Explain how to compare numbers using place value ?

Answers

Place value is ones, tens, hundredths, thousandths.
I.e. 123.56

1 is in the hundreds place. 2 is in the tens place. 3 is in the ones place. And after the decimal you add -th to the end of the place value (tens->tenths). So 5 is in the tenths place (to the right of the decimal you skip the ones place). And 6 is the hundredth place. Hope this helps!

Find the area of the lateral faces of the right triangular prism with altitude of 5 cm and base edges of length 3 cm, 4 cm, and 5 cm.

Answers

Answer:
area of lateral faces = 60 cm²

Explanation:
The lateral area of the triangular prism can be calculated as follows:
lateral area = s₁h₁ + s₂h₂ + s₃h₃

We have:
h₁ = h₂ = h₃ = height of prism = 5 cm

Therefore, the formula became:
lateral area = h (s₁ + s₂ + s₃)

We area given that:
s₁ = 3 cm
s₂ = 4 cm
s₃ = 5 cn

Substitute with these givens in the above equation to get the lateral area as follows:
lateral area = 5 (3+4+5)
lateral area = 5(12)
lateral area = 60 cm²

Hope this helps :)

Solve for x:
3/4(3x+4)=4(x+6)

Answers

Answer:

Step-by-step explanation:

3/4 (3x + 4) = 4 (x + 6)

9x/4 + 3 = 4x + 24

9x/4 - 4x = 24 - 3

9x/4 - 4x = 21

multiply by 4 on both sides

9x - 16x = 84

-7x = 84

x = 84 / -7

x = -12

Answer:

-12
