find the slope of the line

Answer:

7. [tex]r^{19}[/tex]

Step-by-step explanation:

r^11 x r^8 =

r^11 + 8=

2^19

Answer:

A

Step-by-step explanation:

Δ NLP and Δ NMO are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{NL}{NM}[/tex] = [tex]\frac{NP}{NO}[/tex] , substitute values

[tex]\frac{15+x}{15}[/tex] = [tex]\frac{28}{20}[/tex] ( cross- multiply )

20(15 + x) = 420 ( divide both sides by 20 )

15 + x = 21 ( subtract 15 from both sides )

x = 6

Answer: 3,750 miles

Step-by-step explanation:

Route takes him 125 miles each way so in a day he travels:

= 125 + 125

= 250 miles

He made 15 roundtrips so total miles is:

= 15 * 250

= 3,750 miles

Answer:

I believe that B is the correct answer!

Step-by-step explanation:

The (x+5) can cancel

Then in the numerator (x^2-25) can be factored into (x-5)(x+5) through difference of squares.

Then in the denominator the (x-5)^2 can be stretched out to (x-5)(x-5)

Lastly the (x-5) on the top and bottom will cancel resulting in result B

I hope this helped!

Answer:

B(lol the one you chose randomly was right)

5, sorry I dunno the second number...

Step-by-step explanation:

(x+5)(x+5)(x-5)/ (x+5)^2(x-5)^2

(x+5)^2 gets canceled out

(x-5)/(x-5)^2

1/x-5

Answer:

x=7

y=5

Step-by-step explanation:

quadrilaterals have 360 degrees, and their opposite angles are equal

15x+5=16x-2

7=x

(plug back in to find angle)

15(7)+5=110

that angle, plus opposite angle, equals 110.

360-220=140

140/2=70

now we know the value of other unsolved angle

70=12y+10

60=12y

5=y

Answer:

2.5x10^3= 2,500

5x10^6= 5,000,000

Step-by-step explanation:

Here is a great trick that I always keep in mind whenever you are squaring 10 you add that many zeros for example.

10^4= 10000 (there are 4 zeros).

Answer:

x = 72

Answer:

The first one and the last one are true (Since −6 is 6 units to the left of 0, |−6|=6 and −6 is closer to zero on the number line than −7, so |−6|<|−7|.)

Step-by-step explanation:

Absolute value is the distance to zero, and it is always positive. That means the positive and negative versions of a number have the same absolute value. That means the first one is true, and the second and third ones are false. For the last one, -6 is closer to zero, so that means it would be true (The absolute value of -6 is 6, and the absolute value of -7 is 7).

8)  Onaje is correct

9a) answers could be:  3(6y) or 4y + 6y + 8y  or 2(2y + 3y + 4y)

 b) all answers simplify to be 18y

Step-by-step explanation:

Paula is not correct because 16t + 9t ≠ 16 + 9 + 2t

16t + 9t only equals 25t

Answer:

8. Onaje's expression is correct.

Step-by-step explanation:

The price, t, of the medium T-shirts can be represented as 16t, or 16 × t.

The price, t, of the large T-shirts can be represented as 9t, or 9 × t.

16t + 9t = (16 + 9) × t = 25t

Answer:

9. Part a: The expression could be 9y - 3y + 12y.

9. Part b: 9y - 3y = 6y

               6y + 12y = 18y

Answer:

[tex]\displaystyle \sin\theta=\frac{4}{5}[/tex]

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of a right triangle is called the hypotenuse and the other two sides are the legs.

Selecting any of the acute angles as a reference, we identify an adjacent leg and an opposite leg. The trigonometric ratios are defined upon those sides.

Sine Ratio

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

Let's focus on the angle θ. Its opposite leg is 8 cm and the hypotenuse is 10 cm, thus:

[tex]\displaystyle \sin\theta=\frac{8}{10}[/tex]

Simplifying:

[tex]\boxed{\displaystyle \sin\theta=\frac{4}{5}}[/tex]

Answer:

3600 tickets were sold for the musical performance.

Step-by-step explanation:

Given that:

Number of people seated for musical performance = 108

Percent to people to arrive yet = 97%

It means that the people who have already come are 3%.

Let,

x be the number of tickets sold.

3% of x = 108

[tex]\frac{3}{100}x=108\\[/tex]

0.03x = 108

Dividing both sides by 0.03

[tex]\frac{0.03x}{0.03}=\frac{108}{0.03}\\x=3600[/tex]

Hence,

3600 tickets were sold for the musical performance.

Answer: 63 nurses and 14 doctors

so you know the ratio is 9:2. that means for every 9 nurses there are 2 doctors. i didn't make an equation but i counted it.

if theres 9 (9*1) nurses theres 2 (2*1) doctors

if theres 18 (9*2) nurses theres 4 (2*2) doctors

if theres 27 (9*3) nurses theres 6 (2*3) doctors

you get the point so i multiplied 7 to 9 and 7 to 2, which means:

if theres 63 (9*7) nurses theres 14 (2*7) doctors

i hope this helps :)

Answer: 6%

Step-by-step explanation:

Number of students that wore a silly hat = 33

Number of students that students that did not = 517

Total number of students = 33 + 517 = 550

The percentage of the students that wore a silly hat

= 33/550 × 100

= 6%
