Answer:
13.4lbs
Step-by-step explanation:
10.2/52 = 0.2lbs per inch
0.2(67) = 13.4lbs
Using unitary method, the weight of a 67 inch steel bar is 13.4 lbs.
What is unitary method?The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Weight of 52 inch flat steel bar = 10.4 lbs.
Weight of 1 inch flat steel bar = 10.4/52 = 0.2 lbs.
Weight of 67 inch flat steel bar = 0.2 * 67 = 13.4 lbs.

Solve for m. –5 − 5m = –6m
m= _
Answer:
M = 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5−5m=−6m
−5+−5m=−6m
−5m−5=−6m
Step 2: Add 6m to both sides.
−5m−5+6m=−6m+6m
m−5=0
Step 3: Add 5 to both sides.
m−5+5=0+5
m=5

What is the next term of the geometric sequence?
7, 21, 63
First find the common ratio of this geometric sequence.
We will use [tex]r = \frac{a2 }{a1 }[/tex].
The second term is 21 and the first term is 7.
So we have [tex]\frac{21}{7}[/tex] and this reduces to [tex]\frac{3}{1}[/tex] or 3.
So, we take the last term in our geometric sequence
and multiply it by the common ratio we just found.
So we have 63 · 3 which is 189.
So the next term in this geometric sequence is 189.

Which of the following could be the equation of the function below?
On a coordinate plane, a curve crosses the y-axis at y = negative 1.5. It has a maximum at negative 1.5 and a minimum at negative 2.5. It goes through 2 cycles at pi.
y = 0.5 cosine (2 (x minus StartFraction pi Over 2 EndFraction)) + 2
y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2
y = 0.5 cosine (4 (x + pi)) + 2
y = 0.5 cosine (2 (x minus pi)) minus 2
Answer:
y = 0.5 cosine (4 (x - pi/2)) - 2
Step-by-step explanation:
Taking the general form:
y = A cosine (Bx - Cπ)) + D
In the following case. the constants are:
y = 0.5 cosine (4x - 2π)) - 2
A: 0.5
B: 4
C: 2π
D: -2
The range of this function is:
range = [-|A|+D, |A|+D]
range = [-0.5-2, 0.5-2]
range = [-2.5, -1.5]
Which coincides with "It has a maximum at negative 1.5 and a minimum at negative 2.5"
At x = 0, the function value is:
y = 0.5 cosine (4(0) - 2π)) - 2
y = 0.5 - 2 = -1.5
As indicated in "a curve crosses the y-axis at y = negative 1.5"
The period of the function is:
period: 2π/B
period = 2π/4 = π/2 or 2 cycles at π
as described in "It goes through 2 cycles at pi."
Answer:
B) y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2

AJ is the bisector of ∠HJI. Determine the value of x.
Question 2 options:
A)
12
B)
10
C)
2.5
D)
22.5
The value of x is 2.5 if the AJ is the bisector of ∠HJI option (C) 2.5 is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a triangle shown in the picture.
AJ is the bisector of ∠HJI.
In this case the ratio between the adjacent sides are equal.
[tex]\rm \dfrac{8}{15}=\dfrac{4}{3x}[/tex]
After cross multiplication:
24x = 60
x = 2.5
Thus, the value of x is 2.5 if the AJ is the bisector of ∠HJI option (C) 2.5 is correct.

Simplify the following expression.
(13x+ 9) + (38x+33y)
A. 51x + 4y
B. 22x + 46y
C. 22x + 42y
D. 51x+ 42y
Answer:
The answer would be D.
Step-by-step explanation:
All you have to do is combine like terms.
Pretend that the parenthesis aren't there. 13x + 9y + 38x + 33y.
When you combine like terms, you add or subtract the terms that have the same variable attached.
13x + 38x = 51x.
9y + 33y = 42y
51x + 42y.
