The price of an item has been reduced by 70% the original price was $58 what’s the price of the item now ¿

Mamont248 [21]

Answer:$17.40

Step-by-step explanation:

This is a very simple question. First since 70% is the amount of money removed, we do 100-70=30

30% is the price that remains. Change that into a fraction 30/100 and then multiply the original cost

30/100*58=17.4

The answer is $17.40

Write the quadratic equation in standard form:<br> 7x + 8 + 2x2<br> 2x + 1 + x2

JulsSmile [24]

Answer:

$3x^2 + 9x +9$

Step-by-step explanation:

Given

$(7x + 8 + 2x^2) + (2x + 1 + x^2)$

Required

The result in standard form

We have:

$(7x + 8 + 2x^2) + (2x + 1 + x^2)$

Remove brackets

$7x + 8 + 2x^2 + 2x + 1 + x^2$

Collect like terms

$7x+ 2x + 8 + 1 + 2x^2+ x^2$

$9x + 9+ 3x^2$

The standard form of a quadratic equation is:

$ax^2 + bx + c$

So, we have:

$9x + 9+ 3x^2$

$3x^2 + 9x +9$

Urgent!!!! not worried about a but i need b and #4

Oksi-84 [34.3K]

b) The surface area is 564.5. Picture below.

4. Three possibilities.

Formula for volume of a cylinder: πr^2h

Formula for volume of sphere: 4/3πr^3

If the radius of the sphere is 1 inch than the volume is: 4.18879 or 4.19 rounded.

I used substitution on this website https://www.omnicalculator.com/math/volume

Just plug in the 4.18879 at the cylinder volume and put in a random number in the radius or height whichever you want then it'll give you the one you left blank. You'll find three possibilities for the radius and height of 4.18879 volume.
