Here, we need to find the monthly and the weekly growth rate

The monthly growth rate is 99.33 ounces and the weekly growth rate is 22.9 ounces

Weight at birth = 8 ounces

Weight at one year =75 ounces

1 pound = 16 ounces

75 pounds = 1200 ounces

Additional weight after birth = Weight at one year - Weight at birth

= 1200 ounces - 8 ounces

= 1,192 ounces

There are 12 months in a year

Growth rate per month = Additional weight after birth / 12

= 1,192 / 12

= 99.33 ounces per month

There are 52 weeks in a year

Growth rate per week = Additional weight after birth / 52

= 1,192 / 52

= 22.9 ounces per week

Graphs are used to show the relationship between two variables. In the given graph, as the value of x increases, the value of y decreases.

Given that:

[tex]y = \frac{10}{x}[/tex]

The above function is an inverse function.

This means that:

As the value of x increases, the value of y decreases

Take for instance:

[tex]x= 1[/tex]

[tex]y = \frac{10}{1} = 10[/tex]

Now, [tex]x = 2[/tex]

[tex]y = \frac{10}{2} = 5[/tex]

Notice that:

As x increases from 1 to 2, the corresponding values of y decreases from 10 to 5

Hence, (b) is correct

Step-by-step explanation:

Reduce fractions to their lowest terms equivalents

Multiply the numerators and denominators of the fractions separately

[tex]\frac{7}{15}[/tex] * 120 = convert to fraction

[tex]\frac{7}{15}[/tex] * [tex]\frac{120}{1}[/tex] = convert to fraction

[tex]\frac{7 * 120}{15}[/tex] = apply fraction rule  [tex]\frac{a}{b}[/tex] * [tex]\frac{c}{d}[/tex] = [tex]\frac{a * c}{b * d}[/tex]

[tex]\frac{7 * 120}{15 *1}[/tex] = apply rule a * 1 = a  15 * 1 = 15

[tex]\frac{120}{15}[/tex] = 8 divide the numbers

7 * 8 = 56 multiply the numbers

Answer:

Step-by-step explanation:

Original equation

    √x+6-4 = x

   Isolate

    √x+6 = 4+x

Raise both sides to the second power

    (√x+6)2 = (4+x)2

    After squaring

    x+6 = x2+8x+16

Rearranged equation

    x2  + 7x  + 10 = 0

    This equation has two rational roots:

      {x1, x2}={-2, -5}

Original equation, root isolated

    √x+6 = 4+x

    Plug in  -2 for  x  

     √(-2)+6 = 4+(-2)

     Simplify

     √4 = 2

     Solution checks !!

    Solution is:

     x =  -2

Original equation, root isolated

    √x+6 = 4+x

    Plug in  -5 for  x  

     √(-5)+6 = 4+(-5)

     Simplify

     √1 = -1

     Solution does not check

     1 ≠ -1

 A store advertises,

"Buy one and get one half off"

Which means if we buy one, half the price of one will be discounted.

In other words "50% discount on each item we buy"

We will $440 for 10 skates.

Original cost of skates = $88

After 50% discount price of one skate = $88 - $44 = $44

Cost of 10 pairs of skates = 44 × 10

                                           = $440

     Therefore, we will pay $440 for 10 skates.

Answer:

if i am rightthe two other angles arre 39

Step-by-step explanation:

if a triganle is 180 degrees and you have already one angle then all you do is subtract 180 and 102

180-102= 78

then since you need the other two angles all you do is divide it by 2

so 78/2= 39 so the two missing anlges are 39

[tex]ad = ab + bc + cd[/tex]

--------------------------------

[tex]ab = 5bc[/tex]

In terms of x, [tex]bc = x, ab = 5x[/tex]

--------------------------------

[tex]bc = 2cd[/tex]

In terms of x, [tex]cd = \frac{x}{2}[/tex]

--------------------------------

[tex]\frac{x}{2} = 10[/tex]

[tex]x = 20[/tex]

--------------------------------

[tex]bc = x = 20[/tex]

[tex]ab = 5x = 5(20) = 100[/tex]

--------------------------------

[tex]ad = ab + bc + cd = 100 + 20 + 10 = 130[/tex]

The distance between the two cities is of 130 miles.

All the elements of the given set {2,4,8,...,256} are - {2, 4, 8, 16, 32,64, 128, 256} that are total 8 in numbers.

The set is formed by the number of objects in a particular manner, these objects are called elements of the set. The elements of the set are written inside a curly bracket separated by a comma in a particular or specific order.

There are two methods to represent the set and its elements that are:

in this case, {[tex]2^{1},2^{2},2^{3},2^{4},2^{5},2^{6},2^{7},2^8[/tex]} as we know,

so the set notation would be :
