Answer:
Below in bold.
Step-by-step explanation:
Amount originally in the cup = amount she drank + amount remaining
= 17 * 4.5 + 148.5
= 76.5 + 148.5
= 225 milliliters.
The time she takes to drink the 148.5 mL = 148.5 / 4.5
= 33 seconds.
So time to drink it all = 17 +33 = 50 seconds.
Is this the image? If so, sorry I can't do this lol
Step-by-step explanation:
14×5=70
8×8=64
(3/70) + (5/64)
= (3×64)+(5×70)
----‐------------------
70×64
= (192+350)/448
=542/448
= 271/224
Answer:
34 mph.
Step-by-step explanation:
Let x be speed of Charlene, then speed of Paul will be x+16 as we are given that Paul is driving 16 mph faster than Charlene.
Let y be distance covered by Charlene, then distance covered by Paul will be 420-y.
Now we will use formula
. Upon using our given information we will get two equation and two unknowns as:


Upon substituting
in 1st equation we will get,

Upon multiplying both sides of our equation by 5 we will get,






Upon substituting y=170 in 2nd equation we will get,


Therefore, Charlene's speed is 34 miles per hour.
a = The cost of the pizza.
b = The cost of the pizza and sales tax.
f(a) = The cost of the pizza.
g(b) = The cost of the pizza and sales tax.
g(f(a)) = The cost of the pizza, sales tax, and delivery fee
