Answer:
Instead of divide the dividend by the divisor to get a quotient, you can estimate an approximate quotient and then multiply it by the dividend. If the result is greater than the divisor, then your estimated quotient was greater than the actual quotient, in the case that the result is lower than the divisor, then your estimated quotient was lower than the actual quotient. After that you proceed to estimate again the quotient. For example:
First approximation:
192/12 ≈ 14
12*14 = 168 < 192
Second approximation:
192/12 ≈ 20
12*20 = 240
So, the answer is between 14 and 20
Third approximation:
192/12 ≈ 16
12*16 = 192
Then, 16 is the correct answer

What is the slope of the line passing through the points (-1,3) and (4,-7)?
A. 2
B. -2
C. 3/4
D. - 4/3
Answer:
B) -2
Step-by-step explanation:
-7-3/ 4+1= -10/5 = -2
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (-1, 3) and (4, -7). Substitute:
[tex]m=\dfrac{-7-3}{4-(-1)}=\dfrac{-10}{5}=\boxed{-2}\to\boxed{B.}[/tex]

Kendrick adds 3/4cup of chicken stock to a pot. Then he takes 3/4 cup of stock out of the pot. What is the overall increase or decrease in the amount of chicken stock in the pot?
There is no net change in the amount of chicken stock in the pot.
To determine the overall change in the amount of chicken stock, we need to compare the amount added to the amount removed. Kendrick adds 3/4 cup of chicken stock to the pot, and then he takes out 3/4 cup of chicken stock from the pot.
Using a simple calculation:
Initial stock added: 3/4 cupStock removed: 3/4 cupOverall change = 3/4 cup - 3/4 cup = 0 cupsTherefore, the overall increase or decrease in the amount of chicken stock in the pot is zero. There is no net change in the amount of chicken stock in the pot.

jacob bought some tickets to see his favorite singer. He bought some adult tickets and some children's tickets, for a total of 9 tickets. The adult tickets cost $10 per ticket, and the children's tickets cost $8 per ticket. If he spent a total of $76, then how many adult and children's tickets did he buy ?
Final answer:
Jacob bought 2 adult tickets and 7 children's tickets to see his favorite singer, spending a total of $76 for 9 tickets with adult tickets costing $10 each and children's tickets $8 each.
Explanation:
Jacob bought a total of 9 tickets, consisting of adult tickets and children's tickets. Adult tickets cost $10 each while children's tickets cost $8 each, and Jacob spent a total of $76 on tickets. To find out the number of adult and children's tickets he bought, we can set up a system of equations:
Let the number of adult tickets be represented by a and the number of children's tickets be represented by c. We are given two pieces of information:
Jacob bought 9 tickets in total: a + c = 9The total amount spent was $76: 10a + 8c = 76We can solve the system of equations by substitution or elimination. If we rearrange the first equation (a + c = 9) to get a = 9 - c, we can substitute this into the second equation 10a + 8c = 76:
10(9 - c) + 8c = 7690 - 10c + 8c = 7690 - 2c = 762c = 14c = 7Now that we have the value for c, we can find a:
a = 9 - ca = 9 - 7a = 2Jacob bought 2 adult tickets and 7 children's tickets.

Jennifer can paddle a certain distance with the current in 2.5 hr. To cover the same distance against the current, she takes 5 hr. How many times faster is her rate of paddling in still water than the speed of the current?
The rate of paddling in still water is 3 times than the speed of the current.
What is Speed?
The formula for the speed is calculated as;
Speed = Distance / Time
Given that;
Jennifer can paddle a certain distance with the current in 2.5 hr.
And, To cover the same distance against the current, she takes 5 hr.
Let distance be D , speed is S and the current speed will be C.
The we can formulate two conditions as;
(S + C) × 2.5 = D .... (I)
And, (S - C) × 5 = D .... (II)
Solve equation (i) and (ii) we get;
S = 3C
Thus, we can say that;
The rate of paddling in still water is 3 times than the speed of the current.

the area of australia is 2.95 x 10^6 square miles. what's the approximate average number of people per square mile in Australia?
The approximate average number of people per square mile in Australia is approximately 8.47.
Explanation:To find the approximate average number of people per square mile in Australia, we can divide the total population of Australia by the area in square miles. According to the Australian Bureau of Statistics, the population of Australia is approximately 25 million. To calculate the average number of people per square mile, we can divide 25 million by 2.95 x 10^6:
Average number of people per square mile = 25,000,000 / 2.95 x 10^6
Simplifying this expression, we get:
Average number of people per square mile ≈ 8.47
Therefore, the approximate average number of people per square mile in Australia is approximately 8.47.

Plot the x- and y-intercepts to graph the equation. y=1/3x−1.
Answer:
The graph of given equation is shown below.
x-intercept is 3 and y-intercept is -1.
Step-by-step explanation:
The given function is
[tex]f(x)=\frac{1}{3}x-1[/tex]
We need to draw the graph of given equation.
At x=0,
[tex]f(0)=\frac{1}{3}(0)-1=-1[/tex]
So, y-intercept is -1.
Equate f(x)=0 to find x-intercept.
[tex]\frac{1}{3}x-1=0[/tex]
[tex]\frac{1}{3}x=1[/tex]
Multiply both sides by 3.
[tex]x=3[/tex]
So, x-intercept of the line is 3.
