Please help!!! Angles!
Answer:
m∠JKM = 63°
m∠MKL = 27°
Step-by-step explanation:
Since ∠JKL is a right angle. This means that by summing up both m∠JKM and m∠MKL will result in the same as ∠JKL figure. Thus, m∠JKM + m∠MKL = m∠JKL which is 90° by a right angle definition.
\(\displaystyle{\left(12x+3\right)+\left(6x-3\right) = 90}\)
Solve the equation for x:
\(\displaystyle{12x+3+6x-3 = 90}\\\\\displaystyle{18x=90}\\\\\displaystyle{x=5}\)
We know that x = 5. Next, we are going to substitute x = 5 in m∠JKM and m∠MKL. Thus,
m∠JKM = 12(5) + 3 = 60 - 3 = 63°
m∠MKL = 6(5) - 3 = 30 - 3 = 27°

Answer:
The highest rate of birds is during the years 4 to 3
(remember that the lowest digit of number of negative is the highest and the highest is the lowest)
Step-by-step explanation:
Rate of Changes:
1 to 2: 5080.86 - 5238/ 2 - 1
= -157.14/1
= (convert to decimal) -157.1
2 to 3: 4928.43 - 5080.86/ 3 - 2
= -152.43/ 1
= -152.43

Mark thinks the equation y = 4+6x will match the red solid graph. Mia thinks it will match the blue dotted graph. who's right?
For the equation:
\(y=4+6x\)Identify the slope and the y-intercept by comparing with the general equation of a line with slope m and y-intercept b:
\(y=mx+b\)The slope of the given equation is equal to 6, and the y-intercept is equal to 4.
Both Mia and Mark agree that the y-intercept is equal to 4, but the slopes of the lines are different.
Notice that the red line has a negative slope, so, by no means that would be the graph of y=4+6x.
Observe that for a change of 1 step over the X-axis, the dotted line has an increase of 6 units over the Y-axis. You can look at the values for x=-1 and x=0. Therefore, the dotted line has a slope of 6 and a y-intercept equal to 4, which are precisely the values given by the equation.
Therefore, Mia is right.
Solve the following right triangle by finding all of the missing sides and angles. Round your answers to the nearest hundredth. B = 83.7°, C = 90°, and b = 3.21 km
The missing sides and angles of the right triangle are: side a ≈ 0.35 km, side c ≈ 3.28 km, and angle A ≈ 6.3°.
What are the missing sides and angles of the right triangle?To solve the right triangle with given angles B = 83.7°, C = 90°, and side b = 3.21 km, we can use trigonometric ratios and the Pythagorean theorem.
Angle B = 83.7°
Angle C = 90°
Side b = 3.21 km
Find angle A
Since the sum of angles in a triangle is 180°, we can find angle A:
A = 180° - B - C
A = 180° - 83.7° - 90°
A = 6.3°
Find side a using the sine ratio
The sine ratio is defined as the length of the side opposite the angle divided by the length of the hypotenuse:
sin(A) = a / b
a = b * sin(A)
a = 3.21 km * sin(6.3°)
a ≈ 0.35 km (rounded to the nearest hundredth)
Find side c using the Pythagorean theorem
The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides:
c² = a² + b²
c² = (0.35 km)² + (3.21 km)²
c² ≈ 10.74 km²
c ≈ 3.28 km (rounded to the nearest hundredth)
Therefore, the missing sides and angles of the right triangle are:
Side a ≈ 0.35 km
Side c ≈ 3.28 km
Angle A ≈ 6.3°

e. $2497.50
HELP NEEDED RIGHT AWAY PLS DUE NOW!!!!
Answer:
D
Step-by-step explanation:
250/9.99=25.0250... Round it to 25.03
The required converted value is $25.03, which is 250 pesos to U. S. dollars.
As we all know, unit conversion is the process of multiplying a provided quantity by a conversion factor that combines the two interconnected units.
To convert 250 pesos to U.S. dollars, we divide the amount of pesos by the exchange rate.
Here, the exchange rate is given as 9.99 pesos per U.S. dollar.
It is the process of assigning a quantity from one unit of measurement to another.
250 pesos / 9.99 pesos per U.S. dollar = 25.025 U.S. dollars
Rounding this to two decimal places, the conversion is approximately $25.03.
Therefore, the correct option is (d) $25.03.

