Find x and y with ray theorem

Answer:

answer is A i and iv

two sides meet at 90°

two sides are equal in lenght

[tex]==================================[/tex]

the given equation is written in slope-intercept form, which looks like so:

[tex]\pmb{y=mx+b}[/tex]

where

[tex]\pmb{m}[/tex] is the slope of the line

[tex]\pmb{b}[/tex] is the y-intercept of the line

in order to determine the slope & the y-intercept, just look at the equation:

[tex]\pmb{y=3x-7}[/tex]

slope: [tex]\pmb{3}[/tex]

y-intercept: [tex]\pmb{-7}[/tex] or ( [tex]\pmb{0, -7}[/tex])

Answer:

Number of people in the conference on first day = 45

It increased by 40% the second day.

To find:

The number of people in the conference on second day.

Solution:

The conference had 45 people and it increased by 40% the second day. So,

Number of people in the conference on second day [tex]=45+40\%\ of\ 45[/tex]

                                                                                        [tex]=45+\dfrac{40}{100}\times 45[/tex]

                                                                                        [tex]=45+18[/tex]

                                                                                        [tex]=63[/tex]

Therefore, the number of people in the conference on second day is 63.

Answer:

C

Step-by-step explanation:

250 represent the amount of money that they started off with

1.05 represent how much the money in the account is increasing by

and x represent the amount of months that have passed

Answer:

D) 32,357mm^3

Step-by-step explanation:

Given

[tex]Quarters = 40[/tex]

[tex]Thickness = 1.75mm[/tex]

[tex]diameter = 24.26mm[/tex]

First, we calculate the volume of 1 roll.

The volume of the cylinder is:

[tex]V = \pi r^2h[/tex]

Where

[tex]r = \frac{1}{2} * diameter[/tex]

[tex]r = \frac{1}{2} * 24.26mm[/tex]

[tex]r = 12.13mm[/tex]

And the thickness represents the height.

So:

The volume is:

[tex]V = 3.142 * 12.13^2 * 1.75[/tex]

[tex]V = 809.03mm^3[/tex]

The volume of the 40 is:

[tex]Roll= 40 * 809.03mm^3[/tex]

[tex]Roll=32361.20mm^3[/tex]

Answer:

  9 square units

Step-by-step explanation:

Pick's theorem is a useful relationship in circumstances like these. It tells you the area is ...

  A = i + b/2 - 1

where i is the number of interior points (8), and b is the number of points on the border (4).

The area of this figure is ...

  A = 8 + 4/2 -1 = 9

The area of the polygon is 9 square units.

_____

You can also get there by realizing the bounding rectangle is 4 units square. From that, corner triangles are cut. CW from upper left, those triangles have (base, height) dimensions of (3, 2), (1, 3), (3, 1), and (1, 2). So, the total of their areas is (1/2)(6 +3 + 3 +2) = 7 square units. The shaded area is then 16-7 = 9 square units, same as above.

Answer:

2x° = 45°, 3x° = 67.5°

Step-by-step explanation:

Sum of angles in a triangle = 180°

2x+3x+3x=180°

8x=180°

x=22.5°

2x=22.5°x2=45°

3x=22.5°x3=67.5°

b) JN=4ft

Answer: 18 miles west

Step-by-step explanation:

The mall is west of the highway.

The hospital is then west of the mall.

If the hospital is west of the mall which is already to the west of the highway, the Hospital must be west of the highway as well.

The hospital is 12 miles west of the mall which is then 6 miles west of the highway. As they are both west, it is a continuous distance and we can simply add their distances up and assume the distance is linear.

The distance between the hospital and the highway is therefore:

= 12 + 6

= 18 miles west

Answer:

B

Step-by-step explanation:

They both equal 121

Answer:

b) 13

Step-by-step explanation:

67 - 55 = 12

55 - 46 = 9

46 - 34 = 12

34 - 25 = 9

25 - x = 12

rearrange that so,

25 - 12 = x

x = 13

Answer:

b) 13

Step-by-step explanation:

67 - 12 = 55

55 - 9 = 46

46 - 12 = 34

34 - 9 = 25

pattern: subtract 12, subtract 9

the pattern tells us to subtract 12, so take take 25 and subtract 12 from it:

25 - 12 = 13

Answer:

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect

Answer:

900<x<1100

Step-by-step explanation:

The third side must be greater than the difference of the other two sides

10000- 1000 < 10x

9000< 10x

Divide by 10

9000/10 < x

900 < x

The third side must be smaller than the sum of the other two sides

10000+1000 > 10x

11000>10x

Divide by 10

11000/10>10x/10

1100>x

900<x<1100

Answer:

3125 bacteria

Step-by-step explanation:

Let r(0) be the initial amount of bacteria. Every hour, r(n) decreases by half. So, after one our new value for r(n) = (1/2)r(0). After two hours, r(n') =  (1/2)r(n) =  (1/2)(1/2)r(0) = (1/2)²r(0).

After n hours, r(n) = (1/2)ⁿr(0)

So when n = 4 hours and r(0) = 50,000, then

r(4) = (1/2)⁴r(0)

r(4) = (1/2)⁴ × 50,000

r(4) = (1/16) × 50,000

r(4) = 3125

So, after 4 hours, we have 3125 bacteria present.

Answer:

140 feet squared

Step-by-step explanation:

Let's do this step by step. First, let's find the area of the rectangle, which is 8 times 10. It equals 80. Next, do the trangle. 6 times 10 is 60. So, 60 plus 80 equals 140.

Answer:

area of rectangle =L*B

8*10=80ft^2

area of triangle=1/2b*h

h is 8 ft

1/2*6*8

3*8

24ft^2

total area is 80+24

104ft^2

nearest tenth = 100 ft^2
