Answer:
m∠ADC=55°
Step-by-step explanation:
step 1
Find the value of x
we know that
m∠CDE+m∠EDF=180° ----> by supplementary angles (form a linear pair)
substitute the given values
[tex](2x+1)\°+(x-7)\°=180\°[/tex]
solve for x
[tex]2x+x=180+6[/tex]
[tex]3x=186[/tex]
[tex]x=62[/tex]
step 2
Find the measure of angle ∠ADC
we know that
m∠ADC=m∠EDF ----> by vertical angles
m∠EDF=(x-7)°
substitute the value of x
m∠EDF=(62-7)°=55°
therefore
m∠ADC=55°

Answer:
Part 1) [tex]x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})[/tex]
Part 2) [tex]x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})[/tex]
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
[tex]ax^{2} +bx+c=0[/tex]
is equal to
[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]
Part 1)
in this problem we have
[tex]x^{2} -2x-2=0[/tex]
so
[tex]a=1\\b=-2\\c=-2[/tex]
substitute in the formula
[tex]x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}\\\\x=\frac{2(+/-)\sqrt{12}} {2}\\\\x=\frac{2(+/-)2\sqrt{3}} {2}\\\\x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}\\\\x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}[/tex]
therefore
[tex]x^{2} -2x-2=(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))[/tex]
[tex]x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})[/tex]
Part 2)
in this problem we have
[tex]x^{2} -6x+4=0[/tex]
so
[tex]a=1\\b=-6\\c=4[/tex]
substitute in the formula
[tex]x=\frac{-(-6)(+/-)\sqrt{-6^{2}-4(1)(4)}} {2(1)}[/tex]
[tex]x=\frac{6(+/-)\sqrt{20}} {2}[/tex]
[tex]x=\frac{6(+/-)2\sqrt{5}} {2}[/tex]
[tex]x_1=\frac{6(+)2\sqrt{5}}{2}=3+\sqrt{5}[/tex]
[tex]x_2=\frac{6(-)2\sqrt{5}}{2}=3-\sqrt{5}[/tex]
therefore
[tex]x^{2} -6x+4=(x-(3+\sqrt{5}))(x-(3-\sqrt{5}))[/tex]
[tex]x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})[/tex]

The student council is selling Candy bars to earn money towards their budget for the school dance explain why the number of candy bars is the independent variable
Answer:
the number of candy bars they have is not affected by the other factors like the budget or the student council
Final answer:
The number of candy bars is the independent variable because it can be manipulated or changed by the student council to affect the amount of money they earn.
Explanation:
The number of candy bars is considered the independent variable in this scenario. The independent variable is the one that is manipulated or changed in an experiment, and its value does not depend on any other variable.
In this case, the student council is selling candy bars to earn money for their budget, and the number of candy bars they sell is the variable that they have control over.
By increasing or decreasing the number of candy bars sold, they can affect the amount of money they earn for their budget.
solve the equation y=11.3x + 13.8 estimates the amount that businesses will spend, in billion of dollars on a certain business technology where x is the number of years after 2000 for what years will the spending be more than $59 billion where spending will be more than $59 billion more than blank years after 2000
Answer:
Spending will be more than $59 billion more than 4 years after 2000.
Step-by-step explanation:
Given:
[tex]y=11.3x + 13.8[/tex]
x is the number of years.
Business spending is $59 billion.
Hence we can say that y = $59.
Now Substituting the value of y in above equation we will find the value of x in number of years.
[tex]11.3x+13.8=59\\11.3x=59-13.8\\ 11.3x= 45.2\\\\x=\frac{45.2}{11.3} = 4 years.[/tex]
Hence we can say that,
After 4 years after 2000 the spending will be more than $59 billion.
or
Spending will be more than $59 billion more than 4 years after 2000.
The equation demonstrates that the spending will exceed $59 billion more than 4 years after 2000.
Explanation:To solve the problem, we first need to set the equation y = 11.3x + 13.8 to greater than 59, as we are trying to find out when the spending will be more than $59 billion. The equation will therefore be, 11.3x + 13.8 > 59.
Then, we subtract 13.8 from both sides of the equation to isolate the term with x, resulting in 11.3x > 45.2.
Finally, we divide each side by 11.3 to solve for x, which will give us x > 4. Consequently, the spending will be more than $59 billion more than 4 years after 2000.

