Answer: = 11.88
This is a 3 step / 4 show workings.
10.7 + Percentage increase = 11%
10.7 + (11% × 10.7) = 10.7 + 11% × 10.7
(1 + 11%) × 10.7 = (100% + 11%) × 10.7
111% × 10.7 = 111 ÷ 100 × 10.7
111 × 10.7 ÷ 100 = 1,187.7 ÷ 100
11.877 ≈ 11.88

If r = 4 and ^a8 = 100, what is the first term of the geometric
sequence?
The first term of the geometric sequence is 0.0061
Step-by-step explanation:
The general form of geometric sequence is a, ar, ar²,ar³,.......
where,
a is the first term of the sequence.r is the common ratio. Here, the common ratio r = 4.The 8th term of the sequence is 100. Hence n = 8.The formula to find the nth term of the geometric sequence is given by :
⇒ [tex]n_{th} term = ar^{n-1}[/tex]
⇒ [tex]8_{th}term = a\times4^{8-1}[/tex]
⇒ [tex]100 = a \times 4^{7}[/tex]
⇒ [tex]100 = a \times 16384[/tex]
⇒ [tex]a = \frac{100}{16384}[/tex]
⇒ a = 0.0061
Therefore, the first term of the geometric sequence is 0.0061
Answer:
The first term of the geometric sequence is 0.0061
John and Sarah are each saving money for a car. The total amount of money John will save is given by the function j(x)= x^2 +2x, where x represents the number of weeks. The total amount of money Sarah will save is given by the function s(x)= -3x+6, where x represents the numbers of weeks.
Explain the point of intersection in context to the problem. Show all work
Answer:
See below.
Step-by-step explanation:
Where the graphs of the functions intersect it represents the number of weeks when they have both saved the same amount of money. So by solving the system we can find the number of weeks and that amount of money.
y = x^2 + 2x
y = -3x + 6 so
x^2 + 2x = -3x + 6
x^2 + 5x - 6 = 0
(x + 6)(x - 1) = 0
So x = 1 ( we ignore the negative)
So after 1 week they have saved the same amount and the amount is -3 + 6 = 3.
Are you sure that -3x + 6 is right - because Sarah does not save anything after year 1 . The equation has a negative slope!!

A touch tank has a height of 3 feet. Its length is three
times the width. The volume of the tank is 270 cubic feet.
Find the length and width of the tank,
3 ft
Answer:
5.5 cu ft vol = L*w*h* w=x L= 3x h=3
270= 3[3x*x]
Final answer:
To find the length and width of the touch tank, we need to use the formula for the volume of a rectangular tank. By substituting the given values and solving the equation, we can find the width and length.
Explanation:
Let's assume that the width of the touch tank is x feet. So, the length of the tank would be 3x feet.
The volume of a rectangular tank is given by the formula volume = length × width × height. We can substitute the given values into this formula.
270 = (3x) * x * 3
Simplifying the equation, we get:
270 = 9x^2
Dividing both sides of the equation by 9:
x^2 = 30
Taking the square root of both sides of the equation:
x = √30 ≈ 5.48
Therefore, the width of the touch tank is approximately 5.48 feet. Since the length is three times the width, the length would be approximately 3 × 5.48 = 16.44 feet.

The cost to enter a waterpark increases from $56 per person to $73 per person. What percent of the entry fee increase
Final answer:
The percent increase of the waterpark's entry fee is approximately 30.36%, which is calculated by finding the difference between the new and original cost, dividing by the original cost, and then converting that number to a percentage.
Explanation:
To calculate the percent increase of the entry fee to the waterpark, we need to follow these steps:
Find the amount of the increase by subtracting the original cost from the new cost.Divide the amount of the increase by the original cost.Multiply the result by 100 to convert it to a percentage.Step 1: The increase in cost is $73 - $56 = $17 per person.
Step 2: The increase divided by the original cost is $17 ÷ $56 ≈ 0.30357.
Step 3: To find the percent increase, we multiply the result from step 2 by 100: 0.30357 × 100 ≈ 30.36%.
Therefore, the percent increase of the entry fee is approximately 30.36%.
To find the percent increase in the entry fee, subtract the old fee from the new fee, divide by the old fee, and multiply by 100. The entry fee increase is approximately 30.36%.
Explanation:To find the percent increase in the entry fee, you need to calculate the difference between the new fee and the old fee, and then divide that difference by the old fee. Finally, multiply the result by 100 to get the percentage.
Find the difference in the fees: $73 - $56 = $17Divide the difference by the old fee: $17 ÷ $56 ≈ 0.3036Multiply the result by 100 to get the percentage: 0.3036 × 100 ≈ 30.36%The entry fee increase is approximately 30.36%.

