If Brenda decides to use milliliters and leaders in terms room instead and each person at the party will drink about 750 mL after 32 people and they each drink about 750 mL how many liters of punch open does mom need to buy?

Answers

Answer:

24 litres

Step-by-step explanation:

Given that :

Number of people present at party = 32

Volume of drink consumed by each person in mL = 750 mL

To consumption in mL:

Number of people * volume consumed by each

32 * 750 mL

24000 mL

24000 mL to L

1000 mL = 1 L

24000 mL = (24000/ 1000)L

= 24 L

work out the circumference of a cirlce with a diameter of 1.8m

Answers

Answer:

5.56 m

Step-by-step explanation:

Circumference = 2πr

r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:

1.8 ÷ 2 = 0.9

Circumference = 2 × π × 0.9

= 5.56 m ( in 3 significant figures )

write an equation of the line that passes through the point (0,3) and whose slope is 2

Answers

Answer:

y - 2x = 3

Step-by-step explanation:

Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:

y - 3 = 2(x - 0), or

y - 3 = 2x, or

y - 2x = 3

Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b:  it is 3.

The letters in the word JANUARY were put in a bag and drawn randomly. What is the probability of picking an a?

Answers

Answer: 2/7

Step-by-step explanation:

There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"

2/7

there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.
