The ratio of collectible stamps Georgia owns to stamps that Julie owns is 2:1. Julie has 64 stamps. How will the ratio of Georgia’s stamps to Julie’s stamps change if they both sell half of their stamps? Explain.

Answers

Answer:

Step-by-step explanation:

As both are selling half of their stamps, the ratio won't change. It will be same:

Reason:

Georgia : Julie = 2 : 1

Let total stamps = x

Part of stamps that Georgia has = 2/3 of x

Part of stamps that Julie has = 1/3 of x

[tex]\frac{1}{3}x=64\\\\x = 64*3\\\\x= 192[/tex]

Total stamps = 192

Stamps with Georgia = 192 - 64 = 128

After selling half of his stamp, Georgia has  = 128÷2  = 64

After selling half of her stamp, Julie has  = 64 ÷ 2  = 32

Ratio of stamps after selling half of their stamps = 64 : 32

                              = 2 : 1

 The ratio of collectible rocks Juanita owns to rocks that Aisling owns is 3:1. Aisling has 32 rocks. How will the ratio of Juanita’s rocks to Aisling’s rocks change if they both sell one fourth of their rocks? Explain.

Juanita : Aisling = 3 : 1

Let total rocks = x

Part of rocks that Juanita has = 3/4 of x

Part of rocks that Aisling has = 1/4 of x

[tex]\frac{1}{4}x=32\\\\x = 32*4\\\\x= 128[/tex]

Total rocks = 128

Rocks with Juanita = 128 - 32 = 96

After selling one fourth of his rock, Aisling has  = 32 ÷  4 = 8

After selling half of her rock, Juanita has  = 96 ÷ 4  = 24

Ratio of rocks after selling one fourth of their rocks =24 : 8

                              = 3 : 1

Find the area under the standard normal distribution curve between z=o and z=1.47

Answers

Answer:

hheikxkhyujherik

Step-by-step explanation:

iieeokwe7ib2tui

The area under the standard normal distribution curve between z=o and z=1.47 is 42.92%.

What is Standard normal distribution?

The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.

The area under the standard normal distribution curve between z=o and z=1.47 can be found as,

Area = (Z=1.47) - (Z=0)

As per the z-table the values of z are,

Z = 1.47 = 0.9292

z = 0 = 0.5

Area = 0.9292 - 0.5

Area = 0.4292 = 42.92%

Thus, The area under the standard normal distribution curve between z=o and z=1.47 is 42.92%.

A parabola has a vertex of (-2,1) and passes through the point (0,-7). What is the value of amplitude

Answers

Answer:

The value of the amplitude is -2

Step-by-step explanation:

The given parameters are;

The vertex of the parabola = (-2, 1)

The point through which the parabola passes = (0, -7)

The equation of the parabola can be expressed as follows;

y - y₀ = a·(x - x₀)²

Where;

y₀ = The y-coordinate of the vertex = 1

x₀ = The x-coordinate of the vertex = -2

Therefore, we substitute the known values of the coordinates of a point  the parabola to get;

-7 - 1 = a·(0 - (-2))²

-8 = 4·a

a = -8/4 = -2

The value of the amplitude a = -2.

An open rectangular box with length of 6 feet, width of 4 feet and height of 2.5 feet is to be painted on all exterior sides, including the bottom, with a special waterproof coating. Each gallon of this special coating covers 12 square feet of surface area and costs $36.00. The box is then to be filled with water that weighs approximately 62 pounds per cubic foot.

A. Find the cost of painting this open box.

B. Find the weight of the water in the filled box

Answer:

A

[tex]x = \$ 294[/tex]

B

[tex]z =  3720 \  pounds[/tex]

Step-by-step explanation:

From the question we are told that  

  The length is  [tex]l  =  6 \ ft[/tex]

    The width is  [tex]b =  4 \ ft[/tex]

   The height is [tex]h  =  2.5 \  ft[/tex]

Generally the total surface area of the open, rectangular box is mathematically represented as

       [tex] T_ A = 2lb + 2lh + 2bh[/tex]

=>   [tex] T_ A = 2(6 * 4) + 2(6 * 2.5) + 2(4 * 2.5)[/tex]  

=>   [tex] T_ A = 98 \ ft^2 [/tex]

From the question we are told that

     $36.00 worth of paint  covers  [tex]12 ft^2[/tex]

So  $x worth of paint covers  [tex]98 \ ft^2[/tex]

=>  [tex]x = \frac{98 * 36}{12}[/tex]

=>   [tex]x = \$ 294[/tex]

Generally the volume of the open, rectangular box is mathematically represented as

     [tex]V  =  l *  b  *  h[/tex]

=>   [tex]V  =  6 *  4  *  2.5[/tex]

=>   [tex]V  =  60 \ ft^3 [/tex]

From the question we are told that  

[tex]1 ft^3[/tex]  weigh 62 pounds

[tex] 60 \ ft^3[/tex] weigh z pounds

=>  [tex]z = \frac{60 * 62}{1}[/tex]

=> [tex]z =  3720 \  pounds[/tex]

She left home at 10:00 am and rode her stallion at a nice, steady 10 miles per hour away from her house

The rate = 10 miles/hour

Father's scooter rate = 15 miles/hour

Based on the data given the number of minutes the father must ride his scooter before catching up to his daughter should measure on a scale of hundreds.
