Answer: 6 cups

Step-by-step explanation:

Make a proportion

3 cups of peanuts to 2 cups of chocolate, and 9 cups of peanuts for x cups of chocolate

3/2=9/x

Cross multiply

3*x=2*9

3x=18

Divide by 3 on both sides

x=6

So, 6 cups of chocolate for 9 cups of peanuts

Hope this helps! :)

Law of cosines <br><br> HELP MES
Lorico [155]

Answer:

70.52 degrees

Step-by-step explanation:

To find the angles, we must first find the lengths of each side of the triangle. Adding up the respective radii, we can see that

XY = 5+4 = 9 CM

XZ = 6+5 = 11 CM

ZY = 4+6 = 10 CM

Now we can apply the cosine rule

C\:=\:\sqrt{A^2+B^2-2ABcosx}

We need to rearrange the rule to solve for x, our missing angle

x\:=\:cos^{-1}\left(\frac{a^2+b^2-c^2}{2ab}\right)

solving for our unknown angle:

x\:=\:cos^{-1}\left(\frac{9^2+10^2-11^2}{2\cdot 9\cdot 10}\right)

x\:=\:70.52^{\circ }

Therefore angle YXZ is 70.52 degrees

s. Blake spent 11 hours making gift baskets for families. Each gift basket took 1/5 hours to make. How many gift baskets did Ms.
Iteru [2.4K]

Answer:

55

Step-by-step explanation:

If 1 gift takes 1/5 an hour, then 5 gifts would take one hour. So if she makes 5 gifts an hour for 11 hours she would make 55 gifts in 11 hours.

9.2 million was calculated as a percentage of 132 million. likewise 13.4 million was determined as a percentage of 142 million.
lora16 [44]
I assume you need the difference between the percentages,

if
132 mil...........................100%
9.2 mil............................x
x=(9.2 mil * 100)/132= 6.96%

142 mil...........................100%
13.4 mil..........................y

y=(13.4 *100)/142= 9.43%

the difference is
9.43-6.96=2.47 %
