Answer:
140%
Step-by-step explanation:
To write a percentage we need a number over 100.
We can first set up two ratios:
We can solve using cross multiplication (multiply the numerator of the first fraction with the denominator of the second fraction and multiply the numerator of the second fraction with the denominator of the first fraction)
3500=25x
Divide both sides by 25 to isolate x
x=140
140%
Answer:
Step-by-step explanation:
a). By applying Pythagoras theorem in right triangle ABC,
AC² = AB² + BC²
20² = 16² + BC²
BC =
= 12
Therefore, another leg of the triangular base = 12 cm
Area of the triangular base ABC =
=
= 96 cm²
Volume of a triangular prism = Area of the triangular base × height
960 = 96 × b
b = 10 cm
b). Area of the triangle ABC = 96 cm²
Zeros of this function are not real, this is because if we’re using the quadratic formula our discriminant has to be positive to produce any real number as a solution. In this case our discriminant is -4 using the formula B^2-4AC.
The answer is 20
