Answer:
7
Step-by-step explanation:
For the seagull to catch the crab, h(t)=g(t) so:
-16t^2+45=-13t+23 add 16t^2 to both sides
45=16t^2-13t+23 subtract 45 from both sides
16t^2-13t-22=0 using the quadratic equation:
t=(13±√1577)/32, since t>0
t=(13+√1577)/32 seconds
t≈1.65 seconds (to nearest hundredth of a second)
And the height that this occurs using either original equation is:
h((13+√1577)/32)≈1.59 ft (to nearest hundredth of a foot)
Answer:
<u>4</u>
Step-by-step explanation:
Hi so basically you just convert the inches to decimals so
0.5 x 0.5 x 0.25 = 0.0625
Use a calculator to convert 0.0625 into fraction which is 
Multiply
by 3 = 
Then multiply
by
= 4
Soo that was probably very confusing, but I hope it helps! :)
Plz click the Thanks button, I rrly appreciate it!
Answer:
sold 120 chocolate bars
sold 140 peanut butter bars
Step-by-step explanation:
x = peanut butter bars
y = chocolate bars
x + y = 260, total lbs
0.25x + 0.30y = 71, money
solve double variable equation
multiply -4 on both sides for 2nd equation
-x + -1.2y = -284
add both equations together
-0.2y = -24
y = 120
x = 260 - 120
x = 140
sold 120 chocolate bars
sold 140 peanut butter bars
