You have decided to purchase a car for $22,346.16. The credit union requires a 10% down payment and will finance the
balance with a 5.4% annual interest loan for 36 months. The sales tax in your city is 7.6%, and the license and title
charges are $125.13. Determine the amount that the credit union will finance you for. Round your answer to the nearest
cent.
a $24,179.10
c. $21,761.20
b. $24,169.60
d. $21,752.64
Answer:
(b) [tex]\$24,169.60[/tex]
Step-by-step explanation:
Given: Cost of car is [tex]\$22,346.16[/tex]
Sales tax is [tex]7.6\%[/tex]
The license and title charges are [tex]\$125.13[/tex]
To find: The amount that the credit union will finance.
Solution:
We have,
Cost of car[tex]=\$22,346.16[/tex]
Sales tax is [tex]7.6\%[/tex] of [tex]\$22,346.16[/tex]
Therefore,
sales tax [tex]=\frac{7.6}{100}\times22,346.16=\$1698.31[/tex]
The license and title charges [tex]=\$125.13[/tex]
Now, the amount that the credit union will finance is
cost of car[tex]+[/tex]sales tax[tex]+[/tex]the license and title charges
[tex]=\$22346.16+\$1698.31+\$125.13[/tex]
[tex]=\$24,169.60[/tex]
Hence, the amount that the credit union will finance is [tex]\$24,169.60[/tex].
So, (b) [tex]\$24,169.60[/tex] is correct.
Answer:
b.

find the equation of the line shown;
Answer: Assuming it means slope-intercept, the answer would be y=-2x+9
y = -2x + 9 is the equation of the line given in the graph.
What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given a graph of the line, Where we can see that the line passes through the coordinates (0, 9) and (1, 7)
From the slope-intercept formula of a line:
y = mx +c
Where m is the slope
And c is the value of y at x =0
Thus in our case,
c = 9
and slope m = (y - y )/(x - x)
m = (7-9)/(1-0)
m = -2
so, the equation of the line:
y = -2x + 9
Therefore, the equation of the line in the given Graph is y = -2x + 9.

In triangle ABC, the exterior angle at A measures (3x + 10)°, the exterior angle B measures (5x)°, and the exterior angle C measures (2x + 4)°. Determine the measure of the interior angle at A. THANK YOU AND GOD BLESS....!!!!
9514 1404 393
Answer:
∠A = 66.2°
Step-by-step explanation:
The sum of exterior angles of any polygon is 360°, so you have ...
(3x +10)° +(5x)° +(2x +4)° = 360°
10x +14 = 360 . . . . . . . . . . . . . . .collect terms, divide by °
x + 1.4 = 36 . . . . . . . . . divide by 10
x = 34.6
The interior angle at A is the supplement of the exterior angle there:
∠A = 180° -(3x +10)° = 180° -(3(34.6) +10)°
∠A = 66.2°

x - y = 11 and 3x + 10y = -6 How would I solve by substitution?
Answer:
y = - 3, x = 8
Step-by-step explanation:
x - y = 11, x = 11 + y
Lets solve this equation with substitution: 3x + 10y = - 6
3(11+y)+10y=-6
33+3y+10y=-6
13y=-39
y = - 3
x - (-3) = 11
x + 3 = 11
x = 8
Answer:
use the first equation and solve for the variables
Step-by-step explanation:
for example, to solve for x add y on both sides x=11+y and substitute that to the equation
3(11+y)+10y=-6
that should give you -3
then go back to the equation x=11+y
x=11+(-3)
x=8

