Jane needs to buy mulch to cover a circular garden

Mathematics
1 answer:
scoray [572]2 years ago

Answer:

$3089.4

Step-by-step explanation:

A circle is a locus of a point such that its distance from a point known as the center is always constant.

The area of a circle is given by the formula:

Area = πr²; where r is the radius of the circle.

From the image attached, we can see that the garden is circular with a radius of 5.5 yard. Hence:

Amount of mulch needed to cover garden = area of garden = πr² = π(5.5)²  = 95 yd²

Since mulch cost $32.52 per square yard, hence:

Cost of mulch needed = $32.52 per yd² * 95 yd² = $3089.4

A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &730\\
r=rate\to 27.6\%\to \frac{27.6}{100}\to &0.276\\

The price of 600 grams of candy and 1.5 kg of cookies was 4 dollars and 62 cents. What is the price of one kg of cookies if it i
cupoosta [38]

Answer:

The price of the kilogram of cookies is $ 1.8

Step-by-step explanation:

Call x the price of the kilogram of candy and call y the price of kilogram of cookies

Then we know that

0.600x + 1.5y = 4.62

We also know that the price of kilogram of cookies is 1.40 dollars cheaper than the kilogram of candy

So

y = x-1.40

We solve this equation for x and then we substitute it in the first equation.

x = y + 1.40

0.60 (y +1.40) + 1.5y = 4.62\\\\0.60y + 1.5y = 4.62 - 0.84\\\\2.1y = 3.78

y = \$1.8
