A Web music store offers two versions of a popular song. The size of the standard version is 2.9 megabytes (MB). The size of the
GrogVix [38]

s +h = 1070 ( total number of downloads)

Rewrite as s =1070 - h

2.9s + 4.4h = 4393 ( total download size)

Substitute:

2.9(1070-h) + 4.4h = 4393

Simplify:

3103 - 2.9h + 4.4h = 4393

Combine like terms:

3103 + 1.5h = 4393

Subtract 3103 from each side:

1.5h = 1290

Divide both sides by 1.5:

h = 1290 / 1.5

h = 860

Replace h with 860 in first equation to solve for s:

s + 860 = 1070

s = 1070 - 860

s = 210

There were 210 standard downloads and 860 high quality downloads

Adam has been asked to post a parcel for a family member. He has been told that the parcel weighs 12 lbs 8 oz. 1lb = 16 oz 1lb =
jasenka [17]

Answer:

<em>The weight of the parcel is approximately 6 kilograms.</em>

Step-by-step explanation:

The weight of the parcel is  12 lbs and 8 oz.

1 lb = 16 oz

So,  8 oz = \frac{1}{2}lb = 0.5 lb.

<u>That means,  12 lbs and 8 oz</u> = (12 + 0.5) lbs = 12.5 lbs

Now, 1 lb = 454 g

So,  12.5 lbs = (12.5 × 454) g = 5675 g

As,  1 kilogram = 1000 g

That means, 1 g = 0.001 kilogram

So,  5675 g = (5675 \times0.001) kilograms= 5.675 \approx 6 kilograms. <em>(Rounded to the nearest whole kilogram)</em>

Thus, the weight of the parcel is approximately 6 kilograms.

Can someone please help me this this??
Brrunno [24]

Answers:

bio = 258

sociology = 169

============================================================

Work Shown:

x = number of bio textbooks

y = number of sociology textbooks

x+y = 427 books sold total

y = x-89 since 89 less sociology textbooks were sold compared to bio

Apply substitution to get the following

x+y = 427

x+x-89 = 427 ... replace y with x-89

2x-89 = 427

2x = 427+89

2x = 516

x = 516/2

x = 258 bio textbooks were sold

y = x-89

y = 258-89

y = 169 sociology textbooks were sold

Let P(x) = 3x³-ax+b. If P(1) = P(-1) and P(2)=16, find the values of a and b
kozerog [31]

P(1) = P(-1)

P(1) = 3 - a + b
P(-1) = -3 + a + b

-> 3 - a + b = -3 + a + b
-> 3 - a + b + 3 - a - b = 0
-> 6 - 2a = 0
-> a = 3.

P(2) = 24 - 2a + b -> 24 - (2a - b) = 16 -> 2a - b = 8
-> 6 - b = 8
b = -2.

So, a = 3 and b = -2

Recheck : P(1) = 3 - 3 + (-2) = -2
P(-1) = -3 + 3 + (-2) = -2 => P(1) = P(-1) (true)

P(2) = 24 - 6 + (-2) = 16.

Maggie only wore sandals tracker on two of the days that she trained so from her fitness trackers she verified that on the third
KIM [24]
We know form our problem that the third day she biked 20 miles, so we have the point (3,20). We also know that <span>on the eighth day she biked 35 miles, so our second point is (8,35).

To relate our two point we are going to use the slope formula: </span>m= \frac{x_{2}-x_{1}}{y_{2}-y_{1}}
We can infer form our points that x_{1}=3, y_{1}=20,x_{2}=8, and y_{2}=35. so lets replace those values in our slope formula:
m= \frac{35-20}{8-3}
m= \frac{15}{5}
m=3

Now that we have the slope, we can use the point-slope formula <span>determine the equation of the line that best fit the set for Maggie’s data.
Point-slope formula: </span>y-y_{1}=m(x-x_{1})
y-20=3(x-3)
y-20=3x-9
y=3x+11

We can conclude that the equation of the line that  best fit the set for Maggie’s data is y=3x+11.
