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.
What is the equation for the line of reflection? On a coordinate plane, image A B C D has points (2, 2), (7, 3), (5, 1), (4, 1). Image A prime B prime C prime D prime has points (10, 2), (5, 3), (7, 1), (8, 1). x = 6 y = 6 y = x y = 2 Mark this and return
Answers
The equation of the line of reflection should be .
Given information:
Triangle ABC has points (6, 3.7), (5.4, 2), (1, 3). Triangle A' B'C' has points (3.7, 6), (2, 5.4), (3, 1).
A'B'C' is the reflection of the triangle ABC.
It is required to find the equation of the line of reflection.
Now, from the given coordinates of triangle ABC and its reflection, it is clear that the x and y-coordinates have interchanged their values. For example, coordinate (6,3.7) has become (3.7,6).
Therefore, the equation of the line of reflection should be .
The midpoint between (2, 2) and (10, 2) is ((2 + 10) / 2, (2 + 2) / 2), which simplifies to (6, 2). The midpoint between (7, 3) and (5, 3) is ((7 + 5) / 2, (3 + 3) / 2), which simplifies to (6, 3). The midpoint between (5, 1) and (7, 1) is ((5 + 7) / 2, (1 + 1) / 2), which simplifies to (6, 1). Finally, the midpoint between (4, 1) and (8, 1) is ((4 + 8) / 2, (1 + 1) / 2), which simplifies to (6, 1).
The line of reflection is the line that passes through each pair of midpoints. Since all four midpoints have the same x-coordinate of 6, the line of reflection is a vertical line passing through x = 6.
Therefore, the equation for the line of reflection is:
x = 6

Answer:
54
Step-by-step explanation:
[tex] < 2 = 180 - 109 \\ = 71 \\ < 1 = 180 - 71 - 55 \\ = 54[/tex]
The measure of ∠1 is 54 degrees by angle sum property
We have to find measure of angle 2 before finding angle 1 ∠1
∠2 + 109 = 180
Subtract 109 from both sides
∠2 = 180-109
∠2 =71 degrees
From angle sum property theorem we know that in any triangle the sum of angles is 180 degrees
∠1 + 71 +55 = 180
∠1 + 126 =180
Subtract 126 from both sides
∠1 = 180-126
One hundred eighty minus one hundred twenty six is equal to fifty four degrees
∠1 = 54 degrees
Hence, the measure of ∠1 is 54 degrees by angle sum property

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.

Answer:
∡4 = 146°
Step-by-step explanation:
First, we need to find the value of ∡2, and keep in mind that the sum of all the angles in a triangle is = 180°.
Since the triangle is a right angle, we know that the angle to the bottom right = 90°. The other angle is 56°.
Since there are only 3 angles, let's add 56° and 90° to find ∡2.
56 + 90 = 146
180 - 146 = 34°
∡2 = 34°.
Now that we've found ∡2, we need to find out what type of angles ∡4 and ∡2 are.
They are supplementary angles, since they add up to 180°.
Let's subtract 180 - 34 to give us the value of ∡4
180 - 34 = 146
Therefore ∡4 = 146°

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.

The owner of a tea shop is making a blend of two teas. Tea A costs $5.40 per pound. Tea B costs $6.80 per pound. The owner wants to make 8 pounds of the blend and wants to sell it for $5.75 per pound. How much of each tea should he use?
Answers
12 pounds of tea-1 and 8 pounds of tea-2 should be used.
Step-by-step explanation:
Let the mass of the tea-1 be x and tea-2 be y.
Total mass of mixture tea owner wants to make = 20
pounds
x+y = 20 ... [1]
Cost of 1 pound of tea-1 = $6.50
Cost of 1 pound of tea-2 = $4.00
Cost of the 1 pounds mixture = $5.50
₴ × $6.50 + y × $4.00 = 20 × $5.50
6.5× + 4.00y = 110... [2]
Solving equation [1] and [2] by substitution method, putting value of × from [1] in [2].
X=20 - y
6.5(20 - y) + 4.00y = 110
130 - 6.50y + 4.00y = 110
-2.5 y=-20
y = 8
×=20-y = 20-8 = 12
12 pounds of tea-1 and 8 pounds of tea-2 should be used.

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

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
Which situation is best represented by the following equation
68.50x + 127.95 = 675.95
Answers
Answer: Option B
Step-by-step explanation:
Considering Option A
we can infer that the office manager paid a total of $675.95
the cost of the software package is $68.50
while an employee is paid $127.95 every hour she works on the website
So, the equation for this situation goes like this: 68.50 + 127.95x = 675.95
Coming to Option B
we can infer that the office manager paid a total of $675.95
the cost of one monitor is $127.95
while the hard drives are for $68.50 each
So, the equation for this situation goes like this: 68.50x + 127.95 = 675.95
Hence Option B is the correct answer

Determine the measurement of EF.
EF = 1.58
EF = 1.52
EF = 1.1
EF = 5.5
Answers
Answer:
EF = 1.58
Step-by-step explanation:
Since DE is provided (2.2), we use that in order to find EF.
First, divide the length of AB by the length of DE.
11 ÷ 2.2 = 5
So we use 5 to figure out the measurement for EF.
BC = EF, so we divide BC by 5 to get EF.
7.9 ÷ 5 = 1.58
therefore EF = 1.58
Answer:
EF is equal to 1.58
Take 11 and divide it by 2.2 to get 5, then divide 7.9(BC) and 5 which is 1.58(EF)
