Juli uses 12 ounces of cheese in her potato soup recipe. Her recipe yields 8 servings. If Juli needs enough for 20 servings, how

balandron [24]

Answer:

30 ounces

Step-by-step explanation:

First you have to make the proportion ounces to servings.

Then you put 12 for ounces and 8 for servings.

After you put an equal sign and after the equal sign you put for ounces an x and for servings 1.

Then you put 8x=12.

after you divide 8x by 8 to get x and 12 by 8 to get 1.5.

Lastly you do 1.5 times 20 to get 30.

A scale of a room is 3.5 in. long and 2 in. wide. Scale is 1:20. What is the area of the actual room in square feet?

AleksAgata [21]

First, multiply 3.5 by 20 and 2 by 20 to get the real width and length of the room(That would be 70 in. long and 40 in. wide). Then, change that into feet (Which would be 5.8 ft. long and 3.3 ft. wide). Lastly multiply the length by the width. The answer would then be 19.14.

The center of a circle is located at (5, −5) . The radius of the circle is 3.

Keith_Richards [23]

The equation of a circle is:

$(x - xc) {}^{2} + (y - yc) {}^{2} = r {}^{2}$

Where (xc,yc) are the coordinates of the center.
Center (5, -5)
Radius = 3
(x-5)²+(y+5)²=3²
x²-10x+25+y²+10y+25=9
x²+y²-10x+10y+41=0

Find the area of the figure.

givi [52]

these are just two semi-circles, one with a diameter of 22 and the other with a diameter of 30 - 22, or 8, and therefore their radius are 11 and 4 respectively.

$\bf \textit{area of a semi-circle}\\\\ A=\cfrac{\pi r^2}{2}~~,~~ \stackrel{r=11}{A=\cfrac{\pi 11^2}{2}}\implies A=\cfrac{121\pi }{2}~~,~~ \stackrel{r=4}{A=\cfrac{\pi 4^2}{2}}\implies A=8\pi \\\\ -------------------------------\\\\ \stackrel{\textit{total area of the figure}}{\cfrac{121\pi }{2}+8\pi }\implies \cfrac{121\pi +16\pi }{2}\implies \cfrac{137\pi }{2}$
