1. $1.23 per pair
A dozen is 12 so you do 12x7=84

Then you do 103.32 divided by 84 which gives you 1.23

2. His error was doing 103.32 divided by 7 because he thought it was only 7 pairs but it’s 7 dozen.

Angle $eab$ is a right angle, and $be = 9$ units. what is the number of square units in the sum of the areas of the two squares

Alla [95]

Let the measure of side AB be x, then, the measue of side AE is given by

$AE=\sqrt{9^2-x^2}$ .

Now, ABCD is a square of size x, thus the area of square ABCD is given by

$Area=x^2$

Also, AEFG is a square of size $\sqrt{9^2-x^2}$ , thus, the area of square AEFG is given by

$Area=\left(\sqrt{9^2-x^2}\right)^2=9^2-x^2=81-x^2$

The sum of the areas of the two squares ABCD and AEFG is given by

$x^2+81-x^2=81$

Therefore, the number of square units in the sum of the areas of the two squares ABCD and AEFG is 81 square units.

Answer:

SAS (side-angle-side)

Step-by-step explanation:

In the given picture, it is shown that the triangles have two congruent sides, and one congruent angle between them. The congruent sides are shown by the lines on the sides. The congruent angle is shown by the box outlining the angle (technically a box outlining the angle demonstrates that the angle is a right angle, either way, it proves the congruency).

3-14 plzzz except #13 20 points!

Marianna [84]

#3: 15

#4: 13.2

#5: 5.44 (curious as to how you guessed 7)

#6: 7

#7: 7.3

#8: 15

#9: You'd round 0.9 to 1 and 3.78 to 4. 4/1 = 4

#10: Round 2.5 to 3. 36/3 = 12

#11: If they want you to round 0.25 down to 0, then 7/0 is undefined.

#12: 9.5 rounds to 10 142.5 rounds to 143. 143/10 = 14.3

#14: 24.8 cm divided by 175 = approximately 0.1417 cm per year. Round that up to approximately 0.14 per year.

If three-quarters of the pizza provided 12 pieces on the table, how many pieces were in the pizza when it was full?

Anna71 [15]

Take 12 and divide it by 3 to get the number of slices per quarter. Then multiply the answer you got by four. The answer is 16.
