Answer:
The first skier goes at a speed of 11 kilometers per hour, while the second does it at a speed of 18 kilometers per hour.
Step-by-step explanation:
Given that two skiers are 43.5 kilometers apart and head towards each other, and they meet in 1.5 hours, if the second skier is 7 kilometers per hour faster the other, to find the speed of each skier the following calculation must be performed:
43.5 / 1.5 = 29
29 - 7 = 22
2/22 = 11
11 x 1.5 + 18 x 1.5 = X
43.5 = X
Thus, the first skier goes at a speed of 11 kilometers per hour, while the second does it at a speed of 18 kilometers per hour.

Ms. Jankowski’s art class has a total of 35 students enrolled. Seven of the thirty-five students are girls. What percentage of the class is made up of boys? *
Answer:
80% of the class is made up of boys
Step-by-step explanation:
7/35 are girls, which means, 28/35 are boys (35 - 7)
To find the percentage, you divide 28 by 35
28/35 = 0.8 or 80%

8. Which of the following correctly multiplies f(x) x g(x) if f(x) = 3x-1 and g(x) = 2x + 1?
A) f(x) x g(x) = 6x2 + x + 1
B) f(x) x g(x) = 5x
C) f(x) x g(x) = 6x2 + x-1
D) f(x) x g(x) = 5x2 + x-1
Answer:
C) f(x) x g(x) = 6x2 + x-1
Step-by-step explanation:
Multiplication of functions:
Two multiply two polynomial functions, we apply the distributive property(multiply each two terms and add).
In this question, we have that:
[tex]f(x) = 3x - 1, g(x) = 2x + 1[/tex]
The multiplication is:
[tex]f(x) \times g(x) = (3x - 1)(2x+1) = 3x*2x + 3x*1 -1*2x -1*1 = 6x^2 + 3x - 2x - 1 = 6x^2 + x - 1[/tex]
The correct answer is given by option C.

Given angle DEF : angle RST, find the scale factor.
The scale factor is the bigger over the smaller, so [tex]\frac{4}{3}[/tex] is the scale factor.
To find x, we just use a proportion Biggest to Smallest:
[tex]\frac{4}{3}=\frac{16}{x}[/tex]
4x = 48
x = 12
What is the greatest common factor of the numerator and denominator in the expression: 6x+2x^2/9x^2+3x^3?
A. 3+x
B. 3x+x^2
C. x
D. 2/3x
Answer:
A) 3+x
Step-by-step explanation:
6x + 2x² / 9x² + 3x³
2x(3 + x) / 3x²(3 + x)
What is the value of the function f(x)= 1/4 x-3 when x=12
Answer:

The difference between two positive integers is 4. If the smaller is added to the square of the larger, the sum is 52. Find the integers.
Answer:
The integers are 7 and 3
Step-by-step explanation:
if you put x as smaller number and y as bigger number you can write two equations:
x+y^2=52 and y-4=x
In the first polynomial, y can either equal 7 or -8, but the number has to be positive, so it's 7
y-4 to get x, plug 7 in and you get x=3
y=7 and x=3
Answer:
7 and 3
Step-by-step explanation:
We will let x equal the larger one
y will be the smaller one
We can write the two equations
x-y=4
y+x²=52
We will solve this through substitution
we will take the first equation and add y to moth sides
x=4+y
we then substitute this into our second equation
y+(4+y)²=52
distribute the square
y+8y+y²+16=52
y²+9y-36=0
Factor this
(y-3)(y+12)=0
Which means that y is either 3 or -12 but because it said that both numbers are positive we can reject the negative 12 (which means that y is 3)
Plug in y=3 into our first equation
x-3=4
x=7
you owe $1,000 to a credit card company with 18% interest rate that will be compounded daily assume that there are no late fees and you knew not pay for one year how much will you owe after one year
9514 1404 393
Answer:
$1197.16
Step-by-step explanation:
The future value is given by ...
FV = P(1 +r/n)^(nt)
for principal P earning annual rate r compounded n times per year for t years
Your balance due will be ...
FV = $1000(1 +0.18/365)^(365·1) ≈ $1197.16
You will owe $1197.16 after 1 year.

Step-by-step explanation:
A study will be conducted to investigate whether there is a difference in the mean weights between two populations of raccoons. Random samples of raccoons will be selected from each population, and the mean sample weight will be calculated for each sample.
Which of the following is the appropriate test for the study?
A. one-sample zz-test for a population proportion
B. A one-sample tt-test for a population mean
C. A two-sample tt-test for a difference between sample means
D. A two-sample tt-test for a difference between population means
E. A two-sample zz-test for a difference between population proportions
Answer:
D. A two-sample t-test for a difference between population means
Step-by-step explanation:
Since in the question it is mentioned that there would be the random samples taken from each population of raccons and the weight of the mean sample would be determined for each kind of sample
So here the test for the study that should be considered is two sample t-test so that it would create a difference between the population means
Hence, the option d is correct

On test 7, Josue's score dropped back from 98 to 85. What is the percent decrease?
Answer:
13 %
I hope it's correct.
Step-by-step explanation:
initial marks (o) = 98
final marks (m) = 85
rate (r) = ?
Now,
r =
[tex] \frac{o - m}{o} \times 100percent[/tex]
= ((98-85)/98)x100%
=13.26%
Evaluate :
