Answer:
1:2
Step-by-step explanation:
So when finding equivalent ratio in any ratio is finding a common denominator that goes to both numbers for instance:
If you have the ratio 8:16 what is the common factor that can go into both 8 and 16 equally? Well 8 can go into 8 once and 8 can go into 16 twice so lets put this into a problem:
8:16 = (8/8):(16/8) = 1:2
So our equivalent ratio to 8:16 is 1:2.
Hope this helps!!!

2] The band has a ratio of boys to girls of 5 to 4. There are 52 girls in the band.
(Make sure to write out in words first.)
How many are boys?
How many total students?
I need work for both
Answer:
Step-by-step explanation:
For every 4 boys there are 5 girls and 9 students at the school. So that means that 49 of the students are boys. 49 of the total number of students is 120 students:
49×?=120
If 49 the number of students is 120, then 14 of 120 is 19 of the total number of students. In other words, 14×120=30 is 19 the total number of students. Then 9 times this amount will give the total number of students:
9×30=270
So there is a total of 270 students at the school. Note that this is equivalent to finding the answer to the division problem:
120÷49=?
We can see all of this very succinctly by using a tape diagram:
Bar_diagram_67722d3e6005449e4fbe5c57eaad4f3c
There are 4 units of boys and 9 units of students. Therefore 4/9 of the students are boys.
4 units = 120
1 unit = 30
9 units = 270
There are 270 students altogether.
Students can multiply the numbers in the first row by 10 to get the second row, and then double that amount to get the third row. Adding the entries in the second and third row gives the fourth row that has the solution.
Alternatively, since 120÷4=30, students can just multiply the numbers in the first row by 30 to get the values in the fourth row.
In every row, we can see that the fraction of the students that are boys is 49.
looking at the last row, we can see that the total number of students will be 4×30+5×30=120+150=270.

If x=3 and y = ─ 4 , find i) (x─y) ─ y ii) ( x+y) +x 2. Write two pairs of numbers satisfying the equation xꓥ2 + yꓥ2 = 25
Answer:
i) (x -y) -y = 11
ii) (x+y) + x² = 8
iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation x² + y² = 25
Step-by-step explanation:
Step(i):-
Given that x =3 and y=-4
i) (x -y) -y = (3-(-4))-(-4) = 3+4+4 = 11
ii) (x+y) + x² = ( 3 -4) + (3)² = -1 + 9 = 8
Step(ii):-
Given equation
x² + y² = 25
we can choose (x,y) = ( 3 , -4)
3²+(-4)² = 25
25 = 25
The ordered pair ( 3,-4) satisfies the equation
second ordered pair ( 3 ,4)
x² + y² = 25
9 + 16 = 25
25 = 25
Final answer:-
i) (x -y) -y = 11
ii) (x+y) + x² = 8
iii) The two pairs (( 3 , -4)) and ( ( 3 ,4) satisfy the equation x² + y² = 25

In a complete sentence, explain the similarities and differences
between finding circumference when the radius is given and finding
the circumference when the diameter is given.
Answer:
Mathematically speaking, both of these are what are called measures. They are ways of getting at the size of something.
The circumference of a circle is a line, which is one-dimensional, which means it has length but zero width. The area of a circle, in contrast, is two-dimensional. This is the essential difference.
The consequence of this is that circumference is measured in units like centrimetres, or inches, or miles. But area is measured in units like square-centimetres, square inches, or square miles.
Is this what you meant?
Answer:
the circumference is the distance around the circle so u can use the formula c=2πr
the radius formula is r=c/2π
the diameter formula is d=2r

Answer:
Area of a trapezium = 1/2 * sum of parallel sides * distance between them
= 1/2 * (10 + 18) * 6
= 1/2 * 28 * 6
= 84 feet ^2
Area of a rectangle = length * breadth
= 18 * 12
= 216 feet ^2
Total Area = 84 + 216
Total area = 300 feet
Which is an equation of the line parallel to y = 2x + 7 and passes through (-1, 3)?
Answer:
The equation of line parallel to y = 2x + 7 and passes through (-1, 3) is: [tex]y = 2x+5[/tex]
Step-by-step explanation:
Given equation of line is:
y = 2x + 7
The general form of equation in slope-intercept form is:
[tex]y=mx+b[/tex]
Here m is the slope and b is the y-intercept
Comparing the equations, we get
m = 2
Let m_1 be the slope of line parallel to given line
[tex]m_1 = m\\m_1 = 2[/tex]
The equation of line parallel to given line will be:
[tex]y=m_1x+b[/tex]
Putting the value of slope
[tex]y = 2x+b[/tex]
To find the y-intercept, putting (-1,3) in the equation
[tex]3 = 2(-1)+b\\3 = -2+b\\3+2 = b\\b = 5[/tex]
The equation is:
[tex]y = 2x+5[/tex]
Hence,
The equation of line parallel to y = 2x + 7 and passes through (-1, 3) is: [tex]y = 2x+5[/tex]

What triangle makes the statement true? DEF=__
Answer:
c: triangle ABC is congruent to DEF
Step-by-step explanation:
find the triangle with the same side lengths and angle measurements to the given triangle.
The true statement is DEF= ABC
Thus, option (C) is correct.
As, per the figure Triangle DEF.
<DFE= 23
<DEF = 67
<EDF = 90
ED= 5 unit
EF = 13 unit
DF = 12 unit
Now, to find the congruent triangle to DEF.
Look for the triangle which same angles and sides as triangle DEF.
So, In Triangle ABC.
<CBA= 23
<CBA = 67
<BAC = 90
AB= 5 unit
CB= 13 unit
CA= 12 unit
Therefore, the statement is DEF= ABC
Thus, option (C) is correct.

Owen has a square sheet of paper that measures 1 foot on each side. He folds the paper vertically and horizontally so that it makes equal sections. The model below shows the unfolded paper.
Answer:
The areas of the equal sections of boxes formed is 0.25ft^2
Step-by-step explanation:
The question is not complete, as we are not told what to solve for, nevertheless, we can make some findings from the given information
Given data
We are told that the dimension of the paper is 1 ft
So, when the paper is folded twice, one horizontal and one vertical, the dimension of each box will be 0.5 ft
Hence there will be 4 boxes formed
And their areas will be
Area= 0.5*0.5
Area= 0.25ft^2
