Answer:

1/105

Step-by-step explanation:

Total Marbles= 2+6+7=15

2/15 * 1/14 = 2/210 = 1/105

(It becomes 1/14 since you take out own red marble)

Which number line shows the correct placement of 20%, 1/3, and 2/3?
BigorU [14]

Answer with Step-by-step explanation:

We are given that

20%

When we change percent into fraction we will divide the percent by 100

\frac{20}{100}=\frac{1}{5}

\frac{1}{3}

\frac{2}{3}

We have to find the line which shows the correct placement of given numbers.

Lcm(3,5)=15

\frac{1\times 3}{5\times 3}=\frac{3}{15}

\frac{1\times 5}{3\times 5}=\frac{5}{15}

\frac{2\times 5}{3\times 5}=\frac{10}{15}

A box company is designing a new rectangular gift container. The marketing department has designed a box with a width 2 inches s
Sladkaya [172]
Volume of the box= <span>56 cubic inches
let x is the length, then
width =</span><span>2 inches shorter than its length = x - 2
</span>height =  <span>3 inches taller than its length = x+3
Volume = length x width x height
56 = x x (x-2) x (x+3)
56 = (x</span>² -2x)(x+3)
56 = x³ +3x² -2x² - 6x
56 = x³ + x² -6x
x³+x²-6x-56 = 0
using the rational root theorem and factoring the polynomial;
(x-4)(x² +5x +14) = 0
from here;
x-4 = 0
x = 4
So, length = 4 inches
width = x - 2 = 4 -2 = 2 inches
length = x + 3 = 4 + 3 = 7 inches
volume = l x w x h = 4 x 2 x 7 = 56

Using all the rest of my points on this all just here for points answers will be reported
Semenov [28]
So the volume of the cylinder = pi r^2 * h
Height = 4 feet tall
Radius = 1 foot
So just do pi * 1^2 * 4
3.14 x 1^2 x 4 = 12.56 cubic feet
