castortr0y [4]
If you would like to know the purchase price of Wilma's game, you can calculate this using the following steps:

15% of $43.89 = 15% * 43.89 = 15/100 * 43.89 = $6.5835 = $6.58

$43.89 - $6.58 = $37.31

5% of $37.31 = 5% * 37.31 = 5/100 * 37.31 = $1.8655 = $1.87

$37.31 - $1.87 = $35.44

The correct result would be <span>$35.44.</span>

Help solve for x. round to the nearest tenth​
mars1129 [50]

Answer:

60.1

Step-by-step explanation:

Use cosine for this one- you get cos37 = adjacent/hypotenuse, or cos37 = 48/x

Solve for x and x = 48/cos37, or 60.1

Hopefully this helps! Let me know if you have any questions

Solve the equation. 10.35+2.3h=-9.2
Readme [11.4K]

Answer:

h = -8.5

Step-by-step explanation:

10.35+2.3h=-9.2

Subtract 10.35 from each side

10.35-10.35+2.3h=-9.2-10.35

2.3 h =-19.55

Divide each side by 2.3

2.3h/ 2.3 = -19.55/2.3

h =-8.5

Answer:

A.

SA= \frac{2}{3} \pi rl+16 \pi r^2

Step-by-step explanation:

Surface area of the original cone

SA= \pi r l + \pi r^2... (1)

When, radius is quadrupled and slant height is reduced to one sixth

i. e. \: \:r = 4r\: \: \&\:\: l= \frac{1}{6}l

Plug the above values of r and l in equation (1), new surface area becomes:

SA= \pi (4r)\times \frac{1}{6} l+ \pi (4r)^2

SA= \frac{4}{6} \pi rl+16 \pi r^2

\huge \purple {\boxed {SA= \frac{2}{3} \pi rl+16 \pi r^2}}
