Answer:
x ~0.9
Step-by-step explanation:
To solve for (x) in the given right triangle, use the trigonometric ratios, which are the following,
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
Each of the sides of a triangle is named with respect to the given angle. In this problem, one is given the side opposite to the given angle, and the side adjacent to it. Use the ratio of tangent (tan) to solve for the unknown side.
[tex]tan(83)=\frac{7}{x}[/tex]
Manipulate the equation so that it is solved for (x),
[tex]x=\frac{7}{tan(83)}[/tex]
x ~ 0.859

Alli has $382.45 in her checking account and $450 in her savings account. She writes a check for $400. Alli's bank automatically takes money from her savings to cover the amount of a check if the money in the checking account is not sufficient. Unfortunately for Alli, the bank also withdraws $25 from her savings account for this service. Once the check has cleared, how much money does Alli have in her savings account?
Answer:
Alli has $450 in her saving account bank withdraws $25 from her saving account
alli's bank automatically takes $400
after the check is cleared
she will get = $450+$400-$25 = $825
Step-by-step explanation:
hope it helps ❤️
The amount left in Alli's savings account after the check has cleared is $407.54.
it is given that
money in checking account= $382.45
money in savings account= $450
the value of check= $400
service charge deducted by bank in case money is not sufficient in check account = $25
What will be the amount left in the savings account of Alli after the clearance of the check?the amount left in Alli's savings account after clearance of check will be:
the amount already present in the savings account - extra money needed for clearance of check - Service charge levied by the bank.
the amount left in Alli's savings account after clearance of check
450-(400-382.54)-25 = $407.54
therefore, the amount left in Alli's savings account =$407.54

Write an equation of the line that passes through the points (-3, 3) and (0, -1)
Answer:

Find the slope:

b = -1The line is:

Just to be sure, the manager has six more samples taken:
33, 45, 34, 17, 1, and 29 errors, per 1,000 scans each
How reasonable is it to expect that the small sample represents larger samples?
Answer:1A. 20.5
2A. 14.54
1B. 14.625
2B. quite good reasonable
Step-by-step explanation:
Mean is used to measure central tendency (i.e. representative of data) and standard deviation is use to measure dispersion of data. The formula use to calculate mean and variance is :
1A. Mean of six sample =
⇒
⇒ Mean = 20.5
Standard deviation of six sample =
⇒ σ = 14.54
2A. Total number of error = 36 + 14 + 21 + 39 + 11 + 2 = 123
Total number of error made by all scans is 123 error per 6000 scans.
1B. Mean of all 12 samples is:
⇒
⇒ Mean = 23.5
Standard deviation of all 12 samples =
⇒ σ = 14.625
2B. Taking small sample instead of large sample can be quite risky sometimes as larger sample give us more accurate result than small sample.
But here we can take a small sample because the mean of both the size of the sample is near about.

Let x represent the number of batteries and y represent the cost of the batteries. A package of 8 rechargeable batteries costs $12. At this rate, how much would a package of 20 rechargeable batteries cost
Answer:
8 battery =12
20 battery =?(x)
8x=240
x=240÷8
x=30
for 20 battery..it would cost 30
Step-by-step explanation:
The cost of 20 rechargeable batteries will be $30.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The cost of A package of 8 rechargeable batteries = $12.
Now,
Since, The cost of A package of 8 rechargeable batteries = $12.
So, The cost of A package of 1 rechargeable batteries = $12/8
Hence, The cost of A package of 20 rechargeable batteries is,
= $12/8 x 20
= $30
Thus, The cost of 20 rechargeable batteries will be $30.

Give coordinates for any three points that are on the same vertical line. Include at least one point that has a mixed number as a coordinate. (Can the numbers be made up? I put in (1 1/2,4), (2,4), (5,4) as the answer. Is that correct?)
Answer: No
Step-by-step explanation:
Points inserted are

As all the points have the same y-coordinate, therefore, they must lie on the same horizontal line of [tex]y=4[/tex]

What values make an equivalent number sentence after completing the square?
Enter your answers in the boxes.
x2+8x+ ? = ?
Answer:
x²+8x+16=24
Step-by-step explanation:
x²+8x=7 (+16)
x²+8x+16=7+16=24
(x+4)²=24
The values to be entered in the boxes are 16 and 23.
Given the equation is [tex]x^2[/tex]+8x=7
To complete the square for the equation [tex]x^2[/tex] + 8x = 7, we need to add a constant term on both sides of the equation to create a perfect square trinomial on the left side.
First, take half of the coefficient of the x-term (8) and square it:
[tex](8/2)^2[/tex] = 16
Now, add 16 to both sides of the equation:
[tex]x^2[/tex] + 8x + 16 = 7 + 16
Simplifying:
[tex]x^2[/tex] + 8x + 16 = 23
Therefore, the equivalent number sentence after completing the square is [tex]x^2[/tex] + 8x + 16 = 23
The values to be entered in the boxes are 16 and 23.
Hence, [tex]x^2[/tex] + 8x + 16 = 23.
