Answer:

The perimeter of a rectangle is P = 2 b + 2 h , where is the base (or width) and is the height (or length). If a rectangle is a square, with sides of length , the formula for perimeter is P s q u a r e = 2 s + 2 s = 4 s and the formula for area is A s q u a r e = s ⋅ s = s 2

Which answer could it be??

kherson [118]

Answer:

5.9 years

Step-by-step explanation:

That is, r=0.12.

Then we have 2P = P (1 + 0.12/4)^(4t) and need only solve for time, t.

Simplifying the above equation: 2 = (1.03)^(4t)

We must isolate 4t, and then isolate t. To do this, take the common log of both sides of the above equation. We get:

log 2 = (4t) log 1.03. This gives us 4t = [log 2] / [log 1.03], or

4t = 23.4498

Dividing both sides by 4, we get t = 5.86 (years).

round that to 5.9 years

What is the diameter of the following?

Tamiku [17]

Answer:

12

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 9)² + (y - 4)² = 36 ← is in standard form

with r² = 36 ⇒ r = $\sqrt{36}$ = 6

diameter = 2 × r = 2 × 6 = 12

Can anyone please help

lilavasa [31]

Answer:

Adult tickets = $73.5

Child tickets = $20.5

Step-by-step explanation:

${ \rm{3x + 5y = 50 - - - \{eqn \: 1 \}}} \\ { \rm{x + 5y = 31 - - - \{eqn \: 2 \}}} \\$

• Subtract eqn 2 from eqn 1:

${ \rm{2x = 21}} \\ { \rm{x = 10.5}}$

${ \rm{10.5 + 5y = 31}} \\ { \rm{5y = 20.5}} \\ { \rm{y = 4.1}}$

A farmer has one square mile land . If he divides his land into square fields that are 1/4 mile long and 1/4 mile wide,how many

White raven [17]

A square field that is 1/4 mile long and 1/4 mile wide has area

$\dfrac{1}{4} \cdot \dfrac{1}{4} = \dfrac{1}{16}$

So, to know how many of these fields fit in the biggest field, you have to divide their areas:

$\dfrac{1}{\frac{1}{16}} = 16$

So, if the farmer divides his land into square fields that are 1/4 mile long and 1/4 mile wide, he will have 16 of these smaller fields.
