<span>1st one: x, 2nd wud b : x+2
if its sum is 56
means:
x+ (x+2) = 56
2x = 56 -2
x= 54/2
x= 27
27 is the first odd number and the second is 27 + 2 i.e. 29
------------------------
sum of two numbers is 72
let smaller: x
larger: 4+x
its sum:
(4+x) + x = 72
4+2x=72
x= 68/2
x= 34
smaller is 34 and the larger is 34 + 4 = 38

Answer:
<h3>
She reaches her maximum height after 0.25 seconds</h3>
Step-by-step explanation:
The question is not properly structured and the equation is also incorrect. Here is the correct question.
You and some friends went to a haunted house on Halloween. The mummy scared one friend so much that she jumped into the air! The equation h= -4t²+ 2t models her jump where h is her jumps height in feet t seconds after the mummy scares her. When did she reach her maximum.
Give the equation h= -4t²+ 2t that models my friend jump where h is her jumps height in feet t seconds, At maximum height, her velocity will be zero i.e
Vmax = 0m/s
Velocity is the rate of change in distance of a body i.e V = dh/dt
Given h= -4t²+ 2t
V = dh/dt = -8t+2
Since v = 0m/s
0 = -8t+2
-8t = -2
t = -2/-8
t = 0.25 secs
She reaches her maximum height after 0.25 seconds
Answer:
15%
Step-by-step explanation:
17/20 the 17 is the part, and the 20 is the whole
17/20 = x/100
cross multiply
17*100= 1,700 divide by 20
=85
The price reduced to 85% the original price, but to find out how much it changed, you have to subtract the part from the whole meaning
100% - 85% = 15%
A manipulated variable<span> is the independent </span>variable<span> in an experiment. It's called “</span>manipulated<span>” because it's the one you can change. In other words, you can decide ahead of time to increase it or decrease it. In an experiment you should only have one </span>manipulated variable<span> at a time</span>
If you are talking about a cylinder than your answer would be 111.61
if you are talking about a cone then the answer is 56.79
