i found out what 35% of 1020 is and then subtracted that by 1020.

Answer:

They are perpendicular!

Step-by-step explanation:

Get 7x-3y=-21 into y=mx+b format.

7x-3y=-21           Bring 7x to the other side

-3y=7x-21          Divide -3 by both sides, it cancels out on the y's side.

y=-7/3x+7       Two negatives equal a positive, that it why 7 is positive.

y=-7/3x+7 is the line, the other is y=-3/7x+5

The slope of this line is -7/3 , the slope of the given line is -3/7.

Lines are perpendicular if the slopes are opposite reciprocals, such as this.

So, while they intercept at different points on the y-axis, they will intersect at some point! This makes them perpendicular.

There are seven types of fractions.

We know that the fraction is used to represent the portion or part of the whole thing.

The fraction has two parts: numerator and denominator.

The top part of fraction is numerator and the bottom part is denominator.

consider a fraction 1/8.

Here, numerator is 1, denominator is 8

When certain thing is divided into 8 equal parts then each part of is represented by fraction1/8

The types of fractions are:

1) Proper fraction -  the numerator is always less than the denominator

2) Unit Fractions - the numerator of fraction is always 1

3) Improper fraction -  the numerator is greater than the denominator

4) Mixed fraction - it is a combination of a natural number and fraction

5) Like fractions - the fractions have the same denominators

6) Unlike fractions - the fractions have the different denominators

7) Equivalent fractions - the fractions have the same value when simplified.

For each 45-45-90 triangle, the period of the hypotenuse equals the length of the leg expanded via the square root of 2. That is the 45-45-90 Triangle Theorem.

A triangle is a polygon with three edges and 3 vertices. The terminology for categorizing triangles is greater than thousand years vintage, having been described at the very first web page of Euclid's elements.

In Euclidean geometry, any 3 elements, at the same time as non-collinear, determine a very precise triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean area). In special words, there's exceptional one plane that includes that triangle, and each triangle is contained in some plane.

Answer:

24 inches.

Step-by-step explanation:

In order for a triangle to be obtuse, one of its angles must be greater than 90 degrees. In a right triangle, the angle opposite the hypotenuse is always 90 degrees, so in order for the triangle to be obtuse, the hypotenuse must be the longest side.

To find the lowest whole number side length in inches that would ensure that the triangle is obtuse, we can use the Pythagorean theorem. The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

a^2 + b^2 < c^2

If we take the base 48cm and convert it to inches, 48cm = 48*0.393701 = 18.897638 inches

So the base is 18.897638 inches.

Now we have to find the lowest whole number side length of c so that:

18.897638^2 + b^2 < c^2

358.565744 + b^2 < c^2

We can see that the lowest whole number of c is 24 inches.

So, the lowest whole number side length in inches that would ensure that the triangle is obtuse is 24 inches.

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

Let x represent the number of men and y represent the number of women in the morning.

There are 400 more men than women at a funfair in the morning. Hence:

x = y + 400

x - y = 400     (1)

In the afternoon 2/5 of the men and 1/4 of the women left the funfair. hence:

number of men remaining = x - (2/5)x = (3/5)x

number of women remaining = y - (1/4)y = (3/4)y

There were 120 more men than women remaining at the funfair. therefore:

(3/5)x - (3/4)y = 120     (2)

The difference between the greatest 6-digit and smallest 6-digit numbers is 899999.

The aim is to find the smallest and largest 6-digit numbers, and then we need to find how many numbers are between these two values.

Let's start by finding the smallest 6-digit number.

We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit; that is, 1 and 1 can be used in the highest place value.

Thus, we can create the required 6-digit smallest number with 0 and 1.

Hence, the smallest 6-digit number is 100000.

Now, we will discover the largest 6-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 6-digit number with the digit 9.

Thus, the largest 6-digit number is 999999.

Next, we need to find the difference between these two values.

So, we can determine the difference between the smallest 6-digit number and the largest 6-digit number by subtracting the smallest from the largest.

Thus, we get,

⇒999999−100000

⇒899999

Hence, 899999 is the difference between the smallest 6-digit and the largest 6-digit numbers.

Answer:

One ft2 of sod costs $10.14 and one pot of ivy costs $0.24

Step-by-step explanation:

We can use the information provided to find the cost of one ft2 of sod and the cost of one pot of ivy.

To find the cost of one ft2 of sod, we can divide the total cost of sod by the total area of sod:

Cost of 1 ft2 of sod = (71 / 7) = $10.14/ft2

To find the cost of one pot of ivy, we can divide the total cost of ivy by the total number of pots:

Cost of 1 pot of ivy = (76 - 71) / (11 + 10) = $5 / 21 = $0.24/pot

So one ft2 of sod costs $10.14 and one pot of ivy costs $0.24

Keep in mind that these calculations only give approximate prices since it's not specified that the cost of ivy and sod is the same, but it's just an estimation based on the information that you provided.
