Heather purchased a motorcycle for $4800 with 40% down. She will make 24
payments of $135.57 at 12% interest. What is the total paid for the motorcycle
including the downpayment?

Answer:

x = 28.3

Step-by-step explanation:

The given equation is not the conditional equation.

Step-by-step explanation:

A conditional equation is true only certain values of the numbers present in it.

    for example  x + 3 = 9  is true only, if x = 6

                         3x - 5 = 10 is true only, if x = 5

The given equation is an Identity equation in which both sides of the equation is equal.    

                     3(x - 4) + 5x = 4x + 4(x - 3)

                     3x - 12 + 5x = 4x + 4x - 12

                                   8x  = 8x.

Answer:

d = 5t + 20

Step-by-step explanation:

d represents the distance and t represents the time, in hours

Let he equation which model this situation ⇒ d = a t + b

Where a and b are constant.

Let the gas station is the starting point

So, at gas station t = 0 , d = 20

∴ 20 = 0 * a + b ⇒ b = 20

When he reaches home 2 hours later notes that he has traveled 30 miles.

and with substituting with b = 20

∴ 30 = 2 * a + 20

2a = 30 - 20 = 10  ⇒ a = 10/2 = 5

∴ d = 5t + 20

The equations that can be used to model this situation d = 5t + 20

Answer:

0.9

Step-by-step explanation:

i) 1 nickel is equal to 5 cents

ii) 36 nickels will equal to = 36 × 5 = 180 cents

iii) 1 dime is equal to 10 cents

iv) 20 dimes will equal to = 20 × 10 = 200 cents

v) the ratio of 36 nickels to 20 dimes will equal to

  =  36 nickels ÷ 20 dimes

 = 180 cents ÷ 200 cents

 = [tex]\frac{9}{10}[/tex]

 = 0.9

To express the comparison of 36 nickels to 20 dimes as a ratio in lowest terms, calculate the value of nickels and dimes in pennies, then simplify the ratio. By converting to pennies and reducing, the ratio of 36 nickels to 20 dimes is 9:10.

The question asks to write the comparison of 36 nickels to 20 dimes as a ratio reduced to lowest terms. To compare the value of nickels and dimes, we must know their value in pennies, the smallest unit of US currency. Since 1 nickel is worth 5 pennies and 1 dime is worth 10 pennies, we can express 36 nickels and 20 dimes in terms of pennies.

36 nickels = 36 x 5 pennies = 180 pennies

20 dimes = 20 x 10 pennies = 200 pennies

Now, we write the comparison as a ratio:

180 pennies : 200 pennies

Next, we reduce this ratio to lowest terms by dividing both numbers by their greatest common divisor, which is 20 in this case:

180 ÷ 20 : 200 ÷ 20

9 : 10

Therefore, the ratio of 36 nickels to 20 dimes reduced to lowest terms is 9:10.

Answer:

2x+4

Step-by-step explanation:

Distribute:

=(2)(x)+(2)(−6)+(2)(8)

=2x+−12+16

Combine Like Terms:

=2x+−12+16

=(2x)+(−12+16)

=2x+4

Final answer:

The simplified expression of 2(x-6)+2(8) is 2x + 4 after distributing the 2 and combining like terms.

Explanation:

To simplify the expression 2(x-6)+2(8), you need to distribute the 2 into the parentheses and then combine like terms. Distributing the 2 into the first set of parentheses gives us 2x - 12.

For the second set, multiplying 2 by 8 gives us 16. So the expression becomes 2x - 12 + 16. Adding together the numerical terms (-12 + 16) gives us 2x + 4. Therefore, the simplified expression is 2x + 4.

