Complete question :
Ray starts walking to school at a rate of 2 mi/h. Ten minutes later, his sister runs after him with his lunch, averaging 6mi/h. Determine take it takes for sister to catch up
Answer:
5 minutes
Step-by-step explanation:
Ray's rate = 2mi/ hr
Time walked before sister starts = 10 minutes = (10/60) = 0.16667 hours
Hence, distance already covered = (rate * time) = (2 * 0.16667) = 0.3333 miles
To catchup :
Let t = Time taken to catch ; At t, distance covered must be the same ; thus ;
0.3333 + (2 * t) = 6 * t
0.3333 + 2t = 6t
0.3333 = 6t - 2t
0.3333 = 4t
t = 0.3333 / 4
t = 0.0833333 hours
t = 0.0833333 * 60 = 5 minutes

Which of the following is a radical equation?
O x^3 - 13
0
X+ 3 = 13
O x + 3 = 13
O X+3= 13
Answer: The Third one (C)
Step-by-step explanation:
You subtract 3 both sides
Simplify sqrt x= 10
square both side: x = 100
So thats what makes it radical equation.

Answer question 3. Please show you’re work.
Answer:
a. x = 11
b. 1 = 38
c . 2 = 55
Step-by-step explanation:
Here, we want to find the values of the marked angles
The two add up to give a right angle
Thus;
5x + 3x + 2 = 90
8x = 90-2
8x = 88
x = 88/8
x = 11
m1 = 3x + 5
substitute for x
m1 = 3(11) + 5 = 38
m2 = 5x
= 5(11) = 55

1/3 + a = 5/4
What does the a equal?
Answer:
1/3 + a = 5/4 = 4/15
Answer:
[tex]a = \frac{11}{12}[/tex]
Step-by-step explanation:
In order to find the value of a we just solve the equation as follows....
[tex]\frac{1}{3} + a = \frac{5}{4} \\[/tex]
[tex]a = \frac{5}{4} - \frac{1}{3}[/tex]
[tex]a = \frac{15}{12} - \frac{4}{12}[/tex]
[tex]a = \frac{11}{12}[/tex]
Does 5 mm , 12 mm , and 17 mm form a right triangle
Answer:
The measurements do not form right angled triangle.
Step-by-step explanation:
Given lengths are 5 mm, 12 mm and 17mm
The longer leg forms the hypotenuse of the right angled triangle.
Using Pythagorean theorem;
[tex]a^2+b^2=c^2\\(5)^2+(12)^2=(17)^2\\25+144=289\\169\neq 289[/tex]
Therefore,
The measurements do not form right angled triangle.
Q2
A car travels at 72 mph for 3 hours and 40 minutes.
How far has it travelled?
miles
[2]
8
Answer:
264 miles
Step-by-step explanation:
Let's convert 3 hours and 40 minutes into hours first.
Recall that 1 hour = 60 minutes.
Therefore 40 minutes = 40/60 hours = 2/3 hours.
The car travelled 3 and 2/3 hours in total.
Recall that distance = speed times time.
The car has travelled 72 x 3 2/3 miles = 264 miles.
will someone please tell me what I got correct and what I got incorrect
Answer:
all correct
Step-by-step explanation:
Answer:
What you got right:
0.5 - Possible
48 - Possible
-6 - Not possible
0 - Not possible
BUT....
3 is possible
Step-by-step explanation:
When we want to know the side lengths of a rectangle and we have possible choices, we want to look at if it's in the realm of possibility. That is, if it's physically possible. You have 5/6 correct, so I think you've done a good job so far. But what you got wrong was the statement that 3 is not possible.
3 is possible, because 24 is divisible by 3. The length would then be 8. So, what you should have put is that 3 is Possible.

f(x) = (x + 2)2 – 16
lesser r =
greater x =
Answer:
lesser x: - 6
greater x: 2
Step-by-step explanation:
f(x) = (x + 2)² – 16
(x + 2)² – 16 = 0
(x + 2 + 4) (x + 2 - 4) = 0
(x + 6)(x - 2) = 0
roots (zero): x = -6 or x = 2
The frequency table shows the results of drawing 20 cards from a bag of 100. There are an
equal number of cards of each color in the bag. Which color has the same frequency as the
distribution of colors in the bag?
White color has the same frequency as the distribution of colors in the bag.
The statistic is the study of mathematics that deals with relations between comprehensive data.
Here,
in the bag, there are 100 cards, and an equal number of cards in colors blue, red, white, and yellow.
Frequency of each color card in bag = 100 / 4 = 25
Now,
if 20 colors have been drawn, the equally distributed frequency of each color,
= 20 / 4 = 5 card,
So from the table, the white color has a frequency of 5.
Thus, the white color has the same frequency as the distribution of colors in the bag.

John is two years younger than his sister, Annie. Last year, John was half Annie's age. How old are John and Annie now?
Answer: John is 3 and Annie is 5
Step-by-step explanation:
because to be half of someone's age while being to years younger it would have to be 2 and 4 - but then a year passed and so the are now 3 and 5.
Answer: John is 3 and Annie is 5
Step-by-step explanation:
Half of 4 is 2 so last year John was 2 and Annie 4 and like a year has passed we add 1 to 2 and 4 which helps us determine that John is now 3 and Annie 5
Can two polynomials be subtracted such that the difference is a trinomial? If so, give an example. (1 point) O Yes. (3x + 3) - (3x + 2y + 3) O Yes. (3x + 3) - (2x + y + 3) O No. Two polynomials can never be subtracted such that the difference is a trinomial. O Yes. (3x + 3) - (2x + 2y + 4)
Answer:
(d) Yes. (3x + 3) - (2x + 2y + 4)
Step-by-step explanation:
The first answer choice results in a monomial, -2y
The second answer choice results in a binomial, x -y
The third answer choice is proved wrong by the fourth answer choice.
The fourth answer choice results in x -2y -1, a trinomial.
