Answer:

n=4

Step-by-step explanation:

(7+1)+n=(4+7)+1

7+1+n=4+7+1 (subtract 7 from both sides)

1+n=4+1

1+n=5

n=5-1 (Subtract 1 from both sides)

n=4

3241004551 [841]

Answer:

The radius is 0.398 feet to produce a perfect lawn for the lawnmower.

It is given that the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet.

It is required to calculate the radius (R) of the pole that will produce a perfect lawn.

What is a circle?

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have,

Width of the lawnmower = 2.5 feet

Length of the rope = 25 feet

For the perfectly mowed lawn, it means the lawnmower width which is 2.5 feet must wrap the pole with radius R, mathematically:

The perimeter of the pole = width of the lawnmower

2πR = 2.5

R = 0.398 Feet ( π = 3.14 )

Thus, the radius is 0.398 feet to produce a perfect lawn for the lawnmower.

Answer: A (5, -5.5)

Step-by-step explanation: To find the midpoint of a line segment, you must know the formations of points. Two coordinates are made up of (x1, y1)(x2, y2). Now, to find the answer, you have to add the two x's (which is 4 and 6 = 10) and divide by 2 which equals 5. Now to find the y point, add both y's together. -5 + -6 = -11, and dividing by 2 gives you -5.5

Thus, the midpoint is (5, -5.5)

A school conducted a survey to find out which games students enjoy watching the most. The table below contains the results of th

uysha [10]

Answer:

The relative frequency of the middle school students who watch soccer the most is 33.3%.

Step-by-step explanation:

We are given the table,

Grade Basketball Baseball Football Soccer Tennis Other Total

Elementary 51 18 26 32 4 6 137

Middle 50 24 44 34 7 18 177

High 42 17 58 36 11 24 188

Total 143 59 128 102 22 48 502

Now, we are required to find the relative frequency of the middle school students who watch soccer.

Since, we know,

Total number of students who watch soccer = 102

Number of middle school students who watch soccer = 34

Thus, the relative frequency of the middle school students = $\frac{34}{102}$ = 0.333 i.e. 33.3%

Hence, the relative frequency of the middle school students who watch soccer the most is 33.3%.
