Alright! I've seen quite a few of these so I thought I'd get them out of the way and help you out! :).
Direct variation is simple. The formula you'll use to find the constant K is as follows:
y = kx
Once you've established your formula you simply plug in:
.3 = (k)(.6)
Then you solve for k by dividing both sides by (.6) thus getting:
(.3/.6) = k OR (1/2) = k
Your direct variation equation is your standard formula with only K plugged in:
y = (1/2)x
Answer:
Im sorry but I am not really sure myself ! I hope you find or found your answer already !
Step-by-step explanation:
Answer:
x=1 y=1
Step-by-step explanation:
Let's use the elimination method.
3x+4y=7
2x-y = 1 (multiply both sides by 4)
8x-4y=4
3x+4y=7
(add both equations together)
11x=11
x=1
Plug x=1 into either of the equations
2(1) - y=1
2-y=1
2=1+y
y=1
Answer:
150 degrees
Step-by-step explanation:
75 -----> 75 out of 360
360-75=285
285-75 will be divided by 2
210 divided by 2 equals 105
105 is the measure of the angle I think (lmk if its wrong)
Volume of the prism = 75 cubic feet
Solution:
The image given is a rectangular prism (or) a cuboid.
Area of base = l × b = 25 square feet
Height of the prism = 3 feet
Volume of the prism = l × b × h
= (l × b) × h
= 25 × 3
= 75 cubic feet
Volume of the prism = 75 cubic feet
Hence, the volume of the prism is 75 cubic feet.
