In ΔKLM, k = 76 inches, l = 30 inches and m=69 inches. Find the measure of ∠M to the nearest degree. pleseeeeee
Answers
Answer: 65
Step-by-step explanation:
Measure of ∠M to the nearest degree is [tex]65^{0}[/tex].
What is law of cosine?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.
Given
k = 76 inches
l = 30 inches
m = 69 inches
From the law of cosines
Cos <M = [tex]\frac{k^{2} +l^{2} -m^{2} }{2.k.l}[/tex]
Cos <M = [tex]\frac{76^{2} +30^{2} -69^{2} }{2.76.30}[/tex]
Cos <M = [tex]\frac{1915}{4560}[/tex]
Cos <M = 0.42
<M = [tex]cos^{-1} (0.42)[/tex]
<M ≈ [tex]65^{0}[/tex]
Hence, measure of ∠M to the nearest degree is [tex]65^{0}[/tex].

If Kyle makes a zero on his ELA finals, and it counts for .01% of his 90.8%, how much will Kyle’s grade drop?
—
please help i’m not sure how to do math like this
Answers
Answer:
9.2 %
Step-by-step explanation:
Given: 0 on finals, overall is 90.8, then 0.01%
To find: How much of Kyle’s grade dropped
Solve: First, calculate the percentage you received on the test by dividing your mark by the total marks.
Kyle scored 0 out of 100, then 0/100 = 0 percent.
Secondly, multiply your percentage score on the test by the percentage it is worth of the final grade.
0 × 90.8 = 9.2 %
9.2 % of the final grade

an astronaut drops a rock off the edge of a cliff on the moon. the distance, d(t), in meters, the rock travels after t seconds can be modeled by the function d(t) = 0.8t^2. what is the average speed, in meters per second, of the rock between 5 & 10 seconds after it was dropped?
Answers
Answer:
The average speed between the times given is 12 m/s
Step-by-step explanation:
Here, we want to calculate rate of change between the times given
Mathematically , we can get the average rate of change using the formula
f(b)-f(a)/b-a
in this case, b = 10 s and a = 5 s
f(b) is d(10) = 0.8(10)^2 = 80
f(a) is d(5) = 0.8(5)^2 = 20
Rate of change is thus;
(80-20)/(10-5) = 60/5 = 12 m/s

The circle
Where, we have
Center = (a, b) = (2, -2)
Radius, r = 3 units
The equation of the circle graphed is represented as
(x - a)² + (y - b)² = r²
So, we have
(x - 2)² + (y + 2)² = 3²
Evaluate
(x - 2)² + (y + 2)² = 9

Which expression represents the approximate area of the circle in square inches? 9.42 times 3 9.42 times 3 squared 9.42 times 6 9.42 times 6 squared]
Answers
Answer:
The expression that represents the approximate area of the circle in square inches is;
9.42 times 3
Step-by-step explanation:
From the question, we have;
The shape of the figure which Kyra is finding the area for = A circle;
The number of equal pieces Kyra cuts the shape into = 8 equal sectors
The shape the sectors are arranged into = A parallelogram
The base of the parallelogram = 9.42 inches
The height of the parallelogram = 3 inches
Therefore, the area of the approximate parallelogram formed ≈ The area of the circle
The area of a parallelogram = The base × The height
∴ The area of the approximate parallelogram formed = 9.42 × 3 ≈ The area of the circle
The approximate area of the circle = 9.42 × 3 square inches.

The area of a triangle is 36 cm square. Give three possible sets of dimensions for the triangle and explain whether or not you can also give the triangles' side length.
Answers
Answer:
[tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]
[tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]
[tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]
Step-by-step explanation:
Given
Shape: Triangle
[tex]Area = 36cm^2[/tex]
Solving (a): Three possible dimensions
The area of a triangle is:
[tex]Area = 0.5 * Base * Height[/tex]
Let: [tex]Base = 6cm[/tex]
So, we have:
[tex]36= 0.5 * 6* Height[/tex]
[tex]36= 3* Height[/tex]
Solve for Height
[tex]12 = Height[/tex]
[tex]Height = 12[/tex]
So, a possible dimension is: [tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]
Let: [tex]Base = 4cm[/tex]
So, we have:
[tex]36= 0.5 * 4* Height[/tex]
[tex]36= 2* Height[/tex]
Solve for Height
[tex]18 = Height[/tex]
[tex]Height = 18[/tex]
So, a possible dimension is: [tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]
Let: [tex]Base = 9cm[/tex]
So, we have:
[tex]36= 0.5 * 9* Height[/tex]
[tex]36= 4.5* Height[/tex]
Solve for Height
[tex]8 = Height[/tex]
[tex]Height = 8[/tex]
So, a possible dimension is: [tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]
So, the three possible dimensions are:
[tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]
[tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]
[tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]
Solving (b): Can the side lengths be given
We can only determine the base and the height of the triangle, the third side length can not be determined using the available information

Find the probability of rolling a 5 or greater on the first die and a 2 or greater on the second die
Answers
Answer:
The probability is 1/9
Step-by-step explanation:
The probability of rolling a 5 the first time is 1/6
The probability of rolling a number greater than 2
Numbers greater than 2 are 3, 4, 5, 6
So the probability of rolling a number out of these four is 4/6
So the probability of rolling a five for the first time and the probability of rolling a number greater than 2 the second time will be
1/6 * 4/6 = 4/36 = 1/9
Answer:
1/3, 5/6, and 5/18.
Step-by-step explanation:
If a die has 6 sides, then because there are 2 sides equal or greater than 5 (5 and 6), then there is a 2/6 or 1/3 chance of rolling the first die. On the second roll, there are 4 sides equal or greater than 5 (2, 3, 4, 5, and 6), so there is a 5/6 chance of rolling it. To find the probability of both happening, multiply 1/3 by 5/6 to get 5/18.

A football quarterback goes for a two-point conversion when the ball is within 10 yards of the end zone. During the game, he has two opportunities for a two-point conversion. He misses the first attempt 50% of the time. When he misses the first attempt, he misses the second attempt 15% of the time. What is the probability of missing both two-point conversion attempts?
Answers
Answer:
P = 0.075 P = 7.5%
Step-by-step explanation:
We pretty much look for the probability that the player fails the first attempt and also fails the second attempt.
We know for a fact that the probability that the quarterback fails the first attempt is:
p(1) = 0.5
and we know that the probability that the quarterback fails the second attempt after failing the first is:
p(2/1) = 0.15
Then the probability of failure of both attempts is:
P(2/1) = p(1 and 2) / p(1)
p(1 and 2) = P(1) * P(1/2)
p(1 and 2) = 0.5 * 0.15
and that is
p(1 and 2) = 0.075
