Sonia buys a car for $5,000. Each year, x, the value of the car decreases by $500. Write an equation to find the value of the car, y, after x years. What is the value of the car after 3 years?
Answers
Answer:
$3500, y= 5000-500x
Step-by-step explanation:
You initially have $5000 which you then subtract $500 from each year, where x represents the number of years that passed.
y= 5000-500x
So after 3 years, it should be
y= 5000-500(3)
=5000-1500
=$3500

Five members of the Varsity Math team are running late for a big
competition and hurrying toward the arena - but they forgot that they would
have to cross the stream that cuts through campus. When they reach the
stream, there's a small boat tied up on their side that they can "borrow” to get
to the other side.
The boat will hold one, two or three of the students, but not more.
Fortunately, two of the team members are also on the crew team, and when
the boat contains only one or both of them, they can make it across the stream
in one minute. Unfortunately, the other three teammates are very
inexperienced with boats, and when any of them is aboard, there is so much
awkwardness and flailing that the crossing will take four minutes, regardless
of whether one of the crew teammates is on board.

find the measure of BEK
Answers
Step-by-step explanation:
Angles BEC and KEC are labelled as congruent.
Therefore (6x + 24)° = 10x°, 4x = 24, x = 6.
Hence Angle BEK = (6x + 20)° + 10x°
= (16x + 24)° = 16(6) + 24 = 120°. (C)
The value of ∠BEK will be 120° so option (C) will be correct.
What is congruence?
If two figures are exactly the same in sense of their length side all things then they will be congruent.
If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
In other meaning, if you can copy a figure then that copy and the original figure will be congruent.
Given figure has two triangles ΔCBE and ΔCKE.
The angle of (6x + 24)° is the same as (10x)° ( given congruency of angle by double line)
So,
6x + 24 = 10x
10x - 6x = 24
4x = 24
x = 6°
So,
Angle ∠BEK
∠BEK = (6x + 24) + (10x)
∠BEK = 6(6) + 24 + 10(6)
∠BEK = 120°.
Hence "The value of ∠BEK will be 120° ".

Answer:
(D) 1/2 - 3√3/4πStep-by-step explanation:
Problem 22 is not fully visible with missing detailsProblem 25 is solved onlyDiameter = 20 cm → radius = 10 cm
Each triangle has its side equal to radius = 10 cm
Each shaded region is the difference of area of the sector and triangle
Each sector is 60° as triangles are equilateral
Area of circle is:
πr² = 100πArea of each triangle is:
√3/4a² = √3/4r²= 100×√3/4So the shaded area is:
3(πr²/6 - √3/4a²) = 3(π×10²/6 - √3/4×10²) =100(π/2 - 3√3/4) = 100π(1/2 - 3√3/4π)Since 100π is the area of circle, the shaded area is:
1/2 - 3√3/4π part of area of circle if we divide the shaded area by the area of circle.Correct choice is D

Is a $250 gift for his friend over or under the 12% spending guideline for gifts
Answers
9514 1404 393
Answer:
under
Step-by-step explanation:
On average, there are 4 1/3 weeks in a month, so Andy's salary is equivalent to ...
(4 1/3 wk/mo)($975/wk) = $4225/mo
The spending guidelines are that no more than 12% should be spent on gifts and entertainment, so Andy's gift budget is ...
12% × $4225/mo = $507/mo
A gift of $250 falls well within Andy's monthly gift budget limit of $507.
_____
Additional comment
Andy's housing allowance is about 30% of $4225, or $1267.50. His mortgage expense is over his budget amount by $82.50. Even if Andy takes this from his gift budget, he still has a sufficient amount for the birthday gift.
If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?
Answers
Answer:
The answer for the first part would be 3.89 minutes for the eight graders. There are 60 seconds in one minute so you’d have to take away 29 and add it to the full 4 minutes, which makes the 8th graders best time for the race 4.29 minutes. That’s more than 4 minutes, so the seventh graders would earn the points instead.
Step-by-step explanation:
The seventh graders would earn the points instead and awarded 40 points.

