Answer:
<u>The number of pens = 120 and the number of pencils = 200</u>
Step-by-step explanation:
Let the number of pens x, and the number of pencils is y
the cost of one pen $1, and the cost of one pencil $0.5
The cost of the whole purchase was $220
1 * x + 0.5 * y = 220
x + 0.5 y = 220 ⇒ eq.(1)
there were 80 more pencils than pens
y - x = 80 ⇒ eq.(2)
from eq.(2) x = y - 80
By substitution with x from the last equation at eq.(1)
∴ (y - 80) + 0.5 y = 220
1.5y = 220 + 80 = 300
y = 300/1.5 = 200
x = y - 80 = 200 - 80 = 120
<u>So, the number of pens = 120 and the number of pencils = 200</u>
Answer:
<h2>5/36</h2>
Step-by-step explanation:
This is a probability problem, so let us treat it as such.
the sample space for the die is =(1,2,3,4,5,6)
the sample size is =6
For the spinner the sample space is
red=2
pink=1
white=3
the sample size for the spinner is =6
The probability of rolling a number greater than 1 and then the spinner stopping at a pink section
=Pr(no>1)*Pr(spinner=pink)
no>1= 2,3,4,5,6
no>1=5
pink=1
hence
=5/6*1/6
=5/36
<h2>The probability is 5/36</h2>
Answer: 14 inches
Step-by-step explanation:
Given the following :
James wants to cut a floor tile in the shape of a trapezium with the following dimension :
Top base = 12 inches
Bottom base = 16 inches
To obtain the medan, we take the average of the two bases :
(top base + bottom base) / 2
(12 inches + 16 inches) / 2
28 inches / 2
= 14 inches.
