B Fragments of the Earths Crust that float on the Earths Mantle

Delvig [45]2 years ago

Answer:

Step-by-step explanation: Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

Please help me with this and find x!! Thank you, only if you know!

scoray [572]

Answer:

x = 9.8

Step-by-step explanation:

to find x, use pythagorean theorem

$a^{2} = c^{2} - b^{2}$

$a^{2} = 14^{2} - 10^{2}$

$a^{2} = 196 - 100$

$a^{2} = 96$

$\sqrt{a^2} = \sqrt{96}$

$a = 9.7979$ ⇒ 9.8

Nine yards of ribbon are cut into 8 equal pieces what is the length of each piece of ribbon. Write a division expression to repr

PSYCHO15rus [73]

Answer:

$x=\frac{9}{8}\ yards$

$x=1.125\ yards$

Step-by-step explanation:

Let's call x the length of each piece in yards

If the ribbon is cut into 8 equal pieces then the sum of the pieces is:

$x+x+x+x+x+x+x+x=8x$

Then:

$8x=9\ yards$

Now we solve the equation for x

$8x=9\ yards$

Divide both sides of equality by 8

$\frac{8}{8}x=\frac{9}{8}\ yards$

$x=\frac{9}{8}\ yards$

So the length of each piece is $\frac{9}{8}$ of a yard.

This is: 1.125 yards

Help, my daughter is learning about finding lengths of unknown sides. I have no idea how to help on these three homework problem

Lyrx [107]

BC = 4
GE= 23
QR = 7
TR = 11
BD = 22
FG = 6

explanation: you have to look at the numbers at the opposite side of where it’s asking, for example the first one; on the opposite side of BC it’s 12 and other side is 8 and you have to find the space in between so to find BC you would have to subtract 12-8 and you’ll get 4
basically a bunch of subtraction and addition, just look at the numbers on the opposite side. hope this helps !
