 202020 minutes, the water level is 220220220 centimeters. Graph the relationship between the pool's water level (in centimeters) and time (in minutes).

Answers

Answer:

$y=6x+100$

The graph is drawn below.

Step-by-step explanation:

Let the minutes passed be $x$ and height of water level be $y$ cm.

Given:

Rate of rise of water level, $m = 6\textrm{ cm/min}$

When $x=20\textrm{ min},y=220\textrm{ cm}$

Therefore, the relationship can be expressed using the point-slope form of an equation if a line.

The point-slope form is given as:

$y-y_(1)=m(x-x_(1))$

Here, $m=6,x_(1)=20,y_(1)=220$

Therefore, the relationship is given as:

$y-220=6(x-20)\ny-220=6x-120\ny=6x-120+220\ny=6x+100$

Therefore, the relationship between the pool's water level (in centimeters) and time (in minutes) is $y=6x+100$ .

The graph is shown below.
