Answer:
The required expression for the depth is [tex]5.5t[/tex] feet.
The depth after 1.3 minutes is 71.5 feet.
Step-by-step explanation:
Let d be the depth of the sea below the surface of the water.
The rate of descending or the rate of increasing the depth, [tex]r= 5.5[/tex] feet/min.
Since, the rate is constant, so,
If the diver reaches the depth, [tex]d[/tex], in time, [tex]t[/tex]. So,
[tex]r= d/t[/tex]
[tex]\Rightarrow d=r\times t[/tex]
So, for [tex]r=5.5[/tex] feet/min, the required expression for the depth is [tex]5.5t[/tex] feet.
After time t= 1.3 minutes.
The depth, [tex]d = 5.5 \times 1.3 = 71.5[/tex] feet.

Benito drew a graph representing the number of miles he ran and the number
calories he burned. What is the unit rate in calories per mile? 3 4 250 1,000
Answer:
250
Step-by-step explanation:
1000 divided by 4, is 250
The unit rate would be 250 calories per mile which is the slope of the given linear function.
What is the unit rate?The unit rate of a linear function is defined as the slope of the linear function.
The slope is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
The given graph represents the number of miles he ran and the number of calories burned.
Taking two points as per the given graph :(2, 500), (6, 1500)
Let
x₁ = 2, y₁ = 500
x₂ = 6, y₂ = 1500
Substitute values in the formula to get
unit rate = (1500 - 500)/(6 - 2)
unit rate = (1000)/(4)
Apply the division operation,
unit rate = 250
Therefore, the unit rate would be 250 calories per mile

Answer:
The answer would be 1.33 x [tex]10^{4}[/tex]
Step-by-step
1.28 x [tex]10^{4}[/tex] = 12800
5 x [tex]10^{2}[/tex] = 500
12800 + 500 = 13300
13300 = 1.33 x [tex]10^{4}[/tex] in scientific notation

Answer:217
Step-by-step explanation:
A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet away from the player. The height $y$y (in feet) of a second hockey puck is modeled by $y=x\left(0.15-0.001x\right)$y=x(0.15−0.001x) , where x$x$x is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.
Answer:
The maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels further
Also the distance of the maximum height of first pluck from the player is less than the distance of the second pluck from the player hence the second pluck travels further
Step-by-step explanation:
From the question we are told that
The maximum height of the first pluck is [tex]h_1 = 3 \ ft[/tex]
The height of the second height is mathematically represented as
[tex]$y=x\left(0.15-0.001x\right)[/tex]
=> [tex]y=0.15x -0.001x^2[/tex]
Generally at maximum height [tex]y' = 0[/tex]
So
[tex]y'=0.15 -0.002 x = 0[/tex]
=> [tex]x = 75 \ ft [/tex]
Here 75 ft is the horizontal distance the second pluck traveled at maximum height
So the maximum height of the second pluck is mathematically represented as
[tex]y=0.15(75) -0.001(75)^2[/tex]
=> [tex]y= 5.625 \ ft [/tex]
So comparing the maximum height of the first and the second pluck we see that the maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels father
A shipping company specializing in big items, like couches and cars, charges a $99 handling fee plus $0.32 per pound. Write an equation representing the total cost to ship an item based on its weight.
Answer:
$0.32x + $99 = c (cost)
Step-by-step explanation:
First, the problem tells you that the company is charging $0.32 per pound. The phrase "per pound" tells us that the 32 cents is not a fixed amount, so it must be paired with a variable like x since any item could easily weigh more than one pound when shipping.
Next, the problem says there's a handling fee of $99 for each purchase. This is a fixed amount, meaning there will be no variable with it since this fee will always just cost $99. This fee will be added to the $0.32x, so it can be represented anywhere in the equation like "+ $99" or "$99 +".
Finally, just write each term as an equation and you're all set! There can be multiple ways to write the equation. For example, $0.32x + $99 = c is correct, but $99 + $0.32x = c is also correct!
Pattie's Produce charges $2.29 for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 less packages will be sold each day. Let x represent the number of 20-cent increases in the cost of a package of strawberries.
Answer:
-1.8x² - 1.61x - 37.45 > 0
Step-by-step explanation:
Pattie's Produce charges $2.29 for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 less packages will be sold each day. Let x represent the number of 20-cent increases in the cost of a package of strawberries. Which inequality represents the values of x that would allow Pattie's Produce to have a daily revenue of at least $255 from selling the packages of strawberries?
Answer:
The cost of packaging 95 packages of strawberries is $2.29(95)=$217.55.
20-cent increase in the cost of a package of strawberries leads to 9 less packages to be sold. If x represent the number of 20-cent increases in the cost of a package of strawberries. the cost of packaging is:
Cost = (2.29 + 0.2x)(95 - 9x)
For a revenue of atleast $255:
(2.29 + 0.2x)(95 - 9x) > 255
217.55 - 20.61x + 19x - 1.8x² > 255
-1.8x² - 1.61x + 217.55 > 255
-1.8x² - 1.61x + 217.55 - 255 > 0
-1.8x² - 1.61x - 37.45 > 0

