Elena has a washing machine with a 20 gallon capacity. She always uses a 20 gram measure of soap for every 10 gallons of water.

One day she tells her son Francisco to fill the washing machine halfway with water, to add the soap and dissolve it well, but Francisco is wrong and adds 60 grams of soap to the water. When Elena realizes the mistake, she thinks of adding pure water to the tank at a rate of 2 gallons per minute and simultaneously opening the drain so that the volume of water in the washing machine remains constant. Assuming the liquid remains uniformly mixed, for how long should Elena add water to correct the error?

Answer:

For \[20\] minutes Elena add water to correct the error.

Step-by-step explanation:

The capacity of the washing machine is \[20\] gallons.

She uses \[20\] gram soap for \[10\] gallon of water

Her son by mistake dissolved \[60\] grams of soap to \[10\] gallons of water.

\[60\]-gram soap is right for \[30\] gallons of water, thus \[20\] gallon of water must be added more.

She pore water \[2\] gallons per minute thus, \[20\] gallons of water will take\[10\]minutes.

A fishing rod and reel cost a total of $110. The reel cost $100 more than the rod. What is the final cost of
KIM [24]

Answer:

Hi there!

Your answer is:

The rod is equal to $5

The reel is equal to $105

Step-by-step explanation:

Rod= R

Reel= E

Rod = R

E= 100+r

(100+R)+R= 110

100+ 2R= 110

-100

2R = 10

/2

R= 5

E= 100+5

The rod is equal to $5

The reel is equal to $105

box A has 4 marbles.box A has 5% of the marbles.what is the total amount of marbles in all four boxes
laila [671]
Box A is 4. 4 is 5% of the total boxes.
5% = 1/20, so multiply whatever number that's 5% of the total by 20 to get the total.
4 x 20 = 80.
There are 80 marbles total.
Hope this helps!

A diver dives from the board at a local swimming pool. Her height, y, in metres, above the water in terms of her horizontal dist
Aneli [31]

Answer:

4 meters

Step-by-step explanation:

Given a quadratic equation in which the coefficient of x^2 is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.

Since the divers height, y is modeled by the equation

y= -x^2 + 2x + 3

Step 1: Determine the equation of symmetry

In the equation above, a=-1, b=2, c=3

Equation of symmetry, x=-\dfrac{b}{2a}

x=-\dfrac{2}{2*-1}\\x=1

Step 2: Find the value of y at the point of symmetry

That is, we substitute x obtained above into the y and solve.

y(1)= -1^2 + 2(1) + 3=-1+2+3=4m

The maximum height of the diver is therefore 4 meters.
