Ann increased the quantities of all the ingredients in a recipe by 60% 60, percent. She used 808080 grams (g) of cheese. How muc

Alexus [3.1K]

Answer:

50 gram

Step-by-step explanation:

The actual percentage recipe = 100%

Percentage Increase in recipe = 60%

Recipe used as a result of increment = 80 gram

Hence,

100% + 60% = 80

160% = 80g

If :

160% = 80

100% = x

Cross multiply

1.6x = 80 * 1

1.6x = 80

x = 80 / 1.6

x = 50

Recipe required 50 gram

Iodine-125 has a half-life of about 60 days.

Murljashka [212]

62.5 mg sample will remain after 240 days

Step-by-step explanation:

Given

Half-life = T = 60 days

The formula for calculating the quantity after n half lives is given by:

$N = N_0(\frac{1}{2})^n$

Here

N is the final amount

N_0 is the initial amount

n is the number of half lives passed

The number of half lives are calculated by dividing the time for which the remaining quantity has to be found by half life

The quantity has to be calculated for 240 days so,

$n = \frac{240}{60}\\n = 4$

Given

$N_0 = 1000\ mg$

Putting the values in the formula

$N = 1000 (\frac{1}{2})^4\\=1000 * \frac{1}{16}\\=\frac{1000}{16}\\=62.5\ mg$

Hence,

62.5 mg sample will remain after 240 days

Expand and combine like terms. (4b^2+ 3) (4b^2- 3) = 1 SEE ANSWER

krok68 [10]

Answer:

Step-by-step explanation:

(4b^2+3)(4b^2-3)

since it is the expanded form of formula a^2-b^2=(a+b)(a-b) we can write,

=(4b^2)^2-(3)^3

=16b^4-9

Find the slope of the line that passes through each pair of points.

e-lub [12.9K]

Answer:

0.5

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

= 0.5

θ =

arctan( ΔY ) + 180°

ΔX

= 206.56505117708°

ΔX = 0 – 2 = -2

ΔY = 0 – 1 = -1

Distance (d) = √ΔX2 + ΔY2 = √5 = 2.2360679774998

Equation of the line:

y = 0.5x

When x=0, y = 0

When y=0, x = -0
