You can remember as "Please Excuse My Dear Aunt Sally" or PEMDAS.
In this question: 5x5+2.8÷2.2+3.3= 25+16÷4+3=25+4+9=38
The original photo is 4 by 6
The ratio of that is 4/6 or 2/3
Since the “wide” is extended to 12, you simply compare the ratio as 4/6=12/x and solve for x. Cross multiply and you should get 18 inches tall
Ok so on the y intercept go to the 12th point then for the -x go to the right once and down then plot the point keep doing that for as long as u need then draw a line connecting all the dots
Answer:
b
Block B has the greatest density.
Step-by-step explanation:
density = mass/volume
volume = length × width × height
All blacks have the dimensions 7 cm by 3 cm by 1 cm, so the 3 volumes are equal.
Since density = mass/volume, and the volumes are equal, the block with the highest mass has the highest density.
Since all the masses are different, all densities are different.
Answer: Block B
