Answer:

a = 117/40

Step-by-step explanation:

a/6.5 = 45/100

convert the decimal into a fraction

a/ 13/2 = 45/100

reduce the fraction with a 5

a/ 13/2 = 9/20

simplify the complex fraction

2a/13 = 9/20

simplify the equation using cross-multiplication

40x = 117

divide both sides by 40

a = 117/40

answer: a = 117/40

8. A box is filled with candies in different colors. We have 40 white candies, 24 green ones, 12
Darya [45]

Answer:

P(Green\ or\ Red) = 0.30

Step-by-step explanation:

Given

White = 40

Green = 24

Red = 12

Yellow = 24

Blue = 20

Required

P(Green\ or\ Red)

The total numbe of candy is:

Total = 40 + 24 + 12 + 24 + 20

Total = 120

This probability is calculated as:

P(Green\ or\ Red) = P(Green) + P(Red)

For each, we have:

P(Green\ or\ Red) = \frac{Green}{Total} + \frac{Red}{Total}

Take LCM

P(Green\ or\ Red) = \frac{Green+Red}{Total}

P(Green\ or\ Red) = \frac{24+12}{120}

P(Green\ or\ Red) = \frac{36}{120}

P(Green\ or\ Red) = 0.30

Find the product of z1 and z2, where z1 = 7(cos 40° + i sin 40°) and z2 = 6(cos 145° + i sin 145°).
Oduvanchick [21]
For two complex numbers z_1=re^{i\theta}=r(\cos\theta+i\sin\theta) and z_2=se^{i\varphi}=s(\cos\varphi+i\sin\varphi), the product is

z_1z_2=rse^{i(\theta+\varphi)}=rs(\cos(\theta+\varphi)+i\sin(\theta+\varphi))

That is, you multiply the moduli and add the arguments. You have z_1=7e^{i40^\circ} and z_2=6e^{i145^\circ}, so the product is

z_1z_2=7\times6(\cos(40^\circ+145^\circ)+i\sin(40^\circ+145^\circ)=42(\cos185^\circ+i\sin185^\circ)=42e^{i185^\circ}

D. All irrational numbers are rational numbers.

I attached the diagram my teacher showed us when we learned about this. I think it makes it a lot less confusing.

Hope this helps :)
