Answer:
AC = 18.1 cm
Step-by-step explanation:
Construct a line from point B perpendicular to the line AD and mark it as E on line AD. Now you have a right triangle ABE with AB = 16 cm and AE = AD - BC
so AE = 11 cm - 4 cm = 7 cm
You can find BE by using Pythagorean theorem
BE^2 = AB^2 - AE^2
BE^2 = 16^2 - 7^2
BE^2 = 256 - 49
BE^2 = 207
BE = 14.4 cm
Draw a line from A to C, you have a right triangle ACD with AD = 11cm and CD = BE = 14.4 cm
Using Pythagorean theorem
AC^2 = AD^2 + CD^2
AC^2 = 11^2 + 207
AC^2 = 121 + 207
AC^2 = 328
AC = 18.1 cm
Answer:
2, your most gracious highness, superior leader of the Northern hemisphere
Step-by-step explanation:
Answer:
y = -2
Step-by-step explanation: You have to substitute 1 for x since x = 1/
SOOO...
4x + 3y = -2
4(1) + 3y = -2
4 + 3y = -2
-4 -4
<u>3y = -6</u>
3 3
y = -2
- Remember, a number times 1, is the number itself. Like for example, 1 x 400, that'll equal 400, because anything times 1 is itself.
- Remember, a negative plus another negative becomes a negative
Hope this helps you!!!! :)
A linear equation that represents the model is: x + 6 = 10; x = 4
<h3>How to solve linear equations?</h3>
Let us first define the variables based on the attached image of the ball balance:
Let x = number of balls that contains the square.
On the left side, we have; square + 6 balls
On the right side, we have; 10 balls
To balance this, we have;
x + 6 = 10
x = 10-6
x = 4
Thus, a linear equation that represents the model is:
x + 6 = 10; x = 4
