Answer:
44 degrees
Step-by-step explanation:
Triangles ABC and DBC are congruent (as said in the question), that would make the corresponding parts of the two triangles congruent.
Answer:
Angle D = 44° (degrees)
Step-by-step explanation:
given that ∆ABC is congruent to ∆DBC, AB = 10, and Angle A = 44°. Angle D must be 44° as well since you can tell that angle abc is 88° and is not a right angle, and due to the corresponding parts. You can also think about these triangle as angles since angle abc = angle dbc. The other angles can be calculated using the triangle sum theorem since both triangles share side bc so angle acb and dcb are right angles(90°)
therefore 180-(44+90) = 46° which the measure of angles abc and dcb.
This measure would only make it true because of triangle congruency.

Stefan estimates the income and expenses for renting
a phone accessory store in the mall. He enters the
amounts in the table below. Should Stefan
rent a phone accessory store? Explain.
Answers
Answer/Step-by-step explanation:
If total income is more than total expenses, she should rent it. If the total income is less than the total expenses, she should not rent it.
Total income estimated in a month:
Sales: $950 per week = 950*4weeks = $3,800 per month
Services: $2,875 per month
Total estimated income per month = $(3,800 + 2,875) = $6,675
Total expenses estimated in a month:
Rent: $4,500 per month
Travel: $7.5 per day = 7.5*7days = $52.5 per week.
Assuming there are 4 weeks in a month, expenses for travel in a month will be:
$52.5*4 = $210
Merchandise: $1,650 per month
Total expenses estimated per month = $(4,500 + 210 + 1,650) = $6,360
Total estimated income ( > total estimated expenses in a month, therefore, Stefan should rent the phone accessory store. She will make profit.

5.5
Step-by-step explanation:
if you order the number from least to greatest like this 0,1,2,2,5,5,6,6,6,7 the median is the median number so here the median is 5.5 the reason it is 5.5 is bc the middle number is 5 and 6 and the middle number of that is 5.5

7. Carlos is renovating a house and hires a plumber to install the piping for 4 points
the new bathroom. The plumber charges an initial fee plus an hourly rate
for the number of hours it will take to complete the installation. The
function y = 100 + 35x can be used to model the total cost of the job, in
dollars. What does the slope in the expression of this function represent? *
the initial fee for the installation, $35
the initial fee for the installation, $100
the cost per hour of installation work, $35
the number of hours to complete the installation, x
Answers
Answer:
the cost per hour of installation work, $35
Step-by-step explanation:
y = 35x + 100
the slope of a function is the coefficient of x, therefore, it is 35. $100 is the initial fee, since it ia the y intercept, and $35 is the cost per hour. y is the total amount, and x is the number of hours. Therefore, the only possible answer is the third choice,
Write the point-slope form of the line that passes through (-8, 2) and is perpendicular to a line with a slope of -8. Include all of your work in your final answer. Type your answer in the box provided to submit your solution.
Answers
Answer:
y - 2 = 1/8(x+8)
Step-by-step explanation:
The slope of lines that are perpendicular are each other's opposite reciprocal.
so, the reciprocal of -8 = -1/8, then find the opposite of -1/8 which is 1/8.
Point-slope form : y - y1 = m(x - x1)
(x1,y1) = (-8,2)
so, y - 2 = 1/8(x+8) is our final answer!

Answers
Answer:
68.2
Hope this helps. :)
Answer:
I believe it would be 65?
Step-by-step explanation:
if if I divide 22 by 100 I will get 2.2.
And at 5 + 2 that means if you combine the blue flowers and yellow flowers you will get $7 in total.
And there's 15 red flowers 7 is kind 40 of 15 which is 100 because. 8+7=15 .
And for 15 to be completely split in half it would have to be 7.5.
But that's not how it works so if we put 8 & 7 into percents 8 would be 65 and 7 would be 35
Hailey is putting up a fence in the shape of an isosceles triangle in her backyard. The fence has side lengths as shown, where x represents the number of feet in each fence section. The perimeter of the fence can be covered using 8 total fence sections represented by the expression 8x. If fencing costs $6.50 a foot, what would be the total cost of the fence?
Answers
Answer: The total cost would be $780.00
The expression for the total cost of fencing is $52x , where x is a variable representing the number of feet in one section.
What is an expression in one variable?An expression in one variable is a statement formed by the using constants and an unknown variables and mathematical operators but sign is equal to is not used. Expression in one variable is linear if the power of the unknown variable is equal to one .
Given that number of feet in one fence section be x
No of feet in 8 such fence section = 8x
Given , Perimeter = 8 fence sections = 8x feet
Cost of fencing of one foot = $6.50
Cost of fencing 8x feet = 8x * 6.50
Therefore , the total cost of the fencing can be given by = 8x*6.50
= $ 52 x
Thus, the expression for the total cost of fencing is $52x

Answers
Answer:
The answer is Beth.
Step-by-step explanation:
It states "Becky is not Sleeping Beauty and went trick-or-treating with Snow White" so we know that its not Becky. It also states "Beth and Sleeping Beauty are sisters" so we know that Beth is not Sleeping Beauty and we know that Becky is not Sleeping Beauty or Snow White. So it means that Barbara is Sleeping Beauty, Becky is Cinderella and Beth is Snow White.

f(a) = a3 – 4a2 + a + 6
f(x) = x3 – x2 – 4
Answers
Answer:
Explained below
Step-by-step explanation:
Polynomial Roots
If x=a is a root of f(x), then f(a)=0
We will test the following functions to check if a=2 is a root.
[tex]h(m)=8-m^3[/tex][tex]h(2)=8-2^3=8-8=0[/tex]
Thus m=2 is a root of h
[tex]f(g)=g^3-2g^2+g[/tex][tex]f(2)=2^3-2\cdot 2^2+2[/tex]
[tex]f(2)=8-2\cdot 4+2=8-8+2=2[/tex]
Thus g=2 is not a root of f
[tex]f(a) = a^3 - 4a^2 + a + 6[/tex][tex]f(2) = 2^3 - 4\cdot 2^2 + 2 + 6[/tex]
[tex]f(2) = 8-16+8=0[/tex]
Thus a=2 is a root of f
[tex]f(x) = x^3 - x^2 - 4[/tex][tex]f(2)=2^3 - 2^2 - 4[/tex]
[tex]f(2)=8 - 4 - 4=0[/tex]
Thus x=2 is a root of f

c. g(x) = |5x|
d. g(x) = 5 |x|
Answers
Answer: I’m thinking the answer is B
Step-by-step explanation:
Transformations are used to move a function from one position to another. The function of g(x) is [tex]g(x) = |\frac x5|[/tex]
Given that:
[tex]f(x) = |x|[/tex]
The rule of a horizontal stretch by factor k is:
[tex](x,y) \to (\frac xk,y)[/tex]
This means that:
[tex]g(x) = f(\frac xk)[/tex]
In this case, [tex]k = 5[/tex]
So, we have:
[tex]g(x) = f(\frac x5)[/tex]
Calculate [tex]f(\frac x5)[/tex]
[tex]f(\frac x5) = |\frac x5|[/tex]
Hence, the function of g(x) is
[tex]g(x) = |\frac x5|[/tex]
