Answer:
1. No, Student 1 did not make any errors. However, their use of a ruler, or lack of thereof, could result in a lack of accuracy.
2. The student manually found the points and connected them together, doing so for both A and B and thus finding the intersection.
3. Since there is no formula used, the result may not be accurate. The student can only guess the position of the intersection, not know exactly (i.e. when the points are positioned at decimal numbers.)
1.)9a+4c=43
2.)4 adults and 4 children
3.)27$
4.)y=.10+40
5.)y=.20x+18
That's all I have so far
(I think 6.) is 193 but I'm not positive)
Answer:
90 degree
Step-by-step explanation:
Let represent the measure of the third angle. Then, − can represent the measure of the second angle. The
sum of the two angles in the right triangle will be °.
− + =
− =
− + = +
=
=
=
The third angle is and therefore measures °. Replacing with in − gives () − = − = .
Therefore, the measure of the second angle is °. The measure of the third angle is °.
Answer:
3.) a. 9mm b. 10mm c. 8mm
Step-by-step explanation:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.
Formula:
a + b = (answer) > c
a + c = (answer) > b
b + c = (answer) > a
try to solve it yourself so you can do it on your own in the future.
