Determine whether the pair of solids are similar, congruent, or neither. figures are not necessarily drawn to scale.

They are similar but not congruent.

the two shapes are similar, because they are both pyramids with the same ratio of dimensions.

But they are not congruent because the ratios are not equal to 1.

Step-by-step explanation:

Using the shapes in the attached image we want to confirm if they are similar or congruent.

From the image we can see that they are both pyramids

To compare the two pyramids

Pyramid 1

Height h = 8.4mm

Length l = 9.0mm

Breadth b = 7.2mm

Pyramid 2

h = 7mm

l = 7.5mm

b = 6mm

For the two pyramids to be similar, the sides must have the same ratio.

For the two pyramids to be congruent, the ratio of their dimensions must be equal to 1

Ratio

h = h1/h2 = 8.4/7 = 1.2

l = l1/l2 = 9/7.5 = 1.2

b = b1/b2 = 7.2/6 = 1.2

Therefore the two shapes are similar, because they are both pyramids with the same ratio of dimensions.

But they are not congruent because the ratio is not equal to 1.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

the first one

step-by-step explanation:

just id the test.
