Let
y ----> total charge in a month
x ----> number of minutes
so
Plan A
y=0.21x+11
Plan B
y=0.10x+20
Equate both equations
0.21x+11=0.10x+20
solve for x
0.21x-0.10x=20-11
0.11x=9
x=9/0.11
x=81.82 minutes
Convert to hours and minutes
81.82 minutes=60+21.82=1 hour 22 min
therefore
the answer is option ACO2 How many atoms of each element are in the formula shown?
The number of atoms of each element in CO2 are; Number of O atoms = 2 and Number of C atoms = 1
What is the number of atoms present in the element?The number of atoms present in the molecule of an element is known as its Atomicity. For Example: In the H2O molecule, its atomicity is 3 as it has 2 molecules of hydrogen and 1 molecule of oxygen
Similarly, for the antiperspirant Al₂Cl(OH)₅. the number of atoms in each element can be found as follows;
Number of Al atoms = 2
Number of Cl atoms = 1
Number of H atoms = 1 x 5 = 5
Number of O atoms = 1 x 5 = 5
Applying the above to our question gives;
Number of C atoms = 1 atom
Number of O atoms = 2 Atoms

1. The total bill that the basketball team will pay is $165.
2. The change that the person will recieve after paying is $43.075
How to calculate the value?1. The basketball team went out and the total bill was $125.
Tip given to waitress= 25% = 25% × $125 = $31.25
Tax rate = 7% = 7% × $125 = $8.75
Total bill = $125 + $31.25 + $8.75 = $165
2. Amount saved = $100
Total bill = $45
Tip given to waitress= 20% = 20% × $45 = $9
Tax rate = 6.5% = 6.5% × $45 = $2.925
Amount left = $100 - $45 - $9 - $2.925 = $43.075

What is the slope of this graph? 1/4 -4 -1/4 -4
Answer:
-4
Step-by-step explanation:
The line goes down as it moves to the right so it has to be negative.
It goes over 1 and down 4.
To find the slope we use -4/1
We do this because it went down 4 so the 4 is negative, and we use 1 because it went over 1.
So -4/1 = -4
When solved for C, the equation is
C = K – 273.15
C = 273.15 – K
C = K + 273.15
C = 273.15K
The temperature in Celsius (C) increased by 273.15 to get the temperature in Kelvin (K). The equation with the subject Celsius (C) is C=K-273.15, Option A correct.
Given that,
The temperature in Celsius (C) increased by 273.15 to get the temperature in Kelvin (K).
The formula K = C + 273.15 can be used to simulate this.
We have to find the equation with the subject C.
K=C+273.15
Taking the C to left hand side and K to right hand side.
-C=273.15-K
Multiplying -1 on both sides
-1(-C)=-1(273.15-K)
C=K-273.15
Therefore, The equation with the subject Celsius (C) is C=K-273.15, Option A correct.

jack strong has $50,000 of wealth. he is participating in a jujitsu competition. the prize is $10,000. he is guaranteed to win it (he has black belt) unless he breaks his arm. if his arm is broken, he will lose the tournament and he will have to pay $5,000 in medical expenses. jack thinks that the probability of him breaking his arm during a tournament is 5 percent. he can get a medical insurance at a price of $.3 dollars for each $1 of coverage.
He’ll get the prize of dollar 10000, then the consumption after adding dollar 1500 is: $10000 + $1500 = $11500
a) the derive equation is 50000 + 10000 + x
jack has maximum amount of wealth = $50,000
When he participated in a jujitsu competition then the prize amount = 10,000
Then we will take a variable x for derive the equation which will depend on that he will win and loose :
Here,
the equation is = 50000 + 10000 + x
b) His consumption after not purchasing medical insurance is $15000.
if, he does not purchase medical insurance then he has no coverage of insurance and
He’ll lose the tournament and he’ll have to pay medical expenses dollar 5000 and also the prize amount $10000
So, his consumption after not purchasing medical insurance is:
$10000 + $5000 = $15000
c) when he will purchase medical insurance then his total consumption is $3500
his consumption if he purchase medical insurance, he will give dollar1 for medical insurance and will get in return dollar .3 ,
When he will have to pay for medical insurance $5000, then he’ll get the coverage on medical insurance:
0.3 * 5000 = $1500
Now, subtracting the amount of medical insurance which he’ll have to pay:
$5000 - $1500 = $3500
He’ll get the prize of dollar 10000, then the consumption after adding dollar 1500 is:
$10000 + $1500 = $11500

