To divide a number by a 1-digit divisor, simply divide the number by the divisor. For example, 15 divided by 3 is 5, and 21 divided by 7 is 3. Practice makes perfect in this fundamental aspect of mathematics.

I understand you are trying to learn how to divide by 1-digit divisors. It is a fundamental topic in mathematics that you will use many times in the future.

Let's take the numbers 3 and 7 as examples. To divide by 3 or 7, simply take the number you are wanting to divide and divide it by either 3 or 7. For example, if we want to divide 15 by 3, you would simply perform 15 ÷ 3, which results in 5.

Now, if we want to divide 21 by 7, you would do 21 ÷ 7, which gives you a result of 3. It's that simple! Remember, the biggest key to success here is practice. The more you practice these divisions, the better you'll get at them.

Answer:

5000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms.

Explanation:

 The daily supply of oxygen for a particular multi cellular organism is provided by 625 square feet of lawn

Total area of lawn provided = 5,000 square feet

Number of organism for which provided lawn area supplies oxygen = Total area of lawn provided/ Daily requirement of lawn area for 1 organism.

Number of organism for which provided lawn area supplies oxygen = 5000/625 = 8 organisms.

So 5000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms.

A total of 5,000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms based on the ratio given.

The question can be solved using the concept of ratios. The ratio of lawn to organisms is 625 square feet to 1 multicellular organism. So, if we have 5,000 square feet lawn area, we can find how many organisms it can support by setting up a proportion and solving for the unknown number of organisms.

Let's denote the unknown number of organisms as X. The proportion would then be: 625/1 = 5000/X.

To solve this equation for X, we can cross-multiply and divide. So, X = 5000 / 625 = 8 multicellular organisms.

The product of -2 1/2 and -3 1/3 is 8 1/3. This is calculated by converting mixed numbers into improper fractions and then multiplying. Multiplying two negative numbers gives a positive result.

To compute the product of -2 1/2 and -3 1/3, first convert these mixed numbers into improper fractions.  -2 1/2 can be converted to -5/2 and -3 1/3 is -10/3.  Then, simply multiply these two fractions:

(-5/2) x (-10/3) = 50/6 = 25/3 or 8 1/3 .So the product of -2 1/2 and -3 1/3 is positive 8 1/3. Remember, multiplying two negative numbers results in a positive product.

The inverse function is [tex]\( f^{-1}(x) = \frac{x + 7}{4} \)[/tex].

To find the inverse function of [tex]\( f(x) = 4x - 7 \)[/tex], we follow these steps:

1. Replace [tex]\( f(x) \) with \( y \): \( y = 4x - 7 \)[/tex].

2. Swap[tex]\( x \) and \( y \): \( x = 4y - 7 \)[/tex].

3. Solve this equation for [tex]\( y \)[/tex].

So, let's solve for [tex]\( y \)[/tex]:

[tex]\[ x = 4y - 7 \][/tex]

Add 7 to both sides:

[tex]\[ x + 7 = 4y \][/tex]

Divide both sides by 4:

[tex]\[ \frac{x + 7}{4} = y \][/tex]

Thus, the inverse function of [tex]\( f(x) = 4x - 7 \)[/tex] is:

[tex]\[ f^{-1}(x) = \frac{x + 7}{4} \][/tex]

Step-by-step explanation:

There are two parallel lines given.

Two transversals cut them.

Here m and n are parallel.

Two transversals cut them so that a triangle is formed.

Let us use the property that sum of angles of a triangle = 180

Bottom angle of triangle = 39 (vertically opposite angles)

Top left angle = 4x+3 (vertically opposite angles)

Top right angle = 180-6x (linear pair property)

Now add these 3 and equate to 180

39+4x+3+180-6x = 180

2x = 42

Or x = 21

To order the numbers from least to greatest, we need to compare their values. Negative numbers are less than positive numbers, and among negative numbers, the one with the smaller absolute value is greater. We can convert the fractions to decimals to make it easier to compare all the numbers:

What is Algebraic expression ?

Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.

Let the three consecutive odd integers be x , x + 2 , x+ 4 then,

the sum of these three odd integers is 17 less than four times the smallest integer that is :

x + (x+2) + (x+4) = 4x -17

3x + 6 = 4x -17

4x - 3x  = 6 + 17

x = 23

x + 2 = 25

x +  4 = 27

Therefore, the three consecutive odd integers are 23, 25,27

Answer:

The number of melon was 3 and the number of apples was 45.

Step-by-step explanation:

1. Melons cost $20 per crate and apples cost $8 per create. If the total was 48 crates for $420, you can make the following system of equations, where [tex]x[/tex] is the number of melons and [tex]y[/tex] is the number of apples:

[tex]\left \{ {{x+y=48} \atop {20x+8y=420}} \right.[/tex]

2. By applying the Method of substitution, you can solve for [tex]y[/tex] in the first equation and substitute it into the second one to find [tex]x[/tex]. Then, you can substitute the value of [tex]x[/tex] into the first equation to find [tex]y[/tex]:

[tex]y=48-x[/tex]

[tex]20x+8(48-x)=420\\20x+384-8x=420\\12x=36\\x=3[/tex]

[tex]3+y=48\\y=45[/tex]

Final answer:

The order consisted of 3 crates of melons and 45 crates of apples.

Explanation:

To solve the problem of determining the number of crates of melons and apples based on the total cost and quantity, we can use a system of linear equations.

Given that melons cost $20 per crate and apples cost $8 per crate, with a total order of 48 crates for $420, we can set up the following equations:

Solving this system of equations:

Thus, the order consisted of 3 crates of melons and 45 crates of apples.

Let the width of rectangle= x centimeter

According to condition length =  (x+2) centimeter

As accoding to formula

perimeter of rectangle = 2( lenght +width)

so Perimeter = 2{(x+2) +(x)}     equation 1

Give perimeter = 60cm          equation 2

comparing  equation 1 and equation 2

2{(x+2) +(x)} = 60

Solving   2{2x+2} =60

The abs. minimum value of the given function was found to be 3.

Solution-

Here, the given function is,

[tex]f(x)=x^4-x^2-2x+5[/tex]

Then, calculating its first derivative,

[tex]{f}'(x)=4x^3-2x-2[/tex]

Then, calculating its second derivative,

[tex]{f}''(x)=12x^2-2[/tex]

Then, calculating all the critical values of the given function by equating the first derivative to 0,

[tex]\Rightarrow {f}'(x)=0[/tex]

[tex]\Rightarrow 4x^3-2x-2=0[/tex]

[tex]\Rightarrow 2x^3-x-1=0[/tex]

[tex]\Rightarrow 2x^3-x-1=0[/tex]

[tex]\Rightarrow 2x^3-2x+x-1=0[/tex]

[tex]\Rightarrow 2x(x^2-1)+(x-1)=0[/tex]

[tex]\Rightarrow 2x(x+1)(x-1)+(x-1)=0[/tex]

[tex]\Rightarrow (x-1)(2x(x+1)+1)=0[/tex]

[tex]\Rightarrow (x-1)(2x^2+2x+1)=0[/tex]

[tex]\Rightarrow (x-1)=0[/tex]    ( ∵ ignoring the imaginary roots)

[tex]\Rightarrow x=1[/tex]

Putting the value of x, in the second derivative,

[tex]{f}''(1)=12(1)^2-2=10[/tex]

As, the value of f"(x) is positive, the function attains its minimum value at x=1.

So, f(1) will give the absolute minimum value of the function,

[tex]f(1)=(1)^4-(1)^2-2(1)+5=3[/tex]

∴ The abs. minimum value of the given function is 3.
