Answer:
y = 98
z = 21
Step-by-step explanation:
in the picture, y and 82 are supplementary angles because the are same side interior angles. This means that we can create this equation:
y = 180 - 82
we get y = 98
<Y and <4z + 14 are vertical angles, so we can also say that they are equal to each other. So we can create this equation:
4z + 14 = 98
subtract 14 from both sides:
4z = 84
divide both side by 4 to find z:
z = 21
Answer:
y = 82
z = 21
Step-by-step explanation:
You can get y almost immediately.
82 and y are supplementary. Interior angles on the same side of the transversal = 180
82 + y = 180 Subtract 82 from both sides
y = 180 - 82
y = 98
y and 4z + 14 are equal.
y = 4z + 14 Substitute for y
98 = 4z + 14 Subtract 14 from both sides.
98-14 = 4z
84 = 4z Divide by 4
84/4 = 4z/4
21 = z

Step-by-step explanation:
Convert to slope-intercept form:
2x-y=6
-y=6-2x
y=-6+2x
y=2x-6
Since y=mx+b is the form we want, then b=-6, making the statement true.
Answer:
true
Step-by-step explanation:
you switch the 2x to the other side to get -y = 2x + 6
then you multiply everything by -1 to get y = -2x-6

abc=80, abm= 100
acb= 40, acn= 140
angle a = 60
x=80, y=40
Answer:
x = 80° y = 40°
Step-by-step explanation:
ABC = 80° ACB = 40°
ABC+ACB+A = 180° (sum of angles in a triangle = 180°)
80+40+A = 180°
A = 60° (sum of angles in a triangle = 180°)
X = 80° (ALTERNATE ANGLES, angles x is alternate to angle ABC = 80° )
y = 40° (alternate angles, angle y is alternate to angle ACB = 40°)
to cross-check : sum of angles on a straight line = 180°
x+ y + A = 180sum of angles on a straight line = 180°
80+40+60 = 180°
ABM = 100° = (sum of angles on a straight line = 180°)
80° + 100° = 180°
ACN = 140° (sum of angles on a straight line = 180°)
40° + 140° = 180°

MY NOTES ASK YOUR TEACHER Jack has decided to advertise the sale of his car by placing flyers in the student union and the dining hall of the college. He estimates that there is a probability of 0.4 that a potential buyer will read the advertisement and that, if it is read, the probability that the reader will buy his car will be 0.1. Using these estimates, find the probability that a potential buyer will read the ad and will buy Jack's car.
Answers
Answer:
The probability that a potential buyer will read the advert and will buy Jack's car is 0.04
Step-by-step explanation:
Estimate 1: There's a 0.4 probability that a potential buyer will read the advert.
Estimate 2: There's a 0.1 probability that whoever reads the advert will buy his car.
- As you can see, the probability of success of this event decreases; from the point of Jack placing an advert, to the point of someone purchasing his car.
- That someone reads the advert does not mean that he or she would be interested in or capable of purchasing the car.
- That someone has the capacity to buy the car (potential buyer) does not mean they'll eventually buy it.
- So altogether, there is a low probability of each reader purchasing the car, and that's 0.1
In the calculation of probability, "and" represents multiplication. Hence,
0.4 × 0.1 = 0.04
The length of a box as reported by its manufacturer is 13.67 cm. Joe has a ruler which has markings for each millimeter. Which most likely represents the length of the box that Joe is able to measure?
Answers
Answer:
Option (3)
Step-by-step explanation:
Joe has a ruler which has markings for each millimeter, so the least measurement which Joe can do is in millimeter.
Since, 10 mm = 1 cm
Therefore, 1 mm = 0.1 cm
This rule states that Joe can measure a length or distance in nearest tenth of a cm only.
If length of a box = 13.67 cm,
So Joe can measure it as 13.7 cm approximately.
Therefore, Option (3) will be the answer.

We start with 550 pieces of candy.
We know that for each kid that comes, the total number of candy will be reduced in 5 units.
Then if there are x children that came to take candy, the total number of candy left will be:
f(x) = 550 - 5*x
That is the function that represents this situation.
Now we want to find the zero of this function, this will be the value of x such that f(x) = 0.
So we only need to solve the equation:
f(x) = 0 = 550 - 5*x
5*x = 550
x = 550/5 = 110
The x-intercept will be (110, 0)
In this particular case, the information on the zero represents the number number of kids that must come and take candy in order to have no more pieces left in the bowl.

The formula for the lateral area of a right cone is LA = πrs, where r is the radius of the base and s is the slant height of the cone. Which are equivalent equations? Select two correct answers.
a) s = s equals StartFraction L A Over pi r EndFraction.
b) s = s equals StartFraction pi r Over L A EndFraction.
c) s = LAr
d) r = r equals StartFraction L A Over pi s EndFraction.
e) r = LAs
Answer:
a) s equals StartFraction L A Over pi r EndFraction.
d) r = r equals StartFraction L A Over pi s EndFraction.
Step-by-step explanation:
The formula for the Lateral Surface Area of a right cone is given in the question as:
LA = πrs
Where
r is the radius of the base and s is the slant height of the cone.
From the options given,
We can make s the subject of the formula.
Hence:
Making s the subject of the formula
LA = πrs
Divide both sides by πr
s = LA/πr
Hence: Option a) s equals StartFraction L A Over pi r EndFraction. Is correct.
Step 2
Making r the subject of the Formula
LA = πrs
Divide both sides by πs
r = LA/πs
Hence: Option d) r equals StartFraction L A Over pi s EndFraction. Is correct.
