Step-by-step explanation:
In this question we need to decrease 216 by [tex]37\dfrac{1}{2}\%[/tex] or 37.5 %.
For this, firstly find 37.5 % of 216.
[tex]37.5\%\ \text{of}\ 216=\dfrac{37.5}{100}\times 216\\\\=81[/tex]
Now subtracting 81 from 216 to find decrease of 216 by 37.5 %.
So,
216-81 = 135
Hence, 135 is the decrease of 216 by 37.5 %.
The percentage decrease of 216 by 37 1/2% be is 135
Given:
Original value = 216
Percentage decrease = 37 ½%
Decrease = 37 ½% of 216
= 75/2 ÷ 100 × 216
= 37.5 / 100 × 216
= 0.375 × 216
= 81
New value = Original value - Decrease
= 216 - 81
= 135
Therefore, the percentage decrease of 216 by 37 1/2% be is 135

A factory produces 42,000 computer monitors per day. The manager of the factory claims that fewer than 660 defective computer monitors are produced each day. In a random sample of 240 computer monitors, there are 2 defective computer monitors. Determine whether the manager's claim is likely to be true. Explain.
Answer:
The manager's claim is likely to be true.Step-by-step explanation:
We are given that the factory produces 42,000 computer monitors per day
And the claim is of this amount produces fewer than 660 are defective.
a random sample shows that of 240 monitors 2 are defective
to verify the factory managers claim we need to know how many 240s are there in 42000
=42000/240= 175
Since each 240 will give 2 defective monitors
175 will give= 175*2= 350
350 is less than 660 hence the managers claim is correct

y =6x-15
Please help
Answer:
y=15+-6x
Step-by-step explanation:
y = -6x + 15
Reorder the terms:
y = 15 + -6x
Solving
y = 15 + -6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 15 + -6x
Step-by-step explanation:
[tex]6x - 15 = y \\ 6x = y + 15 \\ \frac{6x}{6} = \frac{y + 15}{6} \\ x = \frac{y + 15}{6} \\ x = \frac{y}{6} + \frac{5}{2} [/tex]

Answer:
5x^2 + -3
Step-by-step explanation:
For this problem, we will simply simplify the expression by combining like terms.
(-3x^3 - 7x^5 - 3) + (5x^2 + 3x^3 + 7x^5)
= 7x^5 + -7x^5 + 3x^3 + -3x^3 + 5x^2 + -3
= 0 + 0 + 5x^2 + -3
= 5x^2 + -3
Thus, the simplified expression is 5x^2 + -3.

What is the equation of a horizontal line passing through the point (-3, 8)?
A: x=-3
B: y=8
C: x=5
D: y=-11
Answer:
B
Step-by-step explanation:
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 3, 8 ) with y- coordinate of 8, thus
y = 8 ← equation of horizontal line
how does 1/12 - 5/6 = 9/12 um tring to learn how to add this like ?
Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
We need to get a common denominator of 12
1/12 - 5/6*2/2 = -9 /12
1/12 - 10/12 = -9/12
Since the denominators are the same, we can subtract the numerators
1-10 = -9
-9/12 = - 9/12
We can simplify -9/12 by dividing the top and bottom by 3
-9/3 = -3
12 /3 = 4
-9/12 = -3/4
Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
1st, we need to identify the Least Common Multiplier of 12 and 6
in this case, the LCM is 12
for 5/6 = (5*2) / (6*2) = 10/12
2nd, adjust the fractions based on the LCM
= 1 / 12 - 10 / 12
= 1 - 10 / 12
= -9 / 12 ---- simplify -3 / 4
(01.06) Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x)= 3x − 3 The function g(x) going through 0, 2 and 1, 5 (1 point) The function f(x) has a larger slope. The function g(x) has a larger slope. They both have the same slope. The relationship between slopes cannot be determined.
Answer:
They both have the same slopeStep-by-step explanation:
The standard equation of a given line is expressed as y = mx+c where m is the slope and c is the intercept.
given the function f(x)= 3x − 3, comparing this equation with the standard format, we will have;
mx = 3x
Divide through by x
mx/x = 3x/x
m = 3
Hence the slope of the function f(x)= 3x − 3 is 3.
For a function g(x) passing through the points (0, 2) and (1, 5), to determine the slope, we will use the formula for calculating slope expressed as;
m = Δy/Δx = y₂-y₁/x₂-x₁
From the coordinates, x₁ = 0, y₁ = 2, x₂ = 1, y₂ = 5
m = 5-2/1-0
m = 3/1 = 3
Hence the slope of g(x) passing through the points (0, 2) and (1, 5) is also 3.
This shows that both functions have the same slope.

Mark would like to build a rectangle frame. The dimensions of the frame are unknown, but the perimeter of the frame must be 80 yards. The length of the frame is six less than the width. What is the length of the frame?
Answer:
The length of the frame is 17
Step-by-step explanation:
The computation of the length of the frame is shown below:
As we know that
The perimeter of a rectangle is
= 2 (length + width)
where,
let us assume the width be x
So, the length is x - 6
And, the perimeter is 80 yards
So, now put these values to the above formula
80 yards = 2 (x - 6+ x)
80 yards = 2 (2x - 6)
80 yards = 4x - 12
92 = 4x
x = 23
So, the length of the frame is
= 23 - 6
= 17

A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?
Answer:
The building to the left is taller.
Step-by-step explanation:
Building on right:
tan 40° = a/56
a = 56 tan 40° = 46.99
Building on left:
tan 50° = b/49
b = 49 tan 50° = 58.40
The building to the left is taller.
HELP! The length of a rectangle is 4 meters less than twice it's width. If the area of the rectangle is 96 inches what is the width?
Answer:
8cm
Step-by-step explanation:
1. x = width
length = 2x - 4
(2x - 4)x = 96
2x ^ 2 - 4x - 96 = 0
x ^ 2 - 2x - 48 = 0
(x + 6)(x - 8) = 0
Since the width cannot be negative, the width would be 8cm.
