Hi there, we divide 320 miles in 8 hours and we get 40. Now, we divide 230 miles in 5 hours and we get 46. Therefore, Maurice drove the faster rate.
Answer:
See below ~
Step-by-step explanation:
There are 4 possible solutions :
<u>m = 4</u>
<u>m = 5</u>
<u>m = 6</u>
<u>m = 7</u>
Let x and y represent the two numbers that add up to 24.
x + y = 24
=> y = 24 - x
The product of the two numbers is P = x*y = x*(24 - x) = 24x - x^2.
To maximize the product P, solve P' = 0 for x.
P' = 24 - 2x
24 - 2x = 0
=> x = 12
Also P'' = -2 which is negative
for x = 12
The product when x = 12 is 12*12 = 144

The value of the expression (6¾) × -11.5 is; -77⅝
We want to find the value of;
(6¾) × -11.5
Let us change 6¾ to improper fraction to get;
27/4
Also,let's change -11.5 to an improper fraction to get; -115/10
Thus;
(6¾) × -11.5 = 27/4 × -115/10
>> (-115 × 27)/(40)
>> 3105/40
>> -77⅝

Answer: you will use the cosine rule
Step-by-step explanation:
x^2=11^2+8^2-2(11)(8)xcos(16)
x^2=185-169.18
x^2=15.8
Take square root
x=3.96 or 4
