E. 8t + 16 is equivalent to 8t + 16

F. (8 + t) + (8 + 8) is equivalent to 16 + t.

So the expressions that are equivalent to 8(t + 8) are B and C, the expression that is equivalent to 8t + 8 is E, and the expression that is neither is F.

In the given problem, we are comparing the given expressions to see if they are equivalent to 8(t + 8), 8t + 8, or neither.

Expression A: (8 * t) + (8 * 8) = 8t + 64

This expression is equivalent to 8t + 64, which is not the same as 8(t + 8) or 8t + 8.

Expression B: 4t + 8 + 4t = 8t + 8

This expression is equivalent to 8t + 8, which means that adding up 4t and 8, and then adding 4t again to the result is the same as multiplying 8 with t and adding 8 to the result.

Expression C: 4(2t + 2) = 8t + 8

This expression is also equivalent to 8t + 8, which means that multiplying 2t + 2 with 4 is the same as multiplying 8 with t and adding 8 to the result.

Expression D: 8t + 64 = 8t + 64

This expression is the same as 8t + 64, which is not equivalent to either 8(t + 8) or 8t + 8.

Seraphina's speed has increased by a factor of around 23% compared to the first hour.

What Is a Change in Percentage?

The ratio of the difference in the amount to its starting value multiplied by 100 is known as the percentage change. When a number's final value is determined by increasing or decreasing a percentage of its starting value, the percentage change of that quantity will always change.

How can you determine the percentage to the closest tenth?

Rounding to the closest tenth entails adding one integer after the decimal point. The number in the thousandths place, or the second number from the right of the decimal, must be considered while rounding. If the amount is five or more, we add one percent to the number in the tenth position.

Percent Change Formula = [tex]\frac{ (Final value -Initial value)}{ (Initial value)}[/tex]× 100

Percent Change               = [tex]\frac{(74-60)}{60}[/tex]× 100

…                                     = [tex]\frac{14}{60}[/tex] × 100

...                                     ≈ 0.23333 × 100

Percent Change             ≈ 23.33%

The diameter of the pizza to the nearest inch is 11 inches.

Let's call the diameter of the pizza "d". The circumference of the pizza can be calculated using the formula:

C = πd

And since the outer edge of the crust from one piece measures 5.5 inches, that length is equal to 1/8 of the circumference of the pizza:

5.5 = (1/8)C

So we can substitute the formula for the circumference into this equation:

5.5 = (1/8)(πd)

Solving for d, we can multiply both sides by 8/π:

d = (5.5)(8/π)

Calculating the approximate value of π as 3.14, we get:

d ≈ (5.5)(8/3.14) = 11 inches

So the diameter of the pizza is approximately 11 inches, rounded to the nearest inch.

For question 3, Isabella needs 5/4 of a gallon of the food to make 5 gallons of the mixture.

Answer:

f(n) = 10 + 3n

Step-by-step explanation:

Each of the expressions has 10 + a certain number of 3's

For example for n = 3 we have
f(3) = 10 + 3 threes = 10 + 3 x 3 = 10 + 9 = 19

For n = 4, we have

f(4) = 10 + 4 threes = 10 + 4 x 3 = 10 + 12 = 22

The others follow the same pattern

So the explicit equation is

f(n) = 10 + 3n

Testing on n = 6 we get

f(6) = 10 + 6n = 10 + 6 x 3 = 10 + 18 = 28

Answer:

Step-by-step explanation:

[tex]\mathrm{3 (x - 10) = 63}[/tex]

Answer: 0.46.

Step-by-step explanation:

The probability that a randomly selected can of food will be corn is equal to the fraction of cans that are corn, out of the total number of cans.

Since 46 out of 100 people brought a can of corn, we can assume that there were 46 cans of corn donated. We do not know how many total cans were donated, but we can find out by using the fact that each person was required to bring one can of food. Therefore, the total number of cans donated is equal to the total number of people who attended the dance, which is 100.

So, the probability of selecting a can of corn is:

P(corn) = Number of cans of corn / Total number of cans

P(corn) = 46 / 100

Simplifying the fraction, we get:

P(corn) = 23 / 50

Therefore, the probability that a randomly selected can of food will be corn is 23/50 or approximately 0.46.

Answer: Child ticket: $8, Adult ticket: $6

Step-by-step explanation:

Let's call the price of 1 adult ticket "a" and the price of 1 child ticket "c".

On the first day, the school sold 3 adult tickets for a total of 3a dollars, and 2 child tickets for a total of 2c dollars, for a total of 34 dollars. So, we have the equations:

3a + 2c = 34

On the second day, the school sold 3 adult tickets for a total of 3a dollars and 12 child tickets for a total of 12c dollars, for a total of 114 dollars. So, we have another equation:

3a + 12c = 114

We can now use these two equations to solve for the value of "a" and "c".

We can use substitution to solve for one variable, then substitute it back into either of the equations to solve for the other variable.

Let's solve for "a" by substituting the first equation into the second:

3a + 12c = 114

3a = 114 - 12c

a = (114 - 12c) / 3

Now that we have an equation for "a", we can substitute it back into the first equation to solve for "c":

3a + 2c = 34

3[(114 - 12c) / 3] + 2c = 34

114 - 12c + 2c = 34

-10c = -80

c = $8

So, the price of 1 adult ticket is

a = (114 - 12c) / 3

a = (114 - 12 * 8) / 3

a = (114 - 96) / 3

a = 18 / 3 = $6.

A triangle represents 1/4 of the trapezoid, a diamond represents 1/2 of the trapezoid, and a hexagon represents 1/1 of the trapezoid.

Each shape represents a different part of the overall trapezoid.

The triangle represents 1/4 of the full trapezoid. This is because the trapezoid has four triangles, all of the same size. So each triangle is 1/4 of the whole trapezoid. The diamond represents 1/2 of the full trapezoid. This is because the trapezoid has two diamonds, each of the same size. So each rhombus is 1/2 of the whole trapezoid.

The hexagon represents 1/1 of the whole trapezoid. This is because the trapezoid has only one hexagon, which is the same size as the entire trapezoid. So the hexagon is 1/1, the whole trapezoid.

In summary, a triangle represents 1/4 of a trapezoid, a diamond represents 1/2 of a trapezoid, and a hexagon represents 1/1 of a hexagon. Using these fractions, we can determine the value of each shape relative to the overall trapezoid.

59 is a prime number.

This means that it cannot be divided evenly by any other number except for 1 and itself. A composite number, on the other hand, can be divided evenly by at least one other number besides 1 and itself.

To determine if a number is prime or composite, you can use a simple test. Start by dividing the number by 2. If the result is a whole number, then the number is composite.

If the result is not a whole number, try dividing by 3, 4, 5, and so on until you find a whole number result or until you reach the square root of the original number. If you reach the square root without finding a whole number result, then the number is prime.

For example, with the number 59:

59 / 2 = 29.5 (not a whole number)
59 / 3 = 19.67 (not a whole number)
59 / 4 = 14.75 (not a whole number)
59 / 5 = 11.8 (not a whole number)
59 / 6 = 9.83 (not a whole number)
59 / 7 = 8.43 (not a whole number)
59 / 8 = 7.38 (not a whole number)

Since we have reached the square root of 59 without finding a whole number result, we can conclude that 59 is a prime number.
