The volume of Tyler's shoe box is 144 cubic inch

From the question, we are to calculate the volume of the shoe box.

From the given information, we have that

Tyler is filling the shoe box with cubes that are each 1 cubic inch.

and

He found out that 48 of the 1 cubic inch cube completely fills the bottom of the box

Also,

He observed that he can put 2 more layers of cubes in the box.

Thus,

The number of 1 cubic inch cube that would completely fill the box is

48 + (2×48)

= 48 + 96

= 144 cubes

Since the cubes are 1 cubic inch each,

Then,

The volume of the shoe box = 144 × 1 cubic inch

Volume of the shoe box = 144 cubic inch

Hence, the volume of Tyler's shoe box is 144 cubic inch

The side length of Amanda's phone is 8 inches.

A scale drawing is either an enlarged or reduced image of another image or object. A scale drawing is enlarged or reduced using a scale. A scale is a used to determine the ratio between the scale drawing and the original diagram.

The scale is used to keep the proportion of the dimensions between the scale drawing and the original diagram similar. The scale in this diagram is 7inches to 1 inches. This means that the screen on the wall is 7 times larger than her phone's screen.

In order to determine the side length of Amanda's phone, divide the scale of the screen by the side length of the screen on the wall.

Side length of Amanda's phone = 56 inches / 7 inches

The area of shaded region is calculated as: 112.5 cm².

The area of the shaded region in the diagram above is:

Area of shaded region = area of rectangle - area of triangle = (length)(width) - 1/2(base)(height).

Given the following:

Length of rectangle = 20 cm

Width of the rectangle = 9 cm

Base of triangle = 20 - 3 - 2 = 15 cm

Height of triangle = 9 cm

Plug in the values into the equation, area = (length)(width) - 1/2(base)(height):

Area of shaded region = (20)(9) - 1/2(15)(9)

Area of shaded region = 180 - 67.5

The net change between the indicated points is -1 and the average net change is  - 0 . 75 .

The difference between the two f(x) values is the net change.

The ratio between the net change and the change between the two input values is used to calculate average net change or average rate of change. The average rate of change can be calculated using the same two points and the formula: f(b)-f(a) / b-a .

The two given points on the graph are (1,4) and (5,1)

The net change is given by the change in the y -coordinates of the graph .

Δy = y₂ - y₁

Here y₂ = 1

and y₁ = 4

Therefore Δy = y₂ - y₁ or, Δy = 1 - 4 = - 3

Hence the net change is -3 units.

Now the average net change is calculate by the change in y divided by the change in x.

average net change  = Δy ÷ Δ x

again , average net change = -3 ÷ ( 5 - 1 ) = - 0 . 75

The average net change for the function is  - 0 . 75

As per the question statement, a point J (5,3) is rotated 90° counterclockwise around the origin.

We are required to determine the coordinates of the resulting point J'.

To solve this question, we need to follow a rule of cartesian coordinate geometry which is, "If a point (x, y) is rotated 90° counterclockwise around the origin, then the coordinates of the new point lie on (y, -x).

Answer:

Step-by-step explanation:

From 2 minutes to 5 minutes the pump puts in (200-110) = 90 gallons ...in 3 minutes....so the rate of the pump is    30 gal / min

   at two minutes the pump has put in 30 x 2 = 60 gallons......so there was 50 gallons in the tank to start ( 50 + 60 = 110)

the equation becomes :

   G = 50  +  30 t    

               where t = minutes

   and 50 is the initial volume in the tank

For 13 minutes      G = 50 + 30 (13) = 440 gallons

For 890 gallons      890 = 50 + 30 t

                                840 = 30 t

                                   t = 28  minutes

t intercept occurs when  G = 0

                         0 = 50 + 30 t

                             t = - 5/3   minute    <====this is the amount of time before measurements were taken.....or the time for the pump put in 50 gallons before the  start

Answer:

y = -5x + 10

Step-by-step explanation:

Answer:

-5x + 10

Step-by-step explanation:

If a line 2 is perpendicular to line 1 and line 1 has slope m, then line 2 must have slope = [tex]\sf -\dfrac{1}{m}[/tex] which is the negative of the reciprocal of m

Essentially the product of the two slopes = -1

The line
[tex]y = \dfrac{1}{5}x - 19[/tex]
has slope of  [tex]\dfrac{1}{5}[/tex] so the slope of line h which is perpendicular to this line must have slope = negative of reciprocal of [tex]\dfrac{1}{5}[/tex]

Reciprocal of [tex]\dfrac{1}{5}[/tex] is 5
Negative of reciprocal is thus -5

Equation of h is of the form
y = -5x + b where b is the y intercept, the value of y at x = 0

Since line h passes through (3, 0) we plug in these values for x and y and solve for b
0 = -5(3) + b

0 = -15 + b
15 = b                  (Adding 15 on both sides)
b = 15

Equation of line h is y = -5x + 15

Line g is parallel to line h. Parallel lines have the same slope so the equation for line g is
y = -5x + b                     (since slope of g = slope of h = -5)

Since this line passes through x = -1, y = 15 we can solve for b as before by plugging these values into the equation

15 = -5(-1) + b
15 = 5 + b
10 = b         (Subtracting 5 on both sides)
b = 10

So equation of line g = -5x + 10
