Answer:

256 ft²

Step-by-step explanation:

4 lateral faces + 2 bases

The total area

=2 \times (12 \times 4) + 2 \times (12 \times 5) + 2 \times (5 \times 4)

= 96 + 120 + 40

= 256

Answer ASAP 84.9 66.2 38.2 33.8
tankabanditka [31]

Step-by-step explanation:

You need to use trigonometric stuff here. Since you're given the hypotenuse and an angle you can plug that right into an equation.

Recall that sin is opposite over hypotenuse and cos is adjacent over hypotenuse.

sin(\theta)=\frac{o}{h} \\sin(30)=\frac{x}{14} \\0.5=\frac{x}{14} \\x=7

Now that you know the opposite side (DC) you can use tan, too, but I'm going to use cos.

cos(\theta)=\frac{a}{14} \\cos(30)=\frac{x}{14} \\\frac{\sqrt{3} }{2} =\frac{x}{14} \\x=7\sqrt{3}

This is the adjacent side (BC). I put it in its exact value, but in decimal form it's ≈12.124.

Now you can do the perimeter:

2l+2w\\2(12.124)+2(7)\\24.248+14\\38.25

Your answer is the 38.2

ZanzabumX [31]

Answer:

This study  casts doubts as the hypothesis does not support the women who are smokers, drinkers or use dyes besides the difference of breasts implants.

Step-by-step explanation:

This study  casts doubts as the hypothesis does not support the women who are smokers, drinkers or use dyes.

If the null and alternate hypothesis are formulated as

H0 : silicone breasts implants cause illness in smokers, drinkers and hair dyed people

against the claim

Ha: silicone breasts implants do not cause illness in smokers, drinkers and hair dyed people

then there would be no doubt .

But as the null and alternate hypothesis are

H0: silicone breast implants cause illness in women

against the claim

Ha: silicone breast implants do not cause illness in women

This suggests that both categories of women have same characteristics.

But actually both categories do not have same characteristics. The breast implant women also , smoke, drin and dye hair.

So when the characteristics are changed the illness maybe caused by some other characteristics.
