Answer:
I think the ans is A. inverse.
Ron asked 18 classmates whether they prefer granola bars over muffins. he used a calculator to compare the number of classmates who said yes to the total number he surveyed. the calculator showed the result as 0.66666667. how many students prefer granola bars over muffins?
Explanation:
Multiply 0.66666667 with 18 to get
0.66666667*18 = 12.00000006
The 6 at the very end is due to rounding error. In reality the 6's in 0.66666667 should go on forever. That 7 is from rounding up.
Anyways, the result 12.00000006 should be 12 exactly.
Note how
12/18 = 0.66666667
when using a calculator.
Answer:
12
Step-by-step explanation:
Use equilvalent fractions 0.6 repeating is 2/3 than convert it over 18 students which is equal to 12/18 students chose granola bars.
Evaluate 20x y given that x=15 and y= 10.
Answer:
3000
Step-by-step explanation:
20xy20×15×10just let the x and y into it..Tasha was $422.75 last week. Of that paycheck $42.75 was extra overtime pay for 3 hours. If the rest of the check was Tasha’s weekly earnings for 40 hours, what is her weekly per-hour rate?
The solution is $ 9.50
The weekly per hour rate of Tasha is $ 9.50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The weekly per hour of Tasha last week = $ 422.75
The extra overtime pay of Tasha for 3 hours = $ 42.75
The total number of hours working = 40 hours
So , the equation will be
The weekly per hour of Tasha without overtime = weekly per hour of Tasha last week - overtime pay of Tasha for 3 hours
Substituting the values in the equation , we get
The weekly per hour rate of Tasha without overtime = 422.75 - 42.75
The weekly per hour of Tasha without overtime = $ 380
So , The weekly per hour rate of Tasha A = The weekly per hour rate of Tasha without overtime / total number of hours working
Substituting the values in the equation , we get
The weekly per hour rate of Tasha A = 380 / 40
The weekly per hour rate of Tasha A = $ 9.50
Therefore , the value of A is $ 9.50
Hence , The weekly per hour rate of Tasha is $ 9.50

Rose has a fish tank in the shape of a rectangular prism. The fish tank has a length of 20 inches and a width of 10 inches Rose pours 15 gallons of water into the fish tank How
hoh, to the nearest tenth of an inch, will the water reach in the tank
photo cubic foot of volume holds approximately 746 gallons of water
inches
Copyright 2020 Illuminate Education, Inc. All Rights Reserved
Answer:
17.3 in
Step-by-step explanation:
Given the following :
Length of tank = 20 inches
Width of tank = 10 inches
Amount of water poured into tank = 15 gallons
Volume(V) of tank (rectangular prism)
V = Length × width × height
Height = h
1 gallon = 231 inch³
15 gallons = (231 × 15) = 3465 in³
Hence V = 3465 in³
3465in³ = 20 in × 10 in × h
3465 in³ = 200h
h = 3465 / 200
h = 17.325 in
Height = 17.3 in ( nearest tenth)

In the figure below, K lies between J and L. Find the location of K so that JK is 1/7 of JL.
Answer:
-22 is the value of K.
Step-by-step explanation:
A simple way to see how far a mid-point or end-point is from another is by adding or subtracting. For this figure I added to see how many numbers would add twice to get from -15 to -29. -14 is the exact number from -15 to -29; divide that by 2 to get half of -14 which is -7. -7 + (-15) gives you -22.
The location of K so that JK is 1/7 of JL is -22.
Given that, K lies between J and L.
We need to find the location of K so that JK is 1/7 of JL.
What is a line segment?In geometry, a line segment is a part of a line that is bounded by two distinct end points and contains every point on the line that is between its endpoints.
Now, the distance between the points J and L on the number line is 14.
So, 1/7(14)=2

Katie has a collection of nickels, dimes and quarters with a total value of $3.95. There are 4 more dimes than nickels and 3 more quarters than nickels, how many of each coin does she have?
Answer:
She has 7 nickels, 11 dimes and 10 quarters
Step-by-step explanation:
Total value =$3.95
Let
Nickel = x
Dimes = x + 4
Quarters = x + 3
Every
Nickel = 5 cents
Dimes = 10 cents
Quarters = 25 cents
Total cents = $3.95 × 100
= $395
5n + 10d + 25q = 395
5(x) + 10(x+4) + 25(x+3) = 395
5x + 10x + 40 + 25x + 75 = 395
40x + 115 = 395
40x = 395 - 115
40x = 280
Divide both sides by 40
x= 280/40
= 7
x= 7
Nickel = x = 7
Dimes = x + 4
=7+4
=11
Quarters = x + 3
=7+3
=10

Part A
Answers:
Coefficient = 10.50 or 15 (pick one value)Variable = h or c (pick one)Constant = 50------------------
Explanation:
The variables are simply letters. They are placeholders for numbers to be plugged in later. Think of them like empty boxes where numbers will go. In this case, the variable h represents the number of hours Tyler works, and c is the number of new accounts she opens.
The coefficients are the numbers multiplied with the variables. They are to the left of the variable.
The constant 50 is not attached to any variable.
===================================
Part B
Answer: She earns $618.5
-------------------
Explanation:
We're told she worked 37 hours. So we'll replace h with 37.
Also, she opened 12 new accounts. So c = 12
This means...
10.50*h + 15*c + 50
10.50*37 + 15*12 + 50
388.5 + 180 + 50
618.5
is the amount she earns
===================================
Part C
Answer: The coefficient changes. Specifically, the coefficient 10.50 changes to 11.25
-------------------
Explanation:
The constant never changes (hence the name) no matter how much of a raise Tyler gets. The other coefficient doesn't change either because she would still get $15 per new account. All that's changed is the hourly wage.
If we're told that Tyler got a raise to $11.25 per hour and she now earned $20 per new account, then both coefficients would change and the new equation would be 11.25h+20c+50
Solve the given equation for h:
A = 1/2 bh
A = 1/2 bh
Let's simplify the right side.
A = (bh) / 2
Multiply both sides by 2
2A = bh
Divide both sides by b
(2A) / b = h
Dividing circumference with radius
If you divide the circumference C over the radius r, you get 2pi
2pi = C/r
this is because
C = 2pi*r

C = pi*d
which works because d = 2r, ie the diameter is twice the radius.

12 people can comfortably fit in a 5 x 5 foot square. Use this value to estimate the size of a crowd that is 8 feet deep on both sides of the street along a 2 mile section of a parade route.
Answer:
40,550
Step-by-step explanation:
Given that 12 people can comfortably fit in a 5 × 5 foot square
Area of square = 5²= 25 ft²
The dimension Given by : 8 feets depth on both sides along a 2 mile section signifies a rectangular area.
Area of rectangle = (length × width)
Recall :
1 mile = 5280 feets
2 miles = 5280 × 2 = 10,560 feets
Area = 8 × 10560 = 84480 sq feets
84480 / 25 = 3379.2
Estimated number of people will be :
3379.2 × 12 = 40,550.4
Hence, estimated number of people = 40,550
