Answer:
An equilateral triangle is formed.
Step-by-step explanation:
Since you construct two lines of 60° at points P and Q, the two ends of the line, you construct a triangle with two angles as 60°.
Hence, with the knowledge that the angle sum of a triangle is 180°, we can find that the remaining angle is [tex](180\textdegree - 60\textdegree - 60\textdegree)[/tex] = [tex]60\textdegree[/tex].
Therefore, a triangle with all angles at 60° is an equilateral triangle.

A salesperson works 40 hours per week at a job where she has two options for being paid. Option
A is an hourly wage of $22. Option B is a commission rate of 10% on weekly sales. How much
does she need to sell this week to earn the same amount with the two options?
Answer:
the weekly sales are $8,800 to earn the similar amount with the two options
Step-by-step explanation:
The computation is shown below:
The earnings in option A is
= 40 hours × $22
= $880
Now let us assume the weekly sales be x
So the equation would be
10%x = $880
0.10x = $880
x = $8,800
Hence, the weekly sales are $8,800 to earn a similar amount with the two options

What two points are contained in the graph of y = log9 (x)?
O (1,0) and (9, 1)
O(0,1) and (1, 9)
O (1,0) and (9, 0)
O (1,0) and (9, 9)
Answer:
the first choice
Step-by-step explanation:
(1,0) and (9,1)
The graph of a function f is the set of all points (x,f(x)). Any point on the graph satisfy the equation of the graph. To check whether a point lie on a graph we need to put the x value and y value of the point to the equation of the graph and check the LHS and RHS . If LHS is equal to RHS , then this point lie on the graph.
The given equation of graph is y=log₉(x) ...........(i)
Now we check whether the points (1,0) and (9, 1) lie on (i).Putting both the points on the LHS and RHS of (i) we get
For point (1,0) , LHS = 0 and RHS = log₉(1)=0
Therefore LHS=RHS for the point (1,0).
For point (9,1), LHS= 1 and RHS= log₉(9)=1
Therefore LHS=RHS for the point (9,1).
Therefore (1,0) and (9,1) lie on graph of equation (i).
Check whether the points (0,1) and (1, 9) lie on (i).Putting both the points on the LHS and RHS of (i) we get
For point (0,1), LHS=1 and RHS=log₉(0) is undefined
Therefore LHS≠RHS for the point (0,1).
For point (1,9), LHS= 9 and RHS= log₉(1)=0.
Therefore LHS≠RHS for the point (1,9).
Therefore (0,1) and (1,9) does not lie on graph of equation (i).
Check whether the points (1,0) and (9,0) lie on (i).Putting both the points on the LHS and RHS of (i) we get
For point (1,0), LHS=0 and RHS=log₉(1)=0.
Therefore LHS=RHS for the point (1,0).
For point (9,0), LHS= 0 and RHS= log₉(9)=1.
Therefore LHS≠RHS for the point (9,0).
Therefore (1,0) lie on (i) but 9,0) does not lie on graph of equation (i).
Check whether the points (1,0) and (9,9) lie on (i).Putting both the points on the LHS and RHS of (i) we get
For point (1,0), LHS=0 and RHS=log₉(1)=0
Therefore LHS=RHS for the point (1,0).
For point (9,9), LHS= 9 and RHS= log₉(9)=1.
Therefore, LHS≠RHS for point(9,9).
Therefore (1,0) lie on (i) but 9,9) does not lie on graph of equation (i)
Hence, the points (1,0) and (9,1) lie on the graph of y=log₉(x).

A medication contains 5 milligrams/milliliter, and a patient is taking 1 teaspoon of it 3 times daily. How many milligrams of medication is the patient receiving per day?
options:
5 milligrams
7.5 milligrams
75 milligrams
100 milligrams
Answer:
Answer: 75 milligrams
Step-by-step explanation:
The medication contains 5 milligrams/milliliter.
The patient is given 1 teaspoon of the medication 3 times a day. Since 1 teaspoon is approximately equal to 5 milliliters, then the patient takes 3*5 = 15 milliliters of the medication per day.
Each milliliter contains 5 milligrams, thus the patient receives 15*5 = 75 milligrams of medication per day.
Answer: 75 milligrams

Kiran and Clare live 24 miles away from each other along a rail trail. One Saturday, the two friends started walking toward each other along the trail at 8:00 a.m. with a plan to have a picnic when they meet.
Kiran walks at a speed of 3 miles per hour while Clare walks 3.4 miles per hour.
e) After one hour, how far apart will they be?
Answer:
17.6 miles
Step-by-step explanation:
speed = distance/time
distance = speed * time
We multiply the speed of each one by the time, 1 hour, to find the distance each one walked in 1 hour.
Kiran: 3 mph * 1 h = 3 miles
Clare: 3.4 mph * 1 h = 3.4 miles
The total distance they walked is 3 miles + 3.4 miles = 6.4 miles.
After 1 hour, they are 6.4 miles closer than they were at the beginning of the walk.
24 miles - 6.4 miles = 17.6 miles
Answer: 17.6 miles
Yoda Soda is the intergalactic party drink that will have all your friends saying, "Mmmmmm, good this is!"
You are throwing a party, and you need 555 liters of Yoda Soda for every 121212 guests.
If you have 363636 guests, how many liters of Yoda Soda do you need?
liters
Answer:
15 litres
Step-by-step explanation:
Given
5 litres = 12 guests
Required
Determine the number of litres for 36 guests
Represent the required number of litres with L.
So, we have the following relationship:
[tex]5\ litres = 12\ guests[/tex]
[tex]L = 36\ guests[/tex]
Cross Multiply
[tex]L * 12\ guests = 5\ litres * 36\ guests[/tex]
[tex]L * 12= 5\ litres * 36[/tex]
[tex]12L = 180\ litres[/tex]
Solve for L
[tex]L = \frac{180\ litres}{12}[/tex]
[tex]L =15\ litres[/tex]
Hence, 15 litres are needed

The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8200 ft, the liquid boils at 199.42°F. At an altitude of 4700 ft, the liquid boils at 206.07°F. Write an equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet. What is the boiling point of the liquid at 2500 ft?
Write an equation.
b=
Answer:
b=-0.0019a + 215
at 2500 ft, b=210.25 degrees F
Step-by-step explanation:
First find the slope. a=altitude, b = temperature
slope is b2-b1 / a2-a1
points are (8200, 199.42) and (4700, 206.07)
(206.07 - 199.42) / (4700-8200)
= 6.65/ -3500
= - 0.0019
we have b = -0.0019a + intercept
plug in a point to find intercept
199.42 = -0.0019*8200 + intercept
intercept = 199.42 + 15.58 = 215
b=-0.0019a + 215
at a=2500 ft, substitute into equation
b= -0.0019*2500 + 215
= -4.75 + 215
= 210.25 degrees F

Answer:
m < 1 = 72
Step-by-step explanation:
Since we know that line l and line m are parallel and that p is one of their transversals, it sets up a situation where we can identify which angles are congruent (equal) to one another according to their positions.
In this case, we can see that < 3 and < 1 are in the same matching corners created by the transversal. When angles are in the same matching corners they are called corresponding angles - and according to the Corresponding Angles Postulate, corresponding angles are congruent.
Therefore, m < 3 = m < 1, and since it's given that m < 3 = 72, we know that m < 1 = 72 too.
