Answer:

the area of grass is 314 square feet

Step-by-step explanation:

The radius of the circle the goat can reach is given by the length of the rope that ties the goat to the post (10 ft)

Then the area of the circle is: [tex]Area=\pi\,R^2=3.14\,(10\,\,ft)^2=3.14 * (100)\,ft^2=314 \,\,ft^2[/tex]

So the area of grass is 314 square feet

Answer:

fraction of the wall is limestone is 4/22

or 2/11 as a reduced fraction

Step-by-step explanation:

fraction of the wall is limestone is 4/22

the width is 22 in total

10 inches concrete = 10/22

8 inches brick : 8/22

4 inches limestone : 4/22

10/22+8/22+4/22=22/22=1

Answer:

P(x)=3x-150

Step-by-step explanation:

It is given that,

Daily revenue, R(x) = 5x, x is the number of customers that visit the gym each day

The daily cost pf the gym, C(x) = 2x+150

We need to find the profit function. It is given by :

P(x) = R(x) - C(x)

P(x) = 5x-(2x+150)

P(x) = 5x-2x-150

P(x)=3x-150

So, the correct option is (c) "P(x)=3x-150".

Answer:

The product is usually smaller than the two numbers multiplied

Step-by-step explanation:

When we multiply two decimals less than one, it is a certainty that the result of the multiplication would be less than the two decimals that were multiplied. An example is the multiplication of the decimals below;

0.958 * 0.325

which equals 0.31135

We can see from the example above that the result of the multiplication of the two decimals that are less than one, results in a product that is less than the factors that were multiplied.

Answer:

D. 82 square units

Step-by-step explanation:

The area of the given rectangle is 82 square units. The correct option is (D).

The distance formula is used to find the distance between two points (x₁, y₁) and (x₂, y₂) as √((x₁ - x₂)^2 + (y₁ - y₂)^2).

By knowing the sides, the area of different polygonals such as parallelogram, trapezium and rectangles etc. canbe found.

The vertices of the rectangle are given as (9, – 1), (-1, 7), (-5, 2), (5, 6).

Suppose A, B, C and D are the corresponding vertices.

In order to find the area length and breadth is required.

Here, AB is the length and BC is the breadth which can be found using the distance formula as,

AB = √((-1 - 9)^2 + (7- (-1))^2)

     = √(10² + 8²)

     = 12.8

BC = √((-5 - (-1))^2 + (2 - 7)^2)

     =√(-4² + -5²)

     = 6.4

Thus, Area = AB ×  BC

                  = 12.8 × 6.4

                  = 81.92

Which is approximately 82.

Hence, the area of the rectangle is 82 square units approximately.

Answer:

[See Below]

Step-by-step explanation:

Rewrite:

* |2 + 3 x -4|

Solve:

* 2 + 3 = 5

* 5 x -4 = -20

Now solve using absolute value:

* -20 = 20

(With absolute value it's just a short way of saying no negatives or fractions. It'd be the whole number of the number. Another example of this would be 8/1; the absolute value would be 8.)

Answer:

y = 4

Step-by-step explanation:

If two triangles are similar then,

i)  Corresponding angles will be equal

ii) Corresponding sides will be in the same ratio.

[tex]\frac{AC}{EF}=\frac{CB}{FD}\\\\\\\frac{12}{y}=\frac{15}{5}\\\\[/tex]

Cross multiply,

12*5 = y*15

y*15 = 12*5

[tex]y=\frac{12*5}{15}\\[/tex]

y = 4

Answer:

∠DEF = 60

x = 11.4

y = 4

Step-by-step explanation:

Step 1: State what is known

The question tells us that Triangle ABC is similar to Triangle EFD, We know similar angles share the same angles and the sides are similar to the corresponding side

Step 2: Find the unknown angle

Because we know the triangles are similar we need to find ∠BAC to solve for 'z'

z = 180 - 55 - 65

z = 60

Step 3: Find the unknown side with the ratio

We know 1 pair of sides BC and DF and it gives us a ratio of BC : DF or 3 : 1

We can set the ratios equal to an unknown side to solve:

3 : 1 = 12 : y

We can multiple 3 : 1 by 4 to get the 'y'

12 : 4

y = 4

3 : 1 = x : 3.8

We can multiple 3 : 1 by 3.8 to get 'x'

11.4 : 3.8

x = 11.4

Therefore ∠DEF = 60, side x = 11.4 and side y = 4

Step-by-step explanation:

Answer:

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

[tex]\frac{y-1}{2}[/tex] = x

Change y back into terms of x

Answer:

Strips should be 1.5 ft wide.

Step-by-step explanation:

Given:

Width of 1st piece = 6 ft

Width of 2nd piece = 7.5 ft

To find:

To find the maximum width possible to make strips of equal size from both the pieces.

Solution:

This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.

Let us try to factorize the given factors:

[tex]7.5 = 3 \times 2.5 = \underline {3 \times 0.5} \times 5[/tex]

[tex]6 = 3 \times 2 = \underline {3 \times 0.5 }\times 2[/tex]

The common factors are highlighted above as underlined.

Therefore, the answer is 3 [tex]\times[/tex] 0.5 = 1.5 ft

Strips should be 1.5 ft wide.

Answer:

49, 35, and 32

Step-by-step explanation:

A composite number is one that may be generated by multiplying two smaller positive numbers. The correct options are A, B, and C.

A composite number is one that may be generated by multiplying two smaller positive numbers. It is a positive integer with at least one divisor other than 1 and itself.

Composite numbers are those numbers that are divisible by other numbers and form 1 and itself as well.

49

49 is divisible by 7, therefore, it is a composite number.

35

35 is divisible by 7, therefore, it is a composite number.

32

32 is divisible by 2, therefore, it is a composite number.

41

Since 41 is not divisible by any other number except 1 and itself, therefore it is not a composite number.

47

Since 47 is not divisible by any other number except 1 and itself, therefore it is not a composite numbers.

Hence, the correct options are A, B, and C.
