The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle.
(2x+18)°
55°
(4x+11)°
Answers
Answer:
(2x+18) degrees
Step-by-step explanation:
A triangle is a total of 180 degrees, so you would do:
(2x+18)+55+(4x+11)=180
(2x+4x)+(18+55+11)=180 <- take out parentheses and add like terms
6x+84=180 <- subtract 84 from both sides of the equation
6x=96 <- divide 6 from each side
x=16
Now that you know what x is you would plug it into each of the angles
Angle 1: 2x+18 --> 2(16)+18= 32+18= 50
Angle 2: 55
Angle 3: 4x+11 --> 4(16)+18= 64+18= 82
Then out of these three angles of the triangle, angle 1 (2x+18) would be the smallest.

h + 86.43 = 531.79
h = ___________
Answers
because you bring the 86.43 over to the 531.79. which would make 86.43 a negative number. so you subtract 531.79 by 86.43
Answer:
h=445.36
Step-by-step explanation:
Subtract both sides by 86.46
531.79 - 86.43 = 445.36
Check answer by plugging it back in
445.36 + 86.43 = 531.79

Answer:
Point A is located at (8,6)
Step-by-step explanation:
As I said in the last answer I did for u, (8,6) basically means x is 8 and y is 6. If you see A, A is located on 8 for x and 6 for y. the others are incorrect such as B because B is on the 8 for x but the y is on 8. hope this helps '∆'
Answer:
A
Step-by-step explanation:
A is the answer because you look down at 8 and count up 6 times but dont count the 8 and your answer would be A ( A, 8 ) is on 6 .

Dr. Wong has a table of data in her veterinary office that shows the average lifespans and weights of several popular dog breeds. Alfonso made a scatterplot of these data for a math project.
Answer the questions to make predictions about the lifespan of a specific breed of dog.
1. Describe the association shown by this scatterplot.
2. Alfonso is thinking of getting a bloodhound. Bloodhounds usually weigh about 90 pounds. Based on the data, estimate for the lifespan of a bloodhound. Explain how you made your estimate.
3. Alfonso's friend Dani tells Alfonso that her bloodhound, Ol' Sniffy, lived to be 14.
Based on what you know, do you think this was because:
1. Alfonso didn't use a good estimation method,
2. Dani doesn't remember Ol' Sniffy's age correctly, or,
3. Ol' Sniffy lived an unusually long time?
Justify your answer.
Answers
Answer:
1. The heavier the dogs are, the shorter lifespan they have.
2. The lifespan of a bloodhound is on average 10 years long
3. Number 2
Step-by-step explanation:
#1 explination: Since its obvious that the graph angles downwards as it goes towards the left, and because as you go to the left you get heavier dogs, put 2 and 2 together and you get my answer.
#2 explination: We see 3 dots around 90 pounds, one that lives 11 years, and 2 that live 10 years. Since we need to be accurate, we need to find the average of 10, 11, and 10. (10+10+11)/3=10.33. Now we round to 10, so 10 is our answer.
#3 explination: Since there is a bloodhound that lives to be 14, we have two answers, 2 or 3. 1 doesn't work since if Alfonso doesn't have good estimation, the first two questions wouldn't matter *the more you know*. Since we see no unusual pattern between any of the three dots I mentioned earlier, Dani must of forgotten her dog's age (probably because of that dog years thing.)

A tank can hold a maximum of 400 gallons of water. The volume of water when pumping water into the tank can be determined by the function f (m) = 12.5m + 25 where m is the number of minutes that the pump is running and f(m) is the volume of gallons of water in the tank. If the tank must maintain a minimum of 25 gallons of water, which inequality represents the domain of this situation?
(Hint: The variable f(m) is like "y" and m is like "x")
0 < m < 400
30 < m < 400
25 < m < 400
0 < m < 30
Answers
Inequalities help us to compare two unequal expressions. The inequality that represents the domain of this situation is 0<m<30.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that the volume of the tank should be between 400 gallons of water to 25 gallons of water. While the function of the volume of the water is given as,
f(m) = 12.5m + 25,
Now to know the value of m for which the volume of water in the tank is 400 gallons.
[tex]f(m) = 12.5m + 25\\\\400=12.5+25\\\\375=12.5m\\\\m = 30[/tex]
Also, the value of m for which the volume of the water in the tank is 25 gallons is,
[tex]f(m) = 12.5m + 25\\\\25=12.5+25\\\\0=12.5m\\\\m = 0[/tex]
Hence, the inequality that represents the domain of this situation is 0<m<30.

2. AE/ED=(AE+EC)/CB (Rewrite AC as the sum of the lengths forming it; This is sometimes referred to as the Partition Postulate)
3. 9/x=(9+6)/10 (Substitute the given values into this equation)
4. x=6 (Use algebra to solve for x)
For problem 11:
1. AG/AB=AE/AD (Use the same strategy as step one in problem 10, since the rectangles are similar we can create this equation)

Write an equation for the relationship shown in the table.
Answers
Answer:
(0.3/1)x-1.7
Step-by-step explanation:
I used the format mx+b
m= slope
x= x value (usually stays as x when you write an equation and replace it with the x value when solving)
b= y-intercept (in this case when p is zero what is the q value)
y-intercept = -1.7 (in this equation found from the table)
slope= 0.3/1 (the rate it the numbers increase at. q is changing +0.3 each time and p is changing by 1. p (or the x value) goes on top of q (or the y value)) (I found the missing information in between 2 and 5)
hence you have (0.3/1)x-1.7

One market sells a 3-kilogram bag of tortillas for 45 pesos, and the second market sells 2 kilograms of tortillas for 22 pesos.
Which unit price is lower? / Would I subtract 2 kilo from 22 pesos?
Answers
Answer:
The second market is cheaper
Step-by-step explanation:
For the first market:
If the 3Kg = 45 pesos
then 1Kg = 15 pesos because you divide it by 3
In the same way for the second market:
2Kg = 22pesos
so 1Kg is 11 pesos as you divide it by 2.
Therefore the second market is cheaper as the unit price is lower.
