Answer:

9.29 x 10^-2 it's wrong. It's 9.29 x 10^2 (positive)

Step-by-step explanation:

You can "move" or change the measure of everything using some scales based on specific boards.

There's a way to move from the imperial system (yards, feet, inches) to the metric system ( centimeters, meters, kilometers)

1 square foot = 929.03 square centimetre

929.03 can be written with the scientific notation, taking care of the significant figures like $9.29x10^{2}$

3 $feet^{2}$ = 2787.09 $cm^{2}$ or $27.87x10^{2}$ $cm^{2}$

The sum of the measures of angle M and R are complemetary. The measure of the angle M is (5×+90). The measre of angle R is 55. W

Alexandra [31]

Answer:

The value of x is - 11

Step-by-step explanation:

Given as :

∠ M = (5x +90) °

∠ R = 55°

The sum of measure of angle M and R are complementary

Complementary Angle are those when sum of two angle equal to 90°

∵ Angle M and R are complementary in nature

∴ ∠ M + ∠ R = 90°

Or, (5x +90) ° + 55° = 90°

Or, 5x = 90° - 90° - 55°

Or, 5x = - 55°

∴ x = - $\frac{55}{5}$ = - 11

Hence the value of x is - 11 Answer

A Japanese beetle has length between 0.3 and 0.5 inches.Find two lengths that are within the given span. Write them as fraction

Wittaler [7]

<span>A Japanese beetle’s length are equals to
=> 0.3 inches
=> 0.5 inches

Now let’s find the length that is between the span of the two given length:
But before that let’s convert the 2 given numbers in decimal points to fraction:
=> 0.3 = 3/10
=> 0.5 = 5/10

Find the fraction between the given 2 numbers:
=> 0.3
=> 0.4
=> 0.5

Therefore the number we are looking 0.4
=> 0.4 = 4/10
Now, we have the complete length of Japanese beetles, the 0.3, 0.4 and 0.5</span>

Answer: 102 degrees

Step-by-step explanation:

The remote angle theorem is that two remote angles are equivalent to the exterior angle. Both 51 degrees are remote angles, and angle 4 is the exterior.

51 + 51 = Angle 4

Angle 4 = 102 degrees
