Answer:

10cm

Step-by-step explanation:

If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:

A = (1/2) * b * h

where A is the area, b is the base, and h is the height. Don't ask me why, it just works.

Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.

Then we put these numbers into the magic spell and we get:

50 = (1/2) * 10 * h

Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:

- Multiply both sides by 2. This gives us:

100 = 10 * h

- Divide both sides by 10. This gives us:

10 = h

- Celebrate! We found the height!

So, one of the heights of the triangle is 10 cm. Isn't math fun?

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Step-by-step explanation:

2 2/3 ÷ 2/3

2 2/3 = \(\frac{3}{3}\) + \(\frac{3}{3}\) + \(\frac{2}{3}\) = \(\frac{8}{3}\)  (\(\frac{3}{3}\) is another name for 1)

\(\frac{8}{3}\) ÷ \(\frac{2}{3}\) = \(\frac{4}{1}\) = 4

Answer: y = 63.20x + 22.25, where x is the number of months and y is the total cost.

Step-by-step explanation:

Let's start by finding the value of the constant term c. We know that the first month of service costs $85.45, so we have:

y = c + d(x – 1)

85.45 = c + d(1 – 1)

85.45 = c

Now we need to find the value of the slope d. We can use the information from the second and third months:

y = c + d(x – 1)

148.65 = 85.45 + d(2 – 1)

63.20 = d

y = c + d(x – 1)

211.85 = 85.45 + d(3 – 1)

126.40 = 2d

Simplifying the second equation, we get:

63.20 = d

Substituting the values of c and d into the equation, we get:

y = 85.45 + 63.20(x – 1)

y = 63.20x + 22.25

Therefore, the equation that represents this situation is:

y = 63.20x + 22.25, where x is the number of months and y is the total cost.

Step-by-step explanation:

The equations y + 1 = 5( x−9 ) , 7y + 2x = 12 and 4y = 24 are linear equations whereas 72 = x³ + y is a non linear equation

What are Linear Equations?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution

On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.

Given data ,

a)

Let the equation be 72 = x³ + y

Now , we can see that the power of x is of the order 3 , and therefore on the graph it forms a non linear shape

Therefore , it is a non linear equation

b)

Let the equation be y + 1 = 5( x−9 )

Now , this is a linear equation in two variables in the form of ax + by + c =0

Therefore , this is a linear equation

c)

Let the equation be 7y + 2x = 12

Now , this is a linear equation in two variables in the form of ax + by + c =0

Therefore , this is a linear equation

d)

Let the equation be 4y = 24

Now , The linear equations in one variable is an equation which is expressed in the form of ax+b = 0

Therefore , this is a linear equation

Hence , the equations y + 1 = 5( x−9 ) , 7y + 2x = 12 and 4y = 24 are linear equations whereas 72 = x³ + y is a non linear equation

Answer:

351.68 cm^2

Step-by-step explanation:

We need to find the area of the frame itself. the radius of the inner circle is 12, but the frame has a radius of 4. You add 12 and 4 and you get 16. The formula for area of a circle is A=πr^2. So A= 3.14 x16^2. Then you have A= 3.14x 256 and you get 803.84. But we only want the area of the frame, so you have to get the area of the inner circle and subtract. You get A= 3.14 x 12^2. 3.14x144 is 452.16. 803.84-452.16 is 351.68. Hope this helped. :)

Answer:

351.86cm²

Step-by-step explanation:

12+4=16

(total radius of the whole circle)

use the formula a= πr² to find area

area of the full circle = π*16² (256 π)

256π - area of the smaller circle

256π -  π*12²

256 π - 144 π = 112πcm² or 351.86cm² (to 2dp)