420 gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get mixture that is 80% antifreeze

Solution:

Let "x" be the gallons of 90% antifreeze

The, final mixture would contain (x + 60) gallons

Then by given question, we can say,

"x" be the gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get 80 % of (x + 60) gallons

Thus we frame a equation as:

[tex]x \times 90 \% + 60 \times 10 \% = (x + 60) \times 80 \%[/tex]

Solve the above equation for "x"

[tex]x \times \frac{90}{100} + 60 \times \frac{10}{100} = (x + 60) \times \frac{80}{100}\\\\0.9x + 6 = (x+60) \times 0.8\\\\0.9x + 6 = 0.8x + 48\\\\\text{Combine the like terms }\\\\0.9x - 0.8x = 48 - 6\\\\0.1x = 42\\\\x = \frac{42}{0.1} = 420[/tex]

Thus, 420 gallons of 90% antifreeze is used

BB's parents should choose the option with a 4% annual increase on the accumulated amount because it leverages compound interest, likely resulting in significantly higher growth over time compared to the fixed contribution strategy.

The question involves deciding between two financial strategies for Baby Bertha's (BB) savings account: a fixed annual contribution ($1,000 at birth plus $50 per year) versus a dynamic contribution that includes an initial amount plus an annual percentage increase ($1,000 at birth plus an additional 4% of the accumulated amount each year). To determine which option BB's parents should select, we must understand the impact of compound interest and how it can significantly increase the future value of a savings account over time.

With the fixed contribution strategy, the amount added each year is constant, leading to linear growth. In contrast, the 4% annual increase on the accumulated amount option leverages the power of compound interest, likely resulting in exponential growth of the account's value over time. This strategy takes advantage of the principle that earnings are reinvested to generate their own earnings in subsequent years, a core tenet of compound growth.

Given the long-term nature of the saving plan (assuming BB won't withdraw the funds prematurely), the option with a 4% annual increase on the accumulated amount is more advantageous. This decision leverages compound interest, which is known to significantly increase the value of investments over extended periods. Hence, BB's parents should select Grandpa's option for the potential of greater financial growth.

Slope m = 5/6

The points (-2,1)

So; y1 = 1 and x1 = -2

The equation is y - y1 = m(x - x1)

y - 1 = 5/6(x + 2)

Multiply each term by 6

6y - 6 = 5(x + 2)

6y - 6 = 5x + 10

6y = 5x + 10 + 6

6y = 5x + 16

- 5x + 6y = 16

Multiplying by minus

5x - 6y = -16

Answer:

5x - 6y = -16

Step-by-step explanation:

5/6 = (y - 1)/(x - 2)

cross multiplying,

5x + 10 = 6y - 6

5x - 6y = -16

Answer:

D. 5/12

Step-by-step explanation:

I will have a picture attached to the answer. But I will explain it overall.

So let's start off with what information we have: Bella ate 1/4 of the bar and Owen at 1/3 of the same bar.

So how much overall was gone by the two? Well, in this part we will add the two fractions.

1/3 + 1/4 =?

Yet, here's the thing, these two fractions have different denominators. What we have to do is make them the same denominator. In order to do so we have to find the Least Common Multiple of the denominators.

So with that in mind...

Multiples of 3: 3,6,9,12,15,18,21,...

Multiples of 4: 4,8,12,16,20,24...

Do you see a number that 3 and 4 have? Welp, I do! It's 12! So here is what going to happen! We will set up the problem like this!

1/3 times ? equal x/12

+ 1/4 times ? equal x/12

Now you may be wondering what is the question mark for and what is "x"? Here's the thing, since we know the new fraction we have to figure out what times the original denominators equal the new denominator! So with 1/3, what or how do we make the 3 into 12? Well 3 times 4 equals 12! So that is ?. The ? will be 4/4. Because whatever you do to the bottom you do to the top.

1/3 times 4/4 equals 4/12

Now we do the same thing for the 1/4 fraction. Except the question mark will be 3/3 since 4 times 3 equals 12

1/4 times 3/3 equals 3/12

Okay, now we have 4/12 + 3/12= x/12. Let's add the fractions. 4+3=7 and the 12 of the denominator will stay the same. So 1/3+1/4 or 4/12+3/12 now equals 7/12.

