Answer: 30 feet per second
========================================
x = diameter, y = speed of water
y varies inversely with respect to x, so, y = k/x for some constant k
If x = 0.6 and y = 5 pair up, then y = k/x turns into 5 = k/0.6 which solves to k = 3 when you multiply both sides by 0.6
So the equation y = k/x turns into y = 3/x
Now plug in the diameter x = 0.1 to find the speed to be...
y = 3/x
y = 3/0.1
y = 30 feet per second

Please Fill in the Blank with the simplified equation. 1/7r=10
Multiply both sides by 7
1/7 r ×7 = 10 ×7
7r/7 = 70
r = 70
Multiply both sides by 7
1/7 r ×7 = 10 ×7
1r = 70
Divide by 1 on both sides (Side by Side need to divide)
r = 70

Missy ordered french toast and she plans to leave a $7.00 tip to cover everyone. If she pays with a $20.00 bill, how much change should she receive? help asap
She will receive $13.00 change back,
hope i helped
Missy should receive $0.00 in change.
Explanation:To determine the change Missy should receive, we need to subtract the total amount she plans to pay from the cost of her food and the tip. If Missy's french toast costs $13.00 and she plans to leave a $7.00 tip, the total amount she plans to pay is $13.00 + $7.00 = $20.00. Since she pays with a $20.00 bill, the change she should receive is $20.00 - $20.00 = $0.00.

Next, subtract by seven-p from both sides of equation form.

The function C(t) below relates outside temperature in degrees Fahrenheit to the number of cricket chirps per minute. It takes as input the temperature in degrees Fahrenheit, and returns as output the number of cricket chirps per minute occurring at that time. C(t) = 6t - 180 Which equation below represents the inverse function T(c), which takes the cricket chirps per minute as input and returns as output the temperature in degrees Fahrenheit? A. B. C. D.
Step-by-step explanation:
I had a different A pex question but it was still relatively the same answer but i don't want anyone getting the answer wrong due to confusion so my answer was
Answer: T(c)=c+160/4
The function T(c), which is the inverse of C(t), is T(c) = (c + 180) / 6.
Explanation:To find the inverse function T(c), we first have to rewrite the original function C(t) in terms of c. So, if C(t) = 6t - 180, we write it as c = 6t - 180.
Next, we swap the roles of c and t, so now t becomes the function of c i.e., we get t = 6c - 180.
Finally, we solve this equation for c to get the inverse function. Doing so will give us c = (t + 180) / 6. Hence the inverse function is T(c) = (c + 180) / 6.

find the quotient: -10/19 divided by (-5/7) ?
In mathematics, we convert division of fractions to multiplication by using the reciprocal of the divisor. By following these steps, -10/19 divided by (-5/7) simplifies to 14/19.
Explanation:The problem at hand involves the division of two fractions, -10/19 divided by (-5/7). In mathematics, the division of fractions is performed by converting the division operation into multiplication by making use of reciprocal of the divisor. That means we replace the division symbol between the two fractions with a multiplication symbol and inverse the divisor (which is the fraction that comes after the division symbol).
Let's perform the operation step-by-step:
Invert the divisor (i.e., flip fraction (-5/7) to (7/-5) or -7/5)Replace the division symbol with a multiplication symbol, we get: -10/19 * -7/5Multiply the numerators: (-10) * (-7) = 70Multiply the denominators: 19 * 5 = 95Combine the resulting numerators and denominators to form a fraction: 70/95Simplify the result: 14/19So, the result of -10/19 divided by (-5/7) is 14/19.

formula for the arithmetic sequence -11,-3,5,13,...
Remark
The difference is between any two terms. You should pick t3 and t4 which are both positive. That's easier to handle than a couple of minus signs.
d
t4 - t3 = d
13 - 5 = d
8 = d
a
the first term is - 11
Formula
t_n = a + (n-1)*d
t_n = -11 + (n-1)*8
Check
t_n = - 11 + (3-1)*8
t_3 = - 11 + 16
t_3 = 5 which it does.
Try t_5. It should be 21
t_5 = - 11 + (5 - 1)*8
t_5 = - 11 + 4 * 8
t_5 = -11 + 32
t_5 = 21
Answer
t_n = -11 + (n - 1)*8

