8 x 16 = 128, so its considered as the first side of the room blueprint.
4 x 8 = 32. 128 / 32 = 4. 4 is your answer!
Answer:
30 Pencils
Step-by-step explanation:
If Patrick has 2 pencils, and Phyllis has 7 more than him, phyllis has 9 pencils.
But Phyllis has 12 less pencils than Nadine, we can find how many pencils Nadine has by adding 7+12=19
Nadine has 19 pencils
Now we add these all together
2+9+19= 30
All together, they have 30 pencils.
Hope this helps! Have a great rest of your day! :)
Answer:
h = -0.0166t^2 + 30.
Step-by-step explanation:
The graph of the flight is a parabola which opens down and is symmetrical about the y axis, passes through the x axis at -42.5 and 42.5 and has a vertex at (0, 30).
So we have -a(t^2) + 30 = 0 where t is the time
(42.5)^2 * -a = -30 (42.5 as its 1/2 * 85).
a = 30/2806.25
= 0.01661
So the equation is height h = -0.0166t^2 + 30

Answer:
x = 12/7
Step-by-step explanation:
in order to solve this formula x/4 + x/3 = 1
<u>solutio</u>n
x/4 + x/3 = 1
the first step to do is to take lcm of the left hand side
[3(x) + 4(x)] /12 = 1
[4x +3x]/ 12 = 1
7x/12 = 1
cross multiply
7x/12 = 1
7x = 12 × 1
7x = 12
divide both sides by 7
7x/7 = 12/7
x = 12/7
