Two buses leave a station at the same time and travel in opposite directions. One bus travels 18 km/h faster than the other. If the two buses are 1722 kilometers apart after 7 hours, what is the rate of each bus?​

On dividing 1658 by 25 , the quotient is equal to 66.32.

As given in the question,

Dividend is equal to 1,658

Divisor is equal to 25

Unit place value of 1658 is equal to 8.

25 is not a factor of 1658

Smallest number to 1658 divisible by 25 is 1650

Divide 1658 by 25 we get remainder

Dividend = ( Divisor × quotient) + remainder

1658 = 1650 + 8

        = ( 25 × 66 ) + 8

Remainder is equal to 8

Quotient is equal to 66

In decimal form

1658 ÷ 25

= 66.32 is quotient.

Therefore, the quotient of dividing 1658 by 25 is equal to 66.32.

Answer:

check this one

Step-by-step explanation:

this is the answer

Answer:

The combined value is $704

If you want the average pay as well it is about $235

Step-by-step explanation:

The problem asks for the combined value of the three paychecks. So all you have to do is add them to get 704.

I found the average value by adding them to 704 then dividing it by 3. The 3 came from the amount of values we have which is 3 paychecks. So we divide the total cost by 3 to get 235.

To obtain a score of 85% on a test worth 135 points, one needs to get 115 points. By using proportions, we get the required value.

A proportion is defined as an equality between two ratios.

Consider two ratios a:b and c:d. Then, the proportion we can write,

a: b = c : d

Then, the simplification we have for this proportion is

a/b = c/d or ad = bc

It is given that, a certain test is worth 135 points.

One to get 85% on this test, he/she needs to get X number of points.

So, we can write the proportions as

X : 135 = 85 : 100

⇒ X/135 = 85/100

⇒ X = 85/100 × 135

∴ X = 114.75 ≅ 115 points

The density of  a pumpkin with a mass of 2.0 kg and a volume of 0.0060m³ is  0.003 kg / m³.

Density of the matter means space taken by matter.

To find the density, density = mass of matter / volume of mass.

Given that mass of the pumpkin 2.0 kg and a volume of 0.0060 m³.

Now the density from the formula;

Density = mass of pumpkin / volume of pumpkin

Density = 2.0 / 0.0060

Multiply by 10000,

Density = 20000 / 60

Density = 2000 / 6

Density = 1000 / 3

Density = 0.003 kg / m³

On solving the provided question, we got by the help of Slope formula - [tex]= 5x - y + 5 = 0[/tex]

A line's slope can be calculated as the ratio of how much y rises when x rises by a specific amount. A line's slope, or how much y increases as x increases, is indicated by the word "slope." Along the straight line, the slope is constant (equal) everywhere.

From the figure we got that,

X1 = 0, Y1 = 5

X2 = -1, Y2 = 0

Therefore the solution of this question is ratio length =  every 1 inch of toy car represents 1.5 feet of actual car

In mathematics, a ratio shows how two numbers are multiplied together. In a bowl of fruit, for instance, the proportion of oranges to lemons is eight to six if there are eight oranges and six lemons. Lemons to oranges are divided 6:8 and oranges to all other fruits are divided 8:14 in a similar fashion.

Here,

A toy Jeep measures 12 1/2 inches.

Before calculating the ratio, let's first convert each size into the same unit of measure and decimal points:

=>12 ½ = 25/2  

=> 12.5 inches;

=> 18 ¾ = 75/4

=> 18.75 feet .

The actual length of a jeep is 18.75 feet.

The ratio can now be determined by converting feet to inches.

1 inch of a toy car equals 1.5 feet of an actual car because

=> 1 foot = 12 inches

=>  12.5 inches : 225 inches

 => 225 / 12.5

=> 18 inches

Therefore, every 1 inch of toy car represents 1.5 feet of actual car.

