Answer:
t=6
Step-by-step explanation:
ground height = 0
(are you sure your formula is correct? isn't it - 16t²?)
if h=16t² +64t+192 is true then
16t² +64t+192 = 0
t² + 4t + 12 = 0
t = (-4 ± √(4² - 4*12)) / 2*1 = (-4 ± √-32) / 2 = -2 ± 2√-2
There is no solution of t
if it is h= - 16t² +64t+192
0 =- 16t² + 64t + 192
t² - 4t - 12 = 0
(t + 2) (t -6) = 0
t should be positive
t = 6 sec

Solve for y.
-2+2(6y+7)=9y
y=
Answer:
y=-4
Step-by-step explanation:
Distribute:
−2+12+14=9
Add the Numbers:
12+12=9
Rearange the Terms:
12+12=9
Subtract 12 from both sides:
12+12−12=9−12
12=9−12
Subtract 9y from both sides:
12−9=9−12−9
3=−12
Divide both sides of the equation by the same term:
3y/3=12/3

80 is 5% of what number?
Answer:
1600
Step-by-step explanation:
1600 x 0.05 = 80
or
80 / .05 = 1600
Answer:
1600
Step-by-step explanation:
80 = 5 / 100 * x
80 * 100 = 5 * x
80 * 20 = x
x = 1600

How do you do and simplify 8/9 + (-5/6)
Over
1/6
These are fractions btw
Answer:
5 89/100
Step-by-step explanation:
If there is a negative sign in the denominator of any of the fractions, shift the negative sign(s) to the numerator:
-5/6=5/6
Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:
5/6÷1/6=5/6×6/1
Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
(5 × 6) / (6 × 1) =30 / 6
The Greatest Common Factor (GCF) of 30 and 6 is 6. The result can be simplified by dividing both the numerator and denominator by 6.
30/6= (30 ÷ 6) / (6 ÷ 6) = 5
therefore..
-5/6÷1/6= 5
qns
8/9 + {(-5/6) / (1/6)} = 8/9 + 5 = 5 8/9
Combine the whole numbers and fractions together:
(0 + 5) + (8/9+0)
The whole numbers part is:
0 + 5 = 5
For the fractions part:
The Least Common Multiple (LCM) of 9 and 1 is 9. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:
8/9+0=8/9+0 × 9=8/9+0/9
Now that the fractions have like denominators, add the numerators:
8/9+0/9=(8+0)/9=8/9
Put the whole number and fraction together:
5 +8/9=5 8/9
The result is:
8/9+5=5 8/9

Answer:
1. 45
2. 6
3. 120
4. -20
Step-by-step explanation:
1. First you take 10-1=9x5=45
2. First you take 4+4=8 then 48/8=6
3. First you take 10-8=2x4=6x20=120
4. First you take 5-3=2-4=-2/40=-20
I hope this helped!Use the frequency table below to find the average score students earned on a
test.
Score
Frequency

So you would multiply the frequency to the score because finding the average is adding everything. then you add those numbers up. then, add up the frequency to get your divisor. After you divide you take your number and round to the hundreth or tenth

Answer:
The equation is y = -2x + 12.
Drag the symbol or variables y, =, -2 , x, +, 12
Step-by-step explanation:
Slope intercept form: y = mx + b.
Solve 4x + 2y = 24 for "y"
4x + 2y = 24
2y = -4x + 24
2/2y = -4/2x + 24/2
y = -2x + 12

miles per hour
Answer:
The average speed here is 60 mph.
Step-by-step explanation:
We need to express the unit rate here. That's the speed, which is defined as (distance) / (time):
1 mile
speed s(t) = ----------------
t (min)
We need to convert the unit of time (min) to the new unit of time (hrs):
1 mile 60 min
speed s(t) = --------------- * -------------- = 60 miles/hr = 60 mph
t (min) 1 hr
The average speed here is 60 mph. This is not dependent on time, t, so we cannot calculate s(10) or s(12). Because of this, s(t) = 60 mph. The distance traveled in t hours is d(t) = s(t)*t.
