What is the value of K?
M
115
Y
(4k+5)
(6k + 10)
X
Answer: 10
Step-by-step explanation:
The value of k is 10.5.
What is meant by angle ?An angle is a shape created by two rays or lines that meet at the same terminal.
Here,
∠XZY = (4k + 5)°
∠YXZ = (6k + 10)°
The exterior angle M = 115°
Therefore,
∠XYZ = 180 - 115
∠XYZ = 60°
So, we can write that,
∠XZY + ∠YXZ + ∠XYZ = 180°
(4k + 5)° + (6k + 10)° + 60° = 180°
10k + 75° = 180°
Therefore,
k = 105/10
k = 10.5
Hence,
The value of k is 10.5.

Bacteria doubles every 10 minutes. If you start with 2 bacteria in a petri dish, how many bacteria will there be after 40 minutes?
Answer: I think the answer is 32 bacteria after 40 minutes.
Step-by-step explanation:
I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

-8 is the real answer
Step-by-step explanation:
Which list gives all the factors of 8? 2, 4, 6, 8 8, 16, 24, 32 1, 3, 5, 7 1, 2, 4, 8
Answer:
{1,1,2,2,4,4,8,8}
Step-by-step explanation:
In Finding The Factor Of A Number You Need To Find A multiplication of Two Numbers That Gives The Product 8.
•So keeping this in mind you can make multiples of numbers which has an outcome of 8. So;
1×8=8 {So 1 is a factor of 8 and note that any number multiplied by 1 is the number itself}
2×4=8{Two multiplied by four is going to give you 8 that's why it's a factor of 8}
3×?=8{There is no number which can be multiplied by 3 which has it's outcome as 8 so 3 isn't a factor}
4×2=8{4 multiplied by 2 is the same as 2 multiplied by 4 so you can see that when you multiply two numbers and it has it's product as 8 those two numbers that you multiplied to get the 8 is a factor of 8}
5×?=8{With the number 5 you can see that there is no number which can be multiplied by 5 which has its outcome as 8 so 5 is not a factor of 8}
6×?=8{With the number 6 you will not get any number which can be multiplied by 6 to give you 8 so 6 isn't a factor of 8}
7×?=8{With the number 7 too you won't get any number to be multiplied by 7 which is going to give you 8 that's why it isn't a factor of 8}
8×1=8{With the number 8 you can clearly see that when 8 is multiplied by 1 the product is 8 so that makes it its factor}
After finding the multiplication of Two Numbers that are going to give you 8, you can conclude that you have found the factors of 8 and note that any number above 8 can't be a factor of 8.
So we can conclude that the Factors of 8 are;

What is the measure of angle 1?
Write the answer without the degree.
Answer: 70
90+20=110
180-110=70
I hope this is good enough:
Answer:
70
Step-by-step explanation:
Everything needs to add up to 180. So you have 90 and 20 you will add them and you’ll get 110. Since you want to find the missing measurement you will subtract 180-110 and you’ll get 70. The missing angle is 70. To check: 90+20+70=180

On Monday he practice for 1 12 1 2 12 1 2 hours, on Tuesday he practiced for 2 14 1 4 14 1 4 hours, and on Wednesday he practiced for 1 12 1 2 12 1 2 hours. How many hours does Cesar need to practice during the rest of the week in order to have his 10 total hours?
Answer: See explanation
Step-by-step explanation:
Your question isn't really clear. Let me help you rephrase it and solve.
Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.
The total hours that Cesar has used in practicing will be:
= 1 1/2 + 2 1/4 + 1 1/2
= 5 1/4
To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:
= 10 - 5 1/4
= 4 3/4 hours.
Cesar needs to practice for 4 3/4 hours more.
Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *
Answer:
Answer: Around 1000 students would buy a school lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a school lunch.
Which number produces an irrational number when added to 0.4?
O A. 0.444...
B. 9
C. 3pi
D. 2/7
Answer: C) 3pi
pi is irrational, and so is 3pi
The expression 3pi+0.4 is overall irrational as well.
If x is irrational and y is rational, then x+y is irrational
This is why choice C is the answer.
The other answer choices are rational values which would make the sum rational, so that's why we can rule them out.
Sandy sold 22 tickets, which was at least 6 more than twice the number of tickets that Teresa sold. This can be represented by this inequality, where t represents the number of tickets Teresa sold.
Which could be a number of tickets that Teresa sold?
17
11
7
14
Answer:
7
Step-by-step explanation:
Let 'x' represent the number of tickets that Teresa sold, and x is integer and x>=0 (you can not sell negative number of tickets)
6 + 2x < 22
x < 8
The range of possible number of tickets that Teresa sold is {0, 1, 2, 3, 4, 5, 6, 7}.
