He should use the Pythagorean Theorem to find the missing length.

Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.

So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5

Therefore, the radius of circle L is 5 feet.

Ok i forgot how to do this.

Well, the first dot is the known as the Minimum. Then, the second dot is the 1st Quartile. The dot in the middle of the box with the line through it is the median (2nd Quartile). Then the last dot forming the box is the 3rd Quartile. And the final dot is the 4th Quartile (Also known as the Maximum). In this case, it is asking about the Median...which would be 15.5. Hope this helped!

A rectangular tank measures 16 cm by 9 cm by 10 cm. How many milliliters of water are in the tank when it is full? How many lite

trapecia [35]

Answer:

1,440 cubic centimeter = 1,440 milliliters

1,440 cubic centimeter= 1.44 liters

Step-by-step explanation:

Volume of the rectangular tank = length × width × height

Length = 16 cm

Width = 9 cm

Height = 10 cm

Volume of the rectangular tank = length × width × height

= 16 cm × 9 cm × 10 cm

= 1,440 cm³

Volume of the rectangular tank = 1,440 cm³

How many milliliters of water are in the tank when it is full?

1 cubic centimeter = 1 milliliter

1,440 cubic centimeter = 1,440 milliliters

How many liters?

1 cubic centimeter = 0.001 liters

1,440 cubic centimeter= 1.44 liters

35 solve the following syste

blondinia [14]

Part A: The solution is $(-0.923,5.692)$

Part B: The point $(3,7)$ is not in the solution set.

Explanation:

Part A: The given inequalities are $3 x+4 y>20$ and $x$

The solution can be determined by solving the two inequalities by substitution method.

Changing inequalities to equality, we have,

$x=3 y-18$ and $3 x+4 y=20$

Let us substitute $x=3 y-18$ in the equation $3 x+4 y=20$ , we get,

$3 (3y-18)+4 y=20$

$9y-54+4y=20$

$13y=74$

$y=5.692$

Substituting $y=5.692$ in $x=3 y-18$ , we get,

$x=3 (5.692)-18$

$=17.076-18$

$x=-0.923$

Thus, the solution set is $(-0.923,5.692)$

Part B: Now, we shall determine whether the point $(3,7)$ is in the solution set.

Let us substitute the point $(3,7)$ in the inequalities $3 x+4 y>20$ and $x$ , we get,

$3 (3)+4 (7)>20$

$9+28>20$

$37>20$

Also, substituting $(3,7)$ in $x$ , we get,

$3$

$3$

$3$

Since, the point $(3,7)$ does not satisfy one of the inequality $x$ , the solution set does not contain the point $(3,7)$

Thus, the point $(3,7)$ is not in the solution set.
