Banu will build a fence around a rectangular
30-foot-by-25-foot play area. Given that fencing costs
$4.05 per foot, how much will the fencing cost for
Banu to completely surround the play area?

Answers

Answer:

A

Step-by-step explanation:

Dimension of the rectangular fence:

Length = 30 ft

Width = 25 ft

Perimeter of the rectangular fence = 2(L + W)

= 2(30 + 25) = 2(55)

Perimeter = 110 ft

Fencing cost per foot = $4.05

Fencing cost for 110 ft = 110 × 4.05 = $445.50

Answer:

X = 49

Step-by-step explanation:

The top angle that measures 126° is a mirrored version of the angle measuring  (x + 77)°. The means the angle, (x + 77)°, has to measure 126°. So, to get x you have to subtract 126 by 77 and that gives you 49.

What is the value of x?
40
55
A. 95
B. 85
C. 750
D. 105

Answers

Answer:

B. 85

Step-by-step explanation:

A triangle has a total of 180 degrees.

85 + 55 = 140

140 + 40 = 180

Your answer is B. 85

The value of x is 85°

What is sum of angles of triangle ?

The sum of interior angles of a triangle are 180°

If ∠A, ∠B, ∠C are three interior angles of a triangle,

Then ∠A+∠B+∠C = 180°

What is the required angle ?

Given that, Two angles of the triangle are 40° & 55°

Let, the third angle be x.

Then, Sum of angles = 180°

     ⇒ 40°+55°+x = 180°

     ⇒ x+95° = 180°

     ⇒ x = 180°-95°

     ⇒ x = 85°

The value of x = 85°

The formula for compound interest is:

Where:

A = the future value of the investment (including interest)
P = the principal investment amount (the initial deposit amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested for

If Josh invests $500 in a 5-year fixed interest savings bond that pays 5% per annum, how much will his entire investment be worth at the end of the term?

Answers

Answer:

Future value, A = $642

Step-by-step explanation:

Given the following data;

Principal = $500

Interest rate = 5% = 5/100 = 0.05

Time, t = 5 years

n = 365

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 500(1 + \frac{0.05}{365})^{365*5}[/tex]

[tex] A = 500(1 + 0.000137)^{1825}[/tex]

[tex] A = 500(1.000137)^{1825}[/tex]

[tex] A = 500*1.2840 [/tex]

Future value, A = $642

uppose that you live in a community that has 1,250 households. Among these households, 500 have traditional landline telephones while the remaining 750 only use cellular and / or VOIP telephones. We are going to select 100 households from your community at random without replacement. The first household selected does not have a traditional landline telephone. What is the probability that the second household selected will have a traditional landline telephone

Answers

Answer:

0.4003 = 40.03% probability that the second household selected will have a traditional landline telephone.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The first household selected does not have a traditional landline telephone.

This means that of 1250-1 = 1249 households, 500 have traditional landline telephones.

What is the probability that the second household selected will have a traditional landline telephone

500/1249 = 0.4003

0.4003 = 40.03% probability that the second household selected will have a traditional landline telephone.
