Paisley has 8\tfrac{1}{4}8 4 1 ​ cups of yogurt to make smoothies. Each smoothie uses \tfrac{11}{16} 16 11 ​ cup of yogurt. How
Ivenika [448]

Given:

Total Yogurt = 8\dfrac{1}{4} cups

Yogurt required for each smoothie = \dfrac{11}{16} cup

To find:

The number of smoothies that Paisley can make with the yogurt.

Solution:

We know that,

\text{Number of smoothies}=\dfrac{\text{Total yogurt}}{\text{Yogurt required for each smoothie}}

Substituting the given values, we get

\text{Number of smoothies}=\dfrac{8\dfrac{1}{4}}{\dfrac{11}{16}}

\text{Number of smoothies}=8\dfrac{1}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=\dfrac{32+1}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=\dfrac{33}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=3\times 4

\text{Number of smoothies}=12

Therefore, the number of smoothies is 12.

Some girls in a Girl Scout troop are pairing up with some boys in a Boy Scout troop to practice square dancing. Two-thirds of th
Natalka [10]

Answer:

Fraction of the scouts are square dancing is \frac{19}{30}.

Step-by-step explanation:

Each pair  is one Girl Scout and one Boy Scout.

So,  to  the final fraction ( of the pairs) we are going to get 1/2 from the fraction of girls and 1/2 from the fraction of boys.  

Girls= \frac{2}{3} *\frac{1}{2} =\frac{2}{6}

Boys= \frac{3}{5} *\frac{1}{2} =\frac{3}{10}

To get the fraction of the scouts that are square dancing,  we have to add the fraction of girls ,  with the fraction of boys.  

=\frac{2}{6} +\frac{3}{10}

=\frac{(2*10) +(6*3)}{6*10} =\\ \frac{20+18}{60}

=\frac{38}{60}

=\frac{19}{30}

This means that  from 30 scouts ,  19 are dancing.

J = K (1+ p/100) make p as a subject
olganol [36]

Answer:

p = 100(J/K - 1)

Step-by-step explanation:

When we want to make a variable the subject of an equation, we want to get that variable by itself on one side of the equation - to unwrap it from all the operations attached to it.

Here's what the process looks like for p:

J=K(1+p/100)\\J/K=1+p/100\\J/K-1=p/100\\p=100(J/K-1)

At last week's track meet, Stacy ran 9/12 of a km, Jules ran 4/5 of a km, and Raul ran 3/4 of a mile. Which two students ran the
koban [17]

Answer:  No two students ran same distance

Step-by-step explanation:

Given

Stacy ran \frac{9}{12} of a km i.e.

\Rightarrow 1\times \dfrac{9}{12}=\dfrac{3}{4}=0.75\ km

Jules ran \frac{4}{5} of a km i.e.

\Rightarrow 1\times \dfrac{4}{5}=0.8\ km

Raul ran \frac{3}{4} of mile i.e.

\Rightarrow 1\times \dfrac{3}{4}=0.75\ miles\\\\\text{1 mile=1.6 km}\\\\\Rightarrow 0.75\ miles=1.2\ km

So, no two students ran the same distance.
