Since K is in the interior of the angle, this means we can use the angle addition postulate. 

Angle LMN = (angle LMK) + (Angle KMN)
Angle LMN = (52 degrees) + (12 degrees)
Angle LMN = (52 + 12) degrees
Angle LMN = 64 degrees

See the attached figure for an example of what this could look like.

how to solve this question


b/5-1=10

Answers

Our goal is to isolate the variable, which is b. What you do to one side must also be done to the other side since we need to maintain equality.

Add 1 to both sides
b/5=11

Then multiply both sides by 5
b=55

Final answer: b=55

What is the y-intercept of the equation of the line that is perpendicular to the line y = x + 10 and passes through the point (15, –5)?

The equation of the line in slope-intercept form is y = x +

Answers

y = x + 10 has slope = 1
perpendicular lines, slope is opposite and reciprocal
so perpendicular line slope = -1
passes through the point (15, –5)
y = mx + b 
-5 = -1(15) + b
b = -5 + 15
b = 10 
y -intercept : 10

The equation of the line in slope-intercept form is y = -x + 10

1. Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. Happy Hounds charges a flat fee of $21 plus $1 per hour. For how many hours is the total fee charged by the companies the same?

Answers

x represents the amount of hours
peppy pets 15 + 3x
happy hounds 21 + x

15 + 3x = 21 + x
subtract x from both sides

15 + 2x = 21
subtract 15 from both sides

2x = 6
divide each side by 2

x = 3 hours


Algebraic equations are equations that consist of unknown variables. These variables can be represented using the letters of the alphabet.

The total fee charged by the companies will be the same in 3 hours.

Let's represent the number of hours as :h

Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. The algebraic equation to represent this statement is given as:

$15 + $3 x h

15 + 3h ..........Equation 1

Happy Hounds charges a flat fee of $21 plus $1 per hour. The algebraic equation to represent this statement is given as:

$21 + $1 x h

21 + h ..........Equation 1

We equate both equations to each other

Equation 1  = Equation 2

15 + 3h  = 21 + h

Collect like terms

3h - h = 21 - 15

2h = 6

Divide both sides by 2

2h/2 = 6/2

h = 3

Therefore, the total fee charged by the companies will be the same in 3 hours.

Ashely walks 2 1/2 miles around a lake around three times a week. If Ashley walks around the lake in 3/4 hour,what is her rate of speed? (Hint: Use the formula r= d/t, where the r is rate, d is distance, and t is time.

Answers

To find Ashley's rate of speed in miles per hour, you will use the formula

Rate = Distance/Time.

First, you should fill in what you know. In this case, you know the distance is 2.5 miles, and the time is 0.75 hours. Now, you simply plug in the known variables to the formula to get Rate = 2.5 miles / 0.75 hours. After dividing, you reach the answer Rate = 3.333333 (or 3 and 1/3) miles/hour.

Let C, S and H be the diameters of cell, sand and hair


Diameter of a cell: [tex] C=1 \cdot 10^{-5}m[/tex]

Diameter of a grain of sand: [tex]S=2 \cdot10^{-4}m[/tex]

Part A:

[tex]H=0.000025=2.5 \cdot 10^{-5}[/tex] meters, because it takes 5 movements right of the decimal dot, until there is only one digit to its left.

Part B:

we are comparing [tex]S=2 \cdot10^{-4} m [/tex] to [tex] C=1 \cdot10^{-5} m [/tex] ,

[tex] \frac{S}{C}= \frac{2 \cdot 10^{-4}}{1 \cdot 10^{-5}}=\frac{20 \cdot 10^{-5}}{1 \cdot 10^{-5}}=20[/tex]

thus S is 20 times larger than C

Part C

[tex]1m=1 \cdot10^9nm[/tex]

thus,

[tex]H=2.5 \cdot 10^{-5}m=2.5 \cdot 10^{-5} \cdot 1 \cdot 10^9nm=2.5 \cdot 10^{-5+9}=2.5\cdot10^4nm[/tex]

Part D.

[tex]1m=1\cdot 10^9nm\\\\1nm=\displaystyle{ \frac{1m}{10^9}=1\cdot 10^{-9}m} [/tex]

thus 300 nm are written in meters as follows:

Hollis and Charmaine are curious about which mode of transportation gets them from their apartment to the mall faster. Hollis takes public transportation and gets to the mall in 18.5 minutes. Charmaine rides her bike and gets to the mall in 0.5 hours. The mall is 2.4 miles away from their apartment. Use the formula for distance traveled, distance=rate⋅time, to find each rate of travel in miles per minute. What is the difference between Hollis' rate of travel on the bus and Charmaine's rate of travel on the bike? In other words, how much faster is it to take the bus in miles per minute? Enter your answer as a decimal, rounded to the nearest hundredth, if necessary, like this: 42.53 50 pts

Answers

Hollis travels 0.05 miles per minute faster than Charmaine. First, convert to the same units for both Hollis and Charmaine. So Hollis takes 18.5 minutes and Charmaine takes 0.5*60 = 30 minutes. Both girls travel 2.4 miles, so calculate how many miles per minute each takes Hollis = 2.4 / 18.5 = 0.13 miles per minute. Charmaine = 2.4 / 30 = 0.08 miles per minute. Finally determine the difference in speed between the two girls. 0.13 - 0.08 = 0.05 miles per minute.

Jesse and three friends buy snacks for a hike. They buy trail mix for $5.42, apples for $2.55, and granola bars for $3.99. If the four friends split up the cost of the snacks equally, how much should each friend pay?

Answers

2.99 because you add the total cost up, which would be 11.96. So then you would divide 11.96 by 2.99 which gives you 2.99


Add all the numbers up which equals up to 11.96. Then divide 11.96 into 4. it equals 2.99 so each friend is gonna pay 2.99

A scuba diver starts at 85.6 meters below the surface and descends until he reaches 103.2 meters below sea level. How many meters did he descend ?

Answers

188.8 meters because you have to add 103.2+85.6 = 188.8 meters
Final answer:

The scuba diver descended 17.6 meters.

Explanation:

To find the distance the scuba diver descended, subtract the starting depth from the ending depth. In this case, the starting depth is 85.6 meters below the surface and the ending depth is 103.2 meters below sea level. So, the distance the scuba diver descended is 103.2 - 85.6 = 17.6 meters.
