Can someone help me find m
Answer:
69 degrees
Step-by-step explanation:
m is a point, if your trying to find lkh, is 69
lkm=111, and jkl=180, so 180-111=jkm
jkm=69
angles that are diagonal from each other are the same degree
lkh=69
hope this helps, if not see me in the commnets
HOPE THIS HELPS, BRAINLIEST PLEASE
Answer:
m < LKH = 69°
Step-by-step explanation:
Given that m < LKM = 111° and that:
<LKM and <LKH are adjacent angles as they share the same vertex, point K, and same ray between them, KL:
Then we can assume that m < LKM and m < LKH are supplementary angles whose sum = 180°.
Therefore, we can establish the following equation:
m < LKM + m < LKH = 180°
111° + m <LKH = 180°
Subtract 111° from both sides to solve for m < LKH:
111° - 111° + m <LKH = 180° - 111°
m < LKH = 69°
Therefore, the measure of < LKH is 69°.

You can buy 5 cans for green beans at the Village Market for $2.70. You can buy 10
of the same cans of beans at Sam's Club for $6.50. Which place is the better buy?
Answer:
Village Market
Step-by-step explanation:
for this question we need to find the unit rate (the rate for one of something).
in this case, we need to find the cost of one can at each store so we can
easily compare the cost to see which one is cheaper
it would be (total cost)/(total number of cans)
Village Market = $2.7/5 = .54 cents per can
Sam's Club = $6.5/10 = .65 cents per can
Since Village Market has a cheaper price per can, it is the better buy.
Answer:
Village Market
Step-by-step explanation:
10 cans at the Village Market is = to $5.40.
But at Sam's Club 10 cans cost $6.50 witch is $1.10 more money your paying when u can save it.

Step-by-step explanation:
first of all, g(x) has only negative functional result values (y) except for 0.
and a square is always positive.
so, the only possible right answers are the ones that include a minus ("-") sign.
the graph shows us that g(x) goes through the points (1, -3) and (-1, -3).
so, which equation turns an x = 1 into an y = -3 ?
therefore, the right answer must be D.
g(x) = -3x²
it works for both points :
-3 = -3×1² = -3 correct
-3 = -3×(-1)² = -3×1 = -3 correct
15w^4 v^5 / 3w^6 v^5
Answer:
[tex]\frac{{5}}{w^{2}}[/tex]
Step-by-step explanation:
We begin with [tex]\frac{15w^{4}v^{5}}{3w^{6}v^{5}}[/tex].
Firstly, as with simplifying fractions we can simplify the numbers. 15 is divisible by 3, so this becomes [tex]\frac{5w^{4}v^{5}}{w^{6}v^{5}}[/tex].
To simplify indices (aka exponents or powers), we must subtract the power on the denominator from the matching one on the numerator, and then use that number as the power in the numerator. In this case, 4-6 and 5-5, which becomes -2 and 0.
So now we have [tex]\frac{5w^{-2}v^{0}}{1}[/tex].
For a negative power, we switch it into the other half (numerator to denominator) and take away the negative sign, leaving [tex]\frac{5v^{0}}{1w^{2}}[/tex].
We can remove the [tex]v^{0}[/tex] in the numerator as it just multiplies the numerator by one, and remove the 1 in the denominator for the same reason.
This leaves us with [tex]\frac{5}{w^{2}}[/tex].

An air traffic controller is monitoring the altitudes of four planes. The four equations below show y, the
distance in feet of each plane above the ground, after 6 minutes of descent. (Hint: Look at the slopes to help
you.)
Plane A: y = 400t + 12,000
Plane B: y = -800t + 28,000
Plane C: y = -200t +13,500
Plane D: y = -500t + 30,000
a. Which plane is descending at the slowest rate?
b. Which plane began its descent from the highest altitude?
Answer:
Step-by-step explanation:
a. Plane C has the slowest rate of descending.
b. Place D has begun to descend from the highest altitude.
What is the equation of a line in slope intercept form?The equation of a line in slope intercept form is y = mx + b where the slope is m and the y-intercept is b.
The altitude of four planes is represented by y after 6 minutes and t represents time in minutes.
To determine which plane is descending at the slowest rate we have to look for a slope in these four equations which is the least steep or which modulus value is the least.
If we take the modulus of all four slopes 200 is the least value.
∴ Plane C has the least descending rate.
To determine which plane starts descending from the highest altitude we look for the value of y-intercept which is the largest among them and that is plane D.

Write the equation of a line perpendicular to 5x−9y=−8 that passes through the point (−5,8).
Answer: y = -(9/5)x - 1
Step-by-step explanation:
Rewrite the equation in standard form: y = (5/9)x+(8/9). [y=mx+b]
A line perpendicular to this would have a slope that is the negative inverse of the original slope (5/9), which would make it -(9/5). The y-intercept would also change, but we don't know the value, yet. For now, we'll use "b" for the y-intercept. This results in a perpendicular line:
y = -(9/5)x + b
We can calculate b, the y-intercept, by using the point (-5,8) and solving for b.
8 = -(9/5)*(-5) + b
8 = (9) + b
b = -1
The line perpendicular to 5x−9y=−8 that passes through the point (−5,8) is
y = -(9/5)x - 1

At a farm the ratio of cows to horses was 9: 2 if there were 72 cows at the farm how many horses were there
Answer:
16 Horses!
Step-by-step explanation:
Since
9 : 2 = 72 : X
Then we know
2/9 = X/72
Multiplying both sides by 72 cancels on the right
72 × (2/9) = (X/72) × 72
72 × (2/9) = X
Then solving for X
X = 72 × (2/9)
X = 16
Therefore
9 : 2 = 72 : 16

Answer:
x=5
Step-by-step explanation:
Since these angles are vertical angles formed by two parallel lines being intersected by another vertical line, you can set the 18x and 17x+5 equal to each other. Then you solve using algebra. I hope this helps!
Answer:
x=5
Step-by-step explanation:
Because they both equal 90°, you can use the equations, 18x=90 and 17x+5=90 to solve.
First, 18x= 90: (Divide by 18)
x=5
Now, 17x+5=90: (Subtract 5 from both sides)
17x= 85
Then divide by 17:
x= 5

The sum of two numbers is 50 and the difference is 4
Step-by-step explanation:
let the 2 numbers be x and x + 4 as their deference is 4.
their sum = 50
now,
→ x + x + 4 = 50
→ 2x + 4 = 50
→ 2x = 50 - 4 = 46
→ x = 46/2 = 23
therefore two numbers are,
x = 23
x + 4 = 23 + 4 = 27
hope this answer helps you dear...take care and may u have a great day ahead!
Step-by-step explanation:
x + y = 50
x - y = 4
x = y + 4
let's use that as substitute in the first equation
y + 4 + y = 50
2y = 46
y = 46/2 = 23
=>
x = y + 4 = 23 + 4 = 27
the 2 numbers are 23 and 27.
