Answer:

$1.02

Step-by-step explanation:

We are told that Clark buys 2 gallons of paint for $ 16.39.

To find the cost per pint of paint let us convert amount of paint in gallons.

1 gallon = 8 pints.          

2 gallons= 8*2 pints= 16 pints.

Now let us find cost per pint of paint by dividing the total cost of paint by number of pints in 2 gallons.

[tex]\text{The cost per pint of paint}=\frac{16.39}{16}[/tex]

[tex]\text{The cost per pint of paint}=1.024375[/tex]

Upon rounding our answer to nearest cent we will get,

[tex]\text{The cost per pint of paint}=1.02[/tex]

Therefore, the cost per pint of paint is $1.02.

Answer:

8 minutes

Step-by-step explanation:

time = distance/speed

A decrease of 15 mph from 45 mph means the speed on the second segment is 30 mph. Filling in the given values in the above equation, we have ...

... time = (4 mi)/(30 mi/h) = 4/30 h = 8/60 h × (60 min/h) = 8 min

Answer:

A: 4.07 ounces

Step-by-step explanation:

17.0 - 12.93 = 4.07

Answer:

The weight of the mystery substance added by Tim is 4.07 ounces. Hence option A is correct.

Solution:

Given, Tim is measuring the weight (in ounces) of a substance for a science experiment.  

Tim added a mystery substance (m) to his experiment.  

Tim used the equation 12.93 + m = 17.0 to find out how much he added.

We have to find how much of the mystery substance (m) did Tim add to his experiment?  

Now, from the given equation, 12.93 + m = 17.0 → m = 17.0 – 12.93 → m = 4.07

Hence, the weight of the mystery substance is 4.07 ounces, i.e. option A is correct.

Answer:

185.39 m

Step-by-step explanation:

Central angle = 8π/5 radians

Let's convert radians to degrees.

Answer:

The length of arc is 185.39 m      

Step-by-step explanation:

Given that in a circle with a radius of 36.9 m, an arc is intercepted by a central angle of [tex]\frac{8\pi}{5}[/tex] radians.

we have to find the arc length.

[tex]Radius=36.9 m[/tex]

[tex]\text{Central angle=}\frac{8\pi}{5}[/tex]

The arc length can be calculated by the formula

[tex]L=r\theta[/tex]

[tex]\text{where r is radius and }\theta \text{ is central angle in radians. }[/tex]

[tex]L=36.9 \times \frac{8\pi}{5}[/tex]

[tex]L=36.9 \times \frac{8\times 3.14}{5}[/tex]

[tex]L=\frac{926.928}{5}=185.3856\sim 185.39 m[/tex]

hence, the length of arc is 185.39 m

Answer:

2 hours

Step-by-step explanation:

using the relationship

distance = speed × time, then

time = [tex]\frac{distance}{speed}[/tex] = [tex]\frac{30}{15}[/tex] = 2 hours

It will take 2 hours to cover 30 miles so option (C) is correct.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

A cyclist rode at an average speed of 15 mph for 30 miles.

So,

15 miles ⇒ hour

Multiply by 2

2 hours ⇒ 30 miles.

Hence "It will take 2 hours to cover 30 miles".

Using the Triangle Inequality Theorem, the third side of the triangle must be less than the sum of other two sides and more than the absolute difference of the two sides. With the sides 7 and 11 given, the third side must be more than 4 but less than 18. Therefore, 19 cannot be the length of the third side.

In mathematics, particularly in geometry, the length of the third side of a triangle when the lengths of two sides are known, can be determined by using the Triangle Inequality Theorem. This theorem states that the length of any side of a triangle must be less than the sum of the lengths of the other two sides. In this case, the lengths of the two sides are given as 7 and 11. The sum of these two lengths is 18.

So the possible length of the third side must be less than 18 but more than the absolute difference of 7 and 11 (which is 4). Hence, the third side can be more than 4 and less than 18. Therefore out of the options provided, the value 19 could not be the length of the third side of the triangle.

Answer:

y intercept

Step-by-step explanation:

At first I didn't think there was enough information, but there is. In general terms, for any polynomial which is also a function, making x = 0 gives the point where (0,b) = the y intercept.

