Answer:

4 lbs left after 5 days

Step-by-step explanation:

First, you need to step up an equation!

You know that Soomin has a total of 20 pounds and that she's using it, so you are going to use subtraction.

She uses 3 1/5 pounds per day so you write:

20 - 3 1/5x

and you know that she wants to know how much she has left after 5 days so you replace the x with 5:

20 - (3 1/5) * 5

Multiply first:

20 - 16

After Subtracting you get the answer:

4 lbs left

Answer:

4 lbs

Step-by-step explanation:

If she gives 3.2 each day you can multiply by 5 to get 16 then subtract 20 - 16 to get 4

It is 90 ft between the bases of baseball diamond. A catcher throws a baseball to the shortstop who is half-way between second a
Hunter-Best [27]

Answer:

127.3 ft

Step-by-step explanation:

A baseball diamond is constructed in a square shape.

The sides are 90 ft each

If a catcher throws a baseball to the shortstop who is half-way between second and third bases, the distance between the third base and the short stop = 1/2(90)

= 45 ft

length of the throw is found using Pythagoras theorem.

Hypothenus ^2 = opposite ^2 + adjacent ^2

= 90^2 + 45^2

Hypothenus = √8100 + 2025

=√10125

= 100.62 ft (approximately)

BRAINLIESTTT ASAP!! :)

"A parabola is curved instead of linear, in your case it is probably just facing up or down so I won't get into square roots for now.So the quadratic equation that you probably have had to memorize (or will soon) is:
x=(-b[+or-]√(b²-4ac))/2a when you have an equation like ax²+bx+c=0Now where does the curve shape come from? You see that little pesky plus or minus in the equation? That's because there are always 2 values (inputs) that will generate the same output. Example:y=x²(2)²=4(-2)²=...4So if you were to follow this pattern, and plot the points on a graph, you would end up with a curve. You end up with a curve because the slope is constantly increasing. 
And this is actually where you start the study of Calculus(!), which is all about measuring slopes (And a bunch of other stuff, but this is the easiest part to explain). Actually, in this case of y=x², the slope at any given point (funnily enough) is equal to 2 times your x-value. 
The point is, your line is curved because unlike a linear equation, the slope is changing (at a constant rate)."

Could someone explain line of best fit IN DETAIL.
iris [78.8K]

Answer:

A line of best fit (or "trend" line) is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.

In right triangle RST below, altitude SV is drawn to
Brilliant_brown [7]

Answer:

ST = 12.2

Step-by-step explanation:

See the attached diagram of the triangle.

Here, Δ RST, Δ RSV and Δ STV all are right triangles.

If we assume that, ST = x and SR = y, then

From Δ RSV and Δ STV we get,

SV² = RS² - RV² = ST² - VT²

⇒ y² - 4.2² = x² - 10.3²

⇒ x² - y² = 88.45 .......... (1)

Now, from Δ RST, we have

ST² + SR² = RT²

⇒ x² + y² = (10.3 + 4.2)² = 210.25 .............. (2)

Now, adding equations (1) and (2) we get,

2x² = 298.7

⇒ x² = 149.35

⇒ x = 12.2 (Rounded to the nearest tenth}

So, ST = 12.2 (Answer)
