Rob travels 132 miles per hour. How long does it take him to travel 11 miles? Your answer should be in hours, accurate to at least the nearest tenth
keeping in mind that 1 hour has 60 minutes, then
[tex]\begin{array}{ccll} miles&minutes\\ \cline{1-2} 132 & 60\\ 11& x \end{array} \implies \cfrac{132}{11}=\cfrac{60}{x}\implies 12=\cfrac{60}{x} \\\\\\ 12x=60\implies x=\cfrac{60}{12}\implies x=5[/tex]

The table that shows a constant rate of change of -3 is Table D.
Option D is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The constant rate of change (r):
Take two ordered pairs (a, b) and (c, d)
= (d - b) / (c - a)
Now,
From Table D.
We see that,
r = (-1 - 2) / (-21 + 22) = -3/1 = -3
r = (-4 + 1) / (-20 + 21) = -3/1 = -3
r = (-7 + 4) / (-19 + 20) = -3/1 = -3
Thus,
The table that shows a constant rate of change of -3 is Table D.

Mrs. Kwan will teach 8 workshops next week. Each workshop is 2 hours long. Mrs. Kwan tries to tell a joke ever 1/3. How many times will she tell a joke by the end of the last workshop?
Assuming you meant every 1/3 hour, she will tell 48 jokes
1/3 hr = 20 mins
16 hrs = 960 mins
960/20= 48 jokes
You could also take 16 hrs and the 3 from 1/3, 16*3=48

A student says the first step of the proof is "Reflect △ABC in AB←→ to create △ABC′." Which of the following statements logically comes next?
Reflecting the triangle ABC implies that the new position would be a mirror of the previous position
The statement that logically comes next is (c) Translate triangle ABC, so that point A maps to point W
How to determine the next stepAfter reflecting the triangle ABC, the next step is to map point A to point W on the coordinate plane.
This is done by translating the triangle ABC i.e. by shifting or moving the triangle ABC so that points A and W would be on the same point
Hence, the statement that logically comes next is (c)

Aling Luz bought yards of linen cloth which cost Php 72.00 per
yard, She gave Php 1 000,00 to the cashier. How much change will she
8
Answer:
Php 973.00
Step-by-step explanation:
Aling Luz bought 3/8 yards of linen cloth which cost Php 72.00 per yard.She gave Php 1000.00 to the cashier.How much change will she?
Number of yards bought = 3/8
Cost of a yard = Phone 72.00
Cost of number of yards bought = Number of yards bought × Cost of a yard
= 3/8 × Php 72.00
= Php 27.00
She gave Php 1000.00 to the cashier.
How much change will she?
= Amount given to the cashier - cost of yards bought
= Php 1000.00 - Php 27.00
= Php 973.00

How do you these questions?
Answer:
a) s = 2a sinh(b/a)
b) 18 feet
Step-by-step explanation:
The arc length is:
s = ∫ √(1 + (dy/dx)²) dx
y = a cosh(x/a)
y = ½ a (e^(x/a) + e^(-x/a))
dy/dx = ½ a (1/a e^(x/a) − 1/a e^(-x/a))
dy/dx = ½ (e^(x/a) − e^(-x/a))
(dy/dx)² = ¼ (e^(2x/a) − 2 + e^(-2x/a))
Plugging in:
s = ∫ √(1 + ¼ (e^(2x/a) − 2 + e^(-2x/a))) dx
s = ∫ ½ √(4 + e^(2x/a) − 2 + e^(-2x/a)) dx
s = ∫ ½ √(e^(2x/a) + 2 + e^(-2x/a)) dx
s = ∫ ½ √(e^(x/a) + e^(-x/a))² dx
s = ∫ ½ (e^(x/a) + e^(-x/a)) dx
s = ½ (a e^(x/a) − a e^(-x/a))
s = ½ a (e^(x/a) − e^(-x/a))
Evaluate from x=-b to x=b:
s = ½ a (e^(b/a) − e^(-b/a)) − ½ a (e^(-b/a) − e^(b/a))
s = ½ a e^(b/a) − ½ a e^(-b/a) − ½ a e^(-b/a) + ½ a e^(b/a)
s = a e^(b/a) − a e^(-b/a)
s = a (e^(b/a) − e^(-b/a))
s = 2a sinh(b/a)
We know that s = 48, and b = 20. We also know y = 30 when x = b.
48 = 2a sinh(20/a)
24 = a sinh(20/a)
30 = a cosh(20/a)
Using the given identity:
cosh²(20/a) − sin²(20/a) = 1
a² cosh²(20/a) − a² sin²(20/a) = a²
30² − 24² = a²
a² = 324
a = 18

Which symbol can be used to correctly compare the two fractionsPlease help asap!!!
Use >, <, or =.
2/5 35/100
Answer:
The symbol we can be used is " > "
Step-by-step explanation:
To compare two fractions you must make their denominator equal
Example:
To compare the fractions [tex]\frac{3}{4}[/tex] and [tex]\frac{7}{50}[/tex] ,
You should make their denominators equal. Multiply 4 by 25 to get 100 and multiply 50 by 2 to get 100, So, [tex]\frac{3*25}{4*25}=\frac{75}{100}[/tex] and [tex]\frac{7*2}{50*2}=\frac{14}{100}[/tex]. Since 75 > 14, then [tex]\frac{75}{100}>\frac{14}{100}[/tex] ,Which means [tex]\frac{3}{4}>\frac{7}{50}[/tex]Let us solve the question
∵ The fractions are [tex]\frac{2}{5}[/tex] and [tex]\frac{35}{100}[/tex]
→ Change denominator 5 to 100 by multiplying it by 20
∵ [tex]\frac{2}{5} =\frac{2*20}{5*20}=\frac{40}{100}[/tex]
∵ 40 > 35
∴ [tex]\frac{40}{100}>\frac{35}{100}[/tex]
∴ [tex]\frac{2}{5}>\frac{35}{100}[/tex]
∴ The symbol we can be used is " > "

The equation y = 16.50x describes the amount of money Joey earns, where x is the number of hours he works and y is the amount of money he earns.
The table shows the amount of money Kaylee earns for different numbers of hours worked.
Kaylee’s Earnings
Time (h) 2 5 8 10
Money earned ($) 39 97.50 156 195
(a) How much money does Kaylee earn per hour? Show your work.
(b) Who earns more per hour? Justify your answer.
HELP ME PLEASEEEEE
Answer:
(a) Kaylee earns $19.50 per hour.
(b) Kaylee earns more money per hour than Joey.
Step-by-step explanation:
x = # of hrs. worked
y = amount of money earned
Joey:
y = 16.50x
Kaylee:
Time (h) 2, 5, 8, 10
Money earned ($) 39, 97.50, 156, 195
y = mx + b; Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will be using: (2,39) and (8,156) to find the slope of this table.
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{156-39}{8-2} \\\\m=\frac{117}{6} \\\\m=19.5[/tex]
y = mx + b
y = 19.5x + b
I will be using (2, 39) to find the value of b
(2, 39)
y = 19.5x + b
39 = 19.5(2) + b
39 = 39 + b
-39 -39
0 = b
y = 19.5x + b ==> y = 17.7x + 0 = OR y = 19.5x (since the value of b is 0)
(a) The question wants us to find out how money Kaylee earns per hour. Recall that x = # of hrs. worked and y = amount of money earned.
y = 19.5x
She earns $19.50 per hour.
(b)
Joey: y = 16.50x (earns $16.50 per hour)
Kaylee: y = 19.5x (earns $19.50 per hour)
As you can see, Kaylee earns more money per hour than Joey.
