-4 cause a negative plus a negative is a negative
Answer:
Wow, I'm learning this in class right now lol, the answer is C, 42cm cubed.
Step-by-step explanation:
The formula for finding volume fo 3d shapes is area of base x height/length.
In this problem, they give you both of those. 14 x 3 = 42, so the answer is C.
Hope this helped! If it did, please give me brainliest! It would help a lot! Thanks! :D
There are 17 people. 3 Times 5 = 15 + 2 = 17
5.25 pounds of one alloy containing 45% copper and 36.75 pounds of 69% copper is used to make 42 pounds of 66% copper
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the amount of 45% copper and y represent the amount of 66% copper needed to make 42 pounds of a third alloy containing 66% copper. Hence:
x + y = 42 (1)
Also:
0.45x + 0.69y = 42(0.66) (2)
This gives:
x = 5.25, y = 36.75

this is because probability is equal to favourable outcome/total outcome. in this case, favourable outcome is the outcome that is asked in the question and total outcome is all the possibilities
