Maya makes trail mix by combining 1/3 cup of mixed nuts, 1/4 cup of dried fruit, 1/6 cup of chocolate morsels. What is the total

Vaselesa [24]

Answer:

The total amount of trial mix made by Maya is $\frac{9}{12}\ \ \ Or\ \frac{3}{4}$ .

Step-by-step explanation:

Given,

Amount of mixed nuts = $\frac{1}{3}\ cup$

Amount of dry fruits = $\frac{1}{4}\ cup$

Amount of chocolate morsels = $\frac{1}{6}\ cup$

We have to find out the total amount of trial mix made by Maya.

Solution,

Total amount of trial mix is the sum of amount of mixed nuts, amount of dried fruit and amount of chocolate morsels.

So we can frame the above sentence in equation form as;

Total amount of trial mix = Amount of mixed nuts + Amount of dry fruits + Amount of chocolate morsels

On putting the given values, we get;

Total amount of trial mix = $\frac{1}{3}+\frac{1}{4}+\frac{1}{6}$

Here we have to add the fractions.

For this we will make the denominator same.

Total amount of trial mix = $\frac{1\times4}{3\times4}+\frac{1\times3}{4\times3}+\frac{1\times2}{6\times2}=\frac{4}{12}+\frac{3}{12}+\frac{2}{12}=\frac{9}{12}\ \ \ Or\ \frac{3}{4}$

Hence The total amount of trial mix made by Maya is $\frac{9}{12}\ \ \ Or\ \frac{3}{4}$ .

Thorium -228 is a radioactive substance that decays 50% every 1.9 years. How much of a 50 gram sample will exist after 22.8 year

Evgesh-ka [11]

Answer:

$A=0.0122\ gr$

Step-by-step explanation:

The exponential decrease formula that we must use is:

$A=A_0e^ {-kt}$

Where A is the amount of thorium as a function of time

$A_0$ is the initial amount and k is the decrease rate

We know that initially there are 50 gr and that you decay 50% every 1.9 years.

$A=A_0*0.5=50*0.5 = 25\\\\t=1.9$

$25=50e^ {-k(1.9)}$

We solve the equation for k

$0.5=e^ {-k(1.9)}$

$ln(0.5)=ln(e^ {-k(1.9)})$

$ln(0.5)=-k(1.9)$

$-1.9k=ln(0.5)$

$k=-\frac{ln(0.5)}{1.9}\\\\k=0.3648$

After 22.8 years the amount of thorium that exists is:

$A=50e^ {-0.3648(22.8)}$

$A=0.0122\ gr$

Text: these two triangles are similar

puteri [66]

Answer:

26.25 cm²

Step-by-step explanation:

The area of the shaded part is the area of the shaded triangle subtract the area of the white triangle.

Since the triangles are similar then the ratios of corresponding sides are equal.

let the height of the white triangle be h, then

$\frac{12}{9}$ = $\frac{10}{h}$ ( cross- multiply )

12h = 90 ( divide both sides by 12 )

h = 7.5

shaded area = $\frac{1}{2}$ × 12 × 10 - $\frac{1}{2}$ × 9 × 7.5 = 60 - 33.75 = 26.25 cm²
