The sum of Ken's, k, and Alan's, a, ages is 62. Ken is 31 years older than Alan.
Which of these systems of equations below best describes the ages of Ken and
Alan?
Answer:
k + a = 62
k = 31 + a
Step-by-step explanation:
Given that:
Sum of ken and Alan's age = 62
Ken is 31 years older than Alan
k + a = 62 - - - (1)
k = 31 + a - - - (2)
Hence, the system of equation which best describes the ages of Ken and Alan are:
k + a = 62
k = 31 + a

Annie measures 9 teaspoons of lemon juice for a recipe. There are approximately 4.9 milliliters in one teaspoon. How many milliliters of lemon juice did Annie measure?
Answer:
44.1 milliliters of lemon juice
Step-by-step explanation:
Number of teaspoons of lemon juice = 9 teaspoons
Amount of milliliters in one teaspoon = 4.9 milliliters
Amount of lemon juice = Number of teaspoons × Amount of milliliters
= 9 × 4.9
= 44.1 milliliters

Mrs. Darby would like to determine if the cafeteria should sell snacks during non lunch periods.
Robert can mow 3 1/2 acres in 3/4 of an hour on his riding lawn mower.
At this rate, how many hours will it take him to mow 8 acres?
Answer:
It will take 1 5/7 hours
Step-by-step explanation:
3/4 of an hour is;
3/4 * 60 minutes = 45 minutes
3 1/2 acres is done in 45 minutes
8 acres will be done in x minutes
Thus, mathematically;
3 1/2 * x = 8 * 45
7x/2 = 360
7x = 2 * 360
7x = 720
x = 720/7 minutes
Let us convert this to hours
That will be;
720/7/60 = 720/(60 * 7) = 720/420 = 12/7
= 1 5/7 hours
A bag has 5 balls: 1 red (R), 1 green (G), 1 yellow (Y), 1 blue (B), and 1 orange

You randomly choose a ball. What is the sample space?
OA. (RG, Y, B, O)
OB. (R,G, Y, B, P)
Oc. (G, )
OD. (R, G, Y, B)
Answer: R,G,Y,B,O
Step-by-step explanation: Sample space is just any and all possible outcomes
The sample space of the given experiment is (R,G, Y, B, O). So option A is the correct one.
What is a Sample Space?A sample space is a set of all the possible outcomes in a random experiment. It is usually denoted by the letter, S.
The subset of the sample space are events.
Given experiment is that you randomly choose a ball from a bag which consists of 5 balls.
Balls are 1 red (R), 1 green (G), 1 yellow (Y), 1 blue (B), and 1 orange (O).
Each ball is of different color.
When you randomly choose a ball, the chosen ball can be any of the colors given.
So sample space = (R,G, Y, B, O)
Hence the required sample space is (R,G, Y, B, O).

What is the length of side BC of the triangle?
Answer:
28
Step-by-step explanation:
x + y = -5
x - y = -7
Answer:
The First one x + y = -5 the x would be -4 and the y would be -1 and for the Second one x - y = 7 The x would be -8 or -9 and the y would be -1 or -2
Step-by-step explanation:
Hope this helps you. :) For the second one -9 - -2 = -7 and -8 - -1 =7 so either one could work.

Find the point of intersection of the lines x-3 = 0 and y-5 = 0.
Answer:
x = 3 and y = 5
Step-by-step explanation:
Given equations are :
x-3 = 0 ....(1)
y-5 = 0 ....(2)
We need to find the point of intersection of the lines.
Add 3 both sides in equation (1).
x-3+3=3
x = 3
Now, add 5 to both sides of the equation.
y-5+5=0+5
y = 5
Hence, the required point of intersection of the lines is x = 3 and y = 5.

A women is twice as old as her daughter . twenty one years ago she was three times her daughter . What is the women's present age?
Answer:
84
Step-by-step explanation:
women=x
daughter=y.
x=2y.
x-21=3(y-21).
2y-21=3y-63.
42=y.
x=84.
Hope this helps plz hit the crown :D
Answer:
Daughter's present age = 42 years
Women's present age = 84 years
Step-by-step explanation:
Daughter's present age = x years
Women's present age = 2*x = 2x
21 years ago:
Daughter's age = x - 21
Women's age = 2x - 21
Women's age = 3*daughter'sage
2x - 21 = 3*(x - 21)
2x - 21 = 3x - 63 {Subtract '2x' from both sides}
- 21 = 3x - 2x - 63
-21 = x - 63 {Add 63 to both sides}
-21 +63 = x
42 = x
Daughter's present age = 42 years
Women's present age = 2*42 = 84 years
Write the equation in slope-intercept form for the line that passes through (5, 4) and (6,-1).
SHOW YOUR WORK
Answer:
y = -5x + 29
Step-by-step explanation:
Slope-Intercept Form of the Line
Given a line of slope m and y-intercept b, the equation of the line can be written as:
y = mx + b
The slope can be calculated by using the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x1,y1) and (x2,y2) are the points through which the line passes.
We are given the points (5,4) and (6,-1), thus:
[tex]\displaystyle m=\frac{-1-4}{6-5}=\frac{-5}{1}=-5[/tex]
Now we use one of the points to find the value of b, for example (5,4):
4 = -5(5) + b
b = 25+4 = 29
Thus, the equation of the line is:
y = -5x + 29

The area is the product of two dimensions, therefore the scale factor is:
A/A' = (b*r*h*r)/(b*h) = r²r² = 18/8r = √9/4 = 3/2 = 1.5The length of the corresponding side will be:

A sample with a sample proportion of 0.4 and which of the following sizes
will produce the widest 95% confidence interval when estimating the
population parameter?
A. 90
B. 60
C. 75
D. 120
The size 60 will produce the widest 95% confidence interval when estimating the population parameter.
What is confidence interval?'A confidence interval is the mean of your estimate plus and minus the variation in that estimate.'
According to the given problem,
IN a sample with n number of people surveyed with a probability of a success of [tex]\pi[/tex] and a confidence level of 1-α , we have the following confidence interval of proportions.
[tex]\pi[/tex] ± [tex]z\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]
In which, z is the z score that has a p value of 1 -(α/2)
The margin of error is:
M = z [tex]\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]
The higher the margin of error, the wider an interval is.
As the sample size increases, the margin of error decreases. If we want, the widest possible interval, we should select the smallest possible confidence interval.
Hence, we can conclude that 60 is the correct answer.
