Answer:

(a)7 Customers

(b)\frac{3}{4} Hour

Step-by-step explanation:

The Time Customers Waited for Food (in hours) are given as: \frac{1}{2},\frac{1}{4} , \frac{3}{4} , \frac{1}{2} , \frac{1}{4} , \frac{1}{2} , 1

(a)To determine the number of customers on which the food critic collected data, we simply count the information recorder on the length of time the customers waited.

Number of Customers on which the food critic collected data =7

(b)Next, we are required to find the difference in the longest and shortest time that customers waited.

From the given data: \frac{1}{2},\frac{1}{4} , \frac{3}{4} , \frac{1}{2} , \frac{1}{4} , \frac{1}{2} , 1

Longest Time = 1 Hour

Shortest time = \frac{1}{4} hour

The Difference in time

=1-\frac{1}{4}\\\text{Taking LCM}\\=\frac{4-1}{4}\\=\frac{3}{4} hour

8 11/15= 7 ?/15 help me
just olya [345]

Answer:

7 \frac{26}{15}

Step-by-step explanation:

8 \frac{11}{15} = 7 \frac{?}{15}

Remember the multiply and add rule or improper fractions. To convert from a mixed number to an improper fraction, one must multiply the number part of the mixed number by the bottom (denominator) on the fraction. Then one must add that to the numerator (top) of the fraction. Since 7 is 1 less than 8, then one would have to multiply 15 by 1, and add it to 11, to get the value on top of 7 \frac{?}{15} The value would be;

7 \frac{26}{15}

Need help badly<br><br> #15 Find the area of each sector.
Ber [7]

The highlighted sector is exactly 3/4 of the circle area, because \frac{3\pi}{2} is 3/4 of 2\pi which is a complete rotation.

Since you are given the radius, you can compute the area as

A = \pi r^2 = 16\pi

So, 3/4 of this area would be 12\pi squared cm.

The remaining sector, of course, is 4\pi squared cm.
