16) r = C/(2·π)
17) [tex]r^2 = \dfrac{3 \ \cdot V}{\pi \cdot h}[/tex]
18) x = (9 - 3·y)/2
19) Please find attached the required graph of the inequality x ≤ 4 created with MS Excel
20) z ≥ 1
Solve each inequality and graph the solution
21) n ≤ 1
22) p > -5
23) -3 ≤ q ≤ 2/5
24) x > 1/5
25) x < -11
26) 7
Step-by-step explanation:
Solving for the indicated variable
16) C = 2·π·r for r
Dividing both sides by 2·π gives;
C/(2·π) = 2·π·r/(2·π) = r
∴ r = C/(2·π)
17) [tex]V = \dfrac{1}{3} \cdot \pi \cdot r^2 \cdot h \ for \ r^2[/tex]
Dividing both sides by [tex]\left( \dfrac{1}{3} \cdot \pi \cdot h \right)[/tex] gives;
[tex]\dfrac{V}{\left( \dfrac{1}{3} \cdot \pi \cdot h \right)} = \dfrac{ \dfrac{1}{3} \cdot \pi \cdot r^2 \cdot h}{\left( \dfrac{1}{3} \cdot \pi \cdot h \right)}[/tex]
[tex]\therefore r^2 = \dfrac{V}{\left( \dfrac{1}{3} \cdot \pi \cdot h \right)} = \dfrac{3 \ \cdot V}{\pi \cdot h}[/tex]
[tex]r^2 = \dfrac{3 \ \cdot V}{\pi \cdot h}[/tex]
18) 2·x + 3·y = 9 for x, gives;

Answer:
1/6=6
Step-by-step explanation:
Conversion a mixed number 2 1/

to a improper fraction: 2 1/4 = 2 1/
4
= 2 · 4 + 1/
4
= 8 + 1/

To find new numerator:
a) Multiply the whole number 2 by the denominator 4. Whole number 2 equally 2 * 4/
4
= 8/
4
b) Add the answer from previous step 8 to the numerator 1. New numerator is 8 + 1 = 9
c) Write a previous answer (new numerator 9) over the denominator 4.
Two and one quarter is nine quarters
Divide: 9/

Find x round your answer to the nearest tenth of a degree
Answer:
x = 49.4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp /adj
tan x = 14/12
Taking the inverse tan of each side
tan ^-1 ( tan x) = tan ^-1 (14/12)
x =49.39870535
x = 49.4
Answer:
x = 49.4
Step-by-step explanation:
It's right triangle , so we can use trigonometry functions
tan θ = opposite side / adjacent side
tan x = 14 / 12
Taking inverse tan of each side
[tex] \small \sf \leadsto \: tan { }^{ - 1} (tan \: x \: ) = tan \: {}^{ - 1} ( \frac{14}{12}) \\ [/tex]
x = 49.39870535
Round nearest tenth of degree = 49.4

What is the value of X in the figure show
Answer:
x=11
Step-by-step explanation:
The equation for the problem is 4x-2=42. The angle (4x-2) is equal to 42 degrees because it is vertical to the angle with 42 degrees. If angles are vertical, they are equal to each other.
Add 2 to both sides of the equation.
4x+2=4x 42+2=44
Simplify.
4x=44
Divide 4 by both sides.
4x/4=x 44/4=11
Simplify to get the final answer.

Answer:
[tex]\boxed {\boxed {\sf d= \sqrt{34}}}[/tex]
Step-by-step explanation:
We want to find the distance between two points, so the following formula is used.
[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Where (x₁, y₁) and (x₂, y₂) are the points we are finding the distance between.
We are given the points (-2, -1) and (3,2). If we match the corresponding value and variable we see that:
x₁= -2 y₁= -1x₂= 3 y₂= 2Substitute the values into the formula.
[tex]d= \sqrt {(-2-3)^2+(2--1)^2[/tex]
Solve the parentheses.
-2 -3 = -5 2--1 = 2+ 1 = 3[tex]d= \sqrt{(-5)^2+(3)^2[/tex]
Solve the exponents.
(-5)²= -5*-5= 25 (3)²= 3*3=9[tex]d= \sqrt{25+9}[/tex]
Add.
[tex]d= \sqrt{34}[/tex]
This radical cannot be simplified, so the distance between the two points is √34 and choice 3 is correct.
what is the vertex form of the equation y equals 3x squared + 6x - 4
Answer:
y = 3(x + 1)² - 7
Step-by-step explanation:
y = 3x² + 6x - 4
First, factor out the coefficient of the quadratic eq'n:
y = 3(x² + 2x - ⁴/₃)
Use the "complete the square" rule;
The "x² + 2x" should be rewritten as "(x + 1)² - 1", i.e. place into squared brackets x (without the power 2) and add half the coefficient of the x-term, you then need to subtract the square of the constant term in the squared brackets and then simplify:
y = 3((x + 1)² - 1 - ⁴/₃)
y = 3((x + 1)² - ⁷/₃)
Finally, multiply the 2 terms you end up with by the 3, factored out initially:
y = 3(x + 1)² - 7