The real question is what is LEFTOVER of the granola bar? So we have what was devoured of the bar, so now we can subtract the part that was gone with the whole bar. So...

1 whole bar equals 12/12

- the devoured part equals 7/12

left over or untouched = 5/12

So the answer to the question is D. 5/12

I hope this helps you, I'm sorry this took me a long time, I again do have a picture attached to the answer. If you need any help or have a question please don't be afraid to ask! Have a good day!

Answer: option D.

The total amount of the granola bar is = 1.

Given that they have eaten 1/4 and 1/3 of the bar.

So they have eaten a total of [tex]\frac{1}{4}+\frac{1}{3}=\frac{7}{12}[/tex] of the bar.

So the remaining amount is = [tex]1-\frac{7}{12}=\frac{12}{12}-\frac{7}{12}=\frac{5}{12}[/tex].

So option D is right.

To find the width of a 16-inch laptop screen that is 8 inches tall, we can use the 16:9 aspect ratio typical for screens and calculate that the width is approximately 14.22 inches.

Finding the Width of the Laptop Screen

To find out how wide a 16-inch laptop screen is, given that it is 8 inches tall, we can use the Pythagorean theorem assuming the screen has a 16:9 aspect ratio which is typical for laptop screens. To use the Pythagorean theorem, we first need to establish the diagonal (16 inches) as the hypotenuse of a right-angled triangle, with the height and width as the other two sides.

As per the given scale factor for this problem (1/160), it does not seem relevant to finding the width using the Pythagorean theorem. Instead, we can use the aspect ratio to find the width. For a 16:9 aspect ratio:

Height = 9x

Width = 16x

Given the height (8 inches) and assuming it to be 9x:

9x = 8 inches

x = 8 / 9

Now to find the width which is 16x:

Width = 16 * (8 / 9)

Width = 14.222... inches (approximately)

The width of the screen is therefore approximately 14.22 inches.

Devin buys his clothes in Illinois, so he would pay the sales tax rate of Illinois, which is 6.25%. Therefore, the correct answer is D. 6.25%.

Certainly! Devin buys his clothes in Illinois, where the sales tax rate is 6.25%. This means that for every dollar he spends on clothes, he pays an additional 6.25 cents as tax.

To calculate how much tax Devin pays on a $100 purchase, you can use the formula:

[tex]\[ \text{Tax Amount} = \text{Purchase Amount} \times \text{Tax Rate} \][/tex]

Substitute the values:

[tex]\[ \text{Tax Amount} = \$100 \times 0.0625 \][/tex]

[tex]\[ \text{Tax Amount} = \$6.25 \][/tex]

So, if Devin buys clothes worth $100 in Illinois, he would pay $6.25 as sales tax, which corresponds to the 6.25% tax rate of Illinois.

Answer:

Part 1) The sum of the two angles equals 70 degrees

Part 2) The complementary angle is 19 degrees and the supplementary angle is 109 degrees

Step-by-step explanation:

Part 1) we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle JKL

[tex]m\angle JKL+m\angle KLJ+m\angle LJK=180^o[/tex]

we have

[tex]m\angle JKL=110^o[/tex]

substitute

[tex]110^o+m\angle KLJ+m\angle LJK=180^o[/tex]

[tex]m\angle KLJ+m\angle LJK=180^o-110^o[/tex]

[tex]m\angle KLJ+m\angle LJK=70^o[/tex]

therefore

The sum of the two angles equals 70 degrees

Part 2) we know that

If two angles are complementary, then their sum is equal to 90 degrees

If two angles are supplementary, then their sum is equal to 180 degrees

step 1

Find the complementary

Let

c ----> the complementary angle

[tex]m\angle c+71^o=90^o[/tex]

[tex]m\angle c=90^o-71^o=19^o[/tex]

step 2

Find the supplementary

Let

s ----> the supplementary angle

step 1

Find the complementary

Let

c ----> the complementary angle

[tex]m\angle s+71^o=180^o[/tex]

