Answer:

1.47 mm

Step-by-step explanation:

In week 1 there was 2.6 mm

In week 4 there was 4.07

You want to find the difference of week 1 and 4 meaning you have to subtract week 4's value from week 1's to find how much more rain there was in week 4 than week 1

You would do 4.07-2.6

This is equal to 1.47

THEREFORE there was 1.47 mm more rain in week 4 than week 1

The larger square is composed of 16 smaller squares. Find the length of the sides of Square "a".

kondaur [170]

Answer:

2.5 ft.

Step-by-step explanation:

The area of the side of each smaller square = 100 / 16 sq ft.

= 6.25 sq feet.

So the length of each smaller square = square root of 6.25

= 2.5 ft.

A motion sensor has a range of 65 meters as shown. The ultrasonic waves sweeping out from the sensor span an angle of 135°.

VMariaS [17]

The approximate area that is within range of the motion sensor is 4975 square meters

<h3>How to determine the area of the range?</h3>

The figure is not given, however the area of the range can be calculated without the figure.

The given parameters are:

Angle, ⊕ = 135°

Radius, r = 65 meters

The area of the range is calculated using the following sector area

$A = \frac{\theta}{360} * \pi r^2$

This gives

$A = \frac{135}{360} * 3.14 * 65^2$

Evaluate

A = 4974.9375

Approximate

A = 4975

Hence, the approximate area that is within range of the motion sensor is 4975 square meters

Shannon saves 1235 in november. In november, she saved $250 less than she did in december. How much money did she save in the tw

madam [21]

In December she would have saved $1585 because 1235 + 250 = 1485. You can find how much money she raised in those 2 months by adding the totals of both months together, so 1485 + 1235 = 2720. She saved $2720 in the 2 months.

Median- 63
mode-60
to find the median you arrange the values from the lowest to highest value, then you find the MIDDLE number.. if theres two in the middle add them and divide by two.
the mode is the Q3 - Q1 (70-60)
