4 batteries in a packet.

Sarah bought P packets of battery.

So, she bought 4P batteries

Then,

10 batteries in a box

Sarah bought B boxes of battery

So, she bought 10B batteries

That is,

Sarah bought a total of 4P + 10B batteries which is 7 batteries

Answer:

$\boxed{\text{\sf \Large 138.6 mm^2 $}}$

Step-by-step explanation:

Area of rectangle

$15 \times 5=75$

Area of circle (semi-circle+semi-circle)

$r=(15-3-3) \div 2 = 4.5$

$\pi \times 4.5^2=20.25\pi$

Add both areas

$20.25\pi +75$

$20.25 \times 3.14 +75=138.585$

Answer:

a) 1 unit per hour will be infused.

b) 5mL per hour will be infused.

Step-by-step explanation:

Each question can be solved as a rule of three with direct measures, that means we have a cross multiplication.

a. How many units per hour will be infused?

20 units are going to be infused in 20 hours. How many units are going to be infused each hour?

1 hour - x units

20 hours - 20 units

$20x = 20$

$x = \frac{20}{20}$

$x = 1$

1 unit per hour will be infused.

b. How many milliliters per hour will be infused?

100mL are going to be infused in 20 hours. How many mL are going to be infused each hour?

1 hour - x mL

20 hours - 100 mL

$20x = 100$

$x = \frac{100}{20}$

$x = 5$

5mL per hour will be infused.
