Answer:

The required equation is \frac{y}{6} =2.

Step-by-step explanation:

Consider the provided information.

Write a division equation that has a solution of 12.

The required division equation is shown below:

\frac{y}{6} =2

Solve the above equation a shown.

\frac{y}{6}\times 6=2\times 6

y=12

Now check this with algebraic method.

The required tape diagram is shown below:

\frac{12}{6} =2

2=2

Which is true, Hence 12 is the correct answer.

Fran need to move $9 million out of the country. The dimensions of a US bill is 2.61 inches by 6.14 inches by 0.0043 inches.
Mice21 [21]

Answer:

  • 1728 in³ in a cubic ft
  • 3.6 cubic feet (rounded to tenths)
  • 2 suitcases

Step-by-step explanation:

For part 2, you have rounded to hundredths. The question asks for the answer rounded to tenths.

__

<u>Part 3</u>

  (3.6 ft³)×(1 suitcase)/(2.9 ft³) = 3.6/2.9 suitcases ≈ 1.24 suitcases

Suitcases only come in whole numbers. 1 is too few, so 2 suitcases are needed.

In triangle OPQ, p = 38 cm, q = 29 cm and Angle O=39º. Find the length of o, to the nearest
Lisa [10]

Answer:

The length of o is 24 centimeters

Step-by-step explanation:

In Δ OPQ

∵ Side p is opposite to ∠P

∵ Side q is opposite to ∠Q

∵ Side o is opposite to ∠O

→ To find side o we must use the cosine rule

∴ o = \sqrt{p^{2}+q^{2}-2(p)(q).cos(O)  }

∵ p = 38 cm

∵ q = 29 cm

∵ m∠O = 39°

→ Substitute them in the rule to find o

∴ o = \sqrt{(38)^{2}+(29)^{2}-2(38)(29).cos(39)}

∴ o = 23.92008154

→ Round it to the nearest centimeter (whole number)

∴ o = 24 centimeters

∴ The length of o is 24 centimeters

Given that 196k is a perfect cube , find the smallest possible value of k
kaheart [24]
Factor 196k
196k=2*2*7*7*k
we need to get something like x^3
hmm
we right now have
(2*7)^2
if we multiply that by (2*7)^1, we can beg (2*7)^3,
therefor k=2*7=14

tha tnumber is 14

or

if k can be any number
k can be 1/196, to make it 1, and 1 is a perfect cube

or

my bro had an epic idea: what if k is negative
the cube root of a negative number is negative
so the smallest one would be negative infinity or something



I think the answer you're looking for is k=14
