Answer:

The area of the blank M is 326.56m²

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes

Given data

Diameter of flower bed d=22m

Radius of flower bed r= 11m

Width of side walk x =4m

To solve for the area of the blank we need to subtract the area of the side walk from the area of the flower bed

But we don't know the diameter of the side walk

Let the diameter of the side walk be D= diameter of flower bed +2(width of the side walk )

D= 22+2(4)

D=22+8

D=30m

Radius of side walk is R=30/2 =15m

Area of blank =area of side walk minus area of flower bed

Area of circle =πr²

Area of blank M = πR²-πr²

M= π(R²-r²)

M= 3.14(15²-11²

M=3.14(225-121)

M=3.14(104)

M= 326.56m²

The area of the blank M 326.56m²

M to the power of 2 =326.56²=106641.43

Answer: 3. d= -4    , 4. m= -3  , 5. w= 82 , 6. x=42 , 7. x=24 , 8. x= -60

Step-by-step explanation:

3. Step 1: Add 6 to both sides.

d−6+6=−10+6

d=−4

4. Step 1: Add 14 to both sides.

m−14+14=−17+14

m=−3

5. Step 1: Add 23 to both sides.

w-23+23=59 + 23

w= 82

Continue to repeat the step for the other ones. If there is a positive then subtract on both sides!

Step-by-step explanation:

Multiply the altitude of the diamond times the length of one of its sides. The altitude is the distance between any two opposite sides of the diamond. So if the diamond has an altitude of 2 feet and its sides are each 3 feet long, its area is 2 * 3 = 6 feet squared.

Answer:  

1A. = 68.96 degrees.

2A.  = YES

Step-by-step explanation:

Hi, to answer this question we have to apply:

sin (angle ) = opposite side / hypotenuse

Since the triangle formed is a right triangle ( see attachment), the hypotenuse is the length of the ladder (the longest side), and the opposite side to the angle is the distance between the top of ladder and the ground.

Replacing with the value given

sin x = 14/15

Solving for x

x = arcsin 14/15

x = 68.96 degrees. (1A)

Since the angle is lower than 75 degrees, the ladder is safe the way is positioned.

Answer:

[tex] - 3x + 10 = - 20 \\ - 3x = - 20 - 10 \\ - 3x = - 30 \\ \frac{ - 3x}{ - 3} = \frac{ - 30}{ - 3} \\ x = 10[/tex]

Steps to solve:

-3x + 10 = -20

~Subtract 10 to both sides

-3x + 10 - 10 = -20 - 10

~Simplify

-3x = -30

~Divide -3 to both sides

-3x/-3 = -30/-3

~Simplify

x = 10

To find Ben's age, we establish an equation based on the given information that Ben is three times as old as Daniel and four years older. Solving this equation reveals that Daniel is 2 years old, therefore, Ben is 6 years old.

The question states that Ben is 3 times as old as Daniel and also 4 years older than Daniel. To solve for Ben's age, let's assign the variable D to represent Daniel's age. Therefore, Ben's age can be expressed as 3D. It's also stated that Ben is 4 years older than Daniel, which gives us another equation, Ben's age equals Daniel's age plus 4 (D + 4).

Setting these two expressions for Ben's age equal to each other gives us: 3D = D + 4. By solving this equation, we subtract D from both sides to get 2D = 4. Dividing both sides by 2 gives us D = 2, which is Daniel’s age.

To find Ben's age, we multiply Daniel’s age by 3, as Ben is three times older than Daniel. So, Ben's age is 3 * 2 = 6 years old.

The value -3/7 falls into the category of Rational Numbers. This category includes all numbers that can be expressed as a fraction or quotient of two integers.

The value -3/7 belongs in the group of Rational Numbers. Rational numbers are defined as any number that can be represented as the quotient or fraction p/q of two integers, with the denominator q not equal to zero. Integers and Natural numbers, option A and B, do not include negative values or fractions. An irrational number, option D, cannot be written as a simple fraction. Since -3/7 is a negative fraction, it can only be classified as a rational number. So, -3/7 would be placed in the section representing Rational Numbers on a Venn diagram of number types.

Answer:

(6, 9 )

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), thus

(- 6, 9 ) → (6, 9 )

Reflection over the y-axis in mathematics changes the sign of the x-coordinate of a point while the y-coordinate remains unchanged. Therefore, the point (-6,9) reflects over the y-axis to become (6,9).

In mathematics, a reflection over the y-axis is a geometrical transformation of a point in a two-dimensional space. When we reflect a point over the y-axis, the x-coordinate of that point changes its sign, while the y-coordinate remains the same.

Given the point (-6,9), after reflection over the y-axis, it will become (6,9). This is because the reflection changes the sign of the x-coordinate, turning -6 into 6, while the y-coordinate remains the same.

Answer:

x² - 10x + 25

Step-by-step explanation:

Given

(x - 5)²

= (x - 5)(x - 5)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 5) - 5(x - 5) ← distribute both parenthesis

= x² - 5x - 5x + 25 ← collect like terms

= x² - 10x + 25

Answer:

C

Step-by-step explanation:

Given f(x) then f(x + h) represents a horizontal translation of f(x)

• If h > 0 then a shift to the left of h units

• If h < 0 then a shift to the right of h units

Here the shift is 5 units right, thus g(x) = (x - 5)²

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here the shift is 3 units down, thus g(x) = f(x) - 3

Hence

g(x) = (x - 5)² - 3 → C

From the given data sets, only option A has more than one mode (30 and 50),

so the correct answer is:

A. {10, 20, 30, 30, 40, 50, 50}.

We know that, A mode is a value in a dataset that appears most frequently.

To determine which data set has more than one mode, we need to find the sets that have multiple values that appear most frequently.

Let's examine each data set:

A. {10, 20, 30, 30, 40, 50, 50}

Mode(s): 30 and 50 (both appear twice)

B. {10, 20, 30, 40, 50, 70, 70}

Mode(s): 70 (appears twice)

C. {20, 20, 30, 30, 30, 40, 40}

Mode(s): 30 (appears three times)

D. {10, 20, 30, 40, 50, 60, 70}

Mode(s): None (each value appears only once)

From the given data sets, only option A has more than one mode (30 and 50),

so the correct answer is:

A. {10, 20, 30, 30, 40, 50, 50}.
