Answers

3.312 irrational.........

Answer:

3.46227766; irrational

Step-by-step explanation:

The sum of 3/10 and √10 can be written mathematically as:

3/10 + √10

Taking the LCM which is 10

3/10 + √10 = 0.3 + 3.16227766

= 3.46227766

Since we cannot express the resulting value as a ratio of two integers, therefore the value is classified as an irrational number.

A dripping faucet wastes a cup of water if it drips for three minutes. The amount of water wasted varies directly with the amount of time the faucet drips. What is the constant of variation?

A. 1/3
B. 2
C. 1/2
D. 3

Answers

The constant variation I believe would be 1/3 So sorry if I’m wrong

Answer:

A. 1/3

Step-by-step explanation:

Suppose x represents the amount of the water ( in cups ) wasted in t minutes,

∵ The amount of water wasted varies directly with the amount of time the faucet drips,

⇒ x ∝ t

x = kt

Where,

k = constant of variation,

If x = 1, t = 3,

[tex]\implies 1 = k(3)\implies k = \frac{1}{3}[/tex]

Hence, the constant of variation is [tex]\frac{1}{3}[/tex]

Edwin walks for 2 1/2 hours. He walks 1 2/3 miles in the first hour, 1 3/4 miles in the second hour and 1/4 of the total distance in the last 1/2 hour.What is the total distance Edwin walks?

Answers

The mixed number form is 6 2/3
The decimal form is 6.6
The exact form is 20/3

Answer:

The total distance is 41/9 = 4 5/9 miles

Step-by-step explanation:

Total time is 2 1/2 hours.  

First hour, he walks 1 2/3 = 5/3 miles.

Second hour, he walks 1 3/4 = 7/4 miles.

The last half hour he walks 1/4 of total distance. If we call total distance x.

[tex]\frac{5}{3} + \frac{7}{4} +\frac{x}{4} = x[/tex]

Now, we can eliminate the denominator, multiplying by four and by three.  

[tex]5*4 + 7*3 + 3*x = 4*3*x\\20 + 21 + 3x = 12 x\\41 +3x = 12x \\41 = 12x - 3x\\41 = 9x\\x = 41/9\\x = 4 \frac{5}{9}[/tex]

Total distance is 4 5/9 miles

John made $195 for 13 hours of work. At the same rate, how much would he make for 17 hours of work?

Answers

Final answer:

John's hourly wage is calculated to be $15 per hour. For 17 hours of work at this rate, John would earn $255.

Explanation:

John made $195 for 13 hours of work, which means his hourly wage is the total amount earned divided by the total hours worked. To find John's hourly wage we calculate $195 ÷ 13 hours = $15 per hour. To determine how much he would make for 17 hours of work at this same rate, we multiply his hourly wage by 17 hours.

$15 per hour × 17 hours = $255

Therefore, at the same hourly rate, John would make $255 for 17 hours of work.

The temperature was 29*F. By the end of the day, the temperature dropped TO -7*F. what was the total distance in the temperature change?

Answers

change in temp is just the maginitude of the difference between the two temperatues

|delta T|

=|T2-T1|  OR |T1-T2|(same answer)
=|-7-21|

=28
It dropped from 29 to -7

So going from 29 to 0, is a total of a 29 degree change.
And then going from 0 to -7 is a total of a 7 degree change.

Thus the total change in temperature is 29 + 7 = 36.

We need to find the factors of the expression.

Factors: Numbers and variables multiplied to get an expression, then these numbers and variables are known as factors.

The factor form of given expression is

[tex]\frac{6}{7}cd=\frac{6}{7}\times c\times d[/tex]

Therefore, the factors of the expression are 6/7, c and d.

D is the correct answer its the least common denominator!!
The answer to your question is C, and D. The way that you get this is by multiplying. To get 20, you multiply 2/5 by 4 to get 8/20, and you multiply 3/10 by 2 to get 6/20. To get 10 as a denominator for 2/5 you multiply by 2/5 to get 4/10, and you do not have to do anything to the 3/10 because the denominator is already 10. Then you just compare the numbers on the top to determine the larger fraction.

