Answer:
x = 30
Step-by-step explanation:
if A||B, then 4x + 2x must equals to 180 (interior angles of 2 parallel lines)
6x = 180
x = 30
Answer:
centimeter square.
Step-by-step explanation:
We are given that,
Number of rows having squares = 5
Length of each square = x cm
As, we know,
Area of a square =
Thus, area of 1 square =
<em>As there are x squares in each row</em>, we get,
Area of 'x' number of squares = =
<em>Also, as there are 5 rows.</em>
Thus, total area of 5 rows = = centimeter square.
Hence, the required area is centimeter square.
Answer:
The appropriate measure is cm/day.
Step-by-step explanation:
The best unit to measure the height of a plant = cm.
The best measure for time is day.
Rate refers to the ratio between units. Mostly, the difference in some unit when time passes.
She can measure the height of the plant in each day.
Hence, the appropriate unit for Dalla is cm per day.
Answer:
b. m = 2, b = 4
Step-by-step explanation:
y = mx + b
m = slope and b = y-intercept
The slope is 2 cause it's going up 2 squares while only going to the right one square each time, so u could right 2/1 but it's not necessary so just 2. And the intercept is 4 because that's where the line intercepts the y-axis.
