Square are the same size all the way around, which means every side = x + 4

The perimeter of a square = 4 * side

the perimeter = 44 cm

Let's plug our values into the formula above.

44 cm = 4 * (x + 4)

Distribute the 4

44 cm = 4x + 16

Subtract 16 from both sides

28 cm = 4x

Divide both sides by 4

7 = x

What is the value of z?

Reil [10]

Answer:

The angle z is 130 degrees.

Step-by-step explanation:

A straight line is 180 degrees.

Now think about how that line looks, you cut 50 degrees off of the whole 180.

So the equation is 180-50=z

z=130

I hope I have been of assistance to you, have a good day.

100 points for right answer Identify the correct explanation for why the triangles are similar. Then find SQ and TP.

STALIN [3.7K]

Answer:

Second one

Step-by-step explanation:

They have one angle (R) in common

Also,

Angles T & S and P & Q are equal because they are corresponding angles.

RS/RT = SQ/TP

4/(4+4) = 2x/(x+6)

4x = x + 6

3x = 6

x = 2

SQ = 2(2) = 4

TP = 2 + 6 = 8

Theo correctly answered 40 out of 50 questions on his spelling quiz. What percent of the questions did theo answer correctly? Ex

Ugo [173]

Theo got an 80% on the quiz because you multiply to get a equivalent fraction since a hundred is a whole of a percent. So basically, the percent is 80% and the decimal is 0.80.

Hope it helps!

A game has a circular playing area in which you must hit a ball into a circular hole. The area of the playing area is 16ft2. The

frez [133]

Considering the area of the hole, it is found that there is a 4.9% probability of hitting a ball into the circular hole.

<h3>What is the area of a circle?</h3>

The area of a circle of radius r is given by:

$A = \pi r^2$

In this problem, the hole has a diameter of 1 ft, hence it is radius is of r = 1 ft/2 = 0.5 ft, and it's area is given by:

$A = \pi \times (0.5)^2 = 0.7854 \text{ft}^2$

Hence the probability is given by:

p = 0.7854/16 = 0.049 = 4.9%
