Answer:

E

Step-by-step explanation:

let a, b, c represent the number of students in 6th, 7th, 8th grade

ratio of students : teachers = 28 : 1

There are 82 teachers , so 28 × 82 = 2296 students

Then

a + b + c = 2296 , that is

828 + b + c = 2296 ( subtract 828 from both sides )

b + c = 1468 → E

Step-by-step explanation:

The area of the parallelogram is given by the distance formula and the value of A = 13 square units

Let the two points be A ( x₁ , y₁ ) and B ( x₂ , y₂ )

The distance from A to B is the same as the distance from B to A

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

This formula is used to find the distance between any two points on a coordinate plane or x-y plane

Given data ,

Let the parallelogram be ABCD

Let the height of the parallelogram be AD

And , the base of the parallelogram be DC

where the area A = AD x DC

Now , the coordinates of A = A ( 3 , 6 )

The coordinates of D = ( 2 , 2 )

The coordinates of C = C ( 5 , 1 )

The distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

So , the distance of AD = √ ( ( 3 - 2 )² + ( 6 - 2 )² )

The distance of AD = height of parallelogram AD = √17

And , the distance of DC = √ ( ( 2 - 5 )² + ( 2 - 1 )² )

So , the distance of DC = width of parallelogram DC = √10

And , area of parallelogram A = AD x DC = √17 x √10 = √170 units²

Hence , the area of parallelogram is A = 13 square units

Answer:

∠ E = 57°

Step-by-step explanation:

Since DF = EF then the triangle is isosceles with 2 base angles congruent , so

∠ E = ∠ D = 4x + 1

The sum of the 3 angles in the triangle = 180°

Sum the 3 angles and equate to 180

4x + 1 + 4x + 1 + 5x - 4 = 180 , collect like terms

13x - 2 = 180 ( add 2 to both sides )

13x = 182 ( divide both sides by 13 )

x = 14

Then

∠ E = 4x + 1 = 4(14) + 1 = 56 + 1 = 57°

First row = 3

Second row = 12

===================================================

Explanation:

Think of a square that has sides of 5 by 5. It's area will be 5*5 = 25. That means 25 is a perfect square.

We rule out 81 for similar reasons because 81 = 9*9

Also, 100 = 10*10 and 121 = 11*11

The only thing left is 3 which isn't a perfect square. We cannot multiply two of the same whole number to end up with an area of 3 square units.

Put another way, [tex]\sqrt{3}[/tex] is not a whole number while something like [tex]\sqrt{81} = 9[/tex] is a whole number.

This is all for the first row.

--------------------------

The second row is the same story.

4 = 2*2

9 = 3*3

144 = 12*12

36 = 6*6

This rules out everything but 12 in the second row. You can determine what is a perfect square through trial and error, or by memorizing what the perfect square numbers look like. With enough practice, they should be fairly memorized by some point.

Answer:

y-intercept is (0, -4)

x-intercept is (-5, 0)

Step-by-step explanation:

Remember the x-intercept and the y-intercept are the points on the graph where the line crosses the x-axis and the y-axis respectively.

We can find the x intercept and the y intercept a couple of ways. One way is to graph the line, which I will do later. The other way is to do a little math.

The equation of a line in y-intercept form is

[tex]y = mx + b[/tex]

where b = the y-intercept

In our equation above and solving for y we get the y-intercept is -4

[tex]4x + 5y = - 20 \\ 5y = - 4x - 20 \\ y = - \frac{4}{5} x - 4[/tex]

Doing more algebra and solving for x we get the x intercept is negative 5.

[tex]y = - \frac{4}{5} - 4 \\ y + 4 = - \frac{4}{5} x \\ x = - \frac{5}{4} y - \frac{20}{4 } \\ x = - \frac{5}{4} y - 5[/tex]

Answer:

When a transversal crosses parallel lines, corresponding angles are congruent.

Step-by-step explanation:

When a transversal crosses parallel lines, corresponding angles are congruent can be used to prove that LM and NO are parallel lines

An angle is formed from the intersection of two or more lines. Types of angles are acute, obtuse and right angle.

If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.

Hence, When a transversal crosses parallel lines, corresponding angles are congruent can be used to prove that LM and NO are parallel lines

Answer:

length of arc ≈ 17.8 (to the nearest tenth)

Step-by-step explanation:

To find the length of the arc we use the formula for finding length of an arc.

length of arc = ∅/360 × 2πr

where

∅ = central angle

r  = radius

∅ = 340°

r = 3

length of arc = ∅/360 × 2πr

length of arc = 340/360 × 2 × π × 3

length of arc = 340/360 × 6π

length of arc = 2040π/360

length of arc = 204π/36

length of arc = (204 × 3.14)/36

length of arc = 640.56/36

length of arc = 17.7933333

length of arc ≈ 17.8 (to the nearest tenth)

there's 5 piece but 6 people. everyone would get less then an equal piece.

5÷6= 0.833333 or in fraction 5/6.

if you divide 6 people and 5 pieces you get 1.2 size piece. that's more then the cake has, which is 5 pieces. That's what I think.
