Answer:

  $12.07

Step-by-step explanation:

The cost is proportional to the weight, so we have ...

  dollars/pounds = c/4.2 = 8.62/3

Multiplying by 4.2 gives ...

  c = 4.2×8.62/3 = 12.068

The cost of 4.2 pounds of strawberries is $12.07.

Answer:

y = 240,000(1.048)^t

Step-by-step explanation:

Initial population: p = 240,000

Annual growth rate: 4.8% = 0.048

Number of years: t

Population in year t: y

y = p(1 + r)^t

y = 240,000(1 + 0.048)^t

y = 240,000(1.048)^t

Answer:

The equivalent functions are;

[tex]g(x) = 3^{-2 \cdot x }[/tex]

[tex]g(x) = 9^{-x}[/tex]

[tex]g(x) = \left (\dfrac{1}{9} \right )^x[/tex]

Step-by-step explanation:

The given function is f(x) = (1/3)^(2·x)

[tex]f(x) = \dfrac{1}{3} ^{2 \cdot x}[/tex]

The given  function can be simplified as follows;

[tex]f(x) = \dfrac{1}{3} ^{2 \cdot x} = 3^{-1 \cdot2 \cdot x } = 3^{-2 \cdot x } = g(x)[/tex]

∴ [tex]f(x) = \dfrac{1}{3} ^{2 \cdot x}[/tex] ≡  [tex]g(x) = 3^{-2 \cdot x }[/tex]

2) The given  function can also be simplified as follows;

[tex]f(x) = \dfrac{1}{3} ^{2 \cdot x} = \left (\dfrac{1}{3} ^2\right )^x = \left (\dfrac{1}{9} \right )^x = (9^{-1}) ^x} = 9^{-1 \times x} = 9^{-x} = g(x)[/tex]

∴ [tex]f(x) = \dfrac{1}{3} ^{2 \cdot x}[/tex] ≡ [tex]g(x) = 9^{-x}[/tex]

3) The given  function can also be simplified as follows;

[tex]f(x) = \dfrac{1}{3} ^{2 \cdot x} = \left (\dfrac{1}{3} ^2\right )^x = \left (\dfrac{1}{9} \right )^x = g(x)[/tex]

∴ [tex]f(x) = \dfrac{1}{3} ^{2 \cdot x}[/tex] ≡ [tex]g(x) = \left (\dfrac{1}{9} \right )^x[/tex]

"A number" means the unknown.

"Difference" means to subtract.

We already know two numbers, 8 and 14, but we don't know "A number."

We can put v as our variable. You can put any type of letter.

Therefore, the answer is: v - 8 = 14

Answer:

$360

Step-by-step explanation:

You have to calculate the interest earned on $3,000, at the rate of 0.04 for 3 years.

P= $ 3000, R= 0.04 and t= 3 years.

3000 × 0.04 × 3= $360 (Answer)

Hope that helps

Have a good day :)

Answer:

$360.

Step-by-step explanation:

The interest earned on principal P, at the rate of r for the duration of t years is given by the equation I = Prt ........... (1)

Now, we have to calculate the interest earned on $3000, at the rate of 0.04 for 3 years.

Here, P = $3000, r = 0.04 and t = 3 years.

Hence, from equation (1), Interest earned, I = 3000 × 0.04 × 3 = $360 (Answer)

Based on the question, each person will have 2/3 of the item

From the given information, we are told that 2 items are being divided equally among 3 people. This can be expressed as:

For each person;

x = 1 person

Take the ratio to have:

2/x = 3/1

3x = 2

x = 2/3

This shows that each person will have 2/3 of the item

Answer:

Looks like true to me

Step-by-step explanation:

y = x +6

Answer: x = 5

Step-by-step explanation:

The area of a rectangle is the length times the width. Since the dimensions are given as functions of x, youre going to have to use FOIL to combine them, then set that answer equal to the given value of 72.

l*w = (x+3)*(x+4) = x^2 + 7x +12 = 72

Subtract 72 on both sides. There is a reason why we'll do this instead of subtracting 12. The quadratic formula will help us to solve for x.

x^2 + 7x - 60 = 0

Apply the quadratic formula

[tex]\frac{-7 (+/-)\sqrt{7^2-(4)*(1)*(-60} }{2*1} =\frac{-7(+/-)17}{2}[/tex]

We cant have a negative x value because that would result in negative dimensions and a negative area, which is impossible in this context. So you want to add the 17 instead of subtracting it.

x = 5 and x = -12

An alternate way is just factoring the trinomial to:

(x+12)(x-5) = 0

CASH = 7284

Step-by-step explanation:

MATHEMATICS = 12345123678

CASH = ?

Find what number the letters represent:

M = 1

A = 2

T = 3

H = 4

E = 5

I = 6

C = 7

S = 8

Then, replace the numbers in the word CASH:

C = 7

A = 2

S = 8

H = 4

Therefore, the number is 7284.

Answer:

5.667 yards of fabric was used to make a cape

Step-by-step explanation:

(Total Yard of Fabric)1/3 = (What's Used)

Total Yard Fabric = 17

What's Used = x

1 third = 1/3

(17)1/3 = x

x = 17/3 or about 5.667 yards of fabric used

Double Check:

5.667/17 = 0.3334 which is about 1/3

If you want to find how much he has left:

1 - 1/3 = 2/3

17(2/3) = x

x = 34/3 or about 11.333 yards of fabric left.

Double Check:

11.333/17 = 0.6666 which is about 2/3
