Answer:

Class 7A collected 4.8 ounces of pure gold.

Step-by-step explanation:

<u>Key skills required are: Percentages, Multiplication</u>

<u />

  1. We only need the information about Class 7A. They collected 40 oz that contains 12% gold.
  2. In other words, this means that 12% of that 40 oz gold sand is pure gold.

Here we have to do 12% x 40 to find the number of oz of pure gold. We first have to convert 12% into a decimal. Divide it by a 100 (or move the decimal point 2 places to the left) and you will get 0.12.

<em>Do 0.12 x 40 and you will get 4.8</em>

Therefore, there are 4.8 oz of pure gold in Class 7A's gold sand

Given any two numbers which is greater the LCM of the numbers or the GCF of the number? Why?
Natali [406]
The LCM  is the greater.

The GCF  is a factor which  divides in to each number  so can never be equal to the greater number, whereas the LCM is   the greater of the 2 numbers or  a multiple of them

Consider that your profit-maximizing quantity of 500 can be produced at an average cost per unit of $9 and sold for a market pri
timama [110]

Based on the quantity sold and the price, the profit per unit is <u>$5</u> and the total profit is<u> $2,500</u>

The profit made from each unit sold can be found as:

<em>= Market price - Average cost </em>

= 14 - 9

= $5

The total profit would therefore be:

<em>= Profit per unit x Number of units sold </em>

= 5 x 500

= $2,500

In conclusion, the profit per unit is $5 and the total profit is $2,500

Ksju [112]

Answer:

3.162 units

Step-by-step explanation:

First identify the points that undergo transformation

You have;

A = (0,0)   and B =(1,3)

The transformation is T: (x,y)= (x+2, y+1), this means to get the image you add the x coordinate of the object to 2, and the y coordinate to 1.

<u>Finding coordinates of the image points A' and B' </u>

A'= (0+2,0+1) = (2,1)

B'=(1+2, 3+1)=(3,4)

<u>Finding the distance A'B'</u>

The formula for distance d is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

where

x₁=2

x₂=3

y₁=1

y₂=4

d=distance between two points

Applying the formula

d=\sqrt{(3-2)^2+(4-1)^2} \\\\\\d=\sqrt{1^2+3^2} \\\\\\d=\sqrt{1+9} \\\\\\d=\sqrt{10} \\\\\\d=3.162

The distance A'B' is √10 =3.162 units
