Answer:
1 Meter is equal to 100 centimeters.
Step-by-step explanation:
If you would like to know how many centimeters of ribbon does Audrey need, you can calculate this using the following steps:
1 meter = 100 centimeters of yellow ribbon
28 centimeters of blue ribbon
100 cm + 28 cm = 128 cm
Result: Audrey needs 128 centimeters of ribbon.
Draw an equilateral triangle FGH so that FH is the horizontal base. Draw a vertical line GR from G to line FH to represent the height of the triangle.
Let a = length of a side of the equilateral triangle (all sides are equal).
Each angle is 60° because the three angles add up to 180°.
Let h = GR, the height of the triangle.
Because the triangle is equilateral, triangle FGR is a right triangle, with
m∠F = 60° ,
m∠R = 90°,
FG = a.
By definition,
sin(F) = h/a
That is,
h = a*sin(F) = a*sin(60) = a*(√3/2).
Answer:
The height of the equilateral triangle is (a/2)√3,
where a = length of a side of the triangle.
Answer:
(x - 8)(x + 7)
Zeroes: x = 8, x = -7
Step-by-step explanation:
Find factors of -56 that add to -1.
-8 and 7
The factored form is:
(x - 8)(x + 7)
The zeroes for this polynomial are x = 8 and x = -7
