Answer:

67 tickets (with $5 extra)

Step-by-step explanation:

1000÷15= Number of tickets

Step-by-step explanation:

yes,

as AB = CD Which means both their values are same

CD = EF ( which also means their values are same)

as, AB have same values as CD and EF also have same values as CD so,

AB = EF.

Answer:

77 degrees and 90 degrees

The angle d is shown as 90 by the perfect right angle. The angle e has to equal 180 when added to f. So 180-103=77.

Answer:

y=2x-3

Step-by-step explanation:

refer to picture plz

Answer:

the desired equation is y = 2x - 3

Step-by-step explanation:

Parallel lines have the same slope.  Thus, a new line parallel to y = 2x - 4 has the slope 2.  

Find the equation of the new line by writing out the slope-intercept form

y = mx + b.  Substitute -1 for y and 1 for x:

-1 = 2(1) + b, which yields b = -3

Then the desired equation is y = 2x - 3

According to above diagram :

RT = RS + ST

that is :

now, RT = 2x + 75

hence , RT = 31 units

Answer:

RT = 31

Solve for x:

[tex]x=-22[/tex]

Step-by-step explanation:

==>> The sum of the line is RST

[tex]4x+107+12=RST[/tex]

==>> Since [tex]RST = 2x + 75[/tex], the equation will newly become [tex]4x+107+12=2x+75[/tex]

--

To find [tex]4x+107[/tex], we need to find the x.

==>> [tex]x=-22[/tex]

-- Lets check our work

==>> [tex]4(-22) = -88[/tex]

[tex]-88 + 107 = 19 [RS = 19][/tex]

[tex]RS + ST = 19 + 12 =[/tex] 31

--

[tex]2(-22) = -44[/tex]

[tex]-44 + 75 =[/tex] 31

31 = 31

The proportional relationship is given by y = 8.5x

Two variables are said to be proportion if an increase/decrease in one variable causes an increase/decrease in the other variable.

Let x represent the movie tickets and y represent the cost.

Since x and y are proportional, hence:

y ∝ x

y = rx

Where r is the constant of proportionality.

From the table to find x, when y = 17, x = 2, hence:

17 = 2r

r = 8,5

y = 8.5x

The proportional relationship is given by y = 8.5x

Explanation:

Parallel lines always have equal slopes, but different y intercepts. For example, the two lines y = 3x+5 and y = 3x+7 have a slope of 3. Refer to y = mx+b where m is the slope. Parallel lines never intersect.

-----------

For perpendicular lines, the two slopes always multiply to -1 assuming neither line is vertical nor horizontal. Consider the two linear equations

y = (1/2)x+5

y = -2x-7

The slopes 1/2 and -2 multiply to -1 which is enough to show that they are perpendicular lines. The two lines meet at a 90 degree angle.

To go from one slope to the other, we apply the negative reciprocal. That means we...

Applying the first step to 1/2 gets us 2/1 or 2. Then changing the sign has us go from 2 to -2. This process can be reversed.

-----------

For some of these equations, you'll need to rearrange things into either point-slope form or slope intercept form. This will allow you to read off the slope.

Point slope form is y-y1 = m(x-x1)

Slope intercept form is y = mx+b

For either case, all we care about is the variable m.

I'll show how problem 14 transforms into slope intercept form

x+2y = 14

2y = -x+14

y = (-x+14)/2

y = (-x/2) + (14/2)

y = (-1/2)x + 7

We see that m = -1/2 here. Anything parallel to this will have the same slope. The perpendicular slope is 2 after applying the negative reciprocal operation. Problems 13, 15, 16, 17, and 18 are going to follow similar steps.

Answer:

The constant factor between consecutive terms of a geometric sequence is called the common ratio.

Example:

To find the common ratio , find the ratio between a term and the term preceding it. r=42=2. 2 is the common ratio.

Answer:

96 strawberries (c)

Step-by-step explanation:

the ratio from strawberry to tart:

4:1

the ratio if we have 24 tarts:

?:24

from multiplying the tart by 24 we must multiply the strawberries by 24 making the ratio:

96:24

Original line: y = -5/6x - 1

A line that is parallel to the original will have the same slope. To find the new y-intercept, we'll take the original line, plug in the given point, and solve for b.

y = -5/6x + b

-2 = -5/6(5) + b

-2 = -25/6 + b

b = 13/6

Parallel Line: y = -5/6x + 13/6

A line that is perpendicular to the original will have the opposite reciprocal slope. To find the new y-intercept, we'll take our perpendicular slope, plug in the given point, and solve for b.

y = 6/5x + b

-2 = 6/5(5) + b

-2 = 6 + b

b = -8

Perpendicular Line: y = 6/5x - 8

Answer:

[tex]x = \frac{1}{2}y[/tex] or [tex]y = 2x[/tex]

Step-by-step explanation:

Basically, x is 2 times smaller than y, or

y is 2 times larger than x.

For example, when x equals 4, y is 2 times greater, so y = 4 * 2 = 8

Another example:

When y equals 12, x must be 2 times smaller than that, so x = 12 / 2 = 6

I don't know which one you're looking for, but try putting in

x = 1/2y or y = 2x

Step-by-step explanation:

substituting in the values of s, b,t and n in the expression then,

Answer:

21.413

Step-by-step explanation:

Change the divisor 0.63512 to a whole number by moving the decimal point 5 places to the right. Then move the decimal point in the dividend the same, 5 places to the right.

We then have the equations:

1360000 ÷ 63512 = 21.413

and therefore:

13.6 ÷ 0.63512 = 21.413

Both calculated to 3 decimal places.
