Answer:
Option A.) $162
Alex pays $162 in finance charges.
What is Installment Plan ?An installment plan is a way of buying goods gradually. You make regular payments to the seller until, after some time, you have paid the full price and the goods belong to you.
According to the question
The cost Price of the motor bike is $3,500.
10% down payment = $350
The amount that needs to be financed = $3500-350=$3150
Time Period = 12 months
Each installment = $276
Total amount paid = $276* 12 = $3312
Therefore Alex pays $3312-3150 = $162 in finance charges.

Complete Question
The total cost of a new calculator is
$81.05. This price includes a 10% student discount. Followed by a 6.5% sales tax. What was the original price of the calculator, not including the tax or the discount?
A. $77.69
B. $83.99
C. $78.80
D. $84.56
Answer:
D. $84.56
Step-by-step explanation:
From the question, we are given the following values
Total cost of a new calculator = $81.05
Student discount = 10%
Sales tax = 6.5%
The formula to use is
Total price = Original price ( 1 ± r)
Where r = rate of the discount or sales tax
Step 1
Find the original price of the calculator without the discount
Because we are calculating using discount we are using the minus sign
Total price = $81.05
r = 10% = 0.1
Total price = Original price ( 1 - r)
$81.05 = Original price (1 - 0.1)
$81.05 = Original Price × 0.9
Original price = $81.05÷ 0.9
= $90.055555556
Approximately, the original price without the 10% discount is $90.06
Step 2
Find the Original price without the sales tax
Because we are calculating using sales tax we are using the plus sign
Total price = $90.06
This is because the Original price without the discount = Current total price with sales tax for step 2
r = 6.5% = 0.065
Total price = Original price ( 1 + r)
$90.06 = Original price (1 + 0.065)
$90.06 = Original Price × 1.065
Original price = $90.06÷ 1.065
= $84.563380282
Approximately, the original price without the 10% discount and 6.5% sales tax is $84.56

A six-sided die is rolled twice. What is the probability that the result of both rolls are
a 1?
01/6
2/36
1/36
2/6
Answer:
1/36
Step-by-step explanation:
If a cube rolls and it landed on one it’s 1/6 if u rolled he same cube and got one too then it’s still 1/6 so now u just multiply them
Hope this helps
Answer:
1/36.
Step-by-step explanation:
Each event of a die being rolled is an independent event, which means that each time you roll the die does not affect the next time you roll it.
The probability of getting a 1 on the first roll is going to be 1/6, since there is only one 1 on the 6-sided die.
The probability of getting a 1 on the second roll is also going to be 1/6, for the same reason.
So, if both rolls are going to be 1s, the probability that will happen is (1/6) times (1/6), which is 1/36.

Solve the compound inequality.
5 < 2x - 1<9
show your work solving the inequality
Answer:
x> 3 and x <5
OR
3 < x <5
Step-by-step explanation:
To solve the compound inequality, we will follow the steps below:
We will first break it into two inequalities.
That is;
5 < 2x - 1<9
5 < 2x - 1 AND 2x - 1<9
Then we will solve separately
5 < 2x - 1
add 1 to both-side of the equation
5 +1 < 2x - 1 +1
6 < 2x
Divide both-side of the inequality by 2
6 /2 < 2x/2
3 < x
x>3
we will now solve the other inequality
2x - 1<9
add 1 to both-side of the equation
2x - 1+1<9 +1
2x < 10
divide both-side of the inequality by 2
2x /2< 10/2
x < 5
Therefore x> 3 and x <5
or
3 < x <5
Answer:
[tex]x = (5 \: . \: 3)[/tex]

Area A : Area B = 24:36
Divide 24:36 by 12
= 2:3
The ratio of the area of Rectangle A to Rectangle B is 2:3.
What is the formula of Area of Rectangle?The area of rectangle for a rectangle of length L and width W is given by
A = L* W
It is measured in square units.
A rectangle is a polygon with four sides, the opposite sides of the polygon is parallel and equal.

