Using supplementary angles, it is found that the measures of the angles are given as follows:

m<a = 30º.

m<b = 90º.

<h3>What are supplementary angles?</h3>

Supplementary angles are two angles whose sum is of 180º.

An interior angle is supplementary with it's exterior angle, hence:

m<a + 150º = 180º -> m<a = 30º.

The sum of the three interior angles of a triangle is of 180º, hence:

30º + m<b + 60º = 180º

90º + m<b = 180º

m<b = 90º.

Five more than the quotient of a number and 3 equals 2.

MakcuM [25]

Answer:

$\large\boxed{\dfrac{n}{3}+5=2\ or\ n:3+5=2}$

Step-by-step explanation:

$\dfrac{n}{3}+5=2\\\\\dfrac{n}{3}-\text{the quotient of a number}\ n\ \text{ and 3}\\\\...+5-\text{five more than}$

If you want a solution:

$\dfrac{n}{3}+5=2$ <em>subtract 5 from both sides</em>

$\dfrac{n}{3}+5-5=2-5$

$\dfrac{n}{3}=-3$ <em>multiply both sides by 3</em>

$3\!\!\!\!\diagup\cdot\dfrac{n}{3\!\!\!\!\diagup}=(3)(-3)\\\\n=-9$

On a snow day, Jada created two snowmen in her yard. Snowman A was built to a height of 51 inches and Snowman B was built to a h

MaRussiya [10]

From the graph of the linear functions, we have that both snowman's will have the same height of 21 inches after 5 hours.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, we have that:

The initial height is the intercept.

The melting rate, as a negative, is the slope.

Hence the functions are given as follows:

A(t) = 51 - 6t.

B(t) = 36 - 3t.

The functions are graphed at the end of the answer, with <u>A(t) in red and B(t) in blue,</u> and they intersect at (5,21), meaning that both snowman's will have the same height of 21 inches after 5 hours.

A cup of coffee at 85 degrees Celsius is placed in a room at 25 degrees Celsius. Suppose that the coffee cools at a rate of 5 de

bezimeni [28]

Answer: k = - 6.6667

Step-by-step explanation:

this is quite very simple to begin. I would encourage you take other practice questions similar to help with understanding it.

let us begin.

Given that ;

dT/dt = k ( Tm - T) where Tm is the temp of the medium

dT/dt = 5 degrees Celsius per minute when T = 70

so we have that, 5 = k ( 25 - 70)

remember to convert 5 degree celsius per minute to seconds

we have that;

5*60(sec) = k ( 25 - 70)

k = 5*60 / ( 25 - 70)

k = - 6.6667

note K is negative because we consider it for cooling process (temp decreasing).

cheers i hope this helps!!!
