What is the slope of a line that goes through the points (3,7) and (8, 11)

Answers

Answer:

The answer is

[tex] \huge \frac{4}{5} \\ [/tex]

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]

From the question we have

[tex]m = \frac{11 - 7}{8 - 3} = \frac{4}{5} \\ [/tex]

We have the final answer as

[tex] \frac{4}{5} \\ [/tex]

A bucket of water is 1/2 full but it still has 3 4/6 gallons of water in it how much water do you need to fill the bucket

Answers

Answer:

7 1/3 gallons

Step-by-step explanation:

If the bucket is half full and still has half to go, you double the current contents of the bucket. 3 4/6 times 2 is equal to 7 2/6 gallons which simplifies to 7 1/3 gallons.

I don't fully understand your question though, if the question is asking how much MORE water is needed to fill the bucket, it's 3 2/3 gallons. If it's asking how much water in TOTAL it would take to fill the bucket completely, it's 7 1/3 gallons.

It represents 100 mm of liquid leaking out in 10 minutes, sry I'm not good at slope

Answer:

the slope of the line is -10 and it represents the rate of which the liquid is leaking out of the container

Step-by-step explanation:

find any 2 points on the line. i chose (10,800) and (20,700)

the formula for slope is m = y2-y1 divided by x2-x1

plug the numbers in, then solve and it should be

m = 800-700 / 10 - 20

m = 100 / -10

m = -10

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of girls in the class be = G

Now , let the total number of boys in the class be = B

The total number of students in the class = S

The value of S = 30 students

The percentage of boys in the class = 40 %

So , the equation will be

The number of boys in the class = percentage of boys in the class x total number of students in the class

Substituting the values in the equation , we get

The number of boys in the class = ( 40/100 ) x 30

The number of boys in the class = 30 x 0.4

The number of boys in the class = 12 boys

So , the number of girls in the class = total number of students in the class - number of boys in the class

Substituting the values in the equation , we get

The number of girls in the class = 30 - 12

The number of girls in the class = 18 girls

Therefore , the value of G is 18 girls

Hence , The number of girls in the class is 60% or 18 girls
