Answer:
£2.38
Step-by-step explanation:
Write and solve an equation of ratios:
£1.40 2.5 kg
----------- = ------------
c 4.25 kg
Cross multiplying, we get:
(£1.40)(4.25 kg) = (2.5 kg*c), or
(£1.40)(4.25 kg)
c = -------------------------- = £2.38
2.5 kg
, it is important to recognize that the point (x,y) in the first quadrant represents any
point on the semicircle. In Figure 2, the same semicircle is shown with the inscribed rectangle drawn for
three different values of x.
Answer:
=4
Step-by-step explanation:
y=-3x+4
y2-y1 divided by x2-x1 equals the slope. Then graph the line with the given points and the slope for the y-intercept.
Answer:
The lengths of the sides can be 10, 30 and 31. This would be a scalene triangle.
Step-by-step explanation:
In order to determine if it can create a triangle, we simple need to make sure that the value of one side is not greater than the other two added together. In this case, 10+30 > 31, which means it can be a triangle.
A triangle with no matching sides is called a scalene triangle. Therefore, we know it is a scalene triangle.