In a rectangle FGHI, diagonals FH and GI intersect at E
What is the length of FH?
Answer:
The length of [tex]\overline {FH}[/tex] is;
D. 38 units
Step-by-step explanation:
The given parameters are;
The type of the given quadrilateral FGHI = Rectangle
The diagonals of the quadrilateral = [tex]\overline {FH}[/tex] and [tex]\overline {GI}[/tex]
The length of IE = 3·x + 4
The length of EG = 5·x - 6
We have from segment addition postulate, [tex]\overline {GI}[/tex] = IE + EG
The properties of a rectangle includes;
1) Each diagonal bisects the other diagonal into two
Therefore, [tex]\overline {FH}[/tex] bisects [tex]\overline {GI}[/tex], into two equal parts, from which we have;
IE = EG
[tex]\overline {GI}[/tex] = IE + EG
3·x + 4 = 5·x - 6
4 + 6 = 5·x - 3·x = 2·x
10 = 2·x
∴ x = 10/2 = 5
From which we have;
IE = 3·x + 4 = 3 × 5 + 4 = 19 units
EG = 5·x - 6 = 5 × 5 - 6 = 19 units
[tex]\overline {GI}[/tex] = IE + EG = 19 + 19 = 38 units
[tex]\overline {GI}[/tex] = 38 units
2) The lengths of the two diagonals are equal. Therefore, the length of segment [tex]\overline {FH}[/tex] is equal to the length of segment [tex]\overline {GI}[/tex]
Mathematically, we have;
[tex]\overline {FH}[/tex] = [tex]\overline {GI}[/tex] = 38 units
∴ [tex]\overline {FH}[/tex] = 38 units.
Joshua is training for a race. The ratio of the number of minutes he runs to the number of miles he runs is 24 to 3. He plans to run 10 miles. How many minutes will it take him?
Answer:
Time taken to cover 10 miles = 80 minutes
Step-by-step explanation:
Given:
Ratio [Number of minutes : Number of miles runs] = 24:3
Find:
Time taken to cover 10 miles
Computation:
Number of minutes/Number of miles runs = Time taken to cover 10 miles / 10
24/3 = Time taken to cover 10 miles / 10
Time taken to cover 10 miles = 80 minutes
If the diagonal of a television screen is 24 inches and the width is 16 inches,
what is the height of the screen? Leave the answer in simplified radical form
Please show you're work
Step-by-step explanation:
Let x be the height of the screen.
Using Pythagoras' Theorem,
we have x² + 16² = 24².
Therefore x² = 24² - 16² = 320,
x = √320 = 8√5 in.
The height of the screen is 8√5 inches.

Three years ago Alicia was twice as old as her brother Carlos. In two more years Alicia will be just 50% older than Carlos. How old is Alicia today?
Answer:
13 yearsStep-by-step explanation:
Let the present age of Alicia be x
Let the present age of her brother be y
Three years ago;
Alicia age = x - 3
Her brother's age = y - 3
If three years ago Alicia was twice as old as her brother Carlos, then;
X - 3 = 2(Y-3)
x-3 = 2y - 6
x = 2y - 3 ...1
In two years time;
Alicias age = x+2
Her brother's age = y +2
If in two more years Alicia will be just 50% older than Carlos, then;
x+2 = y + 2 + (0.5(y+2))
x+2 = y+2 + 0.5y + 1
x+2 = 1.5y+3
x = 1.5y + 1 ...2
Equating 1 and 2;
2y - 3 = 1.5y + 1
2y - 1.5y = 1+3
0.5y = 4
y = 4/0.5
y = 8
Since x = 2y-3
x = 2(8) - 3
x = 16-3
x = 13
Hence Alicia will be 13 years old today

You are swinging a bucket in a circle at a velocity of 7.8 ft/s. The radius of the circle you are making is 1.25 ft. The acceleration is equal to one over the radius multiplied by the velocity squared.
a. What is the acceleration of the bucket?
b. What is the velocity if the acceleration is 25 ft/sec2?
Given that,
velocity, v = 7.8 ft/s
Radius, r = 1.25 ft
To find,
a. What is the acceleration of the bucket?
b. What is the velocity if the acceleration is 25 ft/sec²?
Solution,
(a) The centripetal acceleration is given by :
[tex]a=\dfrac{v^2}{r}[/tex]
Put v = 7.8 ft/s and r = 1.25 ft
[tex]a=\dfrac{(7.8)^2}{1.25}\\\\=48.672\ ft/s^2[/tex]
(b) Put a = 25 ft/s² to find velocity.
[tex]v=\sqrt{ar} \\\\v=\sqrt{25\times 1.25} \\\\v=5.59\ ft/s[/tex]
Hence, this is the required solution.

Answer:
k = 16/33
Step-by-step explanation:
Determine k so that 2/3,k and 5/8k are the three consecutive terms of an a.p
k - 2/3 = 5/8k - k
3k-2/3 = 5k-8k/8
Cross product
(3k-2)(8) = (3)(5k-8k)
24k - 16 = 15k - 24k
24k - 16 = -9k
24k + 9k = 16
33k = 16
k = 16/33

The expression which can be used to find the total price of a basket order is [tex]T=42b - 7.5[/tex]
Let the basket orders be b.Given the following data:
Discount = $7.50Cost of orders = $42To determine which expression can be used to find the total price of a basket order:
Since the basket orders had a discount of $7.50, this discount would be substracted from the cost price of the orders, in order to find the total price. Also, the total cost price would be multiplied by number of basket orders.
