Answer:
<u>In 3 months</u>
Step-by-step explanation:
Henrik buys at 40 cards/month.
Kharif sells at 20 cards/month, from a starting collection of 180 cards.
At x months, Kharif will have 180-(20 cards/month)(x months)
At x months, Kenrik will have 0 + (40 cards/month)*x {We must assume he starts with 0 cards, since no information is given.]
We want to know the nmonths until Both have the same number, so set their equations equal to each other:
180-(20 cards/month)(x months) = 0 + (40 cards/month)*x
180 = x(40 cards/month + 20 cards/month)
180 = x(60 cards/month)
x = 3 months
In 3 months, both will have 120 cards
Answer:8/10
Step-by-step explanation
There are 8 t shirts and 10 shirts so there will be a 8 out of ten Vance of wearing a short sleeve shirt
Ratio of length to width of a map = 8:5
Length of the map = 32 inches
Let the width of the map = x inches
So,
Length : Width = 8 : 5
32 : x= 8: 5
x = 5/8 * 32
x = 20 inches
So, the width of the map is 20 inches
Given:
The height of the the tree from where the tree was broken = 13 ft
The distance from the foot of the tree to the broken top = 36 ft
To find the height of the tree.
Formula
By Pythagoras theorem we get,
h² = l²+b²,
where, h be the hypotenuse
b be the base and
l be the other side of the triangle along the right angle.
Now,
Putting, l =13 and b = 36 we get,
or,
or,
or,
or,
Therefore,
The height of the tree is about = 13+38.3 ft = 51.3 ft
Hence,
The height of the tree is about 51.3 ft.
First step is to add like terms, so 6q plus q equals 7 q then what's left is the 8, therfore you answer is 8+7q
