Answer:

A = 35 units

Step-by-step explanation:

The variable "b" represents the length of the triangle's base and "h" represents the highest height of the triangle. The area of a triangle can be determined using the formula:

A = 0.5bh

The area of the top triangle (including the isosceles triangle and the orange triangle) is:

A = 0.5 x (14 units) x (3 units + 5 units)

A = 56 units

The area of the isosceles triangle is:

A = 0.5 x (14 units) x (3 units)

A = 21 units

Thus, the area of the orange triangle is the area of both triangles minus the area of the isosceles triangle.

A = 56 units - 21 units

A = 35 units

Ad libitum [116K]

Answer:

The proportion of these light bulbs that will last less than the advertised time is 18.94% or 0.1894

Step-by-step explanation:

The first thing to do here is to calculate the z-score

Mathematically;

z-score = (x - mean)/SD

= (1500-1550)/57 = -50/57 = -0.88

So the proportion we will need to find is;

P( z < -0.88)

We shall use the standard score table for this and our answer from the table is 0.1894 which is same as 18.94%

Answer:

19.105 in if c is the hypotenuse

5.196 in if c is a leg

Step-by-step explanation:

The Pythagorean theorem is used for this.

If c is the hypotenuse, ...

... c² = 13² + 14² = 365

... c = √365 ≈ 19.105 . . . . in

_____

If c is a leg, ...

... 14² = 13² + c²

... c² = 196 -169 = 27

... c = √27 ≈ 5.196 . . . . in

lutik1710 [3]
First you have to get all the values on the other side of y. To do that subtract 2x, then divide the values on the right by 3. You will be left with y=3-2x/3.
