Answer:

ans = 9 degree

Step-by-step explanation:

81 + (4x) + (5x+18) = 180 (The sum of all angles of triangle is 180 degree)

81 + 4x + 5x + 18 = 180

99 + 9x = 180

9x = 180 - 99

9x = 81

x = \frac{81}{9}

x = 9 degree

When Mrs. Stewart makes pie dough, she uses 2/3 cup of shortening for every 2 1/2 cups of flour which proportion could be used t
zloy xaker [14]

Answer:

The amount of flour Mrs.Stewart needs for 5 cups of shortening =\frac{75}{4} =18\tfrac{3}{4} cups.

Step-by-step explanation:

Mrs.Stewart pie dough needs  \frac{2}{3} cups of shortening for 2\tfrac{1}{2}=\frac{5}{2} cups of flour.

Now we assume that the shortening needed for x cups of flour is y cups.

Accordingly we can arrange the ratios.

So for one cup of shortening how many cups of flour is needed we have to use the unitary method:

\frac{cups\ of flour\ (x)}{cups\ of\ shortening\ (y)} =\frac{x}{y} =\frac{5/2}{2/3}

Plugging the value of y=5 as it is number of cups of shortening Mrs.Stewart have used.

And multiplying both sides with 5.

Number of cups of flour needed when 5 cups of shortenings are used (x) =\frac{x}{y} =\frac{5/2}{2/3}.

So, (x)=\frac{5\times 3\times 5}{2\times 2} =\frac{75}{4} = 18\tfrac{3}{4}

The amount of floor Mrs.Stewart needed for 5 cups of shortening = 18\tfrac{3}{4}\ cups of floor.

Each week carrie works 40 hours she spend 15% of her time at register
VLD [36.1K]
Please, share the goal of the problem.  If Carrie works 40 hours per week and spends 15% of her time at the register, how much time does she NOT spend at the register?  

Subtract 15% from 100%; the result is 85%.  Now find 85% of 40 hours:

0.85(40 hours) = 34 hours.

Please note that I invented part of this problem.  Next time, share all of the info so that someone can help you solve YOUR particular problem.

The school auditorium has 900 seats. The inequality, with x representing adults and y representing children, can be solved to fi
Paha777 [63]

Answer:

Step-by-step explanation:

The ordered pair is located on the boundary line of the graph of the inequality, and because the sign is "less than or equal to", the values on the boundary line are also included in the solution set.

Looking at this logically, we also see that it certainly possible for half the seats to be occupied by adults and half by children.
