Answer:

486 centimeters³

Step-by-step explanation:

Surface area of a cube = 6s²

Where,

s = side length

Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.

s = 9 centimeters

Surface area of a cube = 6s²

= 6 × 9²

= 6 × 81

= 486 centimeters³

Surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters 486 centimeters³

Answer:

y=34x−8

Step-by-step explanation:

Answer:

x = - 2, y = - 2

Step-by-step explanation:

Given the 2 equations

y = 2x + 2 → (1)

4x - y = - 6 → (2)

Substitute y = 2x + 2 into (2)

4x - (2x + 2) = - 6 ← distribute and simplify left side

4x - 2x - 2 = - 6

2x - 2 = - 6 ( add 2 to both sides )

2x = - 4 ( divide both sides by 2 )

x = - 2

Substitute x = - 2 into (1) and evaluate for y

y = 2(- 2) + 2 = - 4 + 2 = - 2

solution is x = - 2, y = - 2

Answer:

The cost of homes per square foot differs in different part of the United states. The cost of homes per square foot is gotten by using the formula:

cost of homes per square foot = Cost of apartment / area of apartment

1) Cost of apartment = $540000, area of apartment = 450 ft²

cost of homes per square foot = Cost of apartment / area of apartment = $540000/ 450 ft² = $1200 / ft²

2) cost of homes per square foot = $110/ ft²,  area of apartment = 2100 ft²

cost of homes per square foot = Cost of apartment / area of apartment

$110 / ft² = Cost of apartment / 2100 ft²

Cost of apartment = $110 / ft² × 2100 ft² = $231000

Answer:

The weight of the wood before he chopped it is 245 N

Step-by-step explanation:

The law of conservation of mass states that for a given isolated system, mass (or matter) can not be created neither can it be destroyed, but it can be transformed into different forms

Therefore, whereby all the wood Chuck chops is taken as firewood, (wood which is dry is about 100% consumable as firewood) the mass of the wool before he chopped the wood = The mass of the firewood he had after chopping the wood = 25 kg

Weight = Mass × The acceleration due to gravity, g

g = Constant = 9.8 m/s²

The weight of the wood before he chopped it = 25 kg × 98 m/s² = 245 N.

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, and it needs additional information before it can be answered.

However, a possible question could be that we generate an equation that has 3 variables and equals 180.

A possible question is:

The sum of three consecutive numbers is 180. What is the highest number?

And the solution is as follows:

Let the three numbers (in order of smallest to greatest) be x, y and z

So, the sum is:

[tex]x + y + z = 180[/tex]

Since the numbers are consecutive, then the following relationship exist:

[tex]y = x + 1[/tex]

[tex]x = x + 2[/tex]

Substitute x + 1 for y and x + 2 for z in [tex]x + y + z = 180[/tex]

[tex]x + x + 1 + x + 2 = 180[/tex]

Collect Like Terms

[tex]x + x + x = 180 - 3[/tex]

[tex]3x = 177[/tex]

Solve for x

[tex]x = 177/3[/tex]

[tex]x = 59[/tex]

The value of the highest being is:

[tex]z = x + 2[/tex]

[tex]z = 59 + 2[/tex]

[tex]z = 61[/tex]

You can generate as many equation as possible

Answer:7/3

Step-by-step explanation:

i went on a website and got the answer

Answer:

[tex]DG = 26[/tex]

[tex]GE = 26[/tex]

[tex]DF = 15[/tex]

[tex]CH = 14[/tex]

[tex]CE = 28[/tex]

Step-by-step explanation:

The figure has been attached, to complement the question.

[tex]DE = 52[/tex]

[tex]FC = 15[/tex]

[tex]HE = 14[/tex]

Given that J is the centroid, it means that J divides sides CD, DE and CE into two equal parts respectively and as such the following relationship exist:

[tex]DF = FC[/tex]

[tex]CH = HE[/tex]

[tex]DG = GE[/tex]

Solving (a): DG

If [tex]DG = GE[/tex], then

[tex]DE = DG + GE[/tex]

[tex]DE = DG + DG[/tex]

[tex]DE = 2DG[/tex]

Make DG the subject

[tex]DG = \frac{1}{2}DE[/tex]

Substitute 52 for DE

[tex]DG = \frac{1}{2} * 52[/tex]

[tex]DG = 26[/tex]

Solving (b): GE

If [tex]DG = GE[/tex], then

[tex]GE = DG[/tex]

[tex]GE = 26[/tex]

Solving (c): DF

[tex]DF = FC[/tex]

So:

[tex]DF = 15[/tex]

Solving (d): CH

[tex]CH = HE[/tex]

[tex]CH = 14[/tex]

Solving (e): CE

If [tex]CH = HE[/tex], then

[tex]CE = CH + HE[/tex]

[tex]CE = 14 + 14[/tex]

[tex]CE = 28[/tex]

Answer:

angle c is 40° where angle d is75°

Given:

Sarah ate [tex]\dfrac{1}{5}[/tex] of the pizza.

Her friend John ate 20%.

Her friend Jules ate half of the pizza.

To find:

The remaining part of the pizza.

Solution:

We have,

Sarah ate = [tex]\dfrac{1}{5}[/tex] of the pizza.

John ate = [tex]20\%[/tex]  of the pizza.

              = [tex]\dfrac{20}{100}[/tex]  of the pizza.

              = [tex]\dfrac{1}{5}[/tex] of the pizza.

Jules ate = [tex]\dfrac{1}{2}[/tex] of the pizza.

Total part of a pizza they ate = [tex]\dfrac{1}{5}+\dfrac{1}{5}+\dfrac{1}{2}[/tex]

                                 = [tex]\dfrac{2+2+5}{10}[/tex]

                                 = [tex]\dfrac{9}{10}[/tex] of the pizza.

Now, the remaining pizza is

Remaining pizza = 1 - Total part of a pizza they ate

                            = [tex]1-\dfrac{9}{10}[/tex] of the pizza.

                            = [tex]\dfrac{10-9}{10}[/tex] of the pizza.

                            = [tex]\dfrac{1}{10}[/tex] of the pizza.

Therefore, the remaining pizza is [tex]\dfrac{1}{10}[/tex] of the pizza.

Answer:

see explanation

Step-by-step explanation:

The explicit formula for a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 200 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{100}{200}[/tex] = [tex]\frac{1}{2}[/tex] , then

[tex]a_{n}[/tex] = 200 [tex](\frac{1}{2}) ^{n-1}[/tex] ← explicit formula

The 15 th term is then

a₁₅ = 200 × [tex](\frac{1}{2}) ^{14}[/tex]

     = 200 × [tex]\frac{1}{16384}[/tex]

     = [tex]\frac{200}{16384}[/tex] ← divide numerator/ denominator by 8

     = [tex]\frac{25}{2048}[/tex]
