Answer:67

Step-by-step explanation:

42+30+79+99+72+24+89+91+78+69=673

673÷10=67.3

You divide by ten because that is how many numbers there are

The answer is A, 67.
you have to add all numbers and when you add them you get 673, then, you have to divide 673 by 10 because there are 10 numbers in the data set. you are going to get 67.3 which rounded to the nearest whole number is 67.

Answers

Answer:

60.00 in^2

Step-by-step explanation:

First focus on the area ABOVE the dotted line.  The shape here is that of a trapezoid.  The two leg lengths are 12 in and 18 in (18 in is the diameter).  At the far right of this trapezoid we can picture a triangle of base 3 in, height h and hypotenuse 5 in.  Using the Pythagorean Theorem, we get h = 4 in.

This 4 in measurement is the width of the trapezoid.  Thus, we are now ready to apply the formula for the area of a trapezoid:  A = (average length of legs)*(width).

Here that area comes out to

       12 in + 18 in

A = --------------------- * 4 in = 15 in*4in = 60 in^2, or (to the nearest hundredth)

                 2                                           60.00 in^2

Answers

Answer:

(2,-4)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The radius is the distance between the center and the point on the circle.

Center: (1, −3); Point: (1, −1)

Distance formula: d =  square root of {(x2 - x1)^2 + (y2 - y1)^2}

The total area of the figure is 77 square centimeters. The overall height of the figure is 9 centimeters.

Drag the correct measurements to label the unknown lengths in the figure.

Answers

Answer:

5cm and 10 cm

Step-by-step explanation:

Since the overall height of the shape is 9 and the base of the triangle shaped piece is 6, the area of that piece is 6*9/2=27 units. Subtracting this from the total of 77, you know that the rectangle must have an area of 50 units. Out of the options that you have to drag, the only two that multiply together to be 50 units are 5 for the shorter side and 10 for the longer side. Hope this helps!

The  correct measurements to label the unknown lengths in the figure 5 cm and 10cm.

What is Area of Rectangle?

The area of Rectangle is length times of width.

The overall height of the shape is 9 cm

The base of the triangle shaped piece is 6

The area of triangle is 1/2×base×height

Area of that piece is 6×9/2=27 units.

Now let us subtract this from the total area

Total is 77 units

the rectangle must have an area of 50 units.

the only two that multiply together to be 50 units are 5 for the shorter side and 10 for the longer side.

Hence, the  correct measurements to label the unknown lengths in the figure 5 cm and 10cm.

Graph a line with a slope of 2/5 with a point of -2/4

Answers

Answer:

See photo

Step-by-step explanation:

To graph a straight line, you need two points, then connect them.

Your first point is given: (-2, 4)

To get the next point, use the slope.

The slope 2/5 is written rise / run.

Rise is the number of units going up, or down if it's a negative number.

Run is the number of units rightwards.

Take the first point (-2, 4), and add the rise to the y-value. Add the run to the x-value.

x = -2, run = 5

New x = 3

y = 4, rise = 2

New y = 6

New point: (3, 6)

Plot the two points on the grid, then connect the dots.

A rocket is launched from a tower. The height of the rocket, y in feet is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.

y=-16x^2+165x+78

Answers

Final answer:

To find the maximum height reached by the rocket, we need to find the vertex of the quadratic equation. The maximum height is approximately 270.6 feet.

Explanation:

To find the maximum height reached by the rocket, we need to find the vertex of the quadratic equation. The equation is in the form of y = ax^2 + bx + c, where a = -16, b = 165, and c = 78. The x-coordinate of the vertex is given by -b/2a, and the y-coordinate is the value of y when x is the x-coordinate of the vertex. Plugging in the values, we find that the maximum height reached by the rocket is approximately 270.6 feet.

What does y equal when x = -6 in 3x + y = 6

Step-by-step explanation:

Subtract 3x from each side

3x -3x+ y = 6-3x

y = 6-3x

Let x = -6

y = 6 -3(-6)

   =6+18

1. 3x + y = 6

2. 3(-6) + y = 6

3. -18 + y = 6

Find the perimeter of the parallelogram with these vertices.(-2,2) ,(-2,-2) ,(6,-1) ,(6,-5)

Answers

Hope this helps you :)

The perimeter of the parallelogram with these vertices.(-2,2) ,(-2,-2) ,(6,-1) ,(6,-5) is 26 units.

In this explanation, we will find the perimeter of a parallelogram using its vertices' coordinates. The perimeter is the total length of all sides of the parallelogram. To find it, we'll apply the distance formula from coordinate geometry.

A parallelogram is a four-sided polygon with opposite sides parallel and equal in length. To calculate its perimeter, we need to find the lengths of all four sides and then add them together.

Step 1: Find the length of side AB.

Using the distance formula, the length of AB is

= √((-2 - (-2))² + (2 - (-2))²)

= √(0² + 4²)

= √16

= 4 units.

Step 2: Find the length of side BC.

Again, applying the distance formula, the length of BC is

= √((-2 - 6)² + (-2 - (-1))²)

= √((-8)² + 1²)

= √(64 + 1)

= √65 units.

Step 3: Find the length of side CD.

By using the distance formula, the length of CD is

= √((6 - 6)² + (-1 - (-5))²)

= √(0² + 4²)

= √16

= 4 units.

Step 4: Find the length of side DA.

Once more, applying the distance formula, the length of DA is

= √((6 - (-2))² + (-5 - 2)²)

= √((8)² + (-7)²)

= √(64 + 49)

= √113 units.

Step 5: Calculate the perimeter.

The perimeter is the sum of all four sides:

= AB + BC + CD + DA

= 4 + √65 + 4 + √113

≈ 4 + 8.06 + 4 + 10.63

≈ 26 units.

Therefore, the perimeter of the parallelogram defined by the given vertices is approximately 26 units.
