PLEASE HELP!!!!! Geometry
barxatty [35]

Answer:

53°

Step-by-step explanation:

i will use ∩ to represent arc since there is no arc sign

if ∩EF = 34, then ∡EFC = 34

think of EFC as an angle in the larger circle

since EFC = 34, ABC = 34 because they are opposite angles and opposite angles are always congruent.

ABD = AB + BD = 19 + 34 = 53

Sheila has 11 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 3/4 pounds
Mice21 [21]

Hello!

<h2>Answer:</h2>

\boxed{ \bf Sheila~will~need~about~7~containers.}

__________________________________________________

<h2>Explanation:</h2>

First, we will need to convert the mixed fractions to improper fractions.

Numerators: (2 · 11) + 1 = 23

                      (4 · 1) + 3 = 7

Denominators: stay the same.

11 \frac{1}{2} ⇒ \frac{23}{2}

1 \frac{3}{4}  ⇒ \frac{7}{4}

Next, we must divide these two fractions:

\frac{23}{2} ÷ \frac{7}{4}

We must flip the divisor into a reciprocal:

\frac{23}{2} ÷ \frac{4}{7}

Change the division sign to multiplication and multiply:

\frac{23}{2} × \frac{4}{7} = \frac{92}{14}

To find out how many containers will be needed, simply convert this fraction to a decimal by dividing the numerator by the denominator.

92 ÷ 14 = 7 (Rounded)
