At
6:00 A.M. the temperature was 33°F. By noon the temperature had
increased by 10°F and by 3:00 P.M. it had increased another 12°F. If at
10:00 P.M. the temperature had decreased by 15°F, how much does the
temperature need to rise or fall to return to the original temperature
of 33°F?
A)
Fall 7°F
B)
Rise 7°F
C)
Fall 3°F
D)
Rise 3°F
Answers
12:00 p.m. the temperature increased by 10 F so it is 43 F
3:00 p.m. the temperature increased by another 12 F making it 55 F
At 10:00 p.m. it would decrease by 15 F making it 40 F.
The temperature would need to fall/decrease 7 F to reach the original temperature of 33 F so it would be A.

Plot the x- and y-intercepts to graph the equation. y=1/3x−1.
Answers
x-intercept= (3,0)
y-intercept= (0,-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.
Plot these two points (0,-1) and (3,0) on coordinate plane and connect them by a straight line.
explain the. different ways that u can use multiplication to estimate. and solve. division problems
Answers
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

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?
Answers
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.

how many bracelets can she make in 3.5 hours
Answers
If you go to x = 2, you see y = 6.
x is the independent variable and represents the number of hours she works.
Now go up from x = 2 on the x-axis until you reach the line. At that point, y = 6. y is the dependent variable and shows how many bracelets she makes.
She makes 6 bracelets in 2 hours.
If you divide the number of bracelets by the number of hours, you get the unit rate of bracelets per hour.
6 bracelets / 2 hours = 3 bracelets/hour
Now multiply the unit rate by 3.5 hours
3 bracelets / hour * 3.5 hours = 10.5 bracelets.
In 3.5 hours, she makes 10.5 bracelets.
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 ?
Answers
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.

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?
Answers
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.

An architect is designing a new windmill with four sails. In his sketch the sails center of rotation is the origin (0,0) and the top of one sails point T, has a coordinates (6,-2). He wants to make another sketch that shows the windmill after sails have rotated 180* degrees about their center of rotation. What would be the coordinates of T?
Answers
The coordinates of T are (-6,2).
The sails center of rotation is the origin (0,0)
The top of one sails point T(6,2).
What is the rotation?The action or process of rotating on or as if on an axis or center.
A 180 degree rotation make you turn (x, y) into (-x, -y),
so the point turn (6, -2), into (-6, 2).
Therefore the coordinates of T are (-6,2).
