En una piscina hay 1500 litros y el desagüe bota en el despiche medio litro por minuto. La función que describe la cantidad de litros (lt) que habrá en la piscina a las x horas después de abrir el despiche del desagüe es

Answer:

We know that 8 teams of students shared 47 pizzas.

The only thing we can assume is that the 47 pizzas where divided evenly between the teams, so the number of pizzas that each team gets is equal to the quotient between 47 and 8, or:

47/8 = 5.875

But this is not a whole number, and this happens because 47 is not a multiple of 8.

Then we can do:

47 = 40 + 7

And 40 is a multiple of 8.

40/8 = 5

Then each team got 5 whole pizzas, and there are 7 pizzas left.

Now, we can assume that each pizza has 8 slices.

Then there are left 7*8 = 56 slices.

And when we divide those by the number of teams, we have:

56 /8 = 7

So each team gets 7 slices from the remainder pizzas.

Then we can conclude that each team gets 5 whole pizzas and 7 slices.

Answer:

Step-by-step explanation:

9x - 5 = 58

9x = 63

x = 7

<2 = 32°

7y + 27 + 58 + 32 = 180

7y + 117 = 180

7y = 63

y = 9

for <1: x + 58 = 180

       x = 122°

Answer:

x=31/14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−4x+1=−9x−16+9x+16

−4x+1=−9x+−16+9x+16

−4x+1=(−9x+9x)+(−16+16)(Combine Like Terms)

−4x+1=0

−4x+1=0

Step 2: Subtract 1 from both sides.

−4x+1−1=0−1

−4x=−1

Step 3: Divide both sides by -4.

−4x−4=−1/-4

x=1/4

True

Step-by-step explanation:

The above statement is true because a mixture is a combination of two or more substances. and this is done physically ( not chemically as seen in compounds) which in turn gives rise to the varying physical and chemical property that a mixture possess , while a pure substance is inseparable while maintaining a constant physical and chemical property as well

Answer:

(4.91, 3.5)

Step-by-step explanation:

6x+21y=103

+

-6x+23y=51

=

44y=154

y=3.5

6x+21(3.5)=103

6x+73.5=103

6x=29.5

x=4.91

(4.91, 3.5)

Answer:

The answer is (4,6) because you would have to eliminate the -6 and 6 to get the y which would be 24y and then divide 154/24 which is roughly 6 and then put that in to get x which is roughly 4

you can also use elimiation for y as well

Answer:

17 feet

Step-by-step explanation:

Here, we want to calculate the vertical distance between Carl’s and Cameron’s feet

Since Carl is at the base of the pool, the distance between the water surface and the base of the pool will be 15 feet

We are also told they Cameron is on a diving platform 2 feet above;

So the distance between the two of them will be ;

15 feet + 2 feet = 17 feet

Given

[tex]x = -7.5[/tex]

[tex]Expression: -3.8x + 6[/tex]

Required

Determine Gaira mistake

When Gaira solved the expression, she solved as:

[tex]-3.8x + 6x[/tex]

Giving her

[tex]-3.8x * -7.5 + 6 * -7.5[/tex]

This is incorrect as the correct expression is

[tex]-3.8x + 6[/tex]

and it is solved as follows:

Substitute -7.5 for x in -3.8x + 6

[tex]-3.8x + 6[/tex]

[tex]-3.8 * -7.5 + 6[/tex]

[tex]28.5 + 6[/tex]

[tex]34.5[/tex]

34.5 is the correct solution

Answer:

Gaira made a mistake when substituting the value –7.5 in for x. She multiplied both terms of the expression by –7.5 when she should have only multiplied –3.8 by –7.5. The correct answer is 34.5.

Answer:

The area covered by the wiper blade is 35 square inches

Step-by-step explanation:

Here, we want to calculate the area covered by the blade of the wiper

Mathematically, this is simply the area of the sector formed by the wiper on the screen

This can be calculated as follows;

theta/360 * pi * r^2

From the question theta = 50 degrees

r = the length of the wiper = 9 inches

So the area is;

50/360 * 22/7 * 9^2 = 35.35714285714286

This is closest to 35 square inches

Question:

Find 4 possible solutions in the context of the problem.

The 4 possible solutions in the context of the problem are (0, 8), (3, 6), (6, 3), and (9, 2)

Given the equation that models the situation expressed as:

4x + 6y = 48

We are to find 4 possible solutions for x and y. Note that the values of x and y must be integers.

If there are no cars i.e. at when x = 0

4(0) + 6y = 48

0 + 6y = 48

6y = 48

y = 48/6

y = 8

One of the solution is (0, 8)

If there are 3 cars, i.e. at when x = 0

4(3) + 6y = 48

12 + 6y = 48

6y = 48 - 12

y = 36/6

y = 6

The second solution will be (3, 6)

If there are 6 cars, i.e. at when x = 6

4(6) + 6y = 48

24 + 6y = 48

6y = 48 - 24

y = 24/6

y = 4

The third solution will be (6, 3)

If there are 9 cars, i.e. at when x = 9

4(9) + 6y = 48

36 + 6y = 48

6y = 48 - 36

y = 12/6

y = 2

The fourth solution will be (9, 2)

Hence the 4 possible solutions in the context of the problem are (0, 8), (3, 6), (6, 3), and (9, 2)
