Answer: it’s 93cm^

Step-by-step explanation:

remember that the bottom of the triangular prism/top base don’t count as surface area.

first equation for the surface of the triangular prism: 1/2ps = 1/2•12•4 = 24m

add it to the surface area of the rectangular prism: 3•3 + 5•3•4 = 69m

then simply add them

your answer is 93m^!

enjoy :))

Diano4ka-milaya [45]

Answer: (C) 0.1591

Step-by-step explanation:

Given : A manufacturer of radial tires for automobiles has extensive data to support the fact that the lifetime of their tires follows a normal distribution with

$\mu=42,100\text{ miles}$

$\sigma=2,510\text{ miles}$

Let x be the random variable that represents the lifetime of the tires .

z-score : $z=\dfrac{x-\mu}{\sigma}$

For x= 44,500 miles

$z=\dfrac{44500-42100}{2510}\approx0.96$

For x= 48,000 miles

$z=\dfrac{48000-42100}{2510}\approx2.35$

Using the standard normal distribution table , we have

The p-value : $P(44500$

$P(z$

Hence, the probability that a randomly selected tire will have a lifetime of between 44,500 miles and 48,000 miles = 0.1591

nataly862011 [7]

Answer:

$42

Step-by-step explanation:

Given that,

Galore Super Store buys the latest video game at a wholesale price of $30.00.

The markup rate at Game's Galore Super Store is 40%.

We need to find the price from the store. It can be calculated as follows :

$C=30+\dfrac{40}{100}\times 30\\\\=30+12\\\\=\$42$

Hence, we will pay $42.
