Answer:

Step-by-step explanation:

here's why:

whenever you multiply a number by 100, you can solve it easily by adding two 0s to the end of that number and that is the answer. In this case, the answer is 636,300.

Lets check this answer:

636,300 divided by 100= 6363, so we know this is correct.

I need help with number 1

irina1246 [14]

Distribute
8-2t-2=-3t+1

Combine like terms
-2t+6=-3t+1

Add 3t to both sides
t+6=1

Subtract 6 from both sides
t=-5

Final answer: t=-5

A cone has a radius of 4 units and a height of 6 units. Its volume is (A. 96 / B. 100.48 / C. 301.44 / D. 401.92) cubic units. I

Fed [463]

Answer:

<h2>A cone: B. V = 100.48 cubic units</h2><h2>A cylinder: C. V = 301.44 cubic units</h2>

Step-by-step explanation:

The formula of a volume of a cone:

$V=\dfrac{1}{3}\pi r^2H$

<em>r</em> - radius

<em>H</em> - height

We have <em>r = 4 u</em> and <em>H = 6 u</em>. Substitute:

$V=\dfrac{1}{3}\pi(4^2)(6)=\dfrac{1}{3}\pi(16)(6)=\dfrac{1}{3}\pi(96)=32\pi\ u^3$

$\pi\approx3.14\to V\approx(32)(3.14)=100.48\ u^3$

If the cylinder has the same radius and height as a cone, then the volume of the cylinder is three times larger than the volume of the cone.

Therefore, the volume of acylinder:

$V\approx3(100.48)=301.44\ u^3$

Why?

The formula of a volume of a cone:

$V_{cone}=\dfrac{1}{3}\pi r^2H$

The formula of a volume of a cylinder:

$V_{cylinder}=\pi r^2H$

Therefore

$V_{cone}=\dfrac{1}{3}V_{cylinder}\to V_{cylinder}=3V_{cone}$

If the radius and height are the same.

The square of a negative number is twenty-eight more than three times the negative number. Find the number.

MAXImum [283]

The number is x

it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero

x-7=0
x=7
this is not the answer because we were told the number was negative

x+4=0
x=-4
correct

the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check

the number is -4
