Answer:

  49°

Step-by-step explanation:

The given information that BC=DC tells you triangle BCD is an isosceles triangle and that angle y is one of the two equal base angles. Then ...

  y + y + 82 = 180 . . . . . the sum of angle measures is 180 degrees

  2y = 98 . . . . subtract 82

  y = 49 . . . . . divide by 2

The measure of y is 49°.

A server sees 84 customers over 6 hours. How many customers did they see in 1 hour?
AveGali [126]

Answer: 14 customers

Step-by-step explanation: Right now, you can set up an equation that looks something like this. 6h=84 (h means hours). To find the number of customers in one hour, all you have to do is isolate h on one side of the equation. To do this, just divide both sides by 6 and you should get h=14. So in one hour, this particular server sees 14 people. Hope this helps! :)

The rate constant for this first‑order reaction is 0.740 s − 1 0.740 s−1 at 400 ∘ C. 400 ∘C. A ⟶ products A⟶products How long, i
sesenic [268]

Answer:

1.668 S

Step-by-step explanation:

We are given that

A\rightarrowProduct

For first order reaction,

t=\frac{1}{k}ln\frac{A_0}{A}

t=\frac{2.303}{k}log\frac{A_0}{A}

Rate constant=k=0.740s^{-1}

Temperature=T=400^{\circ}

We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.

A_0=0.79 M

A=0.230

Substitute the values then we get

t=\frac{2.303}{0.740}log\frac{0.79}{0.23}

t=1.668 s

Hence, it would take 1.668 s for the concentration of  A to decrease from 0.790 M to 0.230 M.

Answer:   A. 1.01  Same as 1 1/100  fractions are rational

B. 57  Integers are rational. (Invisible implied denominator is 1)

Step-by-step explanation:  c might be, but the denominator is not specified-- or maybe / is supposed to mean square root. So probably not.

D. NO, non-repeating decimal numbers are irrational
