Answer:

D = A < D < B < C

Step-by-step explanation:

A = 4.6 x 10-4

Can be written as,

= 0.00046

B = 2.4 x 10-3

Can be written in this form,

= 0.0024

C = 3.5 x 105

Is written as,

350000

D = 6.3 x 10-4

Is also written as,

= 0.00063

A and D are in 4 decimal places and therefore from the 3th decimal place 46 is less than 63 so therefore 0.00046 is less than 0.00063.

B is greater than A and D because B which is 0.0024 is in 3 decimal places. C which is 35000 is the greatest because there are no decimal places and it is in tenth thousand.

So therefore,

A < D < B < C

The sum of all the angles in a triangle is 180°.
There is a right angle -> a 90° angle on the hypotenuse of the largest triangle (the largest being the one that contains both smaller triangles)

To solve this problem, you don't really need to solve y.
Next to the 48° angle, you have two of the same angles, both x variables.
The sum of these three angles has to be 180°48 + 2x = 180 \\ 2x = 180 - 48 \\ 2x = 132 \\ x = 66

Now that we have x, we can calculate the value of z.
We add the value of x and the 90° angle, we later subtract it from 180°

Calculating the value of z:
66 + 90 = 156 \\ 180 - 156 = 24 \\ z = 24

If you really want to know the value of y, you just add up the 90° angle and the 48°, then subtract that from 180°
90 + 48 = 138 \\ 180 - 138 = 42 \\ y = 42

What is the perimiter, in feet, of a square whose area is 121 square feet
Ainat [17]

Square needs to have all equal sides and length and width are the same.

So sqrt the area.

sqrt 121 = 11

11 feet is the length of one side, square has 4.

So

11 * 4 = 44

The perimeter of a square (whose area is 121 feet) is 44 feet.

(-0.25x -8)-(5.5x + 9.4) the simplified expression
Alja [10]

Answer:

=−5.75x−17.4

Step-by-step explanation:

=−0.25x−8+−1(5.5x+9.4)

=−0.25x+−8+−1(5.5x)+(−1)(9.4)

=−0.25x+−8+−5.5x+−9.4

another way >>>><<<<

=−0.25x+−8+−5.5x+−9.4

=(−0.25x+−5.5x)+(−8+−9.4)

=−5.75x+−17.4

Answer:

=−5.75x−17.4

PLEASE HURRY!!!!!!<br> 10 points !!!!!!!!!!! What is the value of x??
horsena [70]

Answer:

x = 98°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle and 53° and 45° are the opposite interior angles, hence

x = 53° + 45° = 98°
