Find all values of x that make the triangles congruent. Explain your reasoning.
Answer:
The values of x that make the triangles congruent.
x = 6 and x = 3
Step-by-step explanation:
Given
AC = 5x-2DC = 3x+10AB = 5xDB = 4x+3Given that the triangles are congruent.
According to the SAS (Side-Side-Side)
AC = DC
AB = DB
so
AC = DC
substituting AC = 5x-2 and DC = 3x+10
5x-2 = 3x+10
5x-3x = 10+2
2x = 12
divide both sides by 2
2x/2 = 12/2
x = 6
and
AB = DB
substituting AB = 5x and DB = 4x+3
5x = 4x+3
5x-4x = 3
x = 3
Therefore, the values of x that make the triangles congruent.
x = 6 and x = 3
VSpeeding A trucker handed in a ticket at a toll booth showing that in 2 h she had covered 159 mi on a toll road with speed limit 65 mph. The trucker was cited for speeding. Why
Answer:
The trucker was cited for speeding because his speed was above that of the speed limit of the toll road by 14.5mph
Step-by-step explanation:
Step 1
We calculate the speed of the trucker
Speed = Distance(miles)/Time(hours)
Distance = 159 miles
Time = 2 hours
Speed = 159 miles/2 hours
Speed = 79.5 miles per hour = 79.5 mph
From the question, we are told that: that toll road has a speed limit of 65mph
Step 2
We calculate the difference
= 79.5 mph - 65 mph
= 14.5 mph
Hence, the trucker was cited for speeding because his speed was above that of the speed limit of the toll road by 14.5mph

Which equation represents a line that is parallel to y = negative 2 x minus 5?
Answer:
Step-by-step explanation:
The equation of a line is y=mx+b
We currently have y=-2x-5, where the slope is -2
A parrallel line would have the same slope, so also -2
Any equation that has a slope, or m of -2 would be parallel!

Write an equation of the line that passes through (3,2) and is perpendicular to the line y= 1/3x-3
Answer:
y = - 3x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (3, 2) into the partial equation
2 = - 9 + c ⇒ c = 2 + 9 = 11
y = - 3x + 11 ← equation of perpendicular line
The sales tax on clothing that cost $24 is $1.68. How much would sales tax be on clothing that cost $96?
Answer:
$6.72
Step-by-step explanation:
1.68 is 7% of 24, so there is a 7% tax.
96x.07= 6.72
Answer: The sales tax would be 6.72
Step-by-step explanation: 24 is 1/4 of 96 so that means that you have to multiply the sales tax number by 4 and 1.68 x 4 = 6.72
Which linear equation can be used to represent a line perpendicular to Line W passing through point (-3,-2)?
line on graph is x=8 Help please
Answer:
D) y = -2
The equation of the perpendicular line to the given line is y = -2
Step-by-step explanation:
Explanation:-
Given point (-3,-2)
In graph the equation of line x = 8 ( parallel to y- axis )
1 x + o y - 8 =0
The equation of the perpendicular line to the given line
b x - a y + k =0
o x - 1 y + k =0 ...(i)
The equation (i) is Paases through the point ( -3,-2)
0 ( -3) -1(-2) + k =0
2 + k =0
k = -2
∴The equation of the perpendicular line to the given line is
put k = -2 in equation (i)
o x - 1 y + k =0
- y +(-2) =0
- y = 2
y = -2
Final answer:-
∴The equation of the perpendicular line to the given line is y =-2
Halla la suma de los infinitos términos de la progresión geométrica si r= 1/5 y a1=1/2
Answer:
5/8
Step-by-step explanation:
Aquí, queremos encontrar la suma al infinito de la progresión geométrica, dado el primer término y la razón común Matemáticamente, eso sería;
S = a/1-r
S = 1/2/(1-1/5)
S = 1/2/4/5
S = 1/2 * 5/4
S = 5/8
Weber's Mail Manufacturing is a company that produces chain mail. Their most popular product is saw-cut metal links that hobbyists can use to make their own creations. The company recently spent $600 on advertising, which they hope to make back quickly. The wire used to produce one ounce of links costs $1, but the finished links sell for $4 per ounce. Eventually, the company will make back its investment and break even. What will their expenses and sales both equal?
Answer:
Their expenses and sales will both equal at 200 ounces.
Step-by-step explanation:
This can be determined using the break-even point in ounce formula as follows:
Break even point in ounce = Fixed cost / Contribution per ounce
Where;
Fixed cost = Advertising = $600
Contribution per ounce = Selling price per ounce - Cost per ounce = $4 - $1 = $3
Substituting the values into equation (1), we have:
Break even point in ounce = $600 / $3 = 200 ounces
Therefore, their expenses and sales will both equal at 200 ounces.
A telephone poll of an SRS of 1234 adults found that 62% are generally satisfied with their lives. The announced margin of error for the poll was 3%. Does the margin of error account for the fact that some adults do not have telephones
Answer:
No. The margin of error only includes sampling variability.
Step-by-step explanation:
The margin of error would be considered for the sampling error
In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error
The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors
So there is no margin of error as it only involved the variability in the sampling

