13,328.73

To find this, first you need to find the radius which can be found through the pythagorean theorem set up as so:

24^2 + b^2 = .51^2

This gets you 44.45cm.

You then plug this in to the surface area equation of a cone which is:

SA = pi x radius (radius + square root of h^2 + r^2 unsquare root)

SA = pi x 44.45cm ( 44.45cm + square root of 25cm^2 + 44.45cm^2 unsquare root)

SA = 13,328.73cm^2

Hope this helps!

Check the picture below.

bearing in mind the "slant height" is 0.51 meters, since there are 100 cm in 1 meter, then in 0.51m there are 0.51*100 or 51 cm.

\bf \textit{surface area of a cone}\\\\
SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~
\begin{cases}
r=45\\
\sqrt{r^2+h^2}=51
\end{cases}
\\\\\\
SA=\pi (45)(51)+\pi (45)^2
\\\\\\
SA=2295\pi +2025\pi\implies SA= 4320\pi

A.) 7^4x = 10
log base 10 (7^4X) = log base 10 (10)
4x log base 10 (7) = 1
4x (0.8451) = 1

There are 175 baskets of fruit in the supermarket. 13 baskets of them are bananas. What percent of the baskets are not bananas?
alexira [117]

Based on the information given the percent of the baskets that are not bananas is: 92.57%.

<h3>Percent of the baskets that are not bananas </h3>

Using this formula

Percentage=(Number of baskets of fruit-Basket of bananas)/Number of baskets of fruit

Let plug in the formula

Percentage=(175-13)/175

Percentage=162/175×100

Percentage=92.57%

Inconclusion the percent of the baskets that are not bananas is: 92.57%.

M is the midpoint of LN. What is the measure of LM= 3x and LN= 2x + 2, find LM.
raketka [301]

Answer:

LM = 1.5

LN = 3

Step-by-step explanation:

From the question given:

M is the midpoint of LN

LM = 3x

LN= 2x + 2

LM =.?

Next, we shall determine the value of x. This is illustrated below:

Since M is the midpoint of LN, it means that when we divide LN by 2 the result will be LM i.e

LN /2 = LM

With the above formula, we can obtain the value of x as follow:

LN= 2x + 2

LM = 3x

x =..?

LN /2 = LM

2x + 2/ 2 = 3x

Cross multiply

2 × 3x = 2x + 2

6x = 2x + 2

Collect like terms

6x - 2x = 2

4x = 2

Divide both side by 4

x = 2/4

x = 0.5

Finally, we can obtain LM and LN as follow:

LM = 3x

x = 0.5

LM = 3 × 0.5

LM = 1.5

LN= 2x + 2

x = 0.5

LN = 2(0.5) + 2

LN = 1 + 2

LN = 3
