What is a Linear Pair of Angles?When two lines meet at a single point, a pair of linear angles is created. If the angles follow the point where the two lines cross, they are considered to be linear. A linear pair's angles add up to 180° in every case.
Given:
Measures of two linear pairs of angles which are of equal measures are 2x and 11y + 2.
As the sum of linear pair of angles is 180°, and if they are of equal measures, each angle must be equal to 90°.
To determine the values of x and y we equate the given angles to 90°.
2x = 90°
⇒ x = 45
And 11y+2 = 90°
⇒ 11y = 90-2 = 88
⇒ y = 8

a pirate keeps 2/3 of his coins in a treasure chest and distributes the rest equally among three crew members. if each crew member receives 25 coins, how many coins did the pirate keep
ANSWER:
150 coins
STEP-BY-STEP EXPLANATION:
We know that of the total that the pirate initially had 2/3 I keep them in a chest and the rest he distributed, the rest corresponds to 1/3 of the total.
Now, if each one received 25 coins, and 3 three members, it means that 1/3 is equivalent to 3 times 25 coins, that is, 75 coins.
Now, if 1/3 is 75 coins, 2/3 proportionally would be:
[tex]\begin{gathered} \frac{75}{\frac{1}{3}}=\frac{x}{\frac{2}{3}} \\ \text{ solving for x} \\ 225=\frac{3x}{2} \\ x=\frac{225}{3}\cdot2 \\ x=150 \end{gathered}[/tex]Which means that the pirate kept 150 coins in the chest
One angle of an isosceles triangle measures 42°. what measures are possible for the other two angles? choose all that apply.
The measure of second angle and third angle of the isosceles triangle will be equal to 69° each.
What is an isosceles triangle ?
An isosceles triangle is a triangle which has two equal sides and two equal angles.
It is given that the first angle of an isosceles triangle is 42°. In a triangle sum of all angles is equal to 180°.
We know that in an isosceles triangle the measure of two angles and two sides are equal.
The measure of first angle is 42°. Let's assume the measure of second angle is x this meant the measure of third angle will be x too.
∵ Sum of three angles of a triangle = 180°
∴ 42 ° + ( x + x ) = 180°
or
42 ° + ( 2x ) = 180°
2x = 180° - 42°
2x = 138°
or
x = 69°
As measure of both unknown angles is same , so second angle and third angle will have a measure of 69° each.
Therefore , the measure of second angle and third angle of the isosceles triangle will be equal to 69° each.

The unit cost C (the cost in dollars to make each car) depends on the number of cars made. If u cars are made, then theunit cost is given by the function C(x)=1.1x^2638x+103,259. What is the minimum unit cost?Do not round your answer.
The cost function is given as,
[tex]C(x)=1.1x^2-638x+103259[/tex]Obtain the first derivative as,
[tex]C^{\prime}(x)=1.1(2x)-638(1)=2.2x-638[/tex]Obtain the critical points by equating the first derivative to zero,
[tex]C^{\prime}(x)=0\Rightarrow2.2x-638=0\Rightarrow2.2x=638\Rightarrow x=290[/tex]Thus, the Cost function has an extrema at point 290.
Apply the second derivative test,
[tex]C^{\doubleprime}(x)=\frac{d \square}{dx}(2.2x-638)=2.2[/tex]Since the second derivative is positive, the function attains minimum value at the critical point.
Therefore, it is concluded that the cost is minimum at 290.
Substitute the value in the function to obtain the minimum cost,
[tex]C_{\min }=C(290)=1.1(290)^2-638(290)+103259=10749[/tex]Thus, the minimum unit cost is $10749 which corresponds to 290 units of cars.

Answer:
m∠5 = 52°Step-by-step explanation:
Given AB ║ CD and m∠3 = 52°From the diagram we see that ∠3 and ∠5 are alternate interior angles, since located on opposite sides of the transversal.
As per definition, alternate interior angles are congruent and therefore:
∠5 ≅ ∠3, som∠5 = m∠3 = 52°Answer:
m∠5 = 52°
Step-by-step explanation:
Alternate Interior Angles Theorem
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent.
As line AB is parallel to line CD, angles 3 and 5 are alternate interior angles, and are therefore congruent according to the Alternate Interior Angles Theorem.
⇒ m∠5 = m∠3 = 52°

A rocket is launched and the quadratic function h(t) = -5t^2+165t relates the height (h) in meters to seconds (t) after launch. When will the rocket be 450 feet above the ground? (Hint...twice!!!) - this is solved by factoring
h(t) = -5t^2+165t
We need to set this equation to 450
450 = -5t^2+165t
Subtract 450 from each side
450-450 = -5t^2+165t-450
0 = -5t^2+165t-450
Divide each side by -5
0 = t^2 - 33t+ 90
Now factor the right hand side
0 = ( t-3) (t-30)
Using the zero product property
t-3 =0 t-30 =0
t =3 t=30
t=3 is when it =450 on the way up
t=30 is when it = 450 on the way down
