Answer: Direct means when x goes up y also goes up, inverse means when x goes up, y goes down and vice versa.

Answer:

Step-by-step explanation:

The answer is that with direct variation, the value and the quantity changes and goes according, either lower or higher, but with inverse variation, the value can go higher, and the quantity can go lower, and the quantity can go higher, but the value can be lower.

Answer: Either use a calculator or do mental math/ practice more often.

Answer:

The land that is covered with an irrigation arm of 370 ft is  [tex]430,084\ ft^2[/tex]

Step-by-step explanation:

Area of the circle

Being r the radius of a circle, its area can be calculated as follows:

[tex]A=\pi\cdot r^2[/tex]

The irrigation arm acts as the radius of the irrigation circle, thus r=370 ft. The land covered is the area under the irrigation arm, thus:

[tex]A=\pi\cdot 370^2[/tex]

[tex]A=430,084\ ft^2[/tex]

The land that is covered with an irrigation arm of 370 ft is  [tex]430,084\ ft^2[/tex]

The solution of the equation when m = 2 and 11 = -3 will be - 52.

For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs,

So solution to a system is the intersection of all its equation at single point(as we need common point, which is going to be intersection of course)(this can be one or many, or sometimes none)

We have been given; 10m - 8n^2

(if m = 2 and 11 = -3)

If we plug in the variable

the equation is 20 - 8(-3)^2

Now, do the exponent

So, 20 - 8^9,

Then multiply

20-72 = -52.

Therefore, the solution of the equation when m = 2 and 11 = -3 will be - 52.

Answer:

The second smoothie recipe has more strawberries compared to other ingredients

Step-by-step explanation:

Recipe 1:

2 cups of strawberries : 7 cups of other ingredients

= 2/7

= 0.29

Recipe 2:

3 cups of strawberries : 9 cups of other ingredients.

= 3/9

= 1/3

= 0.33

The second smoothie recipe has more strawberries compared to other ingredients

Answer:

Kindly check explanation

Step-by-step explanation:

Given that there were five rummers in the team;

Each runner finished one after the other

Total. Points scored =. 55

Let the positions of each runner be :

1sr runner = p

2nd runner =.p + 1

3rd runner =.p + 2

4th runner =.p + 3

5th runner =.p + 4

(1st + 2nd + 3rd + 4th +. 5th) runner = 55

(p + p + 1 + p + 2 + p + 3 + p + 4) = 55

5p + 10 = 55

5p = 55 - 10

5p = 45

p = 9

Hence,

1st runner = 9th

2nd runner = 9 + 1 = 10th

3rd runner = 9 + 2 = 11th

4th runner = 9 + 3 = 12th

5th runner = 9+ 4 = 13th

Let, price of fudge and gum is x and y respectively.

Converting given statements into mathematical equation.

We get :

5x + 3y = 5.70  ....1)

2x + 10y = 3.60 ....2)

Solving equation 1 and 2, we get :

x = $1.05 .

y = $0.15 .

Price of buying 20 pieces of fudge and 20 pieces of bubble gum is :

P = 20( 1.05 ) + 20( 0.15 )

P = $24

Hence, this is the required solution.

Answer:

set two equation of line y=ax+b and y=cx+d

when these two lines are perpendicular to each other, then a*c=(-1)

x-2y=2

=>x-2=2y

=>(1/2)x-1=y

set the answer is y=ax+b

we can know that a/(1/2)=(-1)

=>a=-2

bring a=-2 and(7,-7) in y=ax+b

-7=(-2)*7+b

=>b=7

the answer is y=-2x+7

Answer:

c

Step-by-step explanation:

its really simple it's c

======================================================

Work Shown:

c = number of correct answers

w = number of wrong answers

n = number of questions not attempted

2c = points you get from all the correct answers

-1w = points you get from all the wrong answers

0n = points you get from all the questions attempted

2c-1w+0n = 2c-w = total number of points

In this case, she got 8 correct answers and 2 wrong answers. So c = 8 and w = 2 which leads to

2c-w = 2*8-2 = 16-2 = 14

Her total score is 14.

Step-by-step explanation:

-2(x + 1/4) + 1 = 5

-2x - 1/2 + 1 = 5

-2x + 1/2 = 5

-2x = 5 - 1/2

-2x = 4 1/2

-x = 2 1/4

x = -2 1/4

Answer:

Maggie is 13

Step-by-step explanation:

Honestly, I just kept trying ages starting from 10 because I knew it wasn't going to be less than that. Then I did whatever age, in this case 13, and multiply it by  4. Then minus 11 from that number. Then take that end number and add it to the beginning number(maggies age) and you should get 54.

Math Equation Explanation:

13*4 = 52                           (Maggies Age) x 4

52-11= 41                            The question stated that Maggie's brother was 11                                             -------------------------------------years younger than her age times 4.

41 + 13 =54                          The sum of both their ages.
