what is 39% of 200?
i already know it’s 78, i just need a explanation of how i got it.
Answer:
200 x .39
Step-by-step explanation:
200 x .39= 78
Answer:
39 percent of 200 is the same as 39 per hundred of 200. We can therefore make the following equation:
39/100 = X/200
To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 200, and then finally divide the numerator by the denominator on the right side to get the answer.
39/100 = X/200
X/200 = 39/100
X*200/200 = 39*200/100
X = 7800/100
X = 78
The work above shows the long way to explain how to calculate 39 percent of 200 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 39 percent of 200?", Y is 200 and P is 39:
(200 * 39)/100 = 78
And once again you see that the answer is 78.
Step-by-step explanation:
The number of girls in Mrs. Manning’s classes was 12 less than twice the number of boys. She had a total of 108 students in her classes. How many girls and how many boys are in Mrs. Manning’s classes?
40 boys and 68 girls
let's start with variables and an equation.
boys: x
girls: 2x - 12
and we know that boys and girls make up the class. so let's add the two expressions.
x + 2x - 12 = 108
3x - 12 = 108
+ 12 + 12
3x = 120
x = 40 boys
BUT x is only the number of BOYS in the class. so we have to find girls now. let's plug in our value of x into the girls' equation.
2x - 12 = # of girls
2(40) -12 = # of girls
80 - 12 = # of girls
68 girls
let's check our answer!
68 + 40 does in fact add to 108, therefore our answer is correct.

In the given diagram ⃤ ABC and ⃤ CDE are equilateral triangles. If ∠EBD = 62° then find the measure of 1/2 of ∠AEB.
Answer:
Given
△ABC and △CDE are equilateral.
AE
= 25
To find perimeters of the two triangles,
Let us consider the lengths of
AC
and
CE
to be
′
x
′
and
′
y respectively.
As △ABC is equilateral,
AC
=
AB
=
BC
= x
As △CDE is equilateral,
CE
=
CD
=
DE
= y
From the figure,
AE
=
AC
+
CE
25 = x + y
x + y = 25
Perimeter of the triangle is the sum of all sides of the triangle.
For △ABC,
Perimeter of △ABC =
AC
+
AB
+
BC
= x + x + x
= 3x
For △CDE,
Perimeter of △CDE =
CE
+
CD
+
DE
= y + y + y
= 3y
Now,
Perimeter of two triangles = Perimeter of △ABC + Perimeter of △CDE
= 3x + 3y
= 3 × (x + y)
= 3 × 25 (from above)
= 75
Therefore, Perimeter of the two triangles is'75′units.

How do you solve this problem? What is the answer?
9514 1404 393
Answer:
65 feet
Step-by-step explanation:
The problem involves finding the perimeter of a rectangle, then making adjustments to remove parts of the perimeter that aren't wanted.
The perimeter of a rectangle is given by the formula ...
P = 2(L+W)
For Aubrey's 12' × 8' room, the perimeter is ...
P = 2(12' +8') = 40'
This is the length of the border Aubrey needs at the ceiling.
__
At "waist-high", we need to subtract the total width of all the windows and doors. That total is ...
3' + 4' + 3' + 5' = 15'
So, the waist-high border is 40' -15' = 25'.
__
The total amount of border Aubrey needs is ...
ceiling border + waist-high border = 40' + 25' = 65'.
Aubrey needs 65 feet of border.
A jar contains at least 600 marbles. Two-thirds of the marbles are red. The rest are blue. How many marbles are blue?
Answer:
200 marbles are blue only if there are 600 marbles in total. If there are more than 600, you calculate by dividing the total number of marbles by three.
Answer:
200 blue marbles
Step-by-step explanation:
two-thirds of 600 is 400... so the rest is easy 600-400=200

Answer:
5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying the radicals
[tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex]
[tex]\sqrt{48}[/tex] = [tex]\sqrt{16(3)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]
[tex]\sqrt{12}[/tex] = [tex]\sqrt{4(3)}[/tex] = [tex]\sqrt{4(3)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex]
Then
[tex]\sqrt{27}[/tex] + [tex]\sqrt{48}[/tex] - [tex]\sqrt{12}[/tex]
= 3[tex]\sqrt{3}[/tex] + 4[tex]\sqrt{3}[/tex] - 2[tex]\sqrt{3}[/tex]
= 5[tex]\sqrt{3}[/tex]
Answer:
[tex] \sqrt{27} + \sqrt{48} - \sqrt{12} \\ \sqrt{3 \times 3 \times 3} + \sqrt{2 \times 2 \times 2 \times 2 \times 3} - \sqrt{2 \times 2 \times 3} \\ 3 \sqrt{3} + 4 \sqrt{3} - 2 \sqrt{3} \\ 7 \sqrt{3} - 2 \sqrt{3} \\ \boxed{5 \sqrt{3}} [/tex]

