Answer:

128 miligrams for 32 days

Step-by-step explanation:

To do this question, you first need to find out how much food she feeds per day so to do this, you do 12 mg/3 days and you get 4mg/day.

Then you multiply this number by 32.

4mg/day (32 days) = 128 mg

Procedure :

12 milligrams - 3 days

(3 divided by 12 = 4)

4 - day

4 x 32 = 128

Answer :

To feed her fish for 32 days, she will need 128 milligrams of fish food.

The sum of two consecutive natural numbers is 525.<br> Find the numbers.

Luda [366]

Answer:

262 and 263 are consecutive natural numbers whose sum is 525.

Step-by-step explanation:

Natural number are a subset of real numbers consisting in positive integers (i.e. 1, 2, 3, 525) and two natural numbers are consecutive when distance between each other is equal to 1. ( $|x-y| = 1$ , $\forall\,x,y \in \mathbb{N}$ ) We can interpret the statement mathematically by means of the following expression:

$x + y = 525$

$x = n$

$y = n+1$

Where $x$ , $y$ , $n$ $\in \mathbb{N}$ .

This system is reduced to a single equation and solved afterwards:

$n +(n+1) = 525$

$2\cdot n + 1 = 525$

$2\cdot n = 524$

$n = 262$

Now we evaluate $x$ and $y$ to obtain the natural numbers:

$x = 262$

$y = 263$

262 and 263 are consecutive natural numbers whose sum is 525.

A blue die and a red die are thrown. B is the event that the blue comes up with a 6. E is the event that both dice come up even.

iVinArrow [24]

Answer:

Size of |E n B| = 2

Size of |B| = 1

Step-by-step explanation:

<em>I'll assume both die are 6 sides</em>

Given

Blue die and Red Die

Required

Sizes of sets

- $|E\ n\ B|$

- $|B|$

The question stated the following;

B = Event that blue die comes up with 6

E = Event that both dice come even

So first; we'll list out the sample space of both events

$B = \{6\}$

$E = \{2,4,6\}$

Calculating the size of |E n B|

$|E n B| = \{2,4,6\}\ n\ \{6\}$

$|E n B| = \{2,4,6\}$

<em>The size = 3 because it contains 3 possible outcomes</em>

Calculating the size of |B|

$B = \{6\}$

<em>The size = 1 because it contains 1 possible outcome</em>

LAW OF SINES??? NEED HELP.

snow_tiger [21]

Answer:

Step-by-step explanation:

We know by the Triangle Angle-Sum Theorem that the angles of a triangle all add up to equal 180. So we find angle B:

180 - 82 - 55 = 43

So angle B = 43. Now we can use the Law of Sines to solve for side b:

$\frac{sin(55)}{8}=\frac{sin(43)}{b}$

Cross multiply to get

b sin(55) = 8 sin(43) and divide to solve for b:

$b=\frac{8sin(43)}{sin(55)}$ so

b = 6.6605
