The largest possible circle is cut out of a square whose side length is 8 feet. What will be the approximate area, in square fee

Lunna [17]

Answer:

=13.73 ft²

Step-by-step explanation:

The diameter of the largest possible circle that can be cut out of a square is equal to the length of the side of the square.

Therefore the diameter of the circle cut from a square of side 8ft =8ft

r=4ft

Area of the remaining board= Area of square- area of circle

=side²-πr²

=8²-π×4²

=64-16π

=13.73 ft²

The radioactive substance polonium-210, with a half-life of 138.39 days, is present in tobacco. Suppose that the soot in an ex-s

Ksju [112]

Answer:

16.07 milligrams

Step-by-step explanation:

From the question,

Using the formula of radioactive decay,

R/R' = 2ᵃ/ᵇ..................... Equation 1

Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.

Make R' the subject of the equation

R' = R/(2ᵃ/ᵇ)................ Equation 2

Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days

Substitute these values into equation 2

R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)

R' = 100/(6.222)

R' = 16.07 milligrams of plonium-210

Suppose a video store charges non-members $4 to rent a video. A membership costs $21 and then videos cost only $2.50 to rent. Ho

densk [106]

Answer:

You need to rent 14 videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.

Step-by-step explanation:

Let Number of videos to be rented be x;

Given:

For non members;

Cost of renting 1 video = $4

Cost for renting x videos = $4x$

For Members;

Membership cost = $21

Cost of renting 1 video = $2.50

Cost of renting x video = $2.5x$

We can create an equation. Say the number of videos you rent is given by x . We can write that, if we rent x videos without membership, we'll have to pay $4x$ . If we rent the same amount of videos with membership, we'll have to pay $21+2.5x$ .

Hence the equation can written as

$4x=21+2.5x\\4x-2.5x=21\\1.5x=21\\x=\frac{21}{1.5}=14$

Hence You need to rent 14 videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.

PLEASE HELP! Given: △MNO m∠M=45°, m∠O=30° MN=6 Find: NO, MO.

zubka84 [21]

Answer:

NO = 8.48 units, MO = 11.59 Units

Step-by-step explanation:

∠M = 45°

∠O = 30°

∠N = 180-(45+30)

∠N = 105°

MN=6 = o

NO = m

MO = n

From sine rule

$\frac{sinM}{m}=\frac{sinN}{n}=\frac{sinO}{o}$

$\\\Rightarrow \frac{sinO}{o}=\frac{sinM}{m}\\\Rightarrow m=\frac{sinM}{\frac{sinO}{o}}\\\Rightarrow m=\frac{sin45}{\frac{sin30}{6}}\\\Rightarrow m=8.48$

$\frac{sinO}{o}=\frac{sinN}{n}\\\Rightarrow n=\frac{sinN}{\frac{sinO}{o}}\\\Rightarrow n=\frac{sin105}{\frac{sin30}{6}}\\\Rightarrow n=11.59$

∴ NO = 8.48 units, MO = 11.59 Units
