This is a gardener's floor plan of their backyard. Enter the amount of grass, in square yards
needed to completely cover the backyard.

Answers

Answer 1

Step-by-step explanation:

that is a tiny, tiny backyard ...

what I see immediately is that the area is a combination of multiple simple figures :

1 square on top,

1 smaller rectangle in the middle,

1 larger rectangle at the bottom.

we only need to calculate the areas of all 3 figures and then add then up for the total.

that's it.

the top square is easy :

it is a 3cm×3cm square, so the area is 9 cm²

the bottom rectangle is also easy :

it is a 10cm×3cm rectangle, so the area is 30 cm²

for the dimensions of the middle rectangle we need to think a little bit :

the width (or "height") is clear : 3 cm.

what is the length ?

the answer is given by some other pieces of information in the diagram. look closely : is the length of the middle rectangle not the same as the sum of the side length of the top square (3 cm) and the top side segment left of the top square : 2 cm ?

yes, it is, so the length is 3+2 = 5 cm.

and the middle rectangle is 5×3 = 15 cm².

so, the total area is

9 + 30 + 15 = 54 cm²

this is a backyard for Barbie and Ken ...

Answer 2

Amount of grass in the backyard is 0.641 square yards

What is a square?

Any 2-dimensional figure bounded by 4 sides whose all sides are equal and all the angles are 90° is called a square.

How to find the area of a square?

Area of a square can be found by squaring the length of one of its sides.

What is a rectangle?

Any 2-dimensional figure bounded by 4 sides whose opposites sides are equal and parallel and all the angles are 90° is called a rectangle.

How to find out area of a rectangle?

Area of a rectangle can be found by multiplying its length by its breadth.

How to calculate the area in the given problem?

The given figure is a combination of multiple figures.

1 square of length 3 cm on top1 rectangle in the middle whose length is ( 2 + 3) cm = 5 cm, and breadth is 3 cm1 larger rectangle at the bottom whose length is 10 cm and breadth is 3 cm.We will have to calculate these areas and sum up the areas to get the entire area.Area of the square at the top = ( 3 x 3) cm² = 9 cm²Area of the middle rectangle = ( 5 x 3) cm² = 15 cm²Area of the bottom rectangle = (10 x 3) cm² = 30 cm²

∴ Total area of the backyard = ( 9 + 15 + 30) cm² = 54 cm²

Amount of grass in the backyard = (54 x 0.109² ) square yards

= 0.641 square yards ( 1 cm = 0.109 yards)

Answers

Answer:

2048 or D

Step-by-step explanation:

We can use the formula c=(pi)(d)

replace 6,430.72 with c!

c=(pi)(d)

6,430.72=3.14*d

- Divide both sides by 3.14 -

How to determine the greatest fraction?

Fractions are numbers that are represented by the quotients of two integers.

The fractions are given as:

1/6, 5/6, -1/6 and -5/6

Negative numbers are less than positive numbers.

So, the remaining fractions are:

1/6 and 5/6

Both fractions have the same denominator.

So, we consider the numerator

5 is greater than 1

Hence, the fraction with the greatest value is 5/6

Find the sum of the first 21 terms of the arithmetic series.
46 +53 +60 +67+ ...

Answers

Answer:

2436

Step-by-step explanation:

The sum of n terms of an arithmetic series is given by the formula ...

Sn = (n/2)(2a +d(n -1))

where a is the first term, and d is the common difference.

This series has ...

a = 46

d = 53 -46 = 7

n = 21

So, the desired sum is ...

S21 = (21/2)(2(46) +7(20)) = 2436

The sum of the first 21 terms is 2436.

the answer is 153.86 ft squared

= the formula for the area of a circle is A=πr2

= multiply 49 by pi to get the area: 153.86 square feet

153.86 ft squared

Answer:

153.86 ft squared

Step-by-step explanation:

As per given question we have provided that :

➟ Radius of circular pool = 7 feet

We need to find :

➟ Area of circular pool

Here's the required formula :

[tex]{\dashrightarrow\sf{A = \pi {r}^{2}}}[/tex]

↝ A = Area ↝ π = 3.14 ↝ r = radius

Substituting all the given values in the formula to find the area of circular pool :

[tex]{\dashrightarrow{\sf{Area = \pi {r}^{2}}}}[/tex]

[tex]{\dashrightarrow{\sf{Area = 3.14{(7)}^{2}}}}[/tex]

[tex]{\dashrightarrow{\sf{Area = 3.14{(7 \times 7)}}}}[/tex]

[tex]{\dashrightarrow{\sf{Area = 3.14{(49)}}}}[/tex]

[tex]{\dashrightarrow{\sf{Area = 3.14 \times 49}}}[/tex]

[tex]{\dashrightarrow{\sf{Area = 153.86}}}[/tex]

[tex]\star{\underline{\boxed{\sf{\red{Area = 153.86 \: {ft}^{2}}}}}}[/tex]

Hence, the area of circular pool is 153.86 ft².

What is a z-score?

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The weights of four years old boys are normally distributed with a mean of 38 pounds and a standard deviation of 4 pounds.

The value of the z-score at 90% will be 1.645

Then the weights that represent the 90% of the weight of a four year old will be

1.645 = (x - 38)/4

6.58 = x - 38

x = 44.58
