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 100% discount.

A 2-for-1 deal means you pay the price of one and you get another one free. One as a percentage is 100%

Answer:

54%

Step-by-step explanation:

if you take 18 and divide it by 33 you would get 54

The 83.33 percent increase in Hannah's hair length.

A percentage is a number or ratio expressed as a fraction of 100.

Hannah's hair was 18 inches long

After three years,

it was 33 inches long

[tex]Difference\ (increase\ in\ length) = 33-18=15\ inches[/tex]

[tex]percent\ increase = \dfrac{Increase}{Original\ Number}\times100=\dfrac{15}{18}\times100=83.3333\\\\percent\ increase = 83.33 (nearest\ hundredth)[/tex]

Hence 83.33 % increase in Hannah's hair length after three years.

(48/2)-4^2 +2*2=12

I hope you have a nice day!

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.

Inequalities help us to compare two unequal expressions. The inequality that represents the domain of this situation is 0<m<30.

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.

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.

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

Answer:

Step-by-step explanation:

For problem 10:

1. AE/ED=AC/CB (Since triangle ABC is similar to triangle ADE, we can determine that the ratio of AE to ED is equal to the ratio of AC to CB)

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)

2. AG/(AG+GB)=AE/(AE+ED) (Rewrite sides as the some of their parts)

3. 14/(14+7)=18/(18+x) (Substitute given values)

4. x=9 (Solve for x)

Answer:

Step-by-step explanation:

7x+9=2x+39

7x+9-9=2x+39-9

7x=2x+30

7x-2x=2x+30-2x

5x=30

5x/5=x

30/5=6

x=6

Answer:

X=6

Step-by-step explanation:

7x+9=2x+39

First, subtract 9 from both sides like this

7x+9 -9 =2x+39-9

equaling 7x=2x+30

Then, subtract 2 from both sides like this

7x - 2=2x -2+30

equaling 5x=30

Lastly you divide 5 from both sides like this

5x / 5 = 30 / 5

equaling x=6
