Answer:

0.9 / 90%

Step-by-step explanation:

54/60

=0.9

To calculate Kevin's score as a percent, we divide the number of correct answers by the total number of questions and multiply by 100. The answer, rounded to the nearest tenth of a percent, is 90.0%.

The subject of this question is Mathematics, particularly the area concerning percentage conversions. Kevin got 54 questions correct out of a total of 60 questions. To find Kevin's score as a percent, we first need to divide the number of questions he answered correctly (54) by the total number of questions (60). This gives us a decimal (0.9). To convert this decimal to a percent, we multiply by 100, which gives us 90%. This is Kevin's raw score. But the question wants the score rounded to the nearest tenth of a percent, so the final answer is 90.0%.

Answer: i would help but i'm confused....what problem? can yhu attach it so i could help??! - Lexi@helps

Step-by-step explanation:

For this case we must solve the following equation:

[tex]12y + 6 = 6 (y + 1)[/tex]

We apply distributive property on the right side of the equation:

[tex]12y + 6 = 6y + 6[/tex]

We subtract 6y on both sides of the equation:

[tex]12y-6y + 6 = 6\\6y + 6 = 6[/tex]

We subtract 6 from both sides of the equation:

[tex]6y = 6-6\\6y = 0[/tex]

Dividing by 6 on both sides of the equation:

[tex]y = 0[/tex]

So, the result is [tex]y = 0[/tex]

Answer:

[tex]x=\frac{5t^2-a}{6-5t}[/tex]

Step-by-step explanation:

Given equation is

[tex]6x+a=5t(x+t)[/tex]

We have to make [tex]x[/tex] the subject of formula. That means we have to isolate [tex]x[/tex].

[tex]6x+a=5t(x+t)[/tex]

Distribute [tex]5t[/tex]

[tex]6x+a=5tx+5t^2[/tex]

Subtract [tex]a[/tex] both side we get,

[tex]6x+a-a=5xt+5t^2-a[/tex]

[tex]6x=5xt+5t^2-a[/tex]

Subtract [tex]5xt[/tex] both side we get,

[tex]6x-5xt=5xt-5xt+5t^2-a\\6x-5xt=5t^2-a[/tex]

Now, take [tex]x[/tex] common from left side of equation

[tex]x(6-5t)=5t^2-a[/tex]

Divide [tex]6-5t[/tex] both side,

[tex]\frac{x(6-5t)}{6-5t}=\frac{5t^2-a}{6-5t}\\\\x=\frac{5t^2-a}{6-5t}[/tex]

Answer: 2x + 5y = -5

Step-by-step explanation:

Two lines are said to be parallel if they have the same slope.

The equation of the line given :

2x + 5y = 10

To find the slope , we will write it in the form y = mx + c , where m is the slope and c is the y - intercept.

2x + 5y = 10

5y = -2x + 10

y = -2/5x + 10/5

y = -2/5x + 2

This means that the slope is -2/5 ,the line that is parallel to this line will also have a slope of -2/5.

using the formula:

[tex]y-y_{1}[/tex] = m ([tex]x-x_{1}[/tex] ) to find the equation of the line , we have

y - 1 = -2/5(x -{-5})

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

5y - 5 = -2 ( x + 5 )

5y - 5 = -2x - 10

5y + 2x = -10 + 5

therefore :

2x + 5y = -5 is the equation of the line that is parallel to 2x + 5y = 10

Answer: 2x + 5y = -5

Answer:

Step-by-step explanation:

12x-20=6(x-20)-9x

Opening bracket

12x - 20 = 6x - 120 - 9x

Collecting like terms

12x - 6x + 9x = -120 + 20

15x = -100

Dividing by 15

15x/15 = -100/15

x = -20/3

x = - 6 2/3

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

12x - 20 = 6( x - 20) - 9x

pay attention to the brackets as you simplify.

Let's work on it:

12x - 20 = 6x - 120 -9x

Collecting like terms to further simplify the equation.

12x - 6x + 9x = -120 + 20

15x = -100

Let's make x the subject formula by dividing through by 15

Therefore:

x = -100 / 15

Divide through by 5

x = -20 / 3

Since nothing can easily divide through, we turn it to a mixed fraction

x = - 6 2/3

( Minus six whole number, two divided by three)

Answer:

y = 5x - 3.

Step-by-step explanation:

The value of y will go down by 3 units so it is

y = 5x - 3.

The equation y = 9 + 3x represents a line with a y-intercept of 9 and a slope of 3. To translate the line down 3 units, subtract 3 from every y-coordinate.

The equation y = 9 + 3x represents a line with a y-intercept of 9 and a slope of 3. The y-intercept is the point where the line intersects the y-axis, and in this case, it is the point (0, 9). The slope of 3 means that for every increase of 1 on the horizontal axis, the line rises up 3 units on the vertical axis.

To translate the line down 3 units, we can subtract 3 from every y-coordinate. This means that the equation becomes y = 9 + 3x - 3, which simplifies to y = 6 + 3x.

80 USD × (1.0343 AUD / 1 USD)

Solution:

To convert 80 US dollars into Australian dollars.

1 US dollar = 1.0343 AU dollar

1 AU dollar = 0.9668 US dollar

To find 80 US dollars into Australian dollars multiply 80 US dollars by 1.0343

80 AU dollars = 80 × 1.0343/ 1 USD

The expression is 80 USD × (1.0343 AUD / 1 USD)

Hence, the expression which is used to convert 80 US dollars to Australian dollars is 80 USD × (1.0343 AUD / 1 USD).

The undefined terms needed to define parallel lines are "line" and "coplanar," as parallel lines lie in the same plane and never intersect.

To define parallel lines, the undefined terms needed are "line" and "coplanar."

Parallel lines are two lines that lie in the same plane and never intersect, which means they are coplanar and can be extended indefinitely.

So, the correct choice is: Coplanar, line.

Answer:

Step-by-step explanation:

This line goes through the y-axis at 6; therefore, the coordinate at this point is (0, 6).

This line goes through the x-axis at 2; therefore, the coordinate at this point is (2, 0).

The rate of change of a linear function (aka a line) is the slope of the line.  We can use the slope formula to solve for the slope:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Filling in with our coordinates:

[tex]m=\frac{0-6}{2-0}=-\frac{6}{2}=-3[/tex]

The rate of change is -3.  This means that y decreases 3 with every increase in x of 1.

Answer:

Therefore the first option gives the correct answer of a system of equations which has exactly one solution.

Step-by-step explanation:

i) the second option is 2x + 2y = 1  and -2x -2y = 1 . these two equation can be written as 2x + 2y = 1 and 2x + 2y = -1. Therefore we can see that that the expressions for used for the variables x and y are the same but the result is different. This is not possible and so there will be no solutions for these two equations

ii) the third option is 3x + y = -1 and 6x + 2y = -2. therefore these two equations can be written as  3x + y = -1 and 3x + y = -1 (dividing the second equation by 2) and thus we see that both the equations are exactly the same and hence these two equations will have an infinite number of solutions.

iii) the last option is 3x - 2y = 4 and -3x + 2y = 4. these two equations can be written as 3x -  2y = 4 and 3x - 2y = -4. Again we can see in this case that the two equations are exactly the same and therefore these two equations will have an infinite number of solutions.

iv) the remaining option is the first one 2x + y = 3 and 5x - y = 11.  If we add the first equation to the second one we 7x = 14 and therefore x = 2. If we substitute x = 2 in the first equation we get (2 × 2) + y = 3, therefore y = -1.

Therefore the first option gives the correct answer of a system of equations which has exactly one solution.

Answer:x=40

Step-by-step explanation:

The measure of x in each figure, you need to solve the equation 4x + 20 = 180° by isolating the term with x and then solving for x. The solution is x = 40°, so the measure of x is 40 degrees.

The value of x. The given equation is 4x + 20 = 180°, representing a linear pair of angles.

Subtract 20 from both sides of the equation to isolate the term with x:

4x + 20 - 20 = 180 - 20

4x = 160°

Divide both sides of the equation by 4 to solve for x:

(4x)/4 = 160/4

x = 40°
Therefore, the solution to the equation is x = 40°.

Option D

The total earnings of Yvette is $ 47, 400

Solution:

Given that, Yvette earns a $45,000 salary plus a 12% commission on any sales over $10,000

Last year Yvette made $30,000 in sales

Subtract 10,000 from her sales to get the amount she earns commission on:

30,000 - 10,000 = 20,000

Since Yvette gets 12% commission

So amount earned as commission would be 12% of $20,000

[tex]\text{Commission}=20000\times \frac{12}{100}\\\\\text{Commission}=20000\times 0.12\\\\\text{Commission}=2400\left\\\\[/tex]

Yvette also gets a salary of $45,000, so Yvette's total earnings would be $45,000 plus $2,400

[tex]Total\ Earnings = 45000 + 2400 = 47400[/tex]

Thus total earnings of Yvette is $ 47, 400

Answer:

Answer 4/5 or class 2

Step-by-step explanation:

4/5=0.80    Class 3 is 70% 75+5=80, or 80%

Final answer:

After converting the pass rates of the classes to percentages, none of the classes have a pass rate that is exactly 5% greater than another class's pass rate.

Explanation:

The student's question pertains to comparing the pass rates of different math classes to determine which class had a pass rate that was exactly 5% greater than another class's pass rate. To answer this, we need to convert the pass rates for each class to a percentage and then compare them.

For class 1, the pass rate is 16 out of 24, which can be converted to a percentage by dividing 16 by 24 and then multiplying by 100, resulting in approximately 66.67%. Class 3 has a pass rate of 75%, as provided. Class 4 has a pass rate of 0.81, which is already in a decimal format comparable to a percentage; it is simply 81% when expressed as a percentage.

By comparing these percentages, we find that Class 3's pass rate is exactly 5% greater than Class 1's pass rate (75% - 66.67% = 8.33%, which is more than 5%). Therefore, none of the classes have a pass rate that is exactly 5% greater than another class's pass rate.

Answer: the small cup cost the least per ounce

After calculating the cost per ounce for each cup size, we find that the small cup costs the least per ounce at $0.0989, making it the best value.

To determine which size cup offers the best value per ounce, we need to calculate the cost per ounce for each size. This can be done by dividing the cost of each cup by the number of ounces it holds.

For the small cup: $.89 / 9 ounces = $0.0989 per ounce

For the medium cup: $1.29 / 12 ounces = $0.1075 per ounce

For the large cup: $1.59 / 15 ounces = $0.106 per ounce

Now, comparing the cost per ounce for each cup size, we can see that the small cup offers the best value at $0.0989 per ounce.

Step-by-step explanation:

I added tower A and B together (90+180) Which gives me 270. Then I did;

270 * 5= 1350 ft. Hope its correct!

Final answer:

Tower C is 5 times as tall as the combined height of Tower A (90 feet) and Tower B (180 feet), which together are 270 feet tall. Multiplying this by 5 gives us the height of Tower C, which is 1350 feet.

Explanation:

The question asks us to calculate the height of Tower C given the heights of Tower A and Tower B and the relationship between their heights. Tower A is 90 feet tall, and Tower B is 180 feet tall. According to the question, Tower C is 5 times as tall as both Towers A and B combined.

To find the combined height of Towers A and B, we simply add their heights:

Now, we need to calculate the height of Tower C:

Therefore, Tower C is 1350 feet tall.
