Answer:
22.91 inches
Step-by-step explanation:
circumference = 2πr
2πr = 72 inches
2 x [tex]\frac{22}{7}[/tex] x r = 72
[tex]\frac{44}{7}[/tex] x r = 72
Solving for r , divide both sides of the equation by 7/44
r = 11.454545 inches
diameter= 2 x radius
2 x 11.454545 inches = 22.91 inches

a second.
Are these two events dependent or independent?
Answer:
This is dependent because it depends what sock she picked out first. It would be independent if she put the pulled out sock back into the container
A school purchases a used van that costs $10,000. The value, V(t), in dollars, of the van t years since its purchase is modeled by the exponential function V(t)=10,000(0.8)^t . Select ALL statements that are true regarding the value of the van. a.The value of the van decreases by 20% each year since its purchase. b.The value of the van decreases by 80% each year since its purchase. c.The value of the van decreases by $2,000 each year since its purchase. d.Each year since its purchase, the value of the van is 80% of the value of the previous year. e.Each year since its purchase, the value of the van is 0.8 times the value of the previous year.
Answer:
a.The value of the van decreases by 20% each year since its purchase.
b.The value of the van decreases by 80% each year since its purchase.
d.Each year since its purchase, the value of the van is 80% of the value of the previous year.
Step-by-step explanation:
From the above question, we are given the Exponential function
V(t)=10,000(0.8)^t
Verifying the given options:
a.The value of the van decreases by 20% each year since its purchase.
Option a is correct , this is because, the Exponential function above is and Exponential Decrease.
The formula is given as:
V(t) = 10000(1 - r) ^t
Where r = Decreasing rate
Comparing
= 1 - r = 0.8
= 1 - 0.8 = r
r = 0.2
Converting to percentage
= 0.2 × 100 = 20%
Option a is correct
b.The value of the van decreases by 80% each year since its purchase.
Let solve for t = 1 and t = 2
V(t) = 10000(0.8) ^t
When t = 1
= 10000× 0.8¹
= 8000
When t = 2
= 10000× 0.8²
= 6400
Confirming option d
For year 2
= 80% × year 1
Year 1 = 8000
= 80% × 8000 = 6400
Option b is correct
c.The value of the van decreases by $2,000 each year since its purchase.
Option C is incorrect
d.Each year since its purchase, the value of the van is 80% of the value of the previous year.
Option d is correct because
Let solve for t = 1 and t = 2
V(t) = 10000(0.8) ^t
When t = 1
= 10000× 0.8¹
= 8000
When t = 2
= 10000× 0.8²
= 6400
Confirming option d
For year 2
= 80% × year 1
Year 1 = 8000
= 80% × 8000 = 6400
Option d is correct
e.Each year since its purchase, the value of the van is 0.8 times the value of the previous year.
Option e is incorrect
From the options given in the question, the correct statements are,
Options a, b, and d.

ASAp question in pic
Answer:
B and E
Step-by-step explanation:
They have different slopes so of course they will have to intersect at least 1 time. And if they were curved, it would be more than 1. But these are lines so it would be just 1 intersection. So B is one of the answers.
The solutions of the system are x = 0 and y = 2
I hope this helped, please mark me brainliest!
Step-by-step explanation:
y = 2x + 2 and y = 6x + 2
=> 2x + 2 = 6x + 2
=> 2x = 6x
=> 4x = 0, x = 0.
Therefore y = 2(0) + 2 = 2.
The point of intersection is (0, 2).
Hence there is exactly 1 point of intersection and exactly 1 real solution. (B and E)

and given we know that
[tex]\angle EAF = \angle EAD = 4x+6[/tex]
solving for x
we know that

The cost of a hamburger is $1.15 more than an order of large fries bill bought two hamburger ms and an order of large fries for a total of $8.60 what is the price of each item
Answer:
The cost of an order of large fries is [tex]\$ 2.10[/tex] and the cost of a hamburger is [tex]\$3.25[/tex].
Step-by-step explanation:
Let the cost of an order of large fries be [tex]\$ x[/tex].
Then, the cost of a hamburger is [tex]\$ x+\$1.15[/tex].
Bill bought two hamburgers and an order of large fries for a total of [tex]\$ 8.60[/tex].
So, [tex]2(x+1.15)+x=8.60[/tex]
[tex]\Rightarrow 2x+2.30+x=8.60[/tex]
[tex]\Rightarrow 3x=8.60-2.30[/tex]
[tex]\Rightarrow 3x=6.30[/tex]
[tex]\Rightarrow x=\frac{6.30}{3}[/tex]
[tex]\Rightarrow x=2.10[/tex]
So, the cost of an order of large fries is [tex]\$ 2.10[/tex].
And, the cost of a hamburger is [tex]\$2.10+\$1.15=\$3.25[/tex].
Hence, the cost of an order of large fries is [tex]\$ 2.10[/tex] and the cost of a hamburger is [tex]\$3.25[/tex].
Your factory installed tires have a comfort that 95 inches if the odometer reading reading is 32,000 miles on your car you have tires with a conference have 103 inches how many miles have you actually traveled
Answer:
The correct solution is "35440.8".
Step-by-step explanation:
The given values are:
Bigger tire's circumference,
= 103 inches
Factor installed tire's circumference,
= 95 inches
Odometer reading,
= 32,000 miles
As we know,
⇒ [tex]Actual \ distance = K\times odometer \ reading[/tex]
Where,
⇒ [tex]K = \frac{Bigger \ tier \ circumference}{Factor \ installed \ tier \ circumference}[/tex]
i.e.,
⇒ [tex]K=\frac{103}{95}[/tex]
On applying the formula,
⇒ [tex]Actual \ distance \ travelled=\frac{103}{93}\times 32,000[/tex]
⇒ [tex]=35440.8[/tex]

On a long hike, Greg forgets to fill his canteen. Fortunately, Harold has 40 ounces of water and jake has 60 ounces. The three hikers share water so that each gets an equal amount. At the end of the hike, Greg gives Harold and Jake $5 to split for the water they gave him. How much should Harold and Jake get?
Answer:
Jake should get $3 because he would have given more water since he had the most out of all of them. Harold should get $2 because he gave less water
Step-by-step explanation:
The amount that Harold and Jake will get is $2 and $3, respectively.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Harold has 40 ounces of water, which is needed to be shared among the three, therefore, the amount of water that each of the three will get is,
Amount of water = Total water / Number of persons
= 40 ounces of water / 3 person
= (40/3) ounces per person
Thus, Greg will get (40/3) ounces of water from Harold.
Similarly, Jake has 60 ounces of water, which is needed to be shared among the three, therefore, the amount of water that each of the three will get is,
Amount of water = Total water / Number of persons
= 60 ounces of water / 3 person
= (60/3) ounces per person
Thus, Greg will get (60/3) ounces of water from Harold.
Further, Harold and Jake will get the money in the ratio of the amount of water they shared, therefore, we can write,
(40/3)x + (60/3)x = $5
(40x + 60x)/3 = 5
100x = 5 × 3
x = 15/100
Furthermore, the money each of two will get is,
Amount that Harold will get,
(40/3)x
= (40/3) × (15/100)
= $2
Amount that Jake will get,
(60/3)x
= (60/3) × (15/100)
= $3
Hence, the amount that Harold and Jake will get is $2 and $3, respectively.

Convert 0.263 repeating (the 63 are repeating) into a fraction.
Answer:
[tex]\frac{29}{110}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating 63 placed after the decimal point
let x = 0.2636363.... ( multiply both sides by 10 and 1000 )
10x = 2.6363... → (1)
1000x = 263.6363.... → (2)
Subtracting (1) from (2) eliminates the repeating value, that is
990x = 261 ( divide both sides by 990 )
x = [tex]\frac{261}{990}[/tex] = [tex]\frac{29}{110}[/tex] ← in simplest form
The number n = 0.263 as a fraction is A = 263/999
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the number be represented as n = 0.263
Now , the Let x = 0.263636363 repeating
Multiply both sides by 1000 to move the decimal point to the right:
1000x = 263.636363 repeating
Subtract x from both sides:
999x = 263
Divide both sides by 999:
x = 263/999
Hence , 0.263636363 repeating is equivalent to the fraction 263/999
