A cereal box has a surface area of 280 square inches. What is the surface are of a similar box that is larger by a scale factor of 1.4 ?

Answer:

24 km is your answer

Step-by-step explanation:

Let x be the distance between the two ships.

Hypotenuse side = x km

Adjacent side = 13.5 km

Perpendicular side = 20 km

by using Pythagoras theorem:

x²= 13.5²+ 20²=582.25

x=√ 582.25

х =24.129857024 km

Therefore, the distance between two ships to the nearest tenth place is, 24.1 km

Let us say x is the amount of money Sky makes for babysitting 7 hours.

[tex]\frac{72}{4} =\frac{x}{7}[/tex]

[tex]\frac{72}{4} = 18[/tex]

[tex]18=\frac{x}{7}[/tex]

x=$126

Answer:

136.2

Step-by-step explanation:

Plugin x = 18 in the polynomial.

P(x) = 0.02x³ + 0.04x² + 0.3x + 1.2

P(18)= 0.02*(18)³ + 0.04*(18)² + 0.3*18 + 1.2

      = 0.02 * 5832  + 0.04*324 + 5.4 + 1.2

      = 116.64 + 12.96 + 5.4 + 1.2

      = 136.2

Answer:

18 inches

Step-by-step explanation:

1 ft = 12 in

6 ft = ? in

Set up an equation to convert 6 feet into inches

Variable x = number of inches

1 ft/12 in = 6ft/x in

Cross multiply (feel free to ignore units for now so it doesn't get in the way of your calculations)

1 × x = 12 × 6

1x = 72

x = 72 inches

6 feet = 72 inches so replace 6 feet with 72 inches

Now let's find 1/4 of 72 inches

Set up another equation to solve

Variable y = a fourth of seventy two inches

1/4 = y/72

Cross multiply

1 × 72 = 4 × y

72 = 4y

Divide both sides by 4 to isolate variable y

72 ÷ 4 = 4y ÷ 4

18 = 1y

18 = y

Answer:

x= 9.81... repeating

Step-by-step explanation:

Divide 44 to isolate x.

(44)x = 432

x= 432/44

x= 9.818

Or if you want a fraction,

x= 108/11

Answer:

9.81

Step-by-step explanation:

The decimal is repeating by the way.

Divide 432 by 44 to get 9.81 (a repeated decimal)

Answer:

Jose stretched the taffy the farthest and Maria stretched it the least

Step-by-step explanation:

Distance stretched by George = 3 feet

Distance stretched by Jose is [tex]1\dfrac{1}{3}[/tex] times as much as George so

[tex]3\times 1\dfrac{1}{3}=3\times\dfrac{4}{3}=4\ \text{feet}[/tex]

Distance stretched by Jose is [tex]4\ \text{feet}[/tex]

Maria streched the taffy [tex]\dfrac{2}{3}[/tex] times as George

[tex]3\times \dfrac{2}{3}=2\ \text{feet}[/tex]

Maria stretched the taffy by [tex]2\ \text{feet}[/tex]

Sally stretched it [tex]\dfrac{6}{6}[/tex] so [tex]1\ \text{feet}[/tex]

So, Jose stretched the taffy the farthest and Maria stretched it the least.

Step-by-step explanation:

when dividing numbers with exponents with the same base, subtract the exponents.

[tex]\frac{8^{7} }{8^{7} }[/tex]

7 - 7 = 0

[tex]\frac{8^{7} }{8^{7} }[/tex] = [tex]8^{0}[/tex]

anything to the power of 0 is 1

[tex]8^{0}[/tex]= 1

Answer:

1

Step-by-step explanation:

Any number divided by itself equals 1 with the exception of 0 since 0/0 is undefined.

8^7 is not equal to zero, so without doing any calculations or using any other rules, we know that

8^7/8^7 = 1

We can use the rule of exponents for dividing powers.

Rule:

[tex] \dfrac{a^m}{a^n} = a^{m - n} [/tex]

Here we have a = 8, m = 7, and n = 7.

Applying the rule, we get

[tex] \dfrac{8^7}{a^7} = 8^{7 - 7} = 8^0 [/tex]

Another rule of exponents:

[tex] a^0 = 1 [/tex]

We the zero power rule now:

[tex] 8^0 = 1 [/tex]

Therefore,

[tex] \dfrac{8^7}{a^7} = 1 [/tex]

Answer: 1

Answer:

1 1/4 is the answer

Step-by-step explanation:

Step-by-step explanation:

f[g(4)]

g(x) = 4x

g(4) = 4(4)

= 16

f(x) = x-5

f[g(4)] = f(16) = 16 - 5 = 11

So, f[g(4)] = 11

Total Depreciation: 60.24%

Total depreciation: $9,759.50

Car Value after 6 years: $6,440.50

The element is remaining 146.6 grams after 7 minutes, to the nearest 10th of a gram.

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Given:

An element with mass 630 grams decays by 18.8% per minute.

That means, 18.8% = 0.188

Here, we will use the exponential decay function.

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Here,

A₀ = 630 grams

r = 0.188

x = 7 minutes

Substituting the values to the formula,

A₇ = 630(1-0.188)⁷

A₇ = 630(0.812)⁷

A₇ = 630(0.23275134787)

A₇ = 146.633

A₇ = 146.6 grams.

Therefore, element is remaining 146.6 grams.
