1) 200 candies

15% of my candies were strawberry candies. I had 30 strawberry candies. How many candies did i have?

-----

Let "x" be the number of candies.

----

Equation:

0.15x = 30

x = 30/0.15

---

Multiply numerator and denominator by 100 to get:

------------------

x = 3000/15

----

x = 200

---------------------------------

2) 146 STUDENTS

27%*T=54, So T=200.

So 200-54=146 Students passed the test.

---------------------------------

3) She got a 20% discount (or 80% discount). (Work shown for 80%).

First you have to find out how much Mandy paid. So from 15000 you will subtract 3000. 15000-3000=12000.

Next you need to set up your equation. . You then have to cross multiply. So 100 times 12000, 100*12000=1200000. And 15000 times x is 15000x. Finally you divide both sides by 15000. And 1200000 divided by 15000 is 80. X=80

Step-by-step explanation:

Find the x-intercept and the y-intercept of the following equation:<br> 4x - 6 y = 12
Dafna1 [17]
The answer is:
X int- 4
Y int- -12

Explanation:
You must subtract 12 from both sides
4x-6y-12=0

Add -6y to both sides

4x-12=y

Plus into y=mx+b

Y=4x-12

how many 1 1/2 centimeter cubes can fit into a rectangular prism that has a length of 12 centimeters , a width of 6 centimeters
VLD [36.1K]

The long, straightforward, brute-force way to slog through the problem:

The prism is 12cm x 6cm x 9cm.

Volume of the prism = (12 x 6 x 9) = 648 cm³

Volume of each little cube = (1.5 x 1.5 x 1.5) = 3/375 cm³

Number of little cubes that fit into the prism =  (648 cm³) / (3.375 cm³) = <em>

                                                                                     192 of them</em>


=============================================

The elegant but almost equally long way to master the problem:

The prism is 12cm x 6cm x 9cm.

If each dimension of your measuring cubie is 1.5cm,
then the prism measures

     (8 cubie lengths) x (4 cubie widths) x (6 cubie heights) .

Its volume is  (8 x 4 x 6) = <em>192 measuring cubies</em>.
