Answer:6.5

Step-by-step explanation:

Here j = 0.5 and k = 0.25

7j+5-8k

= 7(0.5)+5-8(0.25)

= 3.5+5-2

= 6.5

we know that [tex]r[/tex]

area of the circle is equal to

A=  [tex]\pi[/tex] × [tex]r^{2}[/tex]

solve for [tex]r[/tex]

[tex]r[/tex] = [tex]\sqrt{\frac{A}{\pi } }[/tex]

for A=60cm2

[tex]r[/tex] = [tex]\sqrt{\frac{60}{\pi } cm}[/tex]

we know that

[tex]\sqrt{60\\}[/tex] = [tex]\sqrt{2^{4} }[/tex] × 3 × 5

=2[tex]\sqrt{15}[/tex]

so,

[tex]\sqrt{\frac{60}{\pi } }[/tex] = 2 [tex]\sqrt{\frac{15}{\pi } }[/tex]

2[tex]\sqrt{\frac{15}{\pi } } = 2\frac{\sqrt{15} }{\pi }[/tex]  × [tex]\frac{\sqrt{\pi } }{\sqrt{\pi } }[/tex]

= 2 [tex]\frac{\sqrt{15\pi } }{\pi }[/tex]cm

this means the answer is-

2 [tex]\frac{\sqrt{15\pi } }{\pi } cm[/tex]

The smallest possible value of the sum of the eight integers is given by:

116.

The eight integers in the problem are given as follows:

n, ..., n + 7.

Hence:

The smallest integer is more than 3/5 of the largest integer, hence the following inequality is built to relate them:

n > 3/5(n + 7)

Applying the distributive property on the right side, we have that:

n > 0.6n + 4.2.

0.4n > 4.2

n > 4.2/0.4

n > 10.5.

Hence the integers are:

11, 12, 13, 14, 15, 16, 17, 18.

(as 11 is the smallest integer possible).

Then the value of the sum is obtained as follows:

11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 = 116.

Answer: 11 Cents per ounce of Juice

Step-by-step explanation:

The first step here is going to be to find how many ounces are in a gallon. This can be determined as shown using the given information you stated above:

1 gallon * 4 quarts * 2 pints * 2 cups * 8 ounces = 128 ounces in 1 gallon

Step 2 is multiplying 128 ounces by 2 because we have two gallons of juice in the bottle:

128 ounces per gallon* 2 gallons = 256 ounces

Step 3 is dividing the total cost of the juice, which is $28.16, by the number of total number ounces (256)

$28.16 / 256 ounces = .11 dollars per ounce (aka 11 cents per ounce)

Zeros of f(x) = [tex]x^{2} +6x[/tex] is (0,0) and (-6,0).

Given, f(x) = [tex]x^{2} +6x[/tex]

                = x(x+6)

For zeros, function f(x) = 0

x(x+6) = 0

x = 0    x+6 = 0

                x = -6

Putting values of x in equation,

For x = 0

f(x) = [tex]0^{2}+6(0)[/tex]

     = 0

Therefore, (0,0)

For x = -6

f(x) = [tex](-6)^{2}+6(-6)[/tex]

     = 36 - 36

     = 0

Therefore, (-6,0)

Hence, zeroes for f(x) is (0,0) and (-6,0).

The equation of a straight line can be written if its slope and any one point lying on it is given. The  equation of the line for given slope and point is  (y - 3) = -1 / 7 × (x - 3). The correct answer is option B.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

Given that,

The slope of the line = -1 / 7

The coordinate of the point on the line = (3,3)

The equation of a line having slope m and passing through a point (x₁, y₁) is given as,

(y - y₁) / (x - x₁) = m

Thus, the equation of the line for given slope and point is given as,

(y - 3) / (x - 3) = -1 / 7

=> (y - 3) = -1 / 7 × (x - 3)

Hence, the equation of the line for given slope and point is  (y - 3) = -1 / 7 × (x - 3).

The tons of waste recycled in 2021 was 619.4286 tons.

According to the question,

We have the following information:

In 2021: There were 2341 people living in the town. Each person in the town recycled an average of 264.6kg of waste. Aleks knows that 1 ton = 1000kg.

Now, the total waste recycled in 2021 can be found using multiplication:

Number of people*waste recycled by each person

2341*264.6

619428.6 kg

Now, we will convert this from kilogram to tons.

1 ton = 1000 kg

1 kg = 1/1000 ton

So, we will divide the waste in kilogram by 1000:

Total waste recycled = 619428.6/1000

Total waste recycled = 619.4286 tons

Hence, the tons of waste recycled in 2021 was 619.4286 tons.

Answer: t = 5d t = 1/5d

Step-by-step explanation:

The Linear function representing the total cost , where x is the number of tickets is  c(x) = 5. 50 + 20. 50x  , the correct option is (a) .

In the question ,

it is given that ,

the total cost for 5 tickets = $108

the service fees for the tickets to a basketball game = $5.50

we need to find the cost function for 5 tickets .

we substitute , the value of x = 5 in each option and check which option gives the cost as $108 .

Option (a)

c(x) = 5.50 + 20.50x

= 5.50 + 20.50(5)

= 108

Option(b)

c(x) = 5. 50x + 20. 50

= 5.50(5) + 20.50

= 48

Option(c)

c(x) = 5. 50 + 21. 60x

= 5.50 + 21.60(5)

= 113.5

Option(d)

c(x) = 5. 50x + 21. 60

= 5.50(5) + 21.60

= 49.1

So, from the answers above we can conclude that the cost function representing the cost for 5 tickets is c(x) = 5. 50 + 20. 50x   .

Therefore , The Linear function representing the total cost , where x is the number of tickets is  c(x) = 5.50 + 20.50x  .

The given question is incomplete , the complete question is

Tickets to a basketball game can be ordered online for a set price per ticket plus a $5.50 service fee. The total cost in dollars for ordering 5 tickets is $108 . Which linear function represents c, the total cost, when x tickets are ordered ?

(a) c(x) = 5.50 + 20.50x

(b) c(x) = 5.50x + 20.50

The formula that is used to calculate the midpoint for the given two point is written as ( (x₁ + x₂)/2 , (y₁ + y₂)/2).

Mid point:

Midpoint refers the point on a line that is at an equal distance from either end.

Given,

Here we have to explain the concept of midpoint in a simple manner.

According to the definition, midpoint refers the central point between the two points.

So, in a simple manner we have said that the mid point is calculated by finding the average of the two given point.

For example, (x₁, y₁) and (x₂, y₂) are the points, then the midpoint (xₙ, yₙ) is calculated by using the formula,

(xₙ, yₙ) = ( (x₁ + x₂)/2 , (y₁ + y₂)/2)

Similarly, if one point and the midpoint is given, then the another point is calculated by apply the remaining point as (x, y) and solve it accordingly, then we can get the value of it.

The simplified expression using the commutative property is in the first option :  1/3 + 2/3 + 3/5   = 1 + 3/5 = 1 3/5 .

now the given expression is 1/3 + 2/3 + 3/5 .

Therefore this expression can be simplified using the commutative property where we put the like terms together.

1/3 + 3/5  + 2/3

= 1/3 + 2/3 + 3/5 (here we use commutative property on the second and third terms of the expression)

= 1 + 3/5 (we know that 1/3 +2/3 = 1)

=1 3/5

Hence by using the commutative property we calculate the sum easily.

The commutative property applies to the arithmetic operations of addition and multiplication. This suggests that no matter how the numbers are arranged or placed, the result of adding or multiplying them remains the same.

As an illustration, 1 + 5 = 6 and 5 + 1 = 6. No matter how two numbers are added, the sum is unaffected. Multiplication uses the same principle. The commutative property does not hold for division and subtraction because the results are completely different when the numbers are rearranged.
