45 +2.50m = 3.75m what is the answer

zhannawk [14.2K]

m = 36

Work

45 + 2.50m = 3.75m

-3.75m -3.75m

45 - 1.25m = 0

- 45 - 45

-1.25m = -45

-1.25 -1.25

m = 36

The population of Portland Oregon has recently grown to more than 500,000. What is the order of magnitude for the number of peop

miss Akunina [59]

Answer:

Order is 6

Step-by-step explanation:

The population of Portland Oregon has recently grown to more than 500,000.

The order of magnitude for the number of people in Portland means the power of 10. It means that we need to write 500,000 in form of 10 to the power. So,

$P=500,000$

It contains 6 zeroes. It means,

$P=5\times 10^6$

So, the order of magnitude for the number of people in Portland is 6.

Quadrilateral ABCD is inscribed in this circle.

Svetllana [295]

Answer:

132°

Step-by-step explanation:

Quadrilateral ABCD is inscribed in a circle,

So, it is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

$\implies \: x \degree + (3x - 12) \degree = 180 \degree \\ \\ \implies \: (4x - 12) \degree = 180 \degree \\ \\ \implies \: 4x - 12 = 180 \\ \\ \implies \: 4x = 180 + 12 \\ \\ \implies \: 4x = 192 \\ \\ \implies \: x = \frac{192}{4} \\ \\ \implies \: x = 48\\\\$

(3x-12)° = (3*48 - 12)° = (144 - 12)° = 132°

$\implies \: m\angle B = 132\degree\\\\$
