You need to do the inverse calculation. So basically, you just need to take the number after the =, which is -8.6, and the number before (-6.8) and take them away. So you would do
- 8.6
- - 6.8
-----------
???

Hope this helps and you can now work out!!

A) work out the radius of the mercury, giving your answer as an ordinary number

guapka [62]

Answer:

a. 2,440 km

b. $1.33*10^{27} kg$

Step-by-step explanation:

a. Diameter of Mercury = $4.88*10^3$

Radius of Mercury = ½ of its diameter = $\frac{4.88*10^3}{2}$

Radius of Mercury = $2.44*10^3$

To convert the radius to ordinary number, multiply 2.44 by 1,000.

Radius of Mercury as an ordinary number = $2.44*1,000 = 2,440 km$

b. Mass of Jupiter = $1.898*10^{27} kg$

Mass of Saturn = $5.68*10^{26} kg$

Difference between mass of Jupiter and mass of Saturn = $1.898*10^{27} - 5.68*10^{26}$ (subtract 5.68 from 1.898 = 5.68. we would retain the largest exponent, which is raised to the lower of 27.)

$= 1.33*10^{27}$

A tennis player wins a match 55% of the time when she serves first and 47% of the time when her opponent serves first. The playe

Ray Of Light [21]

ok so she has a 50% chance of serving first so if she serves first she has a 55% percent chance of winning multiply .55 and .50 to get .275 now she also has a 50% chance of not serving first so multiply .47 and .50 to get .235 now that you have the two probabilities of her winning you add them together so .275+.235 = .51 so she has a <u>51%</u> chance of winning the game

Help me please I need to do this

Consider the attached tree.

You start from the root, and with each level you create a sub-branch for each of the choices you have.

So, the root has two children, white and multigrain bread.

Each of those children has three children, because you have three meat choices

Each of those children has two children, because you have two cheese choices.

Then, you identify all the sandwiches by choosing a leaf, and read the label that lead you there.

For example, leaf number 4 represents a sandwich with white bread, turkey and provolone.
