Answer:
288
Step-by-step explanation:
the formula is 2(lw+wh+hl)
length - 8
width - 8
height 5
substitute the values and you get
2(64+40+40)
2(144)
= 288
Answer:
x = 10√3
Step-by-step explanation:
Because of the right angles, we can use Pythagoras
30² - x² = y² (a) Largest triangle
y² - 20² = h² (b) Medium triangle
substitute y² from (a) into (b)
30² - x² - 20² = h²
500 - x² = h² (d)
x² - h² = (30 - 20)² (c) smallest triangle
substitute h² from (d) into (c)
x² - (500 - x²) = 100
2x² = 600
x² = 300
x = 10√3
To start off with you need to get math-way it will help out
Using a calculator, determine the value of √101 to four or five decimal places. Do the same with 10π. We get { 9.92749, 10.0500, 0.99853, 31.4159}.
Arranging these in descending order, we get {10π, √101, 9.92749, 0.99853}.
You just plug in the x and y values
4(5) is greater than or equal to 3(6) + 2=
20 is greater than or equal to 20. so x=6 and y =5 is the answer. do you understand?
