Answer:
30 min
Step-by-step explanation:
1 butcher can prepare 1 cows in 2 hours
2 can prepare twice as fast 2/2=1 hour
4 can prepare 4 times as fast 2 hours/4=30 min
Check work
30 min*4=120 min=2 hours
So basically you want to find the total percentage of cakes that weren't sponge cakes first.
You already have the 50% of party cakes. For the 1/5 percent of fruit cakes, you can multiply it by 20/20, to get 20/100, and then just take the 20 to get 20% that were fruit cakes.
Now you can just add the percentages together.
50% + 20% = 70%
So now you know 70% weren't sponge cakes, out of 100%.
So here you can just subtract 70% from 100% to figure out the remaining part of 100%, which must be sponge cakes.
100% - 70% = 30%
So 30% of the cakes were sponge cakes.
Answer:
CD
Step-by-step explanation:
- Reflection is a rigid transformation which always create a congruent image of the original image or pre-image.
If quadrilateral ABCD is the result of a reflection of quadrilateral LMNO over the line.
Then both the quadrilaterals are congruent.
To find the line segment in the image corresponds to NO in the pre-image, just check the order of the letters in the name of quadrilaterals.
Also, In reflection image and its pre-image are equidistant from the line of reflection
hence, CD is the line segment in the image corresponds to NO in the pre-image.
