Can someone help me on this?

Mathematics
1 answer:
Setler79 [48]4 years ago
7 0

Answer:

⅜ or ⅗

Step-by-step explanation:

I say ⅜ because of how many variables you can take into account 3 different colors, and a 2 sided coin, lastly 3 different numbers. So in total that is 8 possible variables and the 3 being blue, heads, and landing on 1.

Now I say ⅗ because of this perspective on the variables. You have the 3 colors, and your two sided coin but thing here is that the 1 is basically another color so the question is technically asking for the probability of spinning blue, landing on heads and landing on red in a sense.

Go with your gut though between those 2

The distance from the earth to the moon is 3.84 x 105 km
Anarel [89]

Part (a)

<h3>Answer:  3.84 \times 10^8 \text{ meters}</h3>

---------------------

Explanation:

Multiply by 1000 to go from km to meters.

This is because 1000 m = 1 km.

Multiplying by 1000 in scientific notation means we add 3 to the exponent 5. The 3 is because 1000 = 10^3.

So the 3.84 \times 10^5 \text{ km} becomes 3.84 \times 10^8 \text{ meters}

===========================================================

Part (b)

Answer in standard form:  960,000 seconds

Answer in scientific notation: 9.6\times10^{5} \text{ seconds}

---------------------

Work Shown:

\text{distance} = \text{rate}*\text{time}\\\\\text{time} = \frac{\text{distance}}{\text{time}}\\\\\text{time} = \frac{3.84 \times 10^8 \text{ meters}}{400 \ \text{ m}/\text{s}}\\\\\text{time} = \frac{3.84 \times 10^8}{4 \times 10^2} \text{ seconds}\\\\\text{time} = \frac{3.84}{4}*\frac{10^{8}}{10^2} \text{ seconds}\\\\\text{time} = 0.96 \times 10^{8-2} \text{ seconds}\\\\\text{time} = 0.96\times 10^{6} \text{ seconds}\\\\

\text{time} = (9.6\times10^{-1})\times10^{6} \text{ seconds}\\\\\text{time} = 9.6\times(10^{-1}*10^{6}) \text{ seconds}\\\\\text{time} = 9.6\times10^{-1+6} \text{ seconds}\\\\\text{time} = 9.6\times10^{5} \text{ seconds}\\\\\text{time} = 960,000 \text{ seconds}\\\\

To go from the scientific notation to standard form, move the decimal point 5 spaces to the right. The 5 is from the exponent.

It would be B) 6 cm. If you construct the triangle, and add the angle measure of 80 + 50= 130 , and then 180- 130= 50, you see that the triangle is isosceles.

Use function notation to write the equation of the line
natali 33 [55]

f(x)+mx+b\to y=mx+b

We have two points:

(-4,\ -8);\ (0,\ -4)

The point slope form of the line:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

substitute

m=\dfrac{-4-(-8)}{0-(-4)}=\dfrac{4}{4}=1\\\\y-(-8)=1(x-(-4))\\\\y+8=x+4\ \ \ |-8\\\\y=x-4

Answer:

f(x)=x-4
