Answer:
[tex]x=20[/tex]
Step-by-step explanation:
Refer to the diagram below for letter names of points.
Using the theorem provided on the second image, we can conclude that [tex]m\angle AOC=2*m\angle ABC=2*100\textdegree = 200\textdegree[/tex]. Keep in mind that this is the reflex [tex]\angle AOC[/tex].
Because [tex]O \in DC[/tex], we know that [tex]DC[/tex] is a diameter by definition, which makes [tex]m\angle DOC = 180\textdegree[/tex].
Using the Angle Addition Postulate, we can write the following equation:
[tex]m\angle AOD+m\angle DOC=m\angle AOC[/tex]
Substituting the measures of each angle into the equation gives us:
[tex]x\textdegree + 180\textdegree = 200\textdegree[/tex]
Solving the equation for [tex]x[/tex] gives us:
[tex]x\textdegree + 180\textdegree = 200\textdegree[/tex]
[tex]x\textdegree + 180\textdegree - 180\textdegree = 200\textdegree - 180\textdegree[/tex] (Subtract [tex]180\textdegree[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]x\textdegree = 20\textdegree \rightarrow \bf x=20[/tex] (Simplify)
Remember that [tex]x=20[/tex], not [tex]20\textdegree[/tex] because the degree symbol was already given in the original expression. Hope this helps!

Một ôtô đi từ A đến B với vận tốc 60km/h và đi từ B về A với vận tốc 45km/h. Thời gian cả đi và về hết 7giờ. Tính quãng đường AB
Please explain in english
Answer:
Đáp án: 180km
Step-by-step explanation:
Giải thích các bước giải:
Gọi quãng đường AB là x (km)
(x > 0)
Thời gian ô tô đi từ A -> B là x/60 (h)
Thời gian ô tô đi từ B -> A là x/45 (h)
Vì thời gian cả đi và về hết 7h
=> x/60 + x/45 = 7
=> x = 180 (TM)
Vậy quãng đường AB là 180 km

The sum of twice a number and 13 is 75.
Answer:
The value of this number is 31.
Step-by-step explanation:
To solve this you could set up an equation and solve for x.
Sum means add, so you are going to add 2n and 13 to get 75.
2n + 13 = 75
Subtract 13 from both sides.
2n = 62
To get n alone, divide by 2 on both sides.
n = 31
The value of this number is 31.

A person walks on average 4000 steps per day. If one step is about 2 feet long, how much would the average person walk per week? HELP
Answer:
56000 ft
Step-by-step explanation:
4000 steps a day.
7 days in a week.
2 ft per step
so, we calculate how many steps in a week
4000 × 7 = 28000
and then we calculate the distance by saying each of these steps is 2 ft
so,
28000 × 2 = 56000 ft
as a little extra thought :
there are 5280 ft in a mile.
so, the person walks
56000 / 5280 miles = 10.61 miles
in a week.

Step-by-step explanation:
Add the x's together
So the problem is 6x + 1 =
This is a triangle so it = 180
6x + 1 = 180
__________
Subtract 1 from itself so 6x crosses out
Then subract 1 from 180
Which = 179
Now, divide 6 from both sides 6x is crosses out
You are left with x = (the number you got when dividing 179 / 6)
125 Children get one pen, there are 8
pens in a pack. How many pens are
needed?
Answer:
16 packs
Step-by-step explanation:
Take the number of children and divide by the number of pens in a pack
125/8
15.625
We need to round up to get the number of packs
16 packs
Answer:
125 pens and 16 packs.
Step-by-step explanation:
Given:
Each child gets 1 pen.There are 125 children.Each pack has 8 pens.Each child gets 1 pen, so there needs to be 125 pens.
Since there are 8 pens in a pack, there will need to be:
125 / 8 = 15.62
Estimate:
16 packs
There needs to be 16 packs for the 125 children.
round 1.89 to one decimal place
Answer:
1.9
Step-by-step explanation:
You round when the numbers behind the decimal are 5 or greater. This being said, you need to round from the number furthest away from the decimal. In this case it would be 9. 9 is greater than 5 so we round 8 up to 9 and get rid of the number behind it. We are left with 1.9

Bryan is getting trained and licensed to be a truck driver. He only has $350 in his bank account. The training is free but gas costs 13 cents per mile. If he travels 1,254 miles, how much money will he have left in his bank account?
A. $186.98
B. $127.32
C. $64.83
D. $206.17
Answer:
186.98
Step-by-step explanation:
The cost of gas is the cost per miles times the number of miles
1254 * .13
163.02
Subtract this from the amount in the bank account
350-163.02
186.98

Step-by-step explanation:
(a+2b)^2
(a+2b)(a+2b)
FOIL
first: a*a = a^2
outer: a*2b = 2ab
inner: 2b*a = 2ab
last: 2b*2b = 4b^2
Add them together
a^2 +2ab+2ab+4b^2
Combine like terms
a^2 +4ab+4b^2
Answer:
Solution given:
(a+2b)²
we have
by using formula
(a+b)²=a²+2ab+b²
so
we get
a²+2*a*2b+(2b)²
=a²+4ab+4b²
Solve d−85=p for d .
Answer:
d = p + 85
Step-by-step explanation:
We don't have a lot to go on for this problem. We have two undefined variables.
In order to solve for d, we need to isolate it:
d - 85 = p
Add 85 to both sides
d = p + 85

pls mark my answer as the brainliest
The area of square of side 3X is 72 square unit.
What is square?The square is a 4 sided figure, each side of the square is equal and make a right angle.
The area of square having sided a unit can be given by a² square unit.
Given that,
Area of square having side X is 8.
Since, formula for area of square having side X is X².
Implies that,
X² = 8
X = 2√2
The area of square having side 3X
side =3 × 2√2
side = 6√2
The area of square = (6√2)²

A student is assessing the correlation between the number of hours a plant receives sunlight and the height to which it grows. The table shows the data:
Number of hours of sunlight
(x) 0 1 2 3 4 5 6 7 8 9
Height of plant in cm
(y) 4 7 10 13 16 19 22 25 28 31
Part A: Is there any correlation between the number of hours of sunlight that a plant receives and the height to which it grows? Justify your answer. (4 points)
Part B: Write a function that best fits the data. (3 points)
Part C: What does the slope and y-intercept of the plot indicate about the plant? (3 points)
Answer:
Hello,
Step-by-step explanation:
Part A:
Yes
Since
y=f(x)
f(0)=4
f(1)=7 : f(1)=f(0)+1*3
f(2)=10= 7+3 : f(2)=f(1)+3 =f(0)+2*3
f(3)=13=10+3: f(3)=f(2)+3=f(0)+3*3
...
f(9)=31=28+3=f(8)+3=f(0)+9*3
f(n)=f(0)+n*3=4+n*3
Part B: y=3x+4
Part C: slope=3 , y-intercept=4
The slope indicate the grow of the plant (how many cm does it grow in function of the height it receives)
y-intercept indicate the original height of the plant.

Answer:
-8 5/20 , 4/25 , 9/20
Step-by-step explanation:
If there are negative numbers, those are the least. Let's say the number was -2 and -1. With a positive integer, 2 would be greater, but since it's negative, it's the least. SO -8 and 5/20 would be the least. Then putting the other two fractions into decimal form, or you can find the greatest common denominator, you'll find that 9/20 is greater than 4/25.
