Answer:
3.5 hours of studying to get a 75 on the exam.
Step-by-step explanation:
The y intercept in the graph is 40. This means that the constant in the linear equation is 40.
The slope of the equation is 10 because after the variable x travels one interval, the y travels 10.
To get the hours a student need to get 75 on the exam, we set the equation equal to 75.
75 = 10x + 40 where x = hours studied.
75 - 40 = 10x
x = 35/10
x = 3.5 hours

If possible, complete the equation below that uses the law of cosines to find the remaining side of the triangle.
Answers
Answer:
Option C.
a = 20.3
Step-by-step explanation:
Given:
m<A = 32°
a = ??
b = 16
c = 32
Required:
Find a
SOLUTION;
To find the missing side, a, of the triangle, apply the Law of Cosines, [tex] a^2 = b^2 + c^2 - 2bcCosA [/tex]
Plug in the values into the equation:
[tex] a^2 = 16^2 + 32^2 - 2(16)(32)Cos32 [/tex]
[tex] a^2 = 1,280 - 1,024*Cos32 [/tex]
[tex] a^2 = 1,280 - 868.40125 [/tex]
[tex] a^2 = 411.59875 [/tex]
[tex] a = \sqrt{411.59875} [/tex]
[tex] a = 20.3 [/tex] (nearest tenth)

As of the moment I am writing this question, the population of the United States is 326,891,705 people. You are building an app that targets the US population and expect to get 1/10 of 1% of the population using your app in the first 4 months. The estimated data you need to store per user averages 10 GB. What is the minimum storage you must plan to have in place for app to serve the users in the first 4 months
Answers
Answer:
3.3 PB
Step-by-step explanation:
It is given tat the population of the U.S = 326,891,705 people.
Population expected to use the app in first 4 months = 1/10 of 1%
Storage capacity of an user is = 10 GB
Therefore,
[tex]$\frac{1}{10} \text{ of}\ 1$[/tex] % = 0.1%
= 0.001
The user content = 0.001 x 326,891,705
= 326891.705 users
10 GB storage per user.
Therefore,
Size = 326891.705 x 10
= 3268917.05 GB
= 3.26 PB
Hence size of the minimum storage would be 3.3 PB.

Tamara receives a monthly salary of $875 plus 71/4% on all sales over a monthly quota of $400 calculate her monthly gross pay if her sales where $2180.
(Show work)
Answers
Answer:
Tamara's monthly salary was $ 1,190.95.
Step-by-step explanation:
Given that Tamara receives a salary of $ 875 plus 71/4% of all her monthly sales above $ 400, to determine how much money she earned in the month knowing that she made sales for $ 2,180, the following calculation must be performed:
2180 - 400 = 1780
71/4 = 17.75
1780 x 17.75 / 100 = 315.95
315.95 + 875 = X
1,190.95 = X
Thus, Tamara's monthly salary was $ 1,190.95.

Answers
The height of the tree as per sine of an angle in a right-angle triangle is 12.5 meters.
What is the sine of an angle in a right-angle triangle?Sine of an angle in a right-angle triangle is the ratio of the height to the hypotenuse of that triangle.
Here, the tree and it's shadow forms a right-angle triangle along with the base.
Let, the height of the triangle is x.
The length of the height of the hypotenuse is 25 meters.
The angle of elevation from the ground to the top of the tree is 30°.
Therefore, sin (30)° = (x / 25)
⇒ 0.5 = (x / 25)
⇒ x = 0.5 × 25
⇒ x = 12.5
Therefore, the height of the tree is 12.5 meters.

Use the line tool to graph the equation on the coordinate plane.
y = 3/4x
Answers
Step-by-step explanation:
in the equation y=mx+b, m corresponds to the slope, and b corresponds to the y-intercept. Since b is 0 at this case, we will start at (0,0). From here you can graph the line with the slope. Since it is 3/4, you would move up 3 units, and to the right 4 units to end up with the point (4,3). Now you have the two points (0,0) and (4,3), so all you need to do is connect them to form the line.
A bank deposit paying simple interest at the rate of 8%/year grew to a sum of $1300 in 6 months. Find the principal. (Round your answer to the nearest cent.)
Answers
Answer:
$1,250
Step-by-step explanation:
The rate is 8%
= 8/100
= 0.08
Time is 6 months
= 1/2 year
Therefore the principal can be calculated as follows
Principal × (1+0.08(1/2) = 1300
Principal × 1+ 0.04 = 1300
Principal × 1.04= 1300
Principal= 1300/1.04
Principal = $1,250
Hence the principal is $1,250

There are two approaches to this question.
Approach 1:
We can compute the slope of a line by calculating its mean variation, the rise over run. Mathematicaly:
[tex]a=\frac{\Delta y}{\Delta x}[/tex]
The two points we have are [tex]P1 = (1,3)[/tex] and[tex]P2 = (4,3)[/tex]. Plugging the values into the expression we get
[tex]a=\frac{3-3}{4-1} \\a=0[/tex]
Therefore, the slope of the line is zero.
Approach 2:
The slope of the line is given by the angle [tex]\alpha[/tex] it makes with the X axis, in other words,
[tex]a = tan(\alpha)[/tex]
Note that the angle the line makes is exaclty zero. Therefore:
[tex]a= tan(0)\\a=0[/tex]
Again, we get that the slope of the line is zero.
In general, the slope of any horizontal line will always be zero.
