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.

The difference between the largest 7-digit and the smallest 8-digit number is 1.

The aim is to find the largest 5-digit and the smallest 8-digit numbers, and then we need to determine the difference between these two values.

Let's start by finding the smallest 8-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, 1; therefore, it can be used in the highest place value.

Thus, we can create the required 8-digit smallest number with 0 and 1.

Hence, the smallest 8-digit number is 10000000.

Now, we will discover the largest 7-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 7-digit number with the digit 9.

Thus, the largest 7-digit number is 9999999.

Now, find the difference between these two values.

So, we can determine the difference between the smallest 8-digit number and the largest 7-digit number by subtracting the smallest from the largest.

Thus, we get,

⇒10000000 - 9999999

⇒1

Hence, 1 is the difference between the smallest 8-digit and the largest 7-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.

The ladder will now reach 21.7 ft.

Geometry is a branch of mathematics that deals with shapes, sizes, angles, and dimensions of objects.

Given is that a 45-foot ladder is placed against the side of a house so that it reaches 27 feet in height. Cooper grabs the ladder by its base and pulls it 4 feet farther away from the house.

Refer to the image attached. We can write in ΔCEB as -

EB² = 45² - 27²

EB² = (45 + 27)(45 - 27)

EB² = 72 X 18

EB² = 1296

EB = √1296

EB = 36 ft

Now -

AB = AE + EB = 36 + 4 = 40

From ΔDAB, we can write -

BD² = 45² - 40²

BD² = (45 + 40)(45 - 40)

BD² = 95 X 5

BD² = 475

BD = 21.7 ft

Therefore, the ladder will now reach 21.7 ft.

There was 1200 men and 800 women at the funfair in the morning

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:

When Richter scale magnitude is less 3. 0 to 3. 9, the frequency of occurrence in the whole world will be over 100,000 per year.

The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs (adjustments are included to compensate for the change in distance between different seismographs and the epicenter of the earthquake). The original formula is: [tex]Mₗ = log_{10}(A) - log_{10}(A₀ ) = log_{10}( \frac{A}{ A₀}) \\ [/tex]. The classification starts with "small" for magnitudes between 3.0 and 3.9, where earthquakes generally begin to be felt, and ends with "major" for magnitudes greater than 8.0, where significant damage is expected.

Answer:The steps in solving the quadratic function 7x – 9 = 7x^2 – 49x by completing the square are as follows:

Add and subtract (49/2)^2 = (36) to the right-hand side of the equation to complete the square. This gives us:

7x - 9 = 7x^2 - 49x + 36

Factor out the coefficient of the x^2 term, which is 7, on the right-hand side of the equation. This gives us:

7x - 9 = 7(x^2 - 7x + 6)

Take the square root of the number inside the parenthesis and add and subtract it, to get:

7x - 9 = 7(x - 3.5)^2 - 2.25

Now we can add 9 to both sides of the equation to get:

7x = 7(x - 3.5)^2 + 0.75

Now we can divide both sides by 7 to get:

x = (x - 3.5)^2 + 0.75/7

Now we can solve the equation by taking the square root of both sides and adding and subtracting 3.5 to get:

x = 3.5 ± √(x^2 - 7x + 6)

Now we have our solutions, x = 3.5 + √(x^2 - 7x + 6) and x = 3.5 - √(x^2 - 7x + 6) which are the solutions of the quadratic equation.

in other words, the hippo can eat 1 kg in 2 minutes.

now the answer to the question is easy :

how many minutes to eat 60 kg ?

remember, when we multiply one part of the fraction by a factor, we need to multiply the other post by the same factor to keep the overall value.

so, 60 kg = 60×1 kg

we multiply the numerator by 60, therefore, we need to multiply the denominator by 60 too. and we get