the sum of five consecutive numbers is 700, what is the first number?
Answer:
The first number is 138.
Step-by-step explanation:
Let the first number be x.
Then since they are consecutive numbers, the second number will be (x + 1), the third (x + 2), the fourth (x + 3) and the fifth being (x + 4).
We are given that their sum is 700. Therefore:
[tex]x+(x+1)+(x+2)+(x+3)+(x+4)=700[/tex]
Solve for x. Combine like terms:
[tex]5x+10=700[/tex]
Subtract 10 from both sides:
[tex]5x=690[/tex]
Divide both sides by five. Therefore:
[tex]x=138[/tex]
The first number is 138.
Answer:
138
Step-by-step explanation:
(n) + (n+1) + (n+2) + (n+3) + (n+4) = 700
5n + 10 = 700
5n = 690
n = 138

Answer: Unlock code = 76
==========================================================
Explanation:
Use a factor tree to find the prime factorization of each value
22 = 2*11
30 = 2*3*5
Both values have '2' in common and this is the largest such value. Therefore, the GCF of 22 and 30 is 2.
So E = 2
----------------------------
Since 3 and 8 have no factors in common (other than 1), this means the LCM is 3*8 = 24
We can say that F = 24.
If the numbers had some larger number in common, then we'd have to do a bit more work to find the LCM.
----------------------------
As the hint suggests, we'll use the distributive property to show that
3*(7+10) = G + 30
3*7 + 3*10 = G + 30
21 + 30 = G + 30
21 = G .... subtract 30 from both sides; they cancel and go away
G = 21
----------------------------
Use the same idea for the other equation as well
5*(3 + H) = 15 + 45
5*3 + 5*H = 15 + 45
15 + 5H = 45
5H = 45 ............ subtract 15 from both sides; they go away
H = 45/5 ......... divide both sides by 5
H = 9
------------------------------
The unlock code is
E+F+G+H = 2+24+21+29 = 76

A ramp is used so a trolley can be wheeled on to a platform.
The cross-section of the ramp is drawn as a right-angled triangle with
the unknown height labelled as x.
1 Is the unknown length in this triangle (shown as x) the length of
the hypotenuse? Explain ur answer.
Answer:
The hypotenuse is sqrt ( 2x^2)
Step-by-step explanation:
Given a right angled triangle, we can find the hypotenuse of a triangle using the Pythagorean theorem which says that c^2 = a^2 + b^2, where a is the length, b is the perpendicular height and c is the hypotenuse. The length of the triangle (l) is x and the height of the triangle is also x. By substituting the values,
c^2 = x^2 + x^2 = 2x^ 2
There are two possible answers to c but the hypotenuse cannot be negative.
Hence,
c = Sqrt (2x^2)

A six sided die has the colors: red, green, green, blue, pink and yellow. The die is rolled twice. What is the probability of two rolls with at least one red outcome?
Answer:
1/6
Step-by-step explanation:
The six sided die has a total of 6 possible outcomes with red being only one of them. Therefore, this means that in a single dice roll the probability of it being red would be 1/6. Since, the question asks the probability of at least one red outcome, the second roll can be anything. Therefore, the probability of the second roll would be 6/6 or 1 and if we multiply this by the probability of the first roll it would stay the same. Meaning that the probability of getting atleast one red outcome in two rolls would be 1/6

If f(x) = −4x 2 + 15, then f(−3)
Answer:
-21
Step-by-step explanation:
f(-3) = -4(-3)² + 15 = -4(9) + 15 = -36 + 15 = -21
Answer:
f(-3) = -21
Step-by-step explanation:
f(x) = −4x²+ 15
f(-3) = -4(-3)² + 15
f(-3) = -4(9) + 15
f(-3) = -36 + 15
f(-3) = -21
The inverse of the function f(x) = one-half x plus 10 is shown. h(x) = 2x- What is the missing value? 1 5 10 20
Answer:
20
h(x) = 2x - 20
Step-by-step explanation:
f(x) = ¹/₂ x + 10
First, isolate x, like so:
f(x) - 10 = ¹/₂ x
x = 2(f(x) - 10)
x = 2f(x) - 20
Now, simply switch f(x) with x and x with h(x), like so:
h(x) = 2x - 20