The perimeter of a rectangular room is 52 feet. The length is 2 more than the width. What is the width of the room?
A. 10 feet
B. 14 feet
C. 13 feet
D. 12 feet
Answer:
10
Step-by-step explanation:
i think its 10 maybe cuz if u see
the perimeter of a rectangular room is 52 feet. right?
then then height is 2 more than the width. what is the width of the room? so am I right copying the question? yes the question is right copied ok!
now see when u subtract 2 from 12 it gives u 10 and length i as 2 more than the width so maybe 10
A construction crew has just finished building a road. The crew worked for 4 1/5 days. If they built 2 1/3 kilometers of road each day, what is the total length of road they built?
Answer:
9.8
Step-by-step explanation:
The crew worked for 4 1/5 days
They built 2 1/3 kilometres of road each day
Therefore the total length of the road can be calculated as follows
= 4 1/5 × 2 1/3
= 21/5 × 7/3
= 147/15
= 9.8
Hence the length of the road is 9.8 kilometres
A car manufacturer produced 5,000 cars for a limited edition model. Dealers sold all of these cars at mean price
of $36,000 with a standard deviation of $3,000. Suppose we were to take random samples of 9 of these cars
and calculate the sample mean price z for each sample.
Calculate the mean and standard deviation of the sampling distribution of 2.
H(x)=_________dollars
O(x)=_________dollars
Answer:
μₓ = 36,000 dollars
σ ₓ= 1,000 dollars
Step-by-step explanation:
to find μₓ = 36,000 dollars:
Look in the question, it states that the mean is $36,000.
to find σ ₓ= 1,000 dollars:
[tex]\frac{3000}{\sqrt{9} } = 1000[/tex]
The mean and standard deviation of the sampling distribution is $36000 and $1000.
What is Standard Deviation?
The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Given:
The mean and the standard deviation of the sampling distribution of the sample mean:
Mean, [tex]\mu[/tex] = $36000
[tex]\sigma[/tex] = 3000
n = 9
So, standard deviation of the sampling distribution
= [tex]\sigma[/tex] / √n
= 3000 / √9
= 3000/3
= 1000
Hence, Mean = $36,000 and standard deviation = $1000.

A bird starts at 20m and changes to 16m? The bird's final elevation is
Answer:
Kindly check explanation
Step-by-step explanation:
The initial elevation is 20m
According to the question :
If it changes to 16m, then the final elevation of the bird is 16 m.
However, in some texts, the question goes thus;
A bird starts at 20m and changes 16m? The bird's final elevation is?
In this case, the initial height = 20m
Change in height = 16 m (positive means ascension)
Hence,
initial height + change in height
20 m + 16 m
= 36m
