Answer:
X= 40
Step-by-step explanation:
A triangle always equals 180°. In order to find x, add 75 and 65,
75 + 65 =140
then divide 140 and 180,
180 / 140 = 40
then in order to make sure it's the right answer add 75,65, and 40 together. If it equals to 180, then it's the right answer.

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)

Answer:
a=66m b=4.58cm
Step-by-step explanation:
a=5610 divided by 85=66 so 66m ×85 m =5610 meters squared
b=330cm ÷ 72 cm is 4.58. So 72×4.58=329.76 so rounded =330
= 5610 squared/2 -85
= 15,735,965m
(B) Step by step explanation;
Length= p/2 - width
= 330/2 - 72
Length= 93cm
The perimeter of a flag is 474 inches. The flag is 100 inches tall. How long is it?
Answers
If it is 100 inches tall, there are two sides that are the same length since flags are rectangles. 100 x 2 = 200. 474 - 200 = 274. 274 divided by two (we are dividing by two because there are two sides congruent on the flag) is 137.

Answer:
last option; h = 2t - d
Step-by-step explanation:
t = 1/2(d + h)
t = [tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex]
now multiply each side by 2 to eliminate denominator
2t = 2 ([tex]\frac{d}{2}[/tex] + [tex]\frac{h}{2}[/tex])

The speed of one car is 20% less than the speed of a second car. What per cent more time does the first car need to travel the same route as the second car?
Answers
Answer:
25% or more
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

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors
Answers
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
= 0.039

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)

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

[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

Use the equation 2m + 4s = 16 to complete the table, then graph the line using s as the
dependent variable.
Answers
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]
Simplifying the relation between m and s:[tex]2m + 4s = 16\\\\ \text{Dividing by 2 on both sides}\\\\ \dfrac{2m + 4s}{2} = \dfrac{16}{2}\\\\ m + 2s = 8[/tex]
How to evaluate the missing values?Use one of the given value and the equation to find the missing value:
For m = 0:[tex]m + 2s = 8\\ 0 + 2s = 8\\ 2s = 8\\\\ s = \dfrac{8}{2}\\\\ s = 4[/tex]
For s = 3:[tex]m + 2s = 8\\ m + 2 \times 3 = 8\\ m = 8 - 6\\ m = 2[/tex]
For m = -2:[tex]m + 2s = 8\\ -2 + 2s = 8\\ 2s = 10\\ \\ s = \dfrac{10}{2} \\\\ s= 5[/tex]
For s= 0:[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]

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.
