Answer:
Put the arrow on -1.3.
Step-by-step explanation:
In order to find -1.3, we first have to solve the problem.
-2 - (-0.7)
Since negative - negative = negative, we know our answer is already going to be negative.
Subtract -0.7 from -2, and to make it easier you can do it on a calculator if you want.
First remove the brackets, then turn the negative sign on -0.7 and the minus sign into a plus sign. It will turn into:
-2 + 0.7
When you add, 0.7 to -2, the sum is -1.3.
Therefore you mark the arrow on -1.3

Find the approximate radius of a circle with a circumference of 2 kilometers. Use 3.14 for π. Round to the nearest hundredth if necessary.
Answers
Answer:
0.32 (rounded to the nearest hundredth)
Step-by-step explanation:
If you have any questions ask me please! :)
Answer:
0.32 km
Step-by-step explanation:
Using the formula r = c / (2 * π), where c = 2 kilometers and π = 3.14, we can calculate the radius as:
r = 2 km / (2 * 3.14)
r = 2 km / 6.28
r = 0.31847133758 km
Rounding this to the nearest hundredth gives:r ≈ 0.32 km
Therefore, the approximate radius of the circle is 0.32 kilometers.
Mr. Walker brought 100 cookies for two classes at school one class had 28 students, and the other had 27 students plus their two teachers. he also left 10 for the office staff and 5 for the custodians. How many cookies did he have leftover?
Answers
Answer:
Mr. Walker gave out a total of 28 + 27 + 2 = 57 cookies to the two classes and left 10 + 5 = 15 cookies for the office staff and custodians.
Therefore, the number of cookies left over is:
100 - 57 - 15 = 28 cookies
Mr. Walker had 28 cookies left over.
Step-by-step explanation:
Answer: 28 cookies
Step-by-step explanation:
We have to add up the number of cookies distributed and subtract it from the total amount of cookies he brought in order to find out how many cookies he has left over.
----------------------------------------------------------------------------------------------------------
First classFor the first class with 28 students, Mr. Walker distributed 28 cookies.
----------------------------------------------------------------------------------------------------------
Second ClassThere are 29 people in the second class, which has 27 students and 2 teachers.
Mr. Walker then gave out 29 cookies.
----------------------------------------------------------------------------------------------------------
Office Staff and CustodiansMr. Walker left 10 for the office staff, 5 for the custodians, which is a total of 10 + 5 = 15.
So, Mr. Walker distributed 15 cookies.
----------------------------------------------------------------------------------------------------------
Finding the answerWe add up the number of cookies distributed to figure out how many cookies he had leftover:
28 + 29 + 15 = 72.
This gets subtracted from the total number of cookies brought by him:
100 - 72 = 28.
----------------------------------------------------------------------------------------------------------
AnswerTherefore, after giving cookies to the two classes, the office staff, and the custodians, Mr. Walker had 28 cookies left over.

Answer:
Equation: x=45,000 ÷ 3
Answer: 15,000
Step-by-step explanation:
We know that 2/3 of the pens produced in the factory are black. That means that 1/3 of the pens produced in the factory are blue.
If 45,000 pens are produced, then 1/3 of 45,000 will give us the number of blue pens, or x. Now with our equation, we can start solving.
x = 45,000(1/3) is the same thing as x = 45,000 ÷ 3.
45 ÷ 3 is 15. Now we can just add the zeros back in.
x=15000
Therefore, the number of blue pens, or x, is 15,000.

Answer:
7 juniors and 2 coins
Step-by-step explanation:
25% is equal to 25/100 which is 1/4. To find 1/4 of 28 it would be 28/4 which is 7. There are 7 juniors in the program.
5-cent: x
10-cent: y
25-cent: z
5x+10y+25z=320 which is also x+2y=5z=64. You can subsitute y for x+3 because he has 3 more 10-cent than 5-cent. x+x+3+z=23 which is 2x+z=20=z=20-2x.
Substitute
x+2(x+3)+5(20-2x)=64
x+2x+6+100-10x=64
7x=106-64
7x=42
x=6, z=20-2*6=8, z-x=8-6=2

Area = 1/2 * 8 * 8 = 32 in^2
For triangle XYZ,
Area = 1/2* 4 * 12 = 24 in^2

Answer:
The number of fruit bars that people got free at the Beachfront store is 700.
The people in Minnesota and Ohio are 8/10 of the total salespeople. The people in Minnesota are 3/10 of the total salespeople.
Step-by-step explanation:
For the problem about free fruit bars:
The pattern is that 2/3 of the bars that were bought will be free.
To find 2/3, we will first do 1050 ÷ 3 to get 350.
Then we multiply by 2 to get 700.
Therefore, the number of fruit bars that people got free at the Beachfront store is 700.
For the problem about the salespeople:
Counting from the picture, there are 10 total parts. To figure out if a statement is true, confirm with the graph.
ex: Figure out if the statement "the people in Minnesota and Ohio are 8/10 of the total salespeople" is true.
Ohio has 5 parts in the graph. Minnesota has 3 parts in the graph. 5+3=8. Now we put this over 10, the total parts. So, the statement is true.
