Find the HCF of 30 and 45.
Answer:
15
Step-by-step explanation:
Since 30 and 45 are relatively small numbers, it's not a big deal to list every single one of their common factors.
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 45: 1, 3, 5, 9, 15, 45
Now that we have a list, it's easy to see which number is the highest common factor, which is, of course, 15.
Answer:
HCF of 30 and 45 is 15.
Step-by-step explanation:
Factors of 30 : 1, 2, 3, 5, 6, 10, 15, 30.
Factors of 45 : 1, 3, 5, 9, 15, 45.
Common Factors : 1, 3, 5, 15
Highest Common Factor : 15

the bearing of a plane from the airport is 65.
Calculate the bearing of the airport from the plane
Answer:
The bearing of the airport from the plane is 245°
Step-by-step explanation:
The bearing of a point from a location is given by the angle in degrees of rotation from the Northern direction of the location to the direction of the location of the point
The given bearing of the plane from the airport = 65°
Therefore, the direction of the plane from the Northern direction of the airport = 65°
From the Northern direction of the plane, the bearing of the airport = 245°

x+2y=17
8x+3y=45
answer fast
Answer fast? What?
x + 2y = 17...Equation A
8x + 3y = 45...Equation B
Solve A for x.
x = 17 - 2y
Plug this into B to solve for y.
8(17 - 2y) + 3y = 45
136 - 16y + 3y = 45
136 - 13y = 45
-13y = 45 - 136
-13y = -91
y = -91/-13
y = 91/13
y = 7
To find y, plug x = 7 into either equation to find x.
I will use Equation A.
x + 2y = 17
x + 2(7) = 17
x + 14 = 17
x = 17 - 14
x = 3
Answer: x = 3, y = 7
The solution to the system of equations is (x = 3) and (y = 7).
To find the values of x and y that satisfy the given system of equations:
1. (x + 2y = 17)
2. (8x + 3y = 45)
We can use either the substitution method or the elimination method. Let's use the elimination method to solve this system
Step 1: Multiply both sides of the first equation by 3 to make the coefficients of y in both equations the same:
(3x + 6y = 51)
Step 2: Now, subtract the modified first equation (3x + 6y = 51) from the second equation (8x + 3y = 45):
(8x + 3y) - (3x + 6y) = 45 - 51)
Simplify:
(8x + 3y - 3x - 6y = -6)
Step 3: Combine like terms:
(5x - 3y = -6)
Step 4: Now, we have two equations:
1. (x + 2y = 17)
2. (5x - 3y = -6)
Step 5: Now, you can either use the substitution method or the elimination method again to find the values of x and y. Let's use the elimination method again to eliminate y: Multiply the first equation by 3 and the second equation by 2 to make the coefficients of y the same:
1. (3(x + 2y) = 3 times 17) => (3x + 6y = 51)
2. (2(5x - 3y) = 2 times -6) => (10x - 6y = -12)
Step 6: Now, add the modified first equation (3x + 6y = 51) to the modified second equation (10x - 6y = -12): (3x + 6y + 10x - 6y = 51 - 12)
Simplify: (13x = 39)
Step 7: Divide both sides by 13 to solve for x:
(x = frac{39}{13})
(x = 3)
Step 8: Now that we have the value of x, we can find the value of y by substituting it back into either of the original equations. Let's use the first equation:
(x + 2y = 17)
(3 + 2y = 17)
Step 9: Solve for y:
(2y = 17 - 3)
(2y = 14)
(y = frac {14}{2})
(y = 7)

Number 5) Whoever has the right answer ill give brainliest
Given triangle PRS is congruent to triangle CFH, find the values of x, y, and z.
Answer:
x = 23
y = 7
z = 11
Step-by-step explanation:
Since ∆PRS ≅ ∆CFH, therefore,
m<R = m<F
13y - 1 = 90° (substitution)
Add 1 to both sides
13y - 1 + 1 = 90 + 1
13y = 91
Divide both sides by 13
13y/13 = 91/13
y = 7
Since ∆PRS ≅ ∆CFH, therefore,
PS = CH
2x - 7 = 39 (substitution)
Add 7 to both sides
2x - 7 + 7 = 39 + 7
2x = 46
Divide both sides by 2
2x/2 = 46/2
x = 23
Since ∆PRS ≅ ∆CFH, therefore,
m<S = m<H
Find m<S
m<S = 180 - (m<P + m<R) (sum of ∆)
m<S = 180 - (28 + (13y - 1)) (substitution)
Plug in the value of y
m<S = 180 - (28 + (13)(7) - 1))
m<S = 180 - (28 + 91 - 1)
m<S = 180 - 118
m<S = 62°
Therefore, since m<S = m<H,
62° = 6z - 4 (substitution)
Add 4 to both sides
62 + 4 = 6z - 4 + 4
66 = 6z
Divide both sides by 6
66/6 = 6z/6
11 = z
The values of x, y, and z are;
x = 23
x = 23y = 7
x = 23y = 7z = 11
We are told that triangle PRS is congruent to triangle CFH.
Since both triangles are congruent, by inspection we can see that;
m<R = m<F
m<F is a right angle = 90°. Thus;
13y - 1 = 90
13y = 90 + 1
13y = 91
y = 91/13
y = 7
Also by inspection;
PS = CH
2x - 7 = 39
2x = 39 + 7
2x = 46
x = 46/2
x = 23
Since m<R is 90°, then;
m<S = 180 - (90 + 28)
m<S = 62°
By inspection;
m<S = m<H
Thus;
6z - 4 = 62
6z = 66
z = 66/6
z = 11
