How is length of chord related to length of a diameter

Mathematics
1 answer:
Andrew [12]3 years ago
6 0
This means that it sweeps out half of the circle so that the chord is actually going across the whole diameter of the circle. So if the chord is going across the diameter and has a length of 15 inches, then the radius of the circle should be 7.5 inches. read more at: https://www.ck12.org/trigonometry/Length-of-a-Chord/lesson/Length-of-a-Chord-TRIG/

Alisiya [41]

A house on the market was valued at $327,000. after several years the value increased by 17% by how much did the house's value increase in dollars? what is the current value of the house?

How much did the house's value increase in dollars?

327,000 x 0.17 (17%) = $55,590

What is the current value of the house?

327,000 + 55,590 = $382,590

Two certificates of deposit pay interest at rates that differ by 4%. Money invested for one year in the first CD earns $175 inte
wolverine [178]
We are told that the principle is the same for both investments so we can say:

315=P(r+4)/100 and 175=Pr/100 solving both for P you have:

P=31500/(r+4) and P=17500/r since P=P:

17500/r=31500/(r+4)

175(r+4)=315r

175r+700=315r

-140r+700=0

-140r=-700

r=5

So the rates are 5% and (5+4)=9%

check...

P(9/100)=315  and P(5/100)=175

P=31500/9 and P=17500/5

P=157500/45 and P=157500/45

So P=P

note:  P=$3500

3500(9/100)=$315

3500(5/100)=$175

Solve for x. 6x - 15 = 9x - 6
PolarNik [594]
Subtract 6x from 9x
-15=3x-6
add 6 to both sides
-9=3x
divide 3 from both sides and -3=x

The wholesale price of a flower arrangement was $60 and the flowers were marked up 30%.
SpyIntel [72]

Answer:

Marked up Price = $61.80

Step-by-step explanation:

we are given that The wholesale price of a flower arrangement was $60 and the flowers were marked up 30%.

Hence Marked price = increased price + Wholesale price

Increased price = 30% of whole sale price

= 0.30 x $60

=$1.8

Marked up Price = $1.8+$60

= $61.80
