Answer:

100 degrees

Step-by-step explanation:

We can start by finding angle y, which is supplementary to 160.

180-160=20

angle y = 20 degrees.

With that, we can find angle w using the interior-exterior sangle theorem (or whatever name you use for it) which states that "the measure of an exterior angle of a triangle equals the sum of the measures of two remote interior angles". In other words:

angle w = angle y + 80

angle w = 20+80

angle w = 100.

The final answer is 100 degrees.

I hope this helped! :D

Answer:

Hello,

w=100

Step-by-step explanation:

y=180-160 (angles supplementaries)

y=20

w is a externel angle of the triangle is equal to the sum of non adjacents angles:

w=80+20=100

PLEASE HELP!!!!! 13. PTS+ PLEASE SUPER EASY
Brums [2.3K]

Answer:

1. A. Set the angle and arc measures equal.

2. B. major arc

3. B. Multiply the angle measure by 2.

4. A. minor arc

Step-by-step explanation:

1. If the intercepted arc is made from a central angle then angle of arc is equal to the central angle

2. 190 is a bigger angle than 170(angle of the remaining arc)

   Therefore it is a major arc.

3.If the intercepted arc is made from a inscribed angle, then the angle of arc is double of the inscribed angle.

4. 115 < 245

   Therefore it is a minor arc.

We suspect the overall mean monthly rent of apartments in Shadyside is higher than in Oakland, so we survey a random sample of O
Mars2501 [29]

Answer:

e. Two-sample t-test.

Step-by-step explanation:

This is simply because you only have interval level of measure and you are comparing two populations.

Moreso, this hypothesis test is used to determine questions related to the mean in situations where data is collected from two random data samples. The two sample T-test is often used for evaluating the means of two variables or distinct groups, providing information as to whether the means between the two populations differs. It also can be used to compare the responses of males and females who have each received different treatment within an experiment.

The greatest common factor of 4a(2) b and 6ab(3)
Yuliya22 [10]
4a^2b and 6ab^3

first, find the greatest common factor of ur coefficients 4 and 6.....and that is gonna be 2

as for ur variables and exponents....take the lowest ones

so both have an " a " and a " b " variable....the lowest a term is just " a "...and the lowest " b " term is b

so the GCF of these 2 terms are : 2ab

Taylor can clean pools at a constant rate of 2/5 pools per hour. What is the ratio of pools to hours? HELPP PLEASE
Hatshy [7]

Hi! I'm happy to help!

To solve for this, we need to understand what a ratio is. A ratio is a comparison between two things. (in numbers) In this case,  between pools and hours:

pools:hours

A fraction is also a ratio, in this case we have 2/5, which also compares pools to hours, so we can turn this into a more proper ratio form:

2 pools: 5 hours

2:5

<u>So, our ratio of pools to hours is 2:5.</u>

I hope this was helpful, keep learning! :D

A bowling alley has a fixed base cost and charges a variable per game rate. It costs $20.50 for five games and 28.50 for nine ga
lbvjy [14]


As ordered pairs ( g , C ) where g is the number of games and C is the cost

( 5, 20.50) and ( 9, 28.50)

the slope M = ( 28.50 - 20.50 ) / (9-5)

= 8/4

= 2

So the slope M=$2 per game

Using (5, 20.50)
The intercept B = y - m* g
= 20.50 - 2 * 5
= 20.50 - 10
= 10.50

So the fixed base cost, or FLAT RATE is $10.50.
That is if they played ZER0 games, they still have
to pay $10.50 just to get in.

The linear function is C (g) = 2*g + 10.50
