Answer:

2.3\:\mathrm{in^3},\\1.3\:\mathrm{fl\:oz}

Step-by-step explanation:

The volume of a cone with radius r and height h is equal to V=\frac{1}{3}\cdot r^2\pi\cdot h.

What we're given:

  • Since radius is half the diameter, r is 1.1
  • Height of 1.8

Substituting given values, we get:

V=\frac{1}{3}\cdot 1.1^2\pi \cdot 1.8=0.726\pi\approx \boxed{2.3\:\mathrm{in^3}}

Convert to fluid ounces using the conversion given in the question:

0.726\pi}\cdot \frac{0.554}{1}\approx \boxed{{1.3\:\mathrm{fl\:oz.}}}

Jared‘s grandmother gave him $19 for his birthday he brought eight dollars worth of candy and spent another four dollars on a ne
cestrela7 [59]

Answer:

$7

Step-by-step explanation:

To solve this one we will subtract how much he spends from what he has.  At the start he had 19 and then spent 8 meaning he now has 8 less than when we started so 19-8 is 11.  He now as 11 dollars, then he spend another 4 meaning we have to subtract another 4 dollars.  11-4 is 7.  So he as 7 dollars left at the end.

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Solve for x. round to the nearest hundredth if necessary.
iris [78.8K]

Answer: x=11.47

Step-by-step explanation:

Given the angle of 55 degrees, you know that the adjacent side is "x" and the length of the hypotenuse is 20.

Therefore, you need to remember the following identity:

cos\alpha=\frac{adjacent}{hypotenuse}

Then, knowing that:

\alpha=55\°\\adjacent=x\\hypotenuse=20

 You need to substitute these values intocos\alpha=\frac{adjacent}{hypotenuse}:

 cos(55\°)=\frac{x}{20}

Now, you can solve for "x":

20*cos(55\°)=x\\x=11.471

Rounded to the nearest hundreth:

x=11.47

Alex Ar [27]

Answer:

x = ± \sqrt{20}

Step-by-step explanation:

Given

x² = 20 ( take the square root of both sides )

x = ± \sqrt{20}

which can be simplified to

x = ± 2\sqrt{5}

[ ± means plus or minus ]
