St Is Tangent To Q Find The Value Of R

Answers

Answer 1

Answer:

r = 7

Step-by-step explanation:

The angle between the tangent ST and the radius QS at the point of contact is 90° , then

Δ QST is right

Using Pythagoras' identity in the right triangle

(r + 18)² = r² + 24² , that is

r² + 36r + 324 = r² + 576 ( subtract r² from both sides )

36r + 324 = 576 ( subtract 324 from both sides )

36r = 252 ( divide both sides by 36 )

r = 7

2/5 divided by 1 7/8 in the as a fraction in it simplest form

Answers

hope this helps dude

The fraction to represent the 2/5 divided by [tex]1\frac{7}{8}[/tex] is 16/75.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, 2/5 divided by [tex]1\frac{7}{8}[/tex] =15/8.

Here, 2/5 ÷ 15/8

When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal. Finding the reciprocal of the second fraction reversing its numerator and denominator is the first step in dividing fractions. Multiply the two numerators after that. Multiply the two denominators after that.

2/5 × 8/15

= 16/75

Therefore, the fraction is 16/75.

Wallpaper was applied to one rectangular wall of a large room. Width: 42 ft length:25.5 ft. If the total cost of the wallpaper was $771.12, what was the cost, in dollars, of the wallpaper per square foot?

Answers

Answer:

$825869.52

Step-by-step explanation:

Given that,

Width of the rectangle, b = 42 ft

Length of the rectangle, l = 25.5 ft

The area of a rectangle is given by :

A = lb

So,

A = 42 ft × 25.5 ft

A = 1071 ft²

The total cost of the wallpaper was $771.12 . So,

Cost = 1071 × 771.12

= $825869.52

So, the cost of wallpaper per square foot is equal to $825869.52.

Jack has $500 in a bank account that will earn 3% interest every year. Diane has $100 in an investment account that will earn 12% every year. How many years will it take for Diane's account balance to overtake Jack’s?

Answers

Answer:

20 years

Step-by-step explanation:

A=500(1+.03)^20

$903

A=100(1+.12)^20

$964

It took her 20 years to overtake.

Answer:

Simple interest = NeverCompound interest = 19 years and 4 months

Step-by-step explanation:

Jack

Initial amount = $500Interest rate = 3% = 0.03

Yearly interest = 0.03*500 = $15

Diane

Initial amount = $100Interest rate = 12% = 0.12

Yearly interest = 0.12*100 = $12

Diane's initial amount and yearly interest amount are both less than of Jack's.

It means her balance will never overtake Jack's.

=======================

It is not mentioned in the question but let's assume it is compound interest which is annually compounded.

Then after x years their balance will be:

Jack

500(1 + 0.03)^x = 500*1.03^x

Diane

100(1 + 0.12)^x = 100*1.12^x

Solve inequality below:

100*1.12^x ≥ 500*1.03^x(1.12/1.03)^x ≥ 51.087^x ≥ 5x log 1.087 ≥ log 5x ≥ log 5 / log 1.087x ≥ 19.29 years = 19 years and 4 months

An auditorium has 21 rows of seats. The first row has 18 seats and each succeeding row has 2 more seats than the previous row. How many seats are in the auditorium?

Answers

Answer:

798

Step-by-step explanation:

So, 21*{2*18 + (21-1)*2}/2

= 21*{36 + 20*2}/2

= 21*{36+40}/2

= 21*76/2

= 1596/2

= 798

Total number of seats is 798

Given that;

Number of seats in first row = 18

Number of rows = 21

Each row added number of seats then previous = 2

Find:

Total number of seats

Computation:

Total number of seats = Sn = (n/2)[2a + (n-1)d]

Total number of seats = Sn = (21/2)[2(18) + (21-1)2]

Total number of seats = (21/2)[36 + (20)2]

Total number of seats = (21/2)[36 + 40]

Total number of seats = (21/2)[76]

Total number of seats = (21)(38)

Total number of seats = 798
