∠YXZ and ∠ZXW are adjacent and supplementary angles. If m∠YXZ = 37°, what is m∠ZXW?

tensa zangetsu [6.8K]

Answer: Choice A) 143 degrees

To get this answer quickly, you subtract the given angle (37) from 180 to get 180-37 = 143

The more longer answer would look something like this
x+37 = 180 .... the two supplementary angles add to 180 degrees
x+37-37 = 180-37 .... subtract 37 from both sides
x+0 = 143
x = 143
where x is the measure of angle ZXW

A culture of bacteria has an initial population of 41000 bacteria and doubles every 5 hours. Using the formula P t = P 0 ⋅ 2 t d

Crazy boy [7]

Answer:

Population of bacteria in culture after 14 hours is 285541.

Step-by-step explanation:

We are given with $P_{t} =P_{0}(2)^{\frac{d}{t}}$

Here initial population is 41000 , t=5 and d=14

Plug in these values into the formula

$P_{14} =41000(2)^{\frac{14}{5} }$

Simplify

$P_{14}= 41000(2)^{2.8}$

=41000(6.9644)

=285540.5847...

To the nearest whole number is 285541.

Which is the equation of a line that has a slope of -2/3 ans passes through the point (-3, -1)

kupik [55]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - $\frac{2}{3}$ , hence

y = - $\frac{2}{3}$ x + c ← is the partial equation

To find c substitute (- 3, - 1) into the partial equation

- 1 = 2 + c ⇒ c = - 1 - 2 = - 3

y = - $\frac{2}{3}$ x - 3 ← is the equation of the line
