Mr. Thompson cut the grass on the golf course in 1683 minutes.

We know that in one hour, there are 60 minutes. Then the number of hours that it takes to cut the grass will be given as,

⇒ 1683 / 60

⇒ 28 + 1/20

For this case we have the following quadratic function:

[tex]f (x) = x ^ 2 + x-6[/tex]

We must find its roots. We can factor, looking for two numbers that when added to +1 and multiplied by -6. These are:

Step-by-step explanation:

Every state has different requirements for obtaining a high school diploma. And each school varies greatly in what type of classes they offer. There are, however, a number of classes that are available, and perhaps even mandatory, in most high schools.

The courses your teen takes will also vary depending on his plans beyond high school. Students who plan to go to college may be required to take more years of a foreign language. Or a student who plans to major in engineering may want to take more math and science classes to prepare for college.

Students in a vocational track may be able to gain some hands-on learning. Many of them are even able to gain certificates or licenses that will help them in their future careers.

It's important to talk to your teen about her aspirations. Help her explore various career options.

Also, talk about what courses she plans to take in high school. Discuss her interest areas and review her schedule together. In addition to the basic classes, there are usually plenty of opportunities for your teen to take electives in various areas of study.

Answer: Residuals and scatter plots and other stuffs.

I think that 2/4 would be bigger because 2/4 is the same as 1/2 and 1/2 is bigger than 1/8. Imagine a pizza, if i have 1/2 of a whole pizza i would have more pizza than a friend who had 1/8 of the whole pizza.

I hope this helps :)

If you simplify 2/4, you will get 1/2. 1/2 is bigger than 1/8.

Proof:

Draw 2 mental circles in your head. then draw lines that will make the circles out of 2 and out of 8. Now color in 1/2 of the first circle and 1/8 of the second circle. You can see that the 1/2 is bigger than the 1/8.

Answer:

8(157x^6 - 1)

Step-by-step explanation:

1256x^6 - 8

Start by factoring out a common factor. 1256 and 8 are both divisible by 8.

1256x^6 - 8 = 8(157x^6 - 1)

157 is prime, so 157x^6 - 1 is not factorable.

Answer: 8(157x^6 - 1)

Answer:

346 square inches

Step-by-step explanation:

Let's say you have a piece of paper that measures 2.3 inches by 2 inches.the area is 4.6 square inches. The closest whole number is 5, so rounded to the nearest square inch is 5 square inches. Fractions equal to half or greater get rounded up to the next whole number. Fractions less than half get rounded down. SO that means that 346.49 should be rounded down to just 346 although it may be almost 50.

Answer:

0.3

Step-by-step explanation:

In the bag are 12 red, 10 blue, 15 white, and 13 black marbles.

So total = 12 + 10 + 15 + 13 =  50 marbles

The probability he pulls a white marble = 15/50 = 0.3

Simplify the radical 75 first:

Given a rectangle with a perimeter of 24 ft where the length is 4 ft longer than the width, we find that the length is 8 ft and the width is 4 ft by setting up and solving an equation based on the formula for the perimeter of a rectangle.

The subject of this question is about finding the length and width of a rectangle given the perimeter and a relationship between the length and width. The formula for the perimeter of a rectangle is 2 * (length + width). If a rectangle has a perimeter of 24 ft, and the length is 4 ft longer than the width, we can add the length and width together and multiply by 2 to calculate the perimeter.

Let's call the width 'w'. Then the length will be 'w + 4'. From the information given, we have:

Therefore, the width of the rectangle is 4 ft. This means that the length, which is 4 ft longer than the width, is 4 + 4 = 8 ft. So the length of the rectangle is 8 ft.

Answer:

n = 28

Step-by-step explanation:

3/4n - 18 = 1/4n - 4 (eliminate fractions by multiplying each value by 4)

(3/4n * 4) - (18 * 4) = (1/4n * 4) - (4 * 4)

3n - 72 = 1n - 16 (move values with variable to same side)

3n - 1n - 72 = 1n - 1n -16

2n - 72 = -16 (move numeric values to same side)

2n - 72 + 72 = -16 + 72

2n = 56  (isolate n by dividing out the 2)

2n/2 = 56/2

n = 28

Simplif 1/2t to t/2

t/2 + 8 = 5/2t - 10

Simplify 5/2t to 5t/2

t/2 + 8 = 5t/2 - 10

Multiply both sides by 2

t + 16 = 5t - 20

Subtract t from both sides

16 = 5t - 20 - t

Simplify 5t - 20 - t to 4t - 20

16 = 4t - 20

Add 20 to both sides

16 + 20 = 4t

Simplify 16 + 20 to 36

36 = 4t

Divide both sides by 4

36/4 = t

Simplify 36/4 to 9

9 = t

Switch sides

t = 9

Answer:

t = 9.