The Anchorage time zone is 18 hours ahead of the Tokyo time zone when it is 5:00 a.m. in Anchorage, it is 11:00 p.m. in Tokyo option (C) is correct.
What is the time zone?For legal, commercial, and social purposes, a time zone is a region that observes a uniform standard time. Instead of strictly following longitude, time zones tend to follow the borders between countries and their subdivisions.
We have:
Time in Anchorage = 5:00 a.m.
Time in Tokyo = 11:00 p.m.
The difference between these two-time zone is:
TIme difference = 18 hours
18 hours ahead of Anchorage is Tokyo.
Thus, the Anchorage time zone is 18 hours ahead of the Tokyo time zone when it is 5:00 a.m. in Anchorage, it is 11:00 p.m. in Tokyo option (C) is correct.

19. Brian bought a new jacket at a discount of 30%. If the original price was $65, how
much did Brian pay for the jacket?
Answers
Answer: Brain paid $ 45.5 for the jacket.
Step-by-step explanation:
Given: Original price of jacket = $ 65
Discount -= 30%
Price after discount = Original price - 30% of Original price
= 65 - 30% of 65
= 65 - (0.3) x 65 [30% = 0.3]
= (65) (1-0.3 ) [Taking 65 common]
= (65)(0.7)
= $ 45.5
Hence, Brain paid $ 45.5 for the jacket.

The sum of 2 numbers is 96. The larger number is 9 less than 4 times the smaller. Find both numbers.
Answers
Answer:
75 & 21
Check:
75 + 21 = 96
21 * 4 - 9 = 75
Correct!
Answer:
the smaller number is 21 and the larger number is 75
Step-by-step explanation:
First make a simple equation where x = the smaller number and y = the larger number
ie: 96=x+y
Now make an equation to find the larger number.
ie: y=4x-9
Now substitute the y value in the first equation for the y value in the second equation
ie: 96=x+(4x-9)
Then solve for x
ie: x=21
Then plug in your new x value into the first or second equation to solve for y.
ie: 96=21+y
ie: y=75
What is the least angle of rotation that maps the regular heptagon onto itself? Round your answer to
the nearest whole degree.
Answers
Answer:
[tex]Minimum = 51^{\circ}[/tex]
Step-by-step explanation:
Given:
[tex]Shape = Heptagon[/tex]
Required
Determine the least angle of rotation that places the heptagon on itself
First, we write out the number of sides of a heptagon
[tex]Sides = 7[/tex]
Next, we write out the measure of 1 complete rotation
[tex]1\ Complete\ Rotation = 360^{\circ}[/tex]
The minimum angle of rotation is then calculated as:
[tex]Minimum = \frac{1\ Complete\ Rotation}{Sides}[/tex]
[tex]Minimum = \frac{360^{\circ}}{7}[/tex]
[tex]Minimum = 51.4285714286^{\circ}[/tex]
[tex]Minimum = 51^{\circ}[/tex]
Hence, the minimum rotation angle is [tex]51^{\circ}[/tex]
The perimeter of a rectangle is about 13.9 cm. If you double the width of the rectangle the perimeter is about 17.8 cm. Find the dimensions of the smaller rectangle.
Answers
Answer:
5cm by 1.95cm
Step-by-step explanation:
Let the length of the rectangle be x
Let the width be y
Perimeter of a rectangle = 2x + 2y
If the initial perimeter of a rectangle is about 13.9 cm, then;
13.9 = 2x + 2y ..... 1
If when the width is double the perimeter is 17.8cm, then;
17.8 = 2x + 4y ..... 2
Subtract 1 from 2;
13.9 - 17.8 = 2y - 4y
- 3.9 = -2y
y = 3.9/2
y = 1.95 cm
Substitute y = 1.95 into 1 to get x;
From 1;
13.9 = 2x + 2y
13.9 = 2x + 2(1.95)
13.9 = 2x + 3.9
2x = 13.9-3.9
2x = 10
x = 5 cm
Hence the dimension of the smaller triangle is 5cm by 1.95cm
