Solve the equation x² = 1.21 *

gogolik [260]

Answer:

x = 1.1, -1.1

Step-by-step explanation:

This is the answer because:

1) Take the root of both sides and solve.

$\sqrt{1.21}$ = 1.1

2) x can also equal -1.1 because -1.1 times -1.1 gives us a positive 1.21 because negative x negative = positive

Hope this helps!

Help please I’m just not good at this and. Get really confused when putting things in standard form. Use two points on the line

frez [133]

Answer:

From the graph, the slope is -4/5 and the y-intercept is 4 so the slope-intercept equation is y = -4/5x + 4. To convert to standard form we'll do:

y = -4/5x + 4

5y = -4x + 20

4x + 5y = 20

John has a storage bin in the shape of a rectangular prism the storage bed is still in the and 1/2 ft long 2 ft wide and 2 ft ta

Phoenix [80]

We know, volume of rectangular prism is given by :

$V = lbh\\\\V=\dfrac{1}{2}\times 2\times 2\ ft^2\\\\V=2\ ft^2$

Volume of cubic box :

$v=a^3\\\\v=(\dfrac{1}{2})^3\ ft^3\\\\v=\dfrac{1}{8}\ ft^3$

Number of cubes can be filled :

$N=\dfrac{V}{v}\\\\N=\dfrac{2}{\dfrac{1}{8}}\\\\N=16$

Therefore, 16 cubes can be put in the bin.

Hence, this is the required solution.
