Centerpoint Energy charges a service fee of $4.95 plus $0.16 per Kilowatt hour (kWh) usage. Which equation can be used to find y, the total cost of the electric bill, if x represents the kWh usage?
a. y = 0.16x
b. y = 0.16 + 4.95x
c.y = 4.95 + 0.16x
d. y = 0.16(x + 4.95)
1kg petrol has density of 800kg/m3 find its volume in cm 3
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
In 2000, the world population was 6.1 billion. In 2015, the world population was 7.3 billion. Work out the percentage increase in population. Give your answer correct to 1 decimal place.
Answer:
19.7%
Step-by-step explanation:
Given that,
In 2000, the world population was 6.1 billion.
In 2015, the world population was 7.3 billion.
We need to find the percentage increase in population. The percent increase in this case is given by :
[tex]\%=\dfrac{7.3-6.1}{6.1}\times 100\\\\=19.67\%\\\\=19.7\%[/tex]
So, the increase in population is 19.7%.

Step-by-step explanation:
In mathematics, a rational number is a number such as -3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Every integer is a rational number: for example, 5 = 5/1.

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°

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!

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

Part A: Which of the following statements would be TRUE?
A.
The x-intercepts of the function are 0 and 8, which are a lower bound and an upper bound for the possible values of the length of the storage bin.
B.
The x-intercepts of the function are 0 and 18, which are a lower bound and an upper bound for the possible values of the length of the storage bin.
C.
The x-intercepts of the function are 0 and 8, which are a lower bound and an upper bound for the possible values of the width of the storage bin.
D.
The x-intercepts of the function are 0 and 18, which are a lower bound and an upper bound for the possible values of the width of the storage bin.

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
