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:

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

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

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

$C = 60\ milligrams$

NeTakaya

Answer:

y=-x+8

Step-by-step explanation:

y = mx + b is the basic formula

use the formula y2-y1/x2-x1 to get the slope to get m

-2-5/4-(-3)

-7/7

-1

then use the point slope formula y-y₁=m(x-x₁)

y-5=-1(x-(-3)

y-5=-1x+3

y=-x+8

Find missing length

svetlana [45]

By the Pythagorean theorem
.. 15^2 = 10^2 +a^2
.. 225 = 100 +a^2
.. 125 = a^2
.. √125 = a
.. 5√5 = a ≈ 11.18
The missing side length is 5√5 cm.

The first 5 terms of a sequence are shown below:

nirvana33 [79]

Step-by-step explanation:

To find the formula for the nth term ,

First , find the common difference or common ratio.

Common difference =

$T_2-T_1 \\ - 2 - 3 \\ = - 5$

Common ratio =

$T_2/T_1 \\ \frac{ - 2}{3}$

The common difference applies to the other given numbers for example :

$T_3- T_2 = - 7 - ( - 2) \\ = - 7 + 2 = - 5$

this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is

T_n =a(n-1)d

Where n = no of terms

a= first term

d= common difference

EXPERTS PLEASE HELP!!!!!!!!!!!!!!

Arturiano [62]

Answer:

1. D

2. x=65

Step-by-step explanation:

Hi!

Your answer is D because 78 is 120% of x

120% in decimal point is 1.2.

So it's 1.2x is the same as 120% of x

For question 8:

1.2x=78

Isolate x by divide 1.2 on both sides

78/1.2=65
