Triangle ABC is a scaled copy of triangle DEF. Side AB measures 12 cm and is the longest side of ABC. Side DE measures 8 cm and is the longest side of DEF.
a)Triangle ABC is a scaled copy of triangle DEF with what scale factor?
b)Triangle DEF is a scaled copy of triangle ABC with what scale factor?
Answers
Answer:
a) 3/2 or 1.5
b) 2/3 or ≈.66
Step-by-step explanation:
AB corresponds to DE because they are both the longest sides of their respective triangles.
a) The scale factor would be what you would multiply 8 by to get 12. 12/8 is 3/2 or 1.5
b) The scale factor would be what you multiply 12 by to get 8. 8/12 is 2/3 or ≈.66

In the figure below, m angle a=3x+5;m angle b=5x-18 , and m angle c=7x-2 .
Answers
Answer:
∠a=44,∠b=47, ∠c=89
Step-by-step explanation:
we can note that
∠a+∠b+∠c=180
hence,
3x+5+5x-18+7x-2=180
therefore,
3x+5x+7x+5-18-2=180
15x-15=180
15x=180+15
15x=195
x=[tex]\frac{195}{15}[/tex]
then, x=13.
with this values we can find all the angles:
∠a=3x+5 ⇒∠a=3(13)+5⇒∠a=39+5⇒∠a=44
∠b=5x-18⇒∠b=5(13)-18⇒∠b=65-18⇒∠b=47
∠c=7x-2⇒∠c=7(13)-2⇒91-2⇒∠c=89
We can corroborate these result by adding them.
∠a+∠b+∠c=
44+47+89=180

point y is between the points X and Z. if XY =3x- 4 , YZ = 2x +3, and XZ =24
Answers
Answer:
The numerical value of XY is 11
The numerical value of YZ is 13
Step-by-step explanation:
Given that
XY =3x- 4 , YZ = 2x +3, and XZ =24
As Y is between the points X and Z so the sum of length of XY and YZ will be equal to the length of XZ. Putting this in mathematical form
[tex]XY+YZ = XZ[/tex]
Putting the values
[tex](3x-4) + (2x+3) = 24\\3x-4+2x+3 = 24\\5x-1 = 24\\5x = 24+1 \\\frac{5x}{5} = \frac{25}{5}\\x = 5[/tex]
Now
[tex]XY = 3x-4 = 3(5)-4 = 15-4 = 11[/tex]
[tex]YZ = 2x+3 = 2(5)+3 = 10+3 = 13[/tex]
Hence,
The numerical value of XY is 11
The numerical value of YZ is 13

PBS News Hour reported in 2014 that 39.4% of Americans between the ages of 25 and 64 have at least a two-year college degree.† Assume that 55 Americans between the ages of 25 and 64 are selected randomly.
(a) What is the expected number of people with at least a two-year college-degree?
(b)What are the variance and standard deviation for the number of people with at least a two-year college degree? (Round your answers to four decimal places.)
Answers
Answer:
Mean = 22
Variance = 13.1320
Standard Deviation = 3.6238
Step-by-step explanation:
From the question, we can deduce that
n = 55 (sample)
p = 39.4% (proportion of those within the given range)
Solving (a): Expected Value, E(x)
This is calculated using the following formula.
E(x) = np
Substitute values for n and p
E(x) = 55 * 39.4%
E(x) = 55 * 0.394
E(x) = 21.67
E(x) = 22 ---- Approximated
Hence, the expected number of people is 22
Solving (b): Variance (σ²) and Standard Deviation (σ)
σ² is calculated as thus:
σ² = np(1 - p)
σ² = 55 * 39.4% * (1 - 39.4%)
σ² = 55 * 0.394 * (1 - 0.394)
σ² = 55 * 0.394 * 0.606
σ² = 13.13202
σ² = 13.1320 ---- Approximated
σ is calculated as follows:
σ = √σ²
Substitute value for σ²
σ = √13.13
σ = 3.6238 ----- Approximated

Answer:
The 2-yard pièce of cotton cloth for $13.26
Step-by-step explanation:
2 yards is 6 feet then it would be $2.21 per foot.
The 17 foot piece would cost $3.29 per foot.
To answer this question, you need to determine which one has a lower price per unit. In this scenario, you must divide the price of the cloths by their length in feet.
For the 2-yard piece of cotton cloth, first convert the length to feet. There are three feet in a yard, so the cloth is 6 feet. Then divide:
13.26/6=2.21
For the 17-foot piece of cotton cloth, simply divide:
55.93/17=3.29
The 2-yard piece of cotton cloth for $13.26 is the better buy because it has a lower unit price.
Hope this helps!!
