Mason walks 9 miles in 2 hours. At what unit rate does Mason walk?

Answer:

11.21

Step-by-step explanation:trust me bro

Answer:

11.21

Step-by-step explanation:

Answer: 180.

Step-by-step explanation:

Appetizers = 5 types

drinks = 3 types

Sandwiches = 4 types.

Solution:

This is a combination problem.

For appetizers

= 5C2

= 10.

For drinks

= 3C2

= 3.

For sandwiches

= 4C2

= 6.

No. Of combinations scot can choose for his party

= 10*6*3

= 180

Scot can choose a total of 180 combinations for his party.

Answer:

There are no solutions.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x/5+2/3+1x/5=x

4/5x+2/3+1/5x=x

(4/5x+1/5x)+(2/3)=x(Combine Like Terms)

x+23=x

x+23=x

Step 2: Subtract x from both sides.

x+2/3−x=x−x

2/3=0

Step 3: Subtract 2/3 from both sides.

2/3−2/3=0−2/3

0=−2/3

Answer:

There are no solutions.

Answer:

x=-3

Step-by-step explanation:

You need to delete the root by ^2. First you need to leave it alone

[tex]\sqrt{x+7}-x=5\\\sqrt{x+7}=5-x\\(\sqrt{x+7} )^{2}=(5-x)^{2} \\x+7=25+10x+x^2\\x-10x=25+x^2-7\\-9x=18+x^2\\-x^2-9x-18=0\\-1(x^2+9x+18)=0\\x^2+9x+18=\frac{0}{-1}\\x^2+9x+18=0\\(x+6)(x+3)=0\\x+6=0 ===> x=-6\\x+3=0 ===> x=-3\\Checking\\\sqrt{-6+7}-(-6)=5===>\sqrt{1}+6=7\neq5 \\\\\sqrt{-3+7}-(-3)=5===>\sqrt{4}+3=5=5\\\\So \\x=-3[/tex]

Answer:

b = -3

Step-by-step explanation:

-6 = b2 is the same thing as -6 = 2b to be precise.  Divide 2 on both sides to get -3 as your b value.

Answer:

b= 9/2123

have a great day :)

Answer:

85 + 42x = 337

x = 6

Step-by-step explanation:

For the equation:

We know there is a one-time fee plus 42 times the number of days you rent the booth for and that the total of the equation should be 337 as that is the total she paid for. We start with the one-time fee (85) and add the county fair-grounds cost (42) multiplied by the number of days you rent the booth for. Since we don't know how many days that is, we will make that our variable which we will call x.

So far we have: 85 + 42x

Now we should set the equation equal to the total amount of money Ms. Williams paid.

This will give us: 85 + 42x = 337

To solve the equation:

Our goal is to find x since that is the number of days Ms. Williams rented the booth for.

First, we subtract 85 from both sides of the equation.

42x = 252

Then, we divide both sides by 42 to isolate our variable, x.

x = 6

X is the number of days Ms. Williams rented the booth for. Therefore, Ms. Williams rented a booth at the county fair for 6 days.

Answer:

3(x-2)=4x+1

or, 3x-6=4x+1

or, 3x-4x=1-6

or, -x= -5

or, x=5

Step-by-step explanation:

step 1. you need to multiply (x-2) by 3

step 2. you need to arrange the equation in proper term which is (3x-4x=1-6)

step 3.after that you need to solve it and answer in both sides will come out in minus (-) which is (-x= -5)

step 4. then the minus (-) on both sides will be canceled and the answer will be 5

Answer:

A: yes, measure of interior angle = 120

Step-by-step explanation:

120 can be divided with 360 without any remainders

if the total degrees can be divided by the interior angle degrees without any remainders, then it tessellates the plane.

Yes, The regular polygon tessellates the plane because the measure or interior angle = 120. hence, the option A is correct.

We know that 120 could be divided by 360 without having any kind of remainders.

So, in the case when the total degrees could be divided by the interior angle degrees so it should tessellates the plane

hence, the option a is correct.

