Answer:
4.718592
Step-by-step explanation:
To get to -14.4 from 18 you multiply 18 x 0.8
Repeat that until you get to the 7th term
18 (1st)
18 x 0.8 = -14.4 (2nd)
-14.4 x 0.8 = 11.52 (3rd)
11.52 x 0.8 = 9.216 (4th)
9.216 x 0.8 = 7.3728 (5th)
7.3728 x 0.8 = 5.89824 (6th)
5.89824 x 0.8 = 4.718592 (7th)

this is 8th grade math can someone PLEASE answer number 9
8) y intercept is (0, 15) or 15
slope is 10 (the y intercept represents how much it would cost to open an online gaming account and the slope represents how much each game costs after you open an online gaming account, including the $15 fee to open the account)
9) y=10x+15
10) you can look at the graph where it says number of games and go to 6 and go up until you reach the line and look at the side where it says cost (dollars) and then you will see that 6 games cost $75
A 135.8 foot wire is attached to the top of the tower. If the wire is attached to the ground 30 feet from the bottom of the tower, then what angle does the wire make with the ground?
Answer:
77.23°
Step-by-step explanation:
Given that,
A 135.8 foot wire is attached to the top of the tower.
The wire is attached to the ground 30 feet from the bottom of the tower.
It means,
If we consider a triangle such that hypotenuse is 135.8 foot and base is 30 feet, it means we can use the trigonometry as follows :
[tex]\cos\theta=\dfrac{B}{H}\\\\\cos\theta=\dfrac{30}{135.8}\\\\\theta=77.23^{\circ}[/tex]
So, the angle the wire make with the ground is equal to 77.23°.

In pqr the measure of r is 90 degrees the measure of q is 38 degrees and qr is 8.8 feet. Find the length of pq to the nearest tenth of a foot
Answer:
11.2 feets
Step-by-step explanation:
Angle, P = 180 - (38 + 90) = 52
Using trigonometry :
Length pq:
SinP = opposite / hypotenus
Sin52 = 8.8 / pq
0.7880107 * pq = 8.8
pq = 8.8 / 0.7880107
pq = 11.167361
Hence, length of pq = 11.2 feets
the area of a rectangle is 96m^2 and the circumference is 39.2m. Determine the dimensions if the rectangle
Answer:
Dimension => 10 m × 9.6 m
Step-by-step explanation:
From the question given above, the following data were obtained:
Area (A) = 96 m²
Circumference (C) = 39.2 m
Dimension =.?
Next, we shall determine the Lenght and breadth of the rectangle. This can be obtained as follow:
Let L be the Lenght
Let B be the breadth
Area of a rectangle = L × B
96 = L × B ..... (1)
Circumference of rectangle = 2(L + B)
39.2 = 2(L + B) .... (2)
From equation 2, make L the subject
39.2 = 2(L + B)
Divide both side by 2
39.2 /2 = L + B
19.6 = L + B
Rearrange
L = 19.6 – B ....(3)
Substitute the value of L in equation 3 into equation 1
96 = L × B
L = 19.6 – B
96 = (19.6 – B ) × B
Clear bracket
96 = 19.6B – B²
Rearrange
B² – 19.6B + 96 = 0
Solving by factorisation
B² – 10B – 9.6B + 96 = 0
B(B – 10) – 9.6(B – 10) = 0
(B – 9.6)(B – 10) = 0
B – 9.6 = 0 or B – 10 = 0
B = 9.6 or B = 10
Substitute the value of B into equation 3:
L = 19.6 – B
B = 9.6
L = 19.6 – 9.6
L = 10
Or
L = 19.6 – B
B = 10
L = 19.6 – 10
L = 9.6
Since the length is always longer than the breadth,
Length (L) = 10 m
Breadth (B) = 9.6 m
Finally, we shall determine the dimension of the rectangle. This can be obtained as follow:
Length (L) = 10 m
Breadth (B) = 9.6 m
Dimension =?
Dimension = L × B
Dimension = 10 m × 9.6 m
Carl finishes 5kms.Run in 1 hour and 25 minutes.How many minutes did Carl ran?
Answer:
Carl ran for 85 minutes
Step-by-step explanation:
Since we know that he ran for 1 hour and 25 minutes and we know that 1 hour equals 60 minutes we can say that he ran for 60 + 25 minutes. Therefore he ran for 85 minutes.
list all prime numbers between 27 and 35.
Answer:
29 and 31 are the only primes.
The prime numbers that are between 27 and 35 are 29 and 31.
Prime numbers
Prime numbers are those values that can only be divided by 1 and itself (so the result is an integer).
Thus, analyzing all integer values between 27 and 35 we have: 28,29,30,31,32,33,34.
Among these values, the only ones that are not divisible by numbers other than 1 and themselves are 29 and 31.

