Write an explicit formula for An, the nth term of the sequence 33, 36, 39,
Answer:
30 + 3n
Step-by-step explanation:
33 , 36 , 39 .......
This is an arithmetic series
First term = 33
Common difference (d) = Second term - first term
= 36 - 33 = 3
Nth term = a + (n -1)* d
= 33 + ( n-1) * 3
= 33 + n*3 - 1*3
= 33 + 3n - 3
= 33 - 3 + 3n
= 30 + 3n

PLS HELP ILL GIVE BRAINLIEST (SAT Prep) Find the value of x
Answer:
x = 24
Step-by-step explanation:
Act like it one triangle that has angle 94 and 41 but not the corner
all 3 angle of a triangkle equal 180
so to fine the missing corner you sub tract 180 by 94 and 41 (45)
Now that we know that angle we can find x for the small angle
180 - (111 + 45) = 24

The perimeter of a triangle is 53 meters. Side a is three less than side b and side c is twice side b.
Answer:
a = 11
b = 14
c = 28
Step-by-step explanation:
a+b+c = 53
b-3 = a
c = 2b
substitute for a and c
(b-3)+b+(2b) = 53
reduce
4b-3 = 53
add 3 to each side
4b = 56
divide both sides by 4
b = 14
a = 14-2 = 11
c = 2(14) = 28

Khloe drove 204 miles in 4 hours. if she continued at the same rate, how long would it travel 765 miles?
Answer:
15
Step-by-step explanation:
A large bakery has many different products for sale. Suppose that 200 customers come in between 6 am and 10 am. Of the 200 customers, 140 order donuts, 100 order cinnamon rolls, and 80 order both. Suppose a customer is randomly selected. Find P(no donuts and no cinnamon rolls).
Out of 200 customers, the probability of a customer not ordering either donuts or cinnamon rolls is 0.2 or 20%.
Use the concept of probability defined as:
For the occurrence of an event, it is a ratio of the number of favorable outcomes to the number of total outcomes.
Given that,
Time frame: 6 am to 10 am
Total number of customers: 200
Number of customers who ordered donuts: 140
Number of customers who ordered cinnamon rolls: 100
Number of customers who ordered both donuts and cinnamon rolls: 80
To find the probability of a customer ordering neither donuts nor cinnamon rolls:
Subtract the probability of a customer ordering either donuts or cinnamon rolls or both from 1.
Now calculate:
Probability of ordering donuts:
140 out of 200 customers ordered donuts,
The probability of ordering donuts is,
140/200 = 0.7.
Probability of ordering cinnamon rolls:
100 out of 200 customers ordered cinnamon rolls,
The probability of ordering cinnamon rolls is,
100/200 = 0.5.
Probability of ordering both donuts and cinnamon rolls:
80 out of 200 customers ordered both,
The probability of ordering both is,
80/200 = 0.4.
Now, to find the probability of a customer ordering neither donuts nor cinnamon rolls,
Subtract the probability of ordering either or both from 1:
P(no donuts & no cinnamon rolls) = [tex]1 - P( \text{donuts}) - P(\text{cinnamon rolls}) + P(\text{donuts & cinnamon rolls})[/tex]
[tex]\text{P(no donuts & no cinnamon rolls)}= 1 - 0.7 - 0.5 + 0.4[/tex]
[tex]\text{P(no donuts & no cinnamon rolls)} = 0.2[/tex]
Hence,
The probability of a customer not ordering either donuts or cinnamon rolls is 0.2 or 20%.

can some one help me please what is %75 to $25
The answer you are looking for is .
To find this answer, you first make 75% into a decimal. To do so, simply divide 75 by 100 to get 0.75. Finally, you multiply 0.75 to 25. This will give you 1875 which you add a decimal point between the 8 and the 7, because .75 has 2 digits behind the decimal (as should the answer. Thus getting 18.75 as an answer. Here's an image to show the multiplication of 0.75 and 25.

Select all the points that are on the graph of the line 2x+4y=20.

F=(0,10)
Answer:
i am sure there is B and E

.
Answer:
(0,5) and (10,0)
Step-by-step explanation:
The equation of the straight line is given by 2x + 4y = 20 .......... (1)
Now, point (0,5) satisfies the equation (1) as putting x = 0, we will get y = 5.
Now, point (0,10) does not satisfy the equation (1) as putiing x = 0, we get y = 5 ≠ 10
Again, point (1,2) does not satisfy the equation (1) as putiing x = 1, we get y = 4.5 ≠ 2
Now, point (1,4) does not satisfy the equation (1) as putiing x = 1, we get y = 4.5 ≠ 4
Again, point (5,0) does not satisfy the equation (1) as putiing y = 0, we get x = 10 ≠ 5
Finally, point (10,0) satisfies the equation (1) as putiing y = 0, we get x = 10 .
Therefore, only points (0,5) and (10,0) are on the graph of the line 2x + 4y = 20 (Answer)

Answer:
b) 272/p
Step-by-step explanation:
1/4(px-16)=64
1. multiply 4 on both side to cancel out 1/4
(px-16)=256
2. move -16 to the otherside (making it postive)
px=16+256
px=272
3. divide by p on both sides
x=272/p
Nicki and june win some money and share it in the ratio 5:3 buck gets £26 more than june how much did june get
Answer:
£39
Step-by-step explanation:
Given data
The sharing formula is
5:3
Let June get £x
Buck gets £26 more than june
Buck = x+26
Applying the part to part ratio method
5/3= x+26/x
cross multiply
3(x+26)= 5x
3x+78= 5x
78= 5x-3x
78= 2x
x= 78/2
x= £39
Hence June get £39

You are selling candy bars. It cost $140 for
a startup fee and $1.50 per candy bar. Your
income is based on the fact that you are
selling the candy bars for $4.00 each.
1) What is the profit from selling 40 candy bars? The profit is $ ........
2) What is the profit selling 100 candy bars? The profit is $ .......
3) In order to break even you must sell .......... candy bars.
4) The minimum of candy bars you must sell in order to start making positive profit is .......... candy bars.
Answer:
Profit = price charged - cost of goods
$10 = Price - 30.00
$40 = Price of one box
So, they have to charge $40 per box. Since there are 50 bars in each box, the price per bar has to be:
$40.00/50 bars = $0.80 per bar
You can check this....
0.80 x 50 bars = $40.00 <<< this is the total income from the sale of one box.
since each box costs $30.00, they've made $10.00 on each box.

Answer:
a) Area of sector TRV = [tex] 42.4\: units^2 [/tex]
b) [tex] 0.8\: units[/tex]
Step-by-step explanation:
a)
In [tex] \odot R[/tex], TW is diameter.
Therefore,
[tex] m\widehat {TVW} = 180\degree [/tex]
[tex] \because m\widehat {TV} +m\widehat {VW} =m\widehat {TVW} [/tex]
[tex] \therefore m\widehat {TV} +120\degree =180\degree [/tex]
[tex] \therefore m\widehat {TV} =180\degree - 120\degree [/tex]
[tex] \therefore m\widehat {TV} = 60\degree [/tex]
[tex] \because m\angle TRV=m\widehat{TV} [/tex]
(Measure of central angle is equal to the measure of its corresponding arc)
[tex] \therefore m\angle TRV\:(\theta) =60\degree [/tex]
Radius (r) = RW = 9 units
Area of sector TRV
[tex] =\frac{\theta}{360\degree}\times \pi r^2 [/tex]
[tex] =\frac{60\degree}{360\degree} \times 3.14\times 9^2 [/tex]
[tex] =\frac{1}{6} \times 3.14\times 81 [/tex]
[tex] =\frac{1}{6} \times 254.34 [/tex]
[tex] =42.39\: units^2 [/tex]
Area of sector TRV[tex] =42.4\:units^2 [/tex]
b)
Length of [tex] \widehat{VW} [/tex]
[tex] =\frac{120\degree }{360\degree} \times 2\pi r [/tex]
[tex] =\frac{2}{3} \times 3.14\times 9 [/tex]
[tex] =2 \times 3.14\times 3 [/tex]
Length of [tex] \widehat{VW} [/tex] [tex] = 18.84\: units [/tex]
[tex] \overline{TW} =2*RW =2*9 = 18\: units[/tex]
[tex] \widehat{VW}- \overline{TW}= 18.84-18=0.84\: units[/tex]
[tex] \widehat{VW}- \overline{TW}= 0.8\: units[/tex]