Given: ΔABC, AC = BC, AB = 3 CD ⊥ AB , CD = square root of 3 Find: AC
Answer:
AC = 2.30
Step-by-step explanation:
Given: ΔABC, AC = BC, AB = 3 CD ⊥ AB , CD = [tex]\sqrt{3}[/tex].
Since CD ⊥ AB, thus CD divides AB into two equal parts.
From ΔACD, applying the Pythagoras theorem;
[tex]AC^{2}[/tex] = [tex]AD^{2}[/tex] + [tex]CD^{2}[/tex]
= [tex]1.5^{2}[/tex] + [tex](\sqrt{3}) ^{2}[/tex]

= 5.25
AC = [tex]\sqrt{5.25}[/tex]
= 2.2913
∴ AC = 2.30

The function f(x) = −(x + 5)(x + 1) is shown.
On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 3, 4), and goes through (negative 1, 0).
What is the range of the function?
all real numbers less than or equal to 4
all real numbers less than or equal to −3
all real numbers greater than or equal to 4
all real numbers greater than or equal to −3
Answer:
all real numbers less than or equal to 4
which agrees with the first answer option listed
Step-by-step explanation:
The parabola opening down means that its two branches go on towards negative values with no limit. The maximum y-value that this parabola can reach is therefore the y-value of its vertex which is 4, given that the vertex coordinates are (3, 4).
Therefore, the Range of y-values can have any real number that is smaller than or equal to 4
Answer:
all real numbers less than or equal to 4
Step-by-step explanation:
The leading coefficient is negative, so the vertex is a maximum. The y-value of the vertex (4) is the upper limit of the range.
The range is all real numbers less than or equal to 4. (first choice)

Find the area of the right triangle. If necessary, round to the nearest tenth.
A right triangle with side 15 yards and hypotenuse 25 yards.
a.
20 yd
b.
150 yd
c.
60 yd
d.
300 yd
Answer:
B - 150 yd
Step-by-step explanation:
Obviously the first step is to find the missing measurement. To do this, you use the Pythagorean theorem; a² + b² = c².
In this case, let's label the the missing side A, the height B, and the hypotenuse C.
X² + 15² = 25²
Then you must figure out what 15² and 25².
15² = 225
25² = 625
The next step is to subtract 15² (225) from 25² (625), which will give you the result of X².
625 - 225 = 400.
Now you know X² = 400, you can find the square root of 400 to give you the length of the triangle.
√400 = 20.
The missing length of the triangle is 20 yards.
Now it's just a matter of finding the area by using the formula;
A = [tex]\frac{bh}{2}[/tex]
Or,
(20 × 15) ÷ 2 = 150.
And there's your answer. Don't forget to add the units.

His car is speeding up.
His car is slowing down.
His car is traveling at a constant speed.
Answer:

Step-by-step explanation:
The statement which best describes what is happening in section C is His car is slowing down.
What is Speed?Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.
Speed is a scalar quantity as it only has magnitude and no direction.
The graph is attached below.
There are 4 sections on the graph.
In the section A, the car is speeding up since the speed is increasing as the time increases.
In the section B, the speed is constant as the time increases. This means his car is traveling at a constant speed.
In the section C, speed is decreasing with time. So the car is slowing down.
In the section D again the car travels at a constant speed.
Hence in section C, car is slowing down.

The length of a rectangle is 2 inches less than three times it’s width.and it’s perimeter is 36 inches .find the width of the rectangle. A. 5 in B .10 in C.4in
Answer:
A
Step-by-step explanation:
Let width =w in
Length = 3w - 2 in
Perimeter of rectangle = 36 inches
2* (length + width ) = 36
2*(3w -2 + w) = 36
2* (4w -2 ) = 36
2*4w - 2*2 = 36
8w - 4 = 36
Add 4 to both sides
8w - 4 + 4 = 36 +4
8w = 40
Divide both sides by 8
8w/8 = 40/8
w = 5
Width = 5 in
