A grid of a hundred square show 7 shaded squares what decimal number is represented​
Tems11 [23]

Answer:

0.07

Step-by-step explanation:

From the question, a given grid was divided into a definite number of squares with some of the squares shaded.

Total number of squares in the grid = 100

number of shaded squares in the grid = 7

Thus, 7 squares are shaded out of 100 square in the grid.

So that this can be expressed in fraction as;

\frac{number of shaded squares}{total number of squares} = \frac{7}{100}

                                = 0.07

The decimal number of the squares represented is 0.07.

How do I find dis?<br> 180 rotation about the point (1,4)
prohojiy [21]

Answer:

When we rotate a point A(1, 4) 180 degrees counterclockwise about the origin, the coordinates of point A(1, 4) transformed to A'(-1, -4).

Step-by-step explanation:

We know that 180 Degree Rotation.

We know that when we rotate a point, let say P(x, y), 180 degrees counterclockwise about the origin, the coordinates of point P(x, y) transformed to P'(-x, -y).

In other words, the sign of both x and y coordinates are reversed.

Thus, the rule is:

P(x, y) → P'(-x, -y)

Given the point (1, 4)

P(x, y) → P'(-x, -y)

A(1, 4) → A'(-1, -4)

Thus, when we rotate a point A(1, 4) 180 degrees counterclockwise about the origin, the coordinates of point A(1, 4) transformed to A'(-1, -4).

HURRY Given f(x) = - 3/4x + 2, find ƒ(16). The solution is
BaLLatris [955]

Answer:

\fbox {f(16) = -10}

Step-by-step explanation:

<u>Given</u> :

f(x) = -3/4x + 2

<u>Substitute x = 16</u> :

f(16) = -3/4(16) + 2

f(16) = -12 + 2

f(16) = -10