CREATE A SYSTEM OF EQUATIONS AND FIND THE SOLUTION TO 5y-40x=10 y+6x=0
Answer:
x = -1/7
y = 6/7
Step-by-step explanation:
factor a 5 out of the first equation to work with smaller numbers:
y - 8x = 2
let y = -6x (derived from the second equation)
substitute: -6x - 8x = 2
-14x = 2
x = -2/14 or -1/7
find 'y': y - 8(-1/7) = 2
y + 8/7 = 14/7
y = 6/7
Answer:
x = -1/7, y = 6/7
System: [tex]\left \{ {{5y-40x=10} \atop {y+6x=0}} \right.[/tex]
Step-by-step explanation:
The system of equations would be [tex]\left \{ {{5y-40x=10} \atop {y+6x=0}} \right.[/tex].
To find out what x and y are, choose one of the equation and solve for y. Then, substitute the result for y into the other equation.
5y - 40x = 10 (Add 40x to both sides)
5y = 40x + 10 (Divide both sides by 5)
y = 1/5(40x + 10) (Multiply 40x + 10 by 1/5)
y = 8x + 2 (Substitute this for y in the other equation.)
8x + 2 + 6x = 0 (Add 8x to 6x)
14x + 2 = 0 (Subtract 2 from both sides)
14x = -2 (Divide both sides by 14)
x = -1/7 (Substitute this for x in the y = 8x + 2)
y = 8(-1/7) + 2 (Multiply -1/7 by 8)
y = -8/7 + 2 (Convert 2 into 14/7; show as a single fraction)
y = (-8 + 14)/7 (Add -8 and 14)
y = 6/7 (The system is solved)

Math problem :Belvedere swam 35 laps in 1 2 / 3 hours. Find his swimming rate in laps
per hour.
Answer:
21 laps per hour
Step-by-step explanation:
2/3 = 20/30
20/30 × 2 = 40/60
1 and 2/3 = 1 hour 40 mins
60 + 40 = 100 mins
35 (laps) = 100 (mins)
÷10
3.5 = 10
×6
21 = 60
21 laps in 1 hour
so 21 laps per hour
The figure below shows a rectangular prism and a cube:
A rectangular prism and a cube are drawn side by side. The length of the rectangle prism is 6 inches, the width is 5 over 6 inch, and its height is 1 and 2 over 6 inches. The cube has a side length of 1 over 6 inch.
How many such cubes are required to completely pack the prism without any gap or overlap?
Calculate the volume of each shape.
Volume of rectangle = 6 x 5/6 x 1 2/6 = 6 2/3 cubic inches.
Volume of cube = 1/6 x 1/6 x 1/6 = 1/216 cubic inch.
Now divide the volume of the rectangle by the volume of the cube:
6 2/3 / 1/216 = 1440
It will take 1.440 cubes to fill the rectangle.

Ratio of coefficient of y= ratio of coefficient of x = ratio of constants.
Given system: [tex]y=2x+a[/tex]
[tex]y=bx-3[/tex]
It it has infinitely many solutions, then
[tex]\dfrac{1}{1}=\dfrac{2}{b}=\dfrac{a}{-3}\\\\\Rightarrow\ \dfrac{2}{b}=1\ \ \ \text{ and }\ \ \dfrac{a}{-3}=1\\\\\Rightarrow\ b=2\ \ \ \text{ and } \ \ a=-3[/tex]

Write the number as a quotient of integers to show that it is rational.
300= ?/?
Answer:
300 is a rational number because it can be expressed as the quotient of two integers: 300 ÷ 1.
Step-by-step explanation:
The number [tex]300[/tex] can be written as [tex]\frac{300}{1}[/tex] as a quotient of integers to show that it is rational.
A rational number is a number of the form [tex]\frac{p}{q}[/tex], where [tex]q \ne0[/tex] and [tex]p[/tex] and [tex]q[/tex] must be co-primes.
To write a number in the form of quotient of integer, we write it as [tex]\frac{p}{q}[/tex], where [tex]q \neq 0[/tex].
Here, [tex]300[/tex] can be written as [tex]\frac{300}{1}[/tex] or [tex]\frac{600}{2}[/tex]or [tex]\frac{900}{3}.[/tex]
But we should also take care that [tex]p[/tex] and [tex]q[/tex] must be co-primes.
Co-primes are the pairs of numbers that have only one common factor which is [tex]1[/tex].
So, [tex]300[/tex] can be written as [tex]\frac{300}{1}.[/tex]

Answer:
15x +6y = 21. is equal to 07x +6y = -3. is equal to 0Step-by-step explanation:
15x +6y = 2 is equal to 0 because when we move the constant to the left and divide both sides of the equation by 3 we get:
5x + 2y - 7 = 0Same with 7x +6y = -3, when we move the constant to the left and sum the two opposites equal to 0 it give us:
7x + 6y + 3 = 0
