Answer 1

Answer: so the sheet is called: sets of real numbers
you have the sets
1.natural numbers
2. whole numbers
3. integers
4. rational numbers
5. irrational numbers

1. Natural number: counting numbers not including zero ex. 1,2,3,4...
2. whole numbers: natural numbers and zero ex. 0,1,2,3,4...
3. integers: whole numbers and their negative counterparts ex. -4,-3,-2,-1,0,1,2,3,4...
4. rational numbers: numbers that can be expressed as a/b where b is not equal zero ex 1/4, 3/1, 0/9...
5. irrational numbers: numbers that don't end ex. pi, (note, 0.3333333333333 doesn't count since it can be expressed as 1/3)

so we calculate them and put them into the proper set

1. -15
this is negative, so it is an integer

2. 11
this is a counting number so it is a natural number

3. squarerootof 30
if you calculate this you get a long number. I am not sure weather it ends or not so it could be irrational

4. 17/3
this is rational since it is in the form a/b

5. 6
this is counting so it is natural number

6. 0
this is a whole number

7. -13
this is negative, so it is an integer

8. 3
this is a counting number so it is anatural number

9. 10/11
this is rational since it is in theform a/b

10. 14
this is a counting number so it is anatural number

11. -13
we did this already on no.7
it's an integer

12. pi
this is irrational

13. 475/325
this is rational since it is in theform a/b

14. squarerootof 77
if you calculate this you get a longnumber. I am not sure weather it ends or not so it could beirrational

15. 6/7
this is rational since it is in theform a/b

16. squarerootof 0
this is a whole number because swuareroot of zero=zero

17. -squareroot 196
this is an integer since if you calculate it, it gives you -13

18. -1
this is negative, so it is an integer

so the answers are
1. Integer
2. Natural
3. Irrational
4. Rational
5. Natural
6. Whole
7. Integer
8. Natural
9. Rational
10. Natural
11. Integer
12. Irrational
13. Rational
14. Irrational
15. Rational
16. Whole
17. Integer
18. Integer

Parallelogram A B C D is shown. The length of A B is (9 x minus 14) inches and the length of D C is (3 x + 4) inches. In parallelogram ABCD, what is DC? (trust me) 13 in.

Answers

Answer:

$DC=13\ in$

Step-by-step explanation:

we know that

in a parallelogram, opposite sides are congruent

In this problem

AB and DC are opposite sides

therefore

AB=DC

substitute the given values

$9x-14=3x+4$

solve for x

$9x-3x=4+14\n6x=18\nx=3$

Find the length of side DC

$DC=3x+4$

substitute the value of x

$DC=3(3)+4=13\ in$

1 gallon minus 1 quart, 1 pint, and 1 ounce

Answers

Answer: 79 ounces = 2 quarts and 15 ounces.

Explanation:

1) The question is: 1 gallon - (1 quart + 1 pint + 1 ounce)

2) To add and subtract those amounts you have to convert all to one same unit.

3) Since the least unit is ounce, I will convert gallon, quart and pint to ounces.

4) Conversion factors:

1 gallon = 4 quart

1 quart = 2 pints

1 pint = 16 ounces

5) Conversions:

i) 1 gallon × 4 quart / gallon × 2 pint / quart × 16 ounce / pint = 128 ounces

ii) 1 quart × 2 pint / quart × 16 ounce / pint = 32 ounces

iii) 1 pint × 16 ounce / pint = 16ounces

4) Subtract:

1 gallon - (1 quart + 1 pint + 1 ounce) = 128 ounces - (32 ounces + 16 ounces + 1 ounce) = 128 ounces - 49 ounces = 79 ounces ← answer

You can convert it to a mixed number in this way:

79 ounces × 1 quart / 32 ounces = 2. 46875 quarts

0.46875 quarts × 32 ounces / quart = 15 ounces

Then, 79 ounces = 2 quarts and 15 ounces.

16 ounces = 1 pint
2 pints = 1 quart
4 quarts = 1 gallon

1 gallon - 1 quart = 3 quarts
3 quarts - 1 pint = 2 quarts and 1 pint
2 quarts and 1 pint - 1 ounce = 2 quarts and 15 ounces.

Skylar makes turkey sandwiches for a family reunion he purchases 5 lbs. 4 oz. of sliced turkey for $26.88 what is the unit cost per ounce for turkey skylar purchased

Answers

Answer:

$0.32

Step-by-step explanation:

The first step is to convert pounds to ounces.

1 lbs = 16 oz

so:

5 lbs = 5(16) ounces

5 lbs = 80 oz

Skylar bought 5 pounds and 4 ounces, and we already found that 5 pounds is 80 ounces, so she bought a total of

80oz + 4oz = 84 oz.

The price for these 84 ounces was $ 26.88, to find the unit cost per ounce of turkey, we divided the total cost by the amount of ounces:

$26.88 ÷ 84 = $0.32

the cost per ounce is $0.32

seth and Brian ran the 200 yard dash at the track meet. Brian reached the finish line in 30 seconds. Seth ran 25 feet per second. who finished the race first? explain your reasoning.

Answers

ok so we know that brian took 30 seconds to finish the race, but we don't know how long seth took. The problem told us the race was 200 yards and that seth ran 25 feet per second. From those two pieces of information, we can figure out how many seconds it took seth to run 200 yards. Since the problem told us he ran 25 FEET per second, we will convert the length of the track from yards to feet. There are 3 feet in a yard, so the track is 600 feet. Since he ran 25 feet per second, if we divide the length of the track by the speed he ran, we will get how long it took him to run. So 600 divided by 25 will give us 24 seconds. So Brian ran the race in 30 seconds and Seth ran it in 24, so Seth ran the race the fastest!
