Answer:

0.026 m / min.

Step-by-step explanation:

Volume V = π7^2h

V = 49πh

dV/dh = 49π

Rate that the volume is increasing is 4 m3/min.

So dV/dt = 4

dV/dt = dh/dt * dV/dh

4 = dh/dt * 49π

dh/dt = 4/49π

= 0.026 m / min.

The required height of the water increase is given as 0.026 m/min.

Given that,
A cylindrical tank with a radius of 7 m is being filled with water at a rate of 4 m3/min, how fast is the height of the water increasing is to be determined

Volume is defined as the ratio of the mass of an object to its density.

Here,
The volume of the cylinder =πr²h
Substitute the value in the above formula
Volume V = π7²h
V = 49πh
V/h = 49π  - - - - - - - (1)

Rate of the filling the tank is given,

V/t = 4
V = 4t
Substitute this in equation 1

4t / h = 49π
h / t = 0.026 m/s.

Thus, the required height of the water increase is given as 0.026 m/min.

Answer:

let the amount deposited by each of them in march be m.

in April, Isaiah deposited 210$, this means the amount in his account became m+210

Freddie increased the amount by 15%, this means that the amount of money in his account became: m+0.15m

since both values are still equal, we will equate both equations and solve for m.

m+210 = m+0.15m

0.15m = 210

m = 1400$

Answer:

y=-[tex]\frac{5}{8}[/tex]x-5

Step-by-step explanation:

Start with the slope equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex].

[tex]\frac{-10-(-5)}{8-0}=\frac{-5}{8}[/tex]

This is the slope of your equation

Now rearrange the slope-intercept equation to get your y-intercept

y=mx+b

y-mx=b

Now substitute either of your two points to find your y-intercept

-10-(-[tex]\frac{5}{8}[/tex](8))=b

-10-(-5)=b

-10+5=b

b=-5

Now that you have slope and the y-intercept you can write your equation:

y=-[tex]\frac{5}{8}[/tex]x-5

We are required to find the equivalent fraction of the family’s budget that is spent on housing

fraction of the family’s budget that is spent on housing is 7/25

let

Total budget of the family = x

Monthly housing budget = 28%

percentage monthly housing budget = 28% of x

= 28/100 × x

= 0.28x

Fraction of the family’s budget that is spent on housing = 28/100 × x

= 7/25 × x

= 7/25x

Therefore, fraction of the family’s budget that is spent on housing is 7/25

Comparing the equivalent cost of Milk in Euro in the two countries, then we can conclude that Milk is a better value for money in Paris.

In other to make accurate comparison of the cost ; we need to using the same unit or milk and same currency value :

Cost of 1 pint of Milk in London :

1 pint = 0.58 pounds

The equivalent value of 1 pint of Milk in terms of Euro in London will be :

1 pound = 1.17 euro

0.58 pound = x

Cross multiply :

x = 1.17 × 0.58

x = 0.6786 euro

x = 0.68 euro

Hence, 1 pint of Milk cost 0.68 euro in London

Cost of 1 pint of Milk in Paris :

1 Litre = 1.76 pint

Hence,

1.76 pint = 1.05 euro

1 pint = c

1.76c = 1.05

c = 1.05 / 1.76

c = 0.597 euro

Hence, cost of 1 pint of Milk cost 0.60 euro in Paris

Therefore, since the cost of Milk in Paris cost less in Paris than in London, then Milk is a better value for money in Paris.

Step-by-step explanation:

Point Slope Form: (y - y₁) = m(x - x₁)

4. y - 4 = 0.8(x - 2)

   - To make it slope-intercept form

   y - 4 = 0.8x - 1.6

   y = 0.8x + 2.4

5. (Use slope finding formula) 4 - 10 / -2 - (-5) = 2

   y - 4 = 2(x + 2)

   - To make it slope-intercept form

   y - 4 = 2x + 4

   y = 2x + 8
