Answer: 2/3

Step-by-step explanation: In this problem, we have 8/15 ÷ 4/5. Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction.

8/15 ÷ 4/5 can be rewritten as 8/15 × 5/4

Now, we are simply multiplying fractions so we multiply across the numerators and multiply across the denominators.

8/15 × 5/4 = 40/60 = 2/3

Division the action of separating something into the parts. It is a basic mathematics operation. The number of pies made by the cooking club to sell  at a basketball game to raise money for the  new math books is 2.

The cafeteria  contributed three pies to the sale.

Each  pie was then cut into five pieces and sold.

There were a total of 40 pieces to sell.

Division the action of separating something into the parts. It is a basic mathematics operation.

Total 40 pieces are there to sell. Each  pie was cut into five pieces. Hence the total pie in 40 pieces were,

[tex]=\dfrac{40}{8}[/tex]

[tex]=5[/tex]

Thus total 5 pies was made.

Now as the cafeteria contributed three pies to the sale but we have total 5 pieces was made. For find out the number of pies made by the cooking club we have to subtract the total pies made to the pies contributed by the cafeteria.Thus the number of pies made by the cooking club,

[tex]=5-3[/tex]

[tex]=2[/tex]

Hence the number of pies made by the cooking club  to sell  at a basketball game to raise money for the  new math books is 2.

Answer:

C. 16

Step-by-step explanation:

basically the order of operations states you deal with parentheses first then indices then either division/multiplication and then addition/subtraction

So when you deal with 3- 1=2

the only operation left is multiplication(something in parenthesis stuck on another mathematical term without any other operation attached to it signals multiplication and it is commutative so it can be done in any pair. so u have 4×2×2=16

4x - 48 = x there is the equation

Answer:

x = 48/5

Step-by-step explanation:

Let x = number, then:

[tex]48 - 4x = x[/tex]

By adding 4x on each side:

[tex] 48 - 4x + 4x = x + 4x[/tex], which is [tex] 48 = 5x [/tex]

Then, divide by 5 on both sides:

The answer is 6.875 inches.

Step-by-step explanation:

After a snow storm, Michael measured [tex]6\frac{7}{8}[/tex] inches of snow.

We will convert this to improper fraction and then solve.

[tex]6\frac{7}{8}=\frac{55}{8}[/tex]

Now we can divide 55 by 8 to get decimal value.

This becomes 6.875 inches.

The speed of each planes are 375 mph and 415 mph.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,

Let x be the speed of the slower plane, in mph.

Then, the speed of the other plane is x +40 mph.

Hence, The distance between two planes decreases at the rate;

⇒ x + (x+40)

⇒ 2x + 40 mph.

So, we can write equation as;

⇒ 3950 / (2x+40) =  5

⇒ 3950 = 10x + 200

⇒ 10x = 3750

⇒ x = 375

Thus, The speed of the slower plane = x

                                                         = 375  mph.

And, The speed of the other plane = x +40

                                                      = 375 + 40

                                                      = 415 mph.

Final answer:

To solve the problem, we use the concept of relative speed and set up an equation with the combined distance traveled by both planes. Solving the equation reveals that the speed of the slower plane is 375 mph and the faster plane is 440 mph.

Explanation:

The problem of two planes flying toward each other with a speed difference and meeting after a certain amount of time is a typical algebra question in relative speed and motion. We can let the slower plane's speed be x mph and the faster plane's speed be x + 65 mph. Since they meet after 3 hours and are 2445 miles apart, the sum of their distances traveled will equal 2445 miles.

Using the equation d = rt, where d denotes distance, r the rate, and t the time, we set up two expressions for the distances each plane travels:

We then add these expressions and set the sum equal to the total distance:

3x + 3(x + 65) = 2445

Solving for x, we get:

6x + 195 = 2445

6x = 2445 - 195

6x = 2250

x = 375

Therefore, the speed of the slower plane is 375 mph and the speed of the faster plane is 375 + 65 = 440 mph.

This is a linear equation.

Did you really mean [tex]2t-t+4=0[/tex]? I just want to make sure since you said something about a quadratic in your question.

Step-by-step explanation:

[tex]2t-t+4=0[/tex] can be simplified to [tex]t+4=0[/tex].

This is a linear equation since the exponent on all the variables we have is 1.

To solve [tex]t+4=0[/tex] for t we are going to subtract 4 on both sides:

[tex]t+4-4=0-4[/tex]

From (1)

g = 27 - b ___(3)

Substitute (3) into (2)

27 - b - 3 = 3(b - 4)

24 - b = 3b - 12

Final answer:

The volume of the earth is approximately 1.0839 x 10¹⁵ cubic miles.

Explanation:

To find the volume of the earth, we can use the formula for the volume of a sphere: V = (4/3)πr³. Since we are given the diameter of the earth, we can calculate the radius by dividing the diameter by 2. In this case, the diameter is 7917.5 miles, so the radius is 3958.75 miles. Now, we can substitute the radius into the formula to find the volume:

V = (4/3)π(3958.75 miles)³

V ≈ 1.0839 x 10¹⁵ cubic miles.

Answer:

62.83 m²

Step-by-step explanation:

The area of the path is calculated as

area of outside circle - area of reservoir

= πr₁² - πr₂²

where r₁ is the radius of the outer circle and r₂ the radius of the reservoir

diameter of reservoir = 8 m, hence radius = 4 m

radius of outer circle = radius of reservoir + width of path = 4 + 2 = 6 m, thus

area of path = π × 6² - π × 4² = 36π - 16π = 20π ≈ 62.83 m²

Step-by-step explanation:

To obtain the product, each element in the expression [tex]\([8, -1, -5, 9]\)[/tex] is multiplied by -4, resulting in [tex]\([-32, 4, 20, -36]\).[/tex]

To find the product of -4 and the expression [tex]\([8, -1, -5, 9]\),[/tex] we multiply each element in the expression by -4.

This involves multiplying -4 by 8, -1, -5, and 9 individually.

The result of these multiplications is [tex]\([-32, 4, 20, -36]\).[/tex]

In other words, each element in the original expression is multiplied by -4 to obtain the corresponding element in the product.

This operation is a scalar multiplication, where a single number (in this case, -4) is multiplied by each element of a vector or array.

Scalar multiplication is a fundamental operation in linear algebra and is used to scale vectors or matrices by a constant factor.

In this context, multiplying the expression by -4 changes the magnitude of each element by a factor of 4 while preserving their relative positions within the array.

Answer:

The multiplication table does not have to end at factors of 9. You can multiply 3 and 8 by any factor to form an equivalent ratio.

Step-by-step explanation:

The ratio that is equivalent to 3/8 is 9/24.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

To determine an infinite number of ratios that are equivalent to 3/8, multiply by a ratio equivalent to 1

A ratio equivalent to 1 is a ratio such as 2/2 and 3/3.

This multiplication is equivalent to multiplying by 1.

So the ratio does not change.

One example is to multiply 3/8 by 2/2.

3/8 and 6/16 have the same ratio, 3:8.

Divide each numerator by each denominator.

⇒ 3÷8

⇒ 0.375

⇒ 6÷16

⇒ 0.375

It will also generate the same outcome if you divide each numerator by each denominator.

Hence, the ratio that is equivalent to 3/8 is 9/24.
