First set up a proportion
240/160 = 320/200
Cross multiply and if the left equals the right it is similar.
It is rounded to 20 because 23 is more closer to 23 than 30
For this case what we must do is take into account that the angle can be measured in two ways starting from the positive x axis.
- <em>1) Counterclockwise
</em>
- <em>2) Clockwise direction
</em>
We have then that the measures between both lines are given by:
1) Counter-clockwise: 90 degrees
2) Clockwise: -90-90-90 = -270 degrees
Answer
two possible measures of the angle below are:
-270 ° and 90 °
Answer:
D 216 pizzas
Step-by-step explanation:
if there expecting 1,088 I would say that's 56 pizzas
Answer:
Step-by-step explanation:
a) if the number of drill sold is plotted on the horizontal or x axis and the price of each drill sold is plotted on the vertical or y axis, the slope would be
m = (y2 - y1)/(x2 - x1)
= (40 - 50)/(3000 - 2000)
Slope, m = - 0.01
b)For every additional drill sold, the price per drill decreases by 0.01 cent
c) The equation of a straight line modelled in the slope intercept form is expressed as
y = mx + c
Where
m represents slope
c represents the y intercept
To determine the y intercept, we would substitute m = - 0.01, x = 2000, y = 50 into y = mx + c. It becomes
50 = - 0.01 × 2000 + c
50 = - 20 + c
c = 50 + 20 = 70
The equation modelling the situation is
y = - 0.01x + 70
Therefore, if the trend continues, the number of drills that would be sold for $43 is
43 = - 0.01x + 70
0.01x = 70 - 43 = 27
x = 27/0.01
x = 2700
2700 drills would be sold
