Aaron found rhe length of the diagonal of a rectangle to be an irrational number. What could be the lenght of the diagonal

Amanda [17]

Answer:

See below

Step-by-step explanation:

It could be a positive square root l like √10 ( the number not being a perfect square).

He would have obtained this value from the application of the Pythagoras theorem. For example the length and width of the rectangle might have been 3 and 1 foot respectively, so the diagonal would have length √(3^2 + 1^2) = √10.

He could give an estimate of the length to nearest hundredth using his calculator. This would be 3.16 feet.

What is the area of the base of a triangular prism if the volume is 210 ft3 and the height is 14 ft?

Oksi-84 [34.3K]

We have the area of the base of a triangular prism= a*b
the volume of triangular prism =a*b*c( where c is the height) so that 210=a*b*14 ==> 210= base area*14==> base area= 210/14

Which graph represents the following system of equations y=3x+3 y=-x-3

emmasim [6.3K]

Answer:

See picture attached below.

Step-by-step explanation:

To graph the system, graph each line separately.

y = 3x + 3 ha slope 3 and y-intercept 3.

Start at 3 on the y-axis and mark a point. Then from this point move up 3 units and to the right 1 unit. Mark a point and connect.

y=-x - 3 has slope -1 and y-intercept -3.

Start at -3 on the y-axis and mark a point. Then from this point move down 1 unit and to the right 1 unit. Mark a point and connect.

This graph is represented in the picture attached.
