Answer:
<h3>
126°</h3>
Step-by-step explanation:
given <abd = 48 and <dbc = 78, hence the addition rule is true<abc = <abd + < dbc
Substituting the given values inti the formula;
< abc = 48+78
< abc = 126°
The measure of angle abc is therefore 126°
1.20 could be a possibility...
Answer: Length = 40 inches
Width = 20 inches
Step-by-step explanation:
Let the width of the package be represented by x.
Since the length of the package must be twice its width, therefore the length will be: = 2 × x = 2x
Since the sum of the dimensions equals 60 inches. This will then be:
x + 2x = 60.
3x = 60
x = 60/3
x = 20
Therefore, the width = 20 inches
Length = 2x = 2 × 20 = 40 inches
The dimensions should be 40 by 20 inches.
Answer:
Step-by-step explanation:
we are given that A robot is expected to filter pollution out of at least 350 liters of air and water.
Also It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.
The inequality for number of minutes the robot should filter air (A) and water (W) to meet this expectations can be writte as follows:
Hence the required inequality has been formulated.
Answer:
0.143 to the nearest thousandth.
Step-by-step explanation:
7x = 1
To find the value of x be divide both sides of the equation by 7:
7x/7 = 1/7
x = 1/7
Converting to decimal:
1/7 = 0.1428571429.
