If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.
p(70/100)=210 multiply both sides by 100
70p=21000 divide both sides by 70
p=300
So there are 300 photographs in all.
Answer:
So, gradient is 2.
Step-by-step explanation:
Here Let's take points (3,4) and (4,6)
so
gradient(m) = (y2-y1)/(x2-x1)
= (6-4)/(4-3)
= 2/1
Answer:
Step-by-step explanation:The prism has 9 edges; the bases of the prism are triangles; and the prism has 5 faces.
Step-by-step explanation:
The bases of a prism are the faces that are parallel. In this prism, the only faces that are parallel are the two triangles. This means the bases are triangles.
In addition to the two parallel bases, there is a are three faces that join the sides of the bases. This makes a total of 2+3 = 5 faces.
The edges are where the faces meet. There are 3 edges around each base; this is 6. There are also 3 edges connecting the lateral faces; this makes 6+3 = 9 edges.
