The width of a new barn is 27 meters across. Nine meters is equal to approximately ten yards. How many yards wide is the new barn?

Answers

Answer:

If  9 meters is equal to 10 years, then you just need to find out how many times 9 goes into 27 and then multiply that by 10!

9 * 3 = 27

3 * 10 = 30!

Step-by-step explanation:

Hope it helps! =D

The answer is 30 because its 27 meters wide but the questions wants to answer in yards. So it tells you 9 meters is about 10 yards so we divide the 27 by 9 so we can change the unit measure. 27/9=3 3x10= 30

Elliot is moving a table through a doorway. The table is 2 and StartFraction 5 Over 8 EndFraction ft wide and the doorway is 2 and three-fourths ft wide. Which statement explains if the table will fit through the door?

The table will fit because 2 and StartFraction 5 Over 8 EndFraction < 2 and three-fourths.
The table will fit because 2 and StartFraction 5 Over 8 EndFraction > 2 and three-fourths.
The table will not fit because 2 and StartFraction 5 Over 8 EndFraction < 2 and three-fourths.
The table will not fit because 2 and StartFraction 5 Over 8 EndFraction > 2 and three-fourths.

Answers

Answer:

The table will fit

Step-by-step explanation:

Table: 2 3/8 = 19/8

Door: 2 3/4 = 11/4

(Mixed fraction to Improper fraction)

Door: 2 3/4 = 11/4 = 11/4*2 = 22/8

19/8 (Table) > 22/8 (Door)

(Hopefully thats the answer 'cause the question isn't very readable)

Dani's estimate for the cost of tiling her bathroom floor is $50 plus $3 per square foot. Write a linear equation showing the total cost.

Include in Your Answer:

The linear equation written in y=mx + b format.
1 to 2 sentences explaining how you determine the correct linear equation.

Answers

Answer:

The linear equation showing the total cost of tiling Dani's bathroom floor is: y = 3x + 50

The equation is in the form of "y = mx + b", where y represents the total cost, x represents the number of square feet, m represents the cost per square foot ($3), and b represents the fixed cost ($50). The linear equation is determined by using the information provided in the problem, which is the cost per square foot and the fixed cost.

art A: Sam rented a boat at $225 for 2 days. If he rents the same boat for 5 days, he has to pay a total rent of $480.

Write an equation in the standard form to represent the total rent (y) that Sam has to pay for renting the boat for x days. (4 points)

Part B: Write the equation obtained in Part A using function notation.(2 points)

Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.


I need the most help for part c.

Answers

Answer: PART A:

Recall that the equation of a line in standard form is of the form:

ax + by = c

where a, b, and c are constants.

The equation of a line passing through two points:

and

is given by:

Given that Amir rented a scooter at $43 for 3 hours. If he rents the same scooter for 8 hours, he has to pay a total rent of $113.

This,

and

Thus, the equation of the line is given by:

Therefore, the equation of the line in standard form is

PART B:

To write the equation with a function notation, we first express y in terms of x and then change y notation to f(x) notation.

Recall from part 1:

Therefore, the equation obtained in Part A written using function notation is given by:

PART C:

To graph the equation obtained above, we draw the x- and y- axis with the x-axis labelled 'number of hours' and the y-axis labelled 'total rent'.

Next, we choose appropriate scales for x- and y- axis. Depending on the size of your graph book, you can choose an interval of 1 unit for the x-axis and an interval of 10 units for the y-axis.

From part A, we know that the line of the equation passes though points (3, 43) and (8, 113), mark these points and draw a straight line passing theough these points.

The ratio 15:73 represents the ratio of 6th grade athletes to total athletes.

Answers

Answer:

The ratio 15:73 represents the ratio of 7th-grade football players to total players.

Step-by-step explanation:

If you add all the players together, you get 73. The number of 7th-grade football players is 15.

This is really simple! If you add the students all together you get 73! While 15 is the amount of 7 graders playing football. So 15:73

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is orange.

Which statement about probability is true?

The probability of landing on orange is greater than the probability of landing on purple.
The probability of landing on yellow is less than the probability of landing on blue.
The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.

Answers

The probability of landing on yellow is less than the probability of landing on blue.

Explanation:
The probability of landing on yellow is 2/8, while the probability of landing on blue is 3/8. 2/8 is less than 3/8
None of the other answers can be right, because:
the probability of landing on purple (2/8) is greater than the probability of landing on orange (1/8),
the probability of landing on orange (1/8) is less than the probability of landing on yellow (2/8),
and the probability of landing on purple (2/8) is less than the probability of landing on blue (3/8)

the second one cause there is one less section of blue so the possibility of landing on yellow is less than landing on blue

what is the equation of the line slope intercenpt form that passes through the point (8,9) and is parallel to the graph of y=3/4x-2? please explain.

Answers

Answer:

Slope-intercept form  is   y= 4x - 30

Step-by-step explanation:

Step 1: Substitute the slope from original line into the equation of the line

Here slope , m is 4

y= mx +b

where m is the slope

b is the y intercept

So Substituting slope we get,

y= 4x +b--------------------------------------------(1)

Step 2 :Substitute the given point (8,2) into the x and y values  of equation (1)

y = 4x +b

2 =4(8) + b

Step 3: Solve for y intercept values

2 = 32+ b

2-32 =b

-30 =b

Now the y intercept value b= -30

Step 3:  Substitute this value for 'b' in the slope intercept form equation

Substituting the value  in eq (1) we get,

y= 4x +(-30)

y= 4x - 30

PLEASE HELP I HAVE NO CLUE WHAT TO DO I DROPED THE FILE SO PLEASE HELP

Answers

Answer:

y = 3/4x -1/4

Step-by-step explanation:

First, find the slope using the points (3, 2) and (-1, -1):

Slope = m = y2 -y1 / x2 -x1 = -1 -2 / -1 -3 = -3/-4 = 3/4

Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.

-1 = ¾(-1) + b

-1 = -¾ + b

Add ¾ to both sides

-1 + ¾ = b

(-4 + 3)/4 = b

-¼ = b

Substitute m = ¾ and b = -¼ in y = mx + b.

The equation would be:

✅ Y = 3/4x - 1/4

Y=3/4x - 1/4 that is the answer.

$12

----------------------

Let the cost of each car decal is d.

After applying a discount of $2 the total for 25 decals came to $250.

Set up an equation:

25(d - 2) = 250

Solve it for d:

25(d - 2) = 250d - 2 = 250/25d - 2 = 10d = 10 + 2d = 12
