Can you plz solve 6-8 on this pic you have to find the area for it plz

The pebbles cover an area of 147 sq ft. We can use the Pythagorean theorem to find the solution.

Let's call the length of the third side of the triangle "x".

Since the two triangles are equal in size, and they share two sides with the square, we can use the Pythagorean theorem to find x.

a² + b² = c²

7² + 7² = c²

49 + 49 = c²

98 = c²

c = sqrt(98)

c = 7sqrt(2)

So each triangle has a base of 7ft and a height of 7sqrt(2)ft.

Area of each triangle = (base * height) / 2 = (7 * 7sqrt(2)) / 2 = 24.5 sq ft

Since there are two triangles, the total area of the grass is 24.5 sq ft * 2 = 49 sq ft

The square has an area of 14ft * 14ft = 196 sq ft

The pebbles cover an area of 196 sq ft - 49 sq ft = 147 sq ft.

Answer:

the solution to the system of equations is (x, y) = (2, -2).

Step-by-step explanation:

The solution to the system of equations using the substitution method is as follows:

Starting with the equation y = x - 4, substitute this expression for y in the other equation:

-x + 6y = -14

-x + 6(x - 4) = -14

Expanding the expression in parentheses:

-x + 6x - 24 = -14

5x = 10

Dividing both sides by 5:

x = 2

Now that x is known, substitute x = 2 back into the first equation to solve for y:

y = x - 4

y = 2 - 4

y = -2

So the solution to the system of equations is (x, y) = (2, -2).

Answer:(2,-2)

Step-by-step explanation:

we can substitute (y) = x - 4 into -x + 6(y) = -14 's y

so -x + 6(x-4) = -14 distribute the 6

-x + 6x - 24 = -14 add 24 on both sides and subtract x with 6x

5x = 10 divide 5 to isolate x

x = 2 now we find the y value

y = x - 4 plug 2 in for x

y = 2 - 4 -> y = -2

(x,y) -> (2,-2)

A goniometer is a tool used to measure the range of motion of a joint. It helps determine the degrees of flexion and extension of the joint. By using this device, healthcare professionals can assess the mobility and flexibility of a joint.


A goniometer is a simple tool that consists of two arms and a protractor. It is used to measure the range of motion of a joint, such as the shoulder or knee. The arms of the goniometer are aligned with the bones on either side of the joint, and the protractor is used to measure the angle between the arms. This angle indicates the degrees of flexion and extension of the joint.

For example, if a physical therapist wants to assess a patient's knee mobility, they would place the goniometer on the patient's knee joint and measure the angle as the patient moves their leg. This measurement helps determine the extent of movement and any limitations or abnormalities in the joint.

The hole size required for the meter to be bolted to the switchboard is 1.7565 inches in diameter, expressed in decimal form.

To find the hole size for the meter to be bolted to the switchboard, you need to add the given diameter difference of 1.32 inches to the diameter of the meter studs. The meter studs are 0.4365 inches in diameter. So, the calculation is as follows:

Hole size = Meter stud diameter + Diameter difference
Hole size = 0.4365 inches + 1.32 inches

Based on the properties of the angles of a parallelogram, the value of each variable are:

Thus:

(b - 10) + (b + 10) = 180

b - 10 + b + 10 = 180

Add like terms

2b = 180

b = 90

d = b + 10 (opposite angles)

Plug in the value of b

d = 90 + 10

d = 100°

c = b - 10

Plug in the value of b

c = 90 - 10

c = 80°

Therefore, based on the properties of the angles of a parallelogram, the value of each variable are:

Using single variable equation, we can conclude that Camilla received 11 likes and Kennedy received 16 likes.

Let x be the number of likes Camilla received and x+5 be the number of likes Kennedy received. We can set up an equation to solve for x:

x + (x+5) = 27

Simplifying the equation:

2x + 5 = 27

Subtracting 5 from both sides:

2x = 22

Dividing both sides by 2:

x = 11

So Camilla received 11 likes and Kennedy received 11+5=16 likes.

Answer:

slope of perpendicular line = - \(\frac{2}{3}\)

Step-by-step explanation:

calculate the slope m of the given line using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (3, 3) ← 2 points on the line

m = \(\frac{3-0}{3-1}\) = \(\frac{3}{2}\)

given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{\frac{3}{2} }\) = - \(\frac{2}{3}\)

All of the following are measures of central tendency except the range.

The range is a measure of dispersion, representing the difference between the largest and smallest values in a dataset. It provides information about the spread or variability of the data but does not provide information about the central tendency.

On the other hand, measures of central tendency are statistical measures that aim to summarize the center or typical value of a dataset. They include the mode, median, and mean.

The mode represents the most frequently occurring value(s) in the dataset.

The median is the middle value when the data is arranged in ascending or descending order. It divides the dataset into two equal halves.

The mean is the arithmetic average of all the values in the dataset. It is calculated by summing all the values and dividing by the total number of values.

Therefore, option C, range, is not a measure of central tendency as it focuses on the spread or dispersion of the data rather than summarizing the central or typical value.

the probability of all three cubes landing on odd numbers given that the white cube landed on three is 1/24

Since the white cube landed on 3, we only need to consider the red and green cubes.

The probability of each cube landing on an odd number is 1/2, since there are 3 odd numbers out of 6 total on each cube.

The probability of both the red and green cubes landing on odd numbers is the product of their individual probabilities:

P(red and green both odd) = P(red odd) x P(green odd) = 1/2 x 1/2 = 1/4

Therefore, the probability of all three cubes landing on odd numbers given that the white cube landed on three is:

P(white=3 and red and green both odd) = P(red and green both odd | white=3) x P(white=3)

= (1/4) x (1/6) = 1/24

So the probability of all three cubes landing on odd numbers given that the white cube landed on three is 1/24

Step-by-step explanation:

Step 1: Expand the brackets

-7 + 12e + 9

Step 2: Collect like terms

12e + 2

Because the answer is not a or b the answer is 'None of the Above'

Hey there! I'm happy to help!

Let's use the distributive property to undo the parentheses. We multiply the number next to the parentheses by each number inside of the parentheses.

-7+3(-4e-3)

-7-12e-9

We combine like terms.

-16-12e

This means that Answer B is incorrect. Answer A could still be correct though as it could have equal value to -16-12e.

-4(3e+4)

We use distributive property.

-12e-16

We see that these have the same value, so the correct answer is A.
