4/5 plus 2/3 and in simplest terms is 22 / 15

<h3>Step by Step calculation :</h3>

Given that

= 4 / 5 + 2 / 3

We will multiply 4 by 3 to get 12 and then multiply 2 by 5 to get 10

= 3 * 4 / 5 + 5 * 2 /3

= 12 / 5 + 10 / 3

Next we give both terms new denominators 5 × 3 = 15

= 12 / 5 + 10 / 3

= (12 + 10) / 15

Then, the fraction would be :

= (12 + 10) / 15

= 22 / 15

Answer:

$\huge\boxed{\fcolorbox{red}{orange}{Answer : }}$

Given~

$\frac{4}{5} + \frac{2}{3}$

Step-by-step explanation:

So we multiply 4 by 3, and get 12.

Then we multiply 2 by 5, and get 10.

Next we give both terms new denominators 5 × 3 = 15.

So now our fractions look like this~

$\frac{12 + 10}{15}$

$\frac{22}{15}$

1. Writing an equation for an exponential function by

Naya [18.7K]

Answer: 1) $t(n)=0.6(2)^n$

2) $f(x)=10(5)^x$

Step-by-step explanation:

1) Let the function that shows the thickness of the paper after n folds,

$t(n) = ab^n$ ---------(1)

Since, According to the question,

Initially the thickness of the paper = 0.6

That is, at n = 0, t(0) = 0.6

By equation (1),

$0.6 = a(b)^0\implies 0.6 = a$

Hence the function that shows the given situation,

$t(n) = 0.6 b^n$ -----------(2)

Again when we fold the paper the thickness of the paper will be doubled.

Thus, at n = 1, t(1) = 1.2

By equation (2),

$1.2 = 0.6 b^1\implies 2 = b$

Thus, the complete function is,

$t(n) = 0.6 (2)^n$

2) Let the function that is passing through the points (-2, 2/5) and (-1,2),

$f(x) = ab^x$ ---------(1)

For f(x) = 2, x = -1

By equation (1),

$2= ab^{-1}$ ---------(2)

Also, For f(x) = 2/5, x = -2

Again, By equation (1),

$\frac{2}{5}= a(b)^{-2}$

$\implies \frac{2}{5}=ab^{-1}b^{-1}=2b^{-1}$

$\implies \frac{2}{5}=\frac{2}{b}$

$\implies 2b=10$

$\implies b = 5$

By substituting this value in equation (2),

We get, a = 10

Hence, from equation (1), the function that is passing through the points (-2, 2/5) and (-1,2),

$f(x) = 10(5)^x$

Wildflower mix contains several different types of seeds.

Sveta_85 [38]

The chance would be 9.52% (rounded) because you would take the total number of seeds (63) and divide the number of poppy seeds by the total.
Then you would convert decimal fraction by multiplying it by 10.
