Answer:
3/2
Step-by-step explanation:
Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7

What is the equation of the line that passes through (4, -1) and (-2, 3)?
Answers
Answer:
y= - 4/6x+1.66
Step-by-step explanation:
To get the slope you subtract y2-y1 / x2-x1. This gives the slope. Then you need to get the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
what is the slope of (19,14) & (21,19)
Answers
Step-by-step explanation:
Hey there!
Given; The points are; (19,14) and (21,19).
Note: Use slope formula.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{19 - 14}{21 - 19} [/tex]
Simplify it.
[tex]m = \frac{5}{2} [/tex]
Therefore, slope(m)= 5/2.
Hope it helps...
Answer:
slope = 5/2
Step-by-step explanation:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]\frac{19-(14)}{21-(19)}[/tex]
m=[tex]\frac{5}{2}[/tex]

Car Y travels 105 miles on 3 gallons of petrol. Car Z travels 80 miles on 9 litres of petrol.
Which car has better petrol consumption ( more miles per gallon)?
You may use the fact that 1 gallon =4.5 litres
Options are
A. None
B. Y
C. Z
Answers
Answer:
Car Z has better petrol consumption. Choice C. Z
Step-by-step explanation:
Petrol Consumption
Car Y travels 105 miles on 3 gallons of petrol. The average consumption is 105 / 3 = 35 miles/gallon
Car Z travels 80 miles on 9 litres of petrol. Since 1 gallon=4.5 litres, the consumption of car Z is 9/4.5= 2 gallons. The average consumption is 80/2 = 40 miles/gallon.
This means that car Z has better petrol consumption. Choice C. Z

Read the problem to choose the correct method, then solve. A farmer buys a tractor for $50,000. If the tractor depreciates 10% per year, use an exponential function to find the value of the tractor in 7 years. AD CO Exponential Growth, $97,435.86 Exponential Decay, $23,914.85 Exponential Growth, $315,000 Exponential Decay, 21,523.36
Answers
Answer:
The correct option is, Exponential Decay, $23,914.85.
Step-by-step explanation:
A farmer buys a tractor for $50,000.
It is provided that the the tractor depreciates 10% per year.
The exponential function for decay is:
[tex]y=a\cdot (1-r\%)^{t}[/tex]
Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:
[tex]y=a\cdot (1-r\%)^{t}[/tex]
[tex]=50000\times (1-0.10)^{7}\\\\=50000\times 0.4782969\\\\=23914.845\\\\\approx 23914.85[/tex]
Thus, the correct option is, Exponential Decay, $23,914.85.

one angle of an isosceles triangle measure 140 degrees. which other angles could be in that isosceles triangle?
Answers
Answer:
20!
Step-by-step explanation:
Isosceles triangles have 2 angles are the same. Since we can't do 140, because interior angles of a triangle equal 180, then we need to subtract 140 from 180. 180-140=40. 40/2 because of 2 angles=20. 20 is the angle.

2.Factor: 125x^6-27y^15
3.Multiply: (4x-7)(5x-8)
Answers
Answer:
1. 4(x² + 7x - 9)2. (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3. 20x² - 67x + 56Step-by-step explanation:
1. factor 4x^2+28x-36
= 4x² + 28x - 36
re-write 36=4*9, and 28=4*7
= 4x² + 4 * 7x - 4 * 9
factor out common term:
= 4(x² + 7x - 9)2. factor 125x^6-27y^15
= 125x⁶ - 27y¹⁵
=(5x²)³ - (3y⁵)₃
apply difference of cubes: x³-y³ = (x-y)(x²+xy+y²)
= (5x² - 36y⁵)(5²x⁴ + 5 * 3x²y⁵ + 3²y¹⁰)
refine:
= (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3. multiply (4x-7)(5x-8)
apply the FOIL method
= 4x * 5x + 4x (-8) + (-7) * 5x + (-7) (-8)
