Given:

The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.

To find:

The constant of proportionality

Solution:

We have,

[tex]P=0.25n[/tex]       ...(i)

where P is the price and n is the number of bananas.

Price P is directly proportional to the number of bananas. So,

[tex]P\propto n[/tex]

[tex]P=kn[/tex]            ...(ii)

Where, k is the constant of proportionality.

On comparing (i) and (ii), we get

[tex]k=0.25[/tex]

Therefore, the constant of proportionality is 0.25.

Answer:

Length = 18 meters

Step-by-step explanation:

Let the length of the rectangular pool = l meters

And breadth of the pool = w meters

Perimeter of the rectangular pool = 2(l + 2w)

Since, perimeter of the rectangular pool is 72 meters.

2(l + 2w) = 72

l + 2w = 36 --------(1)

If length of the pool is twice of its breadth,

l = 2w

w = [tex]\frac{l}{2}[/tex] -------(2)

By substituting the value of 'w' from equation (2) to equation (1),

[tex]l+2\times{\frac{l}{2}}=36[/tex]

2l = 36

l = 18 meters

Answer:

The formula for finding the Circumference of a circle is: C = πd where d represents the diameter of the circle. The formula may also be written: C = 2πr where r is the radius of the circle. Example 1: The diameter of a circle is 16 cm.

Answer:

2x^7y^6

Step-by-step explanation:

you do x^5 = X x X x X x X x X and x^2 is X x X so X^5 x X^2 is X x X x X x X x X x X x X which can be simplified to X^7

and the same for y

y^4 = Y x Y x Y x Y and y^2 is Y x Y, so Y^4 x Y^2 = Y x Y x Y x Y x Y x Y  which simplifies to Y^6

I hope thats right :)

Answer:

x = 1/4

Step-by-step explanation:

11 + 22x = 9 + 30x

subtract 22x from both sides

11 = 9 + 8x

subtract 9 from both sides

2 = 8x

divide both sides by 8

2/8 = x

simplify

Answer:

  179 ft

Step-by-step explanation:

The applicable trig relation is ...

  Tan = Opposite/Adjacent.

The height of the lighthouse is the opposite side of the right triangle. The adjacent side to the angle of elevation from the boat is the distance to the lighthouse base. Then ...

  tan(50°) = height/(150 ft)

  height = (150 ft)(tan(50°)) ≈ 178.76 ft

The height of the lighthouse is about 179 feet.

Answer:

The circumference is similar to the perimeter in that it is the total length needed to draw the circle.

We note the circumference as c.

c = 2πr

or

c = πd

This depends on whether or not you know the radius (r) or the diameter (d)

Let’s calculate one manually, for example.

If r = 6 cm, then the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.

Suppose you only know the diameter? If the diameter is 8 cm, then the circumference is c = π(8) = 8π or 25.1 cm, rounded to the nearest tenth.

Answer:

A

Step-by-step explanation:

We can see that the y intercept is equal to 1

which means that we have the following equation

mx+1=y

We just need to solve for m at this point

We can use the ordered pair (-2,2) to help

We know that

-2m+1=2

Solve for m

-2m=1

m= -1/2

Put this together and we get

-1/2m+1=y which is A

Answer:

5.8 × 10^(6) is greater.

Step-by-step explanation:

The 2 numbers she wants to compare are;

5.8 × 10^(6) and 2.32 x 10^(7)

Now,for her to compare easily both numbers will need to have the same powers of 10.

To this effect, let's convert the power of ten of the second number to the power of 6.

We will divide by 10 to get it.

Thus; 2.32 x 10^(7) ÷ 10 = 0.232 × 10^(6)

Comparing 0.232 × 10^(6) to 5.8 × 10^(6), we can see that they have same power of 10 but the greater number that precedes the power of 10 is 5.8.

Thus, 5.8 × 10^(6) is greater.

Based on the amount invested and the amount it grew to, the simple interest rate is 1%.

Lauren invested $50 and got $50.50 after a year.

This rate can be found by the formula:

= (Difference in investment in year 1) / Amount invested x 100%

Solving gives:

= (50.50 - 50) / 50 x 100%

= 1%

In conclusion, the rate is 1%.
