48 ten units and 1 five unit.
Answer:
√23
Step-by-step explanation:
When you are given two side lengths of a right triangle, you use the Pythagorean theorem to find the third side: a² + b² = c², where c is the hypotenuse (the longest side).
All you have to do is plug the given information in:
Remember, 13 is the hypotenuse for this triangle.
12² + b² = 13²
Simplify:
144 + b² = 169
Subtract 144 from both sides:
b² = 169-144
b² = 23
Square root both sides:
b = √23
And that's your answer!
Answer:
Option B
3.5 miles
Step-by-step explanation:
Considering the picture attached, the distance to Cascade Falls is written in mixed fraction and the question wants it expressed in decimal. 
is same as 1 divided by 2 which is 0.5 hence the fall is 3+0.5=3.5 miles
Answer:
D. Mathematical expressions for the relationships
Step-by-step explanation:
Quantitative analysis also called QA for short is the technique that tries to understand behaviour by using mathematical and statistical modeling, measurement and research. A quantitative analyst aims to represent a given reality in terms of numerical value. This can be achieved by using mathematical formulas and expressions to explain the relationships that exists between the variables. The data analyzed are usually gotten from polls and questionnaires or in general, well structured research instruments.