For example

using f(x) = x^2 + 4x + 6 when x = 0 the result left is f(0) = 6 so the y intercept is (0,6)

If you have x^2 + 6x the y intercept is (0,0)

Part A:

The range is the difference between the highest and lowest values:

Highest value = 78

Lowest value = 40

Range = 78-40 = 38

Part B:

The interquartile range is the difference between Q1 and Q3.

Q1 is the middle value of the lower half and Q3 is the middle value of the upper half.

There are 11 total numbers,  40 , 64, 66, 67,67,68,69,70, 71, 72, 78

The median would be the middle value, 68, so the lower half would be the 5 numbers below 68:  40 , 64, 66, 67,67.

The middle value of those numbers would be 66

The upper half are the 5 numbers above 68: 69,70, 71, 72, 78.

The middle value of those numbers is 71

The interquartile range would be 71 - 66 = 5

Part C:

The interquartile range is the better measure.

Answer:

(f+g)(x) = 13x + 3

Step-by-step explanation:

Rewrite  f(x)=2x+7 and g(x)=11x-4 in columns, as follows:

f(x)=2x+7

+g(x)=11x-4

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

Now add each column separately.

f(x)+g(x) = (f+g)(x) ("the sum of functions f and g")

2x + 11x = 13x, and, finally, 7-4 = 3.

Therefore,

 f(x)=2x+7

+g(x)=11x-4

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

(f+g)(x) = 13x + 3

Answer:

Step-by-step explanation:

The real rate of return is calculated as the difference between rate of interest and the inflation.

so,Interest=2.5%

Inflation=1%

=2.5-1

=1.5%

Answer:

1.485 % ( approx )

Step-by-step explanation:

We know that,

[tex]\text{Real rate of return}=\frac{1+\text{Nominal rate}}{1+\text{Inflation rate}}-1[/tex]

Given,

Nominal rate = 2.5 % = 0.025

Inflation rate = 1 % = 0.01,

[tex]\implies \text{Real rate of return}=\frac{1+0.025}{1+0.01}-1[/tex]

[tex]=\frac{1.025}{1.01}-1[/tex]

[tex]=1.01485149-1=0.01485149\approx 0.01485[/tex]

Thus, the real rate of return is 0.01485 or 1.485 %.

Answer:

21 child tickets

Step-by-step explanation:

For this problem, you'd use a system of equations.

First, define your variables.

x = # of child tickets sold

y = # of adult tickets sold

There were 4 times as many adult tickets (y) as child tickets (x) sold, so:

4 x = y

4 x - y = 0

93 (4 x - y = 0)

372 x - 93 y = 0

The total revenue was $909.30, adult tickets were $9.30 each, child tickets were $6.10 each, so:

6.10 x + 9.30 y = 909.30

10 (6.10 x + 9.30 y = 909.30)

61 x + 93 y = 9093

372 x - 93 y = 0

433 x = 9093

433 x / 433 = 9093 / 433

x = 21

She drove 2 hours at 35 miles per hour for a total of 35 * 2 = 70 miles.

She drove 3 hours at 48 miles per hour for a total of 48 * 3 = 144 miles.

Her total miles were: 70 + 144 = 214.

Her total driving time was 3 + 2 = 5 hours.

Divide her total miles by total time for her average speed:

214 / 5 = 42.8 miles per hour average speed.

Not sure if you need to round the answer or not.

Mrs. Padre's average speed for the entire trip is 42.8 miles per hour, which is calculated by dividing the total distance (214 miles) by the total time (5 hours).

To determine Mrs. Padre's average speed for the whole trip, we need to use the formula for average speed:

Average speed = Total distance / Total time

First, we calculate the distance traveled during each part of the trip:

Next, we sum up the total distance and total time:

Now we can calculate the average speed:

Average speed = 214 miles / 5 hours = 42.8 miles per hour

x = 3

"Standard form" is the form ...

... ax + by = c

where a, b, c are mutually prime integers. The coefficients a and b cannot both be zero. The leading coefficient must be positive. If "a" is zero, then the leading coefficient is "b".

So ...

... x = 3

is in standard form already. (a=1, b=0, c=3)

Further comments on Standard Form

Of course, if the line has irrational slope or intercept, the coefficients cannot all be integers.

The order of the variables may be swapped, in which case the coefficient of y is the leading coefficient and must be positive.

This is the only way a vertical line can be written, as slope-intercept form is undefined for a vertical line.
