B. making a note of each expense so that she does not repeat purchases
C. preparing a report for her bank on how she spends money
D. preparing a budget to review her expenses
Answer:
D is the right answer.
Step-by-step explanation:
Given that Sarah used to maintain a log of each time she spends or receives money.
Logs are maintained normally for money receipt and payment for the following reasons.
i) To know accurate the cash balance in hand at any time
ii) To estimate the purchases still due
iii) to plan for utilizing the available money for effective uses,
iv) to prepare a budget to review her expenses
Out of the four options the last option seems to be more appropriate for this.
b. The square is inscribed within the circle?
Answer:
a. 20π cm.
b. 20(√2)π cm,
Step-by-step explanation:
a. The diameter (d) of the circle = side of the square = 20 cm.
So the circumference = π d = 20π cm.
b. In this case the diameter = the length of the diagonal of the square.
The diagonal = diameter of the circle =sqrt ( 20^2 + 20^2) = √800 = 20√2.
So the circumference = πd = 20(√2)π.

Formula: P(A or B)=P(A)+P(B)-P(A or B)
p(c)=7/18
p(s)=6/18
p(c or s)=2/18
0.39+0.33-0.11=
answer:0.61

The relationship between Speed, Distance and Time can be expressed as:
The total distance to be covered is 96 kilometres. Ashley couldn't cover it with existing speed and in available time.
Given:
Now, calculate the maximum distance that is possible to cover.
The total distance to be covered by her is 96 kilometres. Ashley could cover only 90 kilometres.

Answer:
-8 is the answer.
Step-by-step explanation:
Move -2 steps (i.e. move two steps to the left) four times. You jump into these numbers.
-2, then -4, then -6, then finally -8.

Step-by-step explanation:
To determine which system has x = 3 and y = 2.5 as its solution, we need to substitute these values into each system of equations and check which one satisfies the conditions.
System 1: 7x - 5y = 33.5
Substituting x = 3 and y = 2.5:
7(3) - 5(2.5) = 21 - 12.5 = 8.5
System 2: 3x + 3y = 1.5
Substituting x = 3 and y = 2.5:
3(3) + 3(2.5) = 9 + 7.5 = 16.5
System 3: 4x + y = 9.5
Substituting x = 3 and y = 2.5:
4(3) + 2.5 = 12 + 2.5 = 14.5
System 4: 5x - y = 12.5
Substituting x = 3 and y = 2.5:
5(3) - 2.5 = 15 - 2.5 = 12.5
System 5: 2x - 5y = 18.5
Substituting x = 3 and y = 2.5:
2(3) - 5(2.5) = 6 - 12.5 = -6.5
System 6: x + y = 5.5
Substituting x = 3 and y = 2.5:
3 + 2.5 = 5.5
System 7: 11x + 10y = 8
Substituting x = 3 and y = 2.5:
11(3) + 10(2.5) = 33 + 25 = 58
System 8: 5x - 2y = -20
Substituting x = 3 and y = 2.5:
5(3) - 2(2.5) = 15 - 5 = 10
From the calculations, we can see that only System 4: 5x - y = 12.5 satisfies the given conditions when x = 3 and y = 2.5. Therefore, the correct answer is System 4.
