Suppose P, Q, and R are points in the plane such that PQ=1.8, PR=8.2, and angle PQR=90 degrees. What is the area of triangle PQR$?

Answers

Answer 1

Answer:

7.2 sq units

Step-by-step explanation:

Seeing as this is a right triangle, and the hypotenuse and one leg is given, you can use the pythagorean formula to get the third side ([tex]\sqrt{8.2^2 - 1.8^2}[/tex]). Now that we have this leg, we can multiply this by 1.8, then divide it by two (area of triangle).

To find the equation, you have to know the slope (5x) and the y intercept (25)
(Formula: y=mx+b) It says the input= x.
So plug 200 for x
5(200)+25=1025

The value of output for value of input of 200 is,

⇒ y = 1025

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The table shows the outputs for several inputs.

Now, We can find the expression for the table as;

Take two points are (0, 25) and (1, 30)

Hence, The equation is,

y - 25 = (30 - 25) / (1 - 0) (x - 0)

y - 25 = 5x

y = 5x + 25

Hence, The value of output for value of input of 200 is,

y = 5 × 200 + 25

y = 1000 + 25

y = 1025

Thus, The value of output for value of input of 200 is,

⇒ y = 1025

Answers

Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Answer:

r = 5.8 meters

Step-by-step explanation:

The volume formula is V = (4/3)(pi)(r^3), where r is the radius.

Solving for r, we get first 3V = (4pi)(r^3), so that r^3 = (3V)/(4pi)

or in this case, r^3 = 3(802 m^3) / (4pi) = 191.5 meters^3

Taking the cube root of both sides yields r = 5.8 meters

Answer:

-0.58

Step-by-step explanation:

The number gets less as you move to the bottom. Each dash represents 0.01. The dot is 3 lines below -0.55, so you would do -0.55 - 0.03, and the answer is -0.58.

I hope this helps and please mark me as brainliest!

Answer:

-0,56

Step-by-step explanation:

As you go up, the numbers tend to get larger. -0.5 is larger than - 0.6

So considering where the dot is on the number line, you have to subtract - 0.02 for every horizontal line you cross.

Another way of putting this is you must add 0.02.

For me, it is easier to add 0.02 because the amount is getting bigger. Why 0.02? it is because there are 5 horizontal notches between -0.6 and - 0.5. Each notch must be -.1/5 = -0.02

First notch: -0.6 + 0.02 = -0.58

Answer: Second notch: -0.58 + 0.02 = -0,56

1. 6 feet long
2. The border increases the length of each side by 1 foot
3. The width of the border is 6 inches (0.5 feet) because it adds on 1 foot in length to each side. Splitting it between the 2 borders for each side would make it 6 inches.

Answer:

1.  6 ft

2. 1 ft

3. 1/2 ft

Step-by-step explanation:

We know that the quilt is the shape of a square, since we are told that the main design has the same length sides of 5 ft.

Area of a square = s² (where s is the side length)

If the finished quilt has an area of 36 ft² then the length of one side is:

⇒ s = √(36) = 6 ft

Side length of main design = 5 ft

Side length of finished quilt = 6 ft

6 - 5 = 1 ft

Therefore, the border increased the total length of each side by 1 ft

As the border goes around the whole quilt, this means that the extra 1 ft needs to be divided by 2, so that each side has an equal amount added.

Therefore, the width of the border is 1/2 ft

**see attached diagram.  Main design is shown in blue, border is shown in green**

Sum of interior angles of a triangle = 180 degrees.
So, 180 - (40 + 70) = 180 - 110

So, angle next to 70= 180 - 70 = 110 degrees.
