Answer:

[tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Key skills needed --> Division of fractions, Multiplication of fractions

1) 2/4 over 5/8 is the same thing as division ---> [tex]\frac{2}{4}[/tex] ÷ [tex]\frac{5}{8}[/tex] = [tex]\frac{2}{4}[/tex] × [tex]\frac{8}{5}[/tex] = [tex]\frac{16}{20}[/tex] = [tex]\frac{4}{5}[/tex]

2) Dividing by a fraction is the same thing as multiplying by its reciprocal.

Basically if you are dividing by [tex]\frac{3}{4}[/tex], you are multiplying by [tex]\frac{4}{3}[/tex]. A reciprocal is when the fraction's numerator becomes the denominator, and the fraction's denominator becomes the numerator. [tex]\frac{1}{2}[/tex] --> reciprocal is [tex]\frac{2}{1}[/tex] (or 2)

Answer:

y = 30200

x = -29950

Step-by-step explanation:

1.)

Let x represent children and y for adults.

200x + 450y = 7,600,000

x + y = 250

2.)

200x + 450y = 7,600,000

x + y = 250

-200(x + y = 250)

-200x + -200 = -50000

200x + 450y = 7,600,000

+ -200x + -200 = -50000

——————————————-

250y = 7550000

y = 30200

x + 30200 = 250

x = -29950

Uhm so I don’t know why for children I got a negative number? The wording for this question is very weird.

Step-by-step explanation:

Answer:

1 2/4 (1 1/2)

Step-by-step explanation:

keep, change, flip is how you solve these kinds of problems

the 3/4 stays the same

you turn the ÷ into x

and flip the 1/2 (2/1)

so it becomes

3/4x2/1= 1 2/4 (simplified is 1 1/2)

Answer:

S. 4

M. 2

S. 5

M. 8

And the graphing you just do those as m/s -->(M,S)

You can put the value of m or s in the given equation of m and s to obtained the missing value.

The completed table would look like:

[tex]\begin{array}{ccccc}m & 0 & 2 & -2 & 8\\s & 4 & 3 & 5 & 0\end{array}[/tex]

[tex]2m + 4s = 16\\\\ \text{Dividing by 2 on both sides}\\\\ \dfrac{2m + 4s}{2} = \dfrac{16}{2}\\\\ m + 2s = 8[/tex]

Use one of the given value and the equation to find the missing value:

[tex]m + 2s = 8\\ 0 + 2s = 8\\ 2s = 8\\\\ s = \dfrac{8}{2}\\\\ s = 4[/tex]

[tex]m + 2s = 8\\ m + 2 \times 3 = 8\\ m = 8 - 6\\ m = 2[/tex]

[tex]m + 2s = 8\\ -2 + 2s = 8\\ 2s = 10\\ \\ s = \dfrac{10}{2} \\\\ s= 5[/tex]

[tex]m + 2s = 8\\ m + 2 \times 0 = 8\\ m = 8[/tex]

Thus, the completed table would be:

[tex]\begin{array}{ccccc}m & 0 & 2 & -2 & 8\\s & 4 & 3 & 5 & 0\end{array}[/tex]

Step-by-step explanation:

t1 = d1/v1 , t2 = d2/v2.

d1 = d2 , and v1 = 0.8 v2

t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )

t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25

The value of the expression [tex]log_b(4b) = 3.[/tex]

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can use logarithmic rules to solve this problem.

First, we know that log_b(8) = 3.

Using the definition of logarithms, this means that b³ = 8.

Solving for b, we find that b = 2.

Next, we know that log_b(0.5) = -1.

Using the definition of logarithms, this means that b^(-1) = 0.5.

Solving for b, we find that b = 2.

Since both expressions have the same base, we can use the logarithmic rule that states log_b(xy) = log_b(x) + log_b(y) to simplify log_b(4b) as follows:

[tex]log_b(4b) = log_b(4) + log_b(b)[/tex]

We can use the logarithmic rule that states:

log_b(b) = 1 to simplify log_b(b):

[tex]log_b(4b) = log_b(4) + 1[/tex]

Now, we can use the logarithmic rule that states:

[tex]log_b(x) = log_c(x)/log_c(b)[/tex]

To convert log_b(4) to a base 2 logarithm:

[tex]log_b(4) = log_2(4)/log_2(b) = 2/1 = 2[/tex]

Substituting this into the expression we found earlier, we get:

[tex]log_b(4b) = log_b(4) + 1 = 2 + 1 = 3[/tex]

Therefore,

[tex]log_b(4b) = 3.[/tex]

Complete question :

In a class of 125 students, 27 are computer science majors, 51 are mechanical engineering majors, 12 are civil engineers and the rest are general engineering majors. Assume students only have one major.

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?

Answer:

0.039

Step-by-step explanation:

Total = T = 125

Computer Science = S = 27

Mechanical Engineering = M = 51

Civil Engineering = C = 12

General engineering, G = 125 - (27 + 51 + 12) = 35

Probability that none out of six chosen at random are Mechanical Engineering major :

Probability = required outcome / Total possible outcomes

Non mechanical engineering majors = 125 - 51 = 74

Probability none of 6 selected are mechanical engineering majors :

74C6 / 125C6

Recall :

nCr = n! / (n-r)! r!

, using calculator :

74C6 / 125C6 = 185250786 / 4690625500

= 0.0394938

Given

[tex]Line\ 1: (2, -3), (-4, -6)[/tex]

[tex]Line\ 2: (-3, 2), (2, -8)[/tex]

Required

Tell the relationship between both lines

We start by calculating the slopes (m) of both lines.

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For Line 1:

[tex]m_1 = \frac{-6 - (-3)}{-4 - 2}[/tex]

[tex]m_1 = \frac{-6 +3}{-4 - 2}[/tex]

[tex]m_1 = \frac{-3}{-6}[/tex]

[tex]m_1 = \frac{1}{2}[/tex]

For Line 2:

[tex]m_2 = \frac{-8 - 2}{2 - (-3)}[/tex]

[tex]m_2 = \frac{-8 - 2}{2 +3}[/tex]

[tex]m_2 = \frac{-10}{5}[/tex]

[tex]m_2 = -2[/tex]

The lines are not parallel because [tex]m_1 \ne m_2[/tex]

However, they are perpendicular, because:

[tex]m_1 = -\frac{1}{m_2}[/tex]

To prove this, substitute values for m1 and m2

[tex]\frac{1}{2} = -\frac{1}{-2}[/tex]

[tex]\frac{1}{2} = \frac{1}{2}[/tex] --- Proved

now multiply each side by 2 to eliminate denominator
