Answer:
so the exterior angle 152 is made from the interior angle being subtracted from 180. we can also subtract 152 from 180 to find the interior angle. 180-152=28 the inside of a triangle is a total of 180 degrees so 110+28=138 180-138=42 degrees. 42 degrees is the final interior angle and the missing and the missing exterior angle is congruent to the 42 degree angle. So the missing exterior angle is 42 degrees

Which inequality represents the following statement?
"A number increased by 4 is at most 15."
Answers
Answer:
x + 4 ⩽ 15
Step-by-step explanation:
Let
The number = x
At least in inequality is ⩾ (greater than or equal to sign)
At most in inequality is ⩽ ( less than or equal to sign)
A number increased by 4 is at most 15.
x + 4 ⩽ 15
The inequality that represent the statement is x + 4 ⩽ 15
x + 4 ⩽ 15
x ⩽ 15 - 4
x ⩽ 11

63 is the sum of all their ages, meaning that this is their ages added altogether, eliminating A and D as answer choices since those show multiplication instead of addition. Next, the problem states that the three consecutive integers are odd. This statement eliminates B as an answer choice since it’s using three consecutive even integers. This leaves C as your final answer.

The population of a certain town was 50,000.In a year,male population
was increased by 5% and female population was increased by 3%. Now
the population beame 52020. Then what was the number of males and
females in the previous year?
olution:- Let the number of males in previous year be x,number of females
Answers
Answer: Male population = 26,000
Female population = 24,000
Step-by-step explanation: Male population = X
Female population = Y
x+y=50,000
y=50,000-x-(1st equation)
Again (x+x X 5%) + (y+y X 3%) = 52,020
-> x+5x/100 + y+3y/100 = 52020
-> 100x+5x+100y+3y =52020
________________
100
-> 105x+103y = 52020-( 2nd Equation)
Putting Eq 1 into 2 ,
105x+103 ( 50,000-x)= 52,020
-> 105x + 5,150,000-103x = 52,020
->2x = 52,020-5,150,000
->2x = 52,000
x = 26,000 (Male population)
y = 50,000-26,000
= 24,000 (Female population)

basically, 8 can go into 24 exactly but 15 and 5 can not go into 15 perfectly neither can 24. 24/3 is 8 and 15/3 is 5

Suppose that the number of bacteria in a certain population increases according to an exponential growth model, with a growth rate of 19% per hour. Suppose also that a sample culture of 2300 bacteria is obtained from this population. Find the size of the sample after five hours. Round your answer to the nearest integer.
Answers
Answer: 5489
Step-by-step explanation:
Given the following :
Growth rate (r) = 19% per hour
Sample culture in population = 2300
Size of sample after 5 hours =?
Using the exponential relation:
P = Po * r^t
P = population after 5 hours
Po = Initial sample population
t = time
P = 2300 * (1 +19%)^t
P = 2300 ×(1 + 0.19) ^5
P = 2300 * 1.19^5
P = 2300 * 2.3863536599
P = 5488.61341777
P = 5489 (nearest integer)

Answers
Answer:
Step-by-step explanation:
∠A and ∠B are vertical => ∠A=∠B
20x+10=30x-10
20x-30x= -10-10
-10x= -20
x= -20 / -10 = 20 / 10 = 2
x=2
Good luck!
Answer:
2
Step-by-step explanation:
Ok remember this because its going to appear alot in geometry. Vertical angles are ALWAYS congruent and congruent means when two things are equal/ are the same.
If angle a and b are vertical angles what does that mean?
they are CONGRUENT!
you know A = 20x+ 10 and B= 30x-10
so you can write it as
20x+10 = 30x-10
because Angle A and B equal each other
then get the variable by itself so subtract -20x on both sides
10 = 10x-10
then add 10 to both sides which is
20 = 10x
and divide 10 on both side and 20 divided by 10 is 2
so 2 =x
which is the same as x =2

A baseball team is having an end of the year party and the coach wants to purchase gloves and baseballs for the team. Gloves are sold in cases of 8 and baseballs are sold in cases of 12. The coach wants to buy the exact same number of gloves as baseballs.What is the least number of gloves and baseballs he would have to purchase to have the same number of each?
Answers
Answer: 24 is the least number of gloves and baseball need to purchase .
Step-by-step explanation:
Given: Gloves are sold in cases of 8 and baseballs are sold in cases of 12.
To get the exact same number of gloves as baseballs, the least number of gloves and baseball need to purchase = L.C. M. (8,12)
[L.C.M.= Least common multiple]
Since 8 = 2 x 2 x2
12 = 2 x 2 x 3
So, L.C. M. (8,12) = 2 x 2 x 2x 3 = 24
Hence, the least number of gloves and baseball need to purchase = 24
