Area of sector

$= \frac{30}{360} \times \pi \times {(radius)}^{2}$

$= \frac{30}{360} \times \ \frac{22}{7} \times {(12)}^{2}$

$= \frac{30}{360} \times \ \frac{22}{7} \times 12 \times 12$

so the area = 37.71 square metre

None of your options

Step-by-step explanation:

$(7 - 3i) + ( x - 2i)^2 -(4i^2 + x^2)\\\\(7 - 3i) + (x^2 - 4 - 4xi) - (-4 + x^2)\\\\7 - 3i + x^2 - 4 - 4xi + 4 - x^2\\\\7 -i(3+4x) - 4 + 4 - x^2 + x^2\\\\7 - (4x + 3)i$

Cal is measuring temperature changes in four substances over different time periods as part of a school project. Which data show

djyliett [7]

Answer:

C) The third table. K= 5

$C)\frac{10}{2}=\frac{15}{3}=\frac{25}{5}=\frac{40}{8}=k= 5$

Step-by-step explanation:

1) Below there are the missing data:

A proportional relationship through a constant k. It is obtained when we divide:

$k=\frac{y}{x}$

2)In this case, when we divide the temperature (T) by the time (h).

$k=\frac{T}{h}$

3)So, examining the table below we are searching for a ratio k common to all measures (temperatures over hour).

$A) \frac{12}{3}\neq\frac{25}{5}\neq\frac{36}{6}\neq\frac{81}{9}\\B) \frac{22.5}{3}\neq\frac{30}{4}\neq\frac{52.5}{7}\neq\frac{67.5}{8}\\C)\frac{10}{2}=\frac{15}{3}=\frac{25}{5}=\frac{40}{8}=k= 5\\D)\frac{8.5}{2}\neq\frac{22.5}{5}\neq\frac{28.5}{7}\neq\frac{36}{8}$

Please help, I'm running out of points.

aksik [14]

Answer:

−5 < x < 10

Step-by-step explanation:

Add 1 to each part of the three parts of the inequality:

-6 +1 < x - 1 +1 < 9 +1

-5 < x < 10 . . . . . simplify

_____

The only place where there's an x is in the middle section. The only operation performed on x is subtraction of 1. To undo that subtraction, you add 1, but you must add 1 to all sides of the comparison symbols in order to keep them true.

Such a compound inequality is the same as the two inequalities:

-6 < x-1
x-1 < 9

Solving either one of these is done by adding 1 to both sides of the < symbol:

-5 < x
x < 10

You can put these back together in the form of the compound inequality ...

-5 < x < 10
