Carlos and Maria drove a total of 233 miles in 4.4 hours. Carlos drove the first part of the trip and averaged 55 miles per hour

Mandarinka [93]

Let x - hours Carlos drove ; Let y - hours Maria drove

Equation 1: x + y = 4.4
x = 4.4 - y

Equation 2: 55x + 50y = 233
55(4.4 - y) + 50y = 233
242 - 55y + 50y = 233
-5y = 233-242
-5y = -9
y=9/5 or 1.8 hours Maria drove

To find time Carlos drove:
x=4.4 - 1.8
x = 2.6 hours

Find the remainder when f(x) is divided by (x - k). f(x) = 8x4 + 7x3 + 5x2 - 5x + 35; k = 4

Slav-nsk [51]

Using the remainder theorem, evaluating the function for k will be the same value as the remainder.
8(4^4) + 7(4^3) + 5(4^2) -5(4) + 35 =
2048 + 448 + 80 + - 20 + 35 =

in a class of 25 students 8% of the students play on a softball team how many students play on the softball team

Alla [95]

2 students play on the softball team

Solution:

Given that in a class of 25 students, 8 % of students play on a softball team

To find: Number of students play on softball team

Total number of students in class = 25

8 % of students play on a softball team means that 8 % of total students play on softball team

Therefore, number of students play on softball team is given as:

$\rightarrow 8 \% \text{ of } 25\\\\\rightarrow 8 \% \times 25\\\\\rightarrow \frac{8}{100} \times 25\\\\\rightarrow \frac{8}{4} = 2$

Thus 2 students play on the softball team
