Answer:
x/2-10=18
Step-by-step explanation:
An equation is formed of two equal expressions. The given statement The quotient of a number and -2, less 10, is -18 can be written as an equation as (x/-2)-10=-18.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number be represented by x. Therefore, the given statement can be written as,
(x/-2)-10=-18
Hence, the given statement The quotient of a number and -2, less 10, is -18 can be written as an equation as (x/-2)-10=-18.

B.
B.120
C.
130
D.
140
120l NaBr solute is saturated at 70 degrees. In this case option b is correct when saturated at 70 degrees.
NaBr is the chemical formula for sodium bromide. It is an inorganic compound composed of sodium (Na) and bromine (Br). Sodium bromide is a white, crystalline solid that is highly soluble in water.
In terms of its properties and uses, sodium bromide has various applications. It is commonly used in the pharmaceutical industry as a sedative and anticonvulsant drug. Sodium bromide is also used in the oil and gas industry as a completion fluid in well drilling and workover operations. Additionally, it finds applications in photography as a component of some film developers.
As a salt, sodium bromide dissociates into sodium ions (Na+) and bromide ions (Br-) when dissolved in water. These ions can participate in various chemical reactions and have different effects depending on the specific application or purpose.

Find the measure of the angle indicated... please help
Answer:
Step-by-step explanation:
41). Measure of an external angle of a triangle is equal to the sum of teh opposite two angles.
140° = (13x + 9)° + (5x + 5)°
140 = 18x + 14
18x = 140 - 14
18x = 126
x = 7
m∠R = (13x + 9)
= 13×7 + 9
= 100°
42). m∠DCA = m∠E + m∠D
126° = (6x + 2)° + (5x + 3)°
126 = 11x + 5
11x = 126 - 5
11x = 121
x = 11
m∠D = (5x + 3)
= 5(11) + 3
= 58°
43). m∠DPQ = m∠Q + m∠R
11x + 3 = 70° + (x + 13)°
11x + 3 = x + 83
11x - x = 83 - 3
10x = 80
x = 8
m∠R = (x + 13)
= 21°
44). m∠QST = m∠T + m∠U
13 + 13x = 100 + (3x + 3)
13 + 13x = 3x + 103
13x - 3x = 103 - 13
10x = 90
x = 9
m∠U = 3x + 3
= 3(9) + 3
= 27 + 3
= 30°

Answer:
First box: 1
Second box: 110
Third box: 2
Step-by-step explanation:
Any number divided by itself is 1. So, 65 divided by 65 = 1
Any number multiplied by 1 is the same number. So, 1 x 110 = 110
Or, you can simply do 65 times 2 to get 110

The angle 01 is located in Quadrant IV, and sin(01) = -24/ 25
What is the value of cos(01)?
Answer:
[tex] \frac{7}{25} [/tex]
Step-by-step explanation:
We can solve that using this identity,
[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]
plug in -24/25 from x in sin
[tex] \sin {}^{2} ( \frac{ - 24}{25} ) + \cos {}^{2} (x) = 1[/tex]
[tex] \sin( \frac{576}{625} ) + \cos {}^{2} (x) = 1[/tex]
[tex] \cos {}^{2} (x) = 1 - \frac{576}{625} [/tex]
[tex] \cos {}^{2} (x) = \frac{49}{625} [/tex]
[tex] \cos(x) = \frac{7}{25} [/tex]
Since cos is positve in quadrant 4, the answer is 7/25.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
then
Sin(Ф) = - [tex]\frac{24}{25}[/tex]
find the angle Ф
Ф = arcSin ( - [tex]\frac{24}{25}[/tex] )
Ф = -73.739795°
so an angle measured clock wise from x axis at zero°
now use cos(Ф) = x/ 25 to find x
25* cos( -73.739795°) = x
7 = x :o wow... exactly? :P nice
cos(Ф) = 7/25 I think that's what they wanted to know
also I noted my calculator tried to find the fraction of 0.2800000049 and couldn't, but then I just put in 0.28 and it found that to be 7/25 :0 so I think we're spot on :)

Steve connected a wire extension that is 3/8 foot long to another wire that is 1/2 foot long. How long is the wire with the extension?
Answer:
7/8 feet
Step-by-step explanation:
In order to add two frctions you need to make their denominator the same,
3/8 can be kept as it is and we can multiply the top and bottom of 1/2 by 4 in order to ger 4/8. Now it is easier to add together,
3/8 + 4/8= 7/8
