If 1 box cost rs 45 find the cost of 9 boxes

jarptica [38.1K]

Answer:

9 boxes cost Rs 405

Step-by-step explanation:

1 box costs 45.

so, how much are 2 boxes ? what do you think ?

right, twice as much : 2 × 45 = 90

how much are 3 boxes ?

now it is three times the cost of 1 box : 3 × 45 = 135

do you see the pattern ?

it is really simple.

that is also the origin why we describe a multiplication by "times". we take a single item so and so many times.

when you see something like this, you know, they are talking about multiplication.

so, here we want to know how much 9 boxes cost.

therefore,

9 × 45 = 405

is the answer.

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the

kenny6666 [7]

Given:

The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation

$y=-29x^2+1388x-10040$

To find:

The maximum amount of profit the company can make, to the nearest dollar.

Solution:

If a quadratic equation is $f(x)=ax^2+bx+c$ , then the vertex is

$Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)$

If a>0, then vertex is the minimum point and if a<0, then the vertex is the maximum point.

We have,

$y=-29x^2+1388x-10040$

Here, $a=-29,b=1388, c=-10040$ . Clearly, a<0. So, the vertex is the point of maxima.

$-\dfrac{b}{2a}=-\dfrac{1388}{2(-29)}$

$-\dfrac{b}{2a}=-\dfrac{1388}{-58}$

$-\dfrac{b}{2a}\approx 23.931$

Putting x=23.931 in the given equation, we get

$y=-29(23.931)^2+1388(23.931)-10040$

$y=-16608.09+33216.228-10040$

$y=6568.138$

The vertex is at (23.931,6568.138).

Therefore, the maximum profit is $6568.138 when x=23.931.

At a coffee shop, the first 100 customers' orders were as follows. What is the probability that a customer ordered a cold drink

mestny [16]

Answer:

Concept: Probability

You have a dual probability such that they must order a large and then get the probability from there.
So its x/probability of large
If you would have provided the table it would have been clearer
