Answer:

7,460

Step-by-step explanation:

Whole numbers are counting numbers like 0, 1, 2, 3, . . .. Whole numbers are positive integers including 0

When rounding a number to the nearest whole number, firstly check the first digit after the decimal point. If the first digit is less than 5 we don't round up, but if the first digit is 5 or greater we round up.

Given the number 7,459.82

We check, the first digit after the decimal point, since this digit is greater than 5 (i.e. 8) we round u to get 7,460

What is the prescribed dosage of a certain medicine for a 6-year-old child if the adult dosage of

Serhud [2]

Answer:

The dose in milligrams of a 6-year-old child is 60.

Step-by-step explanation:

The formula is:

$C = \frac{a}{(a+ 12)}A$

We know that

A= adult dosage in milligrams=180 milligrams

a = age of the child = 6 years-old

So the child’s dosage in milligrams is:

$C = \frac{6}{(6+12)}*180$

$C = \frac{1}{(3)}*180$

$C = \frac{180}{(3)}$

$C = 60\ milligrams$

Match each expression it to an equivalent expression

kykrilka [37]

Hi there!

»»————-　★　————-««

I believe your answer is:

$\frac{4^2}{2^2} = 4\\\\(8-4)*4=4^2\\\\2^2 + 2^2 = 8$

»»————-　★　————-««

Here’s why:

$\boxed{\text{Simplifying each expression:}}\\\\\frac{4^2}{2^2}\\---------\\\\\\rightarrow \frac{16}{4}\\\\\rightarrow \boxed{4}\\\\ \boxed{\frac{4^2}{2^2}=4}$

⸻⸻⸻⸻

$(8-4) * 4\\-----------\\\rightarrow (4)*4\\\\\rightarrow \boxed{16}\\\\\text{We can also tell...}\\\\4^2 = 4 * 4 = \boxed{16}\\\\\text{So...}\\\\\boxed{(8-4)*4 = 4^2}$

⸻⸻⸻⸻

$2^2 + 2^2\\--------------\\\rightarrow 4 + 2^2\\\\\rightarrow 4 + 4\\\\\rightarrow \boxed{8}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

30 POINTS! ANSWER ASAP PLEASE!!! WILL THANK ACCOUNT AND ALL ANSWERS!!

Sindrei [870]

Answer:

16.9 units

Step-by-step explanation:

Sometimes the easiest way to work these problems is to get a little help from technology. The GeoGebra program/app can tell you the length of a "polyline", but it takes an extra segment to complete the perimeter. It shows the perimeter to be ...

14.87 + 2 = 16.87 ≈ 16.9 . . . units

_____

The distance formula can be used to find the lengths of individual segments. It tells you ...

d = √((Δx)² +(Δy)²)

where Δx and Δy are the differences between x- and y-coordinates of the segment end points.

If the segments are labeled A, B, C, D, E in order, the distances are ...

AB = √(5²+1²) = √26 ≈ 5.099

BC = √(1²+3²) = √10 ≈ 3.162

CD = Δx = 3

DE = √(3²+2²) = √13 ≈ 3.606

EA = Δy = 2

Then the perimeter is ...

P = AB +BC +CD +DE +EA = 5.099 +3.162 +3 +3.606 +2 = 16.867

P ≈ 16.9
