Answer:

whats your question i dont get it

Step-by-step explanation:

so then 7=42/6 which is 7=7 so True or Yes

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

what you age and send u number

Answer:

0.8

Step-by-step explanation:

The following data were obtained from the question:

Opposite = 3

Adjacent = 4

Hypothenus = 5

Cos R =?

Cosine R can be obtained by using the cosine ratio as illustrated below:

Cos R = Adjacent / Hypothenus

Cos R = 4/5

Cos R = 0.8

Thus, cosine R is equal to 0.8

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.

It has four sides and whatever shape has four sides is a quad. We can also see that it equal sides so it can be both a square and a rhombus. Remember that a rhombus can be both a square and a rhombus.

Answer:

89.559

Step-by-step explanation:

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

Answer:

The fourth one.

Step-by-step explanation:

I am pretty sure.

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.

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

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]

Answer:

C

Step-by-step explanation:

1 1/4 = 1.25

1 4/5 = 1.8

1.8+1.25=3.05=3 1/20

Answer:

C. 3 1/20

Step-by-step explanation:

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
