Answer: 9 cm

You can figure this out because the unknown side combined with the 5cm side is equal to the 14cm side. Therefore, subtract 5 from 14 to find out the unknown side.

The missing side is 9cm

The perimeter is 44cm

Explanation:

To find the missing side you subtract 5 from 14 since the missing side added to 5 would have the length of 14.
So, 14-5 = 9

The perimeter is calculated by adding all sides:
14 +8+5+3+9+5= 44

EQAO Watch Sammy and Pippa's teacher gives them a homework question to solve. She tells them to plot the points A(5, -1), B(9, 4

Alona [7]

Answer:

None of them are correct. The shape in their homework is a rectangle

Step-by-step explanation:

I would be determining my answer using Length

To find the length of the sides, when you have vertices (x₁, x₂)and (y₁, y₂) we use the formula

√(x₂-x₁)²-(y₂-y₁)²

A(5, -1), B(9, 4), C(15, 1) and D(11, -4)

Side/ Length AB = A(5, -1), B(9, 4)

√(x₂-x₁)²-(y₂-y₁)²

= √(9 - 5)² + (4 - (-1))²

= √4² + 5²

= √16 + 25

= √41

Side/ Length BC = , B(9, 4), C(15, 1)

= √(x₂-x₁)²-(y₂-y₁)²

= √(15 - 9)² + ( 1 - 4)²

= √6² + -3²

= √36 + 9

= √45

Side/ Length CD = C(15, 1) and D(11, -4)

√(x₂-x₁)²-(y₂-y₁)²

= √(11 - 15)² + (-4 - 1)²

= √-4² + -5²

= √16 + 25

= √41

Side/ Length AD = A(5, -1), D(11, -4)

√(x₂-x₁)²-(y₂-y₁)²

= √(11- 5)² + (-4 - (-1))²

= √6² + 3²

= √36 + 9

= √45

From the Calculations above ,

AB = √41

BC = √45

CD = √41

AD = √45

A square and a rhombus are shapes with 4 sides and all their sides are equal to each other.

From the above calculation, we can see that

We can see that Length AB = Length CD

Length BC = Length AD

This means , the Opposite sides only are equal to each other.

Therefore, none of them is correct. The shape in their homework is a rectangle

Three judges measure the lap times of a runner and each measurement is different from the others by a few hundredths of a second

ohaa [14]

Answer:

Systematic error

Step-by-step explanation:

Assuming that none of the judges are biased, the most likely reason for this difference is the occurrence of systematic errors.

Systematic errors are errors introduced by inaccuracy in the experimental design, be it in the observation or measurement process.

In this case, the reaction time from observing the finish and stopping the clock for each judge might be different, which configures a systematic error.

Example<br>2 (3x+11)=10

Bumek [7]

Answer:

x = -2

Step-by-step explanation:

2 (3x+11)=10

Divide each side by 2

2/2 (3x+11)=10/2

3x+11 = 5

Subtract 11 from each side

3x+11-11 = 5-11

3x = -6

Divide each side by 3

3x/3 = -6/3

x = -2

A builder is installing a Norman window made up of a rectangle topped by a semicircle. If the radius of the semicircle is r, and

Nookie1986 [14]

Notice the picture

the semicircle, has a radius of "r", you can use that to get the area of a circle, then half it, that's the area of that semicircle in "r" terms,

now, look at the rectangle the semicircle is sitting on top of, to make up
the normal window, it has a height of 3r, and notice its width

so, get the area of the semicircle, and the area of the rectangle,
both in r-terms
add them up, and that's the area of the window
