find the values of m &n .. please help !!
Answer:
m = 12.728 or 18/root (2)/2, n = 9
Step-by-step explanation:
To find m, we can use sin(45) and cos(45).
Since sin(45) = root (2)/2 and this equals 9/m.
We set the equation root (2)/2 = 9/m and solve for m.
9 divided by root (2)/2 would give us 18/root (2), or 12.728.
m is 12.728.
Same process for n but we are using cosine this time.
cos(45) = root (2)/2 and this equals n/12.728.
Solving for n would give us root (2)/2 times 12.728.
This gives us that n is 9.

which rule best described the following pattern 8,4,10,6,12,8,14
Answer:
-4 and +6
Step-by-step explanation:
The sequence follows a pattern of subtracting 4 then adding 6.
8 - 4 = 4 + 6 = 10 - 4 = 6 + 6 = 12 - 4 = 8 + 6 = 14

We are Given:_______________________________________________
ΔABC right angled at B
BC = 8
AC = 20
Part A:_____________________________________________________
Finding the length of AB
From the Pythagoras theorem, we know that:
AC² = BC² + AB²
replacing the given values
(20)² = (8)² + AB²
400 = 64 + AB²
AB² = 336 [subtracting 64 from both sides]
AB = 18.3 [taking the square root of both sides]
Part B:_____________________________________________________
Finding Sin(A)
we know that Sin(θ) = Opposite / Hypotenuse
The side opposite to ∠A is BC and The hypotenuse is AC
So, Sin(A) = BC / AC
Sin(A) = 8/20 [plugging the values]
Sin(A) = 2/5
Part C:_____________________________________________________
Finding Cos(A)
We know that Cos(θ) = Adjacent / Hypotenuse
The Side adjacent to ∠A is AB and the hypotenuse is AC
So, Cos(A) = AB / AC
Cos(A) = 18.3/20 [plugging the values]
Cos(A) = 183 / 200
Part D:_____________________________________________________
Finding Tan(A)
We know that Tan(θ) = Opposite / Adjacent
Since BC is opposite and AB is adjacent to ∠A
Tan(A) = BC / AB
Tan(A) = 8 / 18.3 [plugging the values]
Tan(A) = 80 / 183
Answer:
by using Pythagoras law
ac²=ab²+bc²
20²=ab²+8²
ab²=20²-8²
AB=√336=18.33
Step-by-step explanation:
sin a=p/h=8/20=2/5
cos a =b/h=18.33/20
tana =p/b=8/18.33
At the rodeo, 256 hot dogs were sold for a total of $768. If each hot dog sold for the same amount, what would be the cost of 24 hot dogs?
Answer:
$72
Step-by-step explanation:
$768/265 = $3
$3 x 24 = $72
Answer:
$72
Step-by-step explanation:
768/256 = how much each hot dog was sold for
768/256 = 3
Each hot dog was sold for $3.
24*3 = $72
Therefore, the cost of 24 hot dogs is $72.

The petting zoo at the park has 61 ducks and sheep, combined. The animals have a total of 150 legs. How many sheep are there
Answer:
7
Step-by-step explanation:
The number of sheep in the petting zoo will be 7.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the petting zoo at the park has 61 ducks and sheep, combined. The animals have a total of 150 legs.
The number of sheep will be calculated by forming the linear equation for the total number of legs,
61 x 2 + 4s = 150
4s = 150 - 122
4s = 28
s = 7
The number of sheep will be 7.

Which is the midpoint of the segment joining (12, 2) and (-5, – 7)?
Answer:
[tex]m(x, y)=(\frac{7}{2} , -\frac{5}{2} )[/tex]

Midpoint of line segment is calculated as
[tex]m(x, y)=(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )[/tex] -----------(1)

Answer:
8 is the length of JB
Step-by-step explanation:
Key skills needed: Equations, Congruence
1) We need to find out an equation to make based on the lengths that are given. ΔJMB is congruent to ΔKMB because of Side-Angle-Side:
JB is congruent to BKAngle MBK would be a right angle, since it is supplementary to the right angle JBM. Since both are right angles they are congruent. Both triangles have the side BM. Using the reflexive property, BM is congruent to itself, so there you go --> Side-Angle-Side2) Now since both triangles are congruent, we can make the equation that the length of JM is congruent to the length of MK, using the fact that: If triangles are congruent, then corresponding parts are congruent.
3) This means that 16x -24 = 4x
Subtract 16x from both sides : -24 = -12x
Divide by -12 on both sides and get x = 2
4) Substitute x into the length of JB (16x-24)
16(2)-24 = 32-24 = 8
5) Therefore, the length of JB is 8

Answer:
y = (1/3)x
Step-by-step explanation:
1) Use the slope formula: (y2-y1)/(x2-x1) and then substitute both points into the formula. That should give you (2-0)/(6-0) = 2/6 = 1/3.
1/3 would then be your slope
2) Since the y intercept is (0,0), the y-intercept isn't needed in the slope intercept equation
So that would give you y = (1/3)x
