How to do triangle equation ​

Mathematics
1 answer:
zimovet [89]3 years ago
3 0

Answer:

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

tester [92]

Answer:

7 / 16

Step-by-step explanation:

Sample space is attached below :

Theoretical Probability of any event A

P(A) = (number of required outcome / Total number of possible outcomes)

Required outcome = sum greater than 7 = 14

Total number of possible outcomes = 32

P(sum greater than 7) = 14 / 32

P(sum greater than 7) = 7 / 16

The velocity-versus-time graph for a shuttle bus moving along a straight path is shown in Figure 13. b. Identify the time interv
elena-14-01-66 [18.8K]
Since the Figure is not given let me answer the items above by concept. 
(b) The intervals during which the acceleration of the bus is constant is the portion where the graph is a line that is neither horizontal or vertical. 

(c) The area bounded by the curve and the x-axis is the distance. To get the average velocity, determine the total distance and divide by the total time interval.
 
(d) The acceleration is determined by calculating the differences between velocities and dividing this difference by the difference of time interval.

A school wishes to form a rectangular playground using 160 meters of fencing. The playground borders the school building, so the

Answer:

A(x)=80x-\dfrac{x^2}{2}

Step-by-step explanation:

Let the length of the school be x meters (this is also the length of playground) and the width of playground be y meters.

A school wishes to form a rectangular playground using 160 meters of fencing (two widths and one length must be fenced). So,

x+2y=160\\ \\2y=160-x\\ \\y=80-\dfrac{x}{2}

A function that gives the area of the playground in terms of x is

A(x)=\text{Length}\times \text{Width}\\ \\A(x)=y\times x\\ \\A(x)=\left(80-\dfrac{x}{2}\right)\times x\\ \\A(x)=80x-\dfrac{x^2}{2}