There are 870 boys and 800 girls in a school.
The probability that a boy chosen at random studies Spanish is 2/3
The probability that a girl chosen at random studies Spanish is 3/5
a) Work out the number of students in the school who study Spanish.
b) What is the probability, as a fraction in its simplest form, that a student
chosen at random from the whole school does not study Spanish?
Answer: a) 1060, b) [tex]\dfrac{61}{167}[/tex]
Step-by-step explanation:
Since we have given that
Number of boys = 870
Number of girls = 800
Probability that a boy chosen studies Spanish = [tex]\dfrac{2}{3}[/tex]
Probability that a girl chosen studies Spanish = [tex]\dfrac{3}{5}[/tex]
So, the number of boys in the school who study Spanish would be
[tex]\dfrac{2}{3}\times 870=290\times 2=580[/tex]
So, the number of girls in the school who study Spanish would be
[tex]\dfrac{3}{5}\times 800\\\\=3\times 160\\\\=480[/tex]
So, total number of students who study Spanish would be :
[tex]480+580=1060[/tex]
b) What is the probability, as a fraction in its simplest form, that a student
chosen at random from the whole school does not study Spanish?
Number of students who do not study Spanish would be:
[tex](870+800)-1060\\\\=1670-1060\\\\=610[/tex]
So, the probability of students who does not study Spanish would be :
[tex]\dfrac{610}{1670}=\dfrac{61}{167}[/tex]
Hence, a) 1060, b) [tex]\dfrac{61}{167}[/tex]
There are 1060 students who study Spanish in the school. The probability that a student chosen at random from the whole school does not study Spanish is 610/1670.
Explanation:To work out the number of students in the school who study Spanish, we need to find the number of boys and girls who study Spanish and add them together. The probability that a boy chosen at random studies Spanish is 2/3. So the number of boys who study Spanish is 870 * (2/3) = 580. The probability that a girl chosen at random studies Spanish is 3/5. So the number of girls who study Spanish is 800 * (3/5) = 480. Therefore, the total number of students who study Spanish is 580 + 480 = 1060.
To find the probability that a student chosen at random from the whole school does not study Spanish, we subtract the probability that a student does study Spanish from 1. The probability that a student does study Spanish is 1060 (students who study Spanish) divided by 1670 (total number of students in the school). Therefore, the probability that a student does not study Spanish is 1 - (1060/1670) = 610/1670, which is already in its simplest form.

surveyed, 30 said they could drive. Micah concluded that
knowing that a person is in college means they are more
likely to drive. Is Micah's conclusion correct?
Answer:
No
Step-by-step explanation:
this is because only 50% of the college students said they could drive there fore it doesn't make sense.
Answer:No, Micah is not correct. Since there are equal numbers in the group that drive and the group that doesn’t drive, the relative frequency for each is 50%. Because the relative frequencies are the same, there is no association between the variables.

Just square all of them to find 64
The square roots of 64 are -8 and 8. Neither 32 nor 64 1/2 are square roots of 64.
Explanation:The square root of a number is a value that, when multiplied by itself, gives the original number. When dealing with real numbers, remember that a number can have two square roots: a positive root and a negative root.
For the number 64, we know 8 * 8 equals 64, so 8 is a square root. As a negative number multiplied by a negative number results in a positive number, -8 * -8 also equals 64. Therefore -8 is also a square root of 64.

step 2:find x by dividing
220=27.50x
x=8
hope this helps,mark me brainliest.
There are 8 people who attended the park.
To solve the problem, let's define the variables and write an equation. Let x be the number of people who attended. The total cost is the sum of the parking fee plus the admission fees.
The parking fee is $8.50, and the admission fee per person is $27.50. Therefore, the total cost can be expressed as:
Total Cost = Parking Fee + (Admission Fee per Person * Number of People)
This simplifies to:
$228.50 = $8.50 + $27.50 * x
First, subtract the parking fee from the total cost:
$228.50 - $8.50 = $27.50 * x
$220 = $27.50 * x
Now, divide both sides by the admission fee per person to find x:
x = $220 / $27.50
x = 8
Thus, 8 people attended the park.
