Answer:

x = 16

Complete the statement about the square pyramid shown below.x 5

Is x greater than 5 less than 5 or equal to 5?

Answers

Answer:

x > 5

Step-by-step explanation:

We know:

If a, band care length of sides of a triangle, then

a + b > c

a + c > b

b + c > a

We have a = x, b = x, c = 10.

Substitute:

x + x > 10

2x > 10       divide both sides by 2

2x : 2 > 10 : 2

x > 5

Answers

For the measurements in the manual that Juan should ask for at the hardware store: 1 1/8" screed bars: a) 24mm, 1 1/4 in. screed bars: d) 35 mm, and 1/2 in. screed bars: b) 0.4375 in.

What are the correct measurements?

  • The measurement 1 1/8 in is equivalent to 1.125 inches. Among the given options, the closest measurement is 0.933 in, which is the best choice.
  • The measurement 1 1/4 in is equivalent to 1.25 inches. Among the given options, 1.375 in is the closest measurement.
  • The measurement 1/2 in is equivalent to 0.5 inches. Among the given options, 0.4375 in is the closest measurement. This is because 1/2 in can also be represented as 8/16 in, and 0.4375 in is the equivalent in decimal form.
