Answer:

Six

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

$V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}$

(c) Banana flavouring

$V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL }$

2. Calculate the total volume

Chlorpheniramine = 100 mL

Lidocaine = 59

Banana flavouring = <u> 2.5 </u>

TOTAL = 162 mL

3. Calculate the number of doses

$\text{Doses} = \text{162 mL} \times \dfrac{\text{1 dose}}{\text{10 mL}} = \text{16.2 doses}\\\\\text{You can't take a fraction of a dose, so the there are $\large \boxed{\textbf{16 doses}}$}$

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?

vlada-n [284]

Y=9.25 because inorder to solve this we need to first take 5*.3 which equals 1.5 now that we have this we can move on we now have the equation 1.5 + 2y = 20 so now we need to continue working on getting y by it self so we subtract 1.5 from each side and then that leaves us with 2y=18.5 now we divide by 2 which leaves us with y=9.25

Solve: 3(1-2x) > 3-6x

sweet [91]

3(1 - 2x) > 3 - 6x use distributive property

(3)(1) + (3)(-2x) > 3 - 6x

3 - 6x > 3 - 6x add 6x to both sides

3 > 3 FALSE

Jake tosses a coin up in the air and lets it fall to the ground. The equation that models the height (in feet) and time (in seco

adoni [48]

Answer:

The maximum height of coin Jake tosses is 15 feet.

Step-by-step explanation:

Given Jake tosses a coin up in the air

and the height of coin is model by h(t)= $(-16)t^{2} +24t+6$

To find height of the coin when Jake tosses it:

When a coin is in the hand of Jake, time t=0

Height of coin is h(t)= $(-16)t^{2} +24t+6$

h(0)= $(-16)(0)^{2} +24(0)+6$

h(0)=6 feet.

Therefore, Height of coin at time t=0 is 6.

For maximum height of the coin,

h(t)= $(-16)t^{2} +24t+6$

Differentiating both side,

$\frac{d}{dt}h(t)=\frac{d}{dt}[(-16)t^{2} +24t+6]$

$\frac{d}{dt}h(t)=\frac{d}{dt}[(-32)t+24]$

$\frac{d}{dt}h(t)=0$

$\frac{d}{dt}[(-32)t+24]=0$

t= $\frac{24}{32}$

t= $\frac{3}{4}$

t=0.75

Now,

h(t)= $(-16)t^{2} +24t+6$

h(0.75)= $(-16)(0.75)^{2} +24(0.75)+6$

h(0.75)=15 feet.

The maximum height of coin jake tosses is 15 feet.
