300=2×2×5×5×3
We observe that 2 and 5 are grouped in pairs and the 3 is left unpaired.
If we multiply 300 by the factor 3 then
300×3=2×2×5×5×3×3
900=2×2×5×5×3×3 which is a perfect square.
∴ Required number is 3
root of 900 =30
Andre tried to solve the equation 1/4 ( x + 12 ) = 2. What was his mistake? Explain.
1/4x = -10
x = -40
His mistake is that he does not open the bracket first. The value of the x is negative of 4.
What is a BODMAS rule?BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Andre tried to solve the equation 1/4 ( x + 12 ) = 2.
First, open the bracket, then we have
[tex]\dfrac{x}{4} + \dfrac{12}{4} = 2[/tex]
On simplifying, we have
[tex]\dfrac{x}{4 } + 3 = 2[/tex]
Subtract 3 from both sides, we have
[tex]\dfrac{x}{4} = -1[/tex]
Multiply the equation by 4, we have
[tex]x = -4[/tex]

In which equation would you multiply both sides by 4.5 to get the variable alone?
A. 6.1p = 4.5
B. p ÷ 6.1 = 4.5
C. p ÷ 4.5 = 6.1
D. 4.5p = 6.1
Answer:
c.
Step-by-step explanation:
p/4.5 = 6.1
to isolate the variable do the opposite action
p/4.5 = 6.1
as p is divided by 4.5, you must multiply both sides by 4.5
p/4.5 ×4.5 = 6.1 × 4.5
p = 27.45

Jamal's NMI= $ _____

Answer:
:)
Step-by-step explanation:
Since his wage is 8.75*63=551.25, we can add up the percentages to get 10+6.2+1.45+4+0.1=21.75%. To get 21.75%, we can move the decimal 2 to the left to get 0.2175. Multiply that by 551.25 to get around 119.9 dollars. If you'd like to calculate the individual taxes, you can apply a similar process to figure that out

Watermelons cost $1.50 per pound

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 times, how many times would he expect the marble to be blue?
Answer:
[tex]60[/tex] times
Step-by-step explanation:
There are [tex]6+4+3+2=15[/tex] marbles in total. Out of those, [tex]3[/tex] are blue, so the probability of pulling a blue marble is [tex]\frac{3}{15}=\frac{1}{5}[/tex]. However, this is only the probability of pulling a blue marble when [tex]1[/tex] marble is pulled at random. Therefore, we can expect a blue marble to be pulled [tex]\frac{1}{5}*300=60[/tex] times if [tex]1[/tex] marble is pulled [tex]300[/tex] times at random. Hope this helps!

A supermarket marks down the price of a $3.00 loaf of bread by 20%. What is the discount and the new price of the loaf of bread?
Answer:
new price= $2.40
Step-by-step explanation:
20%= 20/100= 1/5
$3.00/5= 00.60
1/5 of the price is being subtracted from $3.00
$00.60 is 1/5
3.00-.60= 2.40
Answer:
The discount is 20% off (you only have to pay 80% of the original price)
The new price of the bread is $2.40 (60 cents off)
Step-by-step explanation:
Because 20 goes into 100, 5 times I did 3.00/5
3.00/5= 0.6
Subtract 0.60 from the 3 dollars and that's it!
3.00-0.60= 2.40

The histogram shows the number of points scored by a basketball team for one season.
Histogram named as ALTDCPoints Scored in One SeasonALTDC. 3 games scored between 69 to 76, 6 games scored between 77 to 84, games scored between 85 to 92 and 1 game scored between 93 to 100.
According to the histogram, in what percentage of games did the team score between 77 and 92 points?
Round your answer to the nearest percent.
The percentage of games did the team score between 77 and 92 points is 78%.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have,
Total games = 3 + 6 + 8 + 1 =18
and, number of games in which points between 77 and 92.
= 6 + 8
= 14
Now, the percentage of games did the team score between 77 and 92 points
= 14/18 x 100
= 77.777%
= 78%
