Mathematics

Ad libitum [116K]2 years ago

Answer:

x = 15

Step-by-step explanation:

We are told that a right angle is divided into two parts

A right angle = 90°

Part A = 30°

Part B = 4x

Hence:

30° + 4x = 90°

Collect like terms

4x = 90° - 30°

4x = 60°

4x = 60/4

x = 15

Therefore, the value of x = 15

A milloniare estimates her wealth to be $2.2×10 to the nearst million dollars.what are the lower and upper bounds for the millio
Ostrovityanka [42]

Answer:

Lower bound=$2.15×10

Upper bound=$2.25×10

Step-by-step explanation:

A milloniare estimates her wealth to be $2.2×10 to the nearst million dollars.

In other words, his worth is $22 to the nearst million dollars.

To find the lower bound of the millionaire's wealth, we divide the level of precision by 2 and subtract from the millionaire's wealth.

Lower bound= 22-0.5=21.5 million dollars.

To find the upper upper bound, we add half of the level of precision to her estimate.

Upper bound =22+0.5=22.5 million dollars