Here is the full data for the question.

Each person in the state of Texas generate roughly 7.5 pounds of municipal solid waste each day. Of this amount, roughly 35 percent of the waste is currently recycle in Texas. Studies have shown that the maximum amount of waste that could be realistically recycled or otherwise diverted from the landfill is 50 percent.

(NOTE: for tons, use I ton -2,000 pounds unless otherwise specified)

11. For a community/service area of 200,000 people, calculate the amount:

Total MSW each year, in pounds?               ? Tons?              

II. Total MSW currently recycled each year, in pounds?               Tons?          

III Amount of the MSW that could realistically be diverted from the landfill if recycling was maximized to the nearest pound.

12. Using the current recycling rate, calculate the amount of MSW sent to a landfill over 15 years period to the nearest pound.

13. If a landfill has a density of 1,200 pounds per cubic yard, what would be the volume required for 15- years worth of MSW to the nearest cubic yard?

Answer:

Step-by-step explanation:

11)

I) The amount of total MSW generated per day in pounds is = 1,500,000 Pounds

The total MSW generated per day  in tons is = 750 Tons

The amount of the total MSW generated per year in pounds will be:

= 1,500,000 × 365

= 547,500,000 Pounds

The amount of the total MSW generated per year in tons is

= 750 × 365

= 273,750 Tons

II)

The amount of the total MSW currently recycled per day is pounds

= 1,500,000 × (35/100)

= 525,000 Pounds

Total MSW currently recycled per day in tons is

= 750 × 35/100

= 262.5 Tons

The amount of the total MSW currently recycled per year in pounds is

= 525,000 × 365

= 191,625,000 Pounds

The amount of the total MSW currently recycled each year in tons is

= 262.5 × 365

= 95812.5 Tons

III) The required amount of MSW which could realistically be diverted from the landfill suppose that the recycling was maximized (for each person) is

= 7.5 × (50/100)

= 3.75 Pounds

≅ 4 Pounds

The required amount of MSW which could realistically be diverted from the landfill suppose recycling were maximized (for the total population) is:

= 1,500,000 × (50/100)

= 750,000 Pounds

12)

Applying the current rate of recycling, the amount of MSW sent to landfill over a 15 year period (for each person) is:

= 7.5 × (100-35)/100

= 4.875 Pounds each day

= 4.875 × 365 × 15

= 26690.625 Pounds/ 15 years/person

≅ 26,691 Pounds/ 15 years/person

For 1 year period:

By applying the current rate of recycling, the required amount of MSW sent to landfill over (for total population) is:

= 547,500,000 × (100-35)/100)

= 355,875,000 Pounds

For 15 years period:

By applying the current rate of recycling, the amount of MSW sent to landfill  (for total population) is:

= 355875000 × 15

= 5,338,125,000 Pounds

13)

The volume required for the landfill for 15 years worth of MSW is:

= 5,338,125,000/1,200

= 4,448,437.5 Cubic yard

≅ 4,448,438 Cubic yard

Answer:

a) [tex]2n+14[/tex]

b) [tex]\frac{nx}{2}[/tex]

Answer:

2(a) 2n + 14

2(b) [tex]\frac{nx}{2}[/tex]

Step-by-step explanation:

For (a), all you have to do is interpret the question itself and turn it into a mathematical operation.

Firstly, as the question has given, the number in (a) should be n.

Therefore, twice of n is 2n, and the sum of 2n and 14 is 2n + 14.

Same goes for (b). The question says a number multiplied by x, meaning nx, and nx halved, getting [tex]\frac{nx}{2}[/tex].

Answer: 1%

Step-by-step explanation:

Given that :

Degree of freedom (df) = 21

What proportion of the area under the curve lies to the left of t = -2.518?

Using the online t value calculator :

P(t ≤ - 2.518) = 0.01

Hence, proportion of area under the curve which lies to the left of - 2.518 with degree of freedom (df = 21) is 0.01 = 1%
