Answer:
if you meant to put 
, then the answer is 7
Step-by-step explanation:
h=-2+32
solve for t
0=-2+32
subtract 32 from both sides
-32=-2
divide both sides by -2
16=
find suare root of 16
4= t-3
add 3 to both sides
7 = t
The volume of a triangular prism is V = 1/2 x a x c x h where a is height of the triangle, c is the base of the triangle and h is the height of the prism.
120 = 1/2 x a x c x h; we write a from the previous equation in terms of c and h thus,
a = 240 / ( c x h)
If the dimensions where halved then a = a/2 ; c = c/2 ; h=h/2
We use the volume formula again and substitute the given values to find the new volume,
V = 1/2 x a/2 x c/2 x h/2
Substitute the previously determined a term,
V = 1/2 x (240/2ch) x c/2 x h/2
We cancel and evaluate the constants therefore the new volume is,
V= 15 cm^3
Answer:
It is arithmetic
Step-by-step explanation:
Using the rule T2-T1
We see that 16-22 is -6
We can also try T3-T2
We see that 10-16 is also -6
Their is a constant common difference and that constant common difference is -6.
Hope that helps :)
Answer:
Step-by-step explanation:
<u>If p is the original price, the markdown price is:</u>
- p - 20% =
- p - p(20/100) =
- p - 0.2p =
- 0.8p
<u>Now, another 20% off:</u>
- 0.8p - 20% =
- 0.8p - 0.8p(20/100) =
- 0.8(p - 0.2p) =
- 0.64p
<u>Answer choices:</u>
- A. 0.2(1p-0.2p)
- B. 0.6p
- C. (1p-0.2p)-0.2p
- D. 0.8p(1p-0.2p)
Correct one is D
Answer:
286 miles / x gallons = 15miles per gallon.
286/15 = x = approximately 19.07 gallons.