Show that the area of triangle DEF is 11 cm2.
9514 1404 393
Explanation:
The length CD can be found from the Pythagorean theorem.
CF² + CD² = DF²
2² + CD² = (2√10)²
CD² = 40 -4 = 36
CD = √36 = 6
From here, any of several methods could be used to find the area of ΔDEF.
One of them is to subtract the areas of the triangles that are not ΔDEF from the area of the rectangle ABCD.
area ABCD = bh = (6 cm)(5 cm) = 30 cm²
area ΔADE = 1/2bh = 1/2(4 cm)(5 cm) = 10 cm²
area ΔBEF = 1/2bh = 1/2(2 cm)(3 cm) = 3 cm²
area ΔCDF = 1/2bh = 1/2(6 cm)(2 cm) = 6 cm²
Then the area of interest is ...
area ΔDEF = area ABCD -area ΔADE -area ΔBEF -area ΔCDF
area ΔDEF = (30 -10 -3 -6) cm²
area ΔDEF = 11 cm²
__
Alternate solution
If we define A as the origin of a coordinate system, then the coordinates of the vertices of ΔDEF are ...
D(0, 5), E(4, 0), F(6, 3)
The area can be computed as half the absolute value of the sum of the determinants of 2×2 matrices consisting of adjacent points.
[tex]A=\dfrac{1}{2}\left|\left|\begin{array}{cc}0&5\\4&0\end{array}\right|+\left|\begin{array}{cc}4&0\\6&3\end{array}\right|+\left|\begin{array}{cc}6&3\\0&5\end{array}\right| \right|\\\\=\dfrac{1}{2}|(0-20)+(12-0)+(30-0)|=\dfrac{1}{2}(22) = \boxed{11}[/tex]
_____
Additional comment
The solution using coordinates is effectively equivalent to the computation of the area of trapezoid ABFD, less the areas of triangles EBF and AED.

A plastics company has 75 employees. Management wants to gather data about working conditions. A random sample of 30 employees was selected to receive an anonymous survey. Of those selected, 22 completed the survey. In this scenario, the population is . In this scenario, the sample is .
Answer:
22 completed surveys
Step-by-step explanation:
In the scenario described above, the sample to be used is the information given by the 22 completed surveys. This is because, the remaining 8 initial samples give no information regarding the working condition of employees. Hence, this data points are the null points and may have to be removed from the data.
Therefore, the sample in the scenario described above are the 22 completed surveys from the initial 20 samples selected.
Answer:
1. 75 employees
2. 22 employees

1- mass of earth is 1/95 of the mass of Saturn. if mass of earth is 5.97 x 10^24 kg.find mass of Saturn. show your all work out.
2- write 267000000 in standard form.
3- Maria, Carolina and Pedro receives $1600 from their grandfather in ratio 7:5:4. calculate share of each
Answer:
5.6715 * 10^26 kg
Step-by-step explanation:
Given that :
Mass of earth = 1/95 the mass of saturn
If Mass of earth = 5.97 x 10^24 kg
Let the mass of saturn = x
5.97 x 10^24 kg = 1/95 * x
5.97 x 10^24 kg = x / 95
x = 95 * 5.97 x 10^24 kg
x = 567.15 * 10^24
x = 5.6715 * 10^26 kg
Mass of saturn = 5.6715 * 10^26 kg
