Answer:
7 cm
Step-by-step explanation:
base area = (base length x base height)/2 = (2x6)/2 = 6 cm^2
height = V / base area = 42 / 6 = 7 cm
Answer:
Step-by-step explanation:
(19+2)/7
Answer:
67.5feet
Step-by-step explanation:
Given parameters:
Model distance between building and gymnasium = 22.5 inches
Scale of model : 1 inch = 3 feet
Unknown:
Actual ground distance = ?
To solve this problem, we first must understand the concept of scale. A scale is a relationship that represents a dimension on a map/model compared to the true ground expression. In order to visualize or represent some real life objects on paper or in a computer, we use models. These models are an abstraction of the real world based on scales. There are different ways of representing a scale.
In this problem;
the scale is given as;
1 inch on model represents 3 feet on ground
Now, to find 22.5 inches, simply cross multiply and solve;
If 1 inch on model represents 3 feet on ground
22.5 inches on a model will be = ![\frac{22. 5 inches x 3 feet }{1 inches}](https://tex.z-dn.net/?f=%5Cfrac%7B22.%205%20inches%20x%203%20feet%20%7D%7B1%20inches%7D)
= 67.5feet
Therefore, the actual distance is 67.5feet
Answer:
135°
Step-by-step explanation:
Draw a line that intersects the endpoint of the angle that is between L and K and is also perpendicular to L and K.
<em>∠a+45°+∠b = 180°</em>
<em>∠a+∠b = 135°</em>
Answer: B
