The width of a rectangle is 3/8 the length x of the rectangle. What is the perimeter of the rectangle?

Answer:

y = 0.25x - 5

Step-by-step explanation:

Given line is 4x + y = 3

or y = -4x + 3

Comparing this with slope-intercept form y = mx + c :

slope of this line is -4

Product of slopes of perpendicular lines = -1

⇒ slope of a line perpendicular to this is [tex]\frac{-1}{-4}[/tex] = [tex]\frac{1}{4}[/tex] = 0.25

This line also passes through the point (-4,-6)

The equation of a line having slope m and passing through a point (h,k) is

y - k = m(x - h)

⇒ equation of line perpendicular to given line is y - (-6) = 0.25×{x - (-4)}

⇒ y + 6 = 0.25×(x + 4)

⇒ y + 6 = 0.25x + 1

⇒ y = 0.25x - 5

This is in the slope-intercept form y = mx + c with slope m = 0.25 and y-intercept (0,-5)

If 2a−b/6 = b/3, then ratio a:b = 3 : 2

Given that 2a−b/6 = b/3

We have to find the ratio of a:b

In mathematics, a ratio indicates how many times one number contains another

A ratio between two or more quantities is a way of measuring their sizes compared to each other

let us first solve the given expression

[tex]\frac{2a -b}{6} = \frac{b}{3}[/tex]

On cross multiplication we get,

6a - 3b = 6b

6a = 6b + 3b

6a = 9b

[tex]a = \frac{9b}{6}\\\\\frac{a}{b} = \frac{3}{2}[/tex]

To convert a fraction to a ratio, first write down the numerator, or top number. Second, write a colon. Thirdly, write down the denominator, or bottom number

Therefore ratio a:b = 3 : 2

Answer:

Graph A is the correct answer.

explanation of the answer:

the line starts between 10 and 15 and continues to increase to the top of the graph.

The equation y = 12 + 2x represents the cost of a pizza given the number of additional toppings. The corresponding graph would be a straight line which starts at $12 on the y-axis (no toppings) and goes up by $2 on the y-axis for each increment of 1 on the x-axis (each additional topping).

The equation given in the problem, y = 12 + 2x, is a linear equation that represents the cost of a pizza with an increasing number of toppings.

In this equation, 'x' represents the number of additional toppings and 'y' represents the total cost of the pizza. The graph representing this equation would be a straight line that starts at $12 on the y-axis (representing the cost of a medium
pizza without any additional toppings).

Then, for each increment of 1 on the x-axis (representing adding one topping), the line goes up by $2 on the y-axis (representing the additional cost).

Answer: 2.5 miles per hour

Step-by-step explanation:

this problem is all about conversions

220 ft per minute

first get it to hours, since there is 60 minute in an hour multiply by a factor of 60

220 ft per minute becomes 13200 ft per hour

then you need to covert from ft to mi, there are 5280 ft in 1 mi so divide by 5280

13200 ft per hour becomes 2.5 miles per hour

Answer:

the three consecutive odd integers are 9, 11, and 13.

Step-by-step explanation:

Let's say that the first odd integer is x. The second consecutive odd integer would have to be x+2. (It would not be x+1  because that would result in an even integer. The sum of any two odd numbers is even.) The third consecutive odd integer would be (x+2) +2 or x+4.

The sum of the first, twice the second, and three times the third can be written as:

x+2(x+2)+3(x+4)

This equals 70. We can now distribute and solve for x:

x+2(x+2)+3(x+4)=70

x+2x+4+3x+12=70(distribute)

6x+16=70(combine like terms)

6x=54(subtract 16 from both sides)

x=9(divide by 9)

Thus, the three consecutive odd integers are 9, 11, and 13

Answer:

The coordinates of the lines when both lines meets at point is ( 0, 0 )

Step-by-step explanation:

Given as :

The two lines are

[tex]\frac{2}{3}[/tex]x + [tex]\frac{1}{6}[/tex]y = [tex]\frac{2}{3}[/tex]

And 4 x + y = 4

The coordinate of the lines are obtained when the two lines intersect

Let the coordinate of intersection points are ( x , y )

Now , The first lines as

[tex]\frac{2}{3}[/tex]x + [tex]\frac{1}{6}[/tex]y = [tex]\frac{2}{3}[/tex]

Or, Taking LCM we get ,

[tex]\frac{4x + y}{6}[/tex] = [tex]\frac{2}{3}[/tex]

Cross multiplication both sides

Or, 3 × ( 4 x + y ) = 2 × 6

Or,  3 × 4 x +  3 × y = 12

Or, 12 x + 3 y = 12          ...........A

Other line is 4 x + y = 4

i.e 3 × ( 4 x + y ) = 3 × 4

or, 12 x + 3 y = 12          .........B

Solving both the line equations

(12 x + 3 y ) - ( 12 x + 3 y ) = 12 - 12

I.e x = 0  and  y = 0

So coordinates are ( x , y )  =  ( 0 , 0 )

Hence The coordinates of the lines when both lines meets at point is ( 0, 0 ) Answer

[tex]=\frac{\sin x+\cos x}{\cos x} \times \frac{1}{\sin x+\cos x}[/tex]

Cancelling the common terms (sinx + cosx)

[tex]=\frac{1}{c o s x}[/tex]

We know secant is inverse of cosine

Answer:

Answer (d):  (5, -2)

Step-by-step explanation:

Let's use the substitution method.  Eliminate "x" in the second equation.  Solving the first equation for x, we get  x = -3y - 1.  Subbing this for x in the second equation, we get:

2(-3y - 1) + 2y = 6, or, after multiplying as indicated,

-6y - 2 + 2y = 6.