Step-by-step explanation:

1/2 t + 8 = 5/2 t - 10

         - 8      -5/2 t

1/2 t - 5/2 t   =   -10 - 8

-2t = -18

t = 9.

Just like before, we can conclude that the scale factor is

B.

Answer

6 inches separate the cities on the map

Explanation

We know that our scale factor is 1/4 inch = 1 mile, so we can create a conversion factor to convert 24 miles to inches. Since we need to convert from miles to inches, the denominator of our conversion factor must be 1 mile so we can cancel miles out. Notice that we can also express 1/4 inch as 0.25 inch to simplify our calculations:

We can conclude that if the conversion factor is 1/4 inch = 1 mile, 6 inches separate the cities on the map.

Equation that can find the value of the car on December 31, 2017 is:

A= 25000*(1-0.15)^7 and the value of car after 7 years is $8014.427.

Step-by-step explanation:

Price of car = $ 25,000

Rate of depreciation = 15 %

Formula used:

A= P(1-r)^n

where p= price of car

A= new price of car after depreciation

r = rate of depreciation i.e. 15/100 = 0.15

n= time in years 2017 - 2010 = 7 years

Putting values in formula:

A= 25000*(1-0.15)^7

A= 25000*(0.85)^7

A= $8014.427

So, Equation that can find the value of the car on December 31, 2017 is:

A= 25000*(1-0.15)^7 and the value of car after 7 years is $8014.427.

Answer:

The pattern is pretty clear. After $n$ years, in $200n$ the price will be:

$a_n= a_0(0.85)^{n-1}$

Step-by-step explanation:

Answer:

7. 46.39 miles

8. 109 cm

9. 18 cm

Step-by-step explanation:

7. Look at the attached picture so you can picture the scenario.

The distance from City A to City B is 85 miles North. Notice that the plane only got to travel 20 miles North because of a cloudbank and redirected 108 degrees NORTH OF EAST, 20 miles towards that direction.

The new path makes a triangle, as shown in the picture.

The angle of the triangle was solved this way.

108° - 90° = 18°

The length of a was solved by getting how many miles the plane didn't travel in its original path.

85 miles - 20 miles = 65 miles.

So now we have our new given:

a = 65 miles

b = 20 miles  

c = ?

C = 18°

Using the cosine law we can solve for the c, which is the distance of the plane from City B.

[tex]c^{2}=a^{2}+b^{2}-2abCosC\\\\c^{2}=65^{2}+20^{2}-2(65)(20)Cos18\\\\c^{2}=4225+400-2600(Cos18)\\\\c^{2}=4625-2472.75\\\\\sqrt{c^{2}}=\sqrt{2152.25}\\\\c=46.39miles[/tex]

8. Again look at the attached. So as you can see we make another triangle. We can solve this with the cosine law once again. Just remember that the longer diagonal is opposite the biggest angle.

Given that:

a = 54cm

b = 78 cm

C = 110°

[tex]c^{2}=a^{2}+b^{2}-2abCosC\\\\c^{2}=54^{2}+78^{2}-2(54)(78)Cos110\\\\c^{2}=2916+6084-8424(Cos110)\\\\c^{2}=9000-(-2281.18)\\\\\sqrt{c^{2}}=\sqrt{11881.18}\\\\c=109cm[/tex]

9. Again, the shorter diagonal is facing the smaller angle. But we use the same cosine law to find it, but we use the formula of a, since a is what we are missing.

Given that:

a=?

A = 58°

b = 21cm

c= 15cm

[tex]a^{2}=b^{2}+c^{2}-2bc(CosA)\\\\a^{2}=21^{2}+15^{2}-2(21)(15)(Cos58)\\\\a^{2}=441+225-630(Cos58)\\\\a^{2}=666-333.85\\\\\sqrt{a^{2}}=\sqrt{332.15}\\\\a = 18cm[/tex]
