Answer:  1\frac{1}{4}\ cups is needed for 5 servings.

Step-by-step explanation:

Since we have given that

Hemal wanted to make desert for her family for which they made the recipe,

For 8 servings , the number of cups of flour is needed = 2

We will use "Unitary Method" ,

For 1 serving, the number of cups of flour is needed is given by

\frac{2}{8}=\frac{1}{4}

For 5 servings, the number of cups of flour is needed is given by

\frac{1}{4}\times 5=\frac{5}{4}=1\frac{1}{4}\ cups

Hence, 1\frac{1}{4}\ cups is needed for 5 servings.

Mickey used these calculations to find how much he would spend on 7 cartons of eggs, if 12 cartons of eggs cost $22.20. Describe
timofeeve [1]
Mickey incorrectly calculated the unit price:
\frac{12}{22.20} = 0.54

The correct operation is:
\frac{22.20}{12} = 1.85

Each carton costs 1.85, so 7 cartons cost
1.85 \times 7 = 12.95

AVprozaik [17]

Answer:

6%

Percentage of teachers = 6%

Step-by-step explanation:

Given;

Number of grade k-2 students = 137

Number of grade 3-5 students = 145

Total = 300

Number of teachers = 300 - (137+145) = 18

Percentage of teachers = (number of teachers÷total)× 100%

%T = (18/300) × 100

%T = 6%

Please help me with this
xenn [34]

Step-by-step explanation:

based on my understanding of the dreidel, this is a regular spinner with 4 equal sides (but different symbols on them, so, we can clearly distinguish between the possible 4 different outcomes).

in other words, this resembles a die with only 4 sides and therefore only 4 equally probable outcomes.

and therefore, the probability to get the specified symbol in 1 attempt is indeed 1/4.

remember, a probability is always desired cases over totally possible cases.

and here, we have one desired outcome out of 4 possible outcomes. hence the probability of 1/4.

now, we are spinning the dreidel twice.

that means we have now 4×4 = 16 possible outcomes.

but we only want the outcomes, where the specified symbol is showing exactly once - either after the first spin or after the second spin.

so, out of the 16 possible combinations, we want only the ones, where the first spin delivered that result :

1 option on the first spin and 3 options (4 minus the already delivered result) on the second spin : 1×3 = 3.

and the ones, where the second spin delivered the result (but not the first). so, we have 3×1 = 3 options there.

that means we have 6 desired cases out of total 16 possible outcomes, and the probability is

6/16 = 3/8

mathematically we would simply say that the probability is the sum of

the probability of spinning it first combined with the probability of not spinning it second.

the probability of not spinning it first combined with the probability to spin it second.

that is

1/4 × 3/4 = 3/16

+

3/4 × 1/4 = 3/16

-----------------------

6/16 = 3/8

I don't know the options you can select, but I hope you understand the principles I explained. and I gave you the result and the way to calculate it.

so, hopefully you find the fitting options.
