Answer:
P(compact cars) = 4/25 or .16
Step-by-step explanation:
<em>We know that there are </em><em>13 trucks, 8 vans, and 4 compact cars.</em>
<em />
<em>Let </em><em>P </em><em>denotes the probability of an event</em>
<em />
<em>Now we are asked to find the probability of compact cars</em>
<em />
<em>Number of favorable events = number of compact cars = 4</em>
<em />
<em>total number of outcomes </em><em>= 13+8+4 = 25</em>
<em>hence, P(compact cars) = number of favorable events/total outcomes</em>
<em> =4/25 or .16</em>
Answer:
85 degrees
Step-by-step explanation:
the sum of supplementary angles=180
155+ angle in the triangle=180
angle=180-155
angle=25 degrees
the sum of angles of triangle=180
25+60+x=180
85+x(inside triangle)=180
x=180-85
x=95
angle with (?):
the sum of supplementary angles=180
95+(?)=180
(?)=180-95
(?)=85 (An exterior angle of a triangle is equal to the sum of the opposite interior angles)
Answer:
1:Growth
2:Decay
3:Decay
Step-by-step explanation:
1 has all numbers above 1. 2 and 3 both have a number below 1, making it small.
Use the Pythagorean theorem:
Answer:
Step-by-step explanation:
There is only one figure in the attached image and the solution (surface area) is as follows:
The shape can be sub-divided into:
1. Rectangle
Dimension: 40 by 35
2. Rectangle
Dimension: 40 by 28
3. Rectangle
Dimension: 21 by 40
4. 2 triangles
Base: 21 and Height: 28
Calculate area of each and add them up to get the surface area of the figure.
1. Rectangle
Dimension: 40 by 35
2. Rectangle
Dimension: 40 by 28
3. Rectangle
Dimension: 21 by 40
4. 2 triangles
Base: 21 and Height: 28
So, the area is:
Factor out 40
