Answer:
The number is either 95 or 59
Step-by-step explanation:
The two digit number would be;
(10a + b)
The reversal will be (10b + a)
The sum of the two is 154
(10a + b ) + (10b + a) = 154
11a + 11b = 154
11(a + b) = 154
a + b = 14 ••••••••(i)
The difference between the two digits is 4
Let’s have this as;
a - b = 4 ••••(ii)
from ii;
a = 4 + b
Substitute this into equation i
4 + b + b = 14
2b = 14-4
2b = 10
b = 10/2
b = 5
Recall;
a = b + 4
a = 5 + 4
a = 9
So we have the number as 95 or 59

A circle is to be cut from a 12 ft square board. What will be the area, in square feet, of the inscribed circle? Leave your answer in terms of π.
Answer:
3π sq.feet
Step-by-step explanation:
Area of the square = L²
L is the length of the square
Given
Area of the square = 12 ft square
12 = L²
L = √12
L = 2√3 feet
Since the circle is inscribed in the square, the length of the square will be the diameter of the circle;
Area of the circle = πd²/4
Area of the circle = π(2√3)²/4
Area of the circle = 12π/4
Area of the circle = 3π sq.feet
A linear equation, in terms of x, is correctly solved. The final step in the solution process shows that there are infinitely many solutions of the equation. Which could be the final step? A. x = 0
В. 312 = 427
C. 5,678 = 5,678
D. x = 100,000,000
Answer:
C)
Step-by-step explanation:
infinite number of solutions means the left side equals the right side of the equation
no solution means the left side does not equal the right side
x = {whatever} means there is one solution

c.
negative relationship, linear
d.
no relationship
Answer:
B. Positive relationship, linear
General Formulas and Concepts:
Statistics
Trends
Positive Correlation - data is increasingNegative Correlation - data is decreasingNo Correlation - data is scatteredStep-by-step explanation:
According to the given graph, we see that our data is increasing. Therefore, there will be a positive relationship in the graph.
∴ Answers C and D are eliminated.
We also see that we can draw a best line of fit in the graph. Since we can approximate this data using a linear line, our answer choice would be B.

the perimeter of an equalatrial triangle is 45m.what is the length of one side
Answer:
The length of one side is 15 cm
Step-by-step explanation:
In an equilateral triangle
perimeter (p) = 45 m
As we know that all three sides are equal in an equilateral triangle so, Let the length be l then
3l = p
3l = 45
l = 15 cm

The equation y = -20x + 275 represents the balance of Cassie's bank account y after x months. Which of the following statements regarding Cassie's account is not true?
The rate of change of the function is the slope of the line, -20.
The rate of change of the function is the slope of the line, -20.
The initial value of the function is the y-intercept of the line, 275.
The initial value of the function is the y-intercept of the line, 275.
Initially, Cassie has $20 in her account.
Initially, Cassie has $20 in her account.
Each month after the initial month, Cassie withdraws $20 from the account.
Please help
Answer: The answer that is false is “Initially, Cassie has $20 dollars in her account.”
Step-by-step explanation: The reason why this is false is because the first statement that the slope of the line is -20 is true. The formula for slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Next the initial value is 275 because in these problems the y-intercept is technically the starting value in these problems. So since the initial value is 275 the last statement is false.
