Identify the equation of direct variation given that y varies directly with x.
y is 15 when x is 11.

Answers

The equation of direct variation given that y varies directly with x.

y is 15 when x is 11 will be [tex]y = \dfrac{15}{11} x[/tex].

What is proportionality?

The proportional relationship between x and y can be written symbolically as

[tex]x \propto y[/tex]

That middle sign is called the sign of proportionality.

Variation: Direct from y to x:

[tex]x \propto y[/tex]

y = 15, x= 11

Write the equation

[tex]x \propto y[/tex]

Express as an equation

[tex]y = kx[/tex]

Where k is the constant of variation

Substitute

y = kx

15 = 11k

Solve for k

k = 15/11

Substitute  in [tex]y = kx[/tex]

[tex]y = \dfrac{15}{11} x[/tex]

Thus, the equation of direct variation given that y varies directly with x.

y is 15 when x is 11 will be [tex]y = \dfrac{15}{11} x[/tex].

MATH!!! find the volume of the pyramid. pleaseee answer correctly and tell me how you got your answer.

Answers

The area of polygons formulas to V=2.56m^2

We have to determine,

The volume of the pyramid.

What is the volume of the pyramid?

The volume of a pyramid is found using the formula,

V = (1/3) Bh

where 'B' is the base area and 'h' is the height of the pyramid.

hight =2.4m

base=1.4+1.8

base=3.2m

V = (1/3) (3.2)(2.4)

V=2.56m^2

As we know the base of a pyramid is any polygon,

we can apply the area of polygons formulas to find 'B.

V=2.56m^2.

Keisha pumped 6 gallons of water into her pool each minute for 48 minutes what was the total change in the amount of water in the pool

Answers

The total change in the amount of water in the pool is 288 gallons.

What is Volume?

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

Here, Rate of water pumped into her pool = 6 gallons / minute.

          Total Duration = 48 minutes

Total amount of water = Rate X Time

                                     = 6 X 48

                                     = 288 gallons

Thus, the total change in the amount of water in the pool is 288 gallons.

Without using the formula, work out the gradient of the graph shown.

Answer: gradient = 2

Reason:

Start at the y intercept (0,4) which is where the red line crosses the y axis.

Then move up 2 units, and to the right 1 unit to arrive at (1, 6) which is another point on this red line.

The motion of "up 2, right 1" means:

rise = 2run = 1gradient = slope = rise/run = 2/1 = 2

Feel free to use any other two points you prefer and you should get the same result. For instance, you could have started at the x intercept (-2,0) and did the "up 2, right 1" motion to arrive at (-1, 2).

Please help ffast and thanks!

Answers

Answer:

  6 h

Step-by-step explanation:

The relation between time, speed, and distance is ...

  time = distance / speed

The total time for the two segments of her ride will be the sum of the times for each of the segments.

__

first 9 miles

  t1 = (9 miles)/(3 mi/h) = 3 h

last 6 miles

After riding 9 miles of the 15-mile distance, Dana had 15 -9 = 6 miles to go.

  t2 = (6 miles)/(2 mi/h) = 3 h

total time

The total time required for the distance of 15 miles is ...

  t1 +t2 = (3 h) +(3 h) = 6 h

It took 6 hours for Dana to cover the distance.

A penny, nickel, and dime are simultaneously flipped. What is the probability that heads are showing on at least 6 cents worth of coins

Answers

Answer:

5/8

Step-by-step explanation:

The number of possible outcomes after flipping 3 coins is $2 \times 2 \times 2 = 8$. If the dime isn't heads, we need both the penny and nickel to be heads. If the dime is heads, the other two could be anything. So there are a total of $1+(2 \times 2)=5$ ways for us to get at least 6 cents. The answer is $\boxed{\dfrac58}.$

Assuming the time changes at a constant rate, the equation for this is linear (so has the equation y=mx +c)

8am = -2

9am = -0.5

10am = 1.0

11am = 2.5

12pm = 4

m = change in each value or the slope , for this it is m=1.5

c = the y intercept, we find this by: when x=8 y must = 1.5 , which it isn't , y has to = -2 . So c = -3.5

The equation then is: y= 1.5*x - 3.5

The gradient/slope/m value is 1.5. The answer is 1.5

Part A: The amount of ice cream increases as the temperature increases. Part B: the slope is 2 and the y-intercept will be 5.

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

Part A: The relationship between the temperature of the city and the number of ice cream cones sold.

From the graph, the dots on the graph increase in the up-right direction.

Thus, The amount of ice cream increases as the temperature increases.

Part B: The line of best fit

First, if we draw a line through the points

we select any 2 points on the line:

( p,q) and (x,y) as (15, 35) and (0, 5).

The slope (m) is:

[tex]m = \dfrac{y-q}{x-p}[/tex]

[tex]m = \dfrac{5 - 35}{0-15}\\\\m = 2[/tex]

So, the line of best fit is:

y = mx + c

y = 2(x - 0) + 5

y = 2x + 5

The y-intercept will be when x = 0

y = 2x + 5

y = 0 + 5

y = 5

Thus, the slope is 2 and the y-intercept will be 5.
