Aleks04 [339]2 years ago

Answer:

Step-by-step explanation:

Solving simultaneously

14v + 12b = 612 .....(1)

7v + 13b = 516 ......(2)

eqn (1) - [eqn (2) x 2]

14v + 12b = 612 ...(1)

14v + 26b = 1,032 ...(3)

-14b = -420

b = 30

7v + 13(30) = 516

7v + 390 = 516

7v = 126

v = 18

therefore 1 bus carries 30 students and 1 van carries 18 students

Circle O is shown. Line segments B O and O C are radii. Point A is on the circle and is not within angle B O C.
Paha777 [63]

The ratio of major to minor arc = 2 : 1

What is a Circle?

A circle is the locus of a point such that its distance from a fixed point (center) is always constant.

Calculation

The length of an arc (L) with center angle θ is given by:

                                          L = (θ/360) * 2πr

where r is the radius.

Putting the values in the above formula.

For the major arc:

L = (240/360) * 2πr

For the major arc:

l = ((360-240)/360) * 2πr

l = (120/360) * 2πr

The ratio of major to minor arc = [(240/360) * 2πr] / [(120/360) *2πr] = 2 : 1

The ratio of major to minor arc = 2 : 1.

The last net has all of the requirements. All you have to do then is count, which means the vertices from the hexagon all add up to 12. The rectangles are supposed to encircle it to make a closed object, which gives it eight faces, hexagons included.

Answer:

  B

Step-by-step explanation:

Given the triangle congruence statements, the segment and angle congruence statements must refer to corresponding vertices. Corresponding vertices are listed in the same order in the triangle congruence statement.

The one FALSE statement in the bunch is ...

  \overline{OD}\cong\overline{AL}

__

The true statements for these segments would be ...

  \overline{OD}\cong\overline{JL}\\\\\overline{CD}\cong\overline{AL}

What equation is represented by the equation on the graph ?
solmaris [256]

Answer: The correct option is D.

Explanation:

From the graph we noticed that the x intercept of the line is (2,0) and the y-intercept is (0,2).

If the line passing through two points then the equation of line is,

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Since the ien passing through (2,0) and (0,2).

y-0=\frac{2-0}{0-2}(x-2)

y=-1(x-2)

y=-x+2

This equation is represented by option D, therefore the option D is correct.

Write a linear function f with f(−10)=4 and f(−2)=4.
Orlov [11]

f(-10) = 4

f(-2) = 4

Since y is constant while x isnt we just dont need to put x

f(x) = 4
