Answer:
The answer is 70.
Step-by-step explanation:
Ratio of cars per hour is 5:1
For every hour, they wash five cars. Multiply 5 times 7. That equals 35. That's 35 cars per day. Now they're asking for 2 days. Multiply 35 by 2 (because of the 2 days) and you get 70 cars.
Answer:
2x<15
Step-by-step explanation:
>= greater than
<=less than
To solve:
2x<15
÷ 2 ÷2
x< 7.5 or 7 1/2

Answer:
y=5/6 x+5
Step-by-step explanation:
First look at the y axis, you'll see that the line passes 5 which is B. Then use Rise/Run (5/6) to find points to find M
then plug it in the equation y=mx+b
Answer:
Step-by-step explanation:
First, let us find the gradient of AB:
Gradient of AB =
=
We also need to know that The <em>product of gradients which are perpendicular to each other is -1</em>. Using this idea, we can find the gradient of the perpendicular bisector:
(Gradient of perpendicular bisector)( ) = -1
Gradient of perpendicular bisector =
Now, we need to know at which coordinates the perpendicular bisector intersects AB. <em>A perpendicular bisector bisects a line to two equal parts</em>. Hence the <em>coordinates of the intersection point is the midpoint of AB</em>. Thus,
Coordinates of intersection = ( , )
= ( 2, 1 )
Now, we can construct our equation. The equation of a line can be formed using the formula where is the gradient and the line passes through . Hence by substituting the values, we get:
