340
D
B
A
A 56°
B 340
C 68°
D 170
Answer:
68°
Step-by-step explanation:
Since, angle subtended on the circumference of the circle is half angle subtended on the center of the circle.
[tex] \therefore m\angle DBR = \frac{1}{2} \times m\angle DAR\\\\
\therefore 34\degree = \frac{1}{2} \times m\angle DAR\\\\
\therefore 34\degree \times 2= m\angle DAR\\\\
\therefore 68\degree = m\angle DAR\\\\
\therefore m\angle DAR=68\degree[/tex]
You have eaten 70% of your Halloween candy. You counted all the empty wrappers and you count 140 empty wrappers !!! How many peices of candy did you have to begin with ?
Answer:
200 pieces of candy.
Step-by-step explanation:
Let x represent the amount of candy we had to begin with.
We ate 70% or 0.7 of our starting amount x.
After eating 70% of x, we are left with 140 empty wrappers.
Therefore, 70% or 0.7 of x is 140. So, we can write the following equation:
[tex]0.7x=140[/tex]
To find the original amount of candy, we just have to solve for x.
So, let’s divide both sides by 0.7:
[tex]\displaystyle x=\frac{140}{.7}=200[/tex]
Therefore, we started out with 200 pieces of candy.

Period 5 is gearing up for a class ice cream party. Meghan plans to arrange the party and understands that ice cream cones cost $1.10 and sundaes cost $2.35. On the day of the party the receipt shows a total of 172 cones and sundaes were $294.20. How many cones were sold?
Answer: 88 cones.
Step-by-step explanation:
We know that:
price of a cone = $1.10
price of a sundae = $2.35
A total of 172 cones and sundaes were sold for $294.20
Then we can define two variables:
C = number of cones sold
S = number of sundaes sold.
C + S = 172 (the total number of sundaes and cones sold is 172)
C*$1.10 + S*$2.35 = $294.20 (that is how much the won).
Then we have the system of equations:
C + S = 172
C*$1.10 + S*$2.35 = $294.20
And we want to find how many cones were sold.
To solve this, we first need to isolate the other variable, S, in one of the equations, i will isolate S in the first equation:
S = 172 - C
Now, let's replace this in the second equation:
C*$1.10 + (172 - C)*$2.35 = $294.20
Now we can solve this for C, and find the number of cones that were sold.
C*$1.10 + $404.20 - C*$2.35 = $294.20
C*($1.10 - $2.35) = $294.20 - $404.20
-C*1.25 = -110
C = 110/1.25 = 88
88 cones were sold.
Your friend decided to join a bmx course so he can race with his friends. The
courses charges $7 per race after the membership fee. Your friend has raced 28
times and paid a total of $210, including the membership fee. What is the
membership fee? How much would he pay if he races 39 times? *
Answer:
He would pay $287 if he races 39 times
Thus, the membership fee is $14.
Step-by-step explanation:
Linear Modeling
The situation described in the problem can be modeled as the equation of a line which has the form:
[tex]y=ax+b[/tex]
Where y is the cost of the course, x is the number of races, a is the cost per race, and b is the membership fee.
We know the course charges $7 per race, so a=7. Since your friend has raced x=28 times and paid y=210, we can find the value of b:
[tex]210=7(28)+b[/tex]
Operating:
[tex]210=196+b[/tex]
b=14
Thus, the membership fee is $14.
The linear model is now:
[tex]y=7x+14[/tex]
If he races x=39 times, your friend would pay:
[tex]y=7(39)+14=287[/tex]
y=287
He would pay $287 if he races 39 times

The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of Earth from the Sun is 1.5 ⋅ 108 kilometers. About how many more kilometers is the distance of Earth from the Sun than the distance of Mercury from the Sun?
4.3 ⋅ 107 kilometers
9.2 ⋅ 107 kilometers
9.2 ⋅ 108 kilometers
5.7 ⋅ 109 kilometers
Answer:
If you take a look at, 1.5 kilometers you can see that Mercury from the Sun is 5.8, it is also asking how many more kilometers is the distance of earth, so if you look at 5.1 and D which is 5.7 you would add those last digits together and get 5.8 so therefore your answer could possibly be D) 5.7 ⋅ 109 kilometers

Complete the point-slope equation of the line through (-5,7)(−5,7)left parenthesis, minus, 5, comma, 7, right parenthesis and (-4,0)(−4,0)left parenthesis, minus, 4, comma, 0, right parenthesis.
Answer:
The equation of line in point-slope form is: [tex]y-7 = -7(x+5)[/tex]
Step-by-step explanation:
Given points are:
(x1,y1) = (-5,7)
(x2,y2) = (-4,0)
Point slope form of equation is given by:
[tex]y-y_1 = m(x-x_1)[/tex]
Here m is the slope
The slope is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Putting the values we get
[tex]m = \frac{0-7}{-4+5}\\m = \frac{-7}{1}\\m = -7[/tex]
Putting in the equation we get
[tex]y-y_1 = -7(x-x_1)[/tex]
Putting (-5,7) in the equation
[tex]y - 7 = -7\{x-(-5)\}\\y-7 = -7(x+5)[/tex]
Hence,
The equation of line in point-slope form is: [tex]y-7 = -7(x+5)[/tex]

What do you add to 43/6 to make 7
Answer:
1/6 that's the answer
Step-by-step explanation:
so you do 43/6-7=43/6-42/6=1/6
Answer:
Actually the answer is -⅙
Step-by-step explanation:
43/6 written differently is 7 ⅙, because the fraction 42/6 is the same as 7 (42÷6=7). But since your number is 43/6 you get
7 1/6.
your original number is larger than 7 but the question was what number you have to "add" to get to 7. so they number has to be a negative number.
like this:
43/6 + (-1/6) = 42/6. which you rewrite now as
43/6 - 1/6 = 42/6. and I explained that 42/6 is the same as 7.
Divide. Reduce the answer to lowest terms.

Step-by-step explanation:
Tyler is packing his bags for vacation. He plans to pack two outfits for each day of vacation.
Let d = the number of days of his vacation.
Write an expression for the total number of outfits WILL BRIANLIST
=========================================
Work Shown:
d = number of days of his vacation
1 day = 1*2 = 2 outfits
2 days = 2*2 = 4 outfits
3 days = 3*2 = 6 outfits
4 days = 4*2 = 8 outfits
5 days = 5*2 = 10 outfits
and so on.
In general we can say,
d days = d*2 = 2d outfits
d is simply a placeholder or a box where we'll place a number inside. For example, if he's on vacation for d = 7 days, then he'll bring 2*d = 2*7 = 14 outfits.
The expression 2*d is the same as 2d. We can leave out the multiplication sign since having a number next to a variable like this implies multiplication.
The expression for the total number of outfits is 2d
The total number of outfits Tyler plans to pack for his vacation can be expressed as 2 multiplied by the number of days of his vacation, which we'll denote as 'd'. Since Tyler plans to pack two outfits for each day, multiplying 'd' by 2 will give us the total number of outfits.
In this expression, 'd' represents the number of days of Tyler's vacation, and multiplying it by 2 accounts for the two outfits planned for each day. This expression allows us to calculate the total number of outfits based on the length of Tyler's vacation.
For example, if Tyler's vacation is 7 days long, the expression 2d would yield:
2 * 7 = 14
Therefore, Tyler would plan to pack 14 outfits for his 7-day vacation. The expression 2d allows flexibility to calculate the total number of outfits based on the specific number of vacation days.
