What is the best estimate of 11% of 448?
Answers
Answer:
49.28.
Step-by-step explanation:
11% = 10% + 1%
So 11% of 448 = 44.8 + 4.48
= 49.28.
The best estimate of 11% of 448 is 49.28.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred.
11% of 448 = 11 / 100 × 448 = 0.11 × 448
= 49.28
Hence, the best estimate of 11% of 448 is 49.28.

Find the equation of a line which is parallel to the line with the equation 2x + y = 4 and
which passes through the origin.
Answers
Answer:
y = -2x
Step-by-step explanation:
Given
2x + y = 4Passes through the origin (0, 0)Solving
Rewriting the equation
2x + y = 4y = -2x + 4New equation
The slope of the new line is the same (-2) because it is parallelThe y-intercept is (0, 0)⇒ y = mx + b [m = slope, b = y-intercept]
⇒ y = -2x + 0
⇒ y = -2x
Answer:
2x+y=0
Step-by-step explanation:
Given:
\(\displaystyle \large{2x+y=4}\\\displaystyle \large{y=-2x+4}\)
To find:
The equation of line that’s parallel and passes through origin point.Parallel Definition:
Both lines have same slope.Slope-Intercept:
\(\displaystyle \large{y=mx+b}\)
m = slopeb = y-interceptTherefore, another line is:
\(\displaystyle \large{y=-2x+b}\)
Since the line passes through origin point which is (0,0). Substitute x = 0 and y = 0 in the equation:
\(\displaystyle \large{0=-2(0)+b}\\\displaystyle \large{b=0}\)
Therefore, the equation is:
\(\displaystyle \large{y=-2x}\)
Convert back to standards form:
\(\displaystyle \large{2x+y=0}\)
Therefore, another line that is parallel to \(\displaystyle \large{2x+y=4}\) is 2x+y=0

Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666...

8p + -4p = 2p + 6
Combine like terms: 8p + -4p = 4p
4p = 2p + 6
Reorder the terms:
4p = 6 + 2p
Solving
4p = 6 + 2p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-2p' to each side of the equation.
4p + -2p = 6 + 2p + -2p
Combine like terms: 4p + -2p = 2p
2p = 6 + 2p + -2p
Combine like terms: 2p + -2p = 0
2p = 6 + 0
2p = 6
Divide each side by '2'.
p = 3

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

A music store is having a clearance sale. All items are discounted by 20%. What is the sale price of a radio that regularly costs $30?
Answers
Answer:
24
Step-by-step explanation:
You would first multiply 20% by $30. Then you would get 6 and subtract 6 from $30.
Answer:
$24
Step-by-step explanation:
Method 1: find 10% of 30 = 3 (just divide 30 by 10)
then double it to make 20% = 6
subtract 6 from 30 to give 24.
Method 2: 20% = 1/5
To find 1/5 of a number, divide it by 5.
30 divided by 5 = 6.
Then subtract 6 from 30 = 24.
Method 3: to decrease a number by 20% multiply it by 0.8.
30 x 0.8 = 24

He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
He did not multiply the numerator and denominator by the correct number to equal 1,500.
His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion.
He can only solve the proportion by multiplying the numerator and denominator by a common multiple.
He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

Step-by-step explanation:
After dylan took half of the cookies and 6 were left there were
12 before he took any
Than If Koji took a 3rd when 12 were left there were 18
Than if Paige took a 1/4 of what was left when there were 18 there were 24

24+6 = 30 and than 30+6 = 36

Mrs. Balbas makes a batch of cookies for her math class. Aaron takes 1/6 of the cookies and runs out the door. Matthew then takes 1/5 of the cookies that are left. Paige takes 1/4 of what remains after Matthew leaves. Koji takes 1/3of what remains after Paige, and then Dylan grabs half of the remaining cookies after Koji. Gavin then swoops in and grabs the last remaining 6 cookies then the batch initially had 432 cookies.
Mrs. Balbas baked a batch of cookies for her math class.
1. Aaron takes 1/6 of the cookies:
If "C" represents the initial number of cookies, Aaron takes (1/6)C cookies, leaving (5/6)C cookies.
2. Matthew takes 1/5 of the remaining cookies:
Matthew takes (1/5)(5/6)C = (1/6)C cookies, leaving (5/6)C - (1/6)C = (2/3)C cookies.
3. Paige takes 1/4 of the remaining cookies:
Paige takes (1/4)(2/3)C = (1/6)C cookies, leaving (2/3)C - (1/6)C = (1/2)C cookies.
4. Koji takes 1/3 of the remaining cookies:
Koji takes (1/3)(1/2)C = (1/6)C cookies, leaving (1/2)C - (1/6)C = (1/3)C cookies.
5. Dylan takes half of the remaining cookies:
Dylan takes (1/2)(1/3)C = (1/6)C cookies, leaving (1/3)C - (1/6)C = (1/6)C cookies.
6. Gavin takes the last 6 cookies:
The remaining (1/6)C - 6 cookies are taken by Gavin.
7. The rest of the class gets nothing, leaving 0 cookies.
Now, let's add up the amounts taken by each student:
- Aaron: (1/6)C
- Matthew: (1/6)C
- Paige: (1/6)C
- Koji: (1/6)C
- Dylan: (1/6)C
- Gavin: 6 cookies
Adding all these together, we get:
(1/6)C + (1/6)C + (1/6)C + (1/6)C + (1/6)C + 6 = (5/6)C + 6
Since the remaining cookies are accounted for,
we know that (5/6)C + 6 = 0, which gives us C = 432.
Therefore, the initial batch had 432 cookies.
