Answer:6
Step-by-step explanation:
If we know that the formula of a rectangular prism is length * width * height, and we know the height and width are 7 and 9, the length is the only thing that is left. The volume is 378, and so now we have:
length * 7 * 9 = 378. Dividing the 9 and 7, we get 378/(9*7). The length is 6.
Answer:
SA = 76 yd²
Step-by-step explanation:
Use the formula given:
- SA = 2(4)(2) + 2(4)(5) + 2(2)(5)
- SA = 16 + 40 + 20
- SA = 76
The units are yards²
SA = 76yd²

Answer:
y=-1/3x
Step-by-step explanation:
We use the linear equation of y=mx+c
Y=c
We know that y=0 and that m=-1/3, therefore we plug it in the formula.
y=-1/3x+0
y=-1/3x
Answer: 1
Step-by-step explanation:
First you need to multiply 3 x 3 (9), because that's all 3 squared means.
Now the equation should be 9x-6x+3=0
Next we need to combine like terms. Do 9x - 6x which should give you 3x
Now your equations should be 3x+3=0
Now for the somewhat harder part...
Under the three (the one without the x) write -3 and under the zero write the same thing. the +3-3 cancels out so just put a line or something across it.
0-3= -3
so now you should have...
3x=-3 ignore the 3x, at this point it's useless in getting the answer because it would cancel out.
-3 divided by -3 is 1 because a negative (-) divided by a negative (-) equals a positive (+).
The answer should be x = 1
Answer:
tan (A) = 1
Step-by-step explanation:
When sine and cosine are equal to each other, they have the same value. We know that tan (A) = sin (A) / cos (A). If sin (A) and cos (A) are the same, and any number divided by itself equals 1, the final answer must be tan (A) = 1.