[tex]m\angle s=180^o-71^o[/tex]

[tex]m\angle s=109^o[/tex]

therefore

The complementary angle is 19 degrees and the supplementary angle is 109 degrees

c = 2πr = 2π(8) = 16π = 50.3 ft rounded to the nearest tenth

Find the value of b

we know that

[tex]m\angle MQR=m\angle LQX[/tex] ----> by vertical angles

substitute the given values

[tex](-3b+63)^o=(90-12b)^o[/tex]

solve for b

[tex]12b-3b=90-63\\9b=27\\b=3[/tex]

step 2

Find the measure of angle LQR

we know that

[tex]m\angle LQR+m\angle MQR=180^o[/tex] ---> by supplementary angles (form a linear pair)

[tex]m\angle MQR=(-3b+63)^o[/tex]

substitute the value of b

[tex]m\angle MQR=(-3(3)+63)=54^o[/tex]

substitute in the expression above

[tex]m\angle LQR+54^o=180^o[/tex]

[tex]m\angle LQR=180^o-54^o=126^o[/tex]

Solution:

Let the number of students in first period be "x"

Let the number of students in second period be "y"

Let the number of students in third period be "z"

There are 158 students registered for American History classes.

Therefore,

x + y + z = 158 ---------- eqn 1

There are twice as many students registered in second period as first period

number of students in second period = twice of number of students in first period

y = 2x ------- eqn 2

There are 10 less than three times as many students in third period as in first period

number of students in third period = 3 times number of students in first period - 10

z = 3x - 10 ------ eqn 3

Substitute eqn 2 and eqn 3 in eqn 1

x + 2x + 3x - 10 = 158

6x = 168

Substitute x = 28 in eqn 2

y = 2(28)

Substitute x = 28 in eqn 3

z = 3(28) - 10

z = 84 - 10

Thus there are 28 students in first period and 56 students in sceond period and 74 students in third period

The solution is [tex](3,4)[/tex]

Step-by-step explanation:

To solve the equation by substitution method, we need to substitute an equivalent value of a variable in one equation to an another equation.

The given two equations are [tex]y=4x-8[/tex] and [tex]y=2x-2[/tex] .

Thus, we know the equivalent value of y from one equation, let us subsitute the value of y from the equation [tex]y=2x-2[/tex] to the equation [tex]y=4x-8[/tex]

[tex]4x-8=2x-2[/tex]

Subtracting 2x from both sides of the equation, we get,

[tex]2x-8=-2[/tex]

Adding 8 to both sides of the equation, we get,

[tex]2x=6[/tex]

Dividing by 2 on both sides of the equation,

[tex]x=3[/tex]

Now, substituting [tex]x=3[/tex] in the equation [tex]y=2x-2[/tex], we get,

[tex]\begin{aligned}y &=2 x-2 \\&=2(3)-2 \\&=6-2 \\y &=4\end{aligned}[/tex]

Thus, the solution is [tex](3,4)[/tex]

Final answer:

To find the sides of the triangle, set the shortest side as x cm, leading to the calculation that the shortest side is 17 cm, the second side is 37 cm, and the third side is 34 cm.

Explanation:

The question is based on finding the lengths of the sides of a triangle given the perimeter and relationships between the sides. Let the shortest side be x cm. Therefore, according to the information given, the second side is 3 cm longer than twice the shortest side, which makes it 2x + 3 cm, and the third side is twice as long as the shortest side, so it is 2x cm. The perimeter of the triangle, which is the sum of the lengths of its sides, is 88 cm. We can set up the equation to solve for x:

x + (2x + 3) + 2x = 88

5x + 3 = 88

5x = 85

x = 17 cm

Thus, the shortest side of the triangle is 17 cm, the second side is 2(17) + 3 = 37 cm, and the third side is 2(17) = 34 cm.
