What is the surface area of this triangular prism rounded to the nearest tenth? A) 48.6km2 B) 63.4 km2 C) 72.6 km2 D) 84.4 km2

Mekhanik [1.2K]

Correct option B) $63.4km^2$ .

<u>Step-by-step explanation:</u>

We have the following figure attached as shown below.

Now, this triangular prism have 2 similar right angled surfaces and 3 rectangular surfaces , Let's calculate area for all of them:

2 similar right angled surfaces

We know that area of triangle = $\frac{1}{2} b(h)$

⇒ $area = \frac{1}{2} b(h)$

⇒ $area = \frac{1}{2} (3.6)(7.7)$

⇒ $area = 13.86km^{2}$

But there 2 such surfaces so , $area = 2(13.86) = 27.72km^2$

3 rectangular surfaces

Area of rectangle = $length(breadth)$

⇒ $area_1 = 3.6(1.8)$

⇒ $area_1 = 6.48km^2$

⇒ $area_2= 7.7(1.8)$

⇒ $area_2 = 13.86km^2$

⇒ $area_3 = 8.5(1.8)$

⇒ $area_2 = 15.3km^2$

Total area = $6.48 + 13.86 + 15.3 = 35.64km^2$

Adding area of 2 similar right angled surfaces & 3 rectangular surfaces:

$Area = 27.72+35.64 = 63.36km^2$ = $63.4km^2$

Correct option B) $63.4km^2$ .

At Mike’s favorite coffee shop, the coffee of the day is either a dark roast, a medium roast, or a light roast. From past experi

DaniilM [7]

Answer:

The correct option is d. 0.60

Step-by-step explanation:

Consider the provided information.

At Mike’s favorite coffee shop, the coffee of the day is either a dark roast, a medium roast, or a light roast.

The coffee being a light roast is 0.15 and the probability of the coffee being a dark roast is 0.25.

Pr(Light roast) = 0.15

Pr(Dark roast) = 0.25

We need to find the probability of the coffee of the day not being a light roast or a dark roast on the next day that Mike visits the coffee shop.

$Pr(\text{Not being light or dark roast}) =1-Pr(\text{light roast})-Pr(\text{dark roast})$

$Pr(\text{Not being light or dark roast}) =1-0.15-0.25$

$Pr(\text{Not being light or dark roast}) =1-0.40$

$Pr(\text{Not being light or dark roast}) =0.60$

Hence, the correct option is d. 0.60
