Answer: $171.31

Step-by-step explanation:

A = P(1 - r)ⁿ

Given: P = 200, r = 1.1% (.011), n = 14

A = 200(1 - .011)¹⁴

= 200(.989)¹⁴

= 171.308

Since we are talking about money, round to two decimal places.

The picture shows a circular clock face.

marysya [2.9K]

Answer:

[C] 25π square inches

Step-by-step explanation:

Given that:

the long hand of the clock is about 5 inches long.

To Find:

What is the approximate area of the clock face?

Solve:

Formula - A =πr²

Note that;

π = 3.14 (about)

Radius - 5 inches

A =πr²

A = 3.14(5)²

A = 3.14(25)

A = 78.5

Now let see the answer choices:

A. 5π square inches ≈ 5(3.14) = 15.7

B. 10 π square inches ≈ 10(3.14) = 31.4

C. 25 π square inches ≈ 25(3.14) = 78.5

D. 100 π square inches ≈ 100(3.14) = 314

Hence, the answer is [C] 25 π square inches

In a small town, there are 4 times as many left-handed males as there are left-handed females, and there are 3 times as many rig

horrorfan [7]

Answer:

(b) 24

Step-by-step explanation:

The given variable definitions and the given relationships let us write these statements:

LH males = 4 × LH females = 4x

RH females = 3 × RH males = 3y

LH males + RH males = 204 = 4x +y

RH females + LH females = 348 = 3y +x

Your favorite method of solving equations of this sort can tell you ...

(x, y) = (24, 108)

There are 24 left-handed females.

Additional comment

Other numbers involved here are ...

y = 108 . . . . right-handed males

204-108 = 96 . . . . left-handed males (=4×24)

348-24 = 324 . . . . right-handed females (=3×108)

If you want to solve the equations by hand, you can use substitution for y to get an equation in x:

3(204 -4x) +x = 348 ⇒ -11x = -264 ⇒ x = 24

Parallelogram Property: opposite angles are congruent Solve for x

Anna11 [10]

Answer:

Step-by-step explanation:

Equate the two opposite Angles

7x - 31 = 5x + 13 Subtract 5x from both sides

7x - 5x - 31 = 13 Combine

2x - 31 = 13 Add 31 to both sides

2x = 13 + 31 Combine the right

2x = 44 Divide by 2

x = 44/2

x = 22

The surface area of a cone is 396π square inches. If the radius is 12 inches, find the slant height of the cone.

pshichka [43]

Answer:

Slant height = 33 inches

Step-by-step explanation:

r = 12 inches

Lateral Surface Area of cone = 396π square inches

πrl = 396π

π * 12 * l = 396π

$l=\frac{396\pi }{12*\pi }\\$

l = 33 inches
