Answer:
-3(43)= -129
−3(3) = −9
−3(2) = −6
−3(1) = −3
−3(0) = 0
−3(−1) = 3
−3(−2) = 6
-3(-3)= 9
Step-by-step explanation:
As the factor decreases by 1, the product increases by 3. So −3(−1) = 3, −3(−2) = 6.
Multiplying −3 by a negative integer gives a positive number.
The product of a positive number and a negative number is negative.
Simplify the expression.

Gentry Industries has the following information about maintenance costs in the past six months.
Month Machine _Hours Amount
January 200 $2,800
February 350 3,000
March 450 4,000
April 500 5,000
May 600 5,200
June 580 5,800
How much would Gentry pay if maintenance machine hours are 550?
Answer:
Total cost= $5,425
Step-by-step explanation:
Giving the following information:
Month Machine _Hours Amount
January 200 $2,800
February 350 3,000
March 450 4,000
April 500 5,000
May 600 5,200
June 580 5,800
First, we need to calculate the fixed and variable costs. To do it, we will use the high-low method:
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (5,800 - 2,800) / (600 - 200)
Variable cost per unit= $7.5 per hour
Fixed costs= Highest activity cost - (Variable cost per unit * HAU)
Fixed costs= 5,800 - (7.5*600)
Fixed costs= $1,300
Fixed costs= LAC - (Variable cost per unit* LAU)
Fixed costs= 2,800 - (7.5*200)
Fixed costs= $1,300
Now, we can determine the total cost for 550 hours:
Total cost= 1,300 + 7.5*550
Total cost= $5,425

In which equation is the product greater than 3?
A. 3/4x3
B. 3/2x3
C. 1/12x3
D. 9/10x3
Answer:
B
Step-by-step explanation:
all you need to do for this is multiply the numerator by the 3.
3/4 times 3 = 9/4- thats not more than 3
3/2 times 3 = 9/2 - thats more than 3
1/12 times 3 = 3/12- thats not more than 3
9/10 times 3 = 27/10 thats not more than 3

Find the value of X. Round to the nearest 10th
Answer:
Step-by-step explanation:
You have to use the tangent.
Tan(y) = opposite / adjacent
tan(10) = x / 500
tan(10) = 0.1763
0.1763 = x / 500
500 * 0.1763 = x
x = 88.1635
x = 88.2

In a cheese factory, 4.5-kg blocks of cheese are cut manually. For a large number of blocks, the standard deviation of the cutting process is measured and found to be 0.10 kg. The measurement was done with a scale with an accuracy of 1.5% of the full scale of 12 kg. Calculate the total uncertainty of the weight of the blocks of cheese at a 95 % confidence level.
Answer:
0.2690 kg
Step-by-step explanation:
Given that:
For cutting a 4.5 kg block of cheese; the standard deviation:
[tex]S_x = 0.1 \ kg[/tex]
For a large no of blocks, at 95% confidence level;
Using the t table; where the degree of freedom is infinity or > 30
t-distribution (t) = 2
∴
[tex]P_x = tS_x[/tex]
[tex]P_x = 2 \times 0.1[/tex]
[tex]P_x = 0.2 \ kg[/tex]
The system uncertainty as a result of the accuracy [tex]B_x[/tex] is:
[tex]B_x = 1.5\% \ of \ reading[/tex]
[tex]B_x = (\dfrac{1.5}{100})(12 kg)[/tex]
[tex]B_x = 0.18 \ kg[/tex]
The total uncertainty for a single experiment with a 95% confidence interval will be:
[tex]w_s = ( B_x^2 + P_x^2)^{\frac{1}{2}[/tex]
[tex]w_s = (0.18^2 + 0.2^2)^{\frac{1}{2}[/tex]
[tex]\mathbf{w_s = 0.2690 \ kg}[/tex]

What is the perimeter of this shape
9514 1404 393
Answer:
72.6 cm
Step-by-step explanation:
It is the perimeter of the overall rectangle plus twice the depth of the notch.*
P = 2(L+W) +2d
P = 2(16 cm + 13 cm + 7.3 cm) = 2(36.3 cm)
P = 72.6 cm
The perimeter of the shape is 72.6 cm.
_____
* You may be able to visualize this if you imagine the bottom (top) of the notch translated out (down) to the edge of the rectangle. That translation does not affect the length of the line segment, but helps convince you that only the two legs of the notch are added to the perimeter of the rectangle.
