Answer:
15%
Step-by-step explanation:
GIven data
Initial population= 354,000
Final population=407,100
%Error= Final- Initial/initia*100
%Error= 407,100- 354,000/ 354,000*100
%Error= 53100/ 354,000*100
%Error=0.15*100
%Error=15%
Hence the error is 15%

Which of the following expressions cannot be written as an integer?

1.2 x 102
149
Answer:
1.2 x 102
Step-by-step explanation:
An integer is an whole number. It is not a fraction or a decimal.
Types of Integers
1. Positive integers e.g. 18, 3, 149
2. Negative integers e.g. -30
3. Zero integers e.g. 0
1.2 x 102 = 122.4. 122.4 is not an integer because it is not a whole number
Write the equation of this circle in standard form. A) (x - 2)2 + (y - 3)2 = 4 B) (x + 2)2 + (y + 3)2 = 4 (x - 2)2 + (y - 3)2 = 16 D) (x + 2)2 + (y + 3)2 = 16
Answer:
The answer is C.
Step-by-step explanation:
The equation of the circle (x - 2)² + (y - 3)² = 16 if the center of the circle is (2, 3) and the radius is 4 units option (C) is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The graph of the circle is given in the picture:
The center of the circle is (2, 3) and the radius of the circle is 4 units
As we know, the standard equation of the circle is:
(x - h)² + (y - k)² = r²
Here (h, k) and r is the center of the circle and the radius of the circle.
h = 2 and k = 3
r = 4 plug all the values in the equation:
(x - 2)² + (y - 3)² = 4²
(x - 2)² + (y - 3)² = 16
Thus, the equation of the circle (x - 2)² + (y - 3)² = 16 if the center of the circle is (2, 3) and the radius is 4 units option (C) is correct.

What is the value of x in the equation 2.5(6x - 4) = 10 + 4(1.5 +0.5 x)?
3
이를
02
0 13
Answer:
Step-by-step explanation:
15x - 10 = 10 + 6 + 2x
15x - 10 = 16 + 2x
Bringing like terms on one side
15x - 2x = 16 + 10
13x = 26
x = 26/13
x = 2
The value of x in the equation is 2.
Option C is the correct answer.
What is an equation?An equation is a mathematical statement that shows that two expressions are equal.
It consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. Equations are used to solve problems and find unknown values.
We have,
We are given the equation 2.5(6x - 4) = 10 + 4(1.5 + 0.5x) and we need to find the value of x that satisfies this equation.
First, we can simplify both sides of the equation by using the distributive property of multiplication.
This gives us:
15x - 10 = 10 + 6 + 2x
Next, we can combine like terms on both sides of the equation. Specifically, we can combine the constants on the right-hand side:
15x - 10 = 16 + 2x
Now, we want to isolate the term with x on one side of the equation.
We can do this by subtracting 2x from both sides of the equation:
13x - 10 = 16
Finally, we can solve for x by adding 10 to both sides of the equation and then dividing both sides by 13:
13x = 26
x = 2
Therefore,
The value of x in the equation is 2.

twice a number when described by 7 gives 45 . find the number. and also who wants to talk im bored
Answer:
Answer
Let the number be x.
twice =2x
When it is decreased by 7 we get the following equation:
2x−7=45
⇒2x=45+7
⇒2x=52
⇒x=252
∴x=26
The number is 26.

Martha rented a sedan at a cost of $21.25 a day for three days. She drove 980 miles at 25 cents a mile. Gas cost $63.45 what was the cost per mile
Answer:
38 cents per mile
Step-by-step explanation:
Let us first calculate the total expenditure by Martha
= 21.25*3= $ 63.75
Cost of gas =$ 63.45
Therefore cost per mile = 127.2/980= 0.1297+0.25= $0.3797 or 38 cents per mile
