the proportional relationship?
The proportional relationship that models this situation is given by:
y = 16.99x, 0 ≤ x ≤ 12.
What is a direct proportional relationship?In a direct proportional relationship, the output variable y is found as the multiplication as the multiplication of the constant k by the input variable x, according to the following rule:
y = kx
In the context of this problem, the input variable and the output variable are given as follows:
x: number of months.y: total cost of the plan during x months.The monthly cost for the first 12 months is of $16.99, hence the constant is given as follows:
k = 16.99.
Considering the given domain, the relationship is modeled by the following equation:
y = 16.99x, 0 ≤ x ≤ 12.
What is the missing information?The missing information is that for the first 12 months, the monthly cost of the plan is of $16.99.

The value of x is approximately 5.4 when x^3 -10x = 100
How to solve the equation?
The equation is given as:
x^3 -10x = 100
Using trial by error, we keep testing for the value of x that is true for x^3 -10x = 100
After several attempts, we have:
x = 5.4 (approximately)
Substitute 5.4 for x in x^3 -10x = 100
5.4^3 -10 * 5.4 = 100
Evaluate
103.5 = 100
Approximate
100 = 100This means that x is approximately 5.4 when x^3 -10x = 100

Which could be the first step in solving the equation represented by the model below? XX X X Add 4 negative unit tiles to both sides. Add 4 negative unit tiles to the left side, and add 6 negative unit tiles to the right side. Add 4 positive unit tiles to both sides. Add 6 negative unit tiles to the left side, and add 4 negative unit tiles to the right side.
The most appropriate choice for linear equation will be given by -
First option is the correct option
Adding 4 units negative tiles to both sides.
What is linear equation?
Equation shows the equality between two algebraic expressions by connecting the two algebraic expression by an equal to sign.
A one degree equation is called linear equation.
Here,
The equation is 3x + 4 = 2x + 6
For the second option,
If we have to add 4 units negative tiles to left side, we will also have to add 4 units negative tiles to right side.
Second option is wrong
For the third option
We have to add four units negative tiles to both sides, not 4 units positive tiles.
For the fourth option
Adding 6 units negative tiles to left side and 4 units negative tiles to right side will not eliminate any of 6 or 4.

She walks a distance of 13.45 meters from the goalpost, then places a mirror on flat on the ground, marked with an X at the center. She then steps 1.2 meters to the other side of the mirror, until she can see the top of the goalpost clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.35 meters. How tall is the goalpost? Round your answer to the nearest hundredth of a meter.
The goalpost is 15.13 meters tall which is labeled as X in the figure which has been attached below.
She walks 13.45 meters away from the goalpost, then places a mirror flat on the ground with an X in the center. She next walks 1.2 meters to the opposite side of the mirror, where she can easily see the top of the goalpost depicted in the X. Her partner determines that the distance between her eyes and the ground is 1.35 meters.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
As per the given information, the figure has been attached below.
Set up the proportional and solve for x
1.2 : 13.45 = 1.35 : x
⇒ 1.2 / 13.45 = 1.35 / x
Cross multiplication, and we get
⇒ 1.2x = 1.35 × 13.45
Divided by 1.2 into both sides of the above equation,
⇒ x = (1.35 × 13.45) / 1.2
⇒ x = 15.13
Therefore, the goalpost is 15.13 meters tall.

a population of watermelons in a farmer’s field has unknown population mean weight , but the population standard deviation weight is known to be about
95% confidence interval for the true population mean watermelon weight. is (69.94, 72.06)
Confidence Interval formula = Mean ± z × Standard deviation/√n
Mean = 71 ounces
Standard deviation = 2.8 ounces
z score = 95% confidence interval = 1.96
Confidence Interval = 71 ± 1.96 × 2.8/√27
= 71 ± 1.96 × 0.5388602512
= 71 ± 1.0561660924
71 - 1.0561660924
= 69.943833908 ounces
Approximately = 69.94 ounces
71 + 1.0561660924
= 72.0561660924 ounces
Approximately = 72.06 ounces
95% Confidence Interval = (69.94, 72.06).

a fruit salad contains pineapples, apples. bananas, and oranges. It contains twice as many bananas as apples, 10 times as many oranges as pineapples, and the same number of apples as oranges. Jeff made this fruit salad using 1 pineapple. How many of each of the other fruits did he use
Using algebraic expression, if Jeff made the fruit salad using one pineapple, then he use 10 oranges, 10 apples and 20 bananas
Number of pineapples = 1 pineapple
Number oranges equal to the 10 times the number of pineapples
We have to multiply number of pineapples by 10
Number of oranges = 1×10
= 10 oranges
Number of oranges equal to the number of apples
Number of apples = 10 apples
Number of bananas equal to the twice the number of apples
Number of bananas = 2×10
= 20 bananas
Hence, using algebraic expression, if Jeff made the fruit salad using one pineapple, then he use 10 oranges, 10 apples and 20 bananas

The square root of a certain number is approximately 9.2371. The certain number is between what 2 integers
The number square root of which is 9.2371 is equal to 85.32 and it lies between two integers which are 81 and 100.
What is an integer ?
Integer is the collection of whole numbers and negative numbers. It does not include the fractional part.
It is given that square root of a decimal number is 9.2371 and we have to find out that the number lies between which 2 integers.
We know that the integer 9 is less than 9.2371 , so the square of 9 will be :
9² = 81
And
The square of next integer 10 is equal to 100.
The square of 9.2371 will be equal to :
= (9.2371)²
= 85.32
So , the number is 85.32 and it lies between 2 integers which are 81 and 100.
Therefore , the number square root of which is 9.2371 is equal to 85.32 and it lies between two integers which are 81 and 100.

A pile of sand has a weight of 65 kg.
Some of the sand is put into a small sack.
The rest of the sand is put into a large sack.
The sand in the large sack weighs 15 kg more than the sand in the small sack.
What is the weight of the sand in the small sack?
Answer:
25 kg
Step-by-step explanation:
The sum of the weights of the small and large sacks is 65 kg. The larger sack weighs 15 kg more. You want the weight of the smaller sack.
SetupLet w represent the weight of the sand in the small sack. Then (w+15) is the weight of the sand in the larger sack. The total weight is 65 kg, so we have ...
w +(w+15) = 65
SolutionSubtracting 15 from both sides gives ...
2w = 50
w = 25
The weight of the sand in the small sack is 25 kg.

Step-by-step explanation:
slope = rise/run = (difference in y)/(difference in x)
First, we find a difference in y.
Subtract any two values of y.
For example: 35 - 14 = 21
Now we find the corresponding difference in x.
Now subtract the x values corresponding to those y values in the same order.
-1 in x corresponds to 35 in y.
-4 in x corresponds to 14 in y.
That means your difference in x is the subtraction -1 - (-4) = -1 + 4 = 3
The difference in y is 21.
The difference in x is 3.
slope = (difference in y)/(difference in x) = 21/3 = 7
Answer: 7
