Answer:

18 girls

Step-by-step explanation:

Since girls have one more unit of ratio than boys, and there are 6 more girls in class,

1 unit = 6 people

2 units = 12 people

3 units = 18 people

Therefore, plug it back in, there are 12 boys and 18 girls

Solve the equation 3x = 9.5 Show and justify each step you take to solve the equation . 3x = 9 Write the equation 9 Divide each

zimovet [89]

Answer:

3x=9.5, you would divide 3 on each side to get x by itself, so (3x)/3=9.5/3, which would lead to be x=9.5/3 or x= 3 and 1/6th, 3 + 1/6

Find the distance between the two points rounding to the nearest tenth (if necessary).

Genrish500 [490]

Answer:

13 units

Step-by-step explanation:

(-1,5) and (4, -7)

To find the distance of two points, we use the distance formula:

$d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }$

Let's plug in what we know.

$d = \sqrt{(4 - (-1))^2 + (-7 - 5)^2 }$

Evaluate the double negative.

$d = \sqrt{(4 +1))^2 + (-7 - 5)^2 }$

Evaluate the parentheses.

$d = \sqrt{(5)^2 + (-12)^2 }$

Evaluate the exponents.

$d = \sqrt{(25) + (144) }$

Add.

$d = \sqrt{(169) }$

Evaluate the square root.

$d = 13$

13 units

Hope this helps!

You are standing on a small fire tower 50 feet from a tree. You notice a squirrel in the tree. You measure the angle of depressi

irina [24]

Answer:

44.81 feet

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ACD

Find the length side AC (height of the small fire tower)

$tan(52^o)=\frac{AC}{50}$ ---> by TOA (opposite side divided by the adjacent side)

Solve for AC

$AC=tan(52^o){50}$

$AC=64\ ft$

step 2

In the right triangle ABE

Find the length side AB

$tan(21^o)=\frac{AB}{50}$ ---> by TOA (opposite side divided by the adjacent side)

solve for AB

$AB=tan(21^o){50}$

$AB=19.19\ ft$

step 3

How many feet off the ground is the squirrel?

Subtract the length side segment AB from the length side segment AC

$64-19.19=44.81\ ft$

the amount of food a dog should eat depends on the weight of the dog. 1. identify the independent and dependent variables in thi

fomenos

Here, we are required to identify the dependent and independent variables, the dependency relationship in the situation.

The independent and dependent variables are the weight of the dog and the amount of food it should respectively.
The dependency relationship is thus; The amount of food a dog should eat is a function of the weight of the dog
The dependency relationship using the function notation is; f(x) = {function of x}.

The independent variable in this situation is the weight of the dog while the amount of food the dog should eat is the dependent variable. The above is evident from the statement; The amount of food a dog should eat depends on the weight of the dog.

According to the premise given in the question, it is evident that the dependency relationship is;. The amount of food a dog should eat is a function of the weight of the dog

The dependency relationship can be written mathematically using the function notation as;. f(x) = {function of x}.
