The value of the fraction 3/4 of 56 is 42.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

On the other hand, a fraction appears in the numerator or the denominator of a complex fraction.

The value of the fraction will be:

= 3/4 × 56

= 3 × 14

= 42

The value is 42.

Answer: I believe it would be 55 but It would help if it says what kind of triangle it is.

Step-by-step explanation:

Answer:

The answer is 91°

Step-by-step explanation:

In any triangle, the sum of all angles is equal to 180°

So,

35° + 54° + x = 180°

x = 180 - 89

x = 91°

Thus, The third angle is 91°

3(x-4)+5=2(x-3)+4

3x-12+5=2x-6+4

3x-7=2x-2

x-7=-2

Answer:

We can use the point-slope formula to find the equation of the tangent line. The point-slope formula is given by:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line, and m is the slope of the line. To find the equation of the tangent line, we need to find the slope of the line and a point on the line.

To find the slope of the line, we can use the definition of derivative. The derivative of a function f(x) at a point x0 is defined as:

f'(x0) = lim(h->0) (f(x0 + h) - f(x0))/h

In our case, the function f(x) is given by f(x) = x^2 - 5, and the point x0 is -2, so we have:

f'(-2) = lim(h->0) (f(-2 + h) - f(-2))/h

Substituting the value of the function f(x) = x^2 - 5, we get:

f'(-2) = lim(h->0) (((-2 + h)^2 - 5) - ((-2)^2 - 5))/h

Simplifying the expression, we get:

f'(-2) = lim(h->0) (h^2 - 4h)/h

Since the limit is defined as h approaches 0, we can drop the h from the denominator since it will become insignificant in the limit:

f'(-2) = lim(h->0) (h^2 - 4h)

Now we can evaluate the limit as h approaches 0:

f'(-2) = lim(h->0) h^2 - 4h

In the limit, h^2 becomes 0, so we are left with:

f'(-2) = lim(h->0) - 4h

Since the limit is defined as h approaches 0, the value of the limit is simply -4 times 0, which is 0. Therefore, the slope of the tangent line is 0.

Now that we know the slope of the tangent line, we need to find a point on the line. We are told that the line passes through the point (-2, f(-2)) on the function f(x) = x^2 - 5. Substituting the value of the function, we get:

(-2, f(-2)) = (-2, (-2)^2 - 5) = (-2, -9)

So the point on the line is (-2, -9).

We now have the slope and a point on the line, so we can use the point-slope formula to find the equation of the line. Substituting the values into the point-slope formula, we get:

y - (-9) = 0(x - (-2))

Simplifying, we get:

y = -9

Therefore, the equation of the tangent line that passes through the point (-2, -9) with a slope of 0 is given by y = -9.

The vertex and range of y = |x + 1| + 3 will be (−1, 3); 3 ≤ y < ∞ respectively.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

You may get the vertex of y = |x + 1| + 3 as follows.

Where the absolute values are zeros are the vertex points of the absolute value function.

|x + 1| = 0

x + 1 = 0

x = -1

Substitute the value into an original function,

y = |-1 + 1| + 3

y= 0 + 3

y = 3

As a result, the vertex is at (-1, 3)

Remember that the domain is specified in the range of (-∞, ∞) while determining the range.

Given that |x + 1| ≥ 0 , (absolute value is always 0 or positive)

The result of adding 3 to the inequality's two sides is

|x + 1| + 3 ≥ 3

But since |x+1| + 3 is identical to f(x) = y, we have y = f(x) 3, which means that the range is specified for all values larger than 3.

So the range is 3 ≤ y < ∞

Thus,the vertex and range of y = |x + 1| + 3 will be (−1, 3); 3 ≤ y < ∞ respectively.

40 percent of Marley's attempts were strikes, when  Marley rolled 28 strikes out of 70 attempts.

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage. A % is a number that indicates how many out of 100 it is, and it can also be expressed as a decimal or a fraction. Put the percentage value in the numerator and 100 in the denominator to convert a percentage to a fraction.

Given,

28 strikes rolled by Marley

Total attempts = 70

For percentage,

28/ 70 × 100%

0.4 × 100%

40%

40 percent of Marley's attempts were strikes, when Marley rolled 28 strikes out of 70 attempts.

The time the Road Runner been running is 7.3 minutes

From the question, we have the following parameters that can be used in our computation:

Roadrunner speed = 72mph

Time for repair = 15 minutes

Speed = 220mph

Represent the time the Road Runner been running with x

The speed is calculated using

Speed = Distance/Time

So, we have the following representations

Roadrunner speed = Distance/Time

Wile Coyote speed = Distance/Time

This gives

72 = Distance/(15 + x) -- for the roadrunner

220 = Distance/x for the Wile Coyote

So, we have

Distance = 72(15 + x)

Distance = 220x

Substitute the known values in the above equation, so, we have the following representation

220x = 72(15 + x)

Open the brackets

220x = 1080 + 72x

Evaluate the like terms

148x = 1080

So, we have

x = 7.3

The solution to the equation is x = -28/9.To solve the equation 2 1/7 + 3/7(3x - 5) = -4, let's break it down step by step.

Step 1: Convert the mixed number 2 1/7 to an improper fraction. Multiply the whole number (2) by the denominator (7), then add the numerator (1). This gives us (2 * 7 + 1) / 7 = 15/7.

Step 2: Distribute the 3/7 to the terms inside the parentheses. Multiply 3/7 by each term, which gives us (3/7) * 3x = 9x/7 and (3/7) * (-5) = -15/7.

Step 3: Substitute the converted mixed number and the distributed terms back into the equation. The equation becomes 15/7 + 9x/7 - 15/7 = -4.

Step 4: Combine like terms. Add the fractions with the same denominator: (15/7 - 15/7) + 9x/7 = -4. The fractions cancel each other out, leaving us with 9x/7 = -4.

Step 5: Isolate the variable. Multiply both sides of the equation by the reciprocal of 9/7, which is 7/9. This gives us (7/9)(9x/7) = (7/9)(-4). The 7/9 on the left side cancels out, leaving x = (-28/9).

Step-by-step explanation:

Answer:

each girl scored 1 point and each boy scored 20 points.

Step-by-step explanation:

Let $g$ be the number of points scored by each girl and $b$ be the number of points scored by each boy. We can set up the following system of equations:

$$3g + 2b = 43$$

$$3g - 2b = 11$$

We can solve this system of equations using substitution. From the first equation, we have that $3g = 43 - 2b$. Substituting this expression for $3g$ into the second equation gives:

$$3(43 - 2b) - 2b = 11$$

Solving for $b$, we get:

$$129 - 6b = 11$$

$$6b = 118$$

$$b = 19.5$$

Since $b$ must be a positive integer, the only possible value for $b$ is $20$. Substituting this value into the first equation, we get:

$$3g + 2(20) = 43$$

Solving for $g$, we get:

$$3g = 3$$

$$g = 1$$

Therefore, each girl scored $1$ point and each boy scored $20$ points.
