Answer: 6.75
Step-by-step explanation:
|6.75| = the absolute value of 6.75. The absolute value of a number is its distance from 0, which will always be positive. So |6.75| = 6.75.

Answer: The length of the field is 98m. The width of the painting is 87cm
Step-by-step explanation: To find the length we must remember that the area formula is length x width so all we must do is divide the area by the width. To find the width of the painting you have to subtract the two length sides from the perimeter and then divide the number found by 2. 99x2= 198 372-198=174 174/2=87
The number of squares of whole pita bread Min will have to cut up is;
<u><em>21 squares of whole pita bread</em></u>
- Since the triangle is isosceles, and has base of 4 cm with 2 equal sides of 6 cm, it means the height is 5.7 cm.
- Thus, area of triangle is;
A = ¹/₂ × 4 × 5.7
A = 11.4 cm²
- She will cut 3 pita triangles for every guest. This means that;
Area for each guest = 3 × 11.4 = 33.2 cm²
- There are 250 guests and so the total needed for the 250 guests is;
Total area = 250 × 33.2
Total area of pita bread = 8300 cm²
- The bread comes in 20 cm sides of a square shape.
Area of square = 20 × 20 = 400 cm²
- Number of squares of whole pita bread she will have to cut = 8300/400
⇒ 20.75 ≈ 21 squares of whole pita bread

Answer:
<em>Sin 400° = Sin 40°</em>
Step-by-step explanation:
We have to find the value of the trigonometric function <em>Sin 400°</em>
Here,
Sin 400° = Sin (360° + 40°)
The picture shown below shows that in 1st quadrant <em>All trigonometric functions( Sin, Cos, Tan, Cosec, Sec, Cot ) </em> are positive.
And <em>Sin(360° + Ф°) = Sin ( Ф°)</em>
= Sin ( 40°)
Therefore, <em>Sin 400° = Sin 40°</em>