a 1 =49 a i =a i−1 −3 Find the sum of the first 26 terms in the sequence.
By using the concepts of recurrence formula and sum, the sum of the first 26 terms of the sequence is equal to 299.
How to determine the sum of the sequence with the help of recurrence formulas
In this problem we have a recurrence formula of the following form: a₁ = C and aₙ = aₙ₋₁ + k. Then, the sum of first n terms of the sequence is:
s = a₁ + a₂ + a₃ + ... + aₙ₋₁ + aₙ
First, determine the first 26 terms of the series:
a₁ = 49
a₂ = 46
a₃ = 43
a₄ = 40
a₅ = 37
a₆ = 34
a₇ = 31
a₈ = 28
a₉ = 25
a₁₀ = 22
a₁₁ = 19
a₁₂ = 16
a₁₃ = 13
a₁₄ = 10
a₁₅ = 7
a₁₆ = 4
a₁₇ = 1
a₁₈ = - 2
a₁₉ = - 5
a₂₀ = - 8
a₂₁ = - 11
a₂₂ = - 14
a₂₃ = - 17
a₂₄ = - 20
a₂₅ = - 23
a₂₆ = - 26
Second, sum all the terms found in the previous step:
s = 49 + 46 + 43 + 40 + 37 + 34 + 31 + 28 + 25 + 22 + 19 + 16 + 13 + 10 + 7 + 4 + 1 - 2 - 5 - 8 - 11 - 14 - 17 - 20 - 23 - 26
s = 299

Find the measure of angle TRS.
The measure of the angle TRS = 46°
The angles given in figure are :
angle QSR = 110°
angle STR = 64°
angle QRS = 2x-10°
We will find the angle TRS using these given angles and some angle properties in a triangle.
We have the fact that sum of three angles of a triangle = 180°
So angle TRS + angle RST + angle STR = 180°
angle QSR and angle RST are supplementary. i.e., their sum = 180°
So angle RST = 180° - 110° = 70°
So angle TRS = 180°- (70°+64°) = 46°
Using angle TRS we can also find angle QRS and thereby, the value of x.
From the figure, angle QRT = 90°.
So angle QRS = 90°-angle TRS
⇒ 2x - 10° = 90° - 46°
⇒ 2x = 44° + 10°
⇒ x = 54°/2
⇒ x = 27°

describe fully the single transformation which takes shape A to shape B .
please help me !!
The single transformation from shape A to shape B is;
(1, 6); (x, y) → (y + 1, x + 5)
(5, 6); (x, y) → (y + 1, x - 3)
(3, 8); (x, y) → (y + 1, x + 1)
How to find the transformation?We know that in transformation, it could either be a reflection, a dilation, a translation e.t.c.
Now, let us look at the shapes A and B to find their coordinates.
Coordinates of Shape A are; (1, 6), (5, 6), (3, 8)
Coordinates of Shape B are; (7, 6), (7, 2), (9, 4)
Since the transformed shape B is to the right of the original shape A, then we can suggest that the first transformation is a reflection about the line x = 6. Thus, this is; (x, y) → (y, x)
The transformation of shape A following (x, y) → (y, x) is;
A'(6, 1), B'(6, 5), C'(8, 3)
Comparing that to the coordinates of shape B, we can say that the transformations are;
(1, 6); (x, y) → (y + 1, x + 5)
(5, 6); (x, y) → (y + 1, x - 3)
(3, 8); (x, y) → (y + 1, x + 1)
