I need to collect 30 stickers. Each bag of crisps contains 3 stickers. How many bags will I need to buy?
soldier1979 [14.2K]
Hey there :)

Let p represent the number of bags to be bought

We need to collect 30 stickers and each bag has 3 stickers

                    3p                                =                        30
                      ↑                                                           ↑
Number of stickers in a bad       Number of stickers to be collected

\frac{3p}{3} = \frac{30}{3}
p = 10

We need to buy 10 bags of crisps to have 30 stickers

Find the area of the trapezoid?
Verdich [7]

Answer: 52.5 units squared

Step-by-step explanation:

The formula to find the area of a trapezoid is, (base1 + base2)/2 * height

So you find out which variable is which

Base 1 = 4

Base 2 = 3

Height = 15

Then plug it into the formula,

(4+3)/2 * 15

Then solve the order of operations

7/2 * 15

3.5 * 15

52.5 is the answer

There is 7 5/9 wood and people took 3 2/15 pieces. How many more pieces are there
GalinKa [24]
What you have to do is subtract 3 2/15 from 7 5/9. You can also use decimals but that doesn't work all the time since the are infinite numbers (you will see what I mean later on) So what you can do is find the improper fraction of each one, and subtract it from each other. It would be 68/9 - 47/15, which would give you a total of 4 19/45. YOU'RE WELCOME :)

Write the equation for a parabola with a focus at (-2,5) and a directrix at y=3.
Fofino [41]

Answer:

(x+2)²=4(y-4)

or y=1/4 (x+2)²+4

Step-by-step explanation:

directrix y=3 and focus (-2,5) to find te equation of parabola we use the equation :

(x-h)²=4p(y-k)

vertex(h,k) : the vertex is half way between the focus and the directrix

y(vertex)=y(focus)+directrix/2

y=5+3/2 ⇒8/2=4

x is the same as the c of the focus =-2

vertex (-2,4)

to find the distance (p) which is the distance between the vertex and focus

p=5-4=1

substitute h=(-2), k=(4) and p=(1) in the equation : (x-h)²=4p(y-k)

(x-(-2)²=4(1)(y-4)

(x+2)²=4(y-4)