There are 5 positions available in the new school. Of the applicant, 12 are men and 8 are women. In how many ways can 3 men and 2 women be chosen if they are equally considered?
There are 3080 ways 3 men and 2 women can be chosen if they are equally considered, using the multiplication principle of counting
What is the multiplication principle of countingThe multiplication principle states that if there are m ways to perform one task and n ways to perform another task, then there are m x n ways to perform both tasks together.
To find the number of ways to choose 3 men from the 12 men, we can use the formula for combination, which is: ⁿCᵣ = n! / (r! (n-r)!).
where n is the total number of men and r is the number of men chosen
so, the number of ways to choose 3 men from the 12 men = ¹²C₃ = 1.
Similarly, we evaluate the number of ways to choose 2 women from the 8 women
as = ⁸C₂ = 14
Now, using the multiplication principle, we can find the total number of ways 3 men and 2 women be chosen if they are equally considered.
220 x 14 = 3080
Therefore, there are 3080 ways 3 men and 2 women can be chosen if they are equally considered, using the multiplication principle of counting

Step-by-step explanation:
you have one rectangle "at the base"
S = b × h = 2ft × 6ft = 12 ft²
one rectangle "at the back"
S = b × h = 2ft × 10ft = 20 ft²
one rectangle "along the length of the hypotenuse"
S = b × h = 2ft × 8ft = 16 ft²
and two triangles
S = (b × h) / 2 = (6ft × 8ft)/2 = 24 ft²

Surface area for the prism = all the area's from the net added up.
Area triangle = 1/2 bh b=base, we need to find h, height=C=8
Use pythagorean to find base
c²=a²+b2
D² = C² + b²
10² = 8² + b²
b² = 100-64
b² = 36
b = 6
Area triangle = 1/2 (6)(8)
Area triangle = 24
Area of top rectangle = LW
L, length = A = 2
W, width = C = 8
Area of top rectangle = (2)(8)
Area of top rectangle = 16
Area of bottom rectangle = LW
L, length = A = 2
W, width = B = 6
Area of bottom rectangle = (2)(6)
Area of bottom rectangle = 12
Surface Area = 2(triangle) + (top rectangle) + (bottom rectangle)
Surface Area = 2(24) +16 +12
Surface Area = 48 +28
Surface Area = 76 ft²

11. What is the area of the triangle ABC if a=4, b= 7, and B= 75°?
If a=4, b= 7, and B= 75°, the area of triangle ABC is approximately 13.476 square units.
To find the area of triangle ABC given the values of a, b, and B, we can use the formula:
Area = (1/2) * a * b * sin(B)
where a and b are the lengths of two sides of the triangle and B is the angle between them, measured in degrees.
Substituting the given values, we get:
Area = (1/2) * 4 * 7 * sin(75°)
Using a calculator to evaluate the sine of 75°, we get:
Area = (1/2) * 4 * 7 * 0.96593
Area ≈ 13.476 square units

Suppose y varies inversely with x, and y = 49 when x = 17
. What is the value of x when y = 7 ?
Answer:
119 is the value of x when y = 7
Step-by-step explanation:
Since y varies inversely with x, we can use the following equation to model this:
y = k/x, where
k is the constant of proportionality.Step 1: Find k by plugging in values:
Before we can find the value of x when y = k, we'll first need to find k, the constant of proportionality. We can find k by plugging in 49 for y and 17 for x:
Plugging in the values in the inverse variation equation gives us:
49 = k/17
Solve for k by multiplying both sides by 17:
(49 = k / 17) * 17
833 = k
Thus, the constant of proportionality (k) is 833.
Step 2: Find x when y = k by plugging in 7 for y and 833 for k in the inverse variation equation:
Plugging in the values in the inverse variation gives us:
7 = 833/x
Multiplying both sides by x gives us:
(7 = 833/x) * x
7x = 833
Dividing both sides by 7 gives us:
(7x = 833) / 7
x = 119
Thus, 119 is the value of x when y = 7.
The quotient of y and 6 is 29 find the value of y
Answer:
Addition → 23
Since 29 is a prime number and does not have least common factors beside itself and 1, there is only addition here, which would be 23 + 6.
Answer:

Step-by-step explanation:
If y/6 is 29, we need to do an inverse operation to find Y.
The inverse operation of division is multiplication.
29*6=174
