Mathematics
1 answer:
Oksana_A [137]3 years ago
3 0

Answer:

2440 km; 1.330 × 10²⁷ kg  

Step-by-step explanation:

(a) <em>Radius of Mercury </em>

D = 4.88 × 10^³ km

D = 2r     Divide each side by 2

r = D/2  

r = (4.88 × 10³)/2

r = 2.44 × 10³ km     Convert to decimal notation

r = 2440 km

(c) <em>Mass difference </em>

Difference = 1.898 × 10²⁷ - 5.68   × 10²⁶     Rationalize exponents

Difference = 1.898 × 10²⁷ - 0.568 × 10²⁷

Difference = 1.330 × 10²⁷ kg

TRUE OR FALSE:
Oksanka [162]

Answer:

It doesn't matter in what order we add our ingredients but if we have a combination to our padlock that is 4-5-6 then the order is extremely important. If the order doesn't matter then we have a combination, if the order do matter then we have a permutation. One could say that a permutation is an ordered combination.

Identify the slope and y-intercept of each of the following lines. Then graph each line.
viktelen [127]

First <u>rewrite the equation</u> in slope intercept form

slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]

\rightarrow \sf 8y = -2x+32

\rightarrow \sf y =\dfrac{ -2x+32}{ 8}

\rightarrow \sf y =\dfrac{ -2x}{ 8} + \dfrac{32}{8}

\rightarrow \sf y =\dfrac{ -1}{ 4}x + 4

<u>comparing</u> with y = mx + b

  • slope: -1/4     and   y-intercept: 4

x-intercept:          ( then y will be 0 )

\hookrightarrow  \sf -2x + 32 = 0

\hookrightarrow  \sf -2x  = -32

\hookrightarrow  \sf x  = 16

In order to graph the line

  • plot x = 16 on the x-axis     coordinate: (16, 0)
  • plot y = 4 on the y-axis     coordinate: (0, 4)
  • Then using a scale/ruler draw a straight line through this points.

Enter an equation for the word sentence. Use the variable n.
Usimov [2.4K]

Answer:

n + 4.4 = 8.1

Step-by-step explanation:

We know we have to write an algebraic equation for the sentence - so "translate" the phrases of the sentence step-by-step. Let the unknown number be represented by the variable n, as the question states.

Start with the phrase "the sum of a number and 4.4." A sum comes as a result of adding numbers together - therefore the first part of the equation must be n + 4.4.

Next, the sentence says "is 8.1." The "is" indicates that the expression we just wrote equals something, so that number must be 8.1. Therefore, the whole equation must be n + 4.4 = 8.1.
