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.

(I really hope this helps!)

Answer:

25 - n

Step-by-step explanation:

n is a variable. It can represent any number. For example, 5 years ago, Mario would be 20 years old since 25-5 is 20.

So, if n is 8, you have to do 25 - 8 to find the answer to how old Mario was 8 years ago.

So his age n years ago, is 25 - n.

Hope this helps!

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

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

Answer:

y=-x+1

Step-by-step explanation:

y=-x+4

Substitute (0,1)

1=0+1

-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

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.

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:

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

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.

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.

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.

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".
