brian family drinks a gallon of milk in three days how much gallons of milk will brian family drink in five days
Otrada [13]

To calculate this, we have to establish a proportion :

If 1 gallon of milk is drunk in 3 days,​

X gallons will be drunk in 5 days​

X gallons = 1 gallon*5days/3days = 1.66 gallons will drink in 5 days.​

​We can round to the first decimal place 1.66 ≈ 1.7 gallons approximately.

Answer : 1.7 gallons will Brian family drink in five days, approximately.​

​Hope this helps!​​​​

What is the rule if the reflection?
Mice21 [21]

Answer:

option c

r_{x-axis}->(x,-y)

Step-by-step explanation:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed), So we can see from the graph that,

point M(-5,4) is reflected to m'(-5,-4)

similarly,

point N(-2,3) is reflected to N'(-2,-3)

point L(-4,2) is reflected to L'(-4,-2)

  • About the x-axis (washer method):

\displaystyle\pi\int_2^5\left(6^2-\left(\frac43x-\frac23\right)^2\right)\,\mathrm dx=\frac{16\pi}9\int_2^5(20+x-x^2)\,\mathrm dx=\boxed{56\pi}

  • About the y-axis (shell method):

\displaystyle2\pi\int_2^5x\left(6-\left(\frac43x-\frac23\right)\right)\,\mathrm dx=\frac{8\pi}3\int_2^5x(5-x)\,\mathrm dx=\boxed{36\pi}

  • About x=7 (shell method):

\displaystyle2\pi\int_2^5(7-x)\left(6-\left(\frac43x-\frac23\right)\right)\,\mathrm dx=\frac{8\pi}3\int_2^5(35-12x+x^2)\,\mathrm dx=\boxed{48\pi}

  • About y=2 (washer method):

\displaystyle\pi\int_2^5\left((6-2)^2-\left(\frac43x-\frac23-2\right)^2\right)\,\mathrm dx=\frac{16\pi}9\int_2^5(5+4x-x^2)\,\mathrm dx=\boxed{32\pi}