The perimeter of a rectangle is 24 inches. Find the dimensions if it’s length is 3 inches greater than its width

Answers

2l+2w=24
l=3+w
The first equation comes from the perimeter formula. Since it is a rectangle, there are two lengths and two widths, which must all be added to get the perimeter.  The second equation shows that the length is equal to the width plus three.  In order to solve this equation, the substitution method should be used, since the one equation is already set equal to one of the variables (L)

2l+2w=24
l=3+w

2(3+w)+2w=24
Use distributive property to get rid of the parentheses
2(3+w)+2w=24
2(3)+2(w)+2w=24
6+2w+2w=24
Simplify like terms on the left side of the equation
6+2w+2w=24
6+4w=24
Subtract six from each side so that all of the w's are on one side
6+4w-6=24-6
4w=18
Divide each side by four to find the value of one w
4w/4=18/4
w=4.5
Plug 4.5 into the one equation to find the value of l
l=3+4.5
l=7.5
Put the numbers into the first equation and simplify:
2(7.5)+2(4.5)=24
15+9=24
24=24
So the length would be 7.5 inches, and the width would be 4.5 inches

There are three liters Of apple juice at a school party. 10 students want to drink all of the apple juice, and they all want to get exactly the same amount. How much apple juice can each student have?

Answers

To calculate the amount of apple juice each of the 10 students can have, divide the total volume of 3 liters by 10, resulting in 0.3 liters per student.

The question involves dividing a total volume of liquid evenly among a number of participants, which is a basic arithmetic problem in mathematics, specifically dealing with division.

To find out how much apple juice each student can have, you need to divide the total amount of apple juice by the number of students. There are 3 liters of apple juice and 10 students. So, each student can have 3 liters / 10 students = 0.3 liters of apple juice. A liter is a unit of capacity, and it's comparable to a jug of milk or a bottle of soda, which also holds a similar amount of liquid. Hence, the volume in this context is measured in liters. When you divide the total volume of apple juice by the number of students, you get the volume that each student will receive.

Answers

Answer:

Mixed number is [tex]4\frac{7}{8}[/tex] and the simplified form of this mixed number is [tex]\frac{39}{8}[/tex].

Step-by-step explanation:

The two mixed numbers are

[tex]-3\frac{1}{4}=-\frac{13}{4}[/tex]

and [tex]-1\frac{1}{2}[/tex]

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

Now we will multiply these negative fractions.

[tex](-\frac{13}{4})(-\frac{3}{2})[/tex]

When two negative signs get multiplied they become positive.

= [tex]\frac{13}{4}\times \frac{3}{2}[/tex]

= [tex]\frac{39}{8}[/tex]

= [tex]4\frac{7}{8}[/tex]

Therefore, mixed number is [tex]4\frac{7}{8}[/tex] and the simplified form of this mixed number is [tex]\frac{39}{8}[/tex].

Grandma Jean is preparing the turkey for Thanksgiving dinner.The turkey weighs 12 lbs and there will be a total of 18 people at sinner.If each person eats the same amount of turkey,how much turkey will each person get

You'd take the total amount of turkey and divide it by the number of people. 12/18 = 0.6666 lbs or 2/3 of a pound per person. 20 lbs per person makes no sense as we start out with only 12 (also can you imagine 18 people each eating 20 pounds of turkey for thanksgiving? That'd be kinda gross).

which represents the tide in Dark Sea and t represents the time in hours.

We need to find the height of the tide after 6 hours.

For t = 6, we need to find the value of function f(t)

[tex]\Rightarrow f(6)=5\times cos((\frac{\pi}{4} )6)+11\\\\\Rightarrow f(6)=5\times cos((\frac{3\pi}{2} ))+11\\\\\Rightarrow f(6)=0+11\\\\\Rightarrow f(6)=11[/tex]
