highest common factor of 275 and 350?
Answer:
25
Step-by-step explanation:
Factors of,
275 = 1, 5, 11, 25, 55, 275
350 = 1, 2, 5, 10, 7, 14, 25, 35, 50, 70, 175, 350
Highest common factor of 275 and 350 is 25.
The HCF of 275 and 350 is given by the equation A = 25
What is HCF and LCM?The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF
Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers
Product of HCF x LCM = product of two numbers
Given data ,
Let the HCF of the two numbers be represented as A
Now , the equation will be
Let the first number be p = 275
The factors of 275 = 1 , 5 , 11 , 25 , 55 and 275
Let the second number be q = 350
The factors of 350 = 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175 and 350
So , the highest common factor of 275 and 350 is 25
Therefore , the value of A is 25
Hence , the HCF is 25

Bricks are stacked according to the pattern shown below.
Each row contains one more brick than the row above it.
Part A
Determine a quadratic function to model the total number of bricks in the stack,
f(x), given a number of rows, m.
Answer:
Part A
The Quadratic Function to model the total number of bricks the stack is f(x) = x²
Part B
The number of bricks we will have for 50 rows is 2500 bricks
Step-by-step explanation:
Part A
Let the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = a·x² + b·x + c
We have;
When x = 0, f(x) = 0, therefore, f(0) = a×0² + b×0 + c = 0 + 0 + c = 0
∴ c = 0
When x = 1, f(x) = 1, therefore, f(1) = a×1² + b×1 + 0 = 1
∴ a + b = 1...(1)
When x = 2, f(x) = 4, therefore, f(2) = a×2² + b×2 = 4
∴ 4·a + 2·b = 4...(2)
Multiply equation (1) by 2, and subtract it from equation (2) gives;
4·a + 2·b - 2×(a + b) = 4 - 2 × 1
2·a = 2
a = 1
From equation (1), we have;
b = 1 - a = 1 - 1 = 0
b = 0
∴ f(x) = a·x² + b·x + c = 1·x² + 0·x + 0 = x²
Therefore, the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = x²
Part B
If there are 50 rows in the stack, then we have, x = 50
Therefore;
f(50) = 50² = 2500
The number of bricks we will have for 50 rows is f(50) = 2500 bricks

you are hiking along a trail that in 13½ miles long.you plan to rest every 2¼miles.how many rest stops will you make?
Answer:
6 stops
Step-by-step explanation:
well if you stop every 2 1/4 miles for 13 1/2....13 1/2 divided by 2 1/4 is 6. So they'll stop 6 times.
The number of rest stops before finishing the trail is 5 rest stops.
Given,
You are hiking along a trail that is 13½ miles long.
you plan to rest every 2¼miles.
We need to find how many rest stops will you make.
How do distribute equally a given value?We divide the given value by the total number of items we want to distribute.
Example:
In 35 minutes how many 5 minutes?
= 35/5
= 7
We have,
Trail distance = 13 1/2 miles = 27/2 miles
Distance travelled before every each = 2 1/4 miles = 9/4 miles
The number of 4/9 miles in 27/2 miles.
= 27/2 / 9/4
= 27/2 x 4/9
= 27x4 / 2 x 9
= 3 x 2
= 6 times.
This means on the 6th time you have already finished the trail so,
You have rested 5 times before finishing the trail.
Thus the number of rest stops before finishing the trail is 5 rest stops.

Answer:
$106.08
Step-by-step explanation:
Given:
6x $5.00
5x $2.00
12x $1.00
9x= 0.50
6x25 cent

if manny the martian's shadow is 17.5 ft. in length and the shadow of a yard stick sitting perpendicular to the ground is 7.5 ft., what is manny's height
Answer:
Here the ratio of length of the shadow to the height of the object (in this case a yardstick) is 15:36. The ratio of shadow to the height of tree will also be the same. the shadow of tree is 25 feet long. So the height of tree will be (25*36)/15, that is 60 feet.

Which equations are parallel to the line -3x-6y=30? Select all that apply.
A. 2x-y=15
B. 4y=20-2x
C. x=18-2y
D. y=-3x+1
E. 5x+10y=10
F. 6-2y=4x
Answer:
B and E
Step-by-step explanation:
The slope has to be 1/2 because the equation in the question is equal to 1/2 so only B and E are parallel
The equations of the line parallel to -3x-6y=30 are 4y=20-2x and 5x+10y=10. The correct options are B and E.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line is y = mx + c. Given that the equations are parallel to the line -3x-6y=30.
To check the line parallel to -3x-6y=30 find the slope of each line and if the slope is equal to the given equation of the line then both the lines will be parallel to each other.
The slope of the given equation of the line:-
-3x-6y=30
y = ( -1 / 2 )x + 5
Slope = -1 / 2
Check all the equations:-
A. 2x-y=15 or y = -2x + 15
B. 4y=20-2x or y = ( -1 / 2 )x + 5
E. 5x+10y=10 or y = ( -1 / 2)x + 1
Therefore, equations 4y=20-2x and 5x+10y=10 are parallel to the line -3x-6y=30.

Nathaniel is building a rectangular shed. The length of the shed is 5 feet less than 3 times the width. The perimeter of the shed is 158 feet. What is the width of the shed?
Answer:
w = 21 feet
Step-by-step explanation:
The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Let's say the length of a rectangle is L while the width is W.
According to the given, L = 3W - 5
The perimeter of the rectangle is given as 2( length + width)..
Perimeter = 2(L + W)
2(3W - 5 + W) = 158
4W - 5 = 79
W = 21 feet.
Hence "The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet".

-1 is the gradient, if parallel then the gradient stays the same
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept
y = 4 - x , that is y = - x + 4 ← in slope- intercept form
with slope m = - 1
The slope crosses the y- axis at (0, 1 ) ⇒ c = 1
y = - x + 1 ← equation of parallel line
