Answer:
[tex] m\angle D = 40\degree[/tex]
Step-by-step explanation:
[tex] m\angle DEC = 25\degree [/tex]
(Vertical angles)
[tex] m\angle DCE = 180\degree - 65\degree [/tex]
(Linear pair angles)
[tex] m\angle DCE = 115\degree [/tex]
In [tex] \triangle DCE[/tex]
By interior angle sum postulate of a triangle
[tex] m\angle D = 180\degree-(115\degree + 25\degree) [/tex]
[tex] m\angle D = 180\degree-140\degree[/tex]
[tex] m\angle D = 40\degree[/tex]

Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $ 100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below. Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance. Natasha uses the $25 off the repair cost coupon first. She then uses the %20% off the repair cost coupon on the remaining balance.

If you read 340 pages in 45 minutes how many pages do read in 1 minute
Answer:
7 5/9
Step-by-step explanation:
340/45 = 7 5/9
Answer:
7.6 pages
Step-by-step explanation:
Okie, so this is a standard unit rate problem, so what you're going to do is divide the number of whatever, in this case, pages, by the time, so:
340 ÷ 45 = 7.6 (rounded)
So you read 7.5 pages per minute
(which is pretty impressive if it's a chapter book)

answer for brainlest and 25 points
Answer:
Order from greatest to least: 10.5, [tex]3\pi +1[/tex], [tex]\sqrt{105}[/tex]
Step-by-step explanation:
step 1 simplify each number
3π + 1 = 10.4247779
*round to the nearest tenth*
3π + 1 = 10.4
[tex]\sqrt{105} =10.2469507[/tex]
*round to the nearest tenth*
[tex]\sqrt{105} =10.2[/tex]
10.5 = 10.5
Now that we have simplified each number we can easily put them in order from greatest to least
10.5 is the greatest number
10.4 is the middle number
10.2 is the lowest number
so 10.5, 10.4, 10.2
Now we put them back in the original form
10.5 = 10.5
10.4 = 3π + 1
10.2 = [tex]\sqrt{105}[/tex]
Your answer is
10.5 , 3[tex]\pi[/tex] + 1, [tex]\sqrt{105}[/tex]

which of the following correctly gives the center and radius of the circle defined by the equation (z-7)^2 = 10?
Answer:
Center (7,2); Radius - Square Root of 10
Step-by-step explanation:
Equation for a Cricle:
(x−h)^2 + (y−k)^2 = r^2
Where:
h = x-coordinate of the center of the circle
k = y-coordinate of the center of the circle
r = radius of the circle
For this problem, your h = 7, k = 2, and r = square root of 10

determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution. x+y=5 2x-y=-3
Answer:
(2/3, 13/3) (Exactly one solution)
Step-by-step explanation:
Write these equations in a column:
x+y=5
2x-y=-3
Note that we can eliminate y immediately by adding these two equations together. We get:
3x = 2, so that x = 2/3.
Substituting 2/3 for x in the first equation, we get:
2/3 + y = 5. Clear out fractions by multiplying all three terms by 3:
2 + 3y = 15, or 3y = 13. Then y = 13/3, and the solution is
(2/3, 13/3) There is exactly one solution.

The radius of a circle is 10 inches. What is the angle measure of an arc bounding a sector with area 10π square inches?
Answer:
Step-by-step explanation:
hello :
the arc length formula is : s = 2πr(θ/360°)
given : area : s = 10 , radius : r = 10
2(3.14)(10)(θ/360°)=10 solve for : θ
2(3.14)(θ/360°)=1
θ = 360°/6.28
θ = 57°.32

Answer:
5 hours
Step-by-step explanation:
distance = rate x time
t = time
(700-375) = 65t
325 = 65t
325/65 = t
5 hours = t

4.Find the length of the diagonal of a rectangle having dimensions 16 cm and 12 cm.
Answer:
20 cm
Step-by-step explanation:
So from the problem we get that the two sides of the rctangle are 16 cm 12 cm which are base perpendicular of the right angle triangle. H = 20 cm. So the diagonal of the rectangle = 20 cm.
Answer:
20 cm
Step-by-step explanation:
Here's your solution
=> length of rectangle = 16 cm
=> width of rectangle = 12 cm
=> Diagonal of rectangle = √(l^2 + w^2 )
=> Diagonal = √(16^2 + 12^2)
=> Diagonal = √(256 + 144)
=>. Diagonal = √400
=> Diagonal = 20 cm

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?
(x – 9)2 + (y + 4)2 = 25
(x + 4)2 + (y – 9)2 = 25
(x – 9)2 + (y + 4)2 = 100
(x + 4)2 + (y – 9)2 = 100
Answer:
(x + 4)^2 + (y – 9)^2 = 25
Step-by-step explanation:
The standard form for a circle is
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] where (h, k) is the center and r is the radius
In your case, h = -4 and k = 9 and r = 5
So, (x + 4)^2 + (y – 9)^2 = 25
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
Data
h = -4k = 9r = diameter/2 = 10/2 = 5Equation of CircleThe equation of circle is given by
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Let's substitute our values and get our equation
[tex](x--4)^2 + (y-9)^2 = 5^2\\(x+4)^2 + (y-9)^2 = 25[/tex]
we substituted the values of h and k and made sure it's in the standard form of equation of a circle.
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
This looks exactly like
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
