Answer:

11. x = 8

12. x = 15

13. x = 9

Step-by-step explanation:

This statement of the applicable relation is perhaps a little different than the one(s) you may have seen: From the point where the segments meet, the product of the length of segment to one side of the circle and the length of segment to the other side of the circle is the same for both segments. When the segment is tangent to the circle, those two circle intersection points are the same point.

This rule is applicable for all of these problems. Once the relation is written, the equation can be divided by the coefficient of x to find the value of x.

<h3>11.</h3>

12·4 = 6x

x = 48/6 = 8

__

<h3>12.</h3>

x·x = 9·(16+9)

x = √(9·25) = 15 . . . . take the square root

__

<h3>13.</h3>

x·16 = 8·(8+10)

x = 144/16 = 9

The school cafeteria seats 250 students. 203 students are already seated. Write and sole an inequality that represents the addit

Nitella [24]

Answer:

An equation that represents the given situation is $203+x=250$ and the additional number of students that can be seated is 47

Step-by-step explanation:

Number of students already seated in school cafeteria = 203

Let x be the additional number of students that can be seated

So, Total number of seats available in school cafeteria = 203+x

We are given that the school cafeteria seats 250 students

So, 203+x=250

$\Rightarrow x=250-203$

$\Rightarrow x=47$

Hence an equation that represents the given situation is $203+x=250$ and the additional number of students that can be seated is 47

A car initially traveling at 20 kilometers per hour takes 10 seconds to speed up to 70 km/hour. At what rate is it changing spee

Snezhnost [94]

Initial velocity=u=20km/h
Final velocity=v=70km/h
Time=10s=t

Convert speeds to m/s

$\\ \rm\longmapsto u=20\times\dfrac{5}{18}=5.05m/s$

$\\ \rm\longmapsto v=70\times \dfrac{5}{18}=19.4m/s$

$\boxed{\sf Acceleration=\dfrac{v-u}{t}}$

$\\ \rm\longmapsto Acceleration=\dfrac{19.4-5.05}{10}$

$\\ \rm\longmapsto Acceleration=\dfrac{14.3}{10}$

$\\ \rm\longmapsto Acceleration=143m/s^2$

Step-by-step explanation:

p + 9 - 9 ÷ q - 9

p = 4 q = 3

= 4 + 9 - 9 ÷ 3 - 9

= 4 + 9 - 3 - 9

= 1
