c.5x=2/7
d.1/4x=5
e.1/5=2/3x
Answers
Answer:
a) x = 1/12
b) x = 3/4
c) x = 2/35
d) x = 20
e) x = 3/10
Step-by-step explanation:
a) 8x = 2/3
8x/8 = (2/3) / 8
x = 2/3 * 1/8
x = 2/24
x = 1/12
b) 1 1/2 = 2x
3/2 = 2x
(3/2) / 2 = 2x/2
3/2 * 1/2 = x
3/4 = x
x = 3/4
c) 5x = 2/7
5x/5 = (2/7) / 5
x = 2/7 * 1/5
x = 2/35
d) 1/4x = 5
1/4x * 4 = 5 * 4
x = 20
e) 1/5 = 2/3x
1/5 * 3/2 = 2/3x * 3/2
3/10 = x
x = 3/10

Identify the slope and y-intercept of each of the following lines. Then graph each line.
5x - 3y = 18
Do I put the answer on the attached graph?
Answers
Answer:
Yes, but you have to write what the slope and y-intercept of the equation is as well.
Step-by-step explanation:
(Not sure if you wanted the full answer or just if you should graph it but I'm putting it here anyways :^P)
First convert the equation from standard form to slope-intercept form.
5x-3y=18 -> 5x-18-3y -> 5/3x-6=y
5/3x is the slope and 6 is the y-intercept!
Then graph the equation.
First rewrite the equation in slope intercept form
slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]
[tex]\sf \rightarrow 5x - 3y = 18[/tex]
[tex]\sf \rightarrow - 3y = 18-5x[/tex]
[tex]\sf \rightarrow y = \dfrac{-5x+18}{-3}[/tex]
[tex]\sf \rightarrow y = \dfrac{-5x}{-3} + \dfrac{18}{-3}[/tex]
[tex]\sf \rightarrow y = \dfrac{5}{3}x -6[/tex]
comparing with y = mx + b, Here we can identify that the
slope: [tex]\sf \frac{5}{3}[/tex] and y-intercept: [tex]\sf -6[/tex]x-intercept: ( then y will be 0 )
[tex]\sf \hookrightarrow \dfrac{5}{3}x -6=0[/tex]
[tex]\sf \hookrightarrow \dfrac{5}{3}x=6[/tex]
[tex]\sf \hookrightarrow x=\dfrac{18}{5}[/tex]
[tex]\sf \hookrightarrow x = 3.6[/tex]
In order to graph the line
First put the x = 3.6 in the x axisSecondly put y = -6 in the y axisThen using a scale/ruler draw a straight line through this points.Graph:

Step-by-step explanation:
Begin by separating the division. Division in the argument of a logarithm function is equivalent to subtracting the log of the numerator and denominator:
[tex]ln( \frac{ {x}^{9} \sqrt{ {x}^{2} + 7} }{ {(x + 7)}^{7} } ) = ln( {x}^{9} \sqrt{ {x}^{2} + 7 } ) - ln(( {x + 7})^{7} )[/tex]
Multiplication under a logarithm means addition:
[tex] ln( {x}^{9}) + ln( \sqrt{ {x}^{2} + 7 }) - ln(( {x + 7})^{7} )[/tex]
Log rules say that exponents can be dragged to the front as coefficients:

Answer:

Step-by-step explanation:
To find the length of the given side with length "n", we must know the relationship between the different sections when the chords cross one another.
Now, the relationship we require is that when we multiply the 2 parts of both chords together, it will be equal to the product of the two sides in the other chord. Thus;
7(8) = 4(n)
56 = 4n

Given: ABCD is a trapezoid,
AD=10, BC=8,
CK- altitude of triangle ACD =30
Find: the area of ABCD
Answers
To find the area of the trapezoid we need to find the height of the trapezoid.
TrapezoidA trapezoid is a quadrilateral which is having a pair of opposite sides as parallel and the length of the parallel sides is not equal.
Area of TrapezoidThe area of a trapezoid is given as half of the product of the height(altitude) of the trapezoid and the sum of the length of the parallel sides.
\rm{ Area\ of\ trapezoid = \dfrac{1} {2}\times height \times (Sum\ of the\ parallel\ Sides)
The area of the trapezoid is 54 units².
Given to us :ABCD is a trapezoid
AD=10, BC = 8,
CK is the altitude altitude
Area of ∆ACD = 30
Area of ∆ACD,In ∆ACD,
\begin{gathered}\rm { Area\ \triangle ACD = \dfrac{1}{2}\times base\times height\\\\\ \end{gathered}
Substituting the values,
30 = 1/2 * AD × CK
30 = 1/2 * 10 × CK
(30 * 2)/10 = CK
CK = 6 units
Area of Trapezoid ABCD\rm{ Area\ of\ trapezoid = \dfrac{1} {2}\times height \times (Sum\ of\ the\ parallell Sides)
Area ABCD = [tex] \frac{1}{2} \times ck \times (ad + bc)[/tex]
Area ABCD = [tex] \frac{1}{2} \times 6 \times (10 + 8)[/tex]
Area ABCD = [tex] \frac{1}{2} \times 6 \times (18)[/tex]
Area ABCD = 54 units²
Hence, the area of the trapezoid is 54 units².

Step-by-step explanation: if 5/2:2/5 then 4/5 of a pint= 10/2 and you now only need 1/5 of a pint so you have to divid 5/2 by 2. that will give you 1.25 and 1.25 as a fraction is 5/4. now you need to change the fraction 10/2 so that you can add them. Equation for that is 10/2 times 2/2 that gives you 20/4 and 20/4+ 5/4=25/4 or 6 1/4(six and one fourth) of a cup
1. Let the sample space represent all the values from 1 to 10. Let A = {1, 2, 8} and B = {2, 7}. What is the P(A ∩ B)?
Answers
A [tex]\cap[/tex] B denotes to all common elements in both A and B
Sample space=S={1,2,3,4,5,6,7,8,9,10}So
A={1,2,8}B={2,7}2 is common
Hence
A $\cap$ B={2}
Answer:
P(A ∩ B) = 1/10
Step-by-step explanation:
Given:
Sample space (S) = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}A = {1, 2, 8}B = {2, 7}We can represent this information in a Venn diagram (see attachment 1).
As there are 10 equally likely outcomes (which must add up to 1), the probability of each outcome is 1/10.
Therefore, we can redraw the Venn diagram with the probabilities instead of the values (see attachment 2).
P(A ∩ B) means the probability of events A and B happening together, so it is the section of the diagram where events A and B overlap.
Therefore, P(A ∩ B) = 1/10
