Step-by-step explanation:

A person invested $2,500 in an account growing at a rate allowing the money to double every 11 years. How long, to the nearest tenth of a year would it take for the

value of the account to reach $3,800?

The formula for exponential growth given as:

A(t) = Ao (1/2)^t/t½

A(t) = Amount after time t = $3,800

Ao = Initial amount invested = $2500

t = Time in years

t½ = Time it takes to double = 11 years

Hence,

3800 = 2500(1/2)^t/11

Divide both sides by 2500

3800/2500 = 2500(1/2)^t/11/2500

30 % + 10 % = 40 %

40 % of $50 = $20

%50 - $20 = $30

Answer:

7.722cm^2, x=129

Step-by-step explanation:

12*12=144- area of the whole square

the diameter for the circle is 12

radius is 6

Area for circle= pi* r²

3.142*6^2=113.112

144-113.112=30.888

30.888/4=7.722

Given:

Angle 1 = 90 (An)

Angle 2= 45 (An)

Angle 3 = 36 (An)

Step-by-step explanation:

Answer:

38 cm

Step-by-step explanation:

The perimeter is the sum of the sides

Starting from the left and going clockwise, then

9 + (10 - 6) + (9 - 2) + 6 + 2 + 10

= 9 + 4 + 7 + 6 + 2 + 10

= 38

Answer: 35 cm

Step-by-step explanation: to find the perimeter you add all the sides but sense there is on side that doesn't have a number you subtract 2 from nine then add all the sides plus 7.

Given:

The length of your family's garden is 3 feet greater than the width.

The area of the garden is 460 square feet.

To find:

The dimensions of the garden.

Solution:

Let x feet be the width of the garden. Then,

Length = [tex]x+3[/tex] feet

The area of a rectangle is:

[tex]A=l\times w[/tex]

Where, l is the length and w is the width of the rectangle.

The area of the rectangular garden is:

[tex]A=(x+3)\times x[/tex]

[tex]A=x^2+3x[/tex]

It is given that the area of the garden is 460 square feet.

Putting [tex]A=460[/tex], we get

[tex]460=x^2+3x[/tex]

[tex]0=x^2+3x-460[/tex]

Splitting the middle term, we get

[tex]x^2+23x-20x-460=0[/tex]

[tex]x(x+23)-20(x+23)=0[/tex]

[tex](x+23)(x-20)=0[/tex]

[tex]x=-23,20[/tex]

The width of a garden cannot be negative. So, [tex]x=20[/tex].

Now,

[tex]l=x+3[/tex]

[tex]l=20+3[/tex]

[tex]l=23[/tex]

Therefore, the length of the garden is 23 feet and the width of the garden is 20 feet.

Answer:

D

Step-by-step explanation:

It looks like triangle MNO and PQR are similar because PQR is a smaller version of MNO reversed. If this is true, MN is equal to PQ, OM is equal to RP, and ON is equal to RQ. Therefore, the answer should be D.

Write an expression for 213 increased by d: [tex]213+d=x[/tex]

Answer: 11

Step-by-step explanation:

Answer:

Step-by-step explanation:

The figure drawn is a circle.  It's center is a (-5,4) just the opposite of what is in the brackets.  I'm giving you this information just to be complete.

For a circle the radius is found using the lone number on the other side of the equal side -- in this case 121

The radius is the square root of that lone number.  

radius^2 = 121

sqrt(radius^2) = sqrt(121)

radius = 11

Answer:

3052.08 m³

Step-by-step explanation:

[tex]\boxed{volume \: of \: sphere = \frac{4}{3}\pi {r}^{3} }[/tex]

Given that the radius is 9m, r=9.

Volume of sphere

[tex] = \frac{4}{3} (3.14)(9^{3} )[/tex]

= 3052.08 m³

Answer:

Volume = 4/3 • π • r³

Volume = 4/3 • 3.14 • (9)³

Volume = 4/3 • 3.14 • 9 • 9 • 9

Volume = 4 • 3.14 • 27 • 9

Volume = 3052.08 cm³

Step-by-step explanation:

30x30

Answer:

2x² + 23

Step-by-step explanation:

Distribute the -5 and combine like terms.

7x² + 3 - 5(x² - 4) =

= 7x² + 3 - 5x² + 20

= 2x² + 23

Answer:

it looks like the answer to this problem is $280.

Step-by-step explanation:

i got this answer because you add $100 and $250 together. You will get $350. Then you take 20% of that total. So, 20% of 350 is 70. Now take 350-70, which = 280. and that should be your final answer.
