Please help me!!!!!!

Mathematics
1 answer:
Elodia [21]3 years ago
8 0

Answer:

t=5.25x

Step-by-step explanation:

since X equals the number of egg cartons sold then we would have to multiply that by how much one egg carton costs (5.25$ each)

so if they sold 3 egg cartons the equation would be t=5.25*3.

(putting a variable next to a number means your multiplying it)

I hope I explained that clearly enough :P

To the nearest tenth of a precent, 78 is what precent of 82
forsale [732]

Answer:

95.1

Step-By-Step Explanation

78:82*100 =

(78*100):82 =

7800:82 = 95.12

Now we have: 78 is what percent of 82 = 95.12

Question: 78 is what percent of 82?

Percentage solution with steps:

Step 1: We make the assumption that 82 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100%=82

Step 4: In the same vein, x%=78

Step 5: This gives us a pair of simple equations:

$100\%=82(1)

$x\%=78(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100% over x% = 82 over 78

Step 7: Taking the inverse (or reciprocal) of both sides yield

x% over 100% = 78 over 82

x = 95.12%

Therefore, 78 is 95.12% of 82

1.) A projectile launched straight up into the air with an initial velocity of 20 meters per second from a height of 10 meters.
Dafna1 [17]
Hello,

I have just answered the question


gravity on earth :g=9.81 m/s²

h(t)=-\frac{g*t^2}{2}+v_{0}*t+h_{0}
9.81/2≈4.9
v_{0}\ is\ initial\ speed
h_{0}\ is\ initial\ height

Answer 1


2)
h(t)=-4.9*t²+20*t+10

To hit the ground ht(t)=0
==> -4.9*t²+20*t+10=0
Δ=20²+4*4*10=560=23,6643...²

t=(-20-4√35)/(-4.9*2)=4,4555...(s)

t=(-20+4√35)/(-2*4.9)=-0,37391... to exclude (time must be >0)
