Answers
Answer:
3) 5
4) 8.2
5) 6.8
6)FG = 6.4
7) EF = 3.6
8)DF = 4.8
Step-by-step explanation:
From the attached triangle, using trigonometric ratio we can find ∠G as; tan^(-1) (6/8)
Thus, ∠G = 36.87°
Still using trigonometric ratios;
FG/8 = cos 36.87°
FG = 8 cos 36.87°
FG = 6.4
3) EF + FG = EG
Since EG is 10, mean of EF and FG = 10/2 = 5
4) mean of EG and FG = (10 + 6.4)/2 = 8.2
5) EF + FG = EG
Thus; EF = EG - FG
EF = 10 - 6.4
EF = 3.6
Mean of EG and EF = (10 + 3.6)/2 = 6.8
6) FG = 6.4
7) EF = 3.6
8) Using trigonometric ratio;
DF/8 = sin 36.87
DF = 8 × 0.6
DF = 4.8

O dreaptă (d) și punctele A,B și C în aceasta ordine stind ca AB=10cm; BC=14cm desemnați lungimea segmentului [AC]=? Vă rogg dau coroana!!!!la cine e corect
Answers
Answer:
Length of line AC = 24 cm
Step-by-step explanation:
Given:
Length of line AB = 10 cm
Length of line BC = 14 cm
Find:
Length of line AC
Computation:
We know that line AB and BC are two part of line AC
So,
AC = AB + BC
Length of line AC = Length of line AB + Length of line BC
Length of line AC = 10 + 14
Length of line AC = 24 cm
A positive angle less than 360 degrees that is coterminal with -5 degrees is
Answers
Answer:
[tex]\theta = 355[/tex]
Step-by-step explanation:
Given
Let the angle be [tex]\theta[/tex]
[tex]\theta < 360[/tex]
[tex]\theta[/tex] is co-terminal with -5
Required
Find [tex]\theta[/tex]
Start by dividing 5 by 360 (ignore the negative)
[tex]\frac{5}{360} = 0.0138[/tex]
The nearest integer greater than 0.0138 is 1.
This implies that if you were to draw for this problem, the circle you would draw to show -5 degrees would go around 1 time
So, [tex]\theta[/tex] is calculated as:
[tex]\theta = -5 + 1*360[/tex]
[tex]\theta = -5 +360[/tex]
[tex]\theta = 355[/tex]

Area of the half circle. To get the area of the circle u do radius^2*pi. this will be 2^2*pi in this example. so 4pi. because its half u have to to divide it by 2, so 4pi/2 is 2pi.

Jamie recorded the number of points she scored during her last 5 basketball games. She scored, 15, 25, 10, 2, and 8 points. What is the mean absolute deviation of the points she scored during the last five games?
Answers
Answer:
6.4Step-by-step explanation:
Given scores:
15, 25, 10, 2, and 8Mean of the scores:
(15 + 25 + 10 + 2 + 8)/5 = 12Absolute deviations:
|15 - 12|= 3|25 - 12|= 13|10 - 12| = 2 |2 - 12| = 10|8 - 12| = 4Sum of absolute deviations:
3 + 13 + 2 + 10 + 4 = 32Mean absolute deviation:
32/5 = 6.4total no of game (n)=5
score =15, 25, 10, 2, and 8 points
mean= sum of score/no.of game
=(15+25+10+2+8)/5=60/5=12
absolute deviation of
15=\15-12\=3
25=\25-12\=13
10=\10-12\=2
2=\2-12\=10
8=\8-12\=4
mean absolute deviation=
(3+13+2+10+4)/5=3.6
is the mean absolute deviation of the points she scored during the last five games.

Answers
Answer:

Step-by-step explanation:
We know that ABD is 30 degrees. To find BC, we need to use sin.
Equation:
BC = 16*sin(30 degrees) I recommend using a calculator to find the sine if you don't know what it means and how to use it. Sine is basically the side length opposite of the angle over the hypotenuse of the right triangle.
BC = 16*0.5
BC = 8

c = 27
u = 35
b = 21
plug in the knowns
7x + 3 / 27 = 35 / 21
7x + 3 = 27 ( 35 / 21 )
7x + 3 = 9 ( 35 / 7 ) ( divided by 3 )
7x + 3 = 9 ( 5) ( 7 into 35 =5 )
7x + 3 = 45
7x = 45 - 3

Step-by-step explanation:
David just accepted a job at a new company where he will make an annual salary of $69000. David was told that for each year he stays with the company, he will be given a salary raise of $2500.
This means that after t years, his salary will be given by:
[te]S(t) = 69000 + 2500t[/tex]
How much would David make as a salary after 4 years working for the company?
[te]S(4) = 69000 + 2500*4 = 69000 + 10000 = 79000[/tex]