Danielle has $6.65 worth of change in nickels and dimes. If she has 5 times as many nickels as dimes, how many of each type of coin does she have?
Answer:
95 nickels 19 dimes
Step-by-step explanation:
d=dimes
5d=nickels
0.05(5d) + 0.10(d) = 6.65
0.25d + 0.10d = 6.65
0.35d=6.65
Divide by 0.35
d= 19 (19 coins)
19 dimes =$1.9
6.65-1.9= $4.75
Nickels=$4.75
4.75/0.05 = 95 coins
19*5=95
114 coins in total
19*0.10 = 1.9
95*0.05=4.74
4.75+1.9= 6.65
Answer:
There are 19 dimes and 95 nickels
Step-by-step explanation:
Represent the numbers of nickels and dimes by n and d. Then n = 5d.
The value of the nickels is $0.05n and that of the dimes is $0.10d. Together these two amounts come to $6.65:
$0.05n + $0.10d = $6.65.
But n = 5d.
Substituting 5d for n, we get:
$0.05(5d) + $0.10d = $6.65
Combining the two terms on the left, we get:
0.25d + 0.10d = 6.65, or
0.35d = 6.65.
Solving for d, we get d = 6.65/0.35, or d = 19. Since n = 5d, n = 5(19) = 95.
There are 19 dimes and 95 nickels.

the total heigh of bill mary and rob is 180 cm bob is twice as tall as bill and mary is 28 cm taller than bill how tall is rob
Answer:
Rob is 76 cm tall.
Step-by-step explanation:
Let b = height of bill.
Let m = height of Mary.
Let r = height of Rob.
"the total heigh of bill mary and rob is 180 cm"
b + m + r = 180 Equation 1
"bob* is twice as tall as bill"
*I think you meant Rob is twice as tall as Bill.
r = 2b
"mary is 28 cm taller than bill"
m = b + 28
Substitue r = 2b and m = b + 28 into Equation 1.
b + b + 28 + 2b = 180
4b + 28 = 180
4b = 152
b = 38
r = 2b
r = 2(38) = 76
Rob is 76 cm tall.
Rob height is 76cm.
Given that,
Total height of Bill, Mary and Rob is 180cm.Rob is twice tall as Bill.Mary is 28cm taller than Bill.We need to find the height of Rob.According to the given data, computation of the data are as follows,
Let Bill height be X, then Rob height is 2X and Mary height is X + 28.
So, X + 2X + X + 28 = 180cm
4X = 180 - 28
X = 152 [tex]\div[/tex] 4
X = 38
Hence, Bill height = X = 38cm
Rob height = 2X = 76cm
Mary height = X + 28 = 66cm

Which equation models the height of the plant, y, after x days?
A. y+35 = 2(x+10)
B. y - 35 = 2(x - 10)
C. y - 10 = 2(x - 35)
D. y - 35 = 1/2 (x - 10)
Answer:
B. y - 35 = 2(x - 10)
Step-by-step explanation:
The height of the plant, y, after x days could be modeled by the equation
y-y0=k(x-xo) (1),where y0 was the initial height at 'x0'th. day, and k is the constant of proportionality.From equation (1), k could be evaluated as follows:k=(y-y0)/(x-x0) From the problem statement, we may determine k by plugging in the given values, e.g. y0= 35, x0=10, y=55, x=20.Thus,k=(55-35)/(20-10)=2Therefore, the model equation becomesy-35=2(x-10)Answer:
