Answer: d = 12

Step-by-step explanation: First isolate d/3 by subtracting 10 from both sides of the equation. That gives you d/3 = 4.

From here, since d is being divided by 5, multiply both sides of the equation by 5 so d = 12.

(5 - 5)x because it equals -5x+5x which is 0

all the others equal -5x +5

Answer:

(5-5)x

when you distribute the x here it becomes 5x-5x which is 0 this is the only problem that equals 0

To find the calories in a 14 ounce drink, we first determine the calorie content per ounce from a 90 ounce drink. We find it to be about 9.89 calories per ounce. Multiplying this by 14 gives us approximately 138.46 calories in a 14 ounce drink.

To find the calories in a 14 ounce drink, we need to first determine the calorie content per ounce in the 90-ounce drink. This is found by dividing the total calories (890) by the total ounces (90). The number we get from this division (calories per ounce) can then be multiplied by the ounces in the smaller drink (14) to get the number of calories in that drink.

Therefore, a 14 ounce drink from this gas station would have approximately 138.46 calories.

Answer:

Sean earns $7.5 in each hour.

Step-by-step explanation:

Given:

Money earned by Sean = $300

Number of hours worked in a day = 8 hrs

Number of days of work  in a week = 5

We need to find Money earned in each hour.

First we will find Total hours work in a week.

Total hours work in a week is equal to Number of hours worked in a day multiplied by number of days work in a week.

Framing in equation form we get;

Total hours worked in a week = [tex]8\times5 = 40\ hrs[/tex]

Now we will find money earned for each hour.

Money earned each hour will be calculated by Dividing Total Money earned in a week by Total number of hours worked in a week.

Framing in equation form we get;

Money earned each hour = [tex]\frac{300}{40} = \$7.5[/tex]

Hence Sean earns $7.5 in each hour.

Answer:

OPTION C

Step-by-step explanation:

If SOLUTION A has 4 cups then SOLUTION B has 2. If SOLUTION A has 8 then SOLUTION B has 4.

Note that for every 2 cups of Solution A, we have 1 cup of Solution B.

So, OPTION A is incorrect.

If there are 4 cups of Solution A, then there are 4 + 2 cups in total.

That means the ratio of cups of SOLUTION  A to the total number of cups is:

4 : 6 = 2 : 3

Similarly, 8 : 12 = 2 : 3

And, 12 : 18 = 2 : 3

And, 16 : 24 = 2 : 3

So, we see that the ratio is 2 : 3.

Therefore, OPTION C is the correct answer.

Answer:

-8

Step-by-step explanation:

Perpendicular means negative reciprocal of the slope.

Negative reciprocal of 1/8 is -8.

The slope of a line that is perpendicular to y = 1/8x - 9 is -8. This is because perpendicular lines have slopes that are negative reciprocals of each other.

In Mathematics, particularly in algebra, the slope of a line is a measure of the steepness of the line. It's also a central part of the line's equation. In the equation you provided, y = 1/8x - 9, the slope of this line is 1/8.

The property of perpendicular lines is that their slopes are negative reciprocals of each other. The negative reciprocal of 1/8 is found by flipping the fraction to get 8/1 and changing the sign to get -8. Therefore, the slope of a line that is perpendicular to y = 1/8x - 9 is -8.

The shortest possible height of the tower is 24 cm

They used 4 blue blocks and 3 green blocks

Step-by-step explanation:

Tim and his brother are building towers out of blocks

We need to find the shortest possible height of the tower and how many of each color block they used

∵ Tim is using blue blocks that are 6 cm tall

∴ The height of his tower is a number divisible by 6

∵ His brother is using green blocks that are 8 cm tall

∴ The height of his tower is a number divisible by 8

∵ The heights of their towers are equal

∴ The height of the towers must be a number divisible by 6 and 8

Let us write some multiples of 6 and 8 to find the first common multiple of them

∵ The multiples of 6 are 6 , 12 , 18 , 24 , 30 , 36 , .........

∵ The multiples of 8 are 8 , 16 , 24 , 32 , 40 , .............

∵ The first common multiple of them is 24

∴ The shortest possible height of the tower is 24 cm

∵ The height of each blue block is 6 cm

- Divide the height of the tower by the height of the block to

   find the number of blue blocks

∵ 24 ÷ 6 = 4

∴ Time is using 4 blue blocks

∵ The height of each green block is 8 cm

- Divide the height of the tower by the height of the block to

   find the number of green blocks

∵ 24 ÷ 8 = 3

∴ His brother is using 3 green blocks

The shortest possible height of the tower is 24 cm

They used 4 blue blocks and 3 green blocks

Step-by-step explanation:

linear means a straight line graph. This type is quadratic since it has a parabola.

Answer:

Step-by-step explanation:

When we talk about linear and nolinear funciton, we can distinguish them by using their graphs.

A linear function has a linear behaviour, that means it's representes by a straight line.

A nonlinear function doesn't have a straight line behaviour.

That's the easiest way to distinguish wether is a linear function or nonlinear.

Therefore, in this case, you can observe that the graph is not a straight line, that means the function is nonlinear.

Answer:

286

Step-by-step explanation:

If the three-digit number is xyz, then:

x + y + z = 16

y = z + 2

z = 3x

Substitute the third equation into the second:

y = 3x + 2

Substitute this and the third equation into the first:

x + (3x + 2) + (3x) = 16

7x + 2 = 16

7x = 14

x = 2

y = 3x + 2 = 8

z = 3x = 6

The number is 286.

The three-digit number where the sum of its digits equal 16, the tens digit is two more than the unit's digit, and the unit's digit is triple the hundreds digit is 286.

The question involves finding a three-digit number where the sum of the digits is 16, the tens digit is two more than the unit's digit, and the unit's digit is triple the hundreds digit. Let's represent the hundreds digit as 'h,' the tens digit as 't', and the units digit as 'u'. According to the problem, we have three equations:

Substituting the third equation into the first, we get h + (3h + 2) + 3h = 16, which simplifies to 7h + 2 = 16, leading to h = 2. Thus, u = 3h = 6, and t = u + 2 = 8. Therefore, the three-digit number is 286.

Step-by-step explanation:

Answer:

The total number of pages in the e-book is 240.

Step-by-step explanation:

Given:

Logan has completed 75%

Logan has read 180 pages

To Find:

The total number of pages in the e-book= ?

Solution:

Let X be the total number of pages on the e-book

then

=> 75% of X = 180

Now lets find the value of X

X = [tex]\frac{180}{75\%}[/tex]

X = [tex]\frac{180}{\frac{75}{100}}[/tex]

X = [tex]\frac{180}{0.75}[/tex]

X = 240

The total number of pages in the e-book is 240.

To find the total number of pages in the e-book, we can set up a proportion based on the information given. Logan has read 75% of the e-book, which corresponds to 180 pages. We can represent this as:

 75% of total pages = 180 pages

To find the total number of pages, we can express the percentage as a fraction and solve for the total number of pages (let's denote this as P):

[tex]\(\frac{75}{100} \times P = 180\)[/tex]

Now, we can solve for P:

[tex]\(P = \frac{180 \times 100}{75}\)[/tex]

[tex]\(P = \frac{180}{0.75}\)[/tex]

[tex]\(P = 240\)[/tex]

Therefore, the total number of pages in the e-book is 240.
