In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.
Answer:
The possible values for ∠V is 81.2° and 98.8°
Step-by-step explanation:
In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.
We solve the above question using Sine rule
Sine rule
= u/sin U = v/sin V
In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°
Hence:
7.6/sin 68° = 8.1/sin V
Cross Multiply
7.6 × sin V = sin 68° × 8.1
sin V = sin 68° × 8.1/7.6
V = arc sin ( sin 68° × 8.1/7.6)
V = arc sin (0.99)
V = 81.18°
Another value for V = 180° - 81.18°
= 98.82°
Therefore, the possible values for ∠V approximately to the nearest tenth of a degree is 81.2° and 98.8°

On Saturdays. Eve earns $14 per hour for yard work and charges an extra amount for supplies/gas money to get there. Look at the table. Choose the linear function f Eve can use to determine her pay, where x is in hours and f(x) is her pay in dollars.
Hours 1 2 3 4 5
Pay 26 40 54 68 82
A f(x) = x + 14
B. f(x) = 12x + 16
C. f(x) = 12x + 14
D. f(x) = 14x + 12
Answer:
D
Step-by-step explanation:
Question:On Saturdays. Eve earns $14. per hour for yard work and charges an extra amount for supplies/gas money to get there. Look at the table. Choose the linear function f Eve can use to determine her pay, where x is in hours and f(x) is her pay in dollars.
Answer: The answer would be D because she gets payed $14 and hour so you would plug the hours she work into the letter x.

Why is graphing the best method to solve the following system of equations?
y= 3x + 1
y=x+5
Answer:
because all the numbers used are whole numbers and as a result will appear clearly on a graph. if there were decimals you would need to estimate and the answer would not be accurate

Please help me with this x+125+d=1,245
Answer:
x=1120-d
Step-by-step explanation:
Answer:
x = 1120 - d
Step-by-step explanation:
Hi there!
We can simplify this using orders of operations.
First, subtract 125 from both sides to get x + d = 1120.
To isolate x, just subtract d from both sides.
If you give me a value for d, i can solve the full problem.
I hope this helps!
Let's compare 7/9 and 5/6. First, write the fractions with the same denominator. 7/9 = 5/6= Then, use <, =, or > to compare the fractions. 7/9 5/6
Answer:
7/9 < 5/6
Step-by-step explanation:
The denominator is the common factor of the denominators
That is 54
So we have
7/9 * 6/6 = 42/54
5/6 * 9/9 = 45/54
So, the relation we have is that;
7/9 < 5/6
Need help bro geometry aint it
Answer:
∠CAD = 44⁰
∠ACD = 44⁰
∠ACB = 136⁰
∠ABC = 22⁰
Step-by-step explanation:
To calculate m∠CAD;
Line AD = Line DC,
thus ∠CAD = ∠ACD = ¹/₂(180 - 92°) [sum of angles in a triangle.]
∠CAD = ¹/₂ x 88 = 44⁰
Also, ∠ACD = 44⁰
To calculate m∠ACB;
∠ACB = 180 - ∠ACD [Sum of angles on a straight line]
∠ACB = 180 - 44
∠ACB = 136⁰
To calculate m∠ABC;
Line CB = Line CA
Thus, ∠ABC = ∠CAB = ¹/₂(180 - ∠ACB) [sum of angles in a triangle.]
∠ABC = ¹/₂(180 - 136)
∠ABC = ¹/₂ x 44
∠ABC = 22⁰

Answer:
1.25*10-3m^3
Step-by-step explanation:
1kg petrol has density of 800kg/m3 find its volume in cm 3
Given data
mass m= 1kg
density = 800kg/m3
Required
The volume v
We know that
density= mass/volume
so
Volume= mass/density
substute
Volume= 1/800
volume=1.25*10-3m^3
Hence the volume is 1.25*10-3m^3
