If 8 cakes cost $62.40, how much would 3 cakes cost?

Ilya [14]

Answer:

Step-by-step explanation:

Given,

Cost price of 8 cakes = $62.40

So,

Cost price of 1 cake = $ $\frac{62.40}{8}$

Therefore,

Cost price of 3 cakes

= $( $\frac{62.40}{8}$ × 3)

[On dividing 62.40 by 8]

= $(7.80 × 3)

[On multiplying]

= $23.40

Hence,

The required cost of 3 cakes is $23.40 (Ans)

What is the explicit equation for this series 25,21,17,13

Neko [114]

Answer:

The explicit rule is:

Step-by-step explanation:

The explicit rule is given by:

$a_n=a_1+d(n-1)$

The given sequence is 25,21,17,13

$a_1=25$

d=21-25

d=-4

We plug in the values into the formula to get;

$a_n=25+-4(n-1)$

$a_n=25-4n+4$

$a_n=29-4n$

he books in a private library are classified as fiction and nonfiction. There are 400 books in the library. There are 40 more fi

vfiekz [6]

First, you have to set a system of equations to determine the number of fiction and of nonfiction books.Call f the number of fiction books and n the number of nonfiction books. Then 400 = f + n. And f = n + 40 => n = f - 40 => 400 = f + f - 40 => 400 - 40 = 2f => f = 360 / 2 = 180. Now to find the probability of picking two fiction books, take into account the the Audrey will pick from 180 fiction books out of 400, and Ryan will pick from 179 fiction books out of 399, so the probability will be (180/ 400) * (179/399) = 0.20 (rounded to two decimals). Answer: 0.20
