Answer:
-54
Step-by-step explanation:
When you solve any equation always remember to use PEMDAS (Parentheses Exponents, Multiplication, Division, Addition and Subtraction) use also move left to right. The correct way to solve this is
2(4-16)-30
2(-12)-30
-24-30
-54
Hope this helped
Answer:
Step-by-step explanation:
Third line. "24 - (-30)" has to multiply 2 with -12, so it would be "-24" and not "24".
2(4 - 16) - (-30)
2(-12) + 30
-24 + 30 = 6

A container holds 80,000 ounces of water. There is a small leak in the container. Every 96 minutes, 0.3 ounces of water leak out. Represent the total change in the amount of water in the container after 8 hours.
Answer:
Step-by-step explanation:
8hours=60×8= 480 minute
96minutes=0.3 ounces
480minutes =x ounces (use crisscross)
96x =144minutes
X= 144/96=1.5 ounces
Total change in the amount of water is
80,000-1.5=79998.5 ounces
describe how you would graph 2x+3y=6
Answer:
First get y by itself. (y=-2/3x +2). The y-intercept is at 2 and the slope is -2/3 so starting at (0,2) you would go down two and right three and continue doing that to create your graph.

How do you do this question?
Answer:
(a) y = ¼ sin(x² + C)
(b) y = ¼ sin(x²)
Step-by-step explanation:
(a) dy/dx = ½ x √(1 − 16y²)
dy / √(1 − 16y²) = ½ x dx
4 dy / √(1 − 16y²) = 2x dx
sin⁻¹(4y) = x² + C
4y = sin(x² + C)
y = ¼ sin(x² + C)
(b) When x=0, y=0.
0 = ¼ sin(C)
C = 0
y = ¼ sin(x²)

What slope would make the lines
perpendicular?
y = -x + 2
y = [?]x – 1
Answer:
The inverse reciprocal.
The slope of a perpendicular line is always the inverse reciprocal.
Answer:
3Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
The slope m of a perpendicular line is always the inverse reciprocal.
Therefore, our mperpendicular is 3.

A sample of 68 electric motors had a mean efficiency of 0.595 (assume that the standard deviation is known to be 0.05). Let μ represent the mean efficiency of electric motors of this type.
Find the P-value for testing H0 : μ ≥ 0.6 versus H1 : μ < 0.6.
P-value =
The p-value for the test hypothesis is of 0.4681.
How to find the p-value of the test?We are working with proportions in this problem, hence the z-distribution is used, first we find the test statistic, and then with the test statistic, we find the p-value.
The test statistic is given according to the following rule:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which the parameters of the formula are described as follows:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.In the context of this problem, the values of these parameters are given by:
[tex]p = 0.6, \overline{p} = 0.595, n = 68[/tex]
Hence the test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.595 - 0.6}{\sqrt{\frac{0.6(0.4)}{68}}}[/tex]
z = -0.08
Using a z-distribution calculator, with a left-tailed test, as we are testing if the proportion is less than a value, the p-value is of 0.4681.

The function C gives the cost, in dollars, to shred w pounds of confidential documents of a company.
Interpret the meaning of the following math sentence in the context of the problem. C'(500) = 80.
The model shows cost is increasing at a rate of $80 dollars/pound.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
We given C gives the cost, in dollars, to shred w pounds of confidential documents of a company.
Also, the modeled equation :C’(500)=80
which shows that for 500 pounds of documents, the cost is increasing at a rate of $80 dollars/pound.
Hence, one pound costs $80.
