Step-by-step explanation:
At middle school lunch in the cafeteria, 60% of the students pack a lunch and 40% buy a lunch. Of the students who pack a lunch, 70% have a cookie. What is the percent of the students who have a cookie at lunch?
Answer:
42%
Step-by-step explanation:
The computation of the percentage is shown below:
Here we assume that there are 100 students
So according to the question
60% of the students would pack the lunch i.e. 60 students
And, 40% of the students buy a lunch i.e. 40 students
Now the students who pack the lunch they have 70% of cookie
So, 70% of 60 students = 42 students
Now the percentage is
= 42 students ÷ 100 students
= 42%

Which is the most accurate way to estimate 66% of 46?
A: 2/3 x 47
B: 1/3 x 45
C: 1/3 x 47
D: 2/3 x 45
Answer:
30 Don't use your calculator.
Step-by-step explanation:
This is an estimation question, so you have to throw your calculator out of your reach.
You have to know that 66% is nearly 2/3 So the correct answer cannot be B or C
It must be A or D.
The problem is that 3 doesn't go into 46 so you have to change it to something that is divisible by 3. Of the numbers given, the best one is 45
2/3 * 45 = 2 * 15 = 30
How close is that (remember you have to give 30 as your answer)?
The actual answer is 30.36 which makes your estimate very good.

which polynomial is a perfect square trinomial?
A. 49x^2 - 28x + 16
B. 4a^2 - 20a + 25
C. 25b^2 - 20b - 16
D. 16x^2 - 24x - 9
Answer:
B
Step-by-step explanation:
We have to find which trinomial has:
1) two terms that are the perfect square of two numbers
2) a terms that is the double product of the two numbers
the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2
Options C and D are traps because the square of a number can’t be negative

Alicia will construct a rectangle that has a height of 4 units and an area of up to 48 square units. Which inequality represents all the possible lengths in units of the bases, b, that Alicia can use to construct this rectangle?
Answer:
b ≤ 12
Step-by-step explanation:
The area of the rectangle is given by length multiplied by breadth.
The area of the rectangle up to 48 units square means that it can be 48 or less than 48.
If the height given is taken as the width of the rectangle then we can find the base which will be the length of the rectangle.
Area = length * breadth
4units * base ≤ 48 units square
base ≤ 48 units square/4 units
base ≤ 12 units
b ≤ 12 units
Sarah uses 2 eggs for each batch
of 12 muffins that she bakes. How
many muffins can she bake with a full
carton of 12 eggs?
Answer:
I think it would be 72
Step-by-step explanation:
You would have to divided 2 by 12, which is 6. Then, you would have to multiply 6 by 12, which i s 72. I hope this is right, if not I'm sorry. I really hoped this helped :D

The acceleration (in m/s/s) of a body is directly proportional to the force (in N for newton) acting on the body. If a certain body accelerates at 10 m/s/s when subjected to a force of 3 N, what will the acceleration be under a force of 8 N??
Answer:
26.667
Step-by-step explanation:
Force is directly proportional to mass and acceleration.
So Let's first bring the parameters.
F=3N, A=10m/s M=?
F=ma:.
3=Mx10,. 3=10M
M=3/10 M= 0.3
So we will use that to find the acceleration of force 8N.
F=Ma:. 8=0.3xa
8=0.3a
A=8/0.3
A=26.667.

Nick needs to raise at least $320 for his trip. He has $80 saved already, and he makes $40 per yard that he mows. Write and solve an inequality to solve for how many yards, "x," Nick must mow to earn the money.
Answer: Nick must now at least 6 yards.
Step-by-step explanation:
Since Nick has $80 saved already, and he makes $40 per yard that he mows, thus can be put up in an equation as:
= 80 + 40y
where y = number of yards
Since Nick needs to raise at least $320 for his trip, the equation to solve this will be:
80 + 40x ≥ 320
40x ≥ 320 - 80
40x ≥ 240
x ≥ 240/40
x ≥ 6
Therefore, Nick must now at least 6 yards.

In the diagram ABC is congruent to DEF. aging the values of x and y
Answer:
x = 1, y = 46
Step-by-step explanation:
Since the triangles are congruent then corresponding sides and angles are congruent, then
DE = AB , that is
3x + 6 = 9 ( subtract 6 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
and
∠ C = ∠ F
10x + y = 56 ( substitute x = 1 )
10(1) + y = 56
10 + y = 56 ( subtract 10 from both sides )
y = 46
