On weeks days, Aaron gets home from school at 4:30 p.M., and his bedtime is at 9:00 p.M. If he spends 90 minutes playing football, 35 minutes eating dinner, and 1 hour and 45 minutes doing homework, how much time after school will Aaron have left to play video games?
Answer:
40 minutes
Step-by-step explanation:
Time at which Aaron gets home from school = 4:30 PM
Bedtime for Aaron = 9:00 PM
Total available for Aaron = 9:00 - 4:30 = 4 hr 30 minutes
To convert minutes to hours, we need to divide by 60.
Time spent in playing football = 90 minutes = [tex]\frac{90}{60} = 1\ hr\ 30\ minutes[/tex]
Time spent eating dinner = 35 minutes
Time spent in doing homework = 1 hr 45 minutes
Total time spent = 1 hr 30 minutes + 35 minutes + 1 hr 45 minutes = 2 hr 110 minutes = 3 hr 50 minutes
Time left for Aaron to play video games = 4 hr 30 minutes - 3 hr 50 minutes = 40 minutes

Incomplete question:
A fair die is rolled one. What is P(roll less than 4)? If necessary, round your answer to 2 decimal places.
Answer:
P(roll less than 4) = 0.50
Step-by-step explanation:
First, we need to list the sample space.
[tex]S = \{1,2,3,4,5,6\}[/tex]
From the above, we have that:
[tex]n(S) = 6[/tex] i.e. total rolls
Represent Rolls less than 4 with L4; So,
[tex]L4 = \{1,2,3\}[/tex]
[tex]n(L4) = 3[/tex] i.e. number of rolls less than 4
The required probability is calculated as:
[tex]Probability = \frac{n(LA)}{n(S)}[/tex]
[tex]Probability = \frac{3}{6}[/tex]
[tex]Probability = 0.50[/tex]
Answer: 0.50

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mo walked 12 miles in 3 hours.
In 1 hour Mo walked= 12/3
= 4 miles
and, in 5 hours Mo walked
= 5 x 4
= 20 miles.
Hence, Mo walked 20 miles in 5 hours.

The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weight of the crackers in the boxes. What is the weight, in ounces, of one box? 11 ounces per box 12 ounces per box 15 ounces per box 16 ounces per box
Answer:
15 ounces per box
Step-by-step explanation:
What is the weight, in ounces, of one box?
165ounces/ 11 boxes
This means
165ounces per 11 boxes
Hence:
11 boxes = 165ounces
1 boxes = x ounces
Cross Multiply
11x = 165 × 1
x = 165/11
x = 15 ounces
Therefore, the weight, in ounces, of one box is 15 ounces per box.
Answer:
15 ounces per box

NEED HELP NOW One solution to a quadratic equation is x=-5/3 What is true about any remaining solutions? There are no complex solutions. There are no other real solutions. There are two or more complex solutions. There is exactly one complex solution. There is exactly one more real solution. There are at least two more real solutions.
Given:
One solution to a quadratic equation is [tex]x=-\dfrac{5}{3}[/tex].
To find:
The true statement about remaining solutions.
Solution:
We know that, number of solution to a quadratic equation is 2.
According to the complex conjugate root theorem, if a complex number x+iy is a root of an equation then its conjugate x-iy is also a root of that equation.
It means, the complex roots are in the pair of two.
Using complex conjugate root theorem, a quadratic equation has either 0 complex roots or 2 complex roots.
One solution to a quadratic equation is [tex]x=-\dfrac{5}{3}[/tex], which is real.
There are no complex solutions and there is exactly one more real solution.
Therefore, the correct options are A and E.

Answer:[tex](-7-2)=-3(-3-0)[/tex]
Step-by-step explanation:
First use slope intercept form to find the value of b (the y intercept). The slope intercept formula is
[tex]y=mx+b[/tex]
Since we are given the point (-3,2), we can say that y=2 and x=-3. m=-3. Then we get
[tex]2=-3(-3)+b[/tex]
[tex]2=9+b[/tex]
[tex]b=-7[/tex]
Since we now have the y intercept, we can convert it to a point: (0,-7). Plug this into the point slope equation:
[tex](y_{1}-y_{2})=m(x_{1}-x_{2})[/tex]
Our first point is (-3,2). Our second point is (0,-7). Therefore:
[tex]x_{1}=-3\\y_{1}=2\\x_{2}=0\\y_{2}=-7\\m=-3[/tex]
Plugging into the equation, we get
[tex](-7-2)=-3(-3-0)[/tex]

find midpoint and length of line segment that has endpoints (3,5) and (9,-3)
A phone company offers two monthly charge plans. In Plan A, the customer pays a monthly fee of $20 and then an additional 6 cents per minute of use. In Plan B, the customer pays a monthly fee of $31.50 and then an additional 4 cents per minute of use. For what amounts of monthly phone use will Plan A cost less than Plan B? Use m for the number of minutes of phone use, and solve your inequality for m.
Answer:
m>575Step-by-step explanation:
let the total cost be y
and the number of minutes be m
Plan A
$20 and additional 6cent
6cent to dollar =$0.06
the linear expression is given as
y=20+0.06m---------1
Plan B
$31.5 and additional 4cent
6cent to dollar =$0.04
the linear expression is given as
y=31.5+0.04m----------2
Equating 1 and 2 we can find m
20+0.06m=31.5+0.04m
20-31.5=0.04m-0.06m
-11.5=-0.02m
m=11.5/0.02
m=575
therefore m>575

Which step contains an error?
Answer:
Error in step (5)
Step-by-step explanation:

2 Let (2x) = θ
3 Then x = [tex]\frac{\theta }{2}[/tex]
4 cos(θ) = [tex]2\text{cos}^2{\theta}-1[/tex]
5 cos(θ) + 1 = [tex]2\text{cos}^2{\frac{\theta}{2}}[/tex]

Factor x^2+x-12 = 0 and x^2-6x+9 = 0.
Answer: x^2+x-12 = 0 ⇒ x = -4 or x = 3 and x^2-6x+9 = 0 ⇒ x= 3
x^2+x-12 = 0 (Find two numbers that add to 1 and multiply to -12)
x^2-3x+4x-12 = 0 (Factor out like terms)
x(x-3)+4(x-3) = 0 (Group common terms)
(x-3)(x+4) = 0 (Set each term to equal 0 and solve for x)
∴ x = -4 or x = 3
x^2-6x+9 = 0 (It's a perfect square trinomial)
(x-3)^2 = 0
∴ x = 3
Answer: x = -4 and x = 3 for the first one. x- 3 for the second one.

Answer:
112
Step-by-step explanation:
Supplementary angles means that angle A and angle B added together equal 180˚. This mean we can re-write the angle measures into an algebra problem
A(3x+16) + B(2x + 4 ) = 180
Or
5x + 20 = 180
5x + 20 - 20 = 180 - 20
5x = 160
5x/5 = 160/5
x = 32
Now that we know that X = 32, we can plug 32 into the measure of angle A.
A(3x+16)
A(3(32)+16)
A(96+16)
A(112)
Angle A equals 112˚ and Angle B equals 68˚.

2x+ 1 = 19
This is supposed to be two step equations.
Answer:
x=0.1
Step-by-step explanation:
2x+1+=19
19-1=18
2x=18
2/18=0.1
x=0.1
Answer:
x= 9
Step-by-step explanation:
First I would subtract the 1 from 19 which leaves me with 18 then divide both sides by 2 so 2x/2 = 18/2 which gives me 9 now to check. 2 multiplied by 9 =18 plus 1 =1 9. and thats how I get the answ.r
