on a lake, Carol rowed a boat for 1/8 mile. Then luke rowed the boat for 3/8 mile. how far did carol and like row in all? simplify the answer if possible help pls
Answer:
[tex]Total = \frac{1}{2}[/tex]
Step-by-step explanation:
Given
[tex]Carol = \frac{1}{8}[/tex]
[tex]Luke = \frac{3}{8}[/tex]
Required
How far did they row together
To do this, we simply add the distance they both covered.
[tex]Total = Carol + Luke[/tex]
This gives;
[tex]Total = \frac{1}{8} + \frac{3}{8}[/tex]
Take LCM
[tex]Total = \frac{1+3}{8}[/tex]
[tex]Total = \frac{4}{8}[/tex]
Simplify
[tex]Total = \frac{1}{2}[/tex]
Hence, they both rowed 1/2 mile

Step-by-step explanation:
1
1.6
0.4
2 . 0
Answer:
y = 1.6
Step-by-step explanation:
u are finding what y equals so u set up ur equation like this
y + 0.4 = 2
- 0.4 = - 0.4
----------------------
subtract 0.4 on both sides u get 1.6
and now ur left with y so y = 1.6 ! pretty ez right

Answer:
The second, fourth and fifth answers are correct, as they all have a slope of 2.
Step-by-step explanation:
To find the answer to this, all you need to do is see which equations have the same coefficient to x.
In this case, the second, fourth and fifth one all have an x coefficient of 2, which means that those three lines are parallel.

Use either Gaussian elimination or Gauss-Jordan elimination to solve the given system or show that no solution exists. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, use t for the parameter.) x1 + x2 + x3 = 0 x1 + x2 + 9x3 = 0
Answer:
x1 = t, x2 = -t and x3 = 0
Step-by-step explanation:
Given the system of equation
x1 + x2 + x3 = 0 .... 1
x1 + x2 + 9x3 = 0 .... 2
Subtract both equation
x3 - 9x3 = 0
-8x3 = 0
x3 = 0
Substitute x3 = 0 into equation 1
x1 + x2 + 0 = 0
x1+x2 = 0
x1 = -x2
Let t = x1
t = -x2
x2 = -t
Hence x1 = t, x2 = -t and x3 = 0

Researchers for the National Institute of Child Health and Human Development studied 208 infants whose brains were temporarily deprived of oxygen as a result of complications at birth. These babies were subjects in an experiment to determine if reducing body temperature for three days after birth improved their chances of surviving without brain damage. What is the population
Answer: All infants
Step-by-step explanation:
In statistics,
Population is a term that is used to represent the largest group sharing similar charcteristic from the researcher's point of view.
A sample is a subset of the population.
Here, a sample is collected of infants which were subjects for the study.
Objective of study: To check if reducing body temperature for 3 days after birth improved their chances of surviving without brain damage.
Here, the population of interest is "All infants".

Andrew calculates that 40% of 50% of x is equal to 20% of 30% of y, where x ≠ 0. Which of the following is true?
Answer:
y=8x/3
Step-by-step explanation:
In this question the options are not given clearly but the value of x in terms of y can be written as
[tex]\rm \bold{x = \dfrac{3}{10} \times y }[/tex]
According to the given situation in the question
Andrew calculates that 40% of 50% of x = 20% of 30% of y
Given that x ≠ 0
The given condition can be formulated in the form of equation (1) as follows
[tex]\rm 40\% \times 50\% \times x = 20\% \times 30\%\times y ........(1)\\[/tex]
Equation (1) can be further solved to get
[tex]\rm \dfrac{40}{100} \times \dfrac{50}{100} \times x = \dfrac{20}{100}\times \dfrac{30}{100}\times y[/tex]
[tex]\rm 2/5\times (1/2)\times x = (3/50)\times y[/tex]
[tex]\rm x /5 = 3/50 \times y \\x = \dfrac{3y}{10}[/tex]
In this question the options are not given clearly but the value of x in terms of y can be written as
[tex]\rm \bold{x = \dfrac{3}{10} \times y }[/tex]

What expression in terms of x can be used to represent the area of parallelogram PQRS?
There is a parallelogram PQRS in which the diagonal PR and the diagonal QS bisect each other into two equal parts at right angle . Each part of both the diagonals has a length 5x.
Answer:
[tex]Area = \frac{25x^2}{2}[/tex]
Step-by-step explanation:
Given
Shape: Parallelogram
[tex]PR = 5x[/tex]
[tex]QS = 5x[/tex]
[tex]\theta = 90[/tex]
Required
Find the area of the parallelogram
Because we were given the measure of the diagonals, the area is:
[tex]Area = \frac{1}{2} * PR * QS * \sin \theta[/tex]
This gives:
[tex]Area = \frac{1}{2} * 5x * 5x * \sin \ 90[/tex]
[tex]Area = \frac{1}{2} * 5x * 5x * 1[/tex]
[tex]Area = \frac{1}{2} * 25x^2[/tex]
[tex]Area = \frac{25x^2}{2}[/tex]

Step-by-step explanation:
multiply the denominator and numerators. If it is needed to be simplified,
find the gcf of 5 and 60. That would be 5. So divided 5/60 by 5. This would be your final answer of 1/12.
