Answer:
x = 1, x = 6
Step-by-step explanation:
Given equation:
[tex]\dfrac{x+2}{x-4}=\dfrac{2x}{x-3}[/tex]
Cross multiply:
[tex]\implies (x+2)(x-3)=2x(x-4)[/tex]
Expand brackets:
[tex]\implies x^2-3x+2x-6=2x^2-8x[/tex]
[tex]\implies x^2-x-6=2x^2-8x[/tex]
Collect and combine like terms:
[tex]\implies 2x^2-x^2-8x+x+6=0[/tex]
[tex]\implies x^2-7x+6=0[/tex]
Factor:
[tex]\implies (x-6)(x-1)=0[/tex]
Therefore,
[tex](x-6)=0\implies x=6[/tex]
[tex](x-1)=0 \implies x=1[/tex]
A laboratory technician needs to make a 40-liter batch of a 40% acid solution. How can the laboratory technician combine a batch of an acid solution that is pure acid with another that is 20% to get the desired
concentration?
The laboratory technician can combine L of the pure acid solution with L
of the 20% acid solution to get the desired concentration
Answer:
The technician can combine 10 liters of pure acid with 30 liters of 20% acid to get the desired concentration
Step-by-step explanation:
For pure acid, the concentration will be 100%
Let the liters of pure be a and the liters of 20% be b
Since we want 40 liters of total;
a + b = 40 ••••••••(i)
Also,
100% of a + 20% of b = 40% of 40
a + 0.2b = 16 •••••(ii)
From ii , a = 16-0.2b
Put this into i
16-0.2b + b = 40
0.8b = 40-16
0.8b = 24
b = 24/0.8
b = 30
Since a + b = 40
a = 40 - b
a = 40-30
a = 10

Kym plans to deposit $100 in an account at the end of each month for the next five years so that she can take a trip. (a) If Kym's opportunity cost rate is 6 percent compounded monthly, how much will she have in the account in five years? (b) How much will be in the account if the deposits are made at the beginning of each month?
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Monthly deposit= $100
Interest rate= 0.06/12= 0.005
Number of periods= 12*5= 60 months
a)
To calculate the future value, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
FV= {100*[(1.005^60) - 1]} / 0.005
FV= $6,977
b) If the deposit is at the beginning of the month, the interest is compounded one more period. We need to use the following formula:
FV= {A*[(1+i)^n-1]}/i + {[A*(1+i)^n]-A}
FV= 6,977 + {[100*(1.005^60)] - 100}
FV= 6,977 + 35
FV= $7,012

Step-by-step explanation:
It can be helpful to remember that an exponent signifies repeated multiplication. Here, the denominator factors cancel an equal number of numerator factors
[tex]\dfrac{10^6}{10^4}=\dfrac{10\cdot10\cdot10\cdot10\cdot10\cdot10}{10\cdot10\cdot10\cdot10}=10\cdot10=\boxed{10^2}[/tex]
At an arcade, there is a machine that accepts game tokens and returns tickets
that can be redeemed for prizes. Inserting 5 tokens returns 3 tickets and
inserting 10 tokens returns 8 tickets. You must insert tokens in multiples of 5 or
10, and you have a total of 20 tokens. Identify the domain in this situation?
*
Answer: 5, 10, 15, 20
Step-by-step explanation:
Domain is all possible values that can be used as inputs in a function.
The arcade machine accepts multiples of 5 game tokens. You have 20 tokens. As the machine accepts 5 game tokens, the minimum is 5. Since you have 20, the maximum is 20.
The multiples of 5 are:
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20

Two similar triangles have a pair of
corresponding sides of length 12 meters and 8
meters. The larger triangle has an area of 180
square meters. Find the area of the smaller triangle.
Answer:
The area of the smaller triangle is 80m²
Step-by-step explanation:
Find the scale factor to get the dimensions of the smaller triangle from the larger triangle using the given information:
[tex]\frac{\text{Large Triangle Length}}{\text{Small Triangle Length}}=\frac{12}{8}=\frac{3}{2}[/tex]
When scaling the area of similar shapes, we will square the scale factor for the lengths. We do this because area is a 2-dimensional measurement.
[tex](\frac{3}{2})^2=\frac{9}{4}[/tex]
Let x represent the area of the smaller triangle. So, we have:
[tex]\frac{9}{4}=\frac{180}{x}[/tex]
Cross multiply:
[tex]9x=4(180)[/tex]
[tex]9x=270[/tex]
Divide by 9:
[tex]x=\frac{720}{9}[/tex]
[tex]x=80[/tex]
Therefore, the area of the smaller triangle is [tex]80m^2[/tex].

Rotation is the transformation applied from brick A to brick B.
We need to find which transformation is applied from brick A to brick B.
What is transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, line, or geometric figure.
Rotation in mathematics is a concept originating in geometry. Any rotation is a motion of a certain space that preserves at least one point. It can describe, for example, the motion of a rigid body around a fixed point.
Brick A rotated 90° to brick B.
Therefore, rotation is the transformation applied from brick A to brick B.

Menal is making a plan to read her 625-page book. Her goal is to finish the book in 6 weeks. She is very busy during the first and fifth week, so she plans to read 50 pages during the first week and 45 pages during the fifth week. She will read the same number of pages during each of the remaining 4 weeks.
Answer:
p ≥ 132.5 pages
Step-by-step explanation:
Menal wants to know the minimum number of pages, p, she must read during each of those 4 weeks to meet her goal.What is the inequality for this problem?
Total pages = 625
First week = 50 pages
Fifths week = 45 pages
First week + fifth week
= 50 + 45
= 95 pages
Total pages remaining = Total pages - pages read
= 625 - 95
= 530 pages
Total pages remaining = 530 pages
Pages per week for 4 weeks ≥ 530 pages / 4 weeks
p ≥ 132.5 pages

The magnitude, m, of an earthquake is defined to be m = log startfraction i over s endfraction, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a "standard" earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth. 2 3 4.5 6.9
The magnitude, M, of an earthquake is 1.544 units when the magnitude of an earthquake is 1,000 times more intense than a standard earthquake
It is given that the magnitude of m, of an earthquake, is defined as:
[tex]\rm M=log\frac{I}{S}[/tex]
Where 'I' is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and 'S' is the intensity of a "standard" earthquake.
It is required to find the magnitude of the earthquake that is 1,000 times more intense than a standard earthquake.

Slope is -5
We then plug the slope in a set of points to find the y intercept

Often, there is more than one set of sequences that will take a preimage to an image. Determine one or two other sequences to create FGHIJ from ABCDE.
Hello.
The minimum number of rigid transformations required to show that polygon ABCDE is congruent to polygon FGHIJ is 2 (translation and rotation).
A rotation translation must be used to make the two polygons coincide.
A sequence of transformations of polygon ABCDE such that ABCDE does not coincide with polygon FGHIJ is a translation 2 units down and a 90° counterclockwise rotation about point D
Have a nice day
Answer:
FGHIJ: Dilate ABCDE with respect to the origin by a scale factor of 0.5, and then rotate the image 180° clockwise about point (0, 2). Translate the image 1 unit down and 7 units to the right.
FGHIJ: Reflect ABCDE across the x-axis, and then reflect the image across the y-axis (or vice versa). Dilate the image with respect to the origin by a scale factor of 0.5. Translate the image 3 units up and 7 units to the right.
