Which three lengths could be the lengths of the sides of a triangle? 13 cm, 5 cm, 18 cm 21 cm, 7 cm, 7 cm 8 cm, 23 cm, 11 cm 9 c
Alexeev081 [22]
We can solve this problem using the Triangle Inequality property. The Triangle Inequality property states that the sum of two sides of a triangle will always be greater than the third. That being said, the only answer that works is the last one, which has the answer of 9 cm, 15 cm, and 22 cm.

A student sets up the following equation to convert a measurement. Fill in the missing part of the equation
fomenos

Answer:

We have the equation:

(14 N/mm)*X = Y N/cm

So we want to transform 1/mm to 1/cm.

We know that:

10mm = 1cm

1 = 10mm/1cm (we want to have mm on the numerator, so it cancelates with the mm in the denominator)

then the conversion is from 1/mm to 1/cm is:

X = 10mm/cm

then we have:

(14N/mm)*(10mm/cm) = 140 N/cm

A 3 by 3cm grid shows nine 1 by 1 cm squares and uses 24cm of wire.
zalisa [80]

Answer:

840 cm

Step-by-step explanation:

Given that in the question we have, : 9, 1 cm × 1 cm squares setting a 3 × 3 grid.

Therefore wire required in 3 x 3 grid is

3(3+1) + 3(3+1)

= 3 × 4 + 3 × 4

= 24 I'm

Similarly, the length of the wire required in 20 by 20 grid will be

=> 20(20+1) + 20(20+1)

=> 20 × 21 + 20 × 21

=> 420 + 420

= 840cm
