Answer:
hours
Step-by-step explanation:
Whenever 2 quantities (suppose a and b) are inversely proportional to each other, we can write an proportionality equation (with k as proportional constant) as:

Since, here t is INVERSELY PROPORTIONAL to r, we can say:

Firstly, we have t = 2 hour and r = 40 mph, so we find k:

Now, secondly, we have r = 45 and k = 80, we need to find t:

So, it would take
hours
P+q= 5x^2+2
q-p= -(x-2) (x+2)
Answer:
3x - 4 = 32
Step-by-step explanation:
We solve for x to find the number (knowing that x is the unknown number).
3x - 4 = 32
3x = 32 + 4
3x = 36
x/3 = 36/3
x = 12
Answer:
[A] The corresponding sides of the triangles are congruent.
[B] The corresponding angles of the triangles are congruent.
[C] The triangles have the same size.
[D] The triangles have the same shape.
Step-by-step explanation:
SAS which it is stands for {side, angle, side} and the meaning of SAS is that we have two triangles where we see two sides and the included angle are equal.
In Order for two triangles to be congruent must have the following below:
- Two figures are said to be congruent if they have same size and same shape.
- If two figure are congruent that means the corresponding sides will also be congruent.
- If two figure are congruent that means the the corresponding angles will also be congruent.
Hence, base on the given all the following are correct:
A. The corresponding sides of the triangles are congruent. √
B. The corresponding angles of the triangles are congruent. √
C. The triangles have the same size. √
D. The triangles have the same shape. √