Find the GCF of 29 and 18
Answer:
1
Step-by-step explanation:
The greatest common factor of two numbers is the largest number that both can divide into.
29 is a prime number. This means that it is only divisible by 1 and itself.
18 has the factors 1,2,3,6,9,18.
Only the number 1 is a shared factor between the two numbers, therefore 1 is the greatest common factor of 29 and 18.
Hope this helped!
Answer:
1
Step-by-step explanation:
29 is a prime number. Hence, the GCM of a number x and 29 is 1 if x isn't divisible by 29. Because 18 isn't divisble by 29, the GCM of 18 and 29 is 1.
Hopefully this answer helps you :)

Answer: [tex]13.046< \overline{x}<22.15[/tex]
Step-by-step explanation:
Let x be the random variable that represents the data speed.
Given, Confidence interval for population mean : (13.046, 22.15)
Let [tex]\overline{x}[/tex] be the sample mean.
We need to write the confidence interval in "less than" format.

Mike hosted a fundraiser to benefit the children's hospital and the cancer society twenty people came and each paid 30 to enter the event an additional 800 was raised before the event
A) write a number expression to represent the total amount of money raised. Find the value of your expression.
B) mike split the money equally between the two organizations. How much did each organization receive?
PLEASE HELPPP
Answer:
Step-by-step explanation:
We know 20 people attended and each paid $30. There was already $800 before the event.
A)
T = total amount raised
p = number of people that attended
T = 30p + 800 $30 multiplied by the number of people who attended
T = 30(20) + 800 gives the amount raised at the fundraiser. We add 800
T = 600 + 800 because that was raised before the event.
T = $1400
B) If he split the money equaly between 2 organizations, we divide the total raised, T, by 2.
$1400/2 = $700 Each organization recieved $700

Jill is baking a pumpkin pie. The recipe calls for 4 ⅓ cups of flour, but Jill has 2 ⅘ cups. How many cups of flour does Jill need?
Answer:
1 8/15
Step-by-step explanation:
We need to equal the denominators. We have 1/3 and 4/5, and we need to make the bottom numbers equal to each other. The closest common factor is 15 (which we got from 3 x 5). With the denominators solved, we now need to equal out the top numbers, or the numerators. 1 x 5 gives us 5/15, and 4 x 3 gives us 12/15. Then, we need to apply these to each variable. This gives us Jill's 2 12/15th cups of flour, and the recipe's call for 4 5/15 cups. We then subtract these from each other, giving us 1 8/15 cups of flour is needed from Jill.

For extra info Angle C = 33.690067525979785.
They add up to 90 which added with the right angle of 90 means the interior angles add to 180 meaning it is in fact correct because a triangle is always 180 inside.
