Stefan borrowed $8,950
for an engagement ring. At
a 6.85% simple interest rate,
how much total will he have
paid after 6 years?

Answers

Answer 1

The amount after 6 years is $12,628.45

Simple interest

The formula for calculating the compound interest is expressed as:

I = PRT

P is the principal = $8,950r is the rate = 6.85% = 0.0685T is the tim = 6 years

Get the interest

I = 8950 * 0.0685 * 6

I = $3,678.45

Amount after 6 years  = 8950 + 3,678.45

amount after 6 years = $12,628.45

Hence the amount after 6 years is $12,628.45

If XY is median then CD equals 16

Length of CD = 16 .

What is Isosceles trapezoid?

An isosceles trapezoid can be defined as a trapezoid in which non-parallel sides and base angles are of the same measure.

Given,

Isosceles trapezoid ABCD with median XY.

Median cuts the non-parallel lines of trapezoid in two equal parts.

then,

AX = 8

AB = 2 × AX

AB = 2 × 8

AB = 16

ABCD is isosceles trapezoid

So, Unparallel lines are equal,

AB = CD

⇒ CD = 16 unit.

Hence, 16 unit is length of CD.

Answer:

Step-by-step explanation:

Now e have two figures

1 is ABCD and other is APQD ,

Now to find g and f,

Now the are both figure is ,

Area = length * width

Area ABCD = 39 cm^2

AB* BC = 39

(g+7) * ( f) = 39

Again,

Area APQD = AP*QD= 16 cm ^2

(g)*(f)=16

from here f =16/g  putt it in above equation we get ,

(g+7)*16/g = 39

16*g-39*g+96 =0

-23g +96 = 0

g = 96/23

g =3 cm

Now for f putt in one of the above equation ,

f =16/3

f =5.33 cm

Answer:

f = 3cm g = 6cm

Step-by-step explanation: to find f

Subtract the area of APQD from ABCD then divide by 7

f = (39 - 18)/7

f = 21/7

f = 3

To find g, divide the area of APQD by 3

18/3 = 6

We can do this because of the givens: ABCD is a rectangle, PQ is parallel to AD, so BC=AD=PQ

A factory makes rods by cutting plastic pipes that are 5 feet long into 8 rods.

How long is each rod?

Answers

Ok let’s start off with- how long is 5 feet? That would be 12x5 which is 60. 60/8 which is 7.5!!!

Feet is the unit of measurement. One feet of measurement is equal to the 12 inches.The length of the each rod made by the 5 feet long pipe is 7.5 inches.

Given-

The length of the pipes is 5 feet.

Total number of roads made by the pipes is 8.

We need to convert the length of the feet into the inches.

How many inches are there in one feet?

Feet is the unit of measurement. One feet of measurement is equal to the 12 inches.

As it is known that the one feet has the twelve inches. Thus the number of inches in 5 feet is,

[tex]=5\times12[/tex]

[tex]=60[/tex]

Thus the length of the pipe is 60 inches.

Now the total number of roads made by this pipe is 8. Suppose the length of the each rod is [tex]x[/tex] inch. Thus,

[tex]x=\dfrac{60}{8}[/tex]

[tex]x=7.5[/tex]

Thus the length of the each rod made by the 5 feet long pipe is 7.5 inches.

A rectangular box without a top is have a volume of 12 cubic feet. Find the dimensions of
the box that will have minimum surface area.​

Answers

If the length, breadth and height of the box is denoted by a, b and h respectively, then V=a×b×h =32, and so h=32/ab. Now we have to maximize the surface area (lateral and the bottom) A = (2ah+2bh)+ab =2h(a+b)+ab = [64(a+b)/ab]+ab =64[(1/b)+(1/a)]+ab.

We treat A as a function of the variables and b and equating its partial derivatives with respect to a and b to 0. This gives {-64/(a^2)}+b=0, which means b=64/a^2. Since A(a,b) is symmetric in a and b, partial differentiation with respect to b gives a=64/b^2, ==>a=64[(a^2)/64}^2 =(a^4)/64. From this we get a=0 or a^3=64, which has the only real solution a=4. From the above relations or by symmetry, we get b=0 or b=4. For a=0 or b=0, the value of V is 0 and so are inadmissible. For a=4=b, we get h=32/ab =32/16 = 2.

Therefore the box has length and breadth as 4 ft each and a height of 2 ft.

When playing the roulette at a casino, you have exactly 1/35 chance of winning in each round if you play a single number. Your friend has rigged up some fireworks to be set off when you win. When you win, he sets off the fireworks every time. When you don't win, he accidentally sets off the fireworks 10% of the time. If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?

Answers

Answer:

0.2275 = 22.75% probability that you actually won that round

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Fireworks going off

Event B: You won

Probability of fireworks going off.

100% of 1/35 = 0.0286(when you win)

10% of 34/35 = 0.9714(you lost). So

[tex]P(A) = 0.0286 + 0.1*0.9714 = 0.12574[/tex]

Probability of you winning and fireworks going off:

100% of 1/35, so [tex]P(A \cap B) = 0.0286[/tex]

If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0286}{0.12574} = 0.2275[/tex]

0.2275 = 22.75% probability that you actually won that round