How many lines of symmetry does this figure have?
There aren't any lines of symmetry because it is a scalene right triangle. (:
Answer:
The scalene triangle has no lines of symmetry.
Step-by-step explanation:
We can see that the given figure is a scalene right triangle.
A line of symmetry is a line that divides a figure into two mirror image halves. The line around which a figure is reflected over is called a line of symmetry.
The scalene triangle has no lines of symmetry. A scalene triangle is one which has no sides equal and no angles equal.

Which expression represents the distance between -14.6 and -5.2 on the number line?
If the expression represents the distance between -14.6 and -5.2 on the number line. The expression that represents the distance between -14.6 and -5.2 on the number line is 9.4.
What is distance?
Distance between these two points:
Distance = Larger value - Smaller value
Where:
Larger value = -5.2
Smaller value= -14.6
So,
Distance = -5.2 - (-14.6)
Distance = -5.2 + 14.6
Distance = 9.4
Therefore the expression that represents the distance between -14.6 and -5.2 on the number line is 9.4.

Identify the coordinates of four points on the line with each given slope and y-intercept. 0.2, y-intercept = 0.3
Slope = 0.2 and y-intercept = 0.3
The slope intercept form of line is
y=mx + b where m is the slope and b is the y intercept
So equation becomes y = 0.2 x + 0.3
To find coordinates of 4 points , we plug in some number for x and find out y
x y = 0.2 x + 0.3
0 y = 0.2 (0) + 0.3= 0.3
1 y = 0.2 (1) + 0.3= 0.5
2 y = 0.2 (2) + 0.3= 0.7
3 y = 0.2 (3) + 0.3= 0.9

Gabrielle's age is two times Mikhail's age. The sum of of their age is 66. What is Milkhail's age?
Final answer:
To find Mikhail's age, set up the equations based on the given information; Gabrielle's age is twice Mikhail's and their combined age is 66. Solving the equations shows that Mikhail is 22 years old.
Explanation:
The given problem is about determining Mikhail's age when Gabrielle's age is two times Mikhail's age and together their ages sum up to 66. We can set up equations to solve this problem. Let's denote Gabrielle's age as G and Mikhail's age as M.
From the problem we have two equations:
G = 2M (Gabrielle is twice as old as Mikhail)
G + M = 66 (Sum of their ages)
We can substitute the first equation into the second:
2M + M = 66
3M = 66
M = 66/3
M = 22
Therefore, Mikhail's age is 22 years old.

The equation of the inverse of the function is [tex]y=\sqrt{\frac{x+4}{9} }[/tex]
Given the expression y = 9x^2 -4
Replace y with x to have
x = 9y^2 -4
Make y the subject of the formula to get the inverse function
9y^2 = x+ 4
[tex]y^2 = \frac{x+4}{9} \\y =\sqrt{\frac{x+4}{9} }[/tex]
Hence the equation of the inverse of the function is [tex]y=\sqrt{\frac{x+4}{9} }[/tex]

A. The height of a building for 20 years.
B.The height of a person from birth till 20
C. the height of a tree for 20 years.
D. The height of an elephant for 20 years.
Option A is correct.
Cathy needs to collect linear data . She should collect the data of option A-The height of a building for 20 years.
Explanation:
Linear data is that data whose slope is always same. Here lets assume, initially the building had 2 floors. Each year 2 floors are added above the previous floors. So our coordinate will be (0,2) (1,4) (2,6) (3,8) and so on.
So slope = [tex]\frac{difference in y}{difference in x}[/tex]
= [tex]\frac{4-2}{1-0} = \frac{2}{1}[/tex]
= [tex]\frac{8-6}{3-2}[/tex] = [tex]\frac{2}{1}[/tex]
So, here slope is 2 for all coordinates.