Answer:

x=4/3, 8/3

Step-by-step explanation:

We will solve this in two steps, one where the right hand side is 2, one where it is -2. This is because the equation is satisfied either way when [tex]|6-3x|[/tex] is equal to either of those values.

Let's start with 2. We have [tex]6-3x=2[/tex]. Subtracting 6 from both sides and then dividing by 3 gives us that x = 4/3. This is the first value.

Now, we solve for when it equals -2. We have [tex]6-3x=-2[/tex]. Subtracting 6 from both sides and then dividing by 3 gives us that x = 8/3. This is the second value.

True, In a paired test, a factor is what you are testing to see the effect of because its effect is unknown.

The paired t-test is a technique for determining whether or not the mean difference between two measurement pairs is zero. When your data values are paired measurements, you can apply the test.

The dependent samples t-test, paired difference t-test, matched pairs t-test, and repeated-samples t-test are other names for the paired t-test.

Answer: 12/7

Step-by-step explanation:  The answer is 12/7 because here is what we know: A group of friends collected toys to donate to children in need. After sorting the toys into boxes, that's what we know,  we also know that they found they had 6/7 of a box of stuffed animals, and we also know that they found 5/7 of a box of board games and

1/7 of a box of doll. What they want to know is  In total, how many boxes of toys did the friends collect?  so you take 6/7 from the box stuffed animals they found + 5/7 from the box of board games they found which equals 11/7 then you add the 11/7 with the 1/7 the box of dolls they found.  In total the friends collect 12/7 boxes.

The equation of line in slope-intercept form is,

a.) y = -6x - 47

b.) y = x/6 - 8/3

What is Equation of line ?

A straight line's general equation is y = mx + b, where m denotes the gradient and y = b denotes the point at which the line crosses the y-axis. On the y-axis, this value b is referred to as the intercept.

We know, slope-intercept form is

y = mx + b

The given equation is in point slope form,

a.) y + 5 = -6 (x + 7)

b.)  y + 2 = 1/6 (x-4)

Now, let's write each equation in slope-intercept form,

a.) y + 5 = -6 (x + 7)

y + 5 = -6x - 42

y = -6x - 42 - 5

y = -6x - 47            [which is slope-intercept form]

b.) y + 2 = 1/6 (x-4)

y + 2 = 1/6 * x - 1/6 * 4

y + 2 = x/6 - 2/3

y = x/6 - 2/3 - 2

y = x/6 - [2/3 + 2]

y = x/6 - [(2 + 6) / 3 ]

y = x/6 - 8/3            [which is slope-intercept form]

Hence, the equation of line in slope-intercept form is y = -6x - 47 and y = x/6 - 8/3

Answer: To find the x-intercept of a line, we set y equal to 0 and solve for x. To find the y-intercept of a line, we set x equal to 0 and solve for y.

For the line 5x + 17y = -25, we set y equal to 0 to find the x-intercept:

0 + 17y = -25

17y = -25

y = -25/17

Since we set y equal to 0, the x-intercept is (0, 0).

For the line 6x - 7y = -21, we set x equal to 0 to find the y-intercept:

6x - 7y = -21

-7y = -21

y = 21/7

Since we set x equal to 0, the y-intercept is (0, 21/7).

Therefore, the x-intercept of the line 5x + 17y = -25 is (0, 0) and the y-intercept of the line 6x - 7y = -21 is (0, 21/7).

Simple random sampling is a sort of probability sampling in which a selection of participants is randomly chosen from a population by the researcher.

The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x.

The probability of an event can be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

In order to better grasp probability, let's look at a straightforward application.

Let's say we need to forecast if it will rain or not. Either "Yes" or "No" is the appropriate response to this query.

There is a chance that it will rain or not. Here, probability can be used. Using probability, one may forecast the results of a coin toss, a roll of the dice, or a card draw.

Hence, In probability sampling, a sample is chosen from a population based on the randomization principle, also known as chance or random selection.
