Answer:
t≅13.33h
Step-by-step explanation:
Adam (A) works at constant rate of 50tiles/h
Briana (B) works at constant rate of 55tiles/h, this means that A=50 tiles per hour and B=55 tiles per hour, then A+B = 105tiles/h together, but the floor consists of 1400tiles, so if 105 tiles are installed in one hour, then 1400 tiles in how long they will be installed?
t = 1400tiles*h/105tiles≅ 13.33 h
Answer:

Step-by-step explanation:
Remember that complementary angles <em>always </em>add up to 90°.
We know that the two complementary angles are represented by (x) and (x+14). In other words:

So, let's solve for x.
First, combine like terms:

Let's isolate the x by subtracting 14 from both sides:

The left cancels. Subtract on the right:

Divide both sides by 2:

The left side cancels. Divide on the right:

So, the value of x is 38°.
And we're done!
No. they change because you are changing the size of the shape
Answer:
Two negative charges will not attract each other.
Step-by-step explanation:
According to the law of electrostatic induction, it states that "Like charges repel, unlike charges attracts.
Charges can either be positive or negative. For the charges to repel, charges with the same sign must be brought together e.g positive-positve or negative-negative.
For the charges to attract, charges with different sign must be brought together e.g positive-negative or negative-positive.
Based on the conclusion above, it can be seen that the table is incorrect because two negatively charged particle will always repel not attract.
