Answer:
[tex]\frac{\sqrt{3} }{2}[/tex]
Step-by-step explanation:
Given
sin(- 240°)
To obtain the positive angle measure add 360°, equivalent to one full revolution about the origin, then
ain(- 240°)
= sin(- 240 + 360)°
= sin120°
= sin( 180 - 120)°
= sin60°
= [tex]\frac{\sqrt{3} }{2}[/tex]

Add the correct terms that correspond to the placement.
1. You have $758.12 in your bank account. Free money!
2. You get a job at the CDC on post doing child care. You make $13.20 per hour, and each
week you work for 24.5 hours. How much money do you earn per week?
Answer:
You will earn $323.4 per week
Step-by-step explanation:
We are given:
Cost per hour = $13.20
Number of hours you work each week = 24.5 hours
We need to find how much money do you earn per week.
Amount of money you earned per week = Cost per hour * Number of hours worked
Amount of money you earned per week = 13.20 * 24.5
Amount of money you earned per week = 323.4
So, you will earn $323.4 per week

Miguel and Beth like to play video games together. Miguel has m video games, and Beth has b video games. Miguel has
4 more video games than Beth, and together they have a total of 24 video games. Which system of equations can be
used to find how many video games belong to each friend?
Answer:
Miguel has video games = 14
Beth has video games = 10
Step-by-step explanation:
Miguel has video games = m
Beth has video games = b
We make the equations:
m=b+4 (Miguel has 4 more video games than Beth)
m+b=24 (together they have a total of 24 video games)
So, the system of equations is:
[tex]m=b+4\\m+b=24[/tex]
Now, solving these system of equations to find values of m and b
Let:
[tex]m=b+4--eq(1)\\m+b=24--eq(2)[/tex]
Put value of m from equation 1 into equation 2
[tex]m+b=24\\b+4+b=24\\2b=24-4\\2b=20\\b=\frac{20}{2}\\b=10[/tex]
We get value of b: b=10
Now, finding value of m by putting value of b in equation 1
[tex]m=b+4\\m=10+4\\m=14[/tex]
So, We get value of m: m= 14
Therefore:
Miguel has video games = m = 14
Beth has video games = b = 10
Answer:
m+b=24
m=b+4

- 25
A. 0
O B. 1
C. Infinitely many
SURMIT
Answer:
6x +35 +9x = 15(x+4)
6x +35 +9x = 15x + 60
15x +35 =15x +60
0x= 25
0x= no solution
Step-by-step explanation:
The equation has no solution.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given is an equation, 6x +35 +9x = 15(x+4), we need to find the solution,
6x +35 +9x = 15(x+4)
6x +35 +9x = 15x + 60
15x +35 =15x +60
0 = 25
Since, 0 ≠ 25, this is a contradiction.
Therefore, the equation has no solution.

How to express each of the following pairs of
simultaneous inequalities in the form
a * x * b where a and b are numbers and #
may be < or <,
(a) x > 3, 2x - 3 < 15
(b) 25 > 1 - 6x, 1 > 3x + 7
(c) 2x - 7<3< 27 + 4x
(d) 3x + 8 <0 < 21 + 4x
(e) 5x - 36 < -1 < 2x – 1
Answer:
a) 3<x<8
b) -4<x<-2
c) -6<x<5
d) -21/4 < x-8/3
e) 0<x<7
Step-by-step explanation:
Given the following inequalities
a) x > 3, 2x - 3 < 15
Solve 2x - 3 < 15
2x < 15+3
2x<18
x<18/2
x<8
Combine x>3 and x<8
If x>3, then 3<x
On combining, we have:
3<x<8
b) For the inequalities 25 > 1 - 6x, 1 > 3x + 7
25 > 1 - 6x
25-1>-6x
24>-6x
Divide through by -6:
24/-6 > -6x/-6
-4 <x
For the inequality 1 > 3x + 7
1-7>3x
-6>3x
-6/3 > 3x/3
-2 > x
x < -2
Combining both results i.e -4 <x and x < -2, we will have:
-4<x<-2
c) For the inequalities 2x - 7<3< 27 + 4x
On splitting:
2x - 7<3 and 3< 27 + 4x
2x < 3+7
2x<10
x<5
Also for 3< 27 + 4x
3-27<4x
-24<4x
-24/4 < 4x/4
-6<x
Combining both solutions i.e x<5 and -6<x will give;
-6<x<5
d) For the inequalities 3x + 8 <0 < 21 + 4x
3x + 8 <0
3x < -8
x < -8/3
Also for 0 < 21 + 4x
0-21<4x
-21<4x
-21/4 < 4x/4
-21/4 < x
Combining -21/4 < x and x < -8/3 will give;
-21/4 < x-8/3
e) For the inequalities 5x - 36 < -1 < 2x – 1
Split:
5x - 36 < -1
5x < -1+36
5x<35
5x/5 < 35/5
x < 7
For the expression -1 < 2x – 1
-1+1 < 2x
0 < 2x
0<x
Combining both inequalities 0<x and x < 7 will give:
0<x<7

In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.
Answer:
∠W = 16.3°
Step-by-step explanation:
In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.
From that above question, we are given 3 sides and we are to find the angle of one of the sides.
We solve using Cosine rule.
∠W = arc cos (v² + x²﹣w²/2vx)
∠W = arc cos (64² + 63² - 18² /2 × 64 × 63)
∠W = arc cos (0.9599454365)
∠W = 16.27137°
∠W = 16.3°

for question 8. Determine whether the triangles are similar. If similar, state how (AA, SSS, or SAS), and write a similarity statement.
9514 1404 393
Answer:
yes, SAS
Step-by-step explanation:
Two sides are given, either side of a vertical angle. So, the angles are the same. If the sides are proportional, the similarity will be by SAS (two sides, either side of an angle).
The ratios of short to long sides are ...
39/52 = (3·13)/(4·13) = 3/4
63/84 = (3·21)/(4·21) = 3/4
The sides are proportional and the angle between them is congruent, so ...
the triangles are similar by SAS.

Write in point-slope form the equation of a line that has a slope of -5 and passes through the point (-1, 3).
Answer:
y - 3 = - 5(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 5 and (a, b) = (- 1, 3 ), then
y - 3 = - 5(x - (- 1) ) , that is
y - 3 = - 5(x + 1)
Answer:
Step-by-step explanation:
point slope formula is: y-y1 = m(x-x1) ( memorize this formula there is also slope intercept)
now plug in your point and slope where m = slope and the number of the given point are (x1,y1)
y-3 = -5(x-(-1))
y-3 = -5(x+1)
