Aiko jumped rope for an amazing 20 minutes. She stopped at 8:05. When did she start jumping?
Answer:
7:45 is when Aiko started jumping rope.
Step-by-step explanation:
If you start with 8:05 then subtract the 5 minutes you only have 15 minutes to calculate. Then you do 60 - 15 because there are 60 minutes in one hour. If you do that you are left with 45 and the hour would be 7 so the answer is 7:45

1/6x=-9 multiply each side of the equation by ___
6x + 9 = 4x - 3
2x + 9 =-3
Multiply both sides by 2
- 4(5x-7)=-18
5x - 7 = 4.5
Multiply both sides by-4
8 - 10x = 7+ 5x
4 - 10x = 3 + 5x
Multiply both sides by 1
x = 4
5x =- 16
Add to both sides
- 4x
12x + 4 = 20x + 24
Add to both sides
3x + 1 = 5x + 6

Find the simple interest earned, to the nearest cent, for the principal, interest rate, and time.
$530, 6%, 1 year
Answer:
The Answer is $3180..Step-by-step explanation:
principal (p) = $ 530Interest Rate (R) = 6%Time (T) = 1 yearSimple Interest (I) = ?By using formula,
Simple Interest (I)= P× T× R/ 100
= $530 × 1 year× 6%
= 530 × 1 × 6
= $3180
Therefore , The simple Interest is $3180.
If you like this answer then mark this answer as BRAINLIEST answer.....Thank you ☺️☺️
The simple interest will be equal to $3180.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
Given that:-
principal (p) = $ 530
Interest Rate (R) = 6%
Time (T) = 1 year
Simple Interest (I) = ?
The formula to calculate the simple interest is given below:-
Simple Interest (I)= P× T× R/ 100
SI = $530 × 1 year× 6%
SI = 530 × 1 × 6
SI = $3180
Therefore, the simple interest will be equal to $3180.

Jason and Eddy are traveling from Jacksonville to Miami, which is a distance of 382 miles. According to the American Automobile Association (AAA) map, it takes 1 hour and 54 minutes to travel from Jacksonville to Daytona, 2 hours and 51 minutes to travel from Daytona Beach to Fort Pierce, 1 hour and 23 minutes to travel from Fort Pierce to West Palm Beach, and 1 hour and 38 minutes to travel from West Palm Beach to Miami. If Jason and Eddy follow the AAA guidelines, what would be their average speed (in mph) for the trip
Answer:
The value is [tex]v = 49.23 \ mph[/tex]
Step-by-step explanation:
From the question we are told that
The distance from Jacksonville to Miami is d = 382 miles
The time it take to travel from Jacksonville to Daytona is [tex]t_1 = 1 \ hour\ and\ 54\ minutes = 1 + \frac{54}{60} = 1.9 \ hours[/tex]
The time it take to travel from Daytona Beach to Fort Pierce is [tex]t_2 = 2\ hours\ and\ 51\ minutes= 2 + \frac{51}{60} = 2.85 \ hours[/tex]
The time it take to travel from Fort Pierce to West Palm Beach is
[tex]t_3 = 1\ hour\ and\ 23\ minutes= 1 + \frac{23}{60} = 1.38 \ hours[/tex]
The time it take to travel from West Palm Beach to Miami [tex]t_4 = 1\ hour\ and\ 38\ minutes= 1 + \frac{38}{60} = 1.63 \ hours[/tex]
Generally the average speed is mathematically represented as
[tex]v = \frac{d}{t_1 + t_2 +t_3 + t_4 }[/tex]
=> [tex]v = \frac{382}{1.9 + 2.85 +1.38 + 1.63 }[/tex]
=> [tex]v = 49.23 \ mph[/tex]
1. If two parallel lines are cut by a transversal, then alternate interior angles are congruent
2. If two parallel lines are cut by a transversal, then corresponding angles are congruent
3. If two parallel lines are cut by a transversal, then alternate exterior angles are congruent
4. If two parallel lines are cut by a transversal, then complementary angles are congruent
the following are my reminders in using this module
By the property of alternate interior angles, Option (1) is the correct statement.
From the figure attached,
∠XWY ≅ ∠ZYWProperty of the alternate angles states, if two parallel lines are cut by a transversal, then the alternate angles are congruent.
By this property,
Lines XW and YZ are the parallel lines intersected by a transversal WY.
Here, ∠XWY and ∠ZYW represent the interior angles between the parallel lines and the transversal.
Therefore, interior alternate angles ∠XWY and ∠ZYW will be congruent.
Hence, Option (1) will be the correct option.

Y-2=7(X -4) what form of an equation is this? please and thank you <3
9514 1404 393
Answer:
linear equation in the point-slope form
Step-by-step explanation:
There are many forms an equation for a line may take. Some of the ones commonly seen are ...
ax +by = c . . . . standard form (a,b,c mutually prime integers; a>0)
y = mx + b . . . . slope-intercept form (m=slope; b=y-intercept)
y -k = m(x -h) . . . . point-slope form (m=slope, (h, k)=point)
__
and some additional ones I commonly use are ...
x/(x-intercept) +y/(y-intercept) = 1
y = m(x -h) +k . . . . variation of point-slope form (m=slope; (h, k)=point)
y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . two-point form (points (x1, y1) and (x2, y2))
bx -ay = bh-ak . . . . line perpendicular to standard form line ax +by = c through point (h, k)
__
If you compare these forms to the equation you're given, you see it matches the "point-slope form" for point (4, 2) and slope 7.
