Answer( angle b) = 41.82 °
Answer:
10%
Step-by-step explanation:
Amount of salt in 90g of water = 10g
Total weight of solution (salt + water) = (10g + 90g) = 100g
=> Total weight of salt in 100g of solution = 10g
Hence, Percentage of salt in this solution is given by:
This corresponds to 10%
So the percentage of salt in the solution = 10%
Similarly, percentage of water in the solution = = 90%
A zero has a "multiplicity", which refers to the number of times that its associated factor appears in the polynomial. For instance, the quadratic (x + 3)(x – 2) has the zeroes x = –3 and x = 2, each occuring once.
Answer: B = 70°, b = 29.2; c = 29.2
Step-by-step explanation:
sum of angles in a triangle is 180
40+70 +X = 180
X is the last angle
110+x=180
x= 180-110 =70
A= 40°
B= 70°
C= 70°
the triangle is Isosceles triangle meaning two sides are equal , angle B = angle C
Given:
Length of garden = 21 ft
Width of garden = 32 ft
Let l be the length and w be the width.
Area of the rectangular garden = l x w = 21 x 32 = 672ft²
Now since the length is 21 ft, the path is 3 ft, add 3 ft to both
