Answer:

5.4 > x > 2.8

Step-by-step explanation:

Sum of two sides is always greater than the third side

Case1 :

4.1 + 1.3 > x

5.4 > x

Case2:

4.1 + x > 1.3 or 1.3 + x > 4.1

x > 1.3 - 4.1 or x > 4.1 - 1.3

x > - 2.8 or x > 2.8

Note that it is obvious x is not -ve so neglect -2.8. x > 2.8

Hence,

5.4 > x > 2.8

Which criterion can be used to prove ABC and ADC are congruent?

olya-2409 [2.1K]

Triangles have common side AC, and 2 adjacent to this side corresponding angles.
∠BAC=∠DCA, and
∠ACB=∠SAD.
So, triangles ABC and ADC are congruent by ASA.

A tub filled with 50 quarts of water empties at a rate of 2.5 quarts per minute. let w = quarts of water left in the tub and t =

Sholpan [36]

This is a linear relationship. The slope-intercept form of the linear equation is:

$y=mx+c$

Where,

m is the rate of change (positive if increasing rate and negative if decreasing rate)
c is the y intercept, or the initial value

Rate of change is 2.5 quarts per minute (it is decreasing so m is -2.5)

Initial value is 50 quarts, so c is 50.

Plugging in the values we get $y=-2.5x+50$ .

Changing variables to w instead of y and t instead of x, gives us,

$w=50-2.5t$ . Where w is warts of water left in the tub and t is the time in minutes.

There is no viable solution when t=30 because at t=20, w=0 ( $0=50-2.5(20)$ ). It means after 20 minutes, there is no water left. So t=30 minutes doesn't make sense.
