Candace ate 3 over 4 cup of cereal. The box of cereal states that one serving of cereal is equal to 2 over 3 cup. Which fraction
choli [55]

Answer: Candace ate \dfrac9{12}  servings.

Step-by-step explanation:

Given: Candace ate \dfrac34 cup of cereal.

The box of cereal states that 1 serving of cereal =  \dfrac23 cup.

i.e. 1 cup = \dfrac32 servings   [Multiply \dfrac32 both sides]

⇒ \dfrac{3}{4} cup = \dfrac34\times\dfrac32 servings

    =     \dfrac9{12}  servings  [which is the number of servings she ate]

Hence, Candace ate \dfrac9{12}  servings.

ValentinkaMS [17]

Answer:

C : $58.36

Step-by-step explanation:

Given:

A store holiday sale has an item marked down by $10.

Discount on new price = 25%

Final price was $36.27.

Question asked:

what was the original ?

Solution:

Let original price = x

New price = x - 10

Original price - marked down amount - discount amount = $36.27

x - 10 -25\% of(x - 10 ) = 36.27\\

x - 10 - \frac{25}{100} (x - 10) = 36.27\\x - 10 - 0.25(x - 10) = 36.27\\x - 10 -0.25x +2.5 = 36.27\\0.75x - 7.5 = 36.27\\

Adding both side by 7.5

0.75x = 43.77\\

Dividing both side by 0.75

x = 58.36

Therefore, the original price was $58.36

jake performed an experiment to find out which type of chocolate melts the fastest, milk chocolate or dark chocolate. He tested
antoniya [11.8K]

Answer:

The correct option is;

After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt

Step-by-step explanation:

Here we have  for the milk chocolate

Min = 29 s

Lower quartile Q₁ = 44 s

Median = 64 s

Upper quartile Q₂ = 93 s

Max = 129 s

For the dark chocolate

Min = 210 s

Lower quartile Q₁ = 237 s

Median = 259 s

Upper quartile Q₂ = 295 s

Max = 320 s

As seen from the values of the box plot, after the median time of 64 seconds which represents half of the test results of the milk chocolate about half of the brands of milk chocolate are likely to melt, while the dark brands only start to melt after 210 seconds.

Therefore the correct option is

After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt.
