A gardener uses 1/3 of a liter of water to water 2/7 of a garden.

Serjik [45]

the gardener would need (1 + 1/6) liters of water to water the whole garden.

<h3>How much water would the gardener need to water the whole garden?</h3>

Here we know that the gardener needs 1/3 of a liter of water to water 2/7 of a garden.

Then we have the relation:

1/3 L = 2/7 of a garden.

Now, we want to get a "1 garden" in the right side of the equation, then we can multiply both sides by (7/2), so we get:

(7/2)*(1/3) L = (7/2)*(2/7) of a garden

(7/6)L = 1 garden.

(1 + 1/6) L = 1 garden

This means that the gardener would need (1 + 1/6) liters of water to water the whole garden.

Write an inequality to represent the graph below.

Yanka [14]

Answer:

The answer to your question is letter C

Step-by-step explanation:

Process

1.- Find two points of the line

A ( 0, -3) B ( 2, 2)

2.- Find the slope of the line

$m = \frac{y2 - y1}{x2 - x1} = \frac{2 + 3}{2 - 0}$

$m = \frac{5}{2}$

3.- Find the equation of the line

y - y1 = m(x - x1)

y + 3 = 5/2(x - 0)

y + 3 = 5/2 x

y = 5/2 x - 3

4.- Convert the line to an inequality, we want the upper area so use ">"

y > 5/2 x - 3

Suppose a deposit of $ 2 , 000 in a savings account that paid an annual interest rate r (compounded yearly) is worth $ 2 , 209 a

arsen [322]

Answer:

5.1% (nearest tenth)

Step-by-step explanation:

<u>Annual Compound Interest Formula</u>

$\large \text{$ \sf A=P\left(1+r\right)^{t} $}$

where:

A = final amount
P = principal amount
r = interest rate (in decimal form)
t = time (in years)

Given:

A = $2,209
P = $2,000
t = 2 years

Substitute the given values into the formula and solve for r:

$\implies \sf 2209=2000\left(1+r\right)^{2}$

$\implies \sf \dfrac{2209}{2000}=(1+r)^2$

$\implies \sf 1.1045=(1+r)^2$

$\implies \sf \sqrt{1.1045}=1+r$

$\implies \sf r = \sqrt{1.1045}-1$

$\implies \sf r = 0.05095194942...$

$\implies \sf r = 5.095194942...\%$

Therefore, the annual interest rate is 5.1% (nearest tenth)