Combining like terms,

-4y = 8, so that y = -2.  If y = -2, then x is found from x = -3y - 1 (see above):

x = -3(-2) -1 = 5

Then the solution is (5, -2)  (Answer d)

Answer:

The number of shirts to be purchased for price to be same is 6 .

Step-by-step explanation:

Given as :

The price for cool shirt = $ 8

The shipping charge for cool shirt = $ 13

The price for Tees = $ 7.50

The shipping charge for Tees = $ 16

Now, Let The number of shirts = S

So , According to question

∵ price to be same for both companies

∴ $ 8 × S + $ 13 = $ 7.50 × S + $ 16

Or, $ 8 × S - $ 7.50 × S = $ 16 - $ 13

Or, 0.5 S = 3

∴ S = [tex]\frac{3}{0.5}[/tex]

I.e  S = 6

Hence The number of shirts to be purchased for price to be same is 6 . Answer

Answer:

I believe they made $4,550 each week.

Step-by-step explanation:

If they sold 74 puppies in a week, and there are 7 days in a week, You would divide 74 by 7 to get an estimate of 10. So that means that 10 puppies were sold each day. Then, because the puppies cost $65, you would multiple 65 by 10 to get $650. $650 is the amount of money they make in a day. Than multiple 650 by 7 to get $4,550. $4,550 is the amount of money they would have made.

74÷7 = about 10

65×10 = 650

650×7 = 4550

Answer:

A. positive slope.

Step-by-step explanation:

In the least square linear regression of Y on X, the straight line of best fit is given by,

[tex]Y_{s} = \mu_{Y} + \rho \times \frac {\sigma_{Y}}{\sigma_{X}} \times (X - \mu_{X})[/tex] ------------------(1)

[where [tex]Y_{s}[/tex] is the estimated value of Y]

Clearly,  here,

Slope pf the line = [tex]\rho \times \frac {\sigma_{Y}}{\sigma_{X}}[/tex]---------------------------------(2)

Y- intercept = [tex]\mu_{Y} - \rho \times \mu_{X} \times \frac {\sigma_{Y}}{\sigma_{X}}[/tex]-----------------(3)

and,

X - intercept = [tex]\mu_{X} - \mu_{Y} \times \frac {\sigma_{X}}{\rho \times \sigma_{Y}}[/tex]----------------(4) [putting [tex]Y_{s} = 0[/tex] in (1) and taking the value of X]

So,

since [tex]\sigma_{Y}, \sigma_{X} > 0[/tex]

[since [tex]\sigma_{Y} = 0[/tex] or [tex]\sigma_{X} = 0[/tex] will result in a degenerate distribution, hence these cases are discarded]

so, correlation coefficient = [tex]\rho[/tex] > 0 implies

A. positive slope. [as evident from (1)]

clearly from (3) and (4) all the other options are false.

Final answer:

A least squares line of best fit with a positive correlation coefficient always has a positive slope, reflecting the positive relationship between the independent and dependent variables. The y-intercept can be positive or negative and is not determined by the correlation.

Explanation:

The question is asking about the characteristics of a least squares line of best fit when there is a positive correlation coefficient. A positive correlation coefficient means that as the value of the independent variable (x) increases, the value of the dependent variable (y) also increases. From this, it follows that the slope of the line ( he m term in the equation) is positive - reflecting the concept that the slope represents the relationship between two variables, with a positive slope indicating a positive relationship.

The y-intercept (the b term in the equation) could be positive or negative, as it represents where the line crosses the y-axis when x is 0, and this point doesn't affect the direction of the relationship between the variables, just the starting level of the dependent variable. Therefore, the correct answer to the question is simply A. positive slope, as this is the only feature guaranteed by a positive correlation coefficient.

2/5= 12/30

The road is 12/30 miles long, they pave 1/30 each hour.

60x12= 720 minutes= 12 hours

To repave the road that is 2/5 miles long, it will take the road crew 12 hours.

To find out how long it will take the road crew to repave the road, we need to divide the length of the road by the rate at which they can repave. The road is 2/5 miles long and the crew can repave 1/30 miles per hour. To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. So, (2/5) ÷ (1/30) = (2/5) x (30/1) = 60/5 = 12. Therefore, it will take the crew 12 hours to repave the road.
