Answer:

Ben will drink 5\frac{1}{4} liters of tea in one hour.

Step-by-step explanation:

Ben drinks 3\frac{1}{2} or \frac{7}{2} liters of tea in every \frac{2}{3} of an hour.

Here \frac{2}{3} of an hour can be represented in minutes as

\frac{2}{3}\times 60 minutes = 40 minutes.

Now we will apply unitary method to solve this question.

∵ Ben drinks amount of tea in 40 minutes = \frac{7}{2} liters

∴ Ben will drink tea in 1 minute = \frac{7}{2\times 40}

∴ Ben will drink the amount of tea in 60 minutes = \frac{7\times 60}{2\times 40}

                                                                                 = \frac{420}{80}

                                                                                 = \frac{21}{4} liters

                                                                                 = 5\frac{1}{4} liters

Therefore, in one hour Ben will drink 5\frac{1}{4} liters of tea.

Divide 3 1/2 by 2/3. 3 1/2 = 7/2 as an improper fraction, so we have 7/2 ÷ 2/3 = 7/2 * 3/2 = 21/4 = 5 1/4 L

I'm not the best at writing, but I can try. so here's an idea:you can have as your scenario something like "On a vase shaped like a rectangular prism is a flower. Knowing that the stem of the flower is the diagonal of the prism, the diagonal of the base is 18 and the sinus of the angle between the stem and the diagonal(of the base) is 4/5, find the stem's length and the height of the vase"

Answer:

y = 45 / 2x + 50

Step-by-step explanation:

The best equation for the line of the best fit would be y = 45 / 2x + 50.

The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).

I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.

I used those points because they were the most accurate ones that I know for now.

Also, remember the formula is, "y = mx + b."

natulia [17]

Answer:

I= 84

Step-by-step explanation:

for

I=\int\limits^{}_{} \int\limits^{}_D {x*y}  \, dA =  \int\limits^{}_{} \int\limits^{}_D {x*y}  \, dx*dy

since D is the rectangle such that 0<x<3 , 0<y<3

I=\int\limits^{}_{} \int\limits^{}_D {x*y}  \, dA =  \int\limits^{3}_{0} \int\limits^{3}_{0} {x*y}  \, dx*dy =  \int\limits^{3}_{0} {x}  \, dx\int\limits^{3}_{0} {y}  \, dy  = x^{2} /2*y^{2} /2 =  (3^{2} /2 - 0^{2} /2)* (3^{2} /2 - 0^{2} /2) = 3^{4} /4 = 81/4
