32 gal/min = what qt/h

Answers

32g/m = 32*60 = 1920 gallons per hour

1 gallon = 4 quarts

1920 *4 = 7680 quarts per hour

Answer: 7529.4 qt/hr

Step-by-step explanation:

The conversion used from gal to qt is:

1 gal = 4 qt

32 gal= [tex]\frac{4}{1}\times 32=128[/tex]

The conversion used from min to hr is:

60 min = 1 hr

1 min =[tex]\frac{1}{60}\times 1=0.017hr[/tex]

We are asked: 32 gal/min = ? qt/hr

[tex]32gal/min=\frac{128}{0.017}qt/hr=7529.4qt/hr[/tex]

Therefore, the conversion 32 gal/min = 7529.4 qt/hr

There are two sizes of trucks available: larger truck with a 2.5-ton payload, and smaller trucks with 1.5-ton payload. To unload a freight train 21 larger trucks are needed . How many smaller trucks would be needed for the same job?

Answers

You can find the answer to this question by multiplying 21 by 2.5 to find the total weight ton which would be 52.5, then you would divide 52.5 by 1.5 to find the number of small trucks needed to equal 52.5 ton which would be 35 smaller trucks. So your answer should be 35 smaller trucks are needed to do the same job.

What is Angle?

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

In the given figure l is parallel to m.

A transversal is passing through parallel lines hence corresponding angles are formed.  

The angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line.

So 2x=64

Divide 2 on Both sides

x=32

Hence the value of x is 32⁰.

Which expression is equivalent to (3a5 + b4)2

Answers

Is it multiple choice or do you have to write a answer?

Answer:

The expression [tex]9a^{10}+6a^2b^4+b^8[/tex] is equivalent to the given expression.

Step-by-step explanation:

The given expression is

[tex](3a^5+b^4)^2[/tex]

Use algebraic formula:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex](3a^5+b^4)^2=(3a^5)^2+2(3a^5)(b^4)+(b^4)^2[/tex]

[tex](3a^5+b^4)^2=3^2(a^5)^2+6a^5b^4+(b^4)^2[/tex]

Use exponent property:

[tex](a^m)^n=a^{mn}[/tex]

[tex](3a^5+b^4)^2=9a^{10}+6a^5b^4+b^8[/tex]

Therefore expression [tex]9a^{10}+6a^5b^4+b^8[/tex] is equivalent to the given expression.

Question 6

y = -(5/2)x

We need points in the form (x,y).

Select different x-values to solve for y. This will create points to plot.

Let x = -2, -1, 0, 1, 2

Note: These are just random numbers I selected.

I will do two only.

Let x = -2

y = -(5/2)(-2)

y = -(5/2)(-2/1)

y = (10/2)

y = 5

Our first point to plot is (-2,5).

Let x = -1

y = -(5/2)(-1)

y = 5/2

Our next point to plot is (-1, 5/2).

Continue by letting x = 0, 1, and 2.

This will give you three more points to plot.

After plotting all points on the xy-plane, connect each point with a straight line.

Note: This line crosses the origin starting in quandrant 2 into quadrant 4..

At one college, GPA's are normally distributed with a mean of 2.7 and a standard deviation of 0.5. What percentage of students at the college have a GPA between 2.2 and 3.2?

Answers

Final answer:

About 68.27% of students at the college have a GPA between 2.2 and 3.2 because these values correspond to z-scores of -1 and +1, respectively, in a normal distribution.

Explanation:

To find the percentage of students at the college who have a GPA between 2.2 and 3.2, we will use the properties of the normal distribution. The mean GPA is 2.7 and the standard deviation is 0.5.

First, we calculate the z-scores for the GPAs of 2.2 and 3.2:

z-score for 2.2 = (2.2 - 2.7) / 0.5 = -1

z-score for 3.2 = (3.2 - 2.7) / 0.5 = +1

The z-score represents the number of standard deviations a data point is from the mean. In a standard normal distribution, the percentage of data between z-scores of -1 and +1 is approximately 68.27%.

Therefore, about 68.27% of the students at the college have a GPA between 2.2 and 3.2.

The Burmese pythons can be anywhere from 16 to 23 feet long. What is the difference in length inches between the longest and shortest Burmese python?

Answers

16*12=192
23*12=276
276-192
=84 inches

Answer: There is a difference of 84 inches.

Step-by-step explanation:

Since we have given that

Longest length of python = 23 feet

Shortest length of python = 16 feet

As we know that

1 feet = 12 inches

23 feet = 23×12=276 inches

16 feet = 16×12=192 inches

Difference between them is

276-192=84 inches

Hence, there is a difference of 84 inches.

if two lines in a plane are cut by a transversal so that a pair of consecutive interior angles is supplemantary are the lines parallel?

Answers

yes, and you can look at the interior angle theorem for extra evidence. hope this helps, xx
Final answer:

When two lines in a plane are cut by a transversal and a pair of consecutive interior angles is supplementary, the lines are parallel.

Explanation:

When two lines in a plane are cut by a transversal and a pair of consecutive interior angles is supplementary, the lines are parallel.

We know that consecutive interior angles are located on the same side of the transversal and are inside the two lines.

Since the consecutive interior angles are supplementary, they add up to 180 degrees. This indicates that the lines are parallel.

The cost for a business to make greeting cards can be divided into one-time costs, and repeated costs, suppose the total to make 300 cards is $900.00, and the total to make 650 is 1,600.00. What is the total cost to make 1,000 cards? Round your answer to the nearest dollar
A) 2,100.00
B) 2,300.00
C)2,500.00
D)3,000.00

Answers

The Answer is A 2,100.00 hope this helps
(300,900),(650,1600)
slope = (1600 - 900) / (650 - 300) = 700/350 = 2

y = mx + b
slope(m) = 2
(300,900)...x = 300 and y = 900
sub and solve for b
900 = 2(300) + b
900 = 600 + b
900 - 600 = b
300 = b

so ur equation is : y = 2x + 300....so ur 1 time cost is $ 300 and ur repeated cost is $ 2 per card (with x being the number of cards)

for 1000 cards...
y = 2(1000) + 300
y = 2000 + 300
y = 2300 <=== cost for 1000 cards

Find the domain and range of x + y = 1. Then determine whether it is a function.

Answers

The domain is all real numbers and the range is all real numbers.
(-∞, ∞) for both.

It is a function.
Final answer:

The domain and the range of the equation x + y = 1 are both all real numbers. The equation is a function since each x-value corresponds to a unique y-value.

Explanation:

The question is asking us to find the domain and range of the equation x + y = 1, and to determine whether it is a function.

The domain of an equation is the set of all possible x values. For this equation, we can substitute any real number for x, therefore, the domain is all real numbers.

The range of an equation is the set of all possible y-values. In this equation, for any given value of x, there will be a corresponding value of y (y = 1 - x). Therefore, the range of the equation is also all real numbers.

Whether an equation defines a function or not depends on whether each x-value corresponds to a unique y-value. For this equation, each x-value does correspond to a unique y-value, so it is indeed a function.
