400 g potatoes
450 ml milk

Answers

Answer 1
Answer:

Answer:

60 ml oil, 90 g onions, 1200 g potatoes, 1350 ml milk

Step-by-step explanation:

What you need to do here is multiply all of these ingredients by 3, because the recipe serves 3 and he needs to serve 9, and 9/3 = 3. Therefore, he would have to triple the recipe.

Solve using order of operations.
16 + (4 ∙ 2) – 3

Answers

Answer: 21

Order of operations, multiply first

16 + (4 x 2) - 3

= 16 + (8) - 3

Then add/subtract as needed from left to right

24 - 3

= 21

Answer:

The answer would be 21.

Step-by-step explanation: First, you would multiply what is in the parentheses, 4 x 2 = 8.

Next, you add. 16 + 8 = 24

Then, you subtract. 24 - 3 = 21.

Consider the 1-to10^19 scale on which the disk of the Milky Way Galaxy fits on a football field. On this scale, how far is it from the sun to the alpa centauri (real distance:4.4 light-years) How big is the sun itself on this scale? Compare the sun's size on this scale to the actual size of a typical atom (about 10^-10 m in diameter).

Answers

Answer:

Sun is 0.4162708 cm away from alpha century.

Sun is 1.391016*10^(-10)m.

Sun is 1.391016 time the size of an atom at this scale.

Step-by-step explanation:

Light year is a measure of distance. It is the distance light travels in an year.

Light year = 9.4607*10^(12) km

So 4.4 light years = 4.4*9.4607*10^(12) km

                                41.62708*10^(12) km

Lets scale this down to the level of 1*10^(-19)

41.62708*10^(12)*1*10^(-19) km

=41.62708*10^(-7) km

Change the units to centimeters:

41.62708*10^(-7)*1*10^(5) cm

=41.62708*10^(-2) cm

=0.4162708 cm

Therefore on the new scale sun is 0.4162708 cm away from alpha century.

Diameter of the sun is 1.391016 million km

Lets change Sun's diameter to the new scale:

1.391016*10^(6) *10^(-19)km

=1.391016*10^(-13)km

Lets change kilometers in to meters:

1.391016*10^(-13)*10^(3)m

=1.391016*10^(-10)m

Therefore, sun is 1.391016*10^(-10)m

and an atom is 1*10^(-10)

Therefore the sun is 1.391016 time the size of an atom at this scale.



Final answer:

On a 1-to-10^19 scale, the distance from the Sun to the Alpha Centauri is about 44 cm. On this same scale, the Sun itself would have a diameter of about 150 picometers, which is larger than a typical atom.

Explanation:

The 1-to-10^19 scale means for every actual meter in space, we represent 10^19 meters on our model. The Alpha Centauri is 4.4 light-years away from the sun. Considering 1 light-year equals to approximately 9.46x10^15 meters, the real distance from the sun to Alpha Centauri is about 4.16x10^16 meters. So, on the scale, this is about 0.44 meters or 44 cm.

The Sun's real size, with a diameter of 1.5 million kilometers or 1.5x10^9 meters, is represented as 1.5x10^-10 meters or 150 picometers on the scale. This is much bigger than an actual atom, which has a diameter of 0.1 to 0.5 nanometers or 100 to 500 picometers. Hence, on this scale, the Sun would be larger than a typical atom.

Cassie is a half pound of sugar in her cabinet her cake recipe calls for two tenths of a pound of sugar how many cakes can she make

Answers

The information's given in the question should be very minutely checked. Based on those given information's the answer to the question can easily be deduced.
Amount of sugar in the cabinet of Cassie = 1/2 pound
Amount of sugar required by Cassie to make her cake recipe = 2/10 pound
                                                                                                   = 1/5 pounds
Then
The number of cakes that Cassie can make = (1/2)/(1/5)
                                                                        = 5/2
                                                                        = 2 1/2
So from the above deduction we can easily conclude that Cassie can make a total of 2 cakes with the sugar she has and there will still be some sugar left.

Answer:2cakes
