Answer:

7 inches and 5 inches

Step-by-step explanation:

The length the length and width of the rectangle be l and b.

Accodrding to question,

Width, b = l-2

Perimeter, P = 24 inches

We know that,

The perimeter of a rectangle is given by :

P = 2(l+b)

24 = 2(l+l-2)

12 = 2l-2

14=2l

l = 7 inches

Width, b = 7-2 = 5 inches

Hence, the length and width of the rectangle are 7 inches and 5 inches respectively.

Answer:

let r ,v be the radius and volume of sphere.

dv/dt=64πft³/min

r=2ft

Dr/dt=?

Step-by-step explanation:

we have

volume of sphere=4/3πr²

v=4/3πr²

differentiating both side with respect to t we get

dv/dt=4πdr²/dr×dr/dt=4π×2r×dr/dt=8/3×πr×dr/dt

substituting the given value we get

dv/dt=8/3×πr×dr/DT

64π×3/(8π×2)=dr/dt

Dr/dt=12ft/min

The balloon's radius is increasing at a rate of12 ft/min

The balloon's radius increasing at the instant the radius is 2 ft will be 10106.47 ft³ per minute.

The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.

A spherical balloon is inflating with helium at a rate of 64π ft/min.

dr/dt = 64π ft/min

Then the balloon's radius increasing at the instant the radius is 2 ft will be

V = (4/3)πr³

Differentiate with respect to time. Then we have

[tex]\rm V' = \dfrac{dV}{dt} \\\\ V' = \dfrac{4}{3}\cdot \pi 3r^2 \cdot \dfrac{dr}{dt}[/tex]

Simplify the equation, then we have

V' = 4πr² × 64π

V' = 4π × (2)² × 64π

V' = 10106.47 ft³ per minute

The balloon's radius increasing at the instant the radius is 2 ft will be 10106.47 ft³ per minute.

He spent 20% of his exercise time for the week on Monday!

How I got this is by finding the total amount of time spent exercising in the week and the total amount of exercise on Monday. I found that one fifth (1/5) of his exercise time was spent on Monday, or in percentage form, 20%!

Hope this helps, if not, comment below please!!!

Answer:

  12x +12y = 7

Step-by-step explanation:

The 2-point form of the equation for a line is useful.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (1/3 -1/4)/(1/4 -1/3)(x -1/3) +1/4

  y = (1/12)/(-1/12)(x -1/3) +1/4)

  y = -x +1/3 +1/4

Add x and multiply by 12.

  x +y = 1/3 +1/4

  12x +12y = 4 +3

  12x +12y = 7

Answer:4.08 ft a year or 1 and 5/8 feet a year (approx)

Step-by-step explanation:

It's  12.5 feet the first year

51 feet 5 years later

If you do the math and divide 51 by 12.5, you get 4.08 which is around 1 and 5/8 ft

12.5x4.08 is  51 feet.

So the tree grows approximately 1 and 5/8 feet a year

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

Given that;

Louis invested £2950 in a savings account for 5 years.

He was paid 1.9% per annum compound interest for each of the first 4 years.

And, He was then paid R% interest for the fifth year.

Louis had £3257 in his savings account at the end of the 5 years.

Here, We know that;

⇒ Compound interest formula = Capital × (1 + r%) ⁿ

Where, n is time in years.

So, We can formulate;

⇒ £2950 × (1 + 0.019)⁴

⇒ £3180.67

And, For calculate R;

⇒ £3180.67 × (1 + R%)⁵ = £3257

⇒ R = 2.4%

For the given triangle the measure of the angle y is 65°.

Hence the correct option is C.

The angles that are created outside of a triangle are its external angles.

In other terms, the angle created between one of a triangle's sides and its neighboring extended side is the triangle's exterior angle.

And the exterior angle of a triangle is the sum of the interior angles of opposite sides.

The given angles are:

Exterior angle =  130°

Interior angles are y° and y°

Therefore,

Exterior angle  = y° + y°

130° = y° + y°

2y° = 130

Dividing both sides by 2 we get,

y° = 65°

Hence,

The measure of the angle y is 65°.
