What is the value of 80-2n when n=4
A: 66
B: 72
C: 76
D: 86
Answer:
B) 72
Step-by-step explanation:
The value of 80-2n when n=4 can be found by substituting n=4 into the expression and simplifying. Therefore:
80-2n = 80 - 2(4) = 80 - 8 = 72
Therefore, the answer is B) 72.
[tex] \sf80 - 2n[/tex]
Put n = 4
[tex] \tt80 - 2 \times 4 \\ \tt80 - 8 \\ \boxed{ \sf\underline{ \underline{72}}}[/tex]
Thus, The correct answer is option B!! :)Using the set numbers

The expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. If the length is Fraction 2 over 3 unit and the width is Fraction 1 over 3 unit, what is the perimeter of the rectangle in units? (3 points)
Group of answer choices
Fraction 2 over 3 unit
1 unit
1 Fraction 2 over 3 units
2 units
Answer:
1 unit
Step-by-step explanation:
The expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. If the length is 2/3 unit, and the width is 1/3 unit, what is the perimeter of the rectangle in units?
perimeter = 2(l + w)
perimeter = 2(2/3 + 1/3)
perimeter = 2(3/3) = 2(1)
perimeter = 1
Answer: 1 unit
Answer:1 Fraction 2 over 3 units

help please and thanks! mathematics.
Answer:
27 cm squared
Step-by-step explanation:
r = half of the diameter = 8 cm
area of circle = pi(r)^2 = 3.14 x (8 cm)^2 = 200.96 cm squared
area of rectangle = 16 cm x 8 cm = 128 cm squared
area of shaded region = area of the rectangle - (half of the area of the circle)
half of the area of the circle = 100.48 cm squared
therefore, area of shaded region = 128 cm squared - 100.48 cm squared
= 27.52 cm squared

====================================================
Explanation:
Let's label the given points A, B and C
A = (-6, -2)B = (-4, 7)C = (3, 5)To move from B to C, we do two things in either order:
Go down 2Go right 7This motion of "down 2, right 7" is copied or mirrored when we go from A to D. This is to ensure that BC is parallel to AD.
Start at point A and go down 2 units to get to (-6, -4). Then move 7 units to the right to arrive at (1, -4) which is the location of point D. You can use a tool like GeoGebra to verify the answer is correct.

Quotient with remainder: 1-digit divisor, 2-digit dividend for 59 divide by 9
Answer:
6 remainder of 5
Step-by-step explanation:
59 does not divise cleanly so you to the closest number that does and that number is 6 then you minus 59 from 54 bc 9 times 6 is 54 and 59 minus 54 is 5 so five is what remains meaning it becomes remainder 5
Two cars travel at the same speed to different destinations. Car A reaches its destination in 40 minutes. Car B reaches its destination in 50 minutes. Car B travels 9 miles farther than Car A. How fast do the cars travel?
Answer:
54 mph
Step-by-step explanation:
Since Car B travels 9 more miles in 10 more minutes, you would need to multiply 10 by 6 and 9 by 6 to get 54 miles per 60 minutes or 54 mph. And this would work because Car A would travel 36 miles and Car B would travel 45 miles and 45 - 36 is 9.
Consider rhombus ABCD, with side length 6:
This is rolled to form a cylinder of volume 27/2 by taping AD to BC:
What is sin(angle BAD)?
Answer: The circumference of the cylinder's base is 6 units.
Radius = 1/2(6/pi)
Volume = r2pi*h
h = (27/2) / r2pi
sin(∠BAD) = h / 6
What is the slope of the line that contains the points negative 3, negative seven halves and (2, −4)?
one fourth
one tenth
negative one tenth
negative one fourth
This answer was generated by an AI and may be incorrect.
The slope of a line can be found using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
Plugging in the given points, we get:
m = (-4 - (-7/2)) / (2 - (-3)) = 3/2 / 5 = 3/10
So, the slope of the line is 3/10, which is equal to one tenth.
Therefore, the answer is "one tenth."

Q.7d) q.7 find all below.
Answer:
a) 2/7 cup
b) k = 2/7
Step-by-step explanation:
2 cups of red paint (R) require 7 cups of white paint(W)
We can write this as a proportion equation:
R = k.W
where k is the constant of proportionality
Given R =2 when W = 7 we get
2 = k . 7
k = 2/7
Constant of proportionality = 2/7
So for 1 cup of White paint we will need
R = 2/7 x 1 = 2/7 cup

Step-by-step explanation:
We want to multiply the following 2 fractions:
3
4
x
36
1
Multiplying 2 fractions involves multiplying both numerators divided by both denominators.
Numerator 1 x Numerator 2
Denominator 1 x Denominator 2
In this case, Numerator 1 = 3, Denominator 1 = 4, Numerator 2 = 36, Denominator 2 = 1, so we have:
3 x 36
4 x 1
108
4
Now that we have our preliminary answer, we need to reduce it down as much as possible.
From our GCF Calculator, we see that the highest number that reduces 108 and 4 down to an integer is 4.
This number, 4, is called our Greatest Common Factor (GCF), and will be used to reduce both numerator and denominator as seen below.
Reducing the numerator gives us: (1/4) x 108 = 27
Reducing the denominator gives us: (1/4) x 4 = 1
Our answer is just the reduced numerator divided by the reduced denominator.
Since our reduced answer is a whole number, we remove the one from the denominator and write it as:
Answer = 27

Product is the answer.Multiplicand is the first number.Multiplier is the second number.In order to pass this year’s math class, Miriam needs to earn at least an 82%. Write an inequality that shows the scores Miriam could get to pass her math class.
Answer:
Step-by-step explanation:
The inequality that shows the scores Miriam could get to pass her math class will be x ≥ 0.82y.
What is inequality?
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
To pass this year’s math class, Miriam needs to earn at least 82%.
Let 'x' be the number of marks that Miriam needs to pass and 'y' be the total marks. Then the inequality is given as,
(x / y) × 100 ≥ 82%
Simplify the inequality, then we have
(x / y) × 100 ≥ 82%
(x / y) ≥ 0.82
x ≥ 0.82y
The inequality that shows the scores Miriam could get to pass her math class will be x ≥ 0.82y.
