Answer:

11 c; 12 c; 13 b

Step-by-step explanation:

Question 11

\text{Volume} = \text{4 doses} \times \dfrac{\text{2 T}}{\text{1 dose}}\times \dfrac{\text{15 mL}}{\text{1 T}} = \textbf{120 mL}

Question 12

(a) Add up the total fluid ounces

\begin{array}{rr}\textbf{Liquid} & \textbf{V/oz} \\\text{Juice} & 6 \\\text{Water} & 4 \\\text{Soda} & 8 \\\text{Coffee} & 10 \\\text{Milk} & 6 \\\text{Total fluids} & 34 \\\end{array}

(b) Convert fluid ounces to millilitres

\text{Volume} = \text{34 oz} \times \dfrac{\text{15 mL}}{\text{1 oz }} = \textbf{510 mL}

Question 13

1 L =10 dL

\text{Volume} = \text{80 dL} \times \dfrac{\text{1 L}}{\text{10 dL}} = \textbf{8.0 L}

The cells of a bacteria doubles in every 15 minutes. A scientist begins with a single cell. How many cells will be there after (
Anastaziya [24]

Step-by-step explanation:

Given that:-

  • 1 cell = 15 minutes

So, we can concert 15 minutes to hours.

So,

60 minutes = 1 hour

1 minute = 1/60

15 minutes =

\frac{15}{60}  = 0.25 \: hrs

Okay, now we will apply first for 0.4 hours.

0.25  \: hrs= 1 \: cell

1 \: hr =  \frac{1}{0.25}

0.4 \: hrs =  \frac{0.4}{0.25}

= 1.6 \: cells

= 16  \times  {10}^{ - 1} \: cells

Now, second one:-

10 \: hrs =  \frac{10}{0.25}

= 40 \: cells

= 0.4 \times  {10}^{2}  \: cells

Hope it helps :D

Sin x= 1.5<br> value of x
alina1380 [7]

Answer:

x = π - sin^(-1)(3/2) + 2 π n_1 for n_1 element Z

or x = 2 π n_2 + sin^(-1)(3/2) for n_2 element Z

Step-by-step explanation:

Solve for x:

sin(x) = 1.5

1.5 = 3/2:

sin(x) = 3/2

Take the inverse sine of both sides:

Answer:  x = π - sin^(-1)(3/2) + 2 π n_1 for n_1 element Z

or x = 2 π n_2 + sin^(-1)(3/2) for n_2 element Z

PLEASE HELP URGENT!!!!
Dovator [93]

Answer:

£ 21552.13

Step-by-step explanation:

P= £18790

r =4.9% = \frac{4.9}{100}=0.049

t = 3 years

I = Prt

I = 18790 * 0.049 * 3

 =£ 2762.13

After 3 years , the amount in Dan's account = 18790 + 2762.13

                                                                         = £ 21552.13
