I’m assuming you mean there are 5 rows which are equal, and use all the 115 photos. If this is the case then 115/5 is 23 photos per row.
11m
The area of a triangle is bh/2. If we know the height (8m), we can plug it into a=bh/2 for a=8h/2 or a=4h or a/4=h
Since we know the area (44m^2), we can put that in for 44/4=h or h=11 metres.
Answer:
B is all about addition and multiplication
Answer:
160
Step-by-step explanation:
This is basically saying "8 is 5% of what number (total)"?
<u>Note:</u> 5% in decimal is 5/100 = 0.05
When translating a word statement into algebra, we need to note that "is" means "equal" and "of" means "multiplication".
Let's translate <u>"8 is 5% of what number (total)"</u> (letting total number of coins be n):
8 = 0.05 * n
<em>solving, gives us:</em>
<em>8 = 0.05*n</em>
<em>n = 8/0.05 = 160</em>
<em />
<em>Hence, total number of coins Mia has is 160</em>
