Evaluate the expression when a=14 and b=6.

-8ab=__

Divide 24 by 40%

24 / 0.40 = 60

The answer is 60

Using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).

Percentage is simply number or ratio expressed as a fraction of 100.

The perecent equation is expressed as;

Percentage = ( Part / Whole ) × 100%

Given the data in the question;

We determine the number, we substitute our given values into the expression above.

Percentage = ( Part / Whole ) × 100%

40% = ( 24 / Whole ) × 100%

40/100 = ( 24 / Whole ) × 100/100

40/100 = 24 / Whole

We cross multiply

40 × Whole = 24 × 100

40 × Whole = 2400

Whole = 2400 / 40

Whole = 60

Therefore, using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).

Answer:

y= 10/3x + 20

Step-by-step explanation:

the slope is 10/3 because from one point to another (on the line) it moves up 10 (from 20 to 30) and to the right 3 (from 0 to 3)

the y intercept is 20 because when x = 0, y = 20 which we can see on the graph

Answer:

y=10/3x +20

Answer:

9π

Step-by-step explanation:

What we need  to do here is convert this equation into a standard circle equation;

x^2+y^2 + 3 = -4y + 6x-1,

x^2+y^2+4y-6x+1 = 0,

x^2-6x+(-3)^2 + y^2+4y+(2)^2  = 3^2

(x-3)^2 + (y+2)^2 = 3^2,

so we have a circle with a radius of 3, and hence the area of our region is π(3)^2 = 9π. correct!

Answer:

Look below :)

Step-by-step explanation:

1. To find the slope of a line, we can use this expression: [tex]\frac{y2 - y1}{x2 - x1}[/tex]

In order to use that expression, we need to use two points. The graph given only provides you with two complete points, so we'll use those.

(4, 4) = (x1, y1)  (12, 20) = (x2, y2)

Now we can input the values into the expression:

[tex]\frac{y2 - y1}{x2 - x1}[/tex] = [tex]\frac{20 - 4}{12 - 4}[/tex]

Let's solve for the slope:

20 - 4 = 16

12 - 4 = 8

[tex]\frac{16}{8}[/tex]

To simplify 16/8 divide both the numerator and the denominator by 8:

16/8 = 2

8 = 1

You get 2/1 or just 2.

The slope of the line is 2.

2. To make an equation for the line, we'll use slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. We already know the value of the slope is 2, so now we need to find the y-intercept. We can find the y-intercept using a given point and the slope. In this example, I'll use the point (4, 4). Let's input the values into the equation:

y = mx + b

4 = 2(4) + b

Now let's solve for b:

4 = 8 + b

Subtract 8 from both sides to isolate the b:

4 - 8 = 8 - 8 + b

-4 = b

The y-intercept of the equation is -4.

Now that we know the values for the slope and y-intercept, we can write the equation:

y = 2x - 4

3. To find the values of a and b, we can use the equation we made in the previous question.

First we'll find a:

The point we are given is (a, 16). We know the y-value is 16, so we can put that into our equation. We can also replace x with a:

y = 2x - 4

16 = 2a - 4

Now we can solve for a:

First, add 4 to both sides to isolate the 2a:

16 + 4 = 2a - 4 + 4

20 = 2a

Then divide both sides by 2 to isolate a:

20/2 = 2a/2

10 = a

The value of a is 10.

Now let's find b:

This is similar to finding a. The point we are given is (8, b). We know the value of x is 8, and we can replace y with b in the equation:

y = 2x - 4

b = 2(8) - 4

Let's solve:

b = 2(8) - 4

b = 16 - 4

b = 12

The value of b is 12.

4. Finally, to find the y- coordinate when x=0, all we have to do is input 0 in for x in the equation and then solve for y:

y = 2x - 4

y = 2(0) - 4

y = 0 - 4

y = -4

When x = 0, y = -4.

The answer for what the y-coordinate is when x = 0 will always be the value of the y-intercept.

Answer:

240

Step-by-step explanation:

20% of the students like rock and 40% like hip-hop. That means that 60% of the 360 students would be expected to choose one of the two. Because you don't know the other 10%, you would assume that they would have the same ratio of students who like the country to those who like rock and hip-hop. 60 is 2/3 of 90, so you would expect 2/3 of the students to like hip-hop or rock. 2/3 of 360 is 240.

and 40 percent

Step-by-step explanation:

Well it’s 12 to 30 so just put a fraction bar

and 12 divided by 30 is .4

Answer:

The answers are 12/30 and 10%

Step-by-step explanation:

It's 40% because the ratio of males to total students is 12 to 30, or 12:30, which is equal to 12/30.

The other answer is 10% because the ratio of males to total students is 3 to 30, or 3:30, which is equal to 1/10. Then you would do 100 divided by 10 which would give you 10 so it's 10%.

Answer:

im only doing this for the points sorry :/

Step-by-step explanation:

Answer:

y = 4x + 3

Step-by-step explanation:

In miles per hour, 4/3 speed represents the flow of water in the river, and its calculation can be defined as follows:

Distance = [tex]\frac{1}{3}[/tex] miles

Time= [tex]\frac{1}{4}[/tex] hours

speed=?

Speed Definition:

An object's speed is indeed the pace at which it moves along a path in time, whereas its velocity is the rate and direction of travel.

The formula for calculating the speed:

[tex]\to[/tex] speed =[tex]\bold{\frac{Distance}{time}}[/tex]

               [tex]=\frac{\frac{1}{3}}{\frac{1}{4}}\\\\={\frac{1}{3} \times \frac{4}{1}}\\\\={\frac{4}{3}}\\\\[/tex]

Therefore, the calculated speed of water flow is [tex]\frac{4}{3}[/tex] miles per hour.

Answer:

5 muffins would be $10.75

Step-by-step explanation:

I you want me to explain just ask.

Answer: For the first question, m = 1.5 and y-intercept = 5, so your equation for the first one should be, y = 1.5x + 5.

And for the second question, m = -1.75 and y-intercept = 4, so your equation for the second one should be, y = -1.75x + 4.

Step-by-step explanation: For the 1st one, subtract 3x to get -2y = -3x - 10, then divide by -2 to get y = 1.5x + 5.

For the 2nd one, subtract 7x to get 4y = -7x + 16, then divide by 4 to get y = -1.75x + 4.

Hope this helps you! :)
